There is new toxic mom group drama starring Ashley Tisdale and Hilary Duff husband

Posted on by

Beef looks very different these days for some former teen actors from 2000s.

The return of low rise jeans and trucker hats the world can now revel in what appears to be drama between two former Disney channel stars.

The Cut published a personal essay from actress Ashley Tisdale last week title Breaking Up With My Toxic Mom Group.

The star famous for her work on The Suite Life of Zack and Cody and High School Musical franchise wrote about how she and some friends had formed a group chat to talk about being new mother after all being pregnant through the early pandemic and mission out on activeness you meet other expectant mothers.

He added  a sub headline that read  A Mom Group Tell All Through A Father Eyes” consisting as caption Read my new interview with The Cut.

Duff who starred in Disney Channel hit series Lizzie McGuire as teen married Koma who is in band Winnetka Bowling League in 2019 and they are parents of three young daughters.

She shares a son with her ex husband Mike Comrie.

Tisdale essay for The Cut is not her first on subject to go viral.

In December 2025 a post on blog headline.

She recalled other times being left out and feeling distance from group all of which made her wonder why me.

The truth is I do not know and i probably never will. What I do know is that it look me back to unpleasant but familiar feeling i though i would left behind year ago.

She wrote.

Here i was sitting alone one night after getting my daughter to bed. thinking May be i m not cool enough. All of sudden i was in high school again.

Tisdale believed she had found her village. she wrote. At some point she start to wonder whether that was really true.

A NASA spacecraft orbiting Mars may be dead

Posted on by

NASA lost communication with its MAVEN probe almost a month before and attempt to re establish a connection have been futile.

For nearly a month NASA has been scrambling to make contact with spacecraft in orbit around Mars that fell silent.

The space agency lost communication with MAVEN probe on Dec. 6 and attempt to re establish a connection have been futile.

The ALMA Array is completed with 145 New Low Noise Amplifiers

Based on bits of data received that day mission controllers think the probe was spinning unexpectedly.

MAVEN spacecraft entered orbit around Mars in 2014 it has been studying the red planet upper atmosphere including plasma layer famous as ionoshphere and investigating how and why Mars has been losing its atmosphere over billion of years.

The spacecraft has been instrumental in relaying communication between two rovers on surface of Mars, curiosity and perservance and earth.

NASA has not able to reach MAVEN since it experience what agency called a loss of signal with ground station on Earth on Dec 6.

At time the spacecraft was orbiting behind Mars so signal loss was routine.

Mars always blocks Maven from phoning home during maneuver.

Probe re emerged from behind red planet NASA could not pick up any signals from it.

Nasa added it was investigating the anomaly in statement on Dec. 9 but provided few details.

Mission controllers reported that all of Maven subsystem had been working normally before it passed behind Mars.

The Maven mission was designed to last two years but it has been operating continously for over a decade.

NASA celebrated the probe 10th anniversary orbiting Mars.

The process of atmospheric loss on Mars MAVEN was helping scientist to get clearer picture of planet past and present climate and how it transformed from potential habitable world with liquid water on its surface to cold and barren planet that is today.

The spacecraft is one of three NASA currently has in orbit around Mars.

The space agency also operated the Mars Orbiter which launched in 2005 and Mars Odyseey which lifted off in 2001.

Web Telescope Spots “Impossible” Atmosphere Around Ancient Super Earth

Posted on by

JWST observations of the ultra hot super Earth exoplanet TOI-561 provide the evidence to date for atmosphere surrounding rocky planet beyond our solar system.

A team of astronomer led by Carnegie researchers has uncovered the clearest evidence so far a rocky planet outside our  Solar System possesses an atmosphere.

The findings reported in The Astrophysical Journal Letters are based on observations from NASA James Webb Space Telescope JWST.

The data indicates the presence of atmosphere on unlikely world an ancient extreme hot super Earth that is thought to be covered by global ocean of molten rock.

Canada Web Space News

Galaxy

The planet called TOI-561 b is twice as massive as Earth but is otherwise very different from our planet.

Its extreme conditions are driven by its tight orbit around its star.

The star itself is smaller and cooler than the Sun, TOI-561 b circles it one fortieth the distance between Sun and Mercury.

This close orbit the planet completed a full year in only 10.56 hours and one hemisphere is exposed to starlight.

Astronomers would have predicted that planet like this is too small and hot to retain its own atmosphere for long after formation explained Carnegie Science Postdoctoral Fellow Nicole Wallack the paper second author.

Our observations suggest it is surrounded by relative thick blanket of gas spending conventional wisdom about ultra short period planets.

JWST observations

These are first results from JWST General Observers Program 3860 which involved observing the system continuously for over 37 hours while TOI-561 b completed almost for full orbits of the star.

The team is analyzing the full data set to map the temperature all the method around the planet and narrow down  the composition of atmosphere.

Teske and Wallack leadership on this JWST paper present a tradition of Carnegie Science excellence dating back to mission conception three decades before and extending through first four cycles of  time allocation on revolutionary space telescope.

JWST finished calibrations and start collecting data for astronomical research programs, Teske, Wallack and other Carnegie Earth and Planets Laboratory and Observatories  affiliated scientists have led over dozen JWST teams and announced groundbreaking results about exoplanet atmospheres  galaxy formation.

These JWST powered breakthroughs tap directly into our long standing strength in how exoplanet characters are shaped by planetary evolution and dynamics.

There are more results on horizon and we are poised for new wave of Carnegie led JWST science in year ahead.

Challenging Planetary Expectations

In our own solar system planets that are small and intense heated were unable to keep the original gaseous envelops they acquired in their histories.

TOI-561 b appears to have held on its atmosphere even though it orbits a star that is older than the sun.

This lingering atmosphere may account for other puzzle the planets surprisingly low density.

TOI-561 b is lighter than scientist would expect based on size alone and presence of atmosphere could help explain why.

It is not what we call a super puff or cotton candy planet but it is less dense than you would expect if it had earth like composition.

In designing the observing program the team considered that planet low density could be explained by relative small iron core and mantle made of rock is less dense than rocks that comprise Earth interior.

Teske points that this could make sense TOI-561 b is distinct among ultra short period planets in that it orbits a old twice as old as Sun iron poor star in a region of Milky Way famous as thick disk.

It must have shaped in different chemical environment from planets in our own Solar System.

This mean that composition could be representative of planets that formed when universe was relatively young.

Searching for Atmosphere

In deciding to study TOI-561 b the research team suspect that it might be surrounded by thick atmosphere that makes it look larger and thus less dense.

To test existence of TOI-561 b atmosphere the astronomer used JWSY Near Infrared Spectrograph NIRSpec instrument to measure the planet dayside temperature based on brightness in near infrared.

The technique which consist of measuring the decrease in brightness of star planet system as the planet moves behind the star is similar to search for atmospheres in the TRAPPIST-1 system and other rocky worlds.

Using Webb, Canadian Astronomers explains the Milky Way Turbulent Past

Posted on by

The Milky Way has long and fascinating history that extends back to early Universe ca 13.61 billion years before.

It has evolve and merged with other galaxies to become the galaxy we see today.

In latest study a team of Canadian astronomers has created the detailed reconstruction of how the Milky Way evolved from its earliest phase to current phase.

Using data provided by the James Webb Space Telescope JWST the team examined 877 galaxies whose masses properties closely match what astronomers expect the Milky Way looked like over time.

James Webb Telescope

Astrophysics

The galaxies in this survey spanned range of cosmic time from when the Universe was1.5 to 10 billion years old.

By observing more galaxies that existed when the Universe was younger the team created a visual timeline of Milky Way evolution.

To their surprise they found that Milky Way had remarkably turbulent youth before setting into stable and structure adult we are familiar with today.

In accordance with the Hubble Sequence astronomers classify galaxies into three groups based on their shapes spiral, elliptical and barred spiral.

Elliptical galaxies represent early phase of evolution and have structure or interstellar dust and gas.

Lenticulars which represent intermediate phase in evolution consist of bright central bulge surrounded by extended disk, spiral noted for their pinwheel form,  consist of central bulge and flattened disk with stars shaping spiral structure.

Outside of these three morphologies are famous as irregular galaxies.

The study was led by Dr Vivian Tan who completed her PhD at York University under supervision of Prof. Adam Muzzin.

James Webb Telescope

Astrophysics

They were joined by researchers from Dunlap Institute of Astronomy and Astrophysics, the SMU Institute for Computational Astrophysics, the Kapteyn Astronomical Institute, the Columbia Astrophysics Laboratory, the Space Telescope Science Institute.

The galaxies in sample are dated to crucial epoch when galaxies went from being smaller, masses of stars to stable disk galaxies that are common today.

For their study, the team combined high resolution imaging from the JWST and venerable Hubble to create census of 877 early galaxies.

The JWST observation were obtained as part of the Canadian NIRISS Unbiased Cluster Survey CANUCS.

This Canadian observing program uses data from Webb Near Infrared Imager and Slitless Spectrograph NIRISS.

This instrument was built by Canadian Space Agency CSA in partnership with the Universite de Montreal the National Research Council Herzberg Centre for Astronomy and Astrophysics, and Honeywell Robotics, CANUCS uses data from the NIRISS instrument to observe five galaxy clusters which are natural gravitational lenses that allow astronomers to observe fainter more galaxies.

Mixed with visible light observations by Hubble the team created resolved stellar mass and star formation SFR maps for each galaxy observed.

These maps showed where existing stars were located.

New stars were forming during different phases of galaxies evolution.

The results showed a clear pattern across entire sample showing that Milky Way Galaxy twins grew from the inside out between 3 and 4 billion years after Big Bang.

Galaxy

They start with dense central region and mass in their outer regions through mergers and new star formation gradually forming extended spiral structures.

Tan and her colleagues then ran state of the art computer simulations that track the evolution of Milky Way like galaxies which confirmed inside out growth model they observed.

The simulation failed to reproduce the high central nature of early galaxies in some cases and failed to predict how mass accumulated in outer regions.

These results provide constrains for theoretical models of evolution and mechanism involved including feedback merger rates.

Astronomers have been modeling the formation of the Milky Way and spiral galaxies for decades said Tan.

It is amazing that with the JWST we can test their models and map out how Milky Way progenitors grow with Universe itself.

A major takeaway from this study is pointed that Milky Way early history was more chaotic than previously expected.

It appear galaxies in early time were constantly celliding and  accreting material triggering intense bursts so star formation.

This is evidence by highly disturbed shapes and asymmetric features they observed.

Milky Way twins appear much more stable in later cosmological times characterized by smoother structures and more distributed star formation.

Hubble partial view Galactic Gas Making a Getaway

A sideways spiral galaxy shines in this NASA/ESA Hubble Space Telescope photos.

Located about 60 million light years away in constellation virgo.

NGC 4388 is resident of the Virgo galaxy cluster.

This huge cluster of galaxies consist of more than a thousand members and is nearest large galaxy cluster to the Milky Way.

NGC 4388 appears to tilt at extreme angle relative to our point of view giving us a near edge on prospect of galaxy.

This perspective reveals a curious feature this was not visible in Hubble image of this galaxy released in 2016 a plume of gas from galaxy nucleus here seen billowing out from galaxy disk toward lower right corner of the photos.

Hubble Telescope

Nasa images

The answer lies in vast stretches of space that separate the galaxies of the Virgo cluster.

The space between galaxies appears empty the space is occupied by hot wisps of gas called the intracluster medium.

As NGC 4388 moves within Virgo cluster it moves through the intracluster medium.

Pressure from hot intracluster gas whisks away gas from within NGC 4388 disk causing it to trail behind as NGC 4388 moves.

The source of ionizing energy that causes this gas cloud to glow is more uncertain.

Researchers suspect that some of energy comes from center of the galaxy where supermassive black hole spin gas around it into superheated disk.

The blazing radiation from disk might ionize the gas closest to galaxy while shock waves might responsible for ionizing filaments of gas farther out.

 

NASA Webb Telescope just discovered one of the fantastic planets ever

The latest observe world has stretched lemon like shape and may even consist of diamonds deep inside.

It is strange character make it difficult to classify sitting somewhere between what astronomers consider a planet and star.

A Carbon World Unlike Any Other

The object officially named PSR J2322-2650b has atmosphere dominated by helium and carbon rather than familiar gases seen on most known exoplanets.

With mass comparable to jupiter,  the planet is shrouded in dark soot like clouds.

Inside the planet scientists believe carbon from these clouds could be compressed into diamonds.

The planet circles a spinning neutron star.

The planet orbits a star that is completely difficult the mass of the sun but size of city said university of Chicago astrophysicist Michael Zhang the study principal investigator.

The sticky problem of Lunar Dust Get a mathematical solution

Posted on by

Apollo astronauts discovered unexpected enemy on the Moon.

Fine dust, start by their movements and attracted by static electricity coated everything.

It found its way through seals, scratched visors and clung to suits despite brushing.

Eugene Cernan described it one of most aggravating aspects of lunar operations.

Over five decades later humanity prepares to return to the Moon with sophisticated equipment solving the lunar dust problem has become critical.

Lunar Rover

Appolo

Researchers from the Beijing Institute of Technology, China Academy of Space Technology and Chinese Academy of Sciences have developed a detail theoretical model that explain how charged dust particles interact with spacecraft surfaces during low velocity collisions.

The challenge starts with Moon harsh environment.

On the dayside intense solar ultraviolet and X ray radiation strips electrons from both spacecraft and lunar surface leaving them positively charged.

This creates photoelectron sheath hovering above ground.

On the nightside spacecraft and regolith instead collect electrons from surrounding plasma becoming negative charged and forming what is called a Debye sheath.

The solar wind adds other layer of complexity continuously bathing in charged particles.

Within this electrically active environment dust particles themselves become charged and experience three distinct electrostatic forces as they approach a spacecraft.

Lunar Rover

Appolo

The electric field force acts on particle surface charge pulling it toward or pushing it away from vehicle depending on whether their charges are  opposite or the same.

The dielectrophoretic forces arises because the dust particle distort the non uniform electric field around it creating attraction toward regions of stronger field regardless of particle charge.

The image force emerges when the approaching charged particle creates opposite charge in spacecraft conductive surface similar to how balloon sticks to wall creating additional attractive pull.

The researches model treats these electrostatic interactions in mathematical detail but recognizes that other forces dominate once contact starts.

When dust grain actually strikes a spacecraft coating adhesive van der Waals forces between molecules at surface become dominant for the slow velocity impacts common during lunar operations.

The collision itself unfolds in three stages. First comes adhesive elastic loading, where the particle compresses against the coating while attractive forces between surfaces grow.

Lunar Rover

Appolo

If impact is energetic enough the coating starts to deform, dissipating energy as material yields.

During unloading stage the particle either bounces away or remains stuck depending on whether the collision velocity falls within critical range.

The model announces several practical.

A dielectric coating with high thickness and low permittivity can reduce the electrostatic attraction between charged dust and spacecraft.

The particle surface charge density matter over spacecraft electrical potential in determining strength of electrostatic forces.

For particles carrying typical charge densities below o.1 milliColumbs per square meter.

The adhesive Van der Waals force overwhelms electrostatic effects during actual contact.

Most useful for mission planners the research shows that coating made from low surface energy material with rough textures can reduce dust adhesion.

Larger particles tend to have higher coefficients of restitution meaning they are more likely to bounce away rather than stick.

There exist a critical velocity range for negative charge particles where adhesion occurs. impacts slower or faster than this window permit particles to escape.

This latest mode can predict dust accumulation pattern guide selection of surface coating and help optimize dust removal systems.

Mission to moon grow more ambitious and long duration solving sticky problem of lunar dust moves from annoyance to operational necessity.

The ALMA Array is completed with 145 New Low Noise Amplifiers

Posted on by

For decades scientists have observed the cosmos with radio antennas to visualize the dark distant regions of the Universe.

This consist of the gas and dust of the interstellar medium ISM planet forming disks and objects that cannot be observed in visible light.

In this field the Atacama Large Millimeter/Submillimeter Array ALMA in Chile stands out as one of world powerful radio telescopes.

Using its 66 parabolic antennas, ALMA observes the millimeter and submillimeter radiation emitted by  cold molecular clouds from which new stars are born.

Each antenna is equipped with high frequency receivers for ten wavelength ranges 35-50 GHZ and 787-950 GHZ known as Band 1.

The ALMA Array is completed with 145 New Low Noise Amplifiers

Thanks to Fraunhofer Institute for Applied Solid State Physics IAF and the Max Planck Institute for Radio Astronomy MPIFR, ALMA has received upgrade with addition of 145 new low noise amplifiers LNAs.

These amplifiers are part of facilities Band 2 coverage ranging from 67 to 116 GHz on the electromagnetic spectrum.

This coverage will allow researchers to study and gain better understanding of Universe.

They hope to gain new insights into cold interstellar medium the dust, gas radiation and magnetic fields from which stars are born.

Scientist will be able to study planet forming disk in better detail.

But certainly not least they will be able to study complex organic molecules COM in nearby galaxies which considered precursors to building blocks of life DNA, RNA.

These studies will allow astronomers and cosmologists to witness how stars and planetary systems form and evolve and how presence of organic molecules can lead to emergence of life.

Each LNA consist of a series of monolithic microwave integrated circuits MMICs developed by Frauhofer IAF using the semiconducting material indium gallium arsenide INGAAS.

The ALMA Array is completed with 145 New Low Noise Amplifiers

MMICs are based on metamorphic high electron mobility transistor mHEMT technologt a method for creating advance transistors that are flexible and allow for performance in high frequency receivers.

The addition of LNAs equipped with these circuits will amplify low noise signals and minimize background noisce increasing the sensitivity of ALMAs receivers.

Frauhofer IAF and MPIFR were commissioned by the European Southern Observatory ESO to provide amplifiers.

Frauhofer IAF was responsible for designing, testing and manufacturing the MMICs at room temperature, MPIFR was task with assembling and qualifying the LNA modules, then testing them in cryogenic conditions.

This is wonderful recognition of our fantastic collaboration with Fraunhofer IAF which shows that amplifiers are not only made in Germany but best in world said Prof Dr. Michael Kramer executive director at MPIFR.

Dr Fabian Thome head of subproject at Frauhofer IAF explained in IAF press release.

The performance of receivers depend on the performance of the first high frequency amplifiers installed in them.

Our technology is characterized by an average noise temperature of 22 K which is unmatched worldwide.

The ALMA Array is completed with 145 New Low Noise Amplifiers

New LNA signals can be amplified more than 300 fold in first step.

This enables the ALMA receivers to measure millimeter and submillimeter radiation from depths of universe much more precisely and obtain better data.

We are proud that our LNA technology is helping us to better understand the origin of stars and entire galaxies.

A Saturn Sized Planet is Drifting Through Space Alone

Posted on by

Astronomers have weighed a wandering rogue planet uncovering a Saturn mass world flung into galaxy after dramatic planetary breakup.

A latest study reports that astronomers have measured both mass and distance of new found free floating planet by observing it at the same time from Earth and from space.

This rare combination of viewpoints made it possible to pin down details that usually remain out of reach.

The results shed light on many ways planets can be expelled from home systems and sent drifting through interstellar space.

Only small number of free floating planets have been identified so far researchers expect discoveries to accelerate in near future specially with NASA Nancy Grace Roman Space Telescope campaign schedule to launch in 2027.

Rogue Planets and a Subtle Signal

Most planet orbit one or more stars but growing evidence shows that some worlds travel through galaxy alone.

These solitary objects famous as free floating or rogue planets have no known stellar partner.

They give off very little light astronomers usually detect them only when their gravity bend and amplifies the light of distant background star.

This effect is called microlensing.

A major drawback of microlensing is that if typically does not reveal how far away from planet is which makes it difficult to decide its mass on its own.

Many properties of these wandering planets have remained uncertain.

A Rare Earth and Space Collaboration

In latest research Subo Dong and colleagues describe the discovery of free floating planet spotted during short lived microlensing event,

This case apart was that event was observe from Earth and from space.

The team combined data from several ground based surveys with observations from Gala Space telescope.

Small differences in timing of light signal reaching these widely separated locations allowed the scientist to calculate the microlensing parallax.

This measurement was paired with finite source point lens modeling the researchers were able to decide both planet mass and position in galaxy.

The planet is about 22 percent the mass of Jupiter and located almost 3000 parsecs from center of Milky Way.

With mass similar to Saturn the researchers argue that it most formed as part of planetary system rather than developing on its own like small star or brown dwarf.

Scientist think that low mass rogue planet like this one are born around stars and later thrown out of original orbits by gravitational disturbances like close encounters with other planets.
