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.

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.
