Analysis of a rare flare at a redshift of z = 0.092 — captured by chance by the XMM–Newton spacecraft — suggests that it may be interpreted as a supernova shock break-out or an early cocoon.

The disks of four jellyfish galaxies being tidally stripped of their gas by the intergalactic medium show molecular gas contents 4–5 times higher than normal galaxies of similar masses and very low star-formation efficiency.
