| SN2014J | - Type Ia supernova - one of the closest supernovas discovered in decades - in M82 galaxy - discovered January 21, 2014 |
| NGC 4993 | - contains a gravitational wave event called GW170817 - aftermath of gravitational waves also emit X-Rays - gives strong evidence of being a short gamma-ray burst kilonova (occurs after two neutron stars merge) |
| 47 Tucanae/X9 | - a dense cluster of stars on the edge of the Milky Way - the closest orbit between a star and a black hole - binary: X9 a white dwarf and a stellar mass black hole |
| Sagittarius A* | - located in the middle of the Milky Way galaxy |
| Abell 400 | - a galaxy cluster - shows radio jets immersed in a vast cloud of multi million degree X-ray emitting gas - jets emanate from two supermassive black holes - black holes in dumbbell galaxy NGC 1128 |
| Chandra Deep Field South | - contains the highest concentration of black holes ever seen - deepest X-ray image ever - gives a look at the growth of black holes |
| Antennae Galaxies | - starburst galaxy - two spiral galaxies merging together - super star clusters: brightest and most compact of these star birth regions - lots of supernovas |
| M51/NGC 5195 | - one of the nearest supermassive black holes - contains a large spiral galaxy NGC 5194 (Whirpool galaxy) mergind with smaller companion NGC 5195 |
