Artist's rendering of the accretion disc in ULAS J1120+0641, a very distant quasar containing a supermassive black hole with a mass two billion times that of the Sun [1] The Chandra X-ray image is of the quasar PKS 1127-145, a highly luminous source of X-rays and visible light about 10 billion light-years from Earth. An enormous X-ray jet ...
This list contains natural objects up to apparent magnitude 3.5. All objects are listed by their visual magnitudes, and objects too close together to be distinguished are listed jointly. Objects are listed by their proper names or their most commonly used stellar designation. This list does not include transient objects such as comets, or ...
It was first detected on June 14, 2015, located within a faint galaxy in the southern constellation Indus, and was the most luminous supernova-like object ever observed. [4] At its peak, ASASSN-15lh was 570 billion times brighter than the Sun, and 20 times brighter than the combined light emitted by the Milky Way Galaxy . [ 4 ]
All Wolf–Rayet stars are highly luminous objects due to their high temperatures—thousands of times the bolometric luminosity of the Sun (L ☉) for the CSPNe, hundreds of thousands L ☉ for the population I WR stars, to over a million L ☉ for the WNh stars—although not exceptionally bright visually since most of their radiation output ...
Lying at a distance of 9.5 billion light years away, the CCLQG is a cosmic decoupling of 34 individual quasars (highly luminous active galactic nuclei powered by supermassive black holes) spanning a region roughly 2 billion light-years in length, and about 1 billion light years wide, making it one of the largest and most exotic cosmic structures known in the observable universe.

Therefore, its future evolution is highly uncertain, but almost certainly involves further mass loss and an eventual supernova. [119] η Carinae A would have begun life as an extremely hot star on the main sequence, already a highly luminous object over a million L ☉.
The Cosmic Cliffs at the edge of NGC 3324, one of the first images taken by the James Webb Space Telescope. The Carina Nebula [7] or Eta Carinae Nebula [8] (catalogued as NGC 3372; also known as the Great Carina Nebula [9]) is a large, complex area of bright and dark nebulosity in the constellation Carina, located in the Carina–Sagittarius Arm of the Milky Way galaxy.
