This is a list of hottest stars so far discovered (excluding degenerate stars), arranged by decreasing temperature. The stars with temperatures higher than 60,000 K are included. List
This is a list of the hottest exoplanets so far discovered, specifically those with temperatures greater than 2,500 K (2,230 °C; 4,040 °F) for exoplanets irradiated by a nearby star and greater than 2,000 K (1,730 °C; 3,140 °F) for self-luminous exoplanets.
In this map of the Observable Universe, objects appear enlarged to show their shape. From left to right celestial bodies are arranged according to their proximity to the Earth. This horizontal (distance to Earth) scale is logarithmic.
A hot, dust-obscured galaxy, or hot DOG, is a rare type of quasar. [ 1 ] [ 2 ] [ 3 ] The central black hole of such a galaxy emits vast amounts of radiation which heats the infalling dust and gas, releasing infrared light at a rate about 1,000 times as much as the Milky Way , making these some of the most luminous galaxies in the universe.

A star is a massive luminous spheroid astronomical object made of plasma that is held together by its own gravity.Stars exhibit great diversity in their properties (such as mass, volume, velocity, stage in stellar evolution, and distance from Earth) and some of the outliers are so disproportionate in comparison with the general population that they are considered extreme.
To help try to put that into perspective, here are 10 of the biggest things of the universe in order of smallest to largest: 10. Ceres -- The biggest asteroid ever discovered by humans was found ...
The highest-redshift quasar known (as of August 2024) is UHZ1, with a redshift of approximately 10.1, [48] which corresponds to a comoving distance of approximately 31.7 billion light-years from Earth (these distances are much larger than the distance light could travel in the universe's 13.8-billion-year history because the universe is expanding).
WR 102 was first mentioned as the possible optical counterpart to a peculiar X-ray source GX 3+1. [6] However, it became clear that it was a separate object and in 1971 it was highlighted as a luminous star with unusual O VI emission lines in its spectrum. [7]
