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.
This is a list of coolest stars and brown dwarfs discovered, arranged by decreasing temperature. The stars with temperatures lower than 2,000 K are included. Kirkpatrick et al. 2021 [ 1 ] has a more complete list of nearby objects with a temperature below 2,400 K. Objects with a temperature below 500 K from this paper were included in this list.
The universe was only 630 million years old when the GRB occurred, and its detection confirms that massive stars were born and dying even very early on in the life of the universe. GRB 090423 and similar events provide a unique means of studying the early universe, as few other objects of that era are bright enough to be seen with today's ...
The gamma-ray burst GRB 971214 measured in 1998 was at the time thought to be the most energetic event in the observable universe, with the equivalent energy of several hundred supernovae. Later studies pointed out that the energy was probably the energy of one supernova which had been "beamed" towards Earth by the geometry of a relativistic jet.

This is a list of the coolest exoplanets known, specifically those with temperatures lower than −75 °C (198 K). Planets from the Solar System were also included for comparison purposes. Discovered in 2006, OGLE-2005-BLG-390Lb is the coldest known exoplanet, and was nicknamed " Hoth " by NASA in reference to the planet from the Star Wars ...
