The term "black hole" was used in print by Life and Science News magazines in 1963, [60] and by science journalist Ann Ewing in her article " 'Black Holes' in Space", dated 18 January 1964, which was a report on a meeting of the American Association for the Advancement of Science held in Cleveland, Ohio.

The universe contains pulsars, black holes, and brown dwarfs, barely lit up by white dwarfs. Over time, gravity ejects most cosmic remnants into the freezing interstellar space. Notably, neutron stars may collide and make superluminous supernovae. Extraterrestrial life might live around aging white dwarfs, which someday die and become black dwarfs.
A black star with a radius slightly greater than the predicted event horizon for an equivalent-mass black hole will appear very dark, because almost all light produced will be drawn back to the star, and any escaping light will be severely gravitationally redshifted. It will appear almost exactly like a black hole.

[1] Transitions provide greater cohesion by making it more explicit or signaling how ideas relate to one another. [1] Transitions are, in fact, "bridges" that "carry a reader from section to section". [1]
The episode presented an in-depth treatment of black holes, beginning with John Michell's suggestion of the existence of an "invisible star" to the first discovery of a black hole, Cygnus X-1. [2] The episode's title is an allusion to how light from stars and other cosmic objects takes eons to travel to Earth, giving rise to the possibility ...

Little red dots (LRDs) are a class of small, red-tinted galaxies discovered by the James Webb Space Telescope. [1] [2] [3] Their discovery was published in March 2024, and they are currently poorly understood. [4] They appear to have existed between 0.6 and 1.6 billion years after the Big Bang, from 13.2 to 12.2 billion years ago. [1]
