…while light cannot escape a black hole, its extreme gravity warps space around it, which allows light to “echo,” bending around the back of the object. Thanks to this strange phenomenon, astronomers have, for the first time, observed the light from behind a black hole.
As a kid I remember reading about “Vulcan,” which people used to think existed between Mercury and the Sun but always orbited on the opposite side.
Completely fictional, of course.
Vulcan made a comeback as the fictional home of Spock in Star Trek. It was said by Star Trek creator Gene Roddenberry to be orbiting around 40 Eridani (also called HD 26965), a triple star system in the constellation of Eridanus “the river” in the southern hemisphere just 16 light years distant. In September 2018, astronomers at the University of Florida in Gainesville found a “super-Earth” exoplanet orbiting exactly where Vulcan was said to be.
