Stephen Hawking was the first to propose that not everything that comes in contact with a black hole succumbs to its immense gravity and inevitable nothingness. In fact, tiny particles of light, known as photons, are sometimes ejected back out of the black hole, robbing it of energy. This gradual loss of mass over time means that every black hole eventually evaporates out of existence.
These galaxies lie a mere 250 million light-years away—and they will only get closer, because they appear to be pulling us towards them at breakneck speed.

Bearing the slightly wordy name of GJ 1132b, the new neighbour is a rocky, Earth-sized planet that's located only 39 light-years away from us in the Vela constellation, which is visible from the southern hemisphere.
The brightest galaxies in our universe are fuelled by what their gravity sucks in, not through explosive mergers of star systems as scientists previously argued, researchers said Wednesday.
In what may be the most complete explanation yet of how these enormous collections of stars and dust came to be, scientists found the galaxies pulled in hydrogen gas and then used it to pump out the equivalent of up to 2,000 Suns per year, according to a study in Nature.
