Jaws dropped when alien-like creatures were presented to Mexico's congress by a self-proclaimed UFO expert as proof that aliens visited Earth. Supposedly, they were found in Peru in 2017. Now, the presentation is being met with international ridicule. Meanwhile, NASA held a news conference saying, after decades of speculation, its 16-member panel of experts concluded it did not find any evidence of extraterrestrial life.

A new model is bringing scientists a step closer to understanding the kinds of light signals produced when two supermassive black holes, which are millions to billions of times the mass of the Sun, spiral toward a collision. For the first time, a new computer simulation that fully incorporates the physical effects of Einstein's general theory of relativity shows that gas in such systems will glow predominantly in ultraviolet and X-ray light

This artist’s rendering illustrates new findings about a star shredded by a black hole. When a star wanders too close to a black hole, intense tidal forces rip the star apart.

For the first time, NASA’s planet-hunting Transiting Exoplanet Survey Satellite (TESS) watched a black hole tear apart a star from start to finish, a cataclysmic phenomenon called a tidal disruption event.
