At the heart of most massive galaxies in our Universe, there are supermassive black holes (SMBH) that are on the order of millions to billions of times the mass of the Sun. As these behemoths slowly consume gas and dust that is slowly fed into their maws, they release tremendous amounts of energy. This leads to what is known as an Active Galactic Nucleus (AGN) – aka. a quasar – which can sometimes send hypervelocity jets of material for light-years.

The Best Evidence for Life on Mars Might be Found on its Moons
The search for Martian life has been ongoing for decades. Various landers and rovers have searched for biosignatures or other hints that life existed either currently or in the past on the Red Planet. But so far, results have been inconclusive. That might be about to change, though, with a slew of missions planned to collect even more samples for testing. Mars itself isn’t the only place they are looking, though. Some scientists think the best place to find evidence of life is one of Mars’ moons.
