Now they tell us. 

After 20 years of watching Sagittarius A*, the black hole at the center of our galaxy (that's right, no matter what astrology sign you pretend to be, we're all Sagittarius), in May astronomers saw something they'd never seen before.

Using the Keck Telescope at Mauna Kea in Hawaii (because it's 13,00 feet in the air, above 40 percent of the earth's atmosphere, it is great for infrared - this was before 2015 when mainland activists invaded to declare science was ruining a "sacred" place) they found the infrared imaging was much brighter

But don't let the doomsday crowd scare you. We can talk about this month or last but Sgr A* is almost 26,000 light years away, so if aliens are messing around we have a long time to prepare, unless they have found a way to manipulate the multiverse or the quantum realm or whatever magic that Marvel movies and Medium bloggers are writing now.
