Researchers have found evidence of a cataclysmic flare that punched outward in both directions from our galaxy’s center, reaching so far into intergalactic space that its impact was felt 200,000 light-years away.

The violent history of Andromeda, the big galaxy next door
“The Milky Way is on a collision course with Andromeda in about 4 billion years. So knowing what kind of a monster our galaxy is up against is useful in finding out the Milky Way’s ultimate fate.” Source: https://earthsky.org/space/andromeda-galaxy-history-milky-way-collision…
Aliens May Have Bugged Co-Orbital Space Rocks To Spy On Earth, Scientist Says
dryriver shared this article from NBC News’ science blog Mach: Picture this: A hundred million years ago, an advanced civilization detects strange signatures of life on a blue-green planet not so far away from their home in the Milky Way. They try sending signals, but whatever’s marching around on that unknown world isn’t responding. So, the curious galactic explorers try something…
The mass inflow and outflow rates of the Milky Way
According to the most widely accepted cosmological models, the first galaxies began to form between 13 and 14 billion years ago. Over the course of the next billion years, the cosmic structures now observed first emerged. These include things like galaxy clusters, superclusters and filaments, but also galactic features like globular clusters, galactic bulges, and supermassive black holes (SMBHs).

Astronomers identify four globular cluster planetary nebulae candidates
Astronomers from Chile and Argentina report the detection of four new planetary nebulae (PN) candidates residing in galactic globular clusters (GCs). If confirmed, the discovery would double the number of known PNe in galactic GCs. The finding is presented in a paper published September 19 on the arXiv pre-print server.

Milky Way’s black hole appears to be getting hungrier
“We have never seen anything like this in the 24 years we have studied the supermassive black hole. It’s usually a pretty quiet, wimpy black hole on a diet. We don’t know what is driving this big feast.” Source: https://earthsky.org/space/milky-ways-black-hole-appears-to-be-getting-hungrier…
