Using the South Pole Telescope, astronomers have detected powerful stellar flares erupting from stars near the supermassive black hole at the centre of the Milky Way. Operating at millimetre wavelengths that can penetrate the dust obscuring our view of the core of the Galaxy, the telescope caught these dramatic magnetic energy releases in one of the most extreme environments in our Galaxy. The discovery opens a new observational window for studying stellar behaviour in regions previously hidden from view and provides insights into how stars survive and behave in the intense gravitational and radiation environment surrounding the Milky Way's central black hole.

Supermassive black holes grow larger by accreting matter. When they're actively accreting matter they're called active galactic nuclei (AGN). AGN are the most luminous sources of persistent radiation in the Universe, yet they turn on and off as the SMBH passes through quiet and active phases. Astronomers have found one that is just turning on its powerful jets after a long period of dormancy.

An international team of astronomers has uncovered the first definitive evidence that at least some fast radio bursts (FRBs) originate in binary stellar systems.

It's 2041 and an astronaut on Mars Station 1 orbiting the Red Planet is inspecting life support systems in the bowels of the habitat. They open a compartment and are aghast to discover a mysterious goop clinging to the walls in microgravity that definitely shouldn't be there. In their shock, they immediately have flashbacks from every alien-based science fiction movie they've ever seen, and are convinced they not only just discovered the first signs of alien life, but they won't live to tell about it. After telling the rest of the crew in a heated panic, they calmly explain it's not an alien menace, but a substance called biofilm, which has been present on Earth for billions of years.

BepiColombo is slowly uncovering more and more fun facts about Mercury as it continues its preliminary mission. One of the more interesting things found so far is a magnetic “chorus” that appears similar to a phenomenon found in Earth’s much larger magnetic field. A new paper in Nature Communications from the researchers responsible for the probe’s Mio instrument that is studying Mercury’s magnetic field describes what could be thought of as a form of magnetic birdsong.

Jupiter’s atmosphere and clouds have mesmerized stargazers for centuries, as their multi-colored, swirling layers can easily be viewed from powerful telescopes on Earth. However, NASA’s Juno spacecraft has upped the ante regarding our understanding of Jupiter’s atmospheric features, having revealed them in breathtaking detail. This includes images of massive lightning storms, clouds swallowing clouds, polar vortices, and powerful jet streams. Yet, despite its beauty and wonder, scientists are still puzzled about the processes occurring deep inside Jupiter’s atmosphere that result in these incredible features.

There's a lot going on here.

It won't be the last.

Here's what the research shows.

The taboo lead single from their 1991 album became an international hit. Continue reading…
