Giant radiation bubbles created by monster black hole feeding frenzy, new study suggests

Two giant bubbles of gamma rays and X-rays that erupted from the center of the Milky Way may stem from a supermassive black hole‘s feeding frenzy at the heart of the galaxy, a new study finds. Recently, the X-ray telescope eROSITA onboard the Spektr-RG space observatory discovered a pair of gigantic X-ray-emitting bubbles, each about … Read more

Giant Bubbles Expanding From The Milky Way Could Be Explained by a Single Event

Two sets of giant bubbles that extend thousands of light-years above and below the plane of the Milky Way could have been produced by the same event, in spite of their significant difference in size. ¬† They’re called the Fermi bubbles and the eROSITA bubbles, and astronomers believe they were the result of activity by … Read more

Physicists Just Smashed a Record by Keeping a Bubble Intact For Over a Year

When you think of the word “ephemeral”, many people will immediately conjure up the image of a soap bubble: delicate, gorgeous, and gone in a blink (or maybe a few). Now a team of physicists led by Aymeric Roux of the University of Lille in France has defied this clich√©, creating a bubble that maintained … Read more
