by

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 cliché, creating a bubble that maintained … Read more
