Supermassive black hole creates massive bubbles at center of Milky Way
Since 2020, when the X-ray telescope eRosita took images of the bubbles, astronomers have debated their origin.
The new study also shows the jet began...
Moon’s orbit could be a natural gravitational wave detector
Gravitational waves, predicted by Albert Einstein at the start of the 20th century and detected for the first time in 2015, are the new...
