On a clear night, it’s possible to see our entire galactic neighborhood from Earth. You need the right conditions: very little light (which is why so few stars are visible in cities), and it’s ideal to be high up, so that there’s not much atmosphere getting in the way of your view. Recently,...

The Event Horizon Collaboration, the group behind the first-ever image of a black hole, just achieved another huge accomplishment: an image of Sagittarius A*, the black hole at the center of the Milky Way. This is a breakthrough in our understanding of our home galaxy and the astrophysics of its...

Through a standard telescope, the nearby galaxy NGC 7727 looks like a gossamer tumbleweed drifting in the night sky. But within it are two supermassive black holes locked in a dance that will end with their violent merger. As a team of astronomers recently found, these objects are closer to Earth...

During its third flyby of Venus, NASA’s Parker Solar Probe recorded natural radio emissions from within the Venusian atmosphere. The finding is confirmation that Venus’s upper atmosphere undergoes major changes in accordance with the Sun’s 11-year cycle, providing new insights into this...

Some 230 million light-years from Earth, there’s a black hole going places. These extraordinarily dense objects are usually found sitting at the center of a galaxy violently gobbling up matter, so it was a surprise when astronomers spotted this one moving out of step with its resident galaxy.Read...
