The Surprising Heat of Early Clusters January 14, 2026
Astronomers using ALMA have detected the earliest hot galaxy cluster atmosphere ever observed, revealing a massive reservoir of superheated gas in the infant cluster SPT2349-56 just 1.4 billion years after the Big Bang. The gas is far hotter and more pressurised than current theories predicted for such a young system, forcing scientists to completely rethink […]
How Black Holes Slowly Starve Galaxies January 14, 2026
Astronomers using the James Webb Space Telescope and ALMA have discovered one of the oldest ‘dead’ galaxies in the universe, revealing that supermassive black holes can kill galaxies through slow starvation rather than violent destruction. The galaxy, nicknamed ‘Pablo’s Galaxy’, formed most of its 200 billion solar masses of stars between 12.5 and 11.5 billion […]
When Baby Stars Throw Tantrums January 13, 2026
NASA’s Hubble Space Telescope has captured stunning new image of HH 80/81, a pair of objects created when supersonic jets from a newborn star slam into previously expelled gas clouds, heating them to extreme levels. These jets, powered by a protostar 20 times more massive than our Sun, stretch over 32 light years through space […]
Young Stellar Objects Are Prominent In A New Hubble Image January 13, 2026
A disparate collection of young stellar objects bejewels a cosmic panorama in the star-forming region NGC 1333 in this new image from NASA’s Hubble Space Telescope. To the left, an actively forming star called a protostar casts its glow on the surrounding gas and dust, creating a reflection nebula. Two dark stripes on opposite sides […]
Siwarha's Wake Gives it Away at Betelgeuse January 13, 2026
Betelgeuse is the star that everybody can't wait to see blow up, preferably sooner than later. That's because it's a red supergiant on the verge of becoming a supernova and there hasn't been one explode this close in recorded human history. It's been changing its brightness and showing strange surface behavior, which is why astronomers […]
