Hubble Finds That Betelgeuse’s Mysterious Dimming Is Due to a Traumatic Outburst Observations by NASA’s Hubble Space Telescope are showing that the unexpected dimming of…
Planet-forming environments can be much more complex and chaotic than previously expected. This is evidenced by a new image of the star RU Lup, made…
Led by PhD student Zhen Wan and his supervisor Professor Geraint Lewis, an international team of astronomers has found a shredded globular cluster on the…
Stars viewed from a place called Dome A in Antarctica can finally be seen without their twinkle – which means in much greater detail. Have…
“Stellar archeology” reveals a star stream composed of the remnants of an ancient globular cluster that was torn apart by the Milky Way’s gravity 2…
The second most distant quasar ever discovered now has a Hawaiian name. Astronomers have discovered the second most distant quasar ever found, using the international…
A simple model explains a wide range of observations by describing a contest between galaxy halos and their central black holes that eventually turns off…
As dying stars take their final few breaths of life, they gently sprinkle their ashes into the cosmos through the magnificent planetary nebulae. These ashes,…
An exploding white dwarf star blasted itself out of its orbit with another star in a ‘partial supernova’ and is now hurtling across our galaxy,…
KyotoU’s new Seimei telescope detects enormous ‘superflare’ on nearby star The cold, dark chaos of space is filled with mystery. Fortunately, the ways in which…
An international team of astronomers has created the most detailed map yet of the atmosphere of the red supergiant star Antares. The unprecedented sensitivity and…
Astronomers created a stunning new image showing stellar fireworks in star cluster G286.21+0.17. Most stars in the universe, including our Sun, were born in massive…
Using the European Southern Observatory’s Very Large Telescope (VLT), astronomers have discovered the absence of an unstable massive star in a dwarf galaxy. Scientists think…
Most massive stars are born in binaries (and sometimes triples, quadruples, and so on—being single isn’t common for such rock stars!) As stars age, they…
Astronomers have reported the first detection of X-rays from the earliest phase of evolution of a star like our Sun. This discovery from NASA’s Chandra…
Computer simulations conducted by astrophysicists at Tohoku University in Japan, have revealed a new theory for the origin of supermassive black holes. In this theory,…
Astronomers tend to have a slightly different sense of time than the rest of us. They regularly study events that happened millions or billions of…
Astronomers using European Southern Observatory (ESO) telescopes have discovered giant spots on the surface of extremely hot stars hidden in stellar clusters. Not only are…
