1+ day, 15+ hour ago   (88+ words) The most comprehensive catalogue of exploding white dwarf stars ever assembled has revealed new clues about dark energy, the mysterious force driving the universe’s accelerating expansion....

3+ day, 17+ hour ago   (219+ words) The eROSITA Consortium has issued the survey's second data release (DR2), nearly doubling the previously known eROSITA X-ray sources to two million....

3+ day, 21+ hour ago   (417+ words) In 2009, astronomers using the Fermi Gamma-ray Space Telescope discovered an excess of energy in the Milky Way's galactic center. Deep observations found no source for the energy, called the Galactic Center GeV Excess (GCE). What's generating it? Research in Physical…...

4+ day, 21+ hour ago   (862+ words) A distant star has captured astronomers' attention over the past decade, teasing them with indications that it will soon explode as a supernova. But new research shows that something else entirely is behind the star's outbursts. Rather than an impending…...

5+ day, 3+ min ago   (641+ words) Astronomers refine their understanding of gas movement by observing it in more types of environments, and in more complex environments. Researchers in Japan recently used CO observations to map gas in an especially complex and unique environment: Stephan's Quintet. The…...

1+ week, 6+ day ago   (700+ words) Universe Today Black holes are some of the most awe-inspiring and mysterious celestial objects in the universe. This is primarily because astronomers still don’t understand the underlying mechanisms that drive black holes, including its formation, evolution, and end. As their…...

3+ week, 4+ day ago   (496+ words) Stars are a critical piece of the larger cosmos. They're engines of nucleosynthesis, forging the elements—and the planets—that make life possible. Their feedback regulates physics on a galactic scale, they can serve as standard candles that let us…...

3+ week, 4+ day ago   (273+ words) This NASA/ESA/CSA James Webb Space Telescope Picture of the Month takes us to a fantastical realm within our home galaxy, where piercing starlight and billowing winds sculpt dust clouds into inventive shapes. This scene is from the Carina…...
