4+ hour, 2+ min 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....

1+ day, 4+ hour ago   (335+ words) Venus likely never had a moon and even if it did it would have soon been torn asunder by the planet’s own gravity, says prominent planetary astrophysicist....

1+ day, 7+ hour ago   (185+ words) Light could only travel freely in the Universe after cosmic reionization. Before that, neutral hydrogen stopped photons from travelling. The JWST has found evidence of an overdensity of galaxies carving out a bubble of reionization. Is this how it all…...

2+ day, 6+ 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....

2+ day, 9+ 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…...

2+ day, 15+ hour ago   (132+ words) The James Webb Space Telescope (JWST) has opened up many wonders of the cosmos to scientists since it began its science operations a few years ago. But one thing that it hasn’t done is find an “exomoon”. These, as yet…...

3+ day, 3+ hour ago   (28+ words) UK astronomers have uncovered new clues about the origin of 3I/Atlas – only the third known object from beyond our Solar System ever spotted in our cosmic neighbourhood....

3+ day, 5+ hour ago   (517+ words) Universe Today Shortly after the James Webb Space Telescope (JWST) became operational, it directed its sophisticated infrared optics towards the early Universe. There, it observed an abundance of small red objects that turned out to be high-redshift galaxies that existed…...

3+ day, 10+ 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…...

3+ day, 13+ hour 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…...
