1+ day, 22+ 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…...

3+ day, 7+ 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…...

4+ day, 4+ 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…...

4+ day, 10+ hour ago   (157+ words) A few hundred million years after the Big Bang, the first stars ignited - literally the “let there be light” moment for the universe. Now known to astronomers as Population III, or Pop III, stars, these giants were very different from…...

5+ day, 1+ hour ago   (766+ words) Earth's surface water puts the planet into its own, privileged category among the Solar System's bodies. Nowhere else is it found, and this water allowed life to appear and fluorish. Nobody argues that, but what's still up for debate is…...

5+ day, 10+ hour ago   (105+ words) As with many insightful theoretical breakthroughs, it comes at a time of contradictory observational evidence. Thomas Kuhn would be proud. Over the past few years, the James Webb Space Telescope (JWST) and other new observatories have been looking back to…...

1+ week, 3+ day ago   (20+ words) Researchers at UCSB and UT Austin have determined that a galactic merger kicked a supermassive black hole into intergalactic space....

1+ week, 4+ day ago   (68+ words) Keeping track of time in the universe is a difficult task. It’s constantly evolving and changing, and studying events that happened billions of years ago, while possible, isn’t exactly easy. A recent paper in the Monthly Notices of the Royal…...
