11+ hour, 20+ 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, 14+ 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, 22+ 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, 10+ 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, 20+ 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…...

5+ day, 21+ hour ago   (161+ words) Each of the quiet black holes we've discovered this way has a small stellar companion. This means that in the past these were asymmetrical binaries, meaning that one of the stars was much larger than the other. The remnants of…...

1+ week, 2+ day ago   (188+ words) In 1992, Centaur 450P/LONEOS had a close encounter with Saturn, shifting its orbit closer to the Sun. Now astronomers can observe how a small icy body transforms into a comet over time....

1+ week, 4+ day ago   (196+ words) Prior to its launch, astronomers were uncertain what the powerful JWST would find in the ancient, early Universe. One of its surprising findings was Little Red Dots, unexplained ancient objects. They're widely considered to be connected to the growth of…...

1+ week, 6+ day ago   (840+ words) The planet Jupiter hosts more than 100 moons with the majority of attention going to the four Galilean moons, Io, Europa, Ganymede, and Callisto. This is primarily due to their active geology, including Io being the most volcanically active planetary body…...

2+ week, 18+ hour ago   (957+ words) How do scientists know the mass of the Universe? Measuring it has traditionally relied on knowing how many stars there are in galaxies, as well as clouds of gas and dust, and associated dark matter. Astronomers generally use the mass…...
