A star near the centre of our galaxy reaches almost 3 per cent of the speed of light as it is whipped around something four million times the mass of the Sun that emits no light of its own — and tracking its orbit for nearly three decades helped two astronomers win a Nobel Prize
1+ hour, 23+ min ago (1100+ words) By Lachlan Brown · Editorial process Published July 25, 2026 Near the centre of the Milky Way, about 26,000 light-years from Earth, a young blue star repeatedly performs what looks like an impossible turn. It falls towards an object that cannot be seen, accelerates…...
Euclid opens a new window on the first billion years of cosmic history – Astronomy Now
6+ hour, 40+ min ago (785+ words) One of the biggest mysteries in modern astronomy is how the Universe managed to grow enormous black holes so quickly. Less than a billion years after the Big Bang, the Universe already contained quasars powered by supermassive black holes consuming…...
Scientists spot evidence of companion stars that blew up
12+ hour, 24+ min ago (678+ words) NASA scientists using the Chandra X-ray Observatory have made a new discovery showing that the Milky Way's outer spiral arms extend significantly farther than previously mapped. The findings, published on July 8, suggest astronomers may need to revise current models of…...
Astronomers Think They've Detected Antimatter Signals From Beyond The Milky Way For The First Time
5+ hour, 54+ min ago (565+ words) There's something wrong with the center of the Milky Way....
Scientists stunned by shocking link between heat theory and black holes revealed
7+ hour, 20+ min ago (260+ words) Jacob Bekenstein—the discoverer of black hole entropy—may not be as instantly recognizable a name as Stephen Hawking, but it’s thanks to his revelations that Hawking made his now-famous discovery: black holes can slowly evaporate, and this leads directly…...
Orion Nebula just revealed something nobody had seen before
8+ hour, 13+ min ago (766+ words) The Orion Nebula has long been one of the most familiar objects in the night sky. It can even be spotted with the naked eye on a clear night. After centuries of observations by nearly every major observatory on Earth,…...
Scientists May Have Finally Uncovered The Hidden Cause Behind The Sun’s Missing Silver
9+ hour, 33+ min ago (527+ words) Scientists may have solved a long-standing mystery about why the sun contains less silver than expected. The mystery emerged because models of galactic chemical evolution suggested that the sun should contain more silver based on the history of the stars…...
The 6 Most Interesting Paradoxes in Astronomy
15+ hour, 23+ min ago (974+ words) The most fundamental inquiries regarding space frequently prove to be the most challenging. Why is space perceived as dark? Why did the early Earth not freeze despite the Sun’s lesser intensity? Why is a star’s atmosphere hotter than its surface?...
Could We Send a Spacecraft to a Black Hole?
12+ hour, 8+ min ago (128+ words) Black holes represent some of the most extreme environments in the universe. They’re the sources of the strongest consistent gravitational fields, which allows us to test Einstein’s Theory of General Relativity to an extent that’s impossible with small objects. But…...
The Universe can outrun light without breaking Einstein’s rules
11+ hour, 36+ min ago (703+ words) This means that when a telescope captures the light from a distant galaxy, the image does not reveal where that galaxy is today. It shows the galaxy as it appeared when the light began its journey. To estimate its present…...
