About a century ago, scientists were struggling to reconcile what seemed a contradiction in Albert Einstein’s theory of general relativity. Published in 1915, and already widely accepted worldwide by ...

Scientists have found a remarkably small yet bright object from the early universe that doesn’t make sense in our existing models of how stars and galaxies formed, even our own Milky Way. That means ...

Evidence of this quantum layer may be coming soon. Here’s what you’ll learn in this story: Physicists are still puzzling over ...

Scientists have shared a new theory about how the universe might end, not by fading away slowly, but by collapsing in on itself in what they call a “reverse Big Bang.” The idea suggests that after ...

I/ATLAS was first discovered on July 1, 2025, by the ATLAS telescope system in Hawaii. Its hyperbolic orbit, a trajectory not ...

The vast majority of matter is dark – invisible until it is detected only through its gravitational effects. The newly discovered object could be a clump of dark matter, or it could also be a compact, ...

The heart of the Milky Way could be holding the key to one of the universe’s oldest secrets. A mysterious glow of gamma rays in the centre of our galaxy has been a mystery for decades, but researchers ...

In a new study, scientists began pondering a pretty wild question: What if black holes can convert dead star matter into dark energy, the mystery force driving the acceleration of the expansion of the ...

An anomaly in the temperature of the universe has long stumped physicists, and a new analysis of data from several radio telescopes has only deepened the mystery of what is causing it. This weird ...
