Closest pair of supermassive black holes headed for monster merger

Astronomers have discovered the closest pair of supermassive black holes yet known – and that record has two meanings. Not only are they the closest pair to Earth, but they’re the closest to each other as well, barreling towards each other for an event… Continue reading Closest pair of supermassive black holes headed for monster merger

Glow of “cosmic web” filaments directly imaged for the first time

On a scale that’s hard to fathom, the universe is made up of a “cosmic web” of hydrogen filaments that feed and form galaxies. Now, astronomers have made the first direct observations of light from this web, by staring at a patch of sky with a powerful… Continue reading Glow of “cosmic web” filaments directly imaged for the first time

Triple star system found with weirdly warped planetary disc

It can be easy to assume that the way things are in our solar system are mostly how they are elsewhere in the universe – but that’s often not the case. Now, astronomers have observed a triple star system that’s warping and splitting its planetary disc … Continue reading Triple star system found with weirdly warped planetary disc

One of the most massive stars in local universe may have disappeared

A star that shined with 2.5 million times the light of our Sun has disappeared from the night sky. It is possible that the star collapsed into a black hole without first triggering a supernova – a rare event, even in the context of dying stars.Continue… Continue reading One of the most massive stars in local universe may have disappeared

Asteroid that had a chance to hit Earth in September is a no-show

A few months ago, the asteroid 2006 QV89 grabbed headlines thanks to it having a slim chance of striking Earth this September. But now it seems that the potentially-hazardous space rock has missed its appointment. ESA has confirmed that the a… Continue reading Asteroid that had a chance to hit Earth in September is a no-show

Astronomers pinpoint location of mysterious radio signal across the universe

Fast radio bursts (FRBs) are one of the most puzzling mysteries of the space age. These one-off, millisecond-long signals pour in from all corners of the cosmos, and so far nobody’s been able to figure out what causes them or where they’re ev… Continue reading Astronomers pinpoint location of mysterious radio signal across the universe

Thermal vision highlights Uranus's rarely-seen rings

Thermal images taken of Uranus, showing the planet's rings clearly

Although Saturn sports the most impressive ring system in our neighborhood, it’s not alone. Uranus is also packing some rings, although they’re usually too faint to see without a powerful telescope. But a striking new set of images shows these rings in very clear detail thanks to thermal imaging, while also allowing astronomers to measure their temperature for the first time.
