A magnetar has been discovered throwing off bizarre blasts of radiation. Is this where fast radio bursts come from

   11 Aug 00:00:06  |  Universe Today

Magnetars are the ultimate aggressive star: intense magnetic fields, massive outbursts, the works. We’ve known that magnetars are capable of producing some of the most powerful blasts in the cosmos, but new observations reveal a different kind of radiation: radio waves. This could potentially solve the long-standing puzzle of the origins of the mysterious Fast …

Neutron stars of different masses can make a real mess when they collide

   10 Aug 00:00:05  |  Universe Today

When neutron stars collide, they go out with a tremendous bang, fueling an explosion up to a thousand times more powerful than a supernova. But sometimes they go out with a whimper, and a recent suite of simulations is showing why: they turn into a black hole. The discovery of gravitational waves from colliding neutron …

An exoplanet has been found for the first time using radio telescopes

   10 Aug 00:00:05  |  Universe Today

Astronomers have found an extrasolar planet around a main sequence star. Which isn’t a big deal. With a radio telescope. Which is. Over the past couple decades astronomers have spotted thousands of exoplanets using a variety of techniques. There’s the ever-popular transit method, championed by observatories like Kepler and TESS. And there’s also a redshift …

Newly forming star has spiral arms like a tiny galaxy

   09 Aug 00:00:08  |  Universe Today

Protoplanetary disks – where young stars are forming their families of planets – usually form concentric rings of gaps. But astronomers have recently spotted a surprising situation: an adolescent star surrounded by galaxy-like spiral arms. As stars just begin to warm up, they surround themselves with layers upon swaddling layers of dust and gas. Very …

This is What the Solar System Really Looks Like

   08 Aug 00:00:15  |  Universe Today

At first glance, it looks like something from an alien autopsy. A strange organ cut from a xenomorph’s thorax, under the flickering lights of an operating room in a top secret government facility, with venous tendrils dangling down to the floor, dripping viscous slime. (X-Com anyone?) But no, it’s just our Solar System. This strangely …

Martian Features Were Carved by Glaciers, not Flowing Rivers

   07 Aug 00:00:12  |  Universe Today

Orbiters are giving us a chance to study the surface of Mars closely, and some of the features that pop to prominence are dry river channels. There are over 10,000 of them. But a new study suggests that glaciers on ancient Mars are responsible for many of them. According to the study, those glaciers and …
