Radio

Astronomers have discovered what may be the brightest pulsar in the sky. Despite its intense light the pulsar has long evaded detection, and was only revealed thanks to a telescope equipped with some cosmic “sunglasses.”

A strange star just got even stranger. In the midst of its death throes, the star V Hya has been belching out a series of rings and plumes of materials, in a pattern never before seen from a dying star.

Astronomers may be a step closer to solving a cosmic mystery known as odd radio circles. New images, captured by the MeerKAT radio telescope, are the clearest and most detailed yet taken, narrowing down the list of suspects as to what creates them.

A new signal deepens the mystery of fast radio bursts with a few oddities – it hails from an unexpected region of space, and its pulses are about a million times shorter than most, which could indicate many others like it are going undetected.

Astronomers have discovered a bizarre radio signal in our galaxy that can’t be explained by any known object. When active the source gives off radio bursts lasting a minute, every 20 minutes, which should be impossible based on what we know about it.

Astronomers have spotted two “invisible” galaxies hiding near the dawn of the universe. The team used radio waves to peer behind a curtain of dust, and the find suggests that there were far more galaxies in the early universe than previously thought.

A huge new dataset could soon help unlock the mystery of fast radio bursts (FRBs). Within a few weeks, over 1,600 new signals were detected coming from one of the most well-studied sources, essentially ruling out a leading hypothesis on their origin.

Astronomers have detected a strange radio source from near the center of the Milky Way. The signal repeats seemingly at random and can’t be attributed to any known astronomical object, leading the team to consider that it may be something brand new.

Astronomers have discovered strange radio signals that could be coming from unseen planets. Models suggest that interactions between the magnetic fields of planets and their host stars produce radio emissions – a new potential way to detect planets.

Astronomers have spotted a new type of supernova for the first time. An unlucky star seems to have prematurely exploded after colliding with an extremely dense object, perhaps a black hole or a neutron star, creating a unique signature in the sky.

We might be one step closer to an answer for the intriguing cosmic mystery of fast radio bursts. By examining multiple “radio colors” simultaneously in a batch of repeating signals, astronomers have ruled out a leading model for their origin.

Astronomers have taken a close-up image of a jet emitted by a supermassive black hole for the first time. The Event Horizon Telescope has zoomed in on the jet with 16 times the resolution and at 10 times higher frequencies than previous observations.
