Radio

Researchers at NIST have shown that a cloud of atoms can be used as a receiver to pick up video transmissions. The team demonstrated this “Atomic Television” by transmitting live video feed and even video games through the atoms to a monitor.

Astronomers have detected an extremely strange radio signal from a distant galaxy that pulses with a heartbeat-like rhythm. This signal lasted about 1,000 times longer than other fast radio bursts, and had a clear periodic pattern to its pulses.

Astronomers have discovered a strange neutron star that challenges our understanding of them – but may help unlock the mystery of fast radio bursts. The object spins far slower than any known neutron star, and gives off seven types of radio pulses.

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.
