Fast radio bursts (FRBs) are one of the most intriguing mysteries of modern astronomy. Now a whopping eight new repeating signals have been detected.

In about five billion years’ time, the Sun will grow into a red giant, destroy the Earth and become a white dwarf star. But according to a new study, any aliens out there might still be able to pick up radio waves from Earth's planetary core – for up to a billion years.

Statistically it’s pretty much a given that alien life is out there, whether that’s Martian microbes or intelligent life beaming comms through the cosmos. Now, a new telescope array has joined Breakthrough Listen, scanning for flashes of laser light that alien civilizations might be giving off.

Fast radio bursts (FRBs) are one of the most intriguing mysteries of modern astronomy, so the more of them we can locate, the closer we get to figuring what causes them. Now astronomers have managed to trace an FRB back to its home galaxy, many billions of light-years away.

Scientists have been unable to figure out what fast radio bursts are or where they’re even coming from. Now, a team of astronomers has finally managed to trace one of the signals back to its home galaxy billions of light-years away, meaning we’re closing in on the culprit.

The SLAC National Accelerator Laboratory has developed a compact antenna that can transmit radio signals underwater, and even through solid earth. The new 4-inch (10-cm) antenna exploits the piezoelectric effect to generate Very Low Frequency (VLF) waves that normally require antennae miles long.

Active galactic nuclei are known by different names depending on the viewing angle. Now, for the first time astronomers have directly imaged the last piece of the puzzle that ties them all together – a dusty donut of material that surrounds a supermassive black hole.

Soma Laboratory has developed a handheld gadget that taps into the hidden voices of everyday modern objects, such as display screens, park railings and electronic doors. Ether picks up secret electromagnetic whispers and records the audio to a cabled audio recorder.​

A team of astronomers has used a global array of telescopes to peer through the fog and capture some of the clearest radio images yet of Sagittarius A*, the supermassive black hole at the center of the Milky Way. And it may indicate that the object just happens to be pointing directly at Earth.

The CHIME telescope has picked up 13 unexplained radio signals coming from beyond the Milky Way. These fast radio bursts are part of one of the strangest mysteries of modern astronomy, but the new detections could help unlock their source, thanks to a rare one that seems to be repeating.

In 1974, astronomers used the Arecibo Observatory to beam a message from humanity to the stars, in one of the most well-known attempts to contact possible alien life. For the 44th anniversary of the Arecibo Message, scientists are reaching out to the public for help in designing an updated version.

A huge radio telescope array spread across the Australian Outback is helping identify the mysterious fast radio bursts. Astronomers have now announced the discovery of 20 new FRBs in a bit over a year, including the brightest and closest events yet seen.
