The MeerKAT radio telescope array is finally up and running in South Africa. To show off what the facility can do, astronomers have pointed all 64 antennas towards the center of the Milky Way galaxy, and snapped one of the clearest shots ever taken of the mysterious region.

Fast radio bursts (FRBs) are strange, extremely bright and mysterious signals from space. Now, astronomers at Australia’s Parkes Observatory have recorded three new signals in relatively quick succession – one of which is the brightest FRB ever detected.

Drones are increasingly crowding the airspace, so it’s only natural that the counter-drone market is growing too. The wide arsenal from DroneShield just got a little wider with the DroneGun Tactical, a new handheld jamming weapon that disrupts more frequencies from a smaller, more portable package.

Last year astronomers around the world witnessed the merger of two neutron stars as gravitational waves, light, radio and gamma rays, but the aftermath of the mashup hasn’t played out quite as expected. Rather than fade over time, the afterglow has continued to brighten.

An international team of astronomers has found that a strange repeating fast radio burst is even odder than previously thought. The radio waves from FRB 121102 are being “twisted” to an extreme degree, indicating that highly-magnetized plasma could be interfering.

You can't get much more mysterious than the interstellar asteroid 'Oumuamua, but is it mysterious enough to be an artificial probe designed by a spacefaring alien civilization? Researchers at the Breakthrough Listen initiative want to find out.

While SETI is content to scan the skies for signals, Messaging Extraterrestrial Intelligence (METI) takes a more active approach. Radio transmissions containing snippets of music have been sent to a potentially-habitable planet about 12 light-years from Earth, in hopes of making first contact.

Fast Radio Bursts (FRBs) have puzzled astronomers since they were first detected 10 years ago. Normally FRBs fire off once and aren’t heard from again, but one has repeated over the years, and this week it has kicked into hyperdrive, pulsing an unprecedented 15 times in the space of a few hours.

Humankind has long looked at the stars and wondered if there is intelligent life out there. And if so, could we contact them? There are a few options, but which has the greater chance of success? Sending radio messages or unmanned probes? Let's have a look.

Back in May, the Arecibo Observatory detected strange radio signals coming from Ross 128, a red dwarf star 11 light-years away. After analyzing the data closely with the help of the SETI project, the team has now revealed what they believe to be the source of the signals.
