Mysterious signals from space could teach us how dark energy works
Weird bursts of radio waves from space could be used to measure cosmic distances, which would help us learn about dark energy and the universe’s expansion Source: https://www.newscientist.com/article/2212926-mysterious-signals-from-space-could-teach-us-how-dark-energy-works/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
Mysterious, Ancient Radio Signals Keep Pelting Earth. Astronomers Designed an AI to Hunt Them Down.
Sudden shrieks of radio waves from deep space keep slamming into our radio telescopes, spattering those instruments’ recordings with confusing data. And now, astronomers are using artificial intelligence to detect those outbursts. Source: https://www.livescience.com/66116-fast-radio-bursts-australia-artificial-intelligence.html
Dead planets can ‘broadcast’ for up to a billion years

Breakthrough Listen’s new search for alien lasers
For the last few decades, the search for extraterrestrial intelligence has focused on detecting radio signals. But a new collaboration between Breakthrough Listen and VERITAS will focus on looking for laser-like flashes of light.

Why hunting for fast radio bursts is an ‘exploding field’ in astronomy
Little more than a decade ago, two astronomers discovered mysterious bursts of radio waves that seem to take place all over the sky, often outshining all the stars in a galaxy. Since then, the study of these fast radio bursts, or FRBs, has taken off, and while we still don’t know what exactly they are or what causes them, scientists are…
There aren’t enough space explosions to explain strange radio bursts
Weird flashes of radio waves from space could in theory be coming from huge explosions, but now we know the radio bursts occur too often for that idea to work Source: https://www.newscientist.com/article/2209850-there-arent-enough-space-explosions-to-explain-strange-radio-bursts/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…

Fast radio burst pinpointed to distant galaxy
Fast radio bursts (FRBs) are among the most enigmatic and powerful events in the cosmos. Around 80 of these events—intensely bright millisecond-long bursts of radio waves coming from beyond our galaxy—have been witnessed so far, but their causes remain unknown.
