astrobites

Sub-Neptunes are very good at hiding their secrets: many show flat spectra that could indicate multiple possibilities for their atmospheric composition. Yet some of these same worlds are caught in the act of losing hydrogen or helium to space. Could their escaping atmospheres reveal what their deceptively featureless spectra are hiding?

In 2019, CHIME detected a very unusual fast radio burst (FRB) signal that excited the astronomical community. However, it turns out that the signal wasn’t from an FRB after all…

Odd Radio Circles are a recently discovered extragalactic phenomenon. As their name suggests, the cause of them is still a mystery. This astrobites explores an ORC identified in LOFAR data that exhibits features that make it different from other ORCS

Fall is coming, which means graduate school applications will soon be upon us. In this post, you will find answers for many of your most pressing questions about applying to graduate school in the US, plus some additional resources and our friendly advice!

“An eclipse, a trombone and an oscilloscope walk into a bar” sounds like the beginning of a bad joke, but what do they have in common? Read on to find out.

Telescopes. Science Funding Cuts. The Commercialization of the night sky and what we can do to change it.

A close-in brown dwarf is a rare sight; but finding one around a massive, aging star is even rarer. Today's authors explore HIP 61637 b, an exciting case study that challenges known brown dwarf formation pathways!

The authors of today's paper explore how the neighbourhood a black hole grows up in may affect the rest of their lives with a new diagnostic tool.

Did Uranus’ major moons form out of debris left behind after a giant, planet-tilting impact? Spoilers: probably not.

What if the earliest galaxies weren’t unusual at all? Maybe the answer lies in relics left over from the universe’s first moments.

A new solution to Einstein’s general relativity suggests wormholes could be real and traveling through them might be possible.

Astronomers are on the hunt for the elusive starless ‘dark galaxies’ predicted by our model of the Universe. In this paper, learn about two newly detected dark galaxy candidates!

What might the next space-based gravitational wave detector look like? And what might it see? Today's authors explore these questions by comparing proposed future detectors, providing some insight into the post-LISA landscape.

When water began dripping through a leaking dome, the race was on to preserve an iconic astronomical landmark. Discover how an ambitious restoration project is securing the Round Tower in Copenhagen for generations to come.

There’s no need to storm Area 51 for evidence of UFOs, in today’s bite we explore the first detection of a UFO (ultra-fast outflow) in a quiescent galaxy!

Are you upset that the World Cup is over? Well, today’s bite has another contest for you to agonize over — the contest over which cosmological model best explains the Hubble tension!
