The Red Planet Has a Purple Side (opens the original)
Read excerpt
Oxidized iron dominates the Martian colour palette. The dusty reds, ochres, browns, and tans give the planet its nickname: the Red Planet. But new images of Mars' south pole region show something different. Swirls of pink, purple, and red highlight the region and a feature named Thyles Rupes, an icy crag with cliffs higher than 1 km. Rupes means cliff in Latin, while Thyles is a mythical northern land spoken about in the ancient world. All of the different colored materials in this region have d
A Zombie White Dwarf Star is Born Again. Hallelujah! (opens the original)
Read excerpt
Stars go through a host of changes as they evolve, but most of the time, those changes play out on astronomical timescales. Supernovae are an exception to this, but they're rare, and most stellar changes take millions or billions of years to play out. Not so with one star named Sakurai's object. Sakurai's object is a star that has shifted identities, and is often described as 'born again.' It was a main sequence star that swelled up and became a red giant. After that, its evolution continued and
When Stars Engulf Rocky Planets, Beryllium Gives It Away (opens the original)
Read excerpt
Binary stars are born in the same cloud of molecular gas, and should share the same chemical composition. But sometimes they don't. Is this because of minor differences in the protostellar clouds? Or is it because some stars have eaten, or engulfed, rocky planets? If rocky planets are regularly consumed by their stars that's a bad sign for habitability. An international team of researchers have found a way to determine if stars have eaten rocky worlds that strayed too close. It's based on Beryll
If Venus Had An Ancient Moon, It Was Doomed (opens the original)
Read excerpt
You don't hear it much anymore, but people used to refer to Venus as Earth's 'sister planet'. They're very close in size and composition, so it made sense. There are obvious differences between the two, though. While Earth is warm, wet, hospitable, and resplendent with life, Venus is a blistering hell-hole. Planetary scientists like to puzzle over these differences. But there's another difference that also begs for attention. While Earth has a moon, Venus does not. Why is that? Did it ever have
Dense Galaxies Are Carving Out A Bubble in the Early Universe (opens the original)
Read excerpt
When the JWST's first science results started rolling in, it was a triumph for scientific vision and persistence. For years, the fate of the powerful space telescope was uncertain. It went way over budget, and for 25 years, troubling conversations accompanied its ongoing development. Several times, it seemed like it would be cancelled, and in 2011, congress came close to ending the program. So when it was finally launched on December 25th, 2021, there was a collective sigh of relief in the astro
