Most exoplanets orbiting close to their stars don’t have atmospheres. But Gliese 486b – orbiting a red dwarf star only 24 light-years away – does. It’s close enough to see well. Astronomers will be watching it! Source: https://earthsky.org/space/gliese-486b-hot-super-earth-with-atmosphere…

Study shows a sharp rise in detection rate of broad absorption line variations
Gas around black holes and interstellar medium distribution are key factors in understanding the growth of supermassive black holes and the evolution of their host galaxies. However, as a crucial parameter, gas density is hard to determine reliably, because the general method is not applicable to all quasars.

Google-Free /e/ OS Is Now Selling Preloaded Phones In the US, Starting At $380
An anonymous reader quotes a report from Ars Technica: /e/ OS, the “open-source, pro-privacy, and fully degoogled” fork of Android, is coming to Canada and the USA. Of course, you’ve always been able to download the software in any region, but now (as first spotted by It’s Foss News) the e Foundation will start selling preloaded phones in North America. Previously,…

Linux Mint Developers Will Force Updates on Users Like Microsoft Does with Windows 10
AmiMoJo shares a report: Last month, the Linux Mint team published a post on the organization’s official blog about the importance of installing security updates on machines running the Linux distribution. The essence of the post was that a sizeable number of Linux Mint devices was running outdated applications, packages or even an outdated version of the operating system itself. A…
Aptera Promises The World’s First Mass-Produced Solar Car This Year
California-based Aptera Motors “is rolling out the first mass-produced solar car this year,” reports the Washington Post, after successfully crowdfunding a restart of their development effort: It’s a three-wheel, ultra-aerodynamic electric vehicle covered in 34 square feet of solar cells. The car is so efficient that, on a clear day, those cells alone could provide enough energy to drive about 40…

Evidence for white dwarfs consuming Earth-like worlds
For the first time, astronomers have detected the vaporized remains of the crusts of long-dead Earth-like and Mars-like planets in the atmospheres of white dwarf stars. Source: https://earthsky.org/space/vaporized-earth-like-mars-like-crusts-white-dwarf-stars…
Why does this galaxy look older than its years?
To the extent that we can see them, galaxies in the very early universe should look relatively young and unformed. But galaxy ALESS 073.1 is a surprise to astronomers: it looks more mature than we’d have any reason to expect. Why? Source: https://earthsky.org/space/galaxy-looks-older-than-its-years-aless-073-1…
Lack of symmetry in qubits can’t fix errors in quantum computing, might explain matter/antimatter
A team of quantum theorists seeking to cure a basic problem with quantum annealing computers—they have to run at a relatively slow pace to operate properly—found something intriguing instead. While probing how quantum annealers perform when operated faster than desired, the team unexpectedly discovered a new effect that may account for the imbalanced distribution of matter and antimatter in the universe…
