Hard to believe it's already been 2 years since the ngVLA prototype antenna was first unveiled at mtex in Germany!
Since then, the panels have been installed, the dish lifted onto its pedestal, and the antenna was officially handed over to the NRAO.

New paper from our group and @madysonbarber.bsky.social today!
We report a brand-new planet around a <50 Myr star—adding to a very small (but rapidly growing!) population of the youngest known transiting planets.

It’s amazing that comet #3IAtlas has wandered the Galaxy for billions of years, untouched and unnoticed, until it finally brushed past our Sun. I can’t help wondering where its journey will take it next, and what will have become of Earth by then. 😌

This summer scientists put forward 100 ideas for the ‘scope including planetary defense, studying Venus, and even observing individual stars in distant galaxies.

Hey you. YES YOU. Super persnickety astronomer. You know who you are.
NASA Exoplanet Archive just updated our overview pages so the stars are closer to their actual colours, as per Harre & Heller (2021) and Cranmer (2021).
You're welcome. 😎
