Wilson et al. have found a system of four #exoplanets orbiting a red dwarf star, in the sequence: rocky - gaseous - gaseous - rocky again. This spans the radius valley within a single system, and distinguishes between two different planet formation theories. ☄️🔭🧪 www.science.org/doi/10.1126/...

Oh now this is VERY cool! Denis+ on “Cold and eccentric: a high-spectral resolution view of 51 Eri b with VLT/HiRISE” where radial velocity measurements of the exoplanet enable a determination of the 3D orbit, and therefore you can calculate the PHASE as seen by Earth! #astrodon #exoplanet ☄

A tidally-locked rocky #exoplanet orbiting close to its host star could have tidal waves of lava sweeping around the planet.

Reading (and thoroughly enjoying) “The Possibility of Life” by Jaime Green, and who should appear as a source? @aussiastronomer.bsky.social talking about the #exoplanet archive at JPL and working with creatives to entice readers to read about the new discoveries.

In 2017, it was suggested that the Wow! Signal might have been produced by hydrogen emissions from comets. Ironically, the Big Ear telescope had already observed Comet Halley three decades earlier, in August 1986, and it produced no Wow!-like signal, nor was any such signal expected. #AreciboWow

We uncovered decades of previously unknown all-sky radio data from the Big Ear telescope, collected during a much quieter radio-era with active interference cancellation. Here are the projects, receivers, and the methods used to record the data. #AreciboWow #RadioAstronomy
