A population study of 43 exoplanets orbiting M-dwarf stars to find the densities of the worlds shows the planets are less dense than expected, suggesting they are not purely rock but half-rock and maybe half-water.
As if getting set on fire and tossed into space wasn’t enough, new research finds evidence that after the Chicxulub impact, dinosaurs were also the victims of a massive global tsunami and worldwide earthquakes. Plus, the Milky Way’s stellar graveyard, a new timeline for the Moon’s formation, and this week in space history, we look back at the Meteosat program
The quest to understand the formation mechanisms of globular clusters was limited by the Hubble Space Telescope’s ability to peer back in time. Now, JWST’s larger mirror has allowed astronomers to find gravitationally lensed galaxies that have globular clusters almost nine billion years old.
While astronomers have observed white dwarfs consuming companion stars on numerous occasions, for the first time, they have now observed the consumption of the companion’s helium and not just hydrogen.

NASA’s DART spacecraft arrived at the asteroid Didymos, targeted the moonlet Dimorphos, and successfully flung itself at the surface. Multiple observations confirm that the system brightened and even managed to resolve a cloud of debris.
Astroseismologists are combining data from TESS, Kepler, and eventually JWST to study stellar oscillations in ‘infant’ stars, with the goal of creating new models for how such young stars form and evolve over time
Listen to the full-length interview with Jian-Yang Li from our September 13th episode where we discuss the DART mission’s uh, impact… ;^D
As we return from our summer hiatus, we are back with a rundown of some of the stories such as JWST images, dark matter, and Betelgeuse. Also thirty orbital launches but not including Artemis.
Juno mission found that Jupiter’s atmosphere not only contains metals but also is not a homogenous mix. The likely culprits are the remains of planetesimals from the early solar system.
