Globular Clusters: Already Old Nine Billion Years Ago

Globular Clusters: Already Old Nine Billion Years Ago

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. Plus, two new super-mercury exoplanets, This Week in Space History, and an interview with Eric Palmer about the DART mission.

Being a Star: Nature vs Nurture

Asteroseismologists 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. Plus, JWST images Mars, Hubble images stars, and SpaceX manages to launch another Starlink mission in spite of weather delays.

Jupiter’s Atmosphere Contains Metals From Planetesimals

Jupiter’s Atmosphere Contains Metals From Planetesimals

A recent paper examined data from NASA’s Juno mission and 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. Plus, a Voyager update, a new Mercury image, sulfur residue on Europa, and a review of “For All Mankind”.

JWST and the 30 Days of Terror

With the successful launch of the JWST, the focus turns to the complicated process of unfurling the sunshield and unfolding the mirror. We’ll look at just where NASA is in the process and how much farther we have to go before first light. Plus, Earth and supernovae, and in this week’s What’s Up, we look forward to 2022’s astronomy events.
