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.

DART Mission Successfully Boops Dimorphos

DART Mission Successfully Boops Dimorphos

After ten months of space travel, 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. Plus, rocket launches, an update on the SLS, some broken physics, and International Observe the Moon Night.

Quasar’s Light Echoes After 6.73 Years

Astronomers using the 1.2-meter Whipple Observatory to follow the brightness of a lensed galaxy for 14.5 years have calculated that the time delay between light arriving along the shortest and farthest paths is 6.73 years. Plus, DART, Hayabusa2, Juno, fast radio bursts, and This Week in Space History, we look back at NASA’s 1990s attempts to reach Mars.

NASA Tries Fuel Tanking the SLS Again

NASA Tries Fuel Tanking the SLS Again

In advance of the next scheduled launch attempt, NASA conducted another test to fill the fuel tanks onboard the Space Launch System rocket. The results were mixed, but the launch is still on schedule. Plus, a crewed launch, beautiful images, and an interview with Mike Simmons from Astronomy for Equity about sending telescopes to underprivileged students.

Being a Star: Nature vs Nurture

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.
