Last week, scientists and engineers across the International GMT Consortium hosted a 1-hour livestream offering insight into the progress and future of one of the world’s most ambitious scientific projects: the Giant Magellan Telescope. Watch it here: bit.ly/41KWDSV

Part of my new book, Second Ascent, is set at the Giant Magellan Telescope, being constructed around the world and assembled in Chile. It's fun to imagine something amazing that doesn't exist but soon will! One of GMT's goals is to find other Earths! Yeah, baby. giantmagellan.org/2025/12/16/t...

The Year in Photos 2025

2025 was a pivotal year for the Giant Magellan Telescope, defined by major construction milestones and strengthened global collaboration. We welcomed a new consortium partner and made substantial prog...

An unidentified reddish blob spotted by U of A astronomers has officially been confirmed as WISPIT 2c — a newborn giant planet about 10 times the mass of Jupiter and only 5 million years old. It's part of one of the youngest solar systems ever discovered! bit.ly/4ma4N0A

Earlier this month, Prize Fellow Aldana Grichener organized a packed multi-day nuclear physics workshop, designed to push the frontiers of this fast-moving field. Now, tutorials from the sessions are publicly available to explore! Access them here: bit.ly/3NZAtci

Here is watercolorist Thordis Maaske's impression of the Kappa Tucanae A star system, recently discovered by Steward postdoc Thomas Stuber. The discovery gives scientists their first natural "laboratory" for understanding hot exozodiacal dust. Learn more: bit.ly/4lUa24o

Steward Observatory grad student Himansh Rathore has led a new study revealing that the Small Magellanic Cloud was transformed by a direct collision with its neighbor — upending decades of assumptions about how we use it to study the universe. bit.ly/4sV2eSk

Big room, bigger questions! Thanks to Dr. Chris Impey for sparking rich conversation at last week’s SkillSpace workshop in science communication at @azastrobiology.bsky.social !

Steward teams are building instruments for Lazuli — a new space telescope launching by 2029 as part of the Eric & Wendy Schmidt Observatory System. Our adaptive optics will image giant exoplanets nearly a billion times dimmer than their host stars! bit.ly/4dkXYH1

The first University of Arizona Galaxy Slam brought together two of the university's biggest strengths – space science and basketball – in a weeklong celebration. Read Steward astronomers' reflections on the parallels between sports and astronomy: bit.ly/4shJyM5

U of A space scientists reflect on Galaxy Slam's debut

Three of the six scientists featured during the Galaxy Slam celebration spoke with Lo Que Pasa about what the initiative meant to them and why it matters for the university community.
