NASA is launching its next great observatory, the Roman Space Telescope in September 2026. What will it do? What new discoveries is it expected to make? Join us for our next Stargazing Lecture from Senior Research Scientist Dr. Lee Armus to learn more! outreach.astro.caltech.edu

That's a wrap! 🎉 The Shifting Landscapes Conference brought together the Roman community at @caltechipac.bsky.social for four days of exciting presentations and discussion on the science Roman will unlock. The countdown continues: Roman launches August 30! Are you ready? 🚀🔭 #ShiftingLandscapes

The IPAC: Your Passport to the Universe splinter session at #AAS248 featured a live Roman Coronagraph Instrument demo with....LASERS — a fun way to preview the Roman Coronagraph tech demo and celebrate IPAC's 40th! We all had fun! #ExpandOurView #NASARoman #RomanCoronagraph

Announcing the 118 selected programs for #Roman Cycle 1! Spanning a vast scope from the solar system to large scale structure, the selections include 61 Small, 45 Medium, and 12 Large programs (featuring 5 new General Astrophysics Surveys). 🚀 Full list: bit.ly/4xXPz4i #ExpandOurView

🚀This summer's Roman Science Conference kicks off this week at Caltech! "Shifting Landscapes in Astrophysics" brings together the community to explore the exciting science ahead with the Roman — from cosmology to exoplanets to the transient universe. See you there! 🔭✨ #ShiftingLandscapes

It's been a blast hosting Alex Rodriguez as a Visiting Graduate Student Research Fellow this summer! Alex joined us in Pasadena from @umich.edu to hunt dark matter filaments connected to #galactic clusters with @kylefinner.bsky.social & Andreas Faisst.🌌🔭www.ipac.caltech.edu/page/graduate-fellowship

#TBT to an incredible week at #AAS248 in our hometown of Pasadena! IPAC brought the heat (and the infrared) with groundbreaking science, packed rooms, big announcements, and a reason to party! 🔭 See you at the next AAS in Salt Lake City!

Welcome RayJay! 🔭 🤩

Caltech@caltech.edu · last mo.

Today, Caltech and JPL welcome renowned astrophysicist, acclaimed author, and transformative leader, Ray Jayawardhana as the Institute’s tenth president! He brings a fierce commitment to building on Caltech’s legacy of discovery and exploration. Welcome to the frontier, RayJay! l1nq.com/uci46q8

What a star-studded celebration!✨🔭 We're still over the Moon from celebrating #IPAC40 at #AAS248! Nearly 300 people joined our party to enjoy food, drinks, and stamping their Passports to IPAC to win merch. Huge thanks to the sponsor, @baesystems.com! Here's to 40 more years of discovery!🥂🚀🛰️🌌

XLSSC 122 is the cosmic rule-breaker scientists didn’t see coming🫣 This is the earliest galaxy cluster to exhibit strong gravitational lensing, bending light from galaxies behind it, and breaking the record of the previous oldest cluster by a few billion years! www.ipac.caltech.edu/news/new-jws...

At #AAS248, astronomer and former IPAC Director George Helou gave a fantastic plenary talk, mapping 40 years of infrared astronomy and IPAC's pivotal role in the field. As we celebrate #IPAC40 this year, we look back on IRAS and Spitzer—and look ahead to Roman, NEO Surveyor, and the next 40 years!

CoRoT-2 b is flipping the script 😵‍💫 ❤️‍🔥 🔭 Typically, hot Jupiters are tidally locked, meaning one side always faces their star. But new research from Aurora Kesseli, staff scientist at NExScI, suggests CoRoT-2 b isn't tidally locked! www.ipac.caltech.edu/news/oddball...

The NITARP 2027 application is now available! NITARP gets teachers involved in real astronomical research. We partner small groups of educators with a mentor professional astronomer for an original research project. The program runs Jan-Jan. Applications due 15 Sep 2026. 🔭🧪🎢

Now at IRSA: The Euclid Galactic Bulge Survey (EGBS) consists of VIS imaging, photometry, and astrometry over 9 fields (4.8 sq deg). This dataset is an unprecedented deep, wide-field, high-resolution view of the inner bulge region of our Milky Way galaxy. irsa.ipac.caltech.edu/data/Euclid/...

No less than 60 million stars in one image. It's possible thanks to ESA's Euclid mission. For just one day, Euclid turned its gaze to the crowded heart of the Milky Way and captured the largest, most detailed photo ever taken of our galaxy's centre in visible light. Let's dive deeper 👇 🔭 🧪 ☄️ 1/8

Euclid captures the Milky Way’s crowded heart 📸 🧡 🔭 The largest and most detailed visible light image ever made of the center of our Milky Way is revealed by @esa.int’s Euclid mission 🎉 Quick Release 2 data is now available in @irsaipac.bsky.social ! euclid.caltech.edu/news/esa-s-e...
