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!🥂🚀🛰️🌌

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
