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

This color image shows a young man from the shoulders up smiling directly at the camera. He has dark, tightly curled hair and is wearing a dark, thin-framed pair of eyeglasses and a mustard-yellow T-shirt. The background is a soft-focus, shallow depth-of-field view of green leafy plants and foliage, with some architectural elements faintly visible, suggesting an outdoor garden or park setting during the daytime. The lighting is soft and natural. On the bottom-left corner of the image is text that says 2026 IPAC Visiting Graduate Student Research Fellow; in the bottom-right corner is an orange box with text that says "Alex Rodriguez University of Michigan Using weak lensing to detect cosmic filament IPAC Advisors: Andreas Faisst & Kyle Finner."

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...

This is a photo of the March 2026 Nature Astronomy cover with signatures from the artist, Keith Miller, and the four study leads whose work is being featured: Ahmed Soliman, Stuart Shaklan, Eliad Peretz, and John Mather. The journal's cover art depicts a ground-based telescope sending a laser to a space-borne shade that is blocking the Sun's light, making it easier to observe nearby planets. The text on the cover says "Imaging a nearby habitable world from the ground." Image credit: Harriet Brettle/Caltech-Keck Institute for Space Studies.

Our IPAC community is in shock at the sudden loss of our colleague and friend, Carl Grillmair. His curiosity and dedication shaped IPAC in countless ways. We've dedicated our science talk series, The Next Seven Minutes, to his memory.🔭 www.ipac.caltech.edu/news/ipac-mourns-passing-of-carl-grillmair

This is an image of Caltech astrophysicist Carl Grillmair.

Visual description: The image focuses on Carl's head and shoulders; he is wearing a white shirt with gray stripes with short sleeves, and he is looking directly at the camera and smiling. Carl has a busy brownish-red bear and hair and with gray eyes.
