Jacob Jencsen, a staff scientist at IPAC, led a a study that reveals intricate layers of interstellar dust and gas around the Cassiopeia A supernova remnant. Jencsen's team presented their findings in a press conference at the 245th meeting of the American Astronomical Society in National Harbor, Maryland.

Technicians have successfully integrated NASA’s Nancy Grace Roman Space Telescope’s payload – the telescope, instrument carrier, and two instruments – to the spacecraft that will deliver the observatory to its place in space and enable it to function while there.

Spock's home planet is probably one of the most famous exoplanets, thanks to Star Trek lore. Turns out, Vulcan has a storied past in our own solar system's history, which Dr. Ben Montet shares in the second half of his chat with Jessie. But is Vulcan a real planet that actually orbits the real star called 40 Eridani A? Tune in and find out!

At the American Astronomical Society's 245th meeting (January 12-16, 2025), ENSCI is organizing a special session on Euclid. ENSCI staff will be at the IPAC booth to answer Euclid-related questions.

A fun, exciting new way to explore astronomical data! The image of a star-forming region, M78, taken by the Euclid mission has been converted to a cosmic jingle.

Euclid Quick Release 1 (Q1) data will go public on March 19, 2025! These include the imaging and spectroscopic data from a single visit to the Euclid Deep Fields, totaling 53 square degrees in sky coverage.

Dimensions of IPAC explores the wide spectrum of activities happening at IPAC, and here we highlight IPAC's role in the SPHEREx mission.

NASA and SpaceX are targeting late February 2025 for the launch of the agency’s next astrophysics observatory, SPHEREx. Short for Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer, SPHEREx will launch aboard a SpaceX Falcon 9 rocket from Vandenberg Space Force Base in California.

Know Thy Star 2 focuses on the effects that stars have in limiting our ability to determine planetary masses, orbits, bulk compositions, and atmospheric abundances - and the state of the art knowledge and techniques that have been developed to mitigate the stellar effects. By Knowing thy Star, we can better Know Thy Planet!

The Zwicky Transient Facility (ZTF) and IPAC at the California Institute of Technology announce ZTF Public Data Release 21.
