Hi there! We're IPAC, a science and data center for astrophysics and planetary science.
www.ipac.caltech.edu
This is an image containing information about a science and technology meeting called RAPID Response: Hot-wiring the Next Generation of Time-Domain Science. The meeting dates are March 23-27, 2026 and the location is the Caltech campus in Pasadena, CA. More information about the meeting is at the website conference.ipac.caltech.edu/rapid-hotwiring2026.
How do we hot-wire the transient universe to enable breakthrough science?🤔🔌💡
The time-domain community is invited to a meeting by the
NASA Roman Alerts Promptly from Image Differencing (RAPID) team. Abstract submission and registration are now open!

Join us to learn why Pasadena is the "City of Astronomy" for a free afternoon of science demonstrations, solar telescopes, and public-level presentations on black holes, exoplanets, galaxies, space weather, and AI!
Sunday, November 16 Noon-4PM

The focus of the image is a portion of LDN 1641, an interstellar nebula in the constellation of Orion. In this view, a deep-black background is sprinkled with a multitude of dots (stars) of different sizes and shades of bright white. Across the sea of stars, a web of fuzzy tendrils and ribbons in varying shades of orange and brown rises from the bottom of the image towards the top-right like thin coils of smoke.

Three panels, each showing a different view of the binary star system Alpha Centauri. The panel on the left is a Digitized Sky Survey image showing a single bright blue point source at the center of a black image with stars scattered throughout. The center of this source is outlined with a vertical box, tilted slightly to the left, with two diagonal lines leading to the second panel. The 2nd panel is a Hubble image that shows 2 white stars with 4 diffraction spikes each against a black background. The top star is labeled Alpha Cen B and the bottom Alpha Cen A. Alpha Cen A is outlined with a white square with 2 diagonal lines leading to the 3rd panel at the furthest right, which shows a Webb image of the star. An orange star icon and central black circle outlined in white marks the location of Alpha Cen A. A large white circle outlines a blurry red-toned field that surrounds the location of the star. A bright orange blob at 9 o’clock in relation to the star is labeled “S1” and circled.

WELCOME TO THE FAMILY, ALPHA CEN A b!!!
First hinted at in Wagner+21, now Chas Beichman, Aniket Sanghi and team have published new JWST images of alpha Cen A showing another hint of this Saturn-sized planet candidate!

IPAC scientist finds evidence for a planet in the same star system as #Avatar 's Pandora!
If confirmed by additional observations, "Its very existence [...] would challenge our understanding of how planets form, survive, and evolve in chaotic environments."

“We’re immensely disappointed that our spacecraft didn’t get to the Moon, but the two science instruments we developed, like the teams we brought together, are world class,” said Bethany Ehlmann, the mission’s principal investigator at Caltech.
