      Since it began in 2020, NASA’s Citizen Science Seed Funding Program (CSSFP) has helped twenty-four new NASA citizen science projects get off the ground. This one-year funding opportunity aims to expand the pool of professional scientists who use citizen science techniques in their science investigations. We’d like to remind you about two key changes to the CSSFP program this year!
      First, we heard that researchers could make better use of seed funding if it arrived in time to enable work during the summer — a crucial season for students, faculty, and interns.  To address this need, NASA is shifting the submission and review process to earlier in the year. The planning start date for CSSFP investigations for this next round is now May 1, 2025! Of course, an earlier start date means an earlier due date, so this year’s CSSFP proposals will be due November 19, 2024. Proposers are also asked to submit a Notice of Intent (optional) by October 1, 2024 to aid in planning the review panels. 
      Second, if you are a current CSSFP grant recipient, you have the opportunity to request a No Cost Extension, which will allow you to continue spending your remaining funding during a second year. However, please note: the NASA Shared Services Center will reject late requests! All no-cost extension requests must be received more than 10 calendar days prior to the end date of your grant’s period of performance. Please check that date and be sure to submit your No Cost Extension requests more than 10 days prior.
      We’re excited to receive your proposals and can’t wait to help you do NASA science with fantastic volunteers from around the world!

      NASA/SAO/CXC This montage contains 25 new images with data from NASA’s Chandra X-ray Observatory that is being released to commemorate the telescope’s 25th anniversary in space, as described in our latest press release. Since its launch into space on July 23, 1999, Chandra has been NASA’s flagship mission for X-ray astronomy in its fleet of “Great Observatories.” Chandra discovers exotic new phenomena and examines old mysteries, looking at objects within our own Solar System out to nearly the edge of the observable Universe.
      There is a broad range of astronomical objects in this collection. At the center is one of Chandra’s most iconic targets, the supernova remnant Cassiopeia A (Cas A). This was one of the very first objects observed by Chandra after its launch in 1999, and astronomers have often returned to observe Cas A with Chandra since then.
      Chandra quickly discovered a point source of X-rays in Cas A’s center for the first time, later confirmed to be a neutron star. Later Chandra was used to discover evidence for a “superfluid” inside Cas A’s neutron star, to reveal that the original massive star may have turned inside out as it exploded, and to take an important step in pinpointing how giant stars explode.
      The Cassiopeia A supernova remnant has been observed for more than 2 million seconds since the start of the Chandra mission in 1999.

Temim (Princeton Univ.); Image Processing: NASA/CXC/SAO/J. Major, J. Schmidt and K. Arcand The unmatched sharpness of Chandra’s X-ray images are perfect for studying the hot debris and energetic particles remaining behind after supernova explosions. Other examples in this new collection include the Crab Nebula, G21.5-0.9, MSH 15-52, and SN 1987A. Chandra also probes the different branches of stellar evolution such as “planetary nebulas” when stars like the Sun run out of fuel and shed their outer layers as seen in the Chandra image of HB 5.
      Chandra also looks at what happens at the start of the stellar life cycle, providing information about some of the youngest and most massive stars. Images of these stellar nurseries in the “25 for 25” montage include the Orion Nebula, Cat’s Paw, M16 (a.k.a., the “Pillars of Creation”), the Bat Shadow and NGC 3324. A view of a more mature star cluster, NGC 3532, is also included. X-ray data are particularly useful for studying objects like this because young stars are often copious producers of X-rays, allowing stars that are members of clusters to be picked out of a foreground or background of older objects. Chandra’s sharp images and sensitivity also allow many more sources to be seen.
      This region of star formation contains the Pillars of Creation, which was made famous by the Hubble Space Telescope. Chandra detects X-rays from young stars in the region, including one embedded in a pillar.

Frattare Chandra observes galaxies — including our own Milky Way, where a supermassive black hole resides at its center. Chandra also studies other galaxies and this is represented in the new images of NGC 7469, Centaurus A, NGC 6872, NGC 1365, and Arp 220.
      Astronomers look at even larger structures like galaxy clusters with Chandra, where hundreds or thousands of galaxies are immersed in multimillion-degree gas that only an X-ray telescope can detect. In this release of images, M86 and the Virgo cluster, Abell 2125, and MACS J0035 are examples of galaxy clusters Chandra has observed.
      Closer to home, Chandra has contributed to the study of planets and comets in our own Solar System including Venus, Mars, Saturn, and even Earth itself. This ability to explore the Solar System is represented by the image of aurora on Jupiter, captured in X-rays, in this collection.
      A full list of the 25 images celebrating Chandra’s 25th, along with the data included and what the colors represent, is available at https://chandra.si.edu/photo/2024/25th/more.html.
      Images of some of these objects had previously been released, but now include new X-ray data or have been combined with different data from other telescopes. Some of these objects have never been released before with Chandra data.
      NASA’s Marshall Space Flight Center manages the Chandra program. The Smithsonian Astrophysical Observatory’s Chandra X-ray Center controls science from Cambridge Massachusetts and flight operations from Burlington, Massachusetts.

      The distorted spiral galaxy at center, the Penguin, and the compact elliptical at left, the Egg, are locked in an active embrace. This near- and mid-infrared image combines data from NASA’s James Webb Space Telescope’s NIRCam (Near-Infrared Camera) and MIRI (Mid-Infrared Instrument), and marks the telescope’s second year of science. Webb’s view shows that their interaction is marked by a glow of scattered stars represented in blue. Known jointly as Arp 142, the galaxies made their first pass by one another between 25 and 75 million years ago, causing “fireworks,” or new star formation, in the Penguin. The galaxies are approximately the same mass, which is why one hasn’t consumed the other.NASA, ESA, CSA, STScI To celebrate the second science anniversary of NASA’s James Webb Space Telescope, the team has released a near- and mid-infrared image on July 12, 2024, of two interacting galaxies: The Penguin and the Egg.
      Webb specializes in capturing infrared light – which is beyond what our own eyes can see – allowing us to view and study these two galaxies, collectively known as Arp 142. Their ongoing interaction was set in motion between 25 and 75 million years ago, when the Penguin (individually cataloged as NGC 2936) and the Egg (NGC 2937) completed their first pass. They will go on to shimmy and sway, completing several additional loops before merging into a single galaxy hundreds of millions of years from now.
      Learn more about the Penguin and the Egg.
