X-ray: NASA/CXC/SAO; Optical: Clow, M.; Image Processing: NASA/CXC/SAO/L. Frattare and K. Arcand This new view of the “Christmas tree cluster” NGC 2264, released on Dec. 17, 2024, combines data from NASA’s Chandra X-ray Observatory and optical data from astrophotographer Michael Clow’s telescope in Arizona. Chandra data is represented in red, purple, blue, and white, while optical data is in green and violet.
Located about 2,500 light-years from Earth, NGC 2264 is a cluster of young stars between one and five million years old. The stars are seen here as blue and white lights surrounded by swirls of gas—the “pine needles” of the tree—with green representing light in the visible spectrum.
Read more about the “Christmas tree cluster” – and the “cosmic wreath.”

Looking Out for ‘Lookout Hill’
NASA’s Mars Perseverance rover looked backward to capture this image of its tracks over monotonous terrain, using its Rear Right Hazard Avoidance Camera. Pico Turquino, a bedrock mesa on the Jezero crater rim, is just visible in the background. Perseverance acquired this image on Nov. 29, 2024 (Sol 1343, or Martian day 1,343 of the Mars 2020 mission), at the local mean solar time of 11:58:52. NASA/JPL-Caltech At Pico Turquino, a bedrock mesa on the Jezero crater rim, the science and engineering teams planned proximity science on Percy’s 30th abrasion patch, Rio Chiquito. SCAM and ZCAM characterized the rock near the abrasion, while SHERLOC and PIXL instruments were deployed for proximity science. The data from Rio Chiquito will help characterize the Pico Turquino area in addition to helping scientists understand the broader story and complex geologic history of Jezero crater.
NASA’s Mars Perseverance rover captured this image of the Rio Chiquito abrasion patch, using its SHERLOC WATSON camera, located on the turret at the end of the rover’s robotic arm. Image acquired on Nov. 20, 2024 (Sol 1334, or Martian day 1,334 of the Mars 2020 mission) at the local mean solar time of 16:18:39. NASA/JPL-Caltech After reaching the 30th abrasion milestone, Percy — along with the rover team back on Earth — took a couple of sols of much-deserved break over the Thanksgiving holiday before getting back to work.
Percy has since left Pico Turquino and has started moving to the next geologically significant stop, called Witch Hazel Hill. There is also a planned stop along the way near the highest point of the crater rim that the rover will traverse, a locale aptly named “Lookout Hill” where we will get outstanding views of both the interior of Jezero crater and the surrounding landscape, as if in a lookout tower. The path to get to these stops is mostly covered in regolith (soil) and lacks interesting rock outcrops, so the team’s focus over the next few weeks is on making and monitoring drive progress. As the rover drives, however, it will still have science cameras trained on interesting rock outcrops in the far distant hills to gather additional clues about the rocks that make up the Jezero crater rim.
Personally, I can’t wait for our stop at Lookout Hill, the apex of the crater rim, to see some gorgeous views inside and outside of Jezero from one of the highest spots around! Along with analyzing other returned data while Percy progresses toward Witch Hazel Hill, we’ll be anxiously scanning our post-drive images to look out for Lookout Hill coming into view
