This composite image of the Cassiopeia A (or Cas A) supernova remnant, released Jan. 8, 2024, contains X-rays from Chandra (blue), infrared data from Webb (red, green, blue), and optical data from Hubble (red and white). A study by the XRISM (X-ray Imaging and Spectroscopy Mission) spacecraft has made the first-ever X-ray detections of chlorine [...]
By the time the Artemis II Orion spacecraft launches to the Moon next year, its many components will already have traveled thousands of miles and moved across multiple facilities before coming together at NASA’s Kennedy Space Center. Branelle Rodriguez, Artemis II vehicle manager for the Orion Program, has overseen many parts of that journey. Her [...]
Photo of the Day It is still not known why the Sun's light is missing some colors. Here are all the visible colors of the Sun, produced by passing the Sun's light through a prism-like device. The spectrum was created at the McMath-Pierce Solar Observatory and shows, first off, that although our white-appearing Sun [...]
