NASA - SPATIU - CHANDRA X-RAY OBSERVATORY
July 23, 2024: This image shows: This composite image features a spiral galaxy, viewed face on. Here, two blue and red speckled arms spiral around a black hole at the heart of the galaxy, known as NGC 7469. Faint clouds of pale blue mist trace the lines of the speckled arms, muting the colors in the image. Here, the black hole at the center of the galaxy is represented by a bright white dot encircled by a mottled, neon purple ring. This dot and ring represent X-ray emission from hot gas around the black hole. Due to the perfect face-on angle, six red diffraction spikes radiate from the glowing black hole, like laser beams...To celebrate the 25th anniversary of its launch, NASA’s Chandra X-ray Observatory is releasing 25 never-before-seen views of some of the most spectacular cosmic objects..These images, which all include data from Chandra, demonstrate how X-ray astronomy explores all corners of the universe. By combining X-rays from Chandra with other space-based observatories and telescopes on the ground, as many of these images do, astronomers can tackle the biggest questions and investigate long-standing mysteries across the cosmos..On 23 July 1999, the space shuttle Columbia launched into orbit carrying Chandra, which was then the heaviest payload ever carried by the shuttle. With Commander Eileen Collins at the helm, the astronauts aboard Columbia successfully deployed Chandra into its highly elliptical orbit that takes it nearly one-third of the distance to the Moon..“For a quarter century, Chandra has made discovery after amazing discovery,†said Pat Slane, director of the Chandra X-ray Center located at the Smithsonian Astrophysical Observatory in Cambridge, Massachusetts. “Astronomers have used Chandra to investigate mysteries that we didn’t even know about when we were building the telescope — including exoplanets and dark energy.â€.X-rays are an (Credit Image: © Chandra X-Ray Observatory Center/Cover Images v
