✨At exactly this moment 20 years ago, Space Shuttle Columbia lifted off the launch pad @NASAKennedy in Cape Canaveral, Florida. Its mission: to carry @NASA 's Chandra X-ray Observatory into #space #Happy 20th anniversary Chandra! #Chandra20 More: On July 23, 1999 at 12:31 a.m. EDT, the solid rocket motors in the solid rocket boosters on NASA Shuttle Transportation System 93 (STS-93 ) ignited. Under the command of Col. Eileen Collins, the first woman to command a NASA shuttle mission, Space Shuttle Columbia lifted off and NASA's Chandra X-ray Observatory began its journey into space. Two minutes later, the burn from the Solid Rocket Boosters was completed and the boosters separated from the shuttle. Parachutes blossomed and carried the boosters gently into the Atlantic Ocean where they were recovered. Eight minutes after launch the main engine cut off and the disposable external fuel tank separated. Forty-five minutes after launch the shuttle orbiter Columbia achieved a circular orbit 320 kilometers (200 miles ) above Earth. At two hours into the mission, the payload doors opened and the astronauts prepared to deploy the Chandra X-ray Observatory. For six hours, while Columbia silently orbited Earth, all the systems on the Chandra spacecraft were checked out and the satellite reached equilibrium with the conditions in space. Eight hours and 42 minutes after launch, a small spring gently catapulted the giant satellite into space. Columbia pulled away a safe distance, and at 9 hours and 41 minutes into the mission, the first of two solid rocket motors attached to Chandra's spacecraft module ignited. The rocket burned for two minutes before shutting off and separating from the spacecraft. Three minutes later the second rocket fired. These firings lifted the Chandra X-ray Observatory into a highly elliptical orbit that took the satellite 64,000 kilometers away from Earth before returning to a closest approach of 320 kilometers. The solar panels deployed and the second solid rocket motor separated. (Continued in the comments... )

Discover how an X-ray telescope has revolutionized @astronomy and our understanding of the Universe. A scientific and engineering marvel, @NASA 's Chandra X-ray Observatory has spent two decades (so far ) exploring the cosmos unlike any other telescope. What it has found will astound you. See the full "First Light" video on YouTube, created in collaboration with @steerfilms : #Chandra20 More: On July 23, 1999, the Space Shuttle Columbia launched into space carrying the heaviest payload ever flown. In its cargo bay was the Chandra X-ray Observatory, a first-of-its-kind telescope that would open a new window into exploring the Universe. Unlike the Hubble Space Telescope, its older cousin, Chandra detects X-rays from space instead of the kind of light that humans can see. Only a handful of decades before, scientists didn’t know objects in space gave off X-rays. Because the Earth’s atmosphere absorbs this high-energy light, people had to wait until the dawn of the Space Age to realize that space is aglow in light that invisible to our eyes. Once known, a different kind of space race emerged. The Chandra X-ray Observatory is the culmination of decades of collaboration between scientists and engineers, private and public institutions, the United States and those around the world. Two decades after its launch, Chandra remains the most powerful X-ray telescope and continues to reveal secrets about black holes, exploded stars, and the nature of the Universe itself. See for yourself what wonders Chandra has to behold. Featuring: Belinda Wilkes, Daniel Castro, Sabina Hurley, Grant Tremblay and Kimberly Arcand.

For the first time, astronomers have found two giant clusters of galaxies that are just about to collide, as reported in a new press release by RIKEN. This observation is important in understanding the formation of structure in the Universe, since large-scale structures—such as galaxies and clusters of galaxies—are thought to grow by collisions and mergers.⁣ ⁣⁣ ⁣The composite image above shows the separate galaxy clusters 1E2215 and 1E2216, located about 1.2 billion light years from Earth, captured as they enter a critical phase of merging. Chandra’s X-ray data (blue ) have been combined with a radio image from the Giant Metrewave Radio Telescope in India (red ). These images were then overlaid on an optical image from the Sloan Digital Sky Survey that shows galaxies and stars in the field of view.⁣ ⁣⁣ ⁣The discovery of 1E2215 and 1E2216 at this stage of merging has enabled astronomers to test their computer simulations of these important collisions. This new result provides evidence of a shock wave that is generated early in the merging process and travels out away from the collision in a perpendicular direction.⁣ ⁣⁣ ⁣X-ray: NASA/CXC/RIKEN/L.

#News : Does the gas in galaxy clusters flow like milk or honey? 🥛🍯 Scientists dived deep into the Coma Cluster with @NASA 's Chandra to answer that very question, expanding our understanding of the largest structures in the Universe held together by gravity! This image represents a deep dataset of the Coma galaxy cluster obtained by NASA's Chandra X-ray Observatory. Researchers have used these data to study how the hot gas in the cluster behaves, as reported in our press release. One intriguing and important aspect to study is how much viscosity, or "stickiness," the hot gas demonstrates in these cosmic giants. Galaxy clusters are comprised of individual galaxies, hot gas, and dark matter. The hot gas in Coma glows in X-ray light observed by Chandra. Seen as the purple and pink colors in this new composite image, the hot gas contains about six times more mass than all of the combined galaxies in the cluster. The galaxies appear as white in the optical part of the composite image from the Sloan Digital Sky Survey. (The unusual shape of the X-ray emission in the lower right is caused by the edges of the Chandra detectors being visible. ) (Continued in the comments… )
