NASA Unveils Unimaginable Cosmic Views As Chandra X-Ray Observatory Celebrates 20 Years
It's been 20 years since NASA's X-ray Chandra Observatory was launched to offer us the sharpest view ever seen on X-rays – and the telescope continues to be working on the frontier of science, mentioned the # 39; company.
The observatory, dubbed the identify of the late Subrahmanyan Chandrasekhar, American Indian astrophysicist, was launched on July 23, 1999. He climbed into house aboard the Columbia shuttle. Since then, he has been circling the Earth and watching the sky. To commemorate this nice anniversary, NASA not too long ago launched six new pictures of Chandra, illustrating every little thing from the sunshine of the nascent stars to the construction of huge clusters of galaxies.
"Chandra is unmatched in her capability to seek out and examine X-ray sources," mentioned Belinda Wilkes, director of Chandra's X-ray heart, in a press release. "Since just about all astronomical sources emit X-rays, we want a telescope like Chandra to totally visualize and perceive our universe."

Chandra's mission has developed with our understanding of house. At its launch twenty years in the past, solely a handful of exoplanets had been recognized. Right this moment, Chandra repeatedly evaluations how star radiation impacts planets in orbit. Gravitational waves (large ripples in space-time) had been solely concept in 1999, however Chandra now observes the results of black gap mergers and different occasions that produce them.
The telescope can also be engaged in observations that haven’t but taken place, just like the examine of darkish vitality, a poorly understood phenomenon, which might represent an excellent a part of our universe.
Chandra's concept dates again greater than 40 years, based on the preliminary proposal of Riccardo Giacconi and Harvey Tananbaum in 1976. Giacconi acquired the 2002 Nobel Prize in Physics due to his contribution to X-ray astronomy. Tananbaum was the primary director of the Chandra X-Ray Heart, which operates the instrument.
The telescope is working properly right now after overcoming a gyro downside by the tip of 2018. It’s anticipated to proceed operations for at the least 2024 hours, with the potential for two contract choices of three years in a row.
