Our “X-ray universe” refers to the Universe as observed with telescopes designed to detect X-rays. X-rays are produced in the cosmos when matter is heated to millions of degrees. Such temperatures occur where high magnetic fields, extreme gravity, or explosive forces, hold sway. Come visit your exciting X-ray Universe with Chandra!

Chandra is part of a rich legacy of telescopes. Its X-ray lineage stretches back to the Space Age when scientists and engineers pioneered instruments that were sent above the Earth’s atmosphere. In its more than 20 years of operation, Chandra and X-ray astronomy as a whole have played a pivotal role in uncovering and solving the mysteries of the Universe.

Chandra and other X-ray telescopes focus on the high-energy action and drama of the turbulent, multimillion degree outer atmospheres and gale-force outflows of gas from hot, luminous stars. Westerlund 2 is a cluster of young stars-about one to two million years old - located about 20,000 light years from Earth. It contains some of the hottest, brightest, and most massive stars known.
