Imagine peering into the heart of a galaxy millions of light-years away, watching stars explode, black holes grow, and galaxies collide. That's exactly what the Chandra X-ray Observatory allows us to do. Launched by NASA in 1999, Chandra is the most powerful X-ray telescope in the world. Its unique ability to see X-rays, a type of invisible light, lets us explore parts of the universe that ordinary telescopes can’t reach.

Named after renowned physicist Subrahmanyan Chandrasekhar, Chandra has given us insight into the hottest, most energetic parts of space. It’s uncovered secrets about black holes, the life cycle of stars, and even evidence of dark matter. Without it, many of the universe’s most powerful phenomena would remain invisible to us.

But there’s a risk that Chandra could be shut down, mainly due to funding challenges. If this happens, the world would lose one of its most advanced tools for exploring the high-energy universe. A shutdown would mean fewer opportunities to study cosmic mysteries and a major gap in our understanding of black holes, dark matter, and the origins of galaxies.

Chandra has given us a rare window into the invisible universe. Losing it would be more than just retiring a telescope; it would close the door on discoveries that could reshape our understanding of space. So help us save Chandra. Visit savechandra.org to learn more how you can help.
