Chandra spotted a 300,000-light-year jet from a distant quasar. But amid this breakthrough, the telescope now faces defunding, threatening the future of U.S. X-ray astronomy.

“If you go to our sun, you have 15-million- [degree] temperatures,” Schweda explained. “The hottest stars [are] 100 million.
