Developing telescope mirrors in new way could sharpen our view of black holes, new stars
Researchers have created a new method for fabricating the high-precision, ultrathin mirrors needed for high-performance x-ray telescopes using femtosecond laser pulses. The method might assist advance the capabilities of space-based x-ray telescopes that are used to observe high-energy cosmic phenomena like the formation of supermassive black holes and new stars.
