Telescopes

WASHINGTON : The detection of a highly compact galaxy that formed relatively soon after the Big Bang and displayed an impressive rate of star formation is the latest example of how the James Webb Space Telescope is reshaping our…

Researchers have developed a new way to produce and shape large, high-quality mirrors that are much thinner than the primary mirrors previously used for telescopes deployed in space. The resulting mirrors are flexible enough to be rolled up…

Using ESO's Very Large Telescope (VLT), two teams of astronomers have observed the aftermath of the collision between NASA's Double Asteroid Redirection Test (DART) spacecraft and the asteroid Dimorphos. The controlled impact was a test of…

Some of the largest and most sophisticated telescopes ever made are under construction at the Simons Observatory in Northern Chile. They are designed to measure cosmic microwave background -- electromagnetic radiation left over from the…

Researchers have developed a new way to use femtosecond laser pulses to fabricate the high-precision ultrathin mirrors required for high-performance x-ray telescopes. The technique could help improve the space-based x-ray telescopes used to…

<!-- -->DART mission was the world's first-ever in-space test for planetary defence.Two of NASA's space telescopes - James Webb Space Telescope and Hubble Space Telescope - have captured views of the DART spacecraft intentionally…
