Russia’s space agency has announced its intention to unilaterally seize control of a German telescope mounted to a Russian-built spacecraft. It’s a terrible, irresponsible idea, as even Russian scientists will admit. Read...
Long before Webb even launched from French Guiana, we’ve been waiting for this moment: the first full-color images from this cutting-edge space telescope. NASA announced yesterday that those pictures will be available on July 12, along with some spectroscopic data. Read...
While some look up to the sky and see humankind’s future, astronomers look up with hope to see further back in time than ever before. New telescopes under construction around the world (and one already in space) are setting the stage for a new age in astronomy, one that we hope will reveal how...
A major milestone in the commissioning of the James Webb Space Telescope has been met, as engineers continue to bring the observatory’s view of the universe into focus. Read...

A major milestone has been achieved in the deployment of the James Webb Space Telescope, with an onboard instrument detecting its first photons from a distant star. This means engineers can now begin the three-month process of aligning the space telescope’s 18 mirrors. Read...
The left wing of Webb’s primary mirror unfolded and locked into position on Saturday, in what was the final step of the major deployments phase. The space telescope finally looks like a telescope, but the commissioning phase is far from over. Read...
The James Webb Space Telescope has successfully deployed the tripod that holds the observatory’s secondary mirror, in what is a critical milestone for the mission. Read...

On the night of November 23, 2014, a powerful telescope on Mauna Kea in Hawaii was trying to pick out the enigmatic movements of a black hole traveling through space. In the seven hours the telescope peered at the cosmos, it may have caught one, as a structure about the size of Earth eclipsed a...
