Despite significant cost overruns, NASA's James Webb Space Telescope is now set for a March 2021 launch — assuming it receives Congressional reauthorization.
NASA officials announced Wednesday that the James Webb Space Telescope launch would be delayed until approximately May 2020. But before the mission can launch, its managers may have to face Congress.
A non-partisan government office has issued a report warning of additional delays for the James Webb Space Telescope, which could pit the mission against its funding cap.
Supermassive black holes en route to merger have strange dynamics in their gas disks. Astronomers have spotted the most distant spectroscopically confirmed supernova. And NSF decides the fate of the Arecibo Observatory.
A new telescope called the SkyMapper has charted stars and galaxies across the southern sky, producing a map called "the best ever created."
The U.S. National Science Foundation will continue to fund the iconic radio dish, though at a much-reduced level, as it seeks partners to share in the facility's operation.
The Zwicky Transient Facility has taken its first image, covering an area equivalent to 247 full Moons in a single shot. This beginning is part of an ongoing sea change in astronomy.
A professional observatory in Greece has begun recording flashes created when bits of interplanetary debris strike the Moon.
The long-awaited James Webb Space Telescope — the successor to the Hubble Space Telescope — has slipped its launch date by several months. It will now launch between March and June 2019.
