Only a month into a new observing run, gravitational-wave observatories have announced five new signals — one of which could turn out to be a black hole swallowing a neutron star.
A vision from 70 years ago, the Zwicky Transient Facility has produced a wave of discoveries — but it’s only a hint of what’s to come.
After a 10-day lockdown to cooperate with a criminal investigation, Sunspot Solar Observatory is back to looking at the Sun.
The famed Arecibo Observatory has faced down several funding challenges in recent years, and a hurricane to boot, but now a new project is making the radio dish more relevant to astronomy than ever.
Despite significant cost overruns, NASA's James Webb Space Telescope is now set for a March 2021 launch — assuming it receives Congressional reauthorization.
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.
