dark-energy

NASA publicly revealed its completed Roman Space Telescope on April 21 at Goddard, setting up a Falcon Heavy launch as early as this fall for a five-year survey of dark energy, exoplanets, and the galactic bulge.

The Fred Young Submillimeter Telescope, perched at 5,600 meters in Chile, inaugurated on April 9 with over 100,000 superconducting detectors and a mapping speed ten times faster than any predecessor.

A team using the Hobby-Eberly Telescope processed 600 million spectra to build the first large-scale intensity map of Lyman-alpha emissions from 9 to 11 billion years ago, exposing faint galaxies and intergalactic gas invisible to conventional surveys.
