Vera C. Rubin Observatory begins largest cosmic survey

Kiswahili

The Vera C. Rubin Observatory in Chile has started the Legacy Survey of Space and Time, set to create the most detailed record of the universe ever made.

The observatory completed a year of testing and calibration before launching the decade-long project. It will gather around 10 terabytes of data each night through hundreds of high-resolution images.

Each image covers an area roughly 40 times the size of the full moon and focuses on the southern sky. Early alerts from the system have already identified more than 11,000 new asteroids.

Brian Stone of the US National Science Foundation said, “Today, we begin filming the greatest cosmic movie ever made.” The data will support studies of solar system objects, the Milky Way, and distant cosmic phenomena including dark matter and dark energy.

NASA's Artemis II crew became the first humans in over 50 years to loop around the moon's far side on April 6, traveling farther from Earth than any before them. The astronauts captured unprecedented views, including close-ups of craters and a unique solar eclipse. They are now heading back for a splashdown off California on April 10.

DESI completes largest 3D map of 47 million galaxies and quasars ahead of schedule

The Dark Energy Spectroscopic Instrument (DESI) at Kitt Peak National Observatory has finished its five-year sky survey ahead of schedule, capturing spectra from 47 million galaxies and quasars—six times more than all previous surveys combined—plus 20 million stars. This creates the most detailed high-resolution 3D map of the universe to date, exceeding initial goals of 34 million objects and offering new insights into cosmic structure and potentially weakening dark energy.
