Venus is disappearing from the evening sky — here’s how to see it while you can

NeRD

Soon, the sky’s most glamorous evening performer will take its leave. Since late March, Venus has been the unmistakable “Evening Star,” gleaming shortly after sunset and stealing attention from nearly everything else in the twilight. In June, it helped stage a striking three-planet lineup after sundown, outshining both Jupiter and Mercury. Now the curtain is beginning to fall: Venus is sinking night by night and will trade its evening role for a morning one before October is over. A familiar dance around the sun Venus moves to a remarkably regular…

Scientists detect signals of hydrogen from billions of years ago. Could this help us map out the universe?

NeRD

Astronomers have used the MeerKAT radio telescope to detect hydrogen gas billions of light-years away from us — from a period when the cosmos was billions of years younger than its current age of 13.8 billion years. The research may provide astronomers with a new way of mapping the large-scale structure of the universe. The technique would rely on charting out where hydrogen, the universe’s lightest and most abundant element, is located across the cosmos. It’s known as hydrogen intensity mapping. Neutral hydrogen emits a faint radio signal that astronomers…

NASA Ames Fire Department Aircraft Firefighting Training

NeRD

The fire department at NASA’s Ames Research Center in California’s Silicon Valley will perform training on the Moffett Federal Airfield beginning Tuesday, Sept. 8 through Friday, Sept. 11. The training will involve the use of a propane-fueled aircraft fire simulator and be conducted from 8 a.m. to 8 p.m. PDT. Because the aircraft simulator is fueled by propane, very little smoke should be produced during the controlled training fires. However, flames may be visible to drivers on U.S. Highway 101. The training is intended to prepare Ames’ first responders to…

NASA Hosts Virtual Artemis Webinar for Blind, Low-Vision Community

NeRD

Two technicians at NASA’s Michoud Assembly Facility in New Orleans stand around one of the four RS-25 engines for the agency’s SLS (Space Launch System) rocket on Sept. 8, 2023. The RS-25 engine looks like a bell-shaped nozzle attached to a network of pipes. The engine is being lifted by the horizontal engine installer so it appears to be lying on its side. The RS-25 engine is about the size of a large pickup truck. The technicians are wearing hard hats and safety harnesses. Credit: NASA/Michael Democker NASA will host…

Venus is seen as it disappears behind the Moon at the start of the occultation on June 17, 2026, from the Mary W. Jackson NASA Headquarters building in Washington NASA/Joel Kowsky On Wednesday, June 17, skywatchers across the United States—and parts of Canada—enjoyed a rare event: a daytime lunar occultation of Venus. A lunar occultation occurs when the Moon moves directly in front of another celestial object from our viewpoint on Earth, briefly hiding it from sight. This time, the Moon slipped in front of Venus for the first of…
