NASA’s Parker Solar Probe Hears Whispers Of Solar Wind

Streams of plasma from the sun create “chirping” and “whistling” noises, and NASA’s Parker Solar Probe can hear them. The solar wind is a stream of charged particles released from the sun’s upper atmosphere, also known as the corona. This plasma consists of electrons, protons and other charged particles that flow from the sun’s atmosphereContinue reading NASA’s Parker Solar Probe Hears Whispers Of Solar Wind

These twin rovers might explore the moon together one day

Astronauts aren’t the only ones who will have to work together on future crewed missions. As humans work toward returning to the moon with initiatives such as NASA‘s Artemis program, which aims to land the first woman and the next man on the moon by 2024, researchers are developing the robots that will explore withContinue reading These twin rovers might explore the moon together one day

2 satellites will narrowly avoid colliding over Pittsburgh on Wednesday

Two defunct satellites will zip past each other at 32,800 mph (14.7 kilometers per second) in the sky over Pittsburgh on Wednesday evening (Jan. 29). If the two satellites were to collide, the debris could endanger spacecraft around the planet. It will be a near miss: LeoLabs, the satellite-tracking company that made the prediction, saidContinue reading 2 satellites will narrowly avoid colliding over Pittsburgh on Wednesday

How Earth Climate Models Help Scientists Picture Life On Unimaginable Worlds

In a generic brick building on the northwestern edge of NASA’s Goddard Space Flight Center campus in Greenbelt, Maryland, thousands of computers packed in racks the size of vending machines hum in a deafening chorus of data crunching. Day and night, they spit out 7 quadrillion calculations per second. These machines collectively are known asContinue reading How Earth Climate Models Help Scientists Picture Life On Unimaginable Worlds

Bipartisan House Bill Spurns 2024 Moon Landing Goal, Favoring Focus On Mars

A NASA authorization bill released by the House Science Committee Friday proposes major changes to the direction of the agency’s human spaceflight programs, with a goal to land crews on the moon by 2028, not the 2024 schedule set by the Trump administration. The bipartisan legislation would appear to stand in the way of anyContinue reading Bipartisan House Bill Spurns 2024 Moon Landing Goal, Favoring Focus On Mars

NASA’s Kepler Witnesses Vampire Star System Undergoing Super-Outburst

NASA’s Kepler spacecraft was designed to find exoplanets by looking for stars that dim as a planet crosses the star’s face. Fortuitously, the same design makes it ideal for spotting other astronomical transients – objects that brighten or dim over time. A new search of Kepler archival data has uncovered an unusual super-outburst from aContinue reading NASA’s Kepler Witnesses Vampire Star System Undergoing Super-Outburst
