On March 30, 2019, Parker Solar Probe begins the second solar encounter phase of its mission, culminating in its closest approach to the Sun, called perihelion, on April 4 at 6:40 p.m. EDT.
By Sarah Frazier NASA's Goddard Space Flight Center On March 6, 2019, our Solar Dynamics Observatory, or SDO, witnessed a lunar transit — where both the Sun and Moon displayed a little odd behavior. First, there was the transit itself. A lunar transit occurs when the Moon passes between SDO and the Sun, blocking the …
By Tom Bridgman, Ph.D. NASA's Goddard Space Flight Center Scientific Visualization Studio In my nearly 20 years making visualizations at NASA's Scientific Visualization Studio, "Argo Sun"— a simultaneous view of the Sun in various wavelengths of light — is probably one of my favorites. It is not only scientifically useful, but it's one of the …
By Steele Hill NASA's Goddard Space Flight Center NASA's Sun-observing spacecraft produce some pretty breathtaking images of our star — everything from detailed closeups of its surface, to wide-field views of its expansive outer atmosphere. But on occasion, the acrobatics of light that can produce some odd photographic effects. …
by Ellen Gray Excitement was in the air when research scientist Dan Slayback of NASA's Goddard Space Flight Center in Greenbelt, Maryland, approached a small trio of islands in the South Pacific island nation of Tonga. It was October 8th, and Dan had joined the scientists and students with the Sea Education Association's SEA Semester …
NASA's Parker Solar Probe has begun the second of 24 planned orbits, on track for its second perihelion, or closest approach to the Sun, on April 4, 2019.
By Susannah Darling NASA Headquarters On December 3rd, 2018 the second Miniature X-Ray Solar Spectrometer, MinXSS-2, was launched. MinXSS-2 is a NASA CubeSat designed to study the soft X-ray photons that burst from the Sun during solar flares. Along the way, it may answer a long-standing mystery of what heats up the Sun's atmosphere, the …
By Corey Walker / NASA ARMSTRONG FLIGHT RESEARCH CENTER, PALMDALE, CALIFORNIA / My name is Corey Walker. One of the most incredible things I've done on paper is become a NASA intern through the agency's Student Airborne Research Program, otherwise known as SARP. Why? I grew up in Etowah County, Alabama which has a poverty …
The New Horizons spacecraft is healthy and on final approach to explore Ultima Thule in the Kuiper Belt. On New Year's Eve and New Year's Day, New Horizons will swoop three times closer to "Ultima" than we flew past Pluto! On Saturday, Dec. 15, the New Horizons hazard watch team concluded its work, having found …
By Mara Johnson-Groh NASA's Goddard Space Flight Center Space isn't silent. It's abuzz with charged particles that — with the right tools — we can hear. Which is exactly what NASA scientists with the Van Allen Probes mission are doing. The sounds recorded by the mission are helping scientists better understand the dynamic space environment …
