NASA Sounding Rocket Finds Helium Structures in Sun’s Atmosphere

08.07.2020
Helium is the second most abundant element in the universe after hydrogen. But scientists aren’t sure just how much there actually is in the Sun’s atmosphere. NASA's HERSCHEL sounding rocket has taken the first global measurements of helium in the extended solar atmosphere – a key piece of information for understanding our space environment.

NASA Sun Data Helps New Model Predict Big Solar Flares

07.31.2020
Using data from NASA’s Solar Dynamics Observatory, or SDO, scientists have developed a new model that successfully predicted seven of the Sun’s biggest flares from the last solar cycle, out of a set of nine. With more development, the model could be used to one day inform forecasts of these intense bursts of solar radiation.

NASA’s AIM Spots First Arctic Noctilucent Clouds of the Season

05.28.2020
Ice-blue clouds are drifting high above the Arctic, which means the Northern Hemisphere’s noctilucent cloud season is here. NASA’s AIM spacecraft first spotted wisps of these noctilucent, or night-shining, clouds over the Arctic on May 17.

Why ESA and NASA's SOHO Spacecraft Spots So Many Comets

05.19.2020
The Solar and Heliospheric Observatory, a joint mission between ESA (European Space Agency) and NASA, was not designed to find comets, but it has discovered well over half of all known comets, with nearly 4,000 comets found.
