By Mara Johnson-Groh NASA's Goddard Space Flight Center Recently, NASA's Magnetospheric Multiscale mission — MMS — was in just the right place at the right time to observe a new kind of turbulent particle jet in near-Earth space. The particle jet streamed from a particularly turbulent region called the magnetosheath, just outside the outer boundary of …
By Steele Hill NASA's Goddard Space Flight Center On Sept 9-10, NASA's Solar Dynamics Observatory witnessed a double lunar transit, when the Moon passed between the SDO spacecraft and the Sun twice in just a few hours. But did you know that the Earth can also get in the way? Here's how Earth and Lunar …
By Lina Tran and Miles Hatfield NASA's Goddard Space Flight Center NASA's STEREO spacecraft watches the Sun 24/7 — but the Sun it sees is not the one you and I see. STEREO can see the Sun's corona, or outer atmosphere. The only time we can see the corona from Earth with the naked eye …
