Dark Energy is what we call the mysterious force that seems to be pushing the universe apart. By some calculations, it makes up 70% of everything in nature. Or...maybe it doesn’t exist at all! Plus, Juno’s observations give us new...

A new model has been able to predict solar flares with up to about 20 hours of warning, and our galaxy is farting blobs of cold gas inside the Fermi Bubbles!

In 1999, scientists discovered something that took over 20 years to solve. Why do solar flares move like a lava lamp?

NASA's Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites (TRACERS) mission will study "magnetic reconnection and its effects in Earth's atmosphere," according to the Goddard Space Flight Center....

What Parker Solar Probe Heard Around the Sun.

Spacecraft near Earth have long relied on GPS signals for navigation, just as users on the ground might use their phones to navigate the highways. Farther away, navigation — and the math behind it — becomes a great deal more challenging.

Our virtual tour of the solar system continues with Mercury, the closest planet to the Sun. Since it’s tough to observe Mercury except at dawn or twilight, most of what we know about Mercury is from NASA’s Mariner 10 and MESSENGER missions.

Like sending sensors up into a hurricane, NASA has flown four spacecraft through an invisible maelstrom in space, called magnetic reconnection. Magnetic reconnection is one of the prime drivers of space radiation and so it is a key...

Scientist John Dorelli explains the MMS mission's orbit and why the four spacecraft fly in a tetrahedron formation. This complex arrangement enables scientists to gather data about magnetic reconnection in 3D.



On its...

Host Katrina Jackson talks with Craig Pollock and Ulrik Gliese about Goddard's contribution to the Magnetospheric Multiscale mission - the Fast Plasma Investigation suite of instruments. These instruments will study a...

Two NASA spacecraft have provided the most comprehensive movie ever of a mysterious process at the heart of all explosions on the sun: magnetic reconnection.



Magnetic reconnection happens when magnetic field lines...

This short video features commentary by David Sibeck, project scientist for the THEMIS mission, discussing a visualization of reconnecti

on fronts.

Taking advantage of an...

Senior Project Scientist Tom Moore outlines the three instrument suites onboard the four MMS spacecraft.



On March 12, 2015, NASA plans to launch the Magnetospheric Multiscale, or MMS, mission. MMS consists of four...

It's hard enough to build one spacecraft, but the Magnetospheric Multiscale Mission (MMS) is building four. Together, the spacecraft will unlock the mysteries of magnetic reconnection, when magnetic fields explosively connect and...

NASA Scientist Dr. Holly Gilbert discusses the upcoming launch and overview of the MMS Mission.<b<b<br/>r/>r/>

In March 2015, NASA will launch four identical spacecraft to study how magnetic fields around Earth connect and disconnect, explosively releasing energy -- a process known as magnetic reconnection.



The Magnetospheric...

Scientists from Durham University in the United Kingdom and NASA now propose that a universal mechanism can explain the whole spectrum of solar eruptions. They used 3-D computer simulations to demonstrate that a variety of eruptions...

Though close to home, the space immediately around Earth is full of hidden secrets and invisible processes. In a new discovery reported in the journal Nature, scientists working with NASA’s Magnetospheric...

This video provides an overview of solar flares, explaining how they occur and their impact on Earth. It highlights the immense energy released during a solar flare and the various emissions it produces. The video also discusses the...
