MAVEN will examine the upper atmosphere of Mars in unprecedented detail. It's scheduled to launch no earlier than 1:28 p.m. EST Monday, Nov. 18, from Cape Canaveral Air Force Station in Florida....

For the first time, using NASA's Solar Terrestrial Relations Observatory, or STEREO, scientists have imaged the edge of the sun and described that transition – from which the solar wind blows. Defining the details of this...

NASA’s THEMIS mission has overturned a longstanding belief about the interaction between solar particles and Earth’s protective magnetic field. This new discovery could help scientists predict when the solar storms that can...

Jim Green gives a canned interview for the 09/19/2014 MAVEN Mars Orbit Insertion liveshots.<br/>

A mysterious anomaly in the Earth’s magnetic field that stretches from South America to Africa is spreading.

Parodying the classic sea shanty "The Wellerman," “The Solar Wind: A Heliophysics Sea Shanty” illuminates one of the primary connections between...

At the end of June 2013, NASA will launch its newest mission to watch the sun: the Interface Region Imaging Spectrograph, or IRIS. IRIS will show the lowest levels of the sun's atmosphere, the interface region, in more detail than...

This video features two model runs. One looks at a moderate coronal mass ejection (CME) from 2006. The second run examines the consequences of a large coronal mass ejection, such as The Carrington-Class CME of 1859. These...

Eclipses set the stage for historic science. NASA is taking advantage of the Aug. 21, 2017 eclipse by funding 11 ground-based scientific studies. As our scientists prepare their experiments for next week, we're looking back to an...

Far, far beyond the orbits of the planets lie the hazy outlines of the magnetic bubble in space that we call home.



This is the heliosphere, the vast bubble that is generated by the Sun’s magnetic field and...

Our sun's adolescence was stormy—and new evidence shows that these tempests may have been just the key to seeding life as we know it on Earth.

On September 30, 2014, multiple NASA observatories watched what appeared to be the beginnings of a solar eruption. A filament -- a serpentine structure consisting of dense solar material and often associated with solar eruptions...

Five years after NASA’s MAVEN spacecraft entered into orbit around Mars, data from the mission has led to the creation of a map of electric current systems in the Martian atmosphere....

We start our “Gravity Assist” virtual tour of the solar system with – where else – the Sun! Jim is joined by Project Scientist Dr. Nicky Fox of the Johns Hopkins University Applied Physics Lab to talk about our fascinating star and...

For the first time in history, a spacecraft has touched the Sun. NASA’s Parker Solar Probe has now flown through the Sun’s upper atmosphere – the corona – and sampled particles and magnetic fields there....

As the closest planet to the Sun -- and with the most oblong orbit in the solar system -- Mercury orbits through a region where the Sun’s influence is changing dramatically.



Two NASA researchers looked to...

Our sun's adolescence was cooler than today, but stormy—and new evidence shows that these tempests may have been just the key to seeding life as we know it on Earth.

In addition to monitoring weather on Earth, the GOES-R satellites will monitor weather in space caused by electromagnetic radiation and charged particles released from solar storms on the Sun. Many people rely on space weather data,...

NASA’s Voyager 2 reached the edge of the solar system in early November. <br/>

Learn about the features of the ionosphere! This little-explored region exists between space and Earth. It is home to the aurora, the international space station, a variety of satellites, and radio communication waves. We...

We are all familiar with weather on Earth, but how much do you know about weather in space? Suitable for all ages, this introduction to space weather covers vocabulary like coronal mass ejection (CME), solar wind, and solar flare....

NASA's Parker Solar Probe is heading to the Sun. Why won't the spacecraft melt?



Thermal Protection System Engineer Betsy Congdon (Johns Hopkins APL) outlines why Parker can take
