IBEX is a new NASA mission that will study the interaction between the solar wind and the material beyond our Solar System called the interstellar medium. The solar wind flowing out of the sun inflates a bubble that we call the...

Every object, planet or person traveling through space has to contend with the Sun's damaging radiation -- and the Moon has the scars to prove it. Research using data from NASA's ARTEMIS mission — short for Acceleration, Reconnection,...

NASA's Parker Solar Probe mission has returned unprecedented data from near the Sun, culminating in new discoveries published on Dec. 4, 2019, in the journal Nature. Among the findings are new understandings of how the Sun's constant...

The atmosphere is dynamic and forever changing to maintain balance. The ingredients of air, sunlight and water allow life to exist on Earth, but they also generate calm scenes like rainbows, as a tornado ends. All storms move moisture,...

NASA’s Parker Solar Probe has taken its first visible light images of the surface of Venus from space. Smothered in thick clouds, Venus’ surface is usually shrouded from sight. But in two recent flybys of the planet, Parker used its...

A countdown of the top 5 solar discoveries from the Sun-Earth Connection Education Forum. These include the discoveries of sunspots, the solar cycle, the heliosphere, aurora formation, and space weather. An introduction plus Number 5 in...

Since February 2011, the two spacecraft of NASA's the Solar Terrestrial Relations Observatory or STEREO mission have been providing scientists with unprecedented views of the far side of the sun. The spacecraft travel at different...

Humans have always wanted to learn about the Sun, but our understanding of our favorite star has changed through the centuries. In prepartion for Sun360, when the STEREO spacecrafts will provide the first uninterrupted view of the Sun,...

Where does the solar system end? It all depends on the criteria you are using. Based on where the planets end, you could say it's Neptune and the Kuiper Belt. If you measure by edge of the sun's magnetic fields, the end is the...

This live-action video program is about the word revolution. The program is designed to reinforce and support a student's comprehension and retention of the word revolution through use of video footage, photographs, diagrams and...

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 boundary helps...

This version of SDO:Three Years in Three Minutes is extended and narrated by NASA's Goddard Space Flight Center heliophysicist Alex Young. He highlights many interesting aspects of the video and points out several of the single-frame...

On March 20, 2009, at 1:00 p.m. EDT, join a panel of scientists for a live Sun-Earth Day Webcast on www.nasa.gov and NASA TV. During the webcast, scientists will share discoveries about the sun, while students monitor the sun and prepare...

Launched in October 2006, STEREO traces the flow of energy and matter from the sun to Earth. It also provides unique and revolutionary views of the sun-Earth system. STEREO, when paired with SDO, can now give us the first complete view...

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 disrupt power...

On March 20th, 2015, the Moon’s shadow will create a total solar eclipse. This video presents several visualizations of what this shadow would look like from space, and highlights the areas of the world in the path of the umbra and...

Dean Pesnell, the SDO Project Scientist, explains how the the Extreme Ultraviolet Variability Experiment (EVE) instrument will allow us to better measure solar irradiance in extreme ultraviolet wavelengths. This type of irradiance, which...

IBEX is a new NASA mission that will study the interaction between the solar wind and the material beyond our solar system called the interstellar medium. The solar wind flowing out from the sun inflates a bubble that we call the...

NASA’s Ionospheric Connection Explorer, or ICON, launches in December 2017 [Ed. note: the launch date has subsequently been scheduled for Nov. 7, 2018] and orbits above the upper atmosphere, through the bottom edge of near-Earth space....

Our Cold War history is now offering scientists a chance to better understand the complex space system that surrounds us. Space weather -- which can include changes in Earth's magnetic environment -- are usually triggered by the sun's...

Early in the morning of Nov. 7, 2018, NASA launches the Ionospheric Connection Explorer, or ICON, a spacecraft that will explore the dynamic region where Earth meets space. ICON launches on a Northrop Grumman Pegasus XL rocket, which is...

Dean Pesnell, the SDO Project Scientist, explains how the Helioseismic and Magnetic Imager (HMI) instrument will allow us to see activity inside the sun and even on the other side of the sun. This video is available for download from the...

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 has...

We are going forward to the Moon by 2024, but did you know that back in 2005, Dr. Jim Garvin and his team of scientists pointed the Hubble Space Telescope at our nearest celestial neighbor for a very important reason? The Hubble team...
