VIDEO GALLERY
- SDO Mission video on YouTube
- This short video (1:30) briefly describes the goal of the SDO mission and why it is important that we continue to observe the sun.
- Sentinels of the Heliosphere
- This visualization tours the regions of near-Earth orbit; the Earth's magnetosphere, sometimes called geospace; the region between the Earth and the Sun; and finally out beyond Pluto, where Voyager 1 and 2 are exploring the boundary between the Sun and the rest of our Milky Way galaxy.
- Introduction to the STEREO Mission
- When the Solar Terrestrial Relations Observatory (STEREO) launches in Summer 2006, scientists expect to gain a better understanding of solar storms and improve warning times for everyone from satellite operators to astronauts.
- "Blackout: The Sun-Earth Connection" (Part 1 of 4)
- "Blackout" takes you on a journey from the Sun to the Earth as eruptions known as solar storms travel to Earth and effect our lives in ways we still don't completely understand. 3-D animations bring to life the journey, through 150 million kilometers of space, of these outbursts of "space weather".

NASA Fact
Earth's magnetic poles reverse their geographic locations every 300,000 years. The last event happened 780,000 years ago.
