Breathtaking Solar Prominence Eruption

Video of a solar prominence eruption that produced a solar flare and a moderate proton storm. Found at YouTube from thesuntoday.

The Sun’s Loopy Rays

Thursday, May 5th, 2011

NASA’s Solar Dynamics Laboratory catches loops of light on the Sun’s surface: Cascades of spiraling magnetic loops observed in extreme ultraviolet light by SDO danced and twisted above an active region. These loops are charged particles spinning along the magnetic field lines, and thus visually revealing them. Found at YouTube from LittleSDOHMI.

Measuring The Scale Of The Universe…With Tennis & Basketballs

Wednesday, March 23rd, 2011

If the Earth were the size of a basketball and the moon a tennis ball, how far apart would they be? Diagrams that are not to scale make us think that they’re closer than they really are. Found at YouTube from 1veritasium.

Solar Eruptions

Saturday, April 24th, 2010

Via Mashable: The recently launched Solar Dynamics Observatory has been taking some unique portraits of our solar companion using four telescopes looking at the sun in different wavelengths. The results are unusual and beautiful, fulfilling the mission’s goal of exploring “solar activity in unprecedented detail.”

A Prominence Eruption Observed By AIA

AIA caught this beautiful prominence eruption only a few days after its doors were opened. The movie wobbles at the end because AIA’s image stabilization system wasn’t fully activated yet. Without the full stabilization capability, AIA would not be able to see the Sun at such high resolution. The actual wobble was extremely small – imagine a period in a newspaper seen from 100 meters away. Now move that period over a couple of words. Found at YouTube from SDOmission2009.

High-Res Throughout The Sun’s Atmosphere – AIA & HMI

This movie captures only a fraction of SDO’s imaging capabilities. It shows the Sun’s magnetic field followed by only four of SDO’s 12 imaging wavebands. You’ll see an eruption, flare, and dimming (dark regions evacuated by the eruption) by observing the event in several different layers of the atmosphere. Why didn’t we show all 12 layers at full resolution? Because at high-res the movie would nearly a third of a gigabyte in size. Found at YouTube from SDOmission2009.

Many Different Views Of The Sun – HMI & AIA

This movie starts with a magnetogram from HMI and moves on to 7 different wavebands observed by AIA’s telescopes. AIA covers a wide range of temperatures and will answer important questions about the temperature and energy structure of the Sun’s atmosphere. Found at YouTube from SDOmission2009.

The Solar Soundtrack

Sunday, March 21st, 2010

University of Michigan researchers have sonified solar wind data and created an acoustic, or musical, representation of it. The resulting music is part art, part science. Found at YouTube from futurityvideo.
