NASA | Many Views of a Massive CME

Показать описание
On July 23, 2012, a massive cloud of solar material erupted off the sun's right side, zooming out into space. It soon passed one of NASA's Solar Terrestrial Relations Observatory, or STEREO, spacecraft, which clocked the CME as traveling between 1,800 and 2,200 miles per second as it left the sun. This was the fastest CME ever observed by STEREO.
Two other observatories – NASA's Solar Dynamics Observatory and the joint European Space Agency/NASA Solar and Heliospheric Observatory -- witnessed the eruption as well. The July 2012 CME didn't move toward Earth, but watching an unusually strong CME like this gives scientists an opportunity to observe how these events originate and travel through space.
STEREO's unique viewpoint from the sides of the sun combined with the other two observatories watching from closer to Earth helped scientists create models of the entire July 2012 event. They learned that an earlier, smaller CME helped clear the path for the larger event, thus contributing to its unusual speed.
Such data helps advance our understanding of what causes CMEs and improves modeling of similar CMEs that could be Earth-directed.

Moving so fast it passed all the preceding CME's!

This would have fried our electronics ...

I wonder what humans will do to survive when one of these hits earth and sends us back to the time before ben franklin invented electricity

How many times can I say WOW before I sound stupid? The pictures and numbers are just jaw-dropping. Our ability to see and understand such amazing events makes all the expense and hard work at NASA etc. worthwhile.

I wanna know if strong CME's influence our behavior. In other word's, can the radiation from a strong CME drive us crazy for a short period of time.

I’m reading a cool novel called Solar Flare right now and it’s a “what if” scenario book. And it was published 25 years ago. Scary potential

Very interesting and educational.. Thank you!

Isn’t this the same year the Mayans predicted would be the end of the world?

Maybe a good idea to start practicing shutdowns and reboots instead of just firedrills huh

5-9-24 earth is facing multiple X class flares 4 of which are currently earth directed.

If a CME is a solar storm than its intensity would be determined not just by the size of its mass but also its density and pressure. If this is true does that mean a smaller focused CME with a dense mass and high velocity could do more damage than a CME of larger mass that's slower and less dense?

thank you to NASA, your video is beautiful :)

Unbelievable science. Stereo A and B are a much better investment than manned spaceflight.

What is the music that is used in this? I can not find anything about it. I went to their website. Did a search on line....  Found nothing....

Was this the solar outburst which eventually reached Voyager I, by which we could detect Voyager I had left the solar system?

relative to carrington [estimate], how big? guess the mayans were almost correct ... lol
