INCREDIBLE... Photos of the Sun

[jackovesk]

Lunar Transit
The dark moon passes between the Sun and imaging equipment aboard NASA's Solar Dynamics Observatory (SDO) spacecraft, creating a partial eclipse. Launched on February 11, 2010, the orbiter will observe the Sun for the next five years, providing scientists with a better understanding of how the Sun affects the Earth's atmospheric chemistry and climate.



Ring of Fire
A dense cloud of loop-shaped gas erupts from the Sun's surface. Solar prominences, as this occurrence is called, can loop thousands of miles into space and can persist in the Sun's corona for several months. The largest known prominence, an extension over 430,000 miles — roughly equivalent to the star's radius — was observed in 2010.



Sunspots
The dark areas are caused by intense magnetic activity that create areas of reduced surface temperature. Sunspots expand and contract as they travel at a few hundred miles per second across the surface of the Sun. They can be as large as 50,000 miles in diameter, making them at times visible to the naked eye from Earth.



Silhouette
The Space Shuttle Atlantis transits the Sun during its 30th mission. This photo was taken from the Kennedy Space Center before the last servicing mission to the Hubble Space Telescope.



Shining Star
Former NASA astronaut Joseph Tanner is photogrtaphed during a spacewalk outside the Space Shuttle Discovery in low Earth orbit during the second servicing mission of the Hubble Space Telescope. The Sun is visible behind him. Even when the Sun is shining, the sky appears dark in low Earth orbit, because there isn't enough atmosphere to diffuse sunlight.



Loops of Plasma
Anchored in the photosphere, these coronal loops measure up to 60,000 miles and can be observed between the lower corona and the transition region of the Sun. Flowing along the magnetic field, the arches begin to rise when the plasma heats up, and crash down when it cools at more than 60 miles per second. Scientists have recently suggested that they heat the corona to temperatures about 300 times the sun's surface.



Jet Streams
Spicules, above, rise from the Sun's interior to its chromosphere at a supersonic jet speed of over 30,000 miles per hour. At any given time, there are more than 60,000 spicules active on the Sun. They have a lifespan of about 5 minutes.

WOW what awesome photos/ and they teach us it is just a big heater...such illusion to this majestic body of information!

Just the fact we could look at those pictures and see wonders, makes us special.
Thanks for posting .

Hey Jack.
how about those pictures with whatever (Earth size oblects ) floating around the sun. do you have those you can post?
Thanks

Sorry Mate...

You are only allowed to have 7 pictures per post, these are the last 2 in the collection.



Sunrise
The Sun emerges in the distant horizon as it rises above Earth.



360 Degree View
Based on high resolution data collected by NASA's two twin Solar Terrestrial Relations Observatory (STEREO) probes, this photo shows two halves of the star taken from opposite sides of the Sun. The photos are part of a NASA program that provides a 360-degree view of the solar activity.

Awesome.

Thanks Jackovesk!

Love the jetstream and loops of plasma photos!

[Nat_Lee]

What a beauty !

The only thing is I had to put my sunglases insite to look at the pics !
lol....

Thanks for the pics jackovesk !

G'day,

Thanks for these, really impressive.

I wonder if we got a bit of interference yesterday, my virginbroadband wireless modem dropped out and I could not get back on the internet for over 5 hours.

I had logged on to Avalon and couldn't get back in to log off, Pissed me off no end. Either that or you know who was playing funny buggers (LOL).

Monster Prominence Erupts from the Sun

When a rather large M 3.6 class flare occurred near the edge of the Sun on Feb. 24, 2011, it blew out a gorgeous, waving mass of erupting plasma that swirled and twisted for 90 minutes.
NASA’s Solar Dynamics Observatory captured the event in extreme ultraviolet light. Because SDO images are high definition, the team was able to zoom in on the flare and still see exquisite details.
And using a cadence of a frame taken every 24 seconds, the sense of motion is, by all appearances, seamless.


I was looking at this earlier today, Nice little 16 sec video.

John101,

I think you meen this link

[John101]

Seems to be a problem getting the right video to link. it's not the one you posted either

I see it is posted here now anyway.
