A Backyard View of a Solar Prominence

An enormous tree-shaped prominence spreads its “branches” tens of thousands of miles above the Sun’s photosphere in this image, a section of a photo acquired in hydrogen alpha (Ha) by Alan Friedman last week from his backyard in Buffalo, NY. Writes Alan on his blog, “gotta love a sunny day in November!” Check out the full image…

A Solar “Danse Macabre”

NASA’s Solar Dynamics Observatory captured a video on March 27 – 28 showing two large areas of “dark” plasma on the Sun’s limb, twisting and spiraling in our star’s complex magnetic field. The southern region bears an uncanny resemblance to three figures swaying to some spooky, unheard music… a real “danse macabre” on the Sun! Watch the…

A Tall Tale of a Prominent Figure

Taken on July 29, 2010, this hydrogen-alpha-light photo by Alan Friedman shows a delicate, wispy solar prominence stretching more than 200,000 miles from the Sun’s limb… nearly as far as the distance from Earth to the Moon! This photo was taken with Alan’s backyard telescope from his location in Buffalo, NY. Many of his solar photos…

SDO: Year One

Can’t see the video below? Click here. One year ago today, on April 21, 2010, NASA held a First Light press conference where the first images from the Solar Dynamics Observatory were presented to the public! Now here we are one year later and the images and video we have enjoyed these past 12 months…

Afternoon Delight

I spotted this on the SDO site late this afternoon…it shows an eruption of plasma from the Sun’s photosphere that stretches out many tens of thousands of miles…the Earth could easily fit many times over beneath the looping structure! This image is from about 5pm EDT (21:59 UT), and shows the eastern limb of the Sun,…

Detachable Prominence

Here’s the latest image of the Sun from photographer Alan Friedman, showing incredible surface detail as well as the remnants of a detached prominence that had erupted from active region 1166 on March 3, 2011. This image was taken during a Winter Star Party event in West Summerland Key, Florida. “A close-up look at the…

A Transient Transit

Almost forgotten today in all the excitement over the giant prominence seen by SDO, the Moon also had a small role to play over the weekend: its lunar transit of the Sun in front of SDO’s cameras! Although brief and not captured by all the AIA instruments, AIA 304 did manage to glimpse a peek…

Monster Sun

Everyone’s abuzz about what SDO is watching this morning: a huge solar prominence and filament wrapping partway around the southwestern hemisphere of the Sun, literally hundreds of thousands of miles long! This is a section of the latest image from SDO’s Atmospheric Imaging Assembly (AIA) 304 camera, which best captures details about the sun’s outer…

Flare Up

I caught this image this morning on the SDO site…it shows an eruption of plasma from the Sun’s photosphere that stretches out several tens of thousands of miles…the hooked loop at the end could easily encircle the entire Earth! This image is from about 11am or so, within a couple of hours the structure had…

A Pair of Flares

  A twisting pair of prominences erupt almost 50,000 miles above the surface of the sun in this image from SDO, taken today, October 21, 2010. This is a composite of two imaging wavelength filter images (AIA 304 and 171), combined to show surface (photosphere) detail as well as lower atmosphere (chromosphere) detail. The scale…

Prominence Earth

A serpentine solar prominence snakes thousands of miles through space towards an unsuspecting Earth! This apocalyptic sci-fi scene is made up of two combined images of the sun from NASA’s SDO sapcecraft, acquired today September 25, 2010, superimposed and edited to show both surface (chromosphere) detail as well as coronal features, and an image of…

Pillar of Fire

Ok it’s not fire, it’s plasma, but it’s nevertheless a wonderful image by space photographer Alan Friedman showing a coronal ejection towering over 200,000 miles above the surface of the sun. It was taken on July 27, 2010. Coronal mass ejections (CMEs) occur when particularly large magnetic loops filled with plasma “snap” and expel their…
