We Are Made of Stardust

This brief quote by the late Carl Sagan is wonderfully illustrated in the beautiful and poignant short film “Stardust,” directed by Mischa Rozema of Amsterdam-based media company PostPanic. Using actual images from space exploration as well as CGI modeling, Stardust reminds us that everything we and the world around us are made of was created inside stars… and that, one day, our home star will once again free all that “stuff” back out into the Universe.

The film was made in memory of talented Dutch designer Arjan Groot, who died of cancer in July 2011 at the age of 39.

“I wanted to show the universe as a beautiful but also destructive place. It’s somewhere we all have to find our place within. As a director, making Stardust was a very personal experience but it’s not intended to be a personal film and I would want people to attach their own meanings to the film so that they can also find comfort based on their own histories and lives.”
– Mischa Rozema, director

A truly stunning tribute.

AR1654 is a Monster Sunspot. (And It’s Aiming Our Way.)

Active Region 1654 on the Sun’s western limb, seen by SDO on Jan. 11 (NASA/SDO/HMI team. Diagram by J. Major.)

Like an enormous cannon that is slowly turning its barrel toward us, the latest giant sunspot region AR1654 is steadily moving into position to face Earth, loaded with plenty of magnetic energy to create M-class flares — moderate-sized outbursts of solar energy that have the potential to cause brief radio blackouts on Earth and, at the very least, spark bright aurorae around the upper latitudes.

According to SpaceWeather.com, AR1654 “could be the sunspot that breaks the recent lengthy spell of calm space weather around our planet.”

The image above, captured by NASA’s Solar Dynamics Observatory earlier today, shows the structure of AR1654 upon the Sun’s photosphere — its light-emitting “surface” layer. Stretching many tens of thousands of miles, this magnetic solar blemish easily dwarfs our entire planet. And it’s not just a prediction that this sunspot will unleash a flare — it already has.

AR1654 came around the limb of the sun crackling with activity. Shortly after the probability of AR1654 releasing a flare was raised to 50% it did just that, letting loose with a burst of magnetic energy that was observed by SDO’s multi-channel cameras. Watch the video below:

Peaking at 9:11 UTC, this M1-class flare won’t have much more effect on Earth than perhaps some radio and GPS interference and maybe increased auroral activity. But AR1654 is still evolving and growing… and moving to face us.

In the meantime, solar astronomers and observatories like SDO are keeping an ever-watchful eye on this magnetic monster.

Keep up with the latest news here on Universe Today, on the SDO mission site and on spaceweather.com.

UPDATE 1/12: According to the NOAA, AR1654 has a 5% chance of producing an X-class flare, based on its current magnetic activity and alignment.

A sunspot is a magnetically active region on the sun that appears dark because it’s relatively cooler than the surrounding area—6,000ºF (3,300ºC) versus 10,000ºF (5,500º C). Sunspots are where solar flares are most likely to occur since the magnetic fields in these active regions can build up enough energy to break, releasing bursts of intense radiation into the solar system.

The Sun has been active recently along with showing several sunspots. But astrophotogher Efrain Morales captured an additional ‘man-made’ sunspot as the International Space Station transited across the face of the solar disk.

“It was a challenge as the Sun was low on the horizon at 19.5 deg. elevation, just above the canopy of the forest,” Efrain said via email, “along with and the ISS being over 250 miles distant from my location passing over Haiti at the time. His home base is the Jaicoa Observatory in Puerto Rico.

Equipment: SolarMax40, P/B CGE mount, Flea3 Ccd.

Below, see an animation of the ISS transit:

A few sunspots are now ‘peppering” the surface of our Sun — Spaceweather.com lists about 12 different sunspot groups today. Yesterday (January 7, 2013), astrophotographer John Chumack stepped outside over his lunch break and captured some cool-looking views of the Sun from his observatory in Ohio, using different filters.

See more below, plus the Solar Dynamics Observatory has a spectacular video of coronal loops on the Sun during January 5 through 7.

The video shows the 171 angstroms channel, which is especially good at showing coronal loops – the arcs extending off of the Sun where plasma moves along the magnetic field lines, said the SDO team. The brightest spots seen here are locations where the magnetic field near the surface is exceptionally strong. The characteristic temperature here is 1 million K (or 1.8 million F).

Many of these loops could fit several Earths inside of them.

Different views from different filters from John Chumack:

Catching Sunlight: A TEDx Talk by DIY Solar Photographer Alan Friedman

Video poster frame shows Alan Friedman’s 90mm hydrogen alpha telescope setup — nicknamed “Little Big Man” — on an Astro-Physics 900 equatorial mount.

We’ve featured several beautiful images of the Sun here on Universe Today, captured by the talented Alan Friedman from his backyard telescope in Buffalo, NY. While photos of the Sun in and of themselves are nothing new in astronomy, Alan’s images always seem to bring out the best in our home star. Maybe it’s the magical nature of hydrogen alpha photography, maybe it’s Alan’s fancy new Grasshopper CCD camera, maybe the Sun’s photosphere was looking particularly nice on those days… but most likely Alan just has an innate skill for solar photography (as well as one for picking out great hats!)

In the video above, Alan talks to an audience at a TEDx event in Buffalo on October 9, sharing some of his photos and explaining why he does what he does, and why he feels do-it-yourself astrophotography is such a valuable thing to share with others. It’s a great bit of insight from a talented artist (and you just might recognize the names he drops at 13:55!)

I was happy to share one of Alan’s images on my own website back in 2010, which Phil Plait (the “Bad Astronomer,” who was then with Discover Magazine) picked up on and soon enough the whole thing got Alan quite a bit of attention. Which, when you’re an astrophotographer and graphic artist (he also sells art prints of his work as well as runs a greeting card studio) is never a bad thing.

Today’s Solstice Sun

This beautiful image from the Solar Dynamics Observatory provides a view of our Sun on the solstice (winter solstice for the northern hemisphere and summer solstice for the southern hemisphere,) at 11:12 UTC, December 21, 2012. No killer solar flares, no apocalypse, just pure beauty and the life-giving light and warmth from Old Sol.

Happy solstice to all!

International Space Station Making New Solar Observations

The International Space Station. Credit: NASA

This weekend the International Space Station will turn itself to face the Sun, enabling ESA’s SOLAR instrument to capture an entire rotation of the solar surface. This is the first time the Station has changed attitude for scientific reasons alone.

This instrument has been on the ISS since 2008, and for the first time will record a full rotation of the Sun. It began this effort on November 19, 2012, and on December 1, the Station will spend two hours turning about 7 degrees so that observations can continue. It will hold this angle for ten days before returning to its original attitude.

“We want to record a complete rotation of the Sun and that takes around 25 days,” said Nadia This, operations engineer at the Belgian User Support and Operations Centre that controls SOLAR.

SOLAR needs to be in direct view of the Sun to take measurements but the Space Station’s normal orbit obscures the view for two weeks every month.

All the international partners had to agree on changing the ISS’s orientation.

However, moving a 450-ton orbital outpost the size of a city block isn’t a simple undertaking. Aside from calculating the correct orbit to keep SOLAR in view of the Sun, other factors need to be taken into account such as ensuring the solar panels that power the Station also face the Sun. Additionally, communication antennas need to be reoriented to stay in contact with Earth and other scientific experiments must be adjusted.

The SOLAR instrument was originally designed to last about 18 months, but has been going strong for 5 years. It is installed on the outside of the ESA’s Columbus module.

The SOLAR payload consists of three instruments to the solar spectral irradiance throughout virtually the whole electromagnetic spectrum.

The three complementary solar science instruments are:

SOVIM (SOlar Variable and Irradiance Monitor), which covers near-UV, visible and thermal regions of the spectrum.
SOLSPEC (SOLar SPECctral Irradiance measurements) covers the 180 nm – 3 000 nm range.
SOL-ACES (SOLar Auto-Calibrating Extreme UV/UV Spectrophotometers) measures the EUV/UV spectral regime.

Scientists say SOLAR’s observations are improving our understanding of the Sun and allowing scientists to create accurate computer models and predict its behavior.

A Branching “Tree” of Solar Plasma

Hydrogen-alpha photo of the Sun by Alan Friedman

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 — along with an idea of just how big this “tree” is — after the jump:

Taken through a special solar telescope and a Grasshopper CCD camera, Alan’s gorgeous solar photos show the Sun in a wavelength absorbed by atomic hydrogen — most present in the photosphere and chromosphere — thus revealing the complex and dynamic activity of the Sun’s “surface”.

Here’s the full image:

The dark circle at upper left (added by me) shows approximately the scale size of Earth (12,756 km, or about 7,926 miles diameter.) As you can see, that particular prominence is easily six times that in altitude, and spreads out many more times wider… and this isn’t even a particularly large prominence! As far as solar activity goes, this is a non-event. (Not like what was seen by SDO on Nov. 16!)

Regardless, it makes for an impressive backyard photo.

Check out more of Alan’s photos on his blog and on his website, AvertedImagination.com. Many of his photos, some of which have been shown at galleries across the U.S., are available as limited-edition prints. (Alan also runs a greeting card print studio.) I’ve found that he usually shares at least a couple of fantastic solar shots every month, if not more.

Disco Sun: X-Class Flare Creates Strobe-Light Effect

An active region just turning into view on the left side of the Sun has emitted three large flares since Saturday: an M9, an M5 and early today blasted out an X1.8 class flare. This flare occurred around 3:17 am UTC today (or 11:17 pm EDT on Oct. 22). The strobe-light-like effect visible in the video was created by the brightness of the flare and how the instruments on the Solar Dynamics Observatory responded to it. Phil Chamberlin, Deputy Project Scientist SDO told Universe Today that built in algorithms called ‘active exposure control’ compensate for the extra light coming in from a flare. It doesn’t always result in the strobe or fluttering effect, but the algorithms create shorter exposure time, and thus a dimmer, but still scientifically useful view of the entire Sun. The algorithms go into effect whenever there is an M class or higher flare.

Solar flares are powerful bursts of radiation. Harmful radiation from a flare can’t pass through Earth’s atmosphere and pose a hazard to humans on the ground, but flares like this can disturb the atmosphere in the layer where GPS and communications signals travel, and an X-class flare of this intensity can cause problems or even blackouts in radio communications.

A Coronal Mass Ejection (CME) was not associated with this flare, and the flare was not directed at Earth, so scientists do not expect any additional auroral activity to be a result of this latest blast from the Sun.

The SDO Twitter feed said there is a 75% chance of more M-class solar flares from this active region and a 20% chance of additional X-class flares.

This is the 7th X-class flare in 2012 with the largest being an X5.4 flare on March 7.

By observing the sun in a number of different wavelengths, NASA’s telescopes can tease out different aspects of events on the sun. These four images of a solar flare on Oct. 22, 2012, show from the top left, and moving clockwise: light from the sun in the 171 Angstrom wavelength, which shows the structure of loops of solar material in the sun’s atmosphere, the corona; light in 335 Angstroms, which highlights light from active regions in the corona; a magnetogram, which shows magnetically active regions on the sun; light in the 304 Angstrom wavelength, which shows light from the region of the sun’s atmosphere where flares originate.
