เหตุการณ์ใน-นอกโลก VS ภัยธรรมชาติ และupdate พายุสุริยะ

ออโรร่าสีเลือด เกิดขึ้นหลายส่วนในอเมริกา ยุโรป

SPOOKY AURORAS: Some observers are calling it the "almost-Halloween storm." Blood red auroras that filled the skies over parts of the United States and Europe on Oct. 24-25 were certainly spooky. Indeed, veteran photographer Mike Hollingshead of Blair, Nebraska, felt the best place to capture the display was from a graveyard:

​

​

"At first the auroras seemed ordinary--that is, until the 'red surge madness' began," says Hollingshead. "Crazy bright shrouds of red light danced behind the head stones for 15 minutes." Other observers saw ghostly forms, moody trees, green phantasms, and more disturbing shades of red. Could Halloween itself be any more frightening?

​

Trick or treaters in Alaska, Canada and Scandinavia are about to find out. NOAA forecasters estimate a 15% to 25% chance of polar geomagnetic storms on Oct. 31st in response to a solar wind stream gently buffeting Earth's magnetic field. High-latitude sky watchers should be alert for spooky lights. Aurora alerts: text, voice. ​

 

DISINTEGRATING COMET: A small comet dove into the sun during the late hours of Oct. 30th. Blasted by intense solar heat, the 'dirty snowball' disintegrated in plain view of the Solar and Heliospheric Observatory (SOHO). Watch the movie and note how the comet shrinks to a pinprick just before it vanishes.

A Star with Spiral Arms


Oct 31, 2011: For more than four hundred years, astronomers have used telescopes to study the great variety of stars in our galaxy. Millions of distant suns have been catalogued. There are dwarf stars, giant stars, dead stars, exploding stars, binary stars; by now, you might suppose that every kind of star in the Milky Way had been seen.



That's why a recent discovery is so surprising. Researchers using the Subaru telescope in Hawaii have found a star with spiral arms.

Two spiral arms emerge from the gas-rich disk around SAO 206462, a young star in the constellation Lupus. This image, acquired by the Subaru Telescope and its HiCIAO instrument, is the first to show spiral arms in a circumstellar disk. The disk itself is some 14 billion miles across, or about twice the size of Pluto's orbit in our own solar system. (Credit: NAOJ/Subaru) [larger image]



The name of the star is SAO 206462. It's a young star more than four hundred light years from Earth in the constellation Lupus, the wolf. SAO 206462 attracted attention because it has a circumstellar disk--that is, a broad disk of dust and gas surrounding the star. Researchers strongly suspected that new planets might be coalescing inside the disk, which is about twice as wide as the orbit of Pluto.


When they took a closer look at SAO 206462 they found not planets, but arms. Astronomers have seen spiral arms before: they’re commonly found in pinwheel galaxies where hundreds of millions of stars spiral together around a common core. Finding a clear case of spiral arms around an individual star, however, is unprecedented¹.



The arms might be a sign that planets are forming within the disk.


"Detailed computer simulations have shown us that the gravitational pull of a planet inside a circumstellar disk can perturb gas and dust, creating spiral arms,” says Carol Grady, an astronomer with Eureka Scientific, Inc., who is based at NASA's Goddard Space Flight Center. “Now, for the first time, we're seeing these dynamical features."



Grady revealed the image to colleagues on Oct. 19^th at a meeting at Goddard entitled Signposts of Planets.



Theoretical models show that a single embedded planet may produce a spiral arm on each side of a disk. The structures around SAO 206462, however, do not form a matched pair, suggesting the presence of two unseen worlds, one for each arm.



Grady's research is part of a five-year international study of newborn stars and planets using the giant 8.2 meter Subaru Telescope. Operated by the National Astronomical Observatory of Japan, Subaru scans the heavens from a perch almost 14,000 feet above sea level at the summit of the Hawaiian volcano Mauna Kea. From there it has a crystal-clear view of innumerable young stars and their planet-forming disks throughout the Milky Way.



"What we're finding is that once these systems reach ages of a few million years—that’s young for a star--their disks begin to show all kinds of interesting shapes,” says John Wisniewski, a collaborator at the University of Washington in Seattle. "We’ve seen rings, divots, gaps--and now spiral features. Many of these structures could be caused by planets moving within the disks."



However, it is not an open and shut case. The research team cautions that processes unrelated to planets might give rise to these structures. Until more evidence is collected--or until the planets themselves are detected--they can’t be certain.
Whatever the cause of the arms, their reality is undeniable and the great catalogue of stars has one more type. Stay tuned to science@nasa for future entries.

SOLAR ACTIVITY IN THE OFFING: A big sunspot is emerging over the sun's NE limb. Yesterday it unleashed an M1-class solar flare (SDO movie) and hurled a coronal mass ejection into space. Geoeffective solar activity could increase in the days ahead as the sun's rotation turns the sunspot toward Earth.

BIG SUNSPOT: A large sunspot group is rotating over the sun's northeastern limb, possibly signaling an uptick in solar activity. NASA's Solar Dynamics Observatory took this picture during the early hours of Nov. 2nd:

​

Measuring some 40,000 km wide and at least twice that in length, the behemoth active region is an easy target for backyard solar telescopes. Astronomers are encouraged to monitor the region: NOAA forecasters estimate a 60% chance of M-class solar flares during the next 24 hours. Eruptions today would not be Earth directed, but future eruptions could be as the sunspot turns toward our planet in the days ahead. Solar flare alerts: text, voice.

NORTHERN LIGHTS: November began with a geomagnetic storm. A shock wave in the solar wind swept past Earth during the early hours of Nov 1st, sparking strong magnetic disturbances around the Arctic Circle. Paul Beebe sends this report from Upsala, Canada: "I awoke around 6:30 am and saw auroras out my bedroom window. They were dancing like green flames in the northern sky, with the occasional spike of pink or red barely visible." He quickly dressed and headed to the shores of nearby Lang Lake for this shot:​

​

More auroras are possible on Nov. 4th. A coronal mass ejection (CME) left the sun on Oct. 31st when a solar filament erupted; the cloud could deliver a glancing blow to Earth's magnetic field this Thursday. Aurora alerts: text, voice. ​
