You heard about the big X4.9 solar flare at 00:50 GMT Monday I suspect. Phil Plait at Bad Astronomy is always the go to person on that, but NASA has a video out of the fare in different wavelengths that is pretty cool. The sunspot that produced the flare is rotating slowly around, and will be facing Earth in a few days. If it erupts again then we may be …

How can you tell the difference between white clouds and white snow on a satellite image?? Rivers don’t run through clouds! Study the image from the Aqua satellite today above and you will see what i mean. Speaking of satellite images of icy cold, the folks at CIMMS at the Uni. of Wisconsin posted the animated gif below showing ice forming on Lake Michigan. Speaking of ice, I had a …

Just when everyone thought that little of it survived its high speed solar dive…. Stay tuned! More from NASA here.

No Christmas comet it seems. NASA satellites (including SOHO) show Ison breaking apart and dimming as it approached the Sun today. Update 04:10 GMT Friday: There seems to be some indication that at least part of the comet survived. The most definitive word on it as of now is here: http://www.isoncampaign.org/karl/schroedingers-comet

A large high pressure system is producing clear skies over much of the eastern Seaboard tonight, and the visibility is excellent. This launch will actually put 29 different satellites in orbit, including one designed by a group of high school students! I’m just 40 miles away from it here in Salisbury, and should have a great view of the launch. I’ll post some pics of it later tonight here.( A …

I know others have blogged this today, but for those that missed it… and an annotated version- WOW!

NASA is taking their Operation Ice Bridge back to Antarctica later this month after the mission was almost cancelled by the government shutdown.. This will be the first time the NASA P3 Orion aircraft will make the trip, and land on the ice runway at McMurdo Science Base. Ice Bridge has filled in the gaps in ice sheet measurements since Icesat 1 died. Icesat 2 will launch in 2016. Here’s …

A lot of science blogs have mentioned the science errors in the film Gravity recently, but this is a movie review on Ron Howard’s Apollo 13. Yes, I know the film came out 18 years ago, but better late than never! You see Gravity is a made up story, and while the errors are pretty egregious, I do not think it matters as much, because after all, it is a …

Nice shot of the peak fall color in the Adirondack’s from the true color MODIS on the Terra satellite. Some pretty cirrus as well, but can you spot the jet contrails??

Now that the Federal Government has shut down, here are some of the effects in the science community. 1. Curiosity on Mars is being put into hibernation mode. (Update: Am told Curiosity is still doing science… for now…) (Update Wed. 2 AM: Because JPL acts as a contractor Curiosity is still being operated as of now. See HERE.) 2. Almost all (97%) of NASA will shut down with the exception …

Last week’s news that Voyager 1 had become the first human made object to enter interstellar space gave almost everyone a pause, including me. I was a young and dumb freshman student at the University of Oklahoma that fall, trying to get my head around calculus as matter of fact. It’s been thirty-six years, and my hair is gray, but Voyager travels on. I suspect a lot of teachers around …

Apparently this image is not a fake. A Virginia frog that was in the wrong place in space and time… Happened last Friday during the launch of the LADEE mission at Wallops Island in Virginia.

Atmospheric physicist Nick Gorkavyi missed witnessing an event of the century last winter when a meteor exploded over his hometown of Chelyabinsk, Russia. From Greenbelt, Md., however, NASA’s Gorkavyi and colleagues witnessed a never-before-seen view of the atmospheric aftermath of the explosion.

A larger version is here. From NASA JPL today: PASADENA, Calif. — Color and black-and-white images of Earth taken by two NASA interplanetary spacecraft on July 19 show our planet and its moon as bright beacons from millions of miles away in space. NASA’s Cassini spacecraft captured the color images of Earth and the moon from its perch in the Saturn system nearly 900 million miles (1.5 billion kilometers) away. …

NASA have collected an excellent satellite image of the Bingham Canyon landslide in Utah, USA

The GOES R satellite will be able to do ONE minute rapid scans in two different locations when it is launched in two years! (If budget cuts don’t delay it, we will finally catch up to Europe with satellite technology.) Here is a wider shot (Visible channel) of 15 min images. Hat tip to Metr. Brad Panovich for this one: and an IR/VIS POES Image below:

GOES 13 is one of two Geostationary Operational Environmental Satellites used for forecasting in the Western hemisphere. Late word tonight is that an attempt to revive it has failed and the backup satellite GOES 14 is being activated We should start seeing some images by midnight Eastern USA time. It will take another day to get normal coverage back. The GOES West satellite does give some coverage of the Eastern USA but it is poor at best …

Every summer, thousands of people drive out to Chincoteague in Virginia to see the beautiful beach, wild ponies, and the stunning National Wildlife Refuge. To get there, they drive around the long NASA runway at the Wallops Island Flight facility, and you can’t help noticing the cluster of big satellite dishes. If you’ve been there, you probably have wondered just what all those dishes are for. Meteorologists already know, and you’re about to find …

The view from the NASA Terra satellite this afternoon is just stunning. It shows the cold and snow of winter remaining over Canada but look at the advancing bright green spring in Virginia! This is a true colour image from low Earth orbit. Click here for a BIG version!
