Universe Today

It’s time once again for another Where In The Universe Challenge. Test your visual knowledge of the cosmos by naming where in the Universe this image was taken and give yourself extra points if you can name the spacecraft responsible for this picture. Post your guesses in the comments section, and check back later at this same post to find the answer. To make this challenge fun for everyone, please don’t include links or extensive explanations with your answer. Good luck!

UPDATE: The answer has been posted below.

NASA Administrator Charlie Bolden has asked for an evaluation of alternative heavy lift rockets, including DIRECT’s Jupiter launch vehicle. The evaluation is a “top priority,” according to NASASpaceflight.com, and a special team from the Marshall Space Flight Center has been commissioned to conduct the study, with the directive to have a report ready by the end of November. Looking at alternatives to the Constellation program is an apparent reaction to the final Augustine Commission report, which will be made public on Thursday.

If you had the opportunity this morning to witness the offspring of Comet Halley, then I'm curious as to what you might have noticed about this reliable annual meteor shower. Click to continue…

Some of the most frequently asked questions we get here at Universe Today and Astronomy Cast deal with black holes. Everyone wants to know what conditions would be like at the event horizon, or even inside a black hole. Answering those questions is difficult because so much about black holes is unknown. Black holes can't be observed directly because their immense gravity won't let light escape. But in just the past week, three different research teams have released their findings in their attempts to create black holes – or at least conditions analogous to them to advance our understanding.

It's not often that both hemispheres of the Earth get treated to an annual meteor shower, but in a matter of hours the complex Orionid stream is heading to dark sky your way! Where and when do you watch? Will it be as good as this year's Perseids as filmed by John Chumack above? Try even better! Follow me… Click to continue…

If you've had an opportunity over the last few days to check in on our IYA "Live" Telescope, we've been keeping an eye on the Messier Catalog Objects for you… specifically some bright open clusters named M46, M47 and M48! If you didn't get a chance to catch them while they were on the air, then feel free to have a look at our video capture… Click to continue…

This week's Carnival of Space is hosted by Robert Simpson over at Orbiting Frog.

Click here to read the Carnival of Space #125.

And if you’re interested in looking back, here’s an archive to all the past Carnivals of Space. If you’ve got a space-related blog, you should really join the carnival. Just email an entry to carnivalofspace@gmail.com, and the next host will link to it. It will help get awareness out there about your writing, help you meet others in the space community – and community is what blogging is all about. And if you really want to help out, let Fraser know if you can be a host, and he’ll schedule you into the calendar.

Finally, if you run a space-related blog, please post a link to the Carnival of Space. Help us get the word out.

The basic chemistry for life has been detected the atmosphere of a second hot gas planet, HD 209458b. Data from the Hubble and Spitzer Space Telescopes provided spectral observations that revealed molecules of carbon dioxide, methane and water vapor in the planet's atmosphere. The Jupiter-sized planet – which occupies a tight, 3.5-day orbit around a sun-like star — is not habitable but it has the same chemistry that, if found around a rocky planet in the future, could indicate the presence of life. Astronomers are excited about the detection, as it shows the potential of being able to characterize planets where life could exist.

"The Stick" made it out to launchpad 39B without falling over. I have to admit, NASA's new rocket looked tall, super-skinny and pointy (as Dr. Brian Cox described it), as it rolled out on the crawler transporter. Somehow, it seems the Ares I-X should be wider. It's definitely tall — at 100 meters (327 feet,) it is 43 meters (143 feet) taller than the space shuttle. But appearances aside, this is an historic occasion. For the first time in more than a quarter century, a new vehicle is sitting out at the launchpad at Kennedy Space Center in Florida.

Times are tough, but you have to wonder what this guy was thinking. Stewart David Nozette, 52, who was involved in the recent discovery of water on the Moon by the Chandrayaan-1 spacecraft has been arrested for espionage for allegedly trying to sell details of US missile detection satellites in exchange for cash. Nozette was attempting to sell classified information to a person who he believed was an Israeli intelligence officer. Nozette is a fairly prominent scientist who helped conceive the 1994 Clementine mission to the Moon, and currently is a co-investigator on Chandrayaan-1, the Indian Moon mission, and on an instrument aboard the Lunar Reconnaissance Orbiter.

To prepare for an actual attempt to extract the Spirit rover from its sand-trapped predicament, engineers using test rovers on Earth have added a new challenge. Until last week, those commanding and assessing drives by the test rovers were usually in the same room as the sandbox setup simulating Spirit's predicament, where they can watch how each test goes. That changed for the latest preparation, called an operational readiness test.

It was a busy weekend in the world of space flight — both present and future — and so we'll try to fit it all in one article, and include a couple of videos to help tell the stories. Before that, however, just a reminder that the Ares-I-X is slated to roll out to launchpad 39-B early Tuesday morning at 12:01 am EDT, to begin preparations for the scheduled Oct. 27 first test launch. If you're an early bird, (or a night owl) watch the six-hour trip on NASA TV.

And now on to this weekend's launch story:

I know this has nothing to do with space exploration, but my Dad posted a video of his trip up and down the spiral staircase he built around the outside of a tree on his property (I grew on up Hornby Island, BC). The staircase has 99 stairs and goes up for about 75 feet (25 meters). He's built a platform at the top where you can sit and see mountains and the ocean. And I spend my summer visits pulling the kids off the thing. Here's a link to Dad's blog (he's a photographer, by trade, so I have a well documented childhood).

P.S. Oh, and Dad made it clear that the bird's nest was old and empty.

It's the old shuttle shuffle. The launch of Atlantis for the STS-129 mission has been pushed back by four days to November 16 (at 2:28 pm EDT) to accommodate two unmanned rocket launches from Cape Canaveral, as well as the inaugural launch of the Ares I-X, scheduled for October 27. Right now the shuttle launch window lasts one day – the 16th. A second launch attempt on November 17 is being negotiated with a Delta IV launch, but NASA will stand down the 18th for the Leonid Meteor Shower (NASA won't launch the shuttle into a shooting gallery), so if weather or technical issues don't allow liftoff then, the next window opens from December 6-14. But there are issues with that time frame, too.

A huge, mysterious basin off the coast of India could be the largest, multi-ringed impact crater ever found on Earth. And if a new study is right, this impact may supercede the one that created the Chicxulub crater off Mexico's Yucatán Peninsula as what may have been responsible for killing the dinosaurs 65 million years ago. Sankar Chatterjee of Texas Tech University and a team of researchers have been studying a 500-kilometer-wide (300-mile-wide) depression on the Indian Ocean seafloor which was likely created by a bolide perhaps 40 kilometers (25 miles) in diameter. Such an event would have triggered worldwide climate changes, including intensified volcanism, that led to mass extinction.
