Universe Today

Here's some refreshing news! In an era when mainstream media is cutting back on their science departments and science reporting, the Discovery Channel has just made an investment to step-up their science news with the re-launch of their new and improved news website, Discovery News. In the middle of it all is our very own Ian O'Neill, who is also the producer for Discovery News Space. The "new" part of Discovery News is that Ian's work on the space side is now integrated into a higher profile, redesigned news site. Ian and I had a chance to talk today about this good news for science news.

The English language continually evolves. Just see Ambrose Bierce's definition of dictionary. New concepts call for new words that often evolve from a new dictum. Astronomy has made its fair share of contributions to this cause. But, Daniel Hudon's book "The Bluffer's Guide to: The Cosmos" belies such augmentations. Within, the language is as common and everyday as what you used around the gas pump or barber shop. Yet, the science and information is as exact and appropriate as needed to communicate an idea.

While astronomers have studied both big and little black holes for decades, evidence for those middle-sized black holes has been much harder to come by. Now, astronomers at NASA's Goddard Space Flight Center in Greenbelt, Md., find that an X-ray source in galaxy NGC 5408 represents one of the best cases for a middleweight black hole to date. "Intermediate-mass black holes contain between 100 and 10,000 times the sun's mass," explained Tod Strohmayer, an astrophysicist at Goddard. "We observe the heavyweight black holes in the centers of galaxies and the lightweight ones orbiting stars in our own galaxy. But finding the 'tweeners' remains a challenge."

All we can say is, "Wow!" In celebration of the International Year of Astronomy 2009, NASA's Great Observatories — the Hubble Space Telescope, the Spitzer Space Telescope, and the Chandra X-ray Observatory — have collaborated to produce an unprecedented image of the central region of our Milky Way galaxy. This is a never-before-seen view of the turbulent heart of our home galaxy. The image is being unveiled by NASA to commemorate the anniversary of when Galileo first turned his telescope to the heavens in 1609. NASA provided this image and the individual images taken by each of the Great Observatories to more than 150 planetariums, museums, nature centers, libraries, and schools across the country.

A problem-plagued Japanese mission to an asteroid just may have received its final blow. The Haybusa mission, which went to asteroid Itokawa in 2005 is currently trying to return to Earth, but now has suffered a breakdown in the third out of four ion thrusters. The cause was a voltage spike due to problems with a neutralization vessel, which previously caused the failure of two other thrusters. The fourth and only remaining thruster was shutdown earlier by engineers after signs that it also might succumb to high voltage damage. Engineers are now testing that engine, Thruster C, to determine if it is capable of long-duration firings. Hayabusa, which landed on Itokawa (possibly several times – mission managers aren't sure) might contain samples, but due to a malfunction of the sample collection device, JAXA has acknowledged that it cannot be sure Hayabusa actually managed to take samples from the surface of the asteroid.

This week's Carnival of Space is hosted over at AARTScope Blog.

Click here to read the Carnival of Space #128.

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.

A new module for the space station blasted off today from the Baikonur Cosmodrome, Kazakhstan at 9:22 a.m. EST. The Poisk (which means "explore" in Russian) is a combination docking module/airlock/future research module. It will meet up with the ISS on Thursday at 10:44 am. Poisk is the first permanent pressurized module to be added since May of 2008, when the Japanese "JEM" research module became part of the ISS, and is the first major Russian addition to the station since the Pirs docking compartment was launched in 2001. The new module will be used as an additional docking port for Russian vehicles, as an airlock for Russian-based spacewalks and as a platform for external science experiments.

NASA has been keeping an eye on tropical storm Ida off the Gulf Coast, which was downgraded from a hurricane earlier today. Its satellites have been helping meteorologists to measure the rainfall and windspeeds of the storm. Ida is predicted by the National Hurricane Center in Miami, Florida to make landfall near Pensacola, Florida on Tuesday morning (Nov. 10th), after which it is expected to drop in intensity and head East.

Here are the first images of the Apollo 11 landing site since the Lunar Reconnaissance Orbiter dropped into its 50 km mapping orbit. The sun is almost straight overhead on this image so there's no real shadows visible. What's great about this image is that we can actually see the footpads on the Lunar Module from which Armstrong made his giant leap for mankind! See the closeup below for more details. The other great thing about this top image is that we get a good look at West Crater, which is the rocky area that Neil Armstrong saw as the LM neared the surface. The computer trajectory would have taken them right in the middle of that boulder field, so Armstrong flew manually to change the flight plan to fly westward to find a safe landing spot. This image is 742 meters wide (about 0.46 miles). North is towards the top of the image.

The Spirit Rover, which has had its wheels stuck for 145 Martian sols, has finally moved! Though she's far from being extricated from her current position, this is the first time that she's budged in quite a while. The Mars rover driving team is working on ways to get Sprit out, and this recent move was just them getting Spirit's wheels in alignment for an upcoming procedure to free her from the sand trap she's stuck in. But it's a start!

A previously undiscovered asteroid came within 14,000 km (8,700 miles) of Earth last week, and astronomers noticed it only 15 hours before closest approach. On Nov. 6 at around 16:30 EST a 7 meter asteroid, now called 2009 VA, came only about 2 Earth radii from impacting our home planet. This is the third-closest known non-impacting Earth approach on record for a cataloged asteroid.

On the 75th anniversary of astronomer Carl Sagan's birth, the Planetary Society announced their plans to sail a spacecraft on sunlight alone by the end of 2010. Called LightSail, the project will launch three separate spacecraft over the course of several years, beginning with LightSail-1, which will demonstrate that sunlight alone can propel a spacecraft in Earth orbit. LightSails 2 and 3, will travel farther into space.

Sagan, co-founder of the Planetary Society was a long-time advocate of solar sailing.

Vitaly Ginzburg, a Russian physicist and Nobel laureate, died yesterday of cardiac arrest. He was 93 years old. Ginzburg shared the 2003 Nobel Prize in physics for his work on superconductors, but contributed to many other fields of study, including quantum theory, astrophysics, radio-astronomy and diffusion of cosmic radiation in the Earth's atmosphere. In addition, he is known for his contributions to the development of the Russian hydrogen bomb in the 1950s, for which he received the Stalin Prize. Click to continue…

A network of time-lapse cameras set up in the Nullarbor Plain desert of Western Australia has allowed researchers to track a fallen meteorite to the ground, and enabled them to determine its original orbit and parent body. The meteorite has a composition different than that of other meteors, leading researchers to believe that it originates from a different parent body than most meteorites that impact Earth. The Desert Fireball Network, a project coordinated by the Imperial College of London, was able to track the meteor when it entered the atmosphere, giving researchers an impact location and information on where it originated.
