Carnival of Space: 203

It’s Carnival time in the Gutter again! We’re hosting this week’s round-up of space and astronomy blogging news. If you’d like to find out more or get involved yourself check out the Carnival’s homepage over at Universe Today.

We’re kicking off this week with the massive Solar flare that exploded from the Sun on 7th June. The Chandra blog explains what they had to do to protect the satellite from the incoming radiation. If you didn’t see any of the movies of the flare, or if you’re unsure just how big this eruption was I strongly recommend the following, courtesy of Matt Parker:

Next up is the Pan-STARRS1 project which has discovered a new comet in the outer Solar System which could reach naked eye visibility in March 2013. One of the astronomers who discovered the comet Richard Wainscoat outlines how it was found and what we know about its orbit.

Virtual telescopes such as Google Sky, World Wide Telescope and Wiki Sky have allowed people to explore the sky in great detail at many different wavelengths, and look for their own mysterious sky objects. However, if you don’t have some understanding of what you’re looking at you can end up with misidentifications, such as the ones discsussed by the Astroblog for comet Elenin and the mythical planet Nibiru.

If you want to know more about why astronomers use many different wavelengths for their observations check out the first of Cheap Astronomy’s two part podcast series on astronomy across the electromagnetic spectrum.

Over to Mars now. Vintage Space looks at the challenges in designing and testing the parachutes that slow the descent of the landers that are sent there. Once they reach the surface the pictures they send back can seem very familiar – head over to The Meridiani Journal to see an excellent example of “mud polygons” or mud cracks on Earth, and their striking similarity to the bedrock terrain seen by Opportunity in Meridiani on Mars.

Could Saturn’s moon Enceladus have a salt-water ocean? NASA’s Cassini spacecraft has already confirmed that there’s liquid water below the surface, but now it may also have detected salt grains in the plumes of icy spray shooting up from its surface. Both Discovery News and Weirdwarp have the full story.

Next Big Future brings news of a new supersonic business jet concept, the SonicStar, which was unveiled at the Paris airshow. It promises flight times from Paris to New York of under 2 hours thanks to its revolutionary engine design. If you want to travel a little further though, they also have an interview with writer Keith Henson about his ideas for cheaper space launches using a combination of Skylon rocket planes and concentrated lasers.

There’s two slightly more offbeat offerings to end on. First, shhh, don’t tell anyone but Universe Today has been spying on spy satellites, thanks to the skill of astrophotographer extraordinaire Thierry Legault. Check out the post if you want to know how he does it.

Finally, could the forthcoming movie Iron Sky have any basis in fact? Everyone knows that WW2 Germany developed rockets far in advance of the Allies, but some argue that in 1945 the Third Reich was on the verge of developing a space program. Armagh Planetarium’s Astronotes finds out more.

Well, that’s it for this week. Hope you’ve enjoyed this somewhat surprising journey from solar flares to spies and Nazis!

  1. [...] Carnival of space 203 is up at weareallintheGutter.com Discovery News – In 2010, scientists confirmed the enigmatic Saturnian moon Enceladus possesses a sub-surface ocean of liquid water. This groundbreaking discovery was made by NASA’s Cassini spacecraft currently in orbit around Saturn. Today, mission scientists have further analyzed Cassini data from various Enceladus flybys to find that it’s not only a liquid water ocean; it could be salty too. [...]
