Carnival of Space #180

Wel­come, wel­come to the Web’s 180th spec­tac­u­lar Car­ni­val of Space. You say you don’t know what this car­ni­val is all about? Hosted by our illus­tri­ous ring-leader, Fraser Cain, you can head over to the Car­ni­val home­page for the full details and archive.

My God it’s full of stars! Three times more stars by astronomers’ count accord­ing to Brian Wang at Next Big Future. A bet­ter count of red dwarf stars finds 20 times more in ellip­ti­cal galax­ies. That boosts the esti­mates for the num­ber of stars in the uni­verse to 300 sex­til­lion. Astronotes calls red dwarfs the most impor­tant stars in the universe.

Last week, the Web was awash in dis­cus­sions about NASA’s cryp­tic press release that inti­mated an “astro­bi­ol­ogy find­ing that will impact the search for evi­dence of extrater­res­trial life.” Many blog­gers spec­u­lated that per­haps life had been found on one of Saturn’s moons. That was not the case. Next Big Future takes us through the announce­ment that life can have arsenic instead of phos­phate as a basic build­ing block.

Next Big Future also offers spec­u­la­tion that a dark jupiter (or sev­eral) might lurk around the edge of the solar system.

Nancy Atkin­son, at Uni­verse Today, writes that researchers find that the tracks from the two Mars rovers are being erased by wind within a Mar­t­ian year.

Paul Schenk offers us the first view of global topo­graphic maps of Saturn’s icy moons.

Allen Vers­feld, the Urban Astronomer, takes a look at the his­tory of Neptune’s dis­cov­ery, the mythol­ogy behind its name and a lit­tle bit of the sci­ence behind the planet.

When I was in grade school, one couldn’t help but notice that the orbital work­shop Sky­lab looked sim­i­lar to a stage of a Sat­urn V. David S. F. Portree, of Beyond Apollo, tells us about the non-propulsive roles of the S-IVB rocket stage in NASA’s manned pro­gram.

Want a baked piece of his­tory? If you’re a school or uni­ver­sity, Robert Pearl­man of col­lect­Space, shares that NASA has started offer­ing schools space shut­tle tiles at a whop­ping $23.40 per tile (that’s just ship­ping and handling).

Mov­ing a bit closer to home but far­ther back in time, Bruce Leee­owe, at Weird Sci­ences writes about a research arti­cle by Vic­tor Bab­bitt in which Bab­bitt pro­posed that sul­fur diox­ide unleashed after a cometary impact may have caused the pos­si­ble extinc­tion of dinosaurs.

While Leee­owe talks of extinc­tions, astronomers are search­ing for life else­where in the uni­verse. One new method, explains Weird Warp, is to seek sul­fur diox­ide sig­na­tures, and there­fore vol­ca­noes, on exo­plan­ets. This leads us to AARTScope’s story about ESO’s spec­tropho­tom­e­try announce­ment of a steamy or hazy “super-Earth” called GJ 1214b.

Last week also saw a fair num­ber of sto­ries about cos­mol­ogy. Sci­ence is stranger than fic­tion accord­ing to Ian O’Neill at Dis­cov­ery News. Sci­en­tists ana­lyz­ing cos­mic microwave back­ground radi­a­tion claim they observe a pat­tern, says O’Neill. Fran­cisco José Sevilla Lobato, in his Spanish-language blog Vega 0.0, writes about the impact of infrared obser­va­tions in mod­erm cosmology.

The folks at the blog weare­allinthegut­ter remind us in why super­novae are so impor­tant for cos­mol­ogy in parts one and two at their website.

Steve Ner­lich, of Cheap Astron­omy, with help from some lis­ten­ers, deliv­ers a 2010 hol­i­day sea­son 365 days of Astron­omy pod­cast on 21st cen­tury think­ing.

We are lucky enough as Car­ni­val read­ers to have a cou­ple of blog­gers who offer a far view of our explo­ration of space. Weird Sci­ences dis­cusses the advan­tages of probes over con­ven­tional SETI bea­cons. Cen­tauri Dreams explores the tran­si­tion from inter­plan­e­tary flight to inter­stel­lar jour­neys. Pul­sar nav­i­ga­tion is one way to find our way around and an inter­est­ing new paper dis­cusses one way it might be done.

By the way, this week is brought to you by the word par­al­lax at AstroWoW. But the hol­i­day sea­son would not be com­plete with­out an iPod stock­ing stuffer idea from Bruce Irv­ing at Music of the Spheres or advent cal­en­dars from Zooni­verse, Big Pic­ture and Plan­e­tary Soci­ety’s Emily Lak­dawalla. You won’t want to miss a sin­gle day.

Welcome

The ancient peo­ples saw pic­tures in the sky. From those pat­terns in the heav­ens, ancient sto­ry­tellers cre­ated leg­ends about heroes, maid­ens, drag­ons, bears, cen­taurs, dogs and myth­i­cal crea­tures…
