Die Theorie, dass unser Mond durch eine Kollision mit der Erde und einem Mars-ähnlichen ursprünglich zehnten (Sorry Pluto, I still heart you) neunten Planeten entstanden ist, war mir jetzt nicht wirklich neu.

Dass aber dabei anfänglich zwei Monde entstanden sind, die dann kollidierten schon. Die Theorie stützt sich unter anderem auch auf die unterschiedlichen Oberflächen der uns zugewandten und der erdabgewandten Seite des Mondes.

A tiny second moon may once have orbited Earth before catastrophically slamming into the other one, a titanic clash that could explain why the two sides of the surviving lunar satellite are so different from each other, a new study suggests.

Their calculations suggest this second moon would have formed at the same time as our moon. Scientists have suggested that our moon was born from massive amounts of debris left over from a giant impact Earth suffered from a Mars-size body early on in the history of the solar system. Spare rubble might also have coalesced into another companion moon, one just 4 percent its mass and about 750 miles wide, or one-third of our moon’s diameter.

Earth may have had 2 moons

Der Independent hat einen interessanten Artikel über die Wissenschaft und die Marketinghintergründe von Trailern. Hier ein paar Auszüge.

“Teaser trailers can be launched up to a year ahead of release,” explains London-based publicist Rupert Fowler, who began his career in LA and has worked on many film campaigns. “Nearer to release there can be as many as five different versions, varying in length and concentrating on specific characters or themes, such as romance, suspense or action.”

The trailer came into being in 1913 when the Loews Cinemas company created one for the musical, The Pleasure Seekers, which was playing on Broadway. But the early days of trailers were usually maladroit and audiences immediately knew they were being sold something. The Bishop’s Wife in 1947 gave a knowing nod to such tactics with a self-referencing trailer staring David Niven and Cary Grant on their way to film a promo for the movie.

Until the 1950s, American trailers were produced by the National Screen Service, although some directors such as Alfred Hitchcock and John Ford liked to produce their own. In the 1960s film directors took a keener interest, leading to more stylish trailers. Plot spoilers in trailers still existed into the 1970s although trailers were less brash than today. “This is Universal’s extraordinary motion picture version of Peter Benchley’s best-selling novel, Jaws,” intoned the gentle voiceover on a trailer for Speilberg’s shark fest which, during its three minutes, showed so much footage and dialogue, it was akin to an abridged version of the film.
[…]
Over the years, trailers have been seen as worthy of study.

“They play on emotional impact, set up situations, and produce an overall feel, both aesthetic and emotional, very quickly,” says film expert Dr Kriss Ravetto-Biagioli, of Edinburgh University.

And some can be better than the films. “George Lucas’ Star Wars prequels were lousy but the trailers were incredibly stylish and expressive,” says Daniel Hesford, who is writing a thesis on the subject. “They used minimal percussive soundtracks, musical cues from the famous score, skilful montages and the best, most expressive and aesthetically spectacular shots from the films themselves.”

50 Jahre bemannte Raumfahrt

12 Apr, 2011 · Sascha · Wissenschaft · 0 comments

Heute, am 12. April, umkreiste vor nun genau 50 Jahren Yuri Gagarin in seiner Vostok (deutsch: Osten) als erster Mensch unseren Planeten. 50 Jahre. Das ist ein halbes fucking Jahrhundert. Und ich kann immer noch nicht mit Jetpacks auf Pluto rumhüpfen. Nein, Spaß beiseite. Die bemannte Raumfahrt steckt nach all den Jahren immer noch in den Kinderschuhen. Während die Amerikaner selbst ihr Spaceshuttleprogramm in wenigen Monaten eingestellt haben, sind es wieder einmal die Russen, auf die es dann ankommt. Vielleicht kann die nun deutlich erkennbare Privatisierung der Raumfahrt, vor allem in Amerika durch Firmen wie SpaceX, vorangetrieben werden, da man auf Grund steigender wirtschaftlicher Probleme den Leuten Raumfahrt immer schwieriger als wichtig vermitteln kann. Schade. Mir fehlen Politiker, die sich lautstark dafür einsetzen. Ich hielt Obama lange für solch einen bis er das NASA Budget drastig kürzte. Daher lohnt ein Blick in die Vergangenheit: Christopher Riley hat in Zusammenarbeit mit der ESA den wunderschönen Film FIRST ORBIT erstellt, der Gagarins Flug in Echtzeit nachstellt. Super interessant und faszinierend.

A real time recreation of Yuri Gagarin’s pioneering first orbit, shot entirely in space from on board the International Space Station. The film combines this new footage with Gagarin’s original mission audio and a new musical score by composer Philip Sheppard. For more information visit http://www.firstorbit.org

Schwarzes Loch frisst Stern

11 Apr, 2011 · Sascha · Wissenschaft · 0 comments

Wow. Ein NASA Satellit hat umwerfende Daten aufgefangen und bisher lässt sich für dieses ungewöhnliche Ereignis nur eine Konsequenz ziehen: Da muss ein schwarzes Loch einen ganzen Stern vom Sternenhimmel aufgesogen haben.

On March 28, 2011, NASA’s Swift satellite caught a flash of high-energy X-rays pouring in from deep space. Swift is designed to do this, and since its launch in 2004 has seen hundreds of such things, usually caused by stars exploding at the ends of their lives. But this time was hardly “usual”. It didn’t see a star exploding as a supernova, it saw a star literally getting torn apart as it fell too close to a black hole!

The event was labeled GRB 110328A –a gamma-ray burst seen in 2011, third month (March) on the 28th day (in other words, last week). Normal gamma-ray bursts are when supermassive stars collapse (or ultra-dense neutron stars merge) to form a black hole. This releases a titanic amount of energy, which can be seen clear across the Universe.

And those last two characteristics are certainly true of GRB 110328A; it’s nearly four billion light years away*, and the ferocity of its final moments is not to be underestimated: it peaked at a solid one trillion times the Sun’s brightness!

Astronomers may have witnessed a star torn apart by a black hole

Der SPIEGEL hat nach dem klassischen “Stop the press”-Motto nochmal schnell das Cover gewechselt für die morgige Auflage und plakatiert nun die die These des Endes des Atomzeitalters. Find ich gut. Mehr Einzelheiten und Hintergrundinformationen gibt es hier.
