Die Erde zwischen den Ringen des Saturn

Ein Blick durch die Ringe des Saturn auf unser Mutterschiff. Das Foto wurde von der Cassini-Sonde aus 1,4 Milliarden Kilometern Entfernung zur Erde aufgenommen. Wer ins Bild reinzoomt kann sogar den Mond erkennen.

The spacecraft captured the view on April 12, 2017, at 10:41 p.m. PDT (1:41 a.m. EDT on April 13). Cassini was 870 million miles (1.4 billion kilometers) away from Earth when the image was taken. Although far too small to be visible in the image, the part of Earth facing Cassini at the time was the southern Atlantic Ocean.

Exoplanet Reise-Poster für Trappist 1


Ihr habt sicher mitbekommen: Astronomen haben sieben Exoplaneten entdeckt, die „nur“ 40 Lichtjahre (wieviele Katzen- bzw. Hundelichtjahre das wohl sind?) von der Erde entfernt um den Zwergstern Trappist-1 kreisen. Drei davon liegen in der habitablen Zone, einer Umlaufbahn, auf der erdähnliches Leben existieren könnte. In Tradition ihrer feinen Space-Travel-Poster (hier Teil 1 & Teil 2) hat die NASA gleich eins für Trappist 1 gepostet (hier in HighRes runterladen). Ich buch dann mal meinen Sommerurlaub…

Some 40 light-years from Earth, a planet called TRAPPIST-1e offers a heart-stopping view: brilliant objects in a red sky, looming like larger and smaller versions of our own moon. But these are no moons. They are other Earth-sized planets in a spectacular planetary system outside our own. These seven rocky worlds huddle around their small, dim, red star, like a family around a campfire. Any of them could harbor liquid water, but the planet shown here, fourth from the TRAPPIST-1 star, is in the habitable zone, the area around the star where liquid water is most likely to be detected. This system was revealed by the TRansiting Planets and PlanetIsmals Small Telescope (TRAPPIST) and NASA’s Spitzer Space Telescope. The planets are also excellent targets for NASA’s James Webb Space Telescope. Take a planet-hopping excursion through the TRAPPIST-1 system.

Innenansicht des Cupola-Moduls der Internationalen Raumstation

Einer der besten Arbeitsplätze der Welt (bzw. im erdnahen Weltraum): Das Cupola-Modul der Internationalen Raumstation mit seiner Konsole für den Robo-Arm (rechtes Fenster). Dazu unsere blaue Murmel im Hintergrund.

This image of the interior view from the International Space Station’s Cupola module was taken on Jan. 4, 2015. The large bay windows allows the Expedition 42 crew to see outside. The Cupola houses one of the space station’s two robotic work stations used by astronauts to manipulate the large robotic arm seen through the right window. The robotic arm, or Canadarm2, was used throughout the construction of the station and is still used to grapple visiting cargo vehicles and assist astronauts during spacewalks. The Cupola is attached to the nadir side of the space station and also gives a full panoramic view of the Earth.

Exoplanet Travel Series – NASA spielt Reisebüro in dreiteiliger Poster-Serie

Die NASA als Reisebüro. Das Angebot umfasst (momentan) drei Poster mit Exoplaneten, die ihr euch in HighRes runterladen könnt. Ich schwanke zwischen Kepler-186f und Kepler-16b – vielleicht hänge ich mir aber auch alle drei auf.


Relax on Kepler-16b – Where your shadow always has company

Like Luke Skywalker’s planet „Tatooine“ in Star Wars, Kepler-16b orbits a pair of stars. Depicted here as a terrestrial planet, Kepler-16b might also be a gas giant like Saturn.

Mal kurz durch die Internationale Raumstation schweben

YouTube: Inside the ISS – 18,000 M.P.H. with Reid Wiseman (via @NASA)

Einmal mit knapp 29.000 km/h von hinten nach vorne durch die ISS schweben mit NASA-Astronaut Reid Wiseman alias @Astro_Reid.

NASA Astronaut Reid Wiseman takes us from the very back of the International Space Station to the front at 18,000 M.P.H. Reid traveled almost 450 miles around the Earth in the 90 seconds it took him to float about 200 feet from one end to the other.

Explosion der Antares-Rakete aus einem Flugzeug in 900 Meter Höhe gefilmt und aus nächster Nähe [Update]

Letzte Nacht ist eine Antares Rakete von Orbital Sciences beim Start explodiert, die im Auftrag der NASA den Raumtransporter Cygnus mit Nachschub für die Internationale Raumstation ISS in den Weltraum bringen sollte. Hier ein Video der Explosion, gefilmt aus einem Kleinflugzeug aus rund 900 Meter Höhe.

I took this video of the very unfortunate Orbital Sciences rocket explosion on my iPad Mini. Video was taken in our Cessna 177 Cardinal from an altitude of 3000ft. Sorry for the sound. I’ll have a better one up once it’s been edited out.

Update: Noch beeindruckenderes Video, aus nächster Nähe von der Presse-Tribüne gefilmt.

Die Erde vom Saturn aus fotografiert


Unsere blaue Kugel (der leuchtende Punkt rechts der Mitte) vor ein paar Tagen aus 1,5 Milliarden Kilometer Entfernung von der Saturn-Sonde Cassini fotografiert und der NASA auf Flickr unter CC BY 2.0 Lizenz veröffentlicht. Die winkenden Menschenmassen sind leider ein bisschen unscharf geworden.

In this rare image taken on July 19, 2013, the wide-angle camera on NASA’s Cassini spacecraft has captured Saturn’s rings and our planet Earth and its moon in the same frame. It is only one footprint in a mosaic of 33 footprints covering the entire Saturn ring system (including Saturn itself). At each footprint, images were taken in different spectral filters for a total of 323 images: some were taken for scientific purposes and some to produce a natural color mosaic. This is the only wide-angle footprint that has the Earth-moon system in it.

The dark side of Saturn, its bright limb, the main rings, the F ring, and the G and E rings are clearly seen; the limb of Saturn and the F ring are overexposed. The „breaks“ in the brightness of Saturn’s limb are due to the shadows of the rings on the globe of Saturn, preventing sunlight from shining through the atmosphere in those regions. The E and G rings have been brightened for better visibility.

Earth, which is 898 million miles (1.44 billion kilometers) away in this image, appears as a blue dot at center right; the moon can be seen as a fainter protrusion off its right side. An arrow indicates their location in the annotated version. (The two are clearly seen as separate objects in the accompanying narrow angle frame: PIA14949.) The other bright dots nearby are stars.

This is only the third time ever that Earth has been imaged from the outer solar system. The acquisition of this image, along with the accompanying composite narrow- and wide-angle image of Earth and the moon and the full mosaic from which both are taken, marked the first time that inhabitants of Earth knew in advance that their planet was being imaged. That opportunity allowed people around the world to join together in social events to celebrate the occasion…
