NASA’s Curiosity Mars rover has reached an area where orbital images had piqued researchers’ interest in patches of ground with striations all oriented in a similar direction.
A close-up look at some of the striations from the rover’s Navigation Camera gains extra drama by including Mount Sharp in the background. The lower slopes of that layered mountain are the mission’s long-term science destination. The image is online at: (more…)
The closest supernova of its kind to be observed in the last few decades has sparked a global observing campaign involving legions of instruments on the ground and in space, including NASA’s Spitzer Space Telescope. With its dust-piercing infrared vision, Spitzer brings an important perspective to this effort by peering directly into the heart of the aftermath of the stellar explosion.
Dust in the supernova’s host galaxy M82, also called the “Cigar galaxy,” partially obscures observations in optical and high-energy forms of light. Spitzer can, therefore, complement all the other observatories taking part in painting a complete portrait of a once-in-a-generation supernova, which was first spotted in M82 on Jan. 21, 2014. A supernova is a tremendous explosion that marks the end of life for some stars. (more…)
NASA is partnering with the California Department of Water Resources (DWR) to develop and apply new technology and products to better manage and monitor the state’s water resources and respond to its ongoing drought.
NASA scientists, DWR water managers, university researchers and other state resource management agencies will collaborate to apply advanced remote sensing and improved forecast modeling to better assess water resources, monitor drought conditions and water supplies, plan for drought response and mitigation, and measure drought impacts.

Roguish runaway stars can have a big impact on their surroundings as they plunge through the Milky Way galaxy. Their high-speed encounters shock the galaxy, creating arcs, as seen in this newly released image from NASA’s Spitzer Space Telescope.
In this case, the speedster star is known as Kappa Cassiopeiae, or HD 2905 to astronomers. It is a massive, hot supergiant moving at around 2.5 million mph relative to its neighbors (1,100 kilometers per second). But what really makes the star stand out in this image is the surrounding, streaky red glow of material in its path. Such structures are called bow shocks, and they can often be seen in front of the fastest, most massive stars in the galaxy. (more…)
Using images from NASA’s Voyager Mission (1979) and the orbital Galileo Mission (1995), researchers have created the first global geological map of Jupiter’s largest moon, Ganymede.
PROVIDENCE, R.I. [Brown University] — Scientists, including Brown University geologists and students, have completed the first global geological map of Ganymede, Jupiter’s largest moon and the largest in the solar system. (more…)
One of the biggest mysteries in astronomy, how stars blow up in supernova explosions, finally is being unraveled with the help of NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR).
The high-energy X-ray observatory has created the first map of radioactive material in a supernova remnant. The results, from a remnant named Cassiopeia A (Cas A), reveal how shock waves likely rip apart massive dying stars. (more…)
In einer genau ausbalancierten günstigen Entfernung von seinem Stern, mit Wasser auf der Oberfläche, so sollte der Planet sein, den die Wissenschaftler der PLATO-Mission außerhalb unseres Sonnensystems entdecken wollen. Unter der Leitung des Deutschen Zentrums für Luft- und Raumfahrt (DLR) wird ein internationales Konsortium sich auf die Suche nach dieser zweiten Erde machen. 2024 soll das Weltraumteleskop starten, das die Europäische Weltraumorganisation ESA am 19. Februar 2014 unter fünf vorgeschlagenen Missionen ausgewählt hat. “Wir werden Planeten finden, die ihren sonnenähnlichen Stern in der lebensfreundlichen, der habitablen Zone umkreisen: Planeten, auf deren Oberfläche Wasser vorhanden sein könnte und auf denen dann vielleicht sogar die Entwicklung von Leben, wie wir es kennen, möglich wäre”, sagt Prof. Heike Rauer vom DLR-Institut für Planetenforschung , die das PLATO-Instrumentenkonsortium leitet.

Die Uhr tickt: In 100 Tagen wird der deutsche ESA-Astronaut Alexander Gerst zur Internationalen Raumstation ISS starten – gemeinsam mit seinen Kollegen, dem NASA-Astronaut Reid Wiseman und dem russischen Kosmonauten Maxim Surajew.
An Bord einer Sojus-Trägerrakete werden 274 Tonnen Treibstoff sie auf 28.000 Stundenkilometer beschleunigen. Damit werden Sie den orbitalen Außenposten der Menschheit in weniger als sieben Stunden erreichen. Der für den 28. Mai 2014 geplante Start ist der Beginn von Alexanders sechsmonatiger Mission “Blue Dot” als Teil der ISS Expedition 40/41. (more…)
