Space Station Flies Over Super Typhoon Maysak: Typhoon Maysak strengthened into a super typhoon on March 31, reaching Category 5 hurricane status on the Saffir-Simpson Wind Scale. NASA Astronaut Terry Virts captured this image while flying over the weather system on board the International Space Station. Commenting on the storm, Virts wrote, "The eye of #Maysak typhoon really stands out early in the morning with the shadow being cast deep into the vortex." His ESA crewmate on station also viewed the storm and wrote, "Commands respect even from #space: we just flew over typhoon #Maysak."

Hedgerow Prominence Erupts: A tangled mass of plasma strands rose up above the sun in an arch, then quickly fell apart as it broke away into space (Mar. 26-27, 2015). These densely structured prominences, usually unstable, are suspended above the sun by magnetic forces. Here they are imaged in a wavelength of extreme ultraviolet light. Amateur astronomers worldwide have been having a wonderful time watching this event unfold. Image Credit: Solar Dynamics Observatory, NASA #nasa #sun #space #sdo #solar #astronomy #science; -

As the one-year crew, Kelly and Kornienko will return to Earth on Soyuz TMA-18M in March 2016. Image Credit: NASA/Bill Ingalls #nasa #yearinspace #iss #spacestation #astronauts; -
An edge-on view of the spiral galaxy NGC 5023, which lies over 30 million light-years away from us. Due to its orientation seen here by our Hubble Space Telescope, we cannot appreciate its spiral arms, but we can admire the elegant profile of its disk. Astronomers are particularly interested in the vertical structure of disks like these to help understand galaxy evolution. The incredible sharp sight of Hubble has allowed scientist to count more than 30,000 individual bright stars in this image. This is only a small fraction of the several billion stars that this galaxy contains, but the others are too faint to detect individually even with Hubble.

And Lift Off! At 3:42 p.m. EDT, NASA astronaut Scott Kelly and Russian cosmonauts Mikhail Kornienko and Gennady Padalka launched aboard a Soyuz spacecraft to the International Space Station. Kelly and Kornienko will begin a one-year mission in space, testing the limits of human research, space exploration and the human spirit. Most expeditions to the space station last four to six months. By doubling the length of this mission, researchers hope to better understand how the human body reacts and adapts to long-duration spaceflight. This knowledge is critical as NASA looks toward human journeys deeper into the solar system, including to and from Mars, which could last 500 days or longer. It also carries potential benefits for humans here on Earth, from helping patients recover from long periods of bed rest to improving monitoring for people whose bodies are unable to fight infections.

Clues that May Help Identify Dark Matter: Using observations from NASA’s Hubble Space Telescope and Chandra X-ray Observatory, astronomers have found that dark matter does not slow down when colliding with itself, meaning it interacts with itself less than previously thought. Researchers say this finding narrows down the options for what this mysterious substance might be. Dark matter is an invisible matter that makes up most of the mass of the universe. Because dark matter does not reflect, absorb or emit light, it can only be traced indirectly by, such as by measuring how it warps space through gravitational lensing, during which the light from a distant source is magnified and distorted by the gravity of dark matter. Here are images of four different galaxy clusters taken with Hubble (blue) and Chandra (pink) in a study of how dark matter in clusters of galaxies behaves when the clusters collide. A total of 72 large cluster collisions were studied. Image Credit: NASA and ESA #nasa #space #chandra #hubble #hst #hubble25 #astronomy #darkmatter #science; -
Ready to launch astronauts on a one-year mission, the Soyuz TMA-16M spacecraft is seen after having rolled out by train to the launch pad at the Baikonur Cosmodrome, Kazakhstan, Wednesday, March 25, 2015. NASA astronaut Scott Kelly and Russian cosmonauts Mikhail Kornienko and Gennady Padalka of the Russian Federal Space Agency (Roscosmos) are scheduled to launch to the International Space Station in the Soyuz at 3:42 p.m. EDT, Friday, March 27 (March 28, Kazakh time). As the one-year crew, Kelly and Kornienko will return to Earth on the Soyuz TMA-18M in March 2016. This knowledge from the one-year mission is critical as NASA looks toward human journeys deeper into the solar system, including to and from Mars, which could last 500 days or longer.

Fierce black hole "wind" linked to galactic clearing of star-making gas: By combining observations from the Japan-led Suzaku X-ray satellite and the European Space Agency's infrared Herschel Space Observatory, scientists have connected a fierce "wind" produced near a galaxy's monster black hole to an outward torrent of cold gas a thousand light-years across. The finding validates a long-suspected feedback mechanism enabling a supermassive black hole to influence the evolution of its host galaxy. This artist's rendering shows a galaxy being cleared of interstellar gas, the building blocks of new stars. New X-ray observations by Suzaku have identified a wind emanating from the black hole's accretion disk that ultimately drives such outflows. Image Credit: ESA/ATG Medialab; -
Astronaut Terry Virts (@astro_terry) this image from the International Space Station (@ISS) and wrote, "In honor of my friend and fellow fighter pilot "Divot." From above "the surly bonds of earth..." Commander Virts and Flight Engineers Samantha Cristoforetti and Anton Shkaplerov have been in space for 120 days. Monday, Virts and Cristoforetti participated in their 120 day medical tests. The commander conducted a vision test and measurements for the Ocular Health experiment. Cristoforetti collected blood and urine samples for her Biochemical Profile and Bone and Muscle Check. Shkaplerov worked on his set of Russian science experiments.

This view from our Mars Exploration Rover Opportunity shows part of "Marathon Valley," a destination on the western rim of Endeavour Crater, as seen from an overlook north of the valley. The scene spans from east, at left, to southeast. It combines four pointings of the rover's panoramic camera (Pancam) on March 13, 2015, during the 3,958th Martian day, or sol, of Opportunity's work on Mars. The rover team selected Marathon Valley as a science destination because observations yielded evidence of clay minerals, a clue to ancient wet environments. By the time Opportunity explores Marathon Valley, the rover will have exceeded a total driving distance equivalent to an Olympic marathon. Opportunity has been exploring the Meridiani Planum region of Mars since January 2004. Image Credit: NASA #mars #opportunityrover #nasa #martian #journeytomars #science @NASAJPL;

Our Terra Satellite Sees Shadows of Solar Eclipse During the morning of March 20, 2015, a total solar eclipse was visible from parts of Europe, and a partial solar eclipse from northern Africa and northern Asia. NASA's Terra satellite passed over the Arctic Ocean on March 20 at 10:45 UTC (6:45 a.m. EDT) and captured the eclipse's shadow over the clouds in the Arctic Ocean.

Solar Eclipse from Space: Aboard the International Space Station, European Space Agency (ESA) astronaut Samantha Cristoforetti peeked out between experiments and caught this amazing view of the solar eclipse! A solar eclipse occurs when the moon passes between Earth and the sun, casting a shadow over Earth. The moon's shadow masks the solar surface and blocks sunlight from reaching Earth directly - but the amount of sunlight blocked depends on location. For example, on March 20, those in Glasgow, Scotland, saw about 94-percent of the sun blocked by the moon. The unblocked sunlight will appear as a thumbnail sliver. In Paris, the moon blocked about three-quarters of the sun at the time of maximum eclipse.

Arctic sea ice has reached its peak winter extent for the year, and it’s the lowest winter maximum on record. The sea ice cap of the Arctic appeared to reach its annual maximum winter extent on Feb. 25, according to data from the NASA-supported National Snow and Ice Data Center (NSIDC) at the University of Colorado, Boulder. At 5.61 million square miles (14.54 million square kilometers), this year’s maximum extent was the smallest on the satellite record and also one of the earliest.

A strong flare erupted into space from an active region that was roughly facing towards Earth on Mar. 11, 2015. X-class flares are rather uncommon. The bright flash of the flare was followed by streams of dark ejecta that move across the sun to the left. The flare did cause some radio blackouts on Earth when it disturbed our ionosphere. The flare was also associated with a coronal mass ejection. The video clip covers about 2.5 hours. Credit: NASA/SDO;
