Backdropped by the limb of the Earth, a pair of CubeSats are seen moments after being ejected from a small satellite deployer outside of the International Space Station's Kibo laboratory module on Wednesday, May 16, 2017. The tiny shoebox-sized satellites will orbit Earth observing the Earth’s upper atmosphere and interstellar radiation left over from the Big Bang. Over a dozen CubeSats were ejected into Earth orbit this week outside the Kibo module to study Earth and space phenomena for the next one to two years.

In it, you can see a massive counterclockwise rotating storm that appears as a white oven in the gas giant’s southern hemisphere.

Early in the morning on May 19, the Juno spacecraft made its fifth science flyby over these cloud tops, and got as close as about 2,100 miles. Juno is probing beneath the obscuring cloud cover of Jupiter and studying auroras to learn more about the planet’s origins, structure, atmosphere and magnetosphere. At the time of perijove (defined as the point in Juno’s orbit when it is closest to the plent’s center), the spacecraft had logged 63.5 million miles in Jupiter’s orbit.

From 36,000 nautical miles away, this full disk view of our home planet shows the crew’s vantage point from space.

The crew members on Apollo 10 were astronauts Thomas P. Stafford, commander; John W. Young, command module pilot; and Eugene E. Cernan, lunar module pilot. Astronaut Young remained in lunar orbit, in the Command and Service Module (CSM) Using a fleet of research aircraft, our Operation IceBridge images Earth's polar ice to better understand connections between polar regions and the global climate system. IceBridge studies annual changes in thickness of sea ice, glaciers and ice sheets. IceBridge bridges the gap between the IceSat missions.

Seen here is a time-lapse view of a glacier-run from the cockpit of our P-3 Orion aircraft taken during a May 8, 2017 flight over Greenland's Southeast glaciers.

This will continue until the solstice later this month. Then, the shadow will extend only as far as the innermost A ring. 
The image was taken in visible light with the Cassini spacecraft wide-angle camera on Feb. 3, 2017. The view was acquired at a distance of approximately 760,000 miles (1.2 million kilometers) from Saturn.

Prominences are notoriously unstable. Competing magnetic forces pulled the plasma back and forth until they dissipated. The images were taken in a wavelength of extreme ultraviolet light. The 18-second video clip is comprised of almost 600 frames being shown at 30 frames per second.

#nasa #space #solar #sun #sdo #solarobservatory #spacecraft #magneticfield #particles #energy Although appearing as one object, this image shows two galaxies rushing past each other at about 1,243,000 miles per hour! This speed is most likely too fast for them to merge and form a single galaxy. However, because of their small separation of only about 20,000 light-years, the galaxies will distort one another through the force of gravity while passing each other, changing their structures on a grand scale.

Such galactic interactions are a common sight for Hubble, and have long been a field of study for astronomers. The intriguing behaviors of interacting galaxies take many forms; galactic cannibalism, galaxy harassment and even galaxy collisions. The Milky Way itself will eventually fall victim to the latter, merging with the Andromeda Galaxy in about 4.5 billion years. The fate of our galaxy shouldn’t be alarming though: while galaxies are populated by billions of stars, the distances between individual stars are so large that hardly any stellar collisions will occur.

Tomorrow, is Fischer’s first-ever spacewalk and the 200th on the International Space Station. He’ll be joined in the vacuum of space by fellow astronaut Peggy Whitson. For her, this is spacewalk number nine. 
Once both astronauts venture outside, their tasks will focus on replacing a large avionic box that supplies electricity and data connections to the science experiments and rigging a new high-definition camera to the outside of station.

Swipe to explore the wavelengths! The view starts with a composite image of the Crab Nebula, a supernova remnant that was assembled by combining data from five telescopes spanning nearly the entire breadth of the electromagnetic spectrum: the Very Large Array, the Spitzer Space Telescope, the Hubble Space Telescope, the XMM-Newton Observatory, and the Chandra X-ray Observatory. 
It then moves to the red-colored radio-light view that shows how a neutron star’s fierce “wind” of charged particles from the central neutron star energized the nebula, causing it to emit the radio waves. 
The yellow-colored infrared image includes the glow of dust particles absorbing ultraviolet and visible light. 
The green-colored Hubble visible-light image offers a very sharp view of hot filamentary structures that permeate this nebula. 
The blue-colored ultraviolet image and the purple-colored X-ray image shows the effect of an energetic cloud of electrons driven by a rapidly rotating neutron star at the center of the nebula.

The sunlight falling on Saturn’s north pole, which is just enough to allow us to image and study the region, does not provide much warmth. In addition to being low in the sky (just like summer at Earth's poles), the sun is nearly ten times as distant from Saturn as from Earth and is only about 1 percent as intense as on Earth.
