An Active Prominence on the Sun
Sometimes the Sun’s surface becomes a whirlwind of activity. Pictured is a time-lapse video of the Sun’s surface taken over a two hour period in early May, run both forwards and backwards. The Sun’s surface was blocked out so that details over the edge could be imaged in greater detail. Hot plasma is seen swirling over the solar limb in an ongoing battle between changing magnetic fields and constant gravity. The featured prominence rises about one Earth-diameter over the Sun’s surface. Energetic events like this are becoming less common as the Sun nears a minimum in its 11-year activity cycle. via NASA https://ift.tt/2JX9Luy
Mars Engulfed
What’s happened to Mars? In 2001, Mars underwent a tremendous planet-wide dust storm — one of the largest ever recorded from Earth. To show the extent, these two Hubble Space Telescope storm watch images from late June and early September (2001) offer dramatically contrasting views of the martian surface. At left, the onset of smaller „seed“ storms can be seen near the Hellas basin (lower right edge of Mars) and the northern polar cap. A similar surface view at right, taken over two months later, shows the fully developed extent of the obscuring global storm. Although this storm eventually waned, in recent days a new large dust storm has been taking hold of the red planet. via NASA https://ift.tt/2MzmyFo
Dusty With a Chance of Dust
It’s storm season on Mars. Dusty with a chance of dust is the weather report for Gale crater as a recent planet-scale dust storm rages. On June 10 looking toward the east-northeast crater rim, the Curiosity rover’s Mastcam captured this image of its local conditions so far. Meanwhile over 2,000 kilometers away, the Opportunity rover ceased science operations as the storm grew thicker at its location on the west rim of Endeavour crater, and has stopped communicating, waiting out the storm for now. Curiosity is powered by a radioisotope thermoelectric generator, but the smaller Opportunity rover uses solar panels to charge its batteries. For Opportunity, the increasingly severe lack of sunlight has caused its batteries to run low. via NASA https://ift.tt/2ybKDii

Little Planet Soyuz
Engines blazing, a large rocket bids farewell to this little planet. Of course, the little planet is really planet Earth and the large rocket is a Soyuz-FG rocket. Launched from the Baikonur Cosmodrome in Kazakhstan on June 6 it carried a Soyuz MS-09 spacecraft into orbit. On board were International Space Station Expedition 56-57 crew members Sergey Prokopyev of Roscosmos, Serena Aunon-Chancellor of NASA and Alexander Gerst of ESA. Their spacecraft successfully docked with humanity’s orbiting outpost just two days later.
