NASA Television to Air Launch of Next Planet-Hunting Mission

On a mission to detect planets outside of our solar system, NASA’s Transiting Exoplanet Survey Satellite (TESS) is scheduled to launch no earlier than 6:32 p.m. EDT Monday, April 16. Prelaunch mission coverage will begin on NASA Television and the agency’s website Sunday, April 15, with three live briefings.

The Sun Unleashed: Monster Filament in Ultraviolet

One of the most spectacular solar sights is an explosive flare. In 2011 June, the Sun unleashed somewhat impressive, medium-sized solar flare as rotation carried active regions of sunpots toward the solar limb. That flare, though, was followed by an astounding gush of magnetized plasma — a monster filament seen erupting at the Sun’s edge in this extreme ultraviolet image from NASA’s Solar Dynamics Observatory. Featured here is a time-lapse video of that hours-long event showing darker, cooler plasma raining down across a broad area of the Sun’s surface, arcing along otherwise invisible magnetic field lines. An associated coronal mass ejection, a massive cloud of high energy particles, was blasted in the general direction of the Earth,and made a glancing blow to Earth’s magnetosphere. via NASA https://ift.tt/2qiokjX

Painting with Jupiter

Brush strokes of Jupiter’s signature atmospheric bands and vortices form this planetary post-impressionist work of art. The creative image uses actual data from the Juno spacecraft’s JunoCam. To paint on the digital canvas, a image with light and dark tones was chosen for processing and an oil-painting software filter applied. The image data was captured during perijove 10, Juno’s December 16, 2017 close encounter with the solar system’s ruling gas giant. At the time the spacecraft was cruising about 13,000 kilometers above northern Jovian cloud tops. via NASA https://ift.tt/2qblm1n

Hubble Finds an Einstein Ring

These graceful arcs are a cosmic phenomenon known as an Einstein ring – created as the light from distant galaxies warps around an extremely large mass, like a galaxy cluster. via NASA https://ift.tt/2JrIFMa
