SDO Saw Only a Partial Eclipse



Millions of excited people in the U.S. traveled many miles see a total eclipse, and what a show it was. The SDO spacecraft was not so fortunate: its orbit only allowed it to observe a partial eclipse that at its peak covered only about 14 per cent of the sun (Aug. 21, 2017).

Most of the people in the U.S. (weather permitting) observed at least 60 per cent coverage of the sun by the Moon. The good news for SDO is that it gets to see partial and solar eclipses several times a year. So, it all kind of balances out, in a way.

Oregon Wildfire in Eclipse Zone Imaged by NASA Satellite



The Whitewater Fire in the Mount Jefferson Wilderness in Oregon was started by a lightning strike. As of Aug. 18, 2017, more than 117,000 acres and 30 miles (48 kilometers) of the Pacific Crest Trail are closed to the public in an area that had been expected to be popular with people there to view the August 21 solar eclipse.

The smoke clouds sit over the burned area, just west-northwest of Mount Jefferson. The image was acquired Aug. 18, 2017, covers an area of 16 by 17 miles (26.1 by 27.2 kilometers), and is located at 44.7 degrees north, 121.8 degrees west.

Hubble's Megamaser Galaxy




MCG+01-38-005 (below) is a special kind of megamaser; the galaxy’s active galactic nucleus pumps out huge amounts of energy, stimulating clouds of surrounding water.

Hurricane Harvey Flooding Seen in New NASA Satellite Image



On Sept. 5, 2017, the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) instrument on NASA's Terra spacecraft captured this image of the area around Bay City, Texas, about 50 miles (80 kilometers) southwest of Houston.

Hurricane Harvey caused extensive inland flooding, seen as dark blue areas where the water is relatively clear, and green-grey where the water carries sediment.

The image covers an area of 32 by 65 miles (52 by 105 kilometers), and is centered at 29.2 degrees north, 95.8 degrees west.

Hurricane Irma, a record Category 5 storm, is seen in this NOAA National Weather Service National Hurricane Center image from GOES-16 satellite taken on September 5, 2017.

Irma strengthened to a Category 5 hurricane Tuesday with winds up to 185 mph. The storm is most powerful ever recorded in the Atlantic Ocean. It’s so strong it is even showing up on scales for measuring earthquakes.

Here is another perspective of Irma. The arrows show winds at the surface, graded from green to red.

The GPM satellite's DPR (shown in lighter shades) uncloaked precipitation that was falling at a rate of more than 10.8 inches (274 mm) per hour in the solid ring of powerful storms within Irma's eye wall. These extreme storms were reaching heights of over 10.0 miles (16.2 km).




NASA-NOAA’s Suomi NPP satellite captured this night-time image of Hurricane Irma over the Leeward Islands on Sept. 6 at 1:35 a.m. EDT (0535 UTC).

Jupiter's Auroras Acceleration Processes



This image, created with data from Juno's Ultraviolet Imaging Spectrometer (UVS), marks the path of Juno's readings of Jupiter's auroras, highlighting the electron measurements that show the discovery of the so-called discrete auroral acceleration processes indicated by the "inverted Vs" in the lower panel.

This signature points to powerful magnetic-field-aligned electric potentials that accelerate electrons toward the atmosphere to energies that are far greater than what drive the most intense aurora at Earth. Scientists are looking into why the same processes are not the main factor in Jupiter's most powerful auroras.

A large sunspot was the source of a powerful solar flare (an X 9.3) and a coronal mass ejection (Sept. 6, 2017). The flare was the largest solar flare of the last decade. For one thing, it created a strong shortwave radio blackout over Europe, Africa and the Atlantic Ocean.

Sunspot 2673 has been also the source of several other smaller to medium-sized solar flares over the past few days. Data from the SOHO spacecraft shows the large cloud of particles blasting into space just after the flare.

Note: the bright vertical line and the other rays with barred lines are aberrations in our instruments caused by the bright flash of the flare.

NASA's Cassini spacecraft gazed toward the northern hemisphere of Saturn to spy subtle, multi-hued bands in the clouds there.

Space is big. You just won't believe how vastly, hugely, mind- bogglingly big it is. I mean, you may think it's a long way down the road to the chemist's, but that's just peanuts to space. - Douglas Adams in 'The Hitchhiker's Guide to the Galaxy'
