Ohio Supercomputer Center Researchers Analyse Twitter Posts Revealing Polarization in Congress on COVID-19

Posted by in categories: biotech/medical, government, robotics/AI, supercomputing

June 25, 2020 — The rapid politicization of the COVID-19 pandemic can be seen in messages members of the U.S. Congress sent about the issue on the social media site Twitter, a new analysis found.

Using artificial intelligence and resources from the Ohio Supercomputer Center, researchers conducted an analysis that covered all 30,887 tweets that members sent about COVID-19 from the first one on Jan. 17 through March 31.

Check out this Crew Dragon Photo Snapped During a Spacewalk

Posted by in category: space travel

NASA astronaut Chris Cassidy on Saturday tweeted a cool shot showing SpaceX’s Crew Dragon spacecraft docked with the International Space Station (ISS). The capsule, seen to the right of the picture, looks tiny alongside the enormous space station, but its interior is actually large enough for a human to perform something close to a somersault.

Cassidy captured the image during Friday’s spacewalk with fellow astronaut Bob Behnken. The outing involved ongoing work to upgrade power systems on the space station, swapping old nickel-hydrogen batteries for new lithium-ion batteries. The batteries store power gathered from the station’s main solar arrays and the new ones will provide an improved and more efficient power capacity for the orbiting outpost.

Cassidy later tweeted a couple of other shots from the spacewalk, one a “space selfie” and another taken shortly after the pair returned to the inside of the ISS.

Gorgeous NASA Simulations Show What Sunsets Would Look Like on Other Worlds

Posted by in categories: computing, space

How would the Sun look as it dipped below the horizon on a long (17 hour) day on Uranus? Or what would a late-night sunset on Mars look like, when we finally get there? Thanks to some NASA computer modelling, these scenarios are now a little easier to imagine.

What makes a sunset is the interplay of light from the Sun – which includes all the colours of the rainbow – together with the gases and dust in the atmosphere. The less atmosphere, the less impressive the sunset.

Spectacular New Images Capture the Space Station Cruise Across the Sun

Posted by in category: space

Moving at eight kilometers (five miles) per second, the International Space Station (ISS) circles our planet every 90 minutes. In a 24-hour period, crew members on the ISS experience 16 sunrises and sunsets. Despite how often the station passes directly between Earth and the Sun, capturing an image of the ISS transiting our nearest star is rare.

On June 24, 2020, NASA photographer Joel Kowsky captured such an occurrence from Fredericksburg, Virginia. The image above is a composite, made from six frames, and shows the ISS in silhouette as it moved from right to left across the solar disk while orbiting 400 kilometers (250 miles) above Earth.

The image below shows the position of the ISS in its orbit as Kowsky snapped his photos at approximately 1:15 p.m. U.S. Eastern Daylight Time. The transit lasted approximately 0.54 seconds and was captured while his camera was shooting at 10 frames per second. Watch a video of the transit below.
