Jupiter's Bands of Clouds

This enhanced-color image of Jupiter's bands of light and dark clouds was created by citizen scientists Gerald Eichstädt and Seán Doran using data from the JunoCam imager on NASA's Juno spacecraft.

Three of the white oval storms known as the "String of Pearls" are visible near the top of the image. Each of the alternating light and dark atmospheric bands in this image is wider than Earth, and each rages around Jupiter at hundreds of miles (kilometers) per hour. The lighter areas are regions where gas is rising, and the darker bands are regions where gas is sinking.

Juno acquired the image on May 19, 2017, at 11:30 a.m. PST (2:30 p.m. EST) from an altitude of about 20,800 miles (33,400 kilometers) above Jupiter's cloud tops.

The White Cliffs of "Rover"

This image from NASA's Mars Reconnaissance Orbiter is reminiscent of the rugged and open terrain of a stark shore-line, perhaps of an island nation, such as the British Isles. A close-up in enhanced color produces a striking effect, giving the impression of a cloud-covered cliff edge with foamy waves crashing against it.

The reality is that the surface of Mars is much dryer than our imaginations might want to suggest. This is only a tiny part of a much larger structure; an inverted crater -- a crater that has been infilled by material that is more resistant to erosion than the rocks around it -- surrounded by bluish basaltic dunes. The edge of these elevated light-toned deposits are degraded, irregular and cliff-forming.

Dunes visible below the cliff, give the impression of an ocean surface, complete with foam capped waves crashing against the "shore line," demonstrating the abstract similarity between the nature of a turbulent ocean and a Martian dune field.

Meridiani Planum has an overall smooth terrain, which starkly contrasts with the more common boulder- and crater-laden landscapes observed over much of the rest of Mars. This makes it relatively younger in character than many other areas of the planet. Meridiani is one of the Mars Exploration Rover landing sites, and, is known for its layers and sediments. The orbital detection of hematite was one of the main reasons for sending Opportunity to this area.

Salt-bearing rocks -- also called sulphates -- were observed in the very first image from Opportunity, so perhaps it's apt that this HiRISE image reminds us of the turmoil and rugged beauty of a cliff-face, a coastline, being worn down by a relentless sea.

The map is projected here at a scale of 50 centimeters (19.7 inches) per pixel. [The original image scale is 54.7 centimeters (21.5 inches) per pixel (with 2 x 2 binning); objects on the order of 164 centimeters (64.6 inches) across are resolved.] North is up.

The University of Arizona, Tucson, operates HiRISE, which was built by Ball Aerospace & Technologies Corp., Boulder, Colo. NASA's Jet Propulsion Laboratory, a division of Caltech in Pasadena, California, manages the Mars Reconnaissance Orbiter Project for NASA's Science Mission Directorate, Washington.

A Crater on a Crater Wall

NASA's Mars Reconnaissance Orbiter (MRO) observes a small impact has occurred on the sloping wall of a larger crater and is well-preserved. Dark, blocky ejecta from the smaller crater has flowed downhill (to the west) toward the floor of the larger crater

What’s New In Social: Facebook Live Broadens Audience With Closed Captions

What?

Facebook Live allows publishers to include closed captions in their broadcast.

Why?

Facebook is aggressively investing in live video. As live broadcasting increases in popularity and availability, accessibility for deaf or hard of hearing audiences will impact niche target audiences. This new update can provide accessibility about 30 million people. The National Institute of Deafness estimates 13 percent, or 30 million people in the United States aged 12 years or older has hearing loss in both ears.

Industries likely to benefit?

Major League Sports brands will be the immediate beneficiaries of this update. Expect to see closed captions during the upcoming baseball season when Facebook live broadcasts 20 Friday Major League Baseball (MLB) games. The Global esports company ESL is also likely to immediately benefit from closed captions. Last month, Facebook partnered with ESL to bring 5,550 hours of esports events and other original content to Facebook.

In addition to sports entities, a new category of digital businesses will be created to meet the increased demand for closed captioning. Forward thinking advertising agencies will create in-house tools and offer them to clients as add-ons or a ‘bonus’ service as a means to capture data.

Flaring Red Dwarf Star

A South Polar Pit or an Impact Crater?

This observation from NASA's Mars Reconnaissance Orbiter shows it is late summer in the Southern hemisphere, so the Sun is low in the sky and subtle topography is accentuated in orbital images.

What’s New In Social: Twitter Adds Direct Message Request Review Feature

What?

Twitter’s newest update includes a Direct Message request review inbox. Twitter accounts with settings enabled to “Receive messages from anyone” will see incoming messages from people without a direct connection appear as "Requests" in the "Messages" tab. Group conversations included with people who are not followed by the account will also appear in "Requests". Accepting the message request will allow you to engage with the sender and will move the message to your inbox.

Why?

This update is another attempt to improve the Twitter user experience and encourage people to communicate via Direct Messages. The ability to view media prior to accepting a message will help prevent unwanted communication and surprises from viewing unexpected inappropriate images or videos.

Industries likely to benefit?

A direct message review feature is unlikely to move the needle for brands or individuals. The possible benefit of increased time spent on Twitter will be incremental and immeasurable.
