@NASA visualization of sea level changes from 1992-2014! #science

Very cool visualization of sea level change from 1992-2014 from NASA!!

Tomorrow is Earth Day! Celebrate by sharing #NoPlaceLikeHome pictures with @NASA

There are (so far) 1,800 known planets beyond our solar system, but among all of them, there’s no place like Earth. This Earth Day, April 22, NASA is asking you to share pictures and video of your favorite places on Earth using social media – and tag them #NoPlaceLikeHome.

NASA Video – Reflections on Voyager’s Pale Blue Dot #Earth #CarlSagan

NASA Jet Propulsion Laboratory – Reflections on the Pale Blue Dot

Ann Druyan, Carl Sagan’s co-author and widow, reflects on the meaning of Voyager’s “pale blue dot” image of Earth. For more information about the iconic photo taken Feb. 14, 1990, visit http://photojournal.jpl.nasa.gov/cata… and http://go.nasa.gov/1vrTaRo .

More info on the video at NASA here.

Valentine’s Day is special for NASA’s Voyager mission. It was on Feb. 14, 1990, that the Voyager 1 spacecraft looked back at our solar system and snapped the first-ever pictures of the planets from its perch at that time beyond Neptune.

Amazing video from @Space_Station – #sunrise touches #aurora

Another post, another awesome gif from NASA!! This gif (made by CauseScience) shows the aurora borealis in the sky as the sun rises, ending with the two light sources ‘touching’!! The video this gif was made from was taken from the International Space Station – #sunrise touches #aurora. All we need now are angels singing” #AstroButch

Update: The gif CauseScience made from the youtube video is not nearly as good as the vine posted by @Space_Station!

Space lesson of the day: Anything is possible – Asteroid has its own moon!! #space #motivation

NASA Jet Propulsion Laboratory took amazing images of the asteroid that flew past earth Tuesday and discovered it has a ‘moon’! More info here!

The 20 individual images used in the movie were generated from data collected at Goldstone on Jan. 26, 2015. They show the primary body is approximately 1,100 feet (325 meters) across and has a small moon approximately 230 feet (70 meters) across. In the near-Earth population, about 16 percent of asteroids that are about 655 feet (200 meters) or larger are a binary (the primary asteroid with a smaller asteroid moon orbiting it) or even triple systems (two moons). The resolution on the radar images is 13 feet (4 meters) per pixel.

@NASA – 2014 Continues Long-Term Global Warming #ClimateChange

NASA | 2014 Continues Long-Term Global Warming

The year 2014 now ranks as the warmest on record since 1880, according to an analysis by NASA scientists.

This video shows a time series of five-year global temperature averages, mapped from 1880 to 2014, as estimated by scientists at NASA’s Goddard Institute for Space Studies (GISS) in New York.

While scientists expect temperatures to fluctuate from year to year, the average temperature of the planet as a whole has warmed by about 1.4 degrees Fahrenheit (0.8 degrees Celsius) since 1880. This trend is largely driven by increasing human emissions of carbon dioxide and other greenhouse gases into the atmosphere.

The GISS analysis incorporates temperature measurements from 6,300 weather stations around the world, ship- and buoy-based ocean temperature readings and data from Antarctic research stations. These measurements are plugged into an algorithm that then estimates average global temperature. The computer code for this process is freely available for download from the GISS web site.

New video/GIF visualizes waves in Earth’s Ionosphere, 70 miles up!! #supercomputer

Check out this awesome GIF (credit: CauseScience) of Wired.com’s Science Graphic of the Week. The GIF is of a video published in Geophysical Research Letters and shows 3 days of ‘weather’ in the E-layer of the ionosphere, 70 miles up. Check out the Wired.com post for more info here. The video is posted to youtube here, and shows ionospheric gravity waves simulated using NCAR’s Wyoming Super-Computer.

When the Earth’s surface roils with stormy weather, it causes the upper atmosphere to ripple like a breezy pond. Scientists only recently connected the two systems, and a new supercomputer-powered simulation broadens their understanding of how thunderstorms, jet streams, and cyclones affect weather at the edge of space.
