How do glaciers turn lakes turquoise? As large, active glaciers push through rocky valleys upstream, they “bulldoze” pulverized rock into fine particles that end up absorbing and scattering sunlight in ways that give lakes a striking blue-green color. Pictured here are lakes from New Zealand’s South Island that stand out for their distinctive turquoise color, as seen in this natural-color satellite image from Landsat 8.

@NASAHubble caught a curious galaxy moving a little closer to us…⁣ ⁣ Because our universe is expanding, almost all of the galaxies we see in the universe are moving away from us. Messier 90, however, appears to be a rare exception.⁣ ⁣ The unusual staircase-like shape of this image is because the camera was made up of four different light detectors, one of which had a higher magnification than the others. In order to combine the images, the high-magnification image needed to be reduced in size.⁣ ⁣ Image credit: ESA/Hubble & NASA, W. Sargent et al.⁣ ⁣ #NASA#Space #HubbleFriday #Galaxy

@NASAHubble spies with its little eye… an irregular galaxy when passing by! ??⁣ ⁣ Earthlings, what you’re looking at is the evidence of two galaxies sideswiping each other millions of years ago, resulting in a galactic hit-and-run. ?? The gravitational tug-of-war between them created rippling patches of higher-density gas and dust within both galaxies. This activity triggered a flurry of star formation.⁣ ⁣ The right side of this galaxy is ablaze with star formation, shown in the plethora of young blue stars and star-incubating pinkish nebulas. ?? This galaxy is a nearby example of the kind of cosmic bumper-car activity that was more common billions of years ago when the universe was smaller and galaxies were closer together. ⁣ ⁣ Image Credit: NASA⁣ ⁣#NASA #Pastels #Galaxy #Stars#HubbleSpaceTelescope#Universe #Nursery

Few of the universe’s residents are as iconic as the spiral galaxy. ? These limelight-hogging celestial objects combine whirling, pinwheeling arms with scatterings of sparkling stars, glowing bursts of gas, and dark, weaving lanes of cosmic dust, creating truly awesome scenes — especially when viewed through the @NASAHubble telescope. Here’s a look at a beautiful spiral galaxy, located 30 million light-years away in the constellation of Leo. This galaxy was studied as part of a Hubble survey that aimed to help astronomers better understand the relationship between the black holes that lurk at the cores of galaxies like these, and the rugby-ball-shaped bulge of stars, gas and dust at the galaxy’s center — such as that seen in this image.

Look closer. You won’t see this majestic view anywhere else. ? After a decade of mapping Earth’s most remote polar landscapes, our Operation IceBridge enters its final year. Using a fleet of research aircraft, the mission studies annual changes in thickness of sea ice, glaciers and ice sheets to better understand connections between polar regions and the global climate system. Now, it will hand the torch over to one of our newest satellite missions, the Ice, Cloud and land Elevation Satellite-2, also known as ICESat-2. From space, ICESat-2 will use take precise measurements of elevation that allows scientists to see where ice is flowing, melting or growing, and to investigate the global impacts of these changes.

When you wish upon a star… Hubble captures it from afar ✨This week our @NASAHubbleSpace Telescope celebrated 29 years of dazzling discoveries, serving as a window to the wonders of worlds light-years away. ⁣ ⁣ Hubble continues to observe the universe in near-ultraviolet, visible, and near-infrared light.

We’re celebrating 29 years since the launch of the @NASAHubbleSpace Telescope with a new look at the Southern Crab Nebula! See the nebula’s hourglass structure ⏳, with bright edges like crab legs ? ? The nebula is located several thousand light-years from Earth and appears to have two nested hourglass-shaped structures that were sculpted by a whirling pair of stars in a binary system. The duo consists of an aging red giant star and a burned-out star, a white dwarf. The red giant is shedding its outer layers. Some of this ejected material is attracted by the gravity of the companion white dwarf. The result is that both stars are embedded in a flat disk of gas stretching between them. This belt of material constricts the outflow of gas so that it only speeds away above and below the disk, forming what looks like an hourglass-shaped nebula.

Specular Spectacular: During its mission, our Cassini spacecraft captured the sun glinting off of Titan’s north polar seas, seen in this near-infrared, color mosaic from August 21, 2014. The sunglint, also called a specular reflection, is the bright area near the 11 o’clock position at upper left. This mirror-like reflection, known as the specular point, is in the south of Titan’s largest sea, Kraken Mare, just north of an island archipelago separating two separate parts of the sea. The southern portion of Kraken Mare displays a “bathtub ring” — a bright margin of evaporate deposits — which indicates that the sea was larger at some point in the past and has become smaller due to evaporation. The deposits are material left behind after the methane & ethane liquid evaporates, somewhat akin to the saline crust on a salt flat.

Gaze in awe: An astronaut aboard the International Space Station (@ISS) snapped this image of the South Indian Ocean as the station flew 265 miles above the cloudy formation. The off-world laboratory orbits the Earth about every 90 minutes and helps us prepare for deep space exploration. The astronaut crews conduct experiments about Earth, space and the physical and biological sciences, benefitting people living on our home planet and future explorers. As a testbed for deep space exploration, the station is helping us learn how to keep astronauts healthy during long-duration space travel and demonstrating technologies for human and robotic exploration beyond low-Earth orbit.
