A galaxy so faint you can barely see it ✨ @NASAHubble Space Telescope recently caught a glimpse of a galaxy 30 million light-years away. UGC 695 has so few stars that its brightness is less than the background brightness of Earth’s atmosphere — making it difficult to observe. Thankfully, Hubble managed to take a peek for us.

No, this isn’t a firework. 🎆 You are looking at a flame and the glowing soot clusters it produced aboard the International Space Station (@ISS). These yellow soot clusters grow larger than those on Earth, because they stay inside the flame longer in microgravity. This flame was one of many ignited inside a combustion research facility to investigate the amount of soot that is produced in different conditions. Soot is the carbon residue left behind when organic matter (or other carbon-containing material) doesn’t fully burn. It causes environmental and health issues, but can be helpful in multiple ways, including by enhancing radiant heat. This experiment could allow the design of flames that are more sooty or soot-free. These results may help create burner designs which are more efficient and less polluting. Credit: NASA

At the North Pole of Mars, springtime is avalanche season! ⁣ ⁣ The @UAHiRISE camera on our Mars Reconnaissance Orbiter spacecraft captured this cloud of dust on May 29, 2019, as melting ice blocks broke loose and tumbled down a cliff face over 1600 feet (500 meters) tall. ⁣ ⁣ Image Credit: NASA/JPL/University of Arizona⁣ ⁣

Greenland is where it’s at. ⁣⁣ ⁣⁣ And by “it,” we mean three of our different ice measuring missions — Operation , Oceans Melting Greenland (OMG) and the Airborne Visible/Infrared Imaging Spectrometer (AVIRIS). ⁣⁣ ⁣⁣ IceBridge is in Greenland beginning a series of flights to measure sea ice and land ice during the summer melt season. OMG is studying the ocean’s effect on the island’s melt and AVIRIS is verifying how the satellite ’s lasers are working to see melty ice. ⁣⁣ ⁣⁣ In the last image, you can see all three planes meeting on the runway. ⁣⁣ ⁣⁣ Image 1 & 2: Linette Boisvert/NASA⁣⁣ Image 3 & 4: John Sonntag/NASA⁣⁣ Image 5: Eugenia de Marco/NASA⁣⁣ ⁣⁣

Look! A cosmic block party 🥳 ⁣ ⁣ In this Hubble image, you’ll find 50 spiral and dwarf galaxies hanging out in our cosmic neighborhood. ⁣ ⁣ The main focal point of stars is actually a dwarf galaxy. Dwarf galaxies often show a hazy structure, an ill-defined shape and an appearance somewhat akin to a swarm or cloud of stars — and UGC 685 is no exception to this. ⁣ ⁣ These data were gathered under Hubble’s Legacy ExtraGalactic UV Survey (LEGUS) program, the sharpest and most comprehensive ultraviolet survey of star-forming galaxies in the nearby universe. ⁣ ⁣ Image Credit: ESA/Hubble & NASA; the LEGUS team, B. Tully, D. Calzetti⁣ ⁣

Dust in this galaxy is bathed by ultraviolet and visible light from nearby stars. ✨ ⁣ ⁣ M81 is located in the northern constellation of Ursa Major 12 million light-years away from us — easily visible through binoculars or a small telescope. ⁣ ⁣ This Spitzer Space Telescope infrared image is a composite mosaic combining data from the Infrared Array Camera with data from the Multiband Imaging Photometer.⁣ ⁣ Click the link in the bio for more info ⬆️⁣ Image Credit: NASA/JPL-Caltech⁣ ⁣

The final stages of a star’s life allow us a glimpse into the future of our own solar system. 🌟 ⁣⁣ ⁣⁣ This image from @NASAHubble shows what’s left of a star 10,000 light-years from Earth. ⁣⁣ ⁣⁣ A star like our Sun will, at the end of its life, transform into a red giant. The core of the star will eventually collapse in on itself, ejecting the surface layers outward. After that, all that remains of the star is what we see here: glowing outer layers surrounding a white dwarf star. ⁣ ⁣ Click the link above for more info ⬆️⁣ ⁣⁣ Image credit: ESA/Hubble & NASA, R.

From the vantage point of 250 miles above Earth, astronauts aboard the International Space Station (@ISS) captured these views of on Sept 2. Now a high category 2 hurricane, the storm is beginning to move northwestward.⁣ ⁣ Following a hurricane’s landfall, flooding and power outages are mapped using @NOAA and @NASAEarth satellites. Having data on the various factors of a severe storm can help first responders and recovery efforts. ⁣ ⁣ Stay safe and visit our hurricane blog for updates: https://go.nasa.gov/Dorian ⁣ ⁣ Image Credit: NASA/ESA ⁣ ⁣

🌀Here’s a view of from space. ⁣ From 260 miles in altitude, cameras outside the International Space Station (@ISS) captured this view at 11:27 a.m. EDT on Sept. 2 as the storm churned over northwestern Bahamas.⁣ ⁣ Although gradual weakening is forecast, Dorian is expected to remain a powerful hurricane during the next couple of days while moving on a possible track up the southeastern U.S. seaboard. ⁣ ⁣ Credit: NASA⁣ ⁣

Celebrate Spitzer's Super Sweet 16! 🎂⁣ ⁣ Since 2003, our Spitzer Space Telescope has been lifting the veil on the wonders of the cosmos, from our own solar system to faraway galaxies, using infrared light! ✨💫⭐️⁣ ⁣ Thanks to Spitzer, we've confirm the presence of seven rocky, Earth-size planets, received weather maps of hot, gaseous exoplanets and discovered a hidden ring around Saturn. ⁣ ⁣ 🥳 In honor of Spitzer's Sweet 16 in space, enjoy 10 jaw-dropping images from its mission. Check out our link in bio for more on these discoveries! ⁣ ⁣

🌀As Hurricane Dorian continues its move towards land, satellite missions from NASA and @NOAA are keeping an eye on the storm from space. After brushing past Puerto Rico, the storm began intensifying over open waters. On Aug. 29, forecasters noted: “Strengthening is forecast during the next few days, and Dorian is expected to become a major hurricane on Friday, and remain an extremely dangerous hurricane through the weekend.” Seen here is a composite image of the strengthening storm from the GOES-16 satellite. This simulated natural color image comes from the weather satellite’s Advanced Baseline Imager. GOES-16 is operated by the National Oceanic and Atmospheric Administration (NOAA). NASA helps develop and launch the GOES series of satellites. Image credit: NASA/NOAA/NESDIS

What remains after a star explodes 💥 ? A brightly glowing field of debris, expanding outward into space.⁣ ⁣ This supernova remnant, Cassiopeia A or Cas A, was imaged by our Chandra X-ray Observatory (@nasachandraxray). It's located about 11,000 light years from Earth and was also featured in Chandra's "first light" image at the start of the mission in 1999. This recent study of Cas A adds to a long collection of Chandra discoveries over the course of the telescope’s 20 years. In addition to finding the central neutron star, Chandra data have revealed the distribution of elements essential for life ejected by the explosion, clues about the details of how the star exploded, and much more.⁣ ⁣ Image credit: X-ray: NASA/CXC/RIKEN/T.

August 2019 is continuing an active Amazon fire season, with large and intense fires burning in the region. NASA satellites tracked actively burning fires across South America and captured images of smoke in the last week. So far, in 2019, the region is experiencing more fires, with more intense burns, than in recent years.⁣⁣ ⁣ Credits: NASA Earth Observatory images by Joshua Stevens, using MODIS data from NASA EOSDIS/LANCE and GIBS/Worldview, Fire Information for Resource Management System (FIRMS) data from NASA EOSDIS, and data from the Global Fire Emissions Database (GFED).⁣ ⁣⁣ ⁣⁣ ⁣

What's it like to step out into space for your third spacewalk? "Each time I open the door the views keep getting better." 🤩⁣ ⁣ Astronaut Nick Hague, along with fellow crew member Andrew Morgan, worked outside the International Space Station (@ISS) for 6 hours and 32 minutes yesterday. They installed the station's second docking port for commercial crew spacecraft — which will be used by the @SpaceX Dragon and @Boeing Starliner spacecrafts when they carry astronauts to the station.⁣ ⁣ ⁣ Image Credit: NASA

The Bahamas from space! The vivid colors make this one of the most recognizable places on Earth for astronauts. Astronaut Luca Parmitano of @europeanspaceagency took the latest photo of the islands from the International Space Station (@ISS) on Aug. 21, 2019.

What do you see in the clouds? ☁️☁️☁️ ⁣ ⁣ These spiraling cloud patterns off the coast of Morocco were captured by our @NASAEarth instrument on the Suomi NPP satellite on July 19, 2019. They're known as von Kármán vortices, which can form nearly anywhere that fluid flow is disturbed by a solid object. Here, the patterns formed when winds flowed around small islands in the North Atlantic.⁣ ⁣ Credit: NASA Earth Observatory image by Joshua Stevens, using VIIRS day-night band data from the Suomi National Polar-orbiting Partnership. ⁣ ⁣

A Spacecraft Duo! The @NorthropGrumman Cygnus and @SpaceX Dragon spacecrafts are seen in this August 6 view from the International Space Station (@ISS). The Cygnus resupply spacecraft is shown grappled by the robotic arm following its detachment from its docking port on the orbiting outpost and just before release. Behind the robotic arm, the Dragon is seen still attached to the station. Both spacecraft are currently re-supplying the orbiting laboratory with science and supplies to support the crew.

This rounded object isn't something seen through a microscope. Instead, it's a vast orb of gas in space, cast off by an aging star and seen by the @NASAHubble telescope. The star is visible in the orb's center, shining through the gases it formerly held onto for most of its stellar life. When stars like the Sun grow advanced in age, they expand and glow red. These so-called red giants then begin to lose their outer layers of material into space. More than half of such a star's mass can be shed in this manner, forming a shell of surrounding gas. At the same time, the star's core shrinks and grows hotter, emitting ultraviolet light that causes the expelled gases to glow. Image credit: ESA/Hubble & NASA, R. Wade

Flying through a fire cloud ☁️🔥☁️⁣⁣⁣ ⁣⁣⁣ This photo from roughly 30,000 ft (9 km) shows how smoke particles reflect light in ways that make the Sun appear blazing orange. Our DC-8 flying laboratory passed directly through a large fire cloud — called a pyrocumulonimbus — on August 8 as it was rising from a fire in eastern Washington, giving scientists a look at the phenomena. These clouds form when the intense heat of wildfires lift the smoke above the boundary layer, the lowest part of Earth's atmosphere.⁣⁣⁣ ⁣⁣⁣ The flight was part of a joint NOAA and NASA field campaign called FIREX-AQ. Scientists are studying the composition and chemistry of smoke in the atmosphere to better understand its impact on air quality and climate.⁣⁣⁣ ⁣⁣ NASA Earth Observatory image credit: NASA/Joshua Stevens⁣⁣ Photography credits: U.S. Naval Research Laboratory/David Peterson⁣⁣ ⁣⁣⁣

A full Moon is seen as the International Space Station (@ISS) flew 270 miles above the South Pacific Ocean off the coast of South America. The space station is an international partnership of the space agencies of the United States, Russia, Europe, Japan and Canada. In addition to photographs of the beautiful planet we call home, the Space Station functions as cooperative international laboratory, the work of which benefits all humanity.

As the @NASAHubble telescope turned its eye on Jupiter’s Great Red Spot, an Earth-sized storm rolling counterclockwise between two bands of clouds, it noticed something unusual. Can you tell what it is? 🤔⁣ ⁣ The color palette in the clouds is more intense than usual. The colorful bands, which flow in opposite directions at various latitudes, result from different atmospheric pressures. Lighter bands rise higher and have thicker clouds than the darker bands. The intensity of the colors reveals important clues about the planet’s turbulent atmosphere. ⁣ ⁣ Click the link in the bio for more info ⬆️⁣ ⁣ Credits: NASA, ESA, A.
