Night lights of Western Europe 🌃⁣ ⁣ In the early morning hours of Aug. 5, 2020, the @noaa -NASA Suomi NPP satellite captured this clear view of Western Europe and its lights (hi, @europeanspaceagency! 👋). The landscape was also well lit by the Moon, which was just one day past full. ⁣ ⁣ Since the launch of the Suomi NPP satellite in late 2011, scientists have been using its Visible Infrared Imaging Radiometer Suite (VIIRS) to provide unprecedented views of Earth at night. This image was acquired through the use of the VIIRS day-night band (DNB), which detects light in a range of wavelengths from green to near-infrared and uses filtering techniques to observe signals such as city lights, wildfires, airglow, and reflected moonlight. ⁣ ⁣ Credit: NASA Earth Observatory image by Joshua Stevens, using VIIRS day-night band data from the Suomi National Polar-orbiting Partnership⁣ ⁣ #nasa #noaa #citylights #nightimages #moonlight

Beautiful Mars! Our Mars Reconnaissance Orbiter with its @uahirise camera launched 15 years ago today. ⁣ ⁣ Since the veteran spacecraft began its mission, it has reshaped our understanding of the Red Planet. The orbiter studies temperatures in Mars' thin atmosphere, peers underground with radar, and detects minerals on the planet's surface. But perhaps what it's become best known for are stunning images. These enhanced color images view Mars in a different part of the spectrum than human eyes would see, to show the distinction between materials and textures. Swipe through for highlights:⁣ ⁣ 1. Sand dunes in the region of Lyot Crater.⁣ 2. A towering dust devil casts a serpentine shadow over the Martian surface. ⁣ 3. Cerberus Fossae, a steep-sided set of troughs cutting volcanic plains to the east of Elysium Mons.⁣ 4. A small frost avalanche in progress at the edge of the North Polar layered deposits of Mars.⁣ 5. Troughs that form a starburst pattern, believed to be formed by gas flowing beneath the seasonal ice to openings where the gas escapes.⁣ 6. Sand ripples and a large dune in Proctor Crater.⁣ ⁣ Credit: NASA/JPL-Caltech/University of Arizona⁣ ⁣ #mars #nasa #geology #solarsystem #dunes

Watch the skies! ☄️ The Perseid meteor shower is here, peaking in the pre-dawn hours of Aug. 12. Perseid meteors, caused by debris left behind by the Comet Swift-Tuttle, began streaking across the skies in late July. The Perseids are best seen between about 2 a.m. your local time and dawn. The Moon rises at around midnight, so its brightness will affect the peak viewing window. However, even though the Moon’s phase and presence will keep the frequency of visible meteors lower, there is still nearly one meteor every two minutes during the peak. A Perseid is seen streaking across the sky in this 30 second exposure, taken on Aug. 13, 2015 in Spruce Knob, West Virginia during the annual meteor shower. Can't get outside? Weather not cooperating? NASA TV has you covered. Tune in starting at 9 p.m. EDT (0100 UTC) through sunrise for a Perseids livestream from our Meteor Watch camera at @nasamarshall: www.nasa.gov/live Credit: NASA/Bill Ingalls #Perseids #meteors #MeteorShower #stargazing #skywatching #nightsky #nasa

"What if we built a bridge, between and above all nations, to jointly discover the galaxy's great unknowns?" Join us this fall as we prepare to celebrate the 20th anniversary of the @ISS. As a global endeavor, 240 people from 19 countries have visited the unique micro gravity laboratory, which has hosted more than 2,800 research investigations from scientists in over 100 nations. #ISS #SpaceStation20th #InternationalSpaceStation #SpaceStation #SpaceExploration #Astronaut #Space

The floor is lava! Oh wait, nevermind, that’s just an infrared look at Jupiter’s North Pole 😉 Our James Webb Space Telescope will examine the atmosphere of Jupiter’s polar region, where @NASAJuno discovered the clusters of cyclones seen in this image. @NASAWebbs data will provide much more detail than has been possible in past observations, measuring winds, cloud particles, gas composition, and temperature.

🔴 On Aug. 9, Mars appears close to the Moon before dawn. Look toward the south, high in the sky, and you can't miss it. ✨ On Aug. 11-12, catch the peak of the annual Perseid meteor shower. Here's when and where to look up! #NASA #NightSky #Planets #LookUpToTheSky

It's the #GlowUp for me! 😍⁣ ⁣ Vast areas of the Mars’ night sky pulse in ultraviolet light as seen in this image from our MAVEN spacecraft, illuminating the complex circulation patterns in the atmosphere.⁣ ⁣ Using green and white false colors to represent the intensity of ultraviolet light, with white being the brightest, the Red Planet takes on a new perspective. ⁣ Intense brightening in Mars’ nightside atmosphere occurs regularly after sunset on Martian evenings during fall and winter seasons, and fade by midnight. The brightening is caused by increased downwards winds which enhance the chemical reaction creating nitric oxide which causes the glow. Nitric oxide is the same chemical that helps give fireflies their glow!⁣ ⁣ Credit: NASA/MAVEN/Goddard Space Flight Center/CU/LASP⁣ ⁣ #Mars #SolarSystem #NASA #Planets #ThatHighlightTho

⚡Looking for a spark in your life? ⁣ ⁣ New results from our Juno mission suggest the planet is home to “shallow lightning.” An unexpected form of electrical discharge, shallow lightning comes from a unique ammonia-water solution. ⁣ ⁣ It was previously thought that lightning on Jupiter was similar to Earth, forming only in thunderstorms where water exists in all its phases – ice, liquid, and gas. But flashes observed at altitudes too cold for pure liquid water to exist told a different story. This illustration uses data obtained by the mission to show what these high-altitude electrical storms look like. ⁣ ⁣ Understanding the inner workings of Jupiter allows us to develop theories about atmospheres on other planets and exoplanets! ⁣ ⁣ Illustration Credit: NASA/JPL-Caltech/SwRI/MSSS/Gerald Eichstädt/Heidi N.
