the most recent flight of our sofia flying observatory brought the team so far south that they spotted the southern lights, also known as aurora australis. the milky way and mars are also visible in this image taken at 43,000 feet.
the sofia telescope (@sofiatelescope) uses an outfitted boeing 747sp jetliner that’s been modified to carry a 106-inch diameter telescope, and uses infrared light to study celestial objects best viewed from the southern hemisphere. the latest flight was aimed at studying the center of the milky way and the tarantula nebula.
creating images of the celestial magnetic fields found in the center of our milky way galaxy will help scientists better understand the shape and strength of these fields and gain new insights into how they impact the processes in the our galactic center.
mapping the tarantula nebula, which has a cluster of thousands of stars forming at once, will help researchers determine the speed and direction of the molecules in the nebula to determine if the material is expanding, forming new stars or if the star formation process has been stunted.

how would you go about finding the brightest, distant galaxies possible? for our hubble space telescope (@nasahubble) team, they are looking at 41 massive galaxy clusters to find the celestial objects for the upcoming webb space telescope (@nasawebb) to study. this new sparkling view shows one of the clusters of galaxies along with a few homeless stars.
the enormous gravitational influence of such clusters distorts the space around them in such a way that they can be used as giant cosmic lenses that magnify distant background galaxies. studying some of the earliest galaxies in the universe will tell us more about our cosmic origins.

bang and whoosh! when a meteoroid hit the surface of mars and exploded to make this crater, it also destabilized the slope and initiated the avalanche seen here by our mars reconnaissance orbiter. while the crater itself is only five meters across, the slope streak it started is one kilometer long!

mars is infamous for intense dust storms. right now, a massive martian dust storm is affecting operations of our opportunity rover. this storm is already one of the most intense ever observed on the red planet. the storm, which was first detected by our mars reconnaissance orbiter on may 30, has grown to cover more than 15.8 million square miles (41 million square kilometers) as of june 10 – an area about the size of north america and russia combined. it has blocked out so much sunlight, it has effectively turned day into night for opportunity, which is located near the center of the storm, inside mars' perseverance valley.
these two views from our mars curiosity rover, acquired specifically to measure the amount of dust inside gale crater, show that dust has increased over three days from a major martian dust storm. in the first image, we see a view of the east-northeast rim of gale crater on june 10, 2018 (sol 2077). swipe to see a view of the same feature on june 7, 2018 (sol 2074), three days earlier. the images were taken by the rover's mastcam.

as air traffic continues to surge in the u.s., neighbors who live near airports are complaining about the escalating noise. all the while, the demand for faster aircraft that travel at supersonic speeds is accelerating.
to address the expected noise levels of future aircraft, our commercial supersonic technology project is already developing technologies focused on reducing the noise produced by an aircraft’s engine exhaust.
acoustics experts at our glenn research center (@nasaglenn) in cleveland recently used the center’s aero-acoustic propulsion laboratory to complete an evaluation on a small-scale model of a learjet engine exhaust, or nozzle, system.
the blue, curved array at the top of the dome held microphones for making the noise measurements and simulating a flyover. the large door to the right was opened to exhaust the air from the jet during tests.

there’s no mistaking the beauty of majestic icescapes like this!❄️ operation icebridge, the largest airborne survey to map earth’s polar ice, captures unprecedented three-dimensional views of arctic and antarctic ice sheets, ice shelves and sea ice. many of the photographs from our lengthy missions feature the icy landscapes of greenland and antarctica, but the view during our shorter missions reveal some equally majestic landscapes, like this image of the wrangell mountains in eastern alaska. clouds like those pictured here were persistent throughout the icebridge mission, but the researchers still managed to collect data during 10 of 11 possible flight days. data collected during operation icebridge will help scientists better understand processes that connect the polar regions with the global climate system.

dynamic loops extend off the sun a distance ten times the diameter of earth in this extreme ultraviolet light view from our solar dynamics observatory seen may 30-june 1, 2018. when the magnetic field lines get themselves tangled up enough, they can erupt with a solar storm.
we use the observatory to understand the sun's influence on earth and near-earth space by studying the solar atmosphere in many wavelengths simultaneously. this allows us to better understand the solar variations that influence life on earth and humanity's technological systems by looking for solar wind, energetic particles, and variations in the solar irradiance that lead to better predictions of space weather events.

cue jaw-drop 😮 behold, our beautiful planet earth in all its natural splendor, captured from 250 miles above by astronaut ricky arnold (@astro_ricky) who is currently living and working on the international space station (@iss). he posted this stunning shot of the red sea to social media saying, “humankind’s most advanced technology serves as the foreground for a timeless land." as you read this, six humans are orbiting planet earth at 17,500mph in a football-field sized microgravity laboratory. during their time on the space station, they conduct important science and research that not only benefits life here on earth, but will eventually help us send humans deeper into the solar system than ever before.

out of a sea of silver sparkles from nearby stars, a ripple of bright blue gas threads through this galaxy like a misshapen lake. a keen eye can also spot a few other galaxies that, while masquerading as stars at first glance, reveal their true nature on closer inspection of this image from the hubble space telescope (@nasahubble). the central galaxy streaked with color was discovered by delisle stewart in 1900 and is located approximately 28 million light-years away. it contains an active galactic nucleus: an extremely luminous central region so alight with radiation that it can outshine the rest of the galaxy put together.
this galaxy has been imaged by hubble for several studies of nearby active galaxies. by using hubble to explore the small-scale structures of active galaxies in nearby galaxies, astronomers can observe the traces of collisions and mergers, central galactic bars, nuclear starbursts, jets or outflows, and other interactions between a galactic nucleus and its surrounding environment. images such as this can help astronomers understand more about the true nature of the galaxies we see throughout the cosmos.
