This Copernicus Sentinel-1 image takes us just south of the US border, to the region of Baja California in northwest Mexico. Its capital city, Mexicali, is visible top left of the image.


Scientists have discovered that a mysterious pressure dubbed "dark energy" makes up about 68% of the total energy content of the cosmos, but so far we don't know much more about it.


Wherever fires are burning around the world NASA-NOAA's Suomi NPP satellite's Ozone Mapping and Profiler Suite (OMPS) can track the smoke and aerosols.


This image, taken with the NASA/ESA Hubble Space Telescope, focuses on an object named UGC 695, which is located 30 million light-years away within the constellation Cetus (the Sea Monster), also known as the Whale.


Anyone who has ever peered at Saturn through a small telescope is immediately enticed by its elegant rings, which make the far-flung planet one of the most exotic-looking, opulent worlds in the solar system.


Engineers took NASA's Mars 2020 for a spin on Aug. 29, 2019. The 2,300-pound (1,040-kilogram) Martian vehicle was rotated clockwise and counterclockwise at about 1 revolution per minute on what is called a spin table in the clean room of the Spacecraft Assembly Facility at NASA's Jet Propulsion Laboratory in Pasadena, California.


An international team of astronomers has discovered one of the largest features ever observed in the center of the Milky Way - a pair of enormous radio-emitting bubbles that tower hundreds of light-years above and below the central region of our galaxy.


A newly discovered comet has excited the astronomical community this week because it appears to have originated from outside the solar system.


With data from the NASA/ESA Hubble Space Telescope, water vapour has been detected in the atmosphere of a super-Earth within the habitable zone.


Hot and dry. These are the watchwords for large fires. While every fire needs a spark to ignite and fuel to burn, it's the hot and dry conditions in the atmosphere that determine the likelihood of a fire starting, its intensity and the speed at which it spreads.


Every spring the sun shines on the side of the stack of layers at the North Pole of Mars known as the north polar layered deposits. The warmth destabilizes the ice and blocks break loose.


Almost all the planets of our solar system have moons. Each planetary system has however unique characteristics.


Rosetta observations of 67P/Churyumov-Gerasimenko (67P) reveal that most changes occur in the fallback-generated smooth terrains, vast deposits of granular material blanketing the comet's northern hemisphere.


Just as people of the same age can vary greatly in appearance and shape, so do collections of stars or stellar aggregates.


The final chapter of the historic detection of the powerful merger of two neutron stars in 2017 officially has been written.


Using radar data from NASA's Cassini spacecraft, recently published research presents a new scenario to explain why some methane-filled lakes on Saturn's moon Titan are surrounded by steep rims that reach hundreds of feet high.


The wildfires that have been devastating the Amazon rainforest have been international headline news over the last weeks.


While flying about 260 miles above the border between northeastern China and southeastern Russia, an uncrewed Russian Soyuz spacecraft undocked and departed from the International Space Station at 2:14 p.m. EDT.


On Sept. 4, 2019, a loose chain of tropical cyclones lined up across the Western Hemisphere.


Astronomers have discovered a planet three times the mass of Jupiter that travels on a long, egg-shaped path around its star.


A key tracer used to estimate how much atmosphere Mars lost can change depending on the time of day and the surface temperature on the Red Planet, according to new observations by NASA-funded scientists.


Located in the northern constellation of Ursa Major, which also includes the Big Dipper, nearby galaxy Messier 81 is easily visible through binoculars or a small telescope. M81 is located at a distance of 12 million light-years.


As cosmonaut Oleg Skripochka, NASA astronaut Jessica Meir and spaceflight participant Hazzaa Ali Almansoori ready for their Sept. 25 launch aboard a Soyuz MS-15 spacecraft, tomorrow they will pause in their mission preparations for the ceremonial laying of the flowers at the Kremlin Wall.


Expedition 60 flight engineer Christina Koch of NASA captured this image of Hurricane Dorian from the International Space Station on Sept. 2, 2019 as the storm churned over the northwestern Bahamas.


A new view of Hurricane Dorian shows the layers of the storm, as seen by an experimental NASA weather satellite that's the size of a cereal box.


While many NASA missions are tracking Hurricane Dorian as the storm makes its way toward the United States, some researchers are looking at what Dorian has already left behind.


Pops of bright blue and green in this image of the Fireworks galaxy (NGC 6946) show the locations of extremely bright sources of X-ray light captured by NASA's NuSTAR space observatory.


After a quiet, off-duty day for the crew of Expedition 60 on Labor Day, operations supporting science for long-duration human space exploration and upcoming spaceship movements ramped up on the International Space Station.


Astronaut Nick Hague, aboard the International Space Station, posted this photograph of Hurricane Dorian to Twitter on Sept. 2, 2019. He added, "You can feel the power of the storm when you stare into its eye from above. Stay safe everyone!" Larger image


NASA's IMERG storm-total rain accumulation over parts of Grand Bahama and Abaco islands have exceeded 24 inches according to NASA satellite-based estimates.


This Copernicus Sentinel-3 image features Hurricane Dorian as it pummels the Bahamas on 2 September 2019 at 15:16 GMT (11:16 EDT).


NASA has selected three proposals for concept studies of missions that could help us better understand the dynamic space weather system driven by the Sun that manifests near Earth.


Human research kept the Expedition 60 crew busy today helping NASA and its partners understand how to keep astronauts healthy on long-term space missions.
