Astronomers and visualization specialists from NASA's Universe of Learning program have combined visible and infrared vision of the Hubble and Spitzer space telescopes to create an unprecedented, three-dimensional, fly-through view of the picturesque Orion Nebula, a nearby star-forming region.


Researchers using NASA's Mars Reconnaissance Orbiter (MRO) have found eight sites where thick deposits of ice beneath Mars' surface are exposed in faces of eroding slopes.


The SETI Institute and the Mars Institute announced today the discovery of small pits in a large crater near the North Pole of the Moon, which may be entrances to an underground network of lava tubes.


The Expedition 54 crew aboard the International Space Station is training for this weekend's departure of the SpaceX Dragon commercial cargo craft. The crew is also exploring regenerative life support systems and how microgravity affects breathing.


New detections of radio waves from a repeating fast radio burst have revealed an astonishingly potent magnetic field in the source's environment, indicating that it is situated near a massive black hole or within a nebula of unprecedented power.


For the first time since the twin Voyager spacecraft missions in 1979, scientists have produced far-infrared maps of Jupiter using NASA's Stratospheric Observatory for Infrared Astronomy, SOFIA.


NASA rockets launched during the Alaskan winter typically explore the interaction of solar winds with Earth's atmosphere and the resulting auroras that dance across the night sky.


NASA's Tracking and Data Relay Satellites (TDRS) don't just enable data from spacecraft to reach Earth - they provide internet and even telemedicine to researchers at the South Pole.


Scientists have solved a cosmic mystery by finding evidence that supermassive black holes prevent stars forming in some smaller galaxies.


In 2013, researchers announced that a pebble found in south-west Egypt, was definitely not from Earth.


Today - Human Research Program (HRP) Collections (Biochemical Profile, Repository): Over the weekend, a 52S subject completed his Flight Day (FD) 120 urine sample collections to support the Biochemical Profile and Repository experiments. The samples were placed in the Minus Eighty Degree Celsius Laboratory Freezer for ISS (MELFI).


The SCHOTT melting team has started casting the first mirror segments that will make up the 39-meter primary mirror (M-1) of the European Large Telescope (ELT).


Using the now-complete Cassini data set, Cornell astronomers have created a new global topographic map of Saturn's moon Titan that has opened new windows into understanding its liquid flows and terrain.


Today - Amyloid: Today the crew retrieved the final set of Amyloid samples from the measurement experiment unit on the Cell Biology Experiment Facility (CBEF) and placed them in a Minus Eighty Degree Celsius Laboratory Freezer for ISS (MELFI) where they will remain until they are returned on SpaceX-13.


Saturn's rings, made of countless icy particles, form a translucent veil in this view from NASA's Cassini spacecraft.


NASA's Juno spacecraft was a little more than one Earth diameter from Jupiter when it captured this mind-bending, color-enhanced view of the planet's tumultuous atmosphere.


SpaceX launched the classified payload for customer Northrup Grumman Sunday evening at 8:00 p.m. EST from Space Launch Complex 40 (SLC-40) at Cape Canaveral Air Force Station, Florida.


This image, captured by the NASA/ESA Hubble Space Telescope's Wide Field Camera 3 (WFC3), shows a galaxy named UGC 6093.


Robotics controllers have completed the science cargo transfers from the rear of the SpaceX Dragon cargo ship, also known as its trunk. Dragon is due to depart the International Space Station Jan. 13 and return to Earth.


This photograph taken by Expedition 54 crew members aboard the International Space Station reveals striking climate differences of Nepal and the Himalayan mountain range, including Mount Everest (left) and the Tibetan highlands of western China (right).


For the first time, scientists have shown through direct observations of the ozone hole by a satellite instrument, built by NASA's Jet Propulsion Laboratory in Pasadena, California, that levels of ozone-destroying chlorine are declining, resulting in less ozone depletion.


Brown dwarfs muddy a clear distinction between stars and planets, throwing established understanding of those bodies, and theories of their formation, into question.


The Expedition 54 crew is starting the New Year studying how humans adapt to living in space for months and years at a time. NASA and its international partners are also learning how to support crews on longer missions with less help from the ground.


Before we can run or jump, we walk. Before sending humans to Mars, NASA must understand how the human body is affected by living and working in space.


Just like the Sun is moving in our galaxy, the Milky Way, all the stars in galaxies are moving, but with very different orbits: some of the stars have strong rotations, while others may be moving randomly with no clear rotation.


Today - Amyloid: Over the weekend, the crew retrieved the third set of Amyloid samples from the measurement experiment unit on the Cell Biology Experiment Facility (CBEF) and placed them in a Minus Eighty Degree Celsius Laboratory Freezer for ISS (MELFI).


Today - Synthetic Bone BioCell Operations: The crew completed microscopy operations for Synthetic Bone and then took a sample from each well on the Synthetic Bone Multiwell BioCell and exchanged the fluids with media in each well.
