Like all the planets, asteroids exist in the heliosphere, the vast bubble of space defined by the reaches of our Sun’s wind. Directly and indirectly, the Sun affects many aspects of existence within this pocket of the universe. Here are a few of the ways the Sun influences asteroids like the... Read More
NGC 4666, a majestic spiral galaxy, takes center stage in this image from the NASA/ESA Hubble Space Telescope.
NASA’s Hubble Space Telescope observations of Jupiter’s icy moon Europa have revealed the presence of persistent water vapor – but, mysteriously, only in one hemisphere.
Did Mars ever look like Earth? We think it did! Ancient Mars may have been wetter and warmer — similar to our home planet. So what happened? Scientists like Dr. Becky McCauley Rench are trying to find out. Keep up with our Martian exploration efforts: www.nasa.gov/Mars.
As satellites collect larger and larger amounts of data, engineers and researchers are implementing solutions to manage these huge increases.
The public is invited to participate in several of NASA’s virtual activities in celebration of International Observe the Moon Night on Saturday, Oct. 16.
NASA, along with the European Space Agency, is developing a campaign to return the Martian samples to Earth.
As the ice-and-snow rubble known as mélange melts in Antarctica’s ice shelves, rifts can grow and icebergs break off even in the brutal cold of winter.
Dynamic Radioisotope Power Systems may enable lunar science payloads to survive and thrive during the harsh lunar night.
This NASA/ESA Hubble Space Telescope image features two interacting galaxies that are so intertwined, they have a collective name – Arp 91.
The U.S. Forest Service now has a powerful way to view near-real time fire detection from NASA satellite data that they can include in their hourly air quality forecasts.
NASA's Hubble Space Telescope uncovered what appears to be a pair of identical objects that look so weird it took astronomers several years to determine what they are. Turns out they are stretched images of a gravitationally lensed distant galaxy, located more than 11 billion light-years away... Read More
What are some skywatching highlights in October 2021? See several groupings of the Moon, planets, and stars at sunrise and sunset. Then get to know two bright stars that are part of a special group: along with a handful of others, they take turns with Polaris as North Star over thousands of years.... Read More
At the Space Laser Assembly Cleanroom at NASA’s Goddard Space Flight Center, the Laser and Electro-Optics Branch is building lasers for NASA’s Dragonfly mission to Titan and the European Space Agency’s Laser Interferometer Space Antenna, which will measure waves in space-time caused by massive...
