Like a witness to a violent death, NASA's Hubble Space Telescope recently gave astronomers an unprecedented, comprehensive view of the first moments of a star's cataclysmic demise.
Scientists thought Bennu's surface was like a sandy beach, abundant in fine sand and pebbles, which would have been perfect for collecting samples. But when NASA's OSIRIS-REx mission arrived at Bennu in late 2018, the mission saw a surface covered in boulders.
There are no known threats to Earth, but NASA asteroid expert Dr. Kelly Fast says it’s important to find the asteroids before they find us. That’s why NASA’s Planetary Defense Coordination Office keeps its eyes on the skies.
This November, we're launching the Double Asteroid Redirection Test, or... Read More
Instruments, like this flux tower, are used by scientists to verify the accuracy of the data available in OpenET, a powerful new web-based platform that puts Earth science data about water use by crops and other vegetation into the hands of farmers and water managers.
The surface of Venus is inhospitable for life: barren, dry, crushed under an atmosphere about 90 times the pressure of Earth’s and roasted by temperatures two times hotter than an oven. Was it always that way? Could Venus have been a habitable world with oceans? This is one of many mysteries... Read More
Lakes provide drinking water for people, habitat for plants and wildlife, and a place to fish, boat and swim. But the water can become harmful to humans, animals and the ecosystem when toxic algae called cyanobacteria reach abnormally high levels due to warm, nutrient-rich water conditions.
Our corner of the universe, the solar system, is nestled inside the Milky Way galaxy, home to more than 100 billion stars. The solar system is encased in a bubble called the heliosphere, which separates us from the vast galaxy beyond – and some of its harsh space radiation.
NASA has selected a new space telescope proposal that will study the recent history of star birth, star death, and the formation of chemical elements in the Milky Way.
Here are five facts to help you better understand Arctic sea ice.
Two microphones aboard the six-wheeled spacecraft add a new dimension to the way scientists and engineers explore the Red Planet.
NASA’s Perseverance rover captures a geologic feature with details that offer clues to the area’s mysterious past.
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.
