Teams across the country have been competing for years to be the first to engineer functional human tissue in a lab. Now, scientists have accomplished this medical feat by creating thick vascularized human organ tissue, which could have profound implications both on Earth and off. 🎥Credits:NASA

On April 19, the Ingenuity Mars helicopter became the first spacecraft to achieve powered, controlled flight on another world. This historic flight on Mars has implications for how we will explore other worlds. Join experts from the Ingenuity Mars Helicopter team and upcoming Dragonfly mission to learn about the future of extraterrestrial flight. Date Created:2021-05-04 🎥Credits:NASA

The Fermi Gamma-ray Space Telescope recently produced a map of the night sky. Out of 1873 new sources, nearly 600 were complete mysteries. In this week's ScienceCast, researchers speculate on the nature of the mystery objects.

Venus, our planetary neighbor, is a hot, hellish unforgiving world. Its toxic atmosphere and sweltering surface make it a challenging place to study, and it’s been over 3 decades since NASA visited Earth’s evil twin...until now! NASA is sending two bold new missions to study this inferno-like world: DAVINCI+ and VERITAS. Join Venus mission experts on this episode #NASAScience Live.

NASA's MESSENGER probe has discovered a surprise on Mercury: Something is digging "hollows" in the surface of the innermost planet.

This year at NASA, Earth Day is about connections—to our planet and to each other. Our planet is home to over 7 billion people of diverse backgrounds and experiences, but we are all #ConnectedByEarth. Join NASA climate experts to learn about the connections between human activity and climate change. Date Created:2021-04-22 🎥Credits:NASA

Forecasters say Earth is heading for a stream of dust from Comet 21P/Giacobini-Zinner. A close encounter with the comet's fragile debris could spark a meteor outburst over parts of our planet on October 8th.

Is there life beyond Earth? NASA has been sending spacecraft to the far reaches of our solar system in search of an answer. But extreme forms of life on our own planet might reveal secrets of how life could form beyond Earth. Meet two NASA women who have ventured on remote expeditions and traversed Earth’s most extreme landscapes in the name of science and astrobiology.

NASA's newest rover Curiosity is getting ready to leave Earth. It's destination: Gale crater on Mars. Today's story explains the attraction of this Martian crater with a strangely-sculpted mountain the middle.

Behind every NASA success story are the people who make the impossible, possible. Join us as we celebrate Black History Month and the contributions of African American trailblazers and those following in their footsteps as they help NASA reach new heights for the benefit of all humankind. 🎥Credits:NASA

Researchers have just discovered that solar flares have been keeping a secret--and it's a big one.

A new chapter of Mars exploration officially began! On February 18, 2021, NASA’s Perseverance rover successfully landed on Mars. What happened next? The rover began preparing to explore its new Martian home, searching for signs of ancient life and collecting samples to be returned by a future mission. 🎥Credits:NASA

Did our planet once have two moons? Some researchers say so. Moreover, the missing satellite might still be up there--splattered across the far side of the Moon. NASA's GRAIL mission could help confirm or refute the "two moon" hypothesis.

Did you notice two bright objects in the sky getting closer together each night? That was Jupiter and Saturn doing a planetary dance that culminated in the Great Conjunction on Dec. 21. 2020. On that day, Jupiter and Saturn appeared right next to each other in the sky—the closest they had been in nearly 400 years!

Stars as cold as the human body? Believe it. A NASA spacecraft has discovered a half-dozen "Y Dwarfs" with atmospheric temperatures as low as 80 F.

Pluto is a world of mystery waiting to be visited for the 1st time. NASA's New Horizons probe is racing across the solar system for a close encounter that could alter what researchers "know" about Pluto and other small worlds.

No matter who you are or where you are, YOU can participate in the science done at NASA and make new discoveries alongside NASA scientists. Watch NASA Science to hear from people around the globe about how they’re doing NASA science and learn how you too can get involved with NASA’s citizen science projects.

On August 13th, space station astronaut Ron Garan photographed a centimeter-sized chunk of comet debris disintegrating in Earth's atmosphere. His rare photo of a meteor from Earth orbit is a must-see.

Sea levels across the globe are rising as a result of a changing climate — and the rate at which they are rising is accelerating. Watch NASA Science Live to meet NASA researchers studying these changes, and learn how the next mission launching to space will continue the nearly 30-year record of monitoring Earth’s ocean from space.

The same kind of oxygen humans breath on Earth has been found in deep space. It's a breath of fresh air for astronomers who have been searching for cosmic "O2" until now without success. 🎥Credits:NASA

Asteroids are prehistoric treasures that hold the lost tales about the origin of our solar system. We are slowly starting to unfold this story and NASA’s Lucy mission will launch in about a year to venture on a 12-year tour studying diverse primordial worlds. 🎥Credits:NASA

NASA's Dawn spacecraft doesn't do things like other missions. In July 2011, it slipped into orbit around asteroid Vesta using a smooth move that made mission planners want to get up and dance. 🎥Credits:NASA

NASA has touched the surface of asteroid Bennu to collect the agency’s first ever asteroid sample, which will one day shed new insights on the history of our solar system… so what’s next? 🎥Credits:NASA

For four long centuries, the gas giant's vast interior remained hidden from view. NASA's Juno probe, launched on August 5th, 2011, aimed to change all that. 🎥Credits:NASA
