As Oumuamua leaves our solar system, we explore the reasons for continuing the chase.

NASA's Juno probe is coming to the end of a fantastic mission, but it's still got some tricks up its sleeve yet.

Why shouldn't we throw garbage into the sun? Find out in this return of our series 'Astrum Answers'.

NASA is about to launch a new spacecraft to look at the universe in X-ray light. The Imaging X-Ray Polarimetry Explorer, IXPE, will look at extreme objects such as black holes, neutron stars, and supernovae, asking fundamental questions...

The laws of physics get very, very weird in the realm of particles too small for the eye to see. Aboard the International Space Station, an experiment called the Cold Atom Laboratory (CAL) is exploring how the universe works .

From lunar samples brought back in the Apollo program, scientists have figured out that the Moon once had a shield around it called a magnetosphere, just like the Earth has today. As NASA prepares to send humans to the Moon, and...

Recent maps of the Moon's gravity have taught us a lot about its overall shape, and have been invaluable for lunar exploration. Maria Zuber, principal investigator of the Gravity Recovery and Interior Laboratory (GRAIL) mission, reflects...

Is there life beyond Earth? How did life get started on Earth anyway? This season of NASA’s Gravity Assist podcast is about the origins of life on Earth and the search for life elsewhere.[scald=338003:full_width][scald=338003:full_width]

As large as 1,000 Earths, Jupiter is the heavy hitter of the solar system. Even its Great Red Spot is larger than Earth, yet it’s shrinking! In this episode of Gravity Assist, Planetary Science Director Jim Green talks with Jared Espley...

Learn about how the Moon formed in this conversation with Robin Canup of the Southwest Research Institute.

Why don’t we go live on Saturn’s moon Titan? What would it mean if we found life elsewhere? How did life get its start on Earth? NASA’s chief scientist Jim Green and astrobiologist Lindsay Hays discuss these and other audience questions...

The James Webb Space Telescope, which launched Dec. 25, will allow us to see the farthest galaxies and better understand the origins of the Milky Way. Aaron Yung at NASA’s Goddard Space Flight Center is preparing for these historic...

To study the history of life on Earth and look for it beyond our planet, scientists in the field of astrobiology look for signs called “biosignatures.” NASA Goddard researcher Heather Graham discusses some of the oldest evidence of life...

Vladimir Airapetian, scientist at NASA’s Goddard Space Flight Center, explains what researchers hope to find as they gaze beyond our solar system.

Listen to Chief Scientist Jim Green and a co-investigator on the Kepler and TESS missions, Jon Jenkins, discuss exoplanet-hunting and all the amazing discoveries Kepler has made.

While more research is needed, Smith and others are fascinated by the possibility that airborne microbes could also be found elsewhere in the solar system, and beyond.

Laurie Barge, an astrobiologist at NASA’s Jet Propulsion Laboratory, studies how plant-looking mineral structures called chimneys grow from chemicals found at the deepest depths of the ocean. In her lab she has glass vials and bulbs full...

From diving in Antarctica’s ice-covered lakes to exploring Mexico’s Cave of the Crystals, NASA astrobiologist Chris McKay has been searching for life in a wide variety of extreme environments on Earth.

What’s the difference between climate and weather? How does NASA monitor changing sea levels, melting glaciers, and other effects of climate change? Gavin Schmidt, NASA’s acting senior climate advisor, explains how rising temperatures...

Go behind the scenes at NASA with Chief Scientist Jim Green in the Gravity Assist podcast.

Learn how Moon rocks can reveal all kinds of information about our nearest neighbor, as NASA prepares to send astronauts to the Moon and on to Mars.

When Earth was just a baby, meteors and asteroids rained down, delivering all sorts of chemicals to our developing planet. These small objects could have delivered the chemicals needed to spark life on Earth for the first time.

NASA is sending two missions to Venus this decade and participating in a European Space Agency mission there, too. Lori Glaze, director of planetary science at NASA, discusses these missions and why she’s so excited about what we’re...

Climate change is one of the most important issues facing our planet, and NASA has lots of space missions and programs in the works to monitor and understand its drivers and effects. Kate Calvin, NASA’s new chief scientist, is also the...
