The Second Servicing Mission, launched Feb. 11, 1997, greatly improved Hubble's productivity. The installation of new instruments extended Hubble's wavelength range into the near infrared for imaging and...

Astronomers using the Hubble Space Telescope have conducted the first spectroscopic survey of Earth-sized planets in the TRAPPIST-1 system's habitable zone. Hubble reveals that at least the inner five planets do not seem to...

For the past 31 years, the Hubble Space Telescope has continued its important mission of uncovering the mysteries of the universe. One of those mysteries that Hubble has helped us begin to understand is...

A spectacular head-on collision between two galaxies fueled an unusual triangular-shaped star-birthing frenzy, as captured in a new image from NASA’s Hubble Space Telescope.



The interacting galaxy duo is...

Scientists using NASA’s Hubble Space Telescope have found evidence that a planet orbiting a distant star that may have lost its atmosphere but gained a second one through volcanic activity.



The planet,...

With Jim Green today is the “man about Mars,” Bruce Jakosky from the University of Colorado. Bruce is the principal investigator of NASA's MAVEN mission. Joining them is Michael Meyer the lead Mars scientist at NASA Headquarters.

At NASA, we are driven by curiosity, and we know you are too! Join us as we hear from our previous episode experts about what they’re interested in and answer some questions from listeners like you. What are you still curious about?

Can planets exist in multi-star systems, and what would that look like from their perspective? Thanks to Blinkist for sponsoring today's video.

This animated video is all about earth's only natural satellite - The Moon. Students will love this engaging and interactive video.

On March 21, 2022, the number of known exoplanets passed 5,000 according to the NASA Exoplanet Archive. This animation and sonification tracks humanity's discovery of the planets beyond our solar system over time. Turning NASA data...

On July 4, NASA’s Transiting Exoplanet Survey Satellite (TESS) completed its primary mission, a two-year-long survey that imaged about 75% of the starry sky. In capturing this giant mosaic, TESS has found 66...

In celebration of the 31st anniversary of the launching of NASA’s Hubble Space Telescope on April 24, 1990, astronomers aimed the renowned observatory at a brilliant “celebrity star,” one of the brightest...

This video provides a description of the planet Mercury, the closest planet to the sun in our solar system. It highlights key facts about Mercury, such as its diameter, mass, lack of moons, and orbit period. The video also mentions the...

In this episode of Gravity Assist, Jim Green talks with New Horizons Principal Investigator Alan Stern of the Southwest Research Institute about what the July 2015 flyby of Pluto revealed about this mysterious and diverse world.

Learn more about the Voyager space probes in this video with Dr. Michelle Thaller of NASA.

Humans have always looked up at the sky. They used astronomy to track time, orient their cities, decide when to plant their crops, and even based their religious practices on their celestial world. But there was much more to learn.<br/>

NASA satellites use very sensitive devices called magnetometers to measure the magnetic fields of planets. Like very sensitive compasses, these devices can measure both direction and strength of planetary magnetic fields. <b<b<br/>r/>r/>

The Hubble and Kepler space telescopes found evidence for what could be a giant moon accompanying a gas-giant planet that orbits the star Kepler-1625, located 8,000 light-years away in the constellation Cygnus. The moon may...

Dr. Amy Simon has always been fascinated with space. From a young age she dreamed of lifting off in the space shuttle, just like her hero, astronaut Sally Ride. Over the years her interest in space remained, and...

Discover never-before-seen footage of our planet, recorded with cameras from the International Space Station as it orbits Earth. From this unique and privileged vantage point, this short illustrates the beauty of the Nordic lights from...

NASA officially is beginning work on an astrophysics mission designed to help unlock the secrets of the universe -- the Wide Field Infrared Survey Telescope (WFIRST).



With a view 100 times bigger than that of...

NASA scientists are seeking a strange breed of northern lights in the Arctic. When these auroras shine, Earth’s atmosphere leaks into space.



In the tiny Arctic town of Ny-Ålesund,...

Shortly after the Hubble Space Telescope was deployed in 1990, the observatory's primary mirror was discovered to have an aberration that affected the clarity of the telescope's early images....

How do we spot something as tiny and faint as a planet trillions of miles away? The trick is to look at the star! So far, most of the exoplanets – worlds beyond our solar system – we’ve found were detected by looking for tiny...
