For the past 30 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 understand are exoplanets. Video credit: NASA's Goddard...

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 contain...

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 into...

Dubbed Ariel, the spacecraft is expected to launch in 2029 on ESA’s new Ariane 6 rocket.

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 be as big as...

Parked in space a million miles from Earth, the Earth Polychromatic Imaging Camera (EPIC) onboard the Deep Space Climate Observatory (DSCOVR) captures glimmers of reflected sunlight, evidence of ice crystals in the atmosphere. Credit:...

Space researchers have proposed building a network of radio antennas on the far side of the moon.

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’s Hubble Space...

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, where polar bears outnumber people, winter means three...

This video is answering the question of what is an exoplanet.

In a generic brick building on the northwestern edge of NASA’s Goddard Space Flight Center campus in Greenbelt, Maryland, thousands of computers packed in racks the size of vending machines hum in a deafening chorus of data crunching....

This time-lapse video reveals NASA’s James Webb Space Telescope is now a fully assembled observatory, and is accomplishing large-scale deployments and movements that it will perform while in space. Ensuring mission success for an...

NASA’s Kepler Confirms 100+ Exoplanets During Its K2 Mission: NASA in Silicon Valley Podcast

By studying this mysterious planet, scientists could learn a great deal more about exoplanets, as well as the past, present, and possible future of our own. This video unveils this world and calls on current and future scientists to...

The inspiring 30-year tale of the discovery of worlds outside our solar system, told in a medley of songs from Disney's "Aladdin"

NASA's Transiting Exoplanet Survey Satellite (TESS) has discovered 21 planets outside our solar system and captured data on other interesting events occurring in the southern sky during its first year of science. TESS has now turned its...

NASA's James Webb Space Telescope has successfully passed another series of critical testing milestones on its march to the launch pad. In recent acoustic and sine vibration tests, technicians and engineers exposed Webb’s spacecraft...

Using powerful telescopes, in space and on the ground, astronomers have now confirmed more than 5,000 exoplanets – planets beyond our solar system. But it’s just a fraction of the likely hundreds of billions of such planets in our Milky...

Life as we know it requires three ingredients: energy, organic molecules, and liquid water. Astrobiology, our search for life beyond Earth, is a search for planets, dwarf planets, and moons that harbor substantial liquid water. We call...

Scheduled to launch in the mid-2020s, the Wide Field Infrared Survey Telescope (WFIRST) will function as Hubble’s wide-eyed cousin. While just as sensitive as Hubble's cameras, WFIRST's 300-megapixel Wide Field Instrument will image a...

Astrum investigates some examples of the longest and shortest years that we know of. The differences are mind-boggling!

Just as our own sun has many planets, other stars also have planets of their own. These are called exoplanets. The first of these was discovered in the 1990s, and since then, thousands of others have been found, thanks largely to the...

We've briefly discussed exoplanets and some methods that we can use to detect them, but we haven't yet looked at any specific ones. You may have heard of the TRAPPIST-1 system that was discovered recently, and for good reason, it's a...
