A new NASA supercomputer simulation of the planet and debris disk around the nearby star Beta Pictoris reveals that the planet's motion drives spiral waves throughout the disk, a phenomenon that greatly increases collisions among the...

Since the early 1990's, astronomers have known that extrasolar planets, or "exoplanets," orbit stars light-years beyond our own solar system. Although most exoplanets are too distant to be directly imaged, detailed studies have been...

The exoplanet WASP-76 b, an ultra-hot gas giant, may be even hotter than scientists realized.

Thanks to the ESA’s Cheops space telescope, scientists can now see the strange features of exoplanet WASP-189b and its blue star <br/>

This image, taken with the Hubble Space Telescope, shows a distant galaxy located in the constellation Fornax. It is the largest and one of the most complete Einstein rings ever discovered.

A team of scientists has discovered an Earth-size exoplanet in the habitable or “Goldilocks” zone of its star while reviewing old data from the Kepler Space Telescope, according to a press release from NASA.

Astronomers have used many different methods to discover planets beyond the solar system, but the most successful by far is transit photometry, which measures changes in a star's brightness caused by a mini-eclipse. When a planet...

During its K2 campaign, NASA's Kepler spacecraft observed the eighth planet in our solar system, Neptune. Kepler detected small changes in Neptune's brightness caused by the planet's daily rotation, the movement of...

Scientists found a giant planet 325 light years away, but its very existence proves there’s something wrong with science.

NASA is celebrating the Hubble Space Telescope’s 32nd birthday with a stunning look at five galaxies, a close-knit collection called the Hickson Compact Group 40.

This amazing assembly includes a giant elliptical...

On a quest to find out if we are not alone in the universe, Ravi Kopparapu at NASA Goddard studies how we could use telescopes to detect signs of life beyond our solar system.

Astronomers have used new and archival datasets from NASA’s Hubble Space Telescope to uncover evidence of water vapor in the atmosphere of Jupiter’s moon Ganymede.

When a new NASA space telescope opens its eyes in the mid 2020s, it will peer at the universe through some of the most sophisticated sunglasses ever designed.



This multi-layered technology,...

Fast radio bursts, or FRBs, are extraordinary events that generate as much energy in a thousandth of a second as the Sun does in an entire year!



Astronomers using NASA’s Hubble Space Telescope have...

NASA's Transiting Exoplanet Survey Satellite (TESS) has discovered its first Earth-size planet in its star's habitable zone, the range of distances where conditions may be just right to allow the presence of...

An international team of astronomers exploring the disk of gas and dust the bright star Beta Pictoris have uncovered a compact cloud of...

NASA’s Transiting Exoplanet Survey Satellite (TESS) will find undiscovered worlds around bright nearby stars, providing targets where future studies will assess their capacity to harbor life. TESS is a NASA Astrophysics...

Researchers working with data from NASA’s Transiting Exoplanet Survey Satellite (TESS) have discovered the mission’s first circumbinary planet, a world orbiting two stars. The planet, called TOI 1338b, is around 6.9...

Scheduled to launch in the mid-2020s, the Nancy Grace Roman Space Telescope, formerly known as WFIRST, will function as Hubble’s wide-eyed cousin. While just as sensitive as Hubble's cameras, the Roman...

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...

An international team of astronomers using data from NASA's Hubble Space Telescope has detected significant changes in the atmosphere of a planet located beyond our solar system. The scientists conclude the atmospheric...

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...

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...
