In a solar system called TRAPPIST-1, 40 light years from the sun, seven Earth-sized planets revolve around a cold star.

Astronomers using data from NASA’s James Webb Space Telescope have identified carbon dioxide in a specific region on the icy surface of Jupiters moon Europa.

The German project aims to explore beneath Earthly ice as a test for space exploration.

A much anticipated NASA report on UFOs calls for better tracking and scientific understanding of unexplained phenomena that captivate the public and have raised concerns about military security.

Triton orbits to the beat of its own drum.

A new investigation by an international team of astronomers using data from the NASA/ESA/CSA James Webb Space Telescope into K2-18 b, an exoplanet 8.6 times as massive as Earth, has revealed the presence of carbon-bearing molecules including methane and carbon dioxide. The discovery adds to recent studies suggesting that K2-18 b...

Scientists have discovered six new exoplanets, taking the total to 5,502. With advancements in technology, the field of exoplanet research has grown exponentially since the first discovery in 1992, and upcoming instruments promise even deeper insights.

A pair of astrophysicists, one with Kindai University, the other the National Astronomical Observatory of Japan, both in Japan, have found possible evidence of an Earth-like planet residing in the Kuiper Belt. In their paper published in The Astronomical Journal, Patryk Sofia Lykawka and Takashi Ito describe properties of the...

New Giant Planet Is Evidence of Possible Planetary Collisions A Neptune-sized planet denser than steel has been discovered by an international team of astronomers, who believe its composition could be the result of a giant planetary clash. TOI-1853b's mass is almost twice that of any other similar

Researchers from the University of Arizona have found a youthful exoplanet that may shed light on this phenomenon and offer insights into how planets form. Illustrations of the Milky Way exhibit a spiraling design of "arms" loaded with stars that radiate from the center. Comparable formations are s

There are more than 5,000 confirmed exoplanets in our galaxy. That number is going to rise significantly in the next decade. The Transiting Exoplanet Survey Satellite (TESS) has already cataloged more than 4,000 candidate exoplanets, and the PLAnetary Transits and Oscillations of stars (PLATO) is scheduled to launch in 2026.

The largest storm in the solar system, a 10,000-mile-wide anticyclone called the Great Red Spot, has decorated Jupiter's surface for hundreds of years.

'We now have for the first time vestiges of times that could have been conducive to the origin of life.'

Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered a new giant exoplanet transiting a nearby M-dwarf star. The newfound alien world, designated TOI-4860 b, is comparable in size and mass to Saturn. The finding is reported in a paper published August 2 on the pre-print...

A Southwest Research Institute-led team has modeled the early impact history of Venus to explain how Earth's sister planet has maintained a youthful surface despite lacking plate tectonics. The team compared the early collision histories of the two bodies and determined that Venus likely experienced higher-speed, higher-energy...
