A large, gaseous planet orbits a red giant star that should have destroyed it. It's 530 light-years from Earth.

Study reveals how magma oceans may affect the evolution of hot exoplanets. Lava worlds, massive exoplanets home to sparkling skies and roiling volcanic seas called magma oceans, are distinctly unlike the planets in our solar system. To date, nearly 50% of all rocky exoplanets yet discovered ha

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

Planning is underway for NASA's Habitable Worlds Observatory In early August, scientists and engineers gathered in a small auditorium at Caltech to discuss how to build the first space telescope capable of detecting life on planets like Earth. The proposed mission concept, called the Habitable Worl

NASA's Small Bodies Assessment Group wants the agency to send spacecraft to visit the asteroid Apophis before it makes a close approach to Earth in 2029.

NASA's Lucy spacecraft provides its first glimpse of asteroid Dinkinesh. Over a span of two months, Lucy will get closer, testing its systems before a close flyby on November 1, 2023. The small dot moving against the background of stars is the first view from NASA’s Lucy spacecraft of the main be

Astronomers uncover details of a massive star, ASASSN-14li, devoured by a black hole, challenging previous theories and hinting at new methods for cosmic exploration.

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 warning comes as the U.S. space economy is predicted to reach $1 trillion by 2030.

This could explain how supermassive black holes grew to have masses billions of times that of the sun so quickly in the early universe.

How humanity responds to the first contact with intelligent alien life could determine the very fate of our species.

Armed with this promising new tool, a cutting-edge observatory in Chile will sweep the cosmos for all sorts of transient objects.

On July 26, NASA's OSIRIS-REx spacecraft fired its engines for about 63 seconds to slightly thrust itself onto a course closer to Earth.

"This result does not fit in with the currently accepted cosmological models, which include dark matter."

New research led by Newcastle University and published in the Monthly Notices of the Royal Astronomical Society has revealed that supermassive black holes obscured by dust are more likely to grow and release tremendous amounts of energy when they are inside galaxies that are expected to collide with a neighboring galaxy.
