Remnants of water once found on the surface of Mars may be hidden in a handful of small lakes below the Red Planet's south pole, and more could exist, according to new research.
What might Earth be like crowned with rings? Space and science- fiction illustrator Ron Miller created extraordinary images of how the sky might look if Earth possessed such rings.
Unusual flashes of gamma rays could reveal that what appear to be giant black holes are actually huge wormholes, a new study finds.
Astronomers have discovered a new type of alien world — the first known "ultra-hot Neptune," a giant planet that orbits its star 60 times closer than Earth does the sun, a new study finds.
Shiny boulders on one of the darkest asteroids in the solar system may shed light on the cataclysmic impacts behind that space rock's origins, a new study finds.
A team of scientists now suggests black holes could reach what they call "stupendously large" sizes, each harboring the mass of 100 billion suns or more.
The mystery of how giant cyclones stay together in geometric patterns around the poles of Jupiter may now be solved, but new questions have emerged as to how these clusters formed in the first place.
Astronauts lose bone and muscle mass on long-duration missions, but a new treatment administered to mice in space could prevent that from happening, a new study finds.
In the depths of Venus' hellish atmosphere, a layer of mysterious haze could be home to life, a new study finds.
Spacecraft made of carbon-foam bubbles could zoom from Earth to Alpha Centauri in 185 years, driven solely by the power of the sun, a new study finds.
Astronomers might detect black holes falling into wormholes via ripples in space and time called gravitational waves, a new study finds.
Scientists may one day detect alien planets outside the Milky Way using the ripples in space and time known as gravitational waves, a new study finds.
Scientists may one day be able to predict dangerous solar flares just one day in advance using a new solar outburst model, a new study finds.
An asteroid shower thought to have struck the moon and Earth 800 million years ago may have helped trigger Earth's greatest ice ages, a new study finds.
A strange white dwarf star hurtling through the Milky Way may be the survivor of a "partial supernova," a new study finds.
Earth's newborn moon may have possessed an ocean of magma for 200 million years, much longer than scientists thought, a new study finds.
The brightest red dwarf star in the sky may be the best chance astronomers have yet to analyze the atmospheres of alien worlds — and perhaps detect whether those worlds have life, a new study finds.
Though Pluto is now famously frigid, it may have started off as a hot world that formed rapidly and violently, a new study finds.
Mysterious pulses of radio waves from deep space can fire in regular patterns, a discovery that might help shed light on the cause of these puzzling outbursts, a new study finds.
Scientists have generated an exotic form of matter in the unique microgravity environment aboard the International Space Station and are using it to explore the quantum world, a new study finds.
The mystery behind why the atmosphere of Venus spins much faster than the planet's surface may finally be solved, a new study finds.
A distant world about 40 times more massive than Earth may be the remnant core of a giant planet, or a giant planet in the making whose growth stalled, a new study reports.
An exoplanet may be shaped like an American football due to the mighty gravitational forces it experiences close to its star, a new study finds.
A cannonball that a Japanese spacecraft fired at an asteroid is shedding light on the most common type of asteroid in the solar system, a new study reports.
