With the discovery of seven earth-sized planets around the TRAPPIST-1 star 40 light years away, astronomers are looking to the upcoming James Webb Space Telescope to help us find out if any of these planets could possibly support life.
Scientists have proven that the warning signs of one type of space weather event can be detected up to 17 minutes before it arrives at Earth -- critical time that could help protect astronauts in space.
Two separate investigations determine that microorganisms can survive on the surface of Mars, and deep in its subsurface.
The first images from the Solar Ultraviolet Imager or SUVI instrument aboard NOAA's GOES-16 satellite have been successful, capturing a large coronal hole on Jan. 29, 2017.
The events surrounding the Big Bang were so cataclysmic that they left an indelible imprint on the fabric of the cosmos. We can detect these scars today by observing the oldest light in the universe.
NASA is developing a new family of flexible heat-shield systems with a woven carbon-fiber base material, and is using X-rays to test the designs.
A trip past the sun may have selectively altered the production of one form of water in a comet -- an effect not seen by astronomers before, a new study suggests.
Mammalian cells fully adapt to zero gravity in less than a minute. Real-time readings on the International Space Station (ISS) reveal that cells compensate ultra-rapidly for changes in gravitational conditions, an international team of scientists has found.
As NASA prepares for its journey to Mars, one researcher is investigating why so many astronauts suffer from poorer vision after they return to Earth.
Hunting for habitable exoplanets now may be easier: astronomers report that hydrogen pouring from volcanic sources on planets throughout the universe could improve the chances of locating life in the cosmos.
Evidence of planetary debris surrounding a double sun, 'Tatooine-like' system has been found for the first time, report investigators.
Three decades ago, a massive stellar explosion sent shockwaves not only through space but also through the astronomical community. SN 1987A was the closest observed supernova to Earth since the invention of the telescope and has become by far the best studied of all time, revolutionizing our understanding of the explosive death of massive stars.
The New Horizons flyby of Pluto and its satellites returned a scientific treasure trove of information about these distant and surprisingly complex worlds, showing a vast nitrogen glacier as well as ice mountains, canyons, cliffs, craters and more. Now the categories for official names have been approved and the name proposals can be submitted by the New Horizons team.
Bubbles acting like parachutes are deployed by some cosmic dust particles on their entry into Earth’s atmosphere, preventing them from burning up.
Surprising images from the Rosetta spacecraft show the presence of dune-like patterns on the surface of comet Chury. Researchers have studied the available images and modeled the outgassing of vapor to try to explain the phenomenon. They show that the strong pressure difference between the sunlit side of the comet and that in shadow generates winds able to transport grains and form dunes.
New planetary formation models indicate that there may be an undiscovered population of gas giant planets orbiting around Sun-like stars at distances similar to those of Jupiter and Saturn.
The dynamical properties of these asteroids, observed spectroscopiccally for the first time using the Gran Telescopio CANARIAS, suggest a possible common origin and give a clue to the existence of a planet beyond Pluto, the so-called 'Planet Nine.'
New research reveals that the Earth's unique iron composition isn't linked to the formation of the planet's core, calling into question a prevailing theory about the events that shaped our planet during its earliest years.
Sound travels more slowly than light. Then why do sounds of meteors entering Earth's atmosphere precede or accompany the sight of them? Researchers believe they have an answer.
New work shows that interactions between iron and nickel under the extreme pressures and temperatures similar to a planetary interior can help scientists understand the period in our Solar System's youth when planets were forming and their cores were created.
