NASA’s Perseverance Mars rover sealed the tube containing its 20th rock core sample on June 23 (the 832nd Martian day, or sol, of the mission). »
Astronomers using data from NASA’s Chandra X-ray Observatory and other telescopes have identified a new threat to life on planets like Earth. »
An Indian rocket has been launched into space to land a robotic rover on an unexplored part of the Moon. »
Researchers have spotted a planet beyond our solar system, that orbits a sun-like star every 19 hours and appears to be wrapped in metallic clouds made of titanium and silicates that reflect most incoming light back into space. »
Scientists have found evidence of a universal background of gravitational waves, or ripples in the fabric of space-time. »
A team of international scientists has used NASA’s James Webb Space Telescope to detect a new carbon compound in space for the first time. »
An international team of researchers has used NASA’s James Webb Space Telescope to calculate the amount of heat energy coming from the rocky exoplanet TRAPPIST-1 c. The result suggests that the planet’s atmosphere – if it exists at all – is extremely thin. »
Phosphorus, a key chemical element for many biological processes, has been found in icy grains emitted by the small moon and is likely abundant in its subsurface ocean. »
The work is based on new modeling and explores how oceans could exist in unlikely places in our solar system. »
Using ESO’s Very Large Telescope (VLT), researchers have found for the first time the fingerprints left by the explosion of the first stars in the Universe. »
A new NASA study offers an explanation of how quakes could be the source of the mysteriously smooth terrain on moons circling Jupiter and Saturn. »
These objects are more than 100 times brighter than they should be. Observations by the agency’s NuSTAR X-ray telescope support a possible solution to this puzzle. »
Glass beads on the moon's surface may contain nearly 300 billion tons of water, which could provide a way for astronauts on future lunar missions to get water in space, a team of 28 scientists said. »
The secret has been hiding in plain view for 40 years. »
In just a few hours of observations, the space telescope revealed a dynamic atmosphere on a planet 40 light-years from Earth. »
Using the Atacama Large Millimeter/submillimeter Array astronomers have detected gaseous water in the planet-forming disc around the star V883 Orionis. This water carries a chemical signature that explains the journey of water from star-forming gas clouds to planets, and supports the idea that water on Earth is even older than our Sun. »
Research improves search for cosmic dawn radiation, tests theories of galaxy formation. »
In the search for life elsewhere in the Universe, scientists have traditionally looked for planets with liquid water at their surface. But, rather than flowing as oceans and rivers, much of a planet’s water can be locked in rocks deep within its interior. »
The veteran rover captured a dazzling sunset at the start of a new cloud-imaging campaign. »
Space agencies and private companies around the world have been scheduling their own lunar missions to take place over the coming years, and it will be quite complicated having to coordinate with each other when they use different time zones. »
The research uses archival NASA data to show that Venus may be losing heat from geologic activity in regions called coronae, possibly like early tectonic activity on Earth. »
Among other discoveries made by the rover, rippled rock textures suggest lakes existed in a region of ancient Mars that scientists expected to be drier. »
NASA’s newest astrophysics observatory wasn’t designed to look for small objects in our solar system, but scientists using its Mid-Infrared Instrument may have done just that. »
Gemini North Telescope on Hawaii reveals first dormant, stellar-mass black hole. »
Little ‘hurricanes’ that form in the discs of gas and dust around young stars can be used to study certain aspects of planet formation, even for smaller planets which orbit their star at large distances and are out of reach for most telescopes. »
Using data from NASA’s Transiting Exoplanet Survey Satellite, scientists have identified an Earth-size world, called TOI 700 e, orbiting within the habitable zone of its star – the range of distances where liquid water could occur on a planet’s surface. The world is 95% Earth’s size and likely rocky. »
Cube-shaped snow, icy landscapes, and frost are all part of the Red Planet’s coldest season. »
Filled with rock, the sample tube will be one of 10 forming a depot of tubes that could be considered for a journey to Earth by the Mars Sample Return campaign. »
After revealing a trove of details about the moons Ganymede and Europa, the mission to Jupiter is setting its sights on sister moon Io. »
An international team of astronomers, including scientists at the Universities of Cambridge, Hertfordshire and Oxford, has reported the discovery of the earliest galaxies ever confirmed in our Universe. »
A team led by researchers at the University of Montreal has found evidence that two exoplanets orbiting a red dwarf star are "water worlds," where water makes up a large fraction of the entire planet. These worlds, located in a planetary system 218 light-years away in the constellation Lyra, are unlike any planet found in our solar system. »
Aside from a tapestry of glittering stars, and the glow of the waxing and waning Moon, the nighttime sky looks inky black to the casual observer. But how dark is dark? »
NASA’s James Webb Space Telescope just scored another first: a molecular and chemical profile of a distant world’s skies. »
NASA’s James Webb Space Telescope has revealed the once-hidden features of the protostar within the dark cloud L1527, providing insight into the beginnings of a new star. »
A team of astronomers have found that planet formation in our young Solar System started much earlier than previously thought, with the building blocks of planets growing at the same time as their parent star. »
