Planning a successful trip can be challenging, especially when your destination is in outer space. Even before liftoff, space missions require extraordinary amounts of scientific preparation and data analysis to succeed, ...
Using advanced new simulations, a team of astronomers in the U.S. has developed a promising new theory for how giant, gaseous exoplanets migrate into stiflingly close orbits around their host stars. Led by J. J. Zanazzi at ...
Astronomers using the European Southern Observatory's Very Large Telescope (ESO's VLT) have found a rare disk of debris around a dead star that provides a glimpse of what may happen to our solar system. Unlike in similar ...
The European Space Agency's Hera spacecraft for planetary defense has resolved its two target asteroids separately for the first time, revealing the binary nature of the Didymos system, currently some 197 million km (122 ...
Over 1,645 Martian days, NASA's Perseverance Mars rover measured the fine and ultrafine Martian dust particles found clinging to samples of spacesuit materials that are carried aboard the rover, including particles small ...
Earth may have produced much of its water during the planet's formation, as rocky pebbles reacted with the hydrogen-rich atmosphere surrounding the young planet, according to new research published in Nature Geoscience. The ...
With a successful Mars gravity assist in its rearview mirror, NASA's Psyche spacecraft has fired up its thrusters and is accelerating toward the metal-rich asteroid of the same name. During the first leg of its journey, following ...
A new study suggests that some of the heaviest rocky planets ever reported may not be as heavy as they look. These so-called 'mega-Earths,' rocky planets weighing more than about 10 Earths, could be an illusion created by ...
Scientists at Columbia University and Imperial College London have found that the largest canyon system in the solar system is still active and shaping Mars today, billions of years after it first formed.
The interstellar comet 3I/ATLAS brought material from another planetary system within reach of our telescopes, but reading its chemistry poses a problem. Energetic particles encountered during its journey through space may ...
