Here's a thorny problem: What if life doesn't always appear on planets that can support it? What if we find more and more exoplanets and determine that some of them are habitable? What if we also determine that life hasn't ...
An international team of researchers studying material from the asteroid Ryugu returned to Earth by the Hayabusa-2 Japanese space probe has found evidence that the asteroid formed in an outer part of the solar system, near ...
ESA and OHB have signed a contract to move forward with the design and construction of ESA's ambitious Comet Interceptor spacecraft, planned for launch in 2029.
Comet strikes on Jupiter's moon Europa could help transport critical ingredients for life found on the moon's surface to its hidden ocean of liquid water—even if the impacts don't punch completely through the moon's icy ...
A Martian megatsunami may have been caused by an asteroid collision similar to the Chicxulub impact—which contributed to the mass extinction of all non-avian dinosaurs on Earth 66 million years ago—in a shallow ocean ...
A new study from the University of Central Florida has found strong support that the outgassing of molecules from comets could be the result of the composition from the beginning of our solar system.
NASA's Double Asteroid Redirection Test (DART) spacecraft intentionally crashed into Dimorphos, the asteroid moonlet in the double-asteroid system of Didymos, on Monday, 26 September 2022. This was the first planetary defense ...
With an eye toward a possible return mission years in the future, Cornell astronomers have shown how smooth terrains—a good place to land a spacecraft and to scoop up samples—evolve on the icy world of comets.
A fireball spotted over Madrid has had its astronomical ancestry unearthed. While it ended its days burning up in Earth's atmosphere on 31 July this year, the fragment began its life as part of Comet 169P/NEAT, responsible ...
