An overnight SpaceX launch planned for early Saturday will use a booster that's already flown to space 25 times.
For the first time, astronomers have imaged dozens of belts around nearby stars where comets and tiny pebbles within them are orbiting.
Astrophysicists led by a team from Trinity College Dublin have—for the first time—imaged a large number of exocomet belts around nearby stars, and the tiny pebbles within them. The crystal-clear images show light being emitted ...
Outer space is infinite, but that hasn't stopped humans trying to impose their laws on it. There are more ways for people to travel to space than ever before, and the next few decades are likely to see the US and China sending ...
Getting a mission to the point of officially being accepted for launch is an ordeal. However, even when they aren't selected for implementation, their ideas, and in some cases, their technologies, can live on in other missions. ...
Trying to understand the makeup and evolution of the solar system's Kuiper belt has kept researchers busy since it was hypothesized soon after the discovery of Pluto in 1930. In particular, binary pairs of objects there are ...
Identifying asteroids on a potential collision course with Earth could be made easier thanks to an advancement in how to track their orbits more precisely.
Ever since William Herschel discovered Uranus in 1781, astronomers have been eager to find new planets on the outer edge of the solar system. But after the discovery of Neptune in 1846, we've found no other large planets. ...
Pluto may have been downgraded from full-planet status, but that doesn't mean it doesn't hold a special place in scientist's hearts. There are practical and sentimental reasons for that—Pluto has tantalizing mysteries to ...
A Southwest Research Institute-led team combined compositional data of primitive bodies like Kuiper Belt objects, asteroids and comets with new solar data sets to develop a revised solar composition that potentially reconciles ...
