The origin of Phobos and Deimos, the two Martian moons, has been a mystery to astronomers. These two bodies are a fraction of the size and mass of the Moon, measuring just 22.7 km (14 mi) and 12.6 km (7.83 mi) in diameter. ...
The ocean floor is famously less explored than the surface of Mars. And when our team of scientists recently mapped the seabed, and ancient sediments beneath, we discovered what looks like an asteroid impact crater.
Even before its launch, NASA's Lucy mission was already on track to break records by visiting more asteroids than any previous mission. Now, after a surprise result from a long-running observation campaign, the mission can ...
For a long time, our view of Ceres was fuzzy, said Scott King, a geoscientist in the Virginia Tech College of Science. A dwarf planet and the largest body found in the asteroid belt—the region between Jupiter and Mars speckled ...
On the heels of Tuesday's release of the first images from NASA's James Webb Space Telescope, data from the telescope's commissioning period is now being released on the Space Telescope Science Institute's Mikulski Archive ...
One look at the Planetary Decadal Survey for 2023–2032, and you will see some bold and cutting-edge mission proposals for the coming decade. Examples include a Uranus orbiter and probe (UOP) that would study Uranus' interior, ...
Meteorites hit New Zealand three or four times a year, but the fireball that shot across the sky above Cook Strait last week was unusual.
The story of our solar system's origin is pretty well known. It goes like this: the sun began as a protostar in its "solar nebula" over 4.5 billion years ago. Over the course of several million years, the planets emerged ...
