The Japanese Hayabusa 2 spacecraft dispatched the first of a set of smaller missions that will explore asteroid 162173 Ryugu.
A recent analysis of data from NASA's Dawn spacecraft reveals the role of cryovolcanism past — and likely present — on the giant asteroid Ceres.
Cassini's legacy sheds more light on the strange mystery of Saturn's northern polar hexagon.
Juno observations reveal that Jupiter’s magnetic field has a wacky plume.
Scientists predicted the shape of the solar corona as it would be seen during the August 21, 2017, total solar eclipse. Observations confirmed that they got the broad strokes right.
NASA's Osiris-REX asteroid sample return mission spies target Bennu for the first time. Now the spacecraft is setting up for its close approach in December.
After more than a decade of tantalizing but inconclusive hints, new research shows convincingly that patches of water ice lie exposed on the floors of many permanently shadowed lunar craters.
The Opportunity rover fell silent in June after nearly 15 years of work on the Red Planet. Now the dust storm that prevented its batteries from charging is clearing.
The unique Parker Solar Probe launched on Sunday, August 12th, set to fly faster and come closer to the Sun than any spacecraft before it.
New results show that the Medusae Fossae Formation, a set of broad and enigmatic plains, provides most of the fine dust found everywhere on the Martian surface.
Scientists studying microscopic minerals found in a meteorite have discovered evidence of the feistiness of the toddler Sun.
A radar instrument on one of the oldest operational Mars orbiters has discovered possible evidence of liquid water on Mars.
Over the past 18 months, astronomers have painstakingly tracked a dozen tiny moons that they found circling the giant planet Jupiter.
A new National Academies study assesses NASA's efforts to protect neighboring worlds from contamination and recommends ways the space agency could do a better job.
With opposition only weeks away, will the current global dust storm finally break? We look at the prospects.
The expedition off the coast of Washington state performs a first, recovering meteorite fragments from a documented fall.
Scientists aren't comfortable yet saying that organics on Saturn's icy moon arose from life, but they have an idea of what to look for next.
Researchers have found that 'Oumuamua — the first confirmed object to enter the solar system from interstellar space — was a comet, releasing just enough gas to subtly change its course.
We got a peek at a new worldlet in the inner solar system this week, as the Japanese Aerospace Agency's (JAXA) Hayabusa-2 gave us our first good looks at the tiny asteroid 162173 Ryugu.
Will Mars soon be hidden under a veil of dust? Let's hope not. We explore the current storm and the planet's upcoming close opposition.
Scientists have discovered that a supervolcano likely created a mysterious rock formation on Mars some 3 billion years ago.
The dust storm on Mars that broke out at the end of May is now affecting the skies across the entire planet.
A new study sheds light on an old mystery surrounding anomalous readings from the Apollo landing sites.
New research shows that interactions between small objects beyond Neptune’s orbit —and not a hypothetical Planet Nine — could be the reason some far-flung solar system objects “detach” from their original orbits.
The Curiosity rover has detected organic molecules in ancient rocks on Mars.
