Pluto’s tenuous atmosphere appears to have begun contracting after years of holding steady.
Now, a new study argues the surface of Venus may still bear the geological scars of those long-lost seas.
In 2010, scientists waiting to use the William Herschel Telescope in the Canary Islands captured a brief 36 minutes of images of Venus. What they discovered, hidden in the data, was a series of planetwide concentric rings in the upper atmosphere.
NASA's Perseverance rover has reached an impressive new milestone on Mars, completing the equivalent of a full marathon by driving 42.195 kilometers across the Red Planet.
Our Solar System may once have hosted not two, but three ice giants. This long-lost world could help explain why the outer planets and their moons look the way they do today.
Shalbatana Vallis is an impressive channel near Mars’s equator. It is 1300 km in length - around the length of Italy. Formed formed around 3.5 billion years ago, when huge quantities of groundwater rose up to Mars’s surface.
A team of astronomers have discovered a giant volcanic cave hiding beneath the surface of Venus.
A NASA rover has discovered more building blocks of life on Mars after carrying out a chemistry experiment never before conducted on another planet.
Now Perseverance’s ground-penetrating radar (called RIMFAX) detected older river delta buried tens of meters beneath Jezero crater.
Using archival radar data from NASA’s Magellan spacecraft, planetary researchers have identified a vast underground conduit beneath the surface in the Venusian region of Nyx Mons.
The researchers found that additional studies of the data from Curiosity show that non-biological sources they had considered don’t fully explain the organics. They conclude, therefore, that a biological source is a reasonable hypothesis.
Vast amounts of hydrogen could also be locked away in our planet's core, attached to the densely packed alloyed iron that lurks therein
The chemical math of the interior of the meteorite Black Beauty means that those little bits of rock hold up to about 11% of the sample's total water content.
By firing tiny projectiles of iron-carbon alloy from a high-speed cannon, scientists have finally demonstrated that a weird part-solid, part-liquid-like state thought to exist inside Earth's inner core is indeed possible.
A new Swiss-led study uses innovative hybrid modeling to reveal that these planets could just as easily be dominated by rock as by water-rich ices.
