British scientists have hailed the results of a new, experimental stem cell treatment for osteoarthritis as "astonishing."

When Mars had an ocean

Garching Bei M - Mars once hosted an ocean containing more water than the Arctic ocean. Not only that but this primitive Martian Sea covered a greater proportion of Mars’ surface than the Atlantic Ocean does on Earth.

When an iron rain fell on Earth

Not much is known about Earth’s “inner space” —its core — although scientists agree on one thing, much of the core consists of iron. But just how much iron is there remains the subject of debate.

Two unknown Earth-sized planets may be part of Solar System

Scientists tracking the orbits of objects on the extreme edge of our solar system believe that there is a good chance that two planets, at least as large as Earth may exist out there.

NASA's Dawn spacecraft viewed this Cerean crater, which is covered in ridges and steep slopes, called scarps on Dec. 23, 2015. Such likely resulted when the crater partly collapsed during its formation. The curvilinear nature of the scarps resembles those on the floor of Rheasilvia, the giant impact crater on Vesta, which Dawn orbited from 2011 to 2012. The 20-mile-wide (32-kilometer-wide) crater is located just west of the larger, named crater Dantu at northern mid-latitudes on Ceres.

Illustration showing the scale and comparative brightness of Pluto’s small satellites. Pluto’s binary companion, Charon, is at the bottom for scale. The image illustrates that two of the moons are highly oblate and that the reflectivity among the moons varies from dark charcoal to the brightness of sand.Hubble can't resolve surface features on the moons so textures are purely for illustration purposes.

A projection of the radar data of Venus collected in 2012. Striking surface features -- like mountains and ridges -- are easily seen. The black diagonal band at the center represents areas too close to the Doppler “equator” to obtain well-resolved image data.

Scientists have found evidence of plate tectonics on Jupiter's moon Europa. This conceptual illustration of the subduction process, where one plate is forced under another, shows how a cold, brittle, outer portion of Europa's 20-30 kilometer-thick ice shell moved into the warmer shell interior and was ultimately subsumed.

An artist's concept of the Oort cloud. Note that the distance scale is logarithmic. Compared to the size of planetary orbits, the Oort cloud is very far away. If the Sun passed within 2 light years of another sun-like star, the stars' Oort clouds would overlap and their comets would intermingle.
