Mercury Has an Eleven-Mile-Thick Layer of Diamonds, Scientists Find

A new research suggests that underneath, the tiny world harbors a glittering interior fit to be the jewel in the crown of our Solar System.

Mysterious 'Singing' Plasma Waves Detected Around Mercury

So-called chorus waves have been recorded at Earth, and Jupiter, and Saturn; and observed at Uranus and Neptune. Now, international scientists have detected them whistling around Mercury.

Mercury is still getting smaller

Mercury has shrunk by7 km. Most of this happened long ago, but now we have evidence that it continues. 

Mercury appears to have its own aurora

Data collected by the BepiColombo spacecraft traces the causes of the strange aurora, which course through the planet's weak magnetosphere.

BepiColombo mission is heading to Mercury

Scientists are still preparing for the crucial fly-by of Earth by the joint European–Japanese BepiColombo mission to Mercury on 10 April, despite COVID-19 quarantine.

Ancient Mercury Had the Right Stuff For Life

Mercury, the closest planet to the Sun, is one of the last places we think about when considering the potential for life in the solar system. New research suggests the planet's interior once contained the basic ingredients for life.

The Intense Heat from the Sun Helps Ice Form on Mercury

The planet’s extreme daytime heat combined with the super-cold (minus 200-degree Celsius) temperatures in the permanently shadowed craters might be acting like an “ice-making chemistry lab.”

Planet Mercury Has Solid Inner Core Same Size as Earth's

Mercury is now the second rocky planet—after Earth—for which we have evidence of a solid inner core. It’s not an exact value, but the mere presence of a solid inner core helps to understand how the planet generates its magnetic field.

Ariane 5 launches two satellites on 7-year voyage to Mercury

The project is only the second, after NASA’s MESSENGER mission, to attempt putting a spacecraft into orbit around the solar system’s innermost planet and is one of the most technically challenging missions.

Mercury's thin, dense crust

A planetary scientist has used careful mathematical calculations to determine the density of Mercury's crust, which is thinner than anyone thought.

NASA Studies Our 'Middle-Aged' Sun That Is Losing Mass

As our sun gets older, it's losing mass, and so its gravitational pull becomes weaker. As a result, the orbits of all the planets in our solar system are expanding.

Scientists Discovered a Mind-Boggling Chasm on Mercury

Larger than the Grand Canyon, wider and deeper than East Africa’s Great Rift Valley, Mercury’s newly-discovered “Great Valley” boggles the imagination. But it’s more than size that makes this geologic feature remarkable.

First Global Topographic Model of Mercury

NASA's MESSENGER mission has unveiled the first global digital elevation model (DEM) of Mercury, revealing in stunning detail the topography across the entire innermost planet and paving the way for scientists to fully characterize Mercury's geologic history.

First Mission to Mercury

As the team of scientists behind NASA’s MESSENGER spacecraft eagerly awaits the craft’s entry into Mercury’s orbit on 17 March, we could soon get answers to questions about the origin, composition, interior structure and geological history of this mysterious planet.
