Mercury's iron core generates a magnetic field about one percent as strong as Earth's. The field is quite active, frequently interacting with the solar wind and funneling plasma from the sun to the planet's surface. The hydrogen and helium captured from the solar wind help create part of M...
Mercury's core is thought to be made of molten nickel-iron with a mantle of solid rock and a surface of loose rocks and dust. Information about Mercury's composition is based on data from the spacecraft Mariner 10, launched in 1973, and the probe MESSENGER, the mission for which ran fr...
What is outer space made of? What are planetary nebula made of? What is Mercury's surface made of? What is Ceres named after? What is Pluto made of? What caused Jovian planets and terrestrial planets to form differently? Which of the Solar System's gas planets have storms?
Mars is the "Red Planet" for a very good reason: its surface is made of a thick layer of oxidized iron dust and rocks of the same color. Maybe another name for Mars could be "Rusty." But the ruddy surface does not tell the whole story of the composition of this world. Dusty crust...

What type of planet is Uranus? What are Uranus' surface features? What chemical elements compose Uranus' core? What is Saturn made of? How is Uranus different from other planets? Describe the formation of Uranus. What makes Uranus unique among the gas giants?
What is out there?How did we get here?What is the world made of?The story of our search to answer those questions is the story of science.Of all human endeavours,science has had the greatest impact on our lives - on how we see the world, on how we see ourselves.Its ideas, its ...
What is Deimos made of? Deimos is a dark body that appears to be composed ofC-type surface materials, similar to that of asteroids found in the outer asteroid belt. Is Phobos man made? The unusual characteristics of Phobos, including its decaying orbit, led some scientists in the 1950s and...
You may walk by these watery oases each spring and never know the hundreds of lives inside—from tadpoles to fairy shrimp.
Mercury: Mercury is the closest planet to our sun. It circles the sun every 88 days, rather than Earth's orbit of 365 days. The surface of Mercury is rocky and resembles that of Earth's moon. It is a dense planet, but not the hottest. ...
