Other Moons

...Solar System...The innermost planets, Mercury and Venus, don’t have moons, but Mars has two. Go beyond Mars to the giant outer planets and the number of moons per planet skyrockets. Mars’ moons are small irregular-shaped bodies, perhaps captured asteroids, but Jupiter has three moons bigger than our own, a fourth that is almost as big, and 75 known small...

Europa: Jupiter’s ocean world

...Solar System. Since Greek times, it had been assumed that the Earth was the centre of the Solar System, with other objects orbiting around it. Galileo’s observation, that these moons were orbiting Jupiter and not Earth, contradicted that long-held view and instead supported Copernicus’ proposal that the Earth and other bodies moved round the Sun (heliocentricity,...

What do volcanoes tell us about the possibility of life on Mars?

...solar system’s largest volcano – 22km high and more than 500km across its base. It began to grow over 3 billion years ago, but some lava flows high on its flanks appear to be as young as 2m years, judging from the relative lack of overlapping impact craters. Craters caused by asteroid impacts show how old a surface in the solar system is – the more craters the...

Phobos – an asteroid masquerading as a moon of Mars?

...Solar System, yet remarkedly little is known about them. The existence of Phobos and Deimos remained hypothetical until August 1877 when Asaph Hall and American Astronomer finally found them within five days of one another. Upon discovery it became obvious why they had not been seen previously. They were both extremely small, with diameters of just ~12.4 km (Deimos) and...

...energy into solar as put into fossil fuels, I’m not sure that’s right, given what fossil fuels we know can do for poor people in the world. Do you know what the percentage of the world’s primary energy that comes from solar power today, to the nearest whole number, is? RH: Tiny. MR: Zero. It hasn’t even got to half a percent yet. RH: It hasn’t, and that is an...
