Mars is the seventh largest planet in our solar system and has been more robotically explored than any other planet outside Earth since the 1960s. Imaging with Mariner 9 in 1971 revealed the first direct evidence of water on the Red Planet. But it was only thanks to the recent ESA ExoMars and Mars Express … Read more

IIs it the seemingly incessant rain in Britain? Bad design? Or perhaps the way they are ridden or cleaned? Why do so many electric bike owners complain that their motors need to be replaced so often? Some mountain bike owners with a fourth-generation Bosch electric motor describe having four or five – yes five – … Read more
CNN — The equatorial region of Mars is home to the solar system’s tallest volcanoes, which – in addition to being as tall as three Mount Everests in some cases – are likely hiding an unexpected icy phenomenon, a new study has found. The largest – Olympus Mons – is 26 kilometers high and a … Read more

Strictly speaking, the water does not have to be fresh, but fresh water can only occur on dry land. Only when these two conditions are met can you convert … Read more

Recent studies have cast doubt on the presence of a lake of liquid water beneath the ice cap at Mars’ south pole, a discovery that initially raised hopes of finding microbial life on the Red Planet. In 2018, the European Space Agency’s Mars Express satellite detected strong radar reflections that indicated a 12-mile-long lake lay … Read more
If you throw a handful of drops on a very hot pan, you can watch them scurry around and dance. Believe it or not, these droplets actually float. If a surface is hot enough, the heat will vaporize the side of the droplet closest to it, creating a cushion of gas on which the rest … Read more

One of the most special things about Uranus and Neptune is their magnetic fields. Each of these planets has a hot mess of a magnetosphere, deviated and wildly tilted from its axis of rotation in a way not seen on any other planet. It’s not entirely clear why, but thanks to a team of researchers … Read more
