No one saw the Chelyabinsk meteor of 15 February 2013 coming – the largest asteroid to strike Earth in over a century. Just after sunrise on a sunny winter’s day, a 20-metre, 13 000 tonne asteroid struck the atmosphere over the Ural Mountains in Russia at a speed of more than 18 km/s.
The relatively small rock exploded in the atmosphere at an altitude of 30 km, releasing about half a megaton of energy (equivalent to 35 Hiroshima-sized bombs). Two minutes later, the shockwave reached the ground damaging thousands of buildings, breaking windows and

Are there other Earth-like planets? Is there extraterrestrial life? In the quest to find planets that orbit stars other than the sun, "Earth 2.0" is the Holy Grail. Earth 2.0 is a planet similar enough to Earth to enable the existence of life as we know it. It would be the right temperature for liquid water, and it would orbit a star with a steady supply of light. Ideally, it would be close enou

Astronomers have long been aware that planetary systems are not necessarily structured like our solar system. Researchers from the Universities of Bern and Geneva, as well as from the National Centre of Competence in Research PlanetS, have now shown for the first time that there are in fact four types of planetary systems.
