JPL's measured gravity and radius put a surface-grazing Deimos orbit near 14.2 km/h and local escape near 20.1 km/h, although Mars and the moon's irregular shape complicate real flight.
NASA’s Parker Solar Probe has spent the past few years flying repeatedly through the Sun’s corona, the outer atmosphere where temperatures run to more than a million degrees Celsius while the visible ...

A splinter of bone barely two centimetres long sat in a Siberian collection for years, unlabelled among thousands of unidentified scraps, and it turned out to be a birth certificate. It had been dug ...
What if the part of a battery you never think about, the fluid that sits between the electrodes, could be made from the shells your last seafood dinner left behind? That is roughly what a team led by ...
Pillow lavas look like a heap of stone beanbags, slumped one over another where molten rock hit cold seawater and stiffened on the spot. The ones exposed across a stretch of Western Australia’s ...
The line, in one form or another, is one of the most cited things Albert Einstein is said to have written. The version that travels furthest is the one above: “The most incomprehensible thing about ...
Earth has a centre of mass, but it is not a point permanently fixed inside the rock. Water, air and snow move across the planet through the seasons. Because they have mass, those migrations move the ...
According to the WMO, the meteorological station at Verkhoyansk has been observing temperatures since 1885, one of the longer records anywhere in the high north. The town has a population of slightly ...
