Researchers are asking meteorite hunters to refrain from using magnets to test the authenticity of their finds because this can destroy the specimen's magnetic memory, erasing valuable information ...

The oldest known Martian meteorites, which date to roughly 4.4 billion years ago, therefore present an “amazing chance to study the magnetic field,” says Vervelidou, of MIT and the Institute ...

Exposure to external magnetic fields (such as Earth’s) can distort a meteorite’s internal magnetic properties, which means a fresh meteorite fall is ideal for study with a cryogenic magnetometer.

Magnetic: Since most meteorites contain metallic iron, a magnet will often stick to them. For “stony” meteorites, a magnet might not stick, but if you hang the magnet by a string, it will be ...

MOST of the secondary or chondritic meteorites are composed of irregular grains of silicate, sulphide, phosphide, oxide and metal phases. They are generally thought to be fragments of secondary ...

Meteorites are disappearing into the Antarctic ice as a result of the climate crisis, ... The icy plains of Antarctica are a magnet for meteorite hunters such as Maria Valdes, ...

Found in the Sahara Desert, the space rocks contain some materials we haven’t detected on Mercury, but we’re not ruling it ...

From a small bag, Henoun took out a magnifying glass and a magnetic strip. Most meteorites contain iron-nickel, an alloy that attracts magnets and isn’t found in terrestrial rocks.

The meteorite's long bright trail looked like a fireball streaking across the sky on its way to the Eastern Townships ...
