The stress tolerated by IM1 before it disintegrated implies that it was tougher than iron meteorites in the solar system. This raises important questions: what was IM1’s melting temperature, thermal conductivity, material strength or electric conductivity? Given the measured over-...

Wonderful news! For the first time in history, scientists analyzed materials from a meter-size object that originated from outside the solar system. The object lit up the sky over the Pacific Ocean nearly a decade ago and its bright fireball was tracked by US government satellites. It has been my...
