Astronomers from the Armagh Observatory in Northern Ireland have found that a recently discovered asteroid has been following the Earth in its motion around the Sun for at least the past 250,000 years, and may be intimately related to the origin of our planet. Their work appears in a paper in the journal Monthly Notices of the Royal Astronomical Society.

A team of astronomers led by Dr Gavin Ramsay of Armagh Observatory have spotted violent eruptions from an interacting pair of stars that orbit around each other every 25 minutes. Unusually, these outbursts take place at regular and predictable intervals, erupting every two months. The new observations were made using the fully robotic Liverpool Telescope sited in the Canary Islands and the orbiting Swift observatory. The results will appear in the journal Monthly Notices of the Royal...
