Royal Astronomical Society A team of astronomers from the University of Anitoquia, Medellin, Colombia, have discovered a graveyard of comets. The researchers, led by Antioquia astronomer Prof. Ignacio Ferrin, describe how some of these objects, inactive for millions of years, have returned to life leading them to name the group the 'Lazarus comets'. The team published their results in the Oxford University Press journal Monthly Notices of the Royal Astronomical Society. Comets are...

The odd make-up of the orbiting rocks has long tickled the curiosity of scientists, with their strange...

It is nothing new for the ESA/NASA Solar and Heliospheric Observatory (SOHO) to discover another comet "“ it has already found more than 1350. But the latest is a bit different - SOHO had spotted it twice before. For the first time, SOHO's Large Angle and Spectrometric Coronagraph Experiment (LASCO) has found a rare type of comet called a periodic comet (which flies by the Sun at regular intervals). While many SOHO comets are believed to be periodic, this is the first one that has been...
