Comet ‘most pristine’ object from outer space seen in Solar System

    by Marlowe HOOD / Patrick GALEY Agence France Presse A newly observed interstellar comet is the most pristine visitor from outer space ever seen in our Solar System, according to a pair of studies released Tuesday detailing its unique characteristics. Pristine, in astronomical terms, describes a comet that has never passed close enough to a star to be transformed by its searing heat. 2I/Borisov was discovered in 2019 by Ukrainian astrophysicist Gennady Borisov […]

Comet lander shuts down after sending data

BY IRENE KLOTZ (Reuters) – A pioneering robotic spacecraft shut down on Saturday after radioing results of its first and probably last batch of scientific experiments from the surface of a comet, scientists said. Batteries aboard the European Space Agency’s Philae comet lander drained, shutting down the washing machine-sized probe after an adventurous and largely unscripted 57-hour mission. Carried aboard the orbiting Rosetta mothership, Philae floated to the surface of comet 67P/Churyumov-Gerasimenko on Thursday, but […]

Dwindling battery makes comet probe drill results uncertain

(Reuters) – European Space Agency scientists faced an anxious wait on Friday to see if a probe landed on a comet has enough power left to send results of a drill down into its surface back to Earth 500 million km (300 million miles) away. Time was getting tight after the probe, released by the Rosetta spacecraft on Wednesday after a 10-year odyssey from Earth, floated away from its planned landing site. The washing machine-sized […]
