Image credit: ESA/NASA/SOHO/Joy Ng.ESA and NASA’s Solar and Heliospheric Observatory, or SOHO, saw a bright comet plunge toward the Sun on 3-4 August 2016, at nearly 1.3 million miles per hour. Comets are chunks of ice and dust that orbit the Sun, usually on highly elliptical orbits that carry them far beyond the orbit of Pluto at their farthest points. This comet, first spotted by SOHO on 1 August, is part of the Kreutz family of comets, a group with related orbits that broke off of a huge comet several centuries ago.
This comet didn’t fall into the Sun, but rather whipped around it – or at least, it would have if it had survived its journey. Like most sungrazing comets, this comet was torn apart and vaporised by the intense forces near the Sun.

An international team using the Gemini Planet Imager (GPI) at the Gemini South telescope in Chile has discovered a young, emerging planetary system around star HD 115600 that has remarkable similarities to our own Solar System in its infancy.
A speedy space probe barreled past Pluto for a one-shot flyby Tuesday, becoming the first spacecraft to ever visit the frozen, reddish world at the solar system’s distant frontier.
One of 10 studies sponsored by NASA to explore possible planetary missions includes one for a Pluto orbiter that also would venture into the Kuiper Belt.
