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.

NASA’s New Horizons space probe, 10 days from a one-shot encounter with enigmatic Pluto, stopped collecting science data Saturday after a technical problem interrupted the spacecraft’s tightly-choreographed flight plan.
On 13 September 2015, the ESA/NASA Solar and Heliospheric Observatory (SOHO) discovered its 3,000th comet, cementing its standing as the greatest comet finder of all time. The comet was spotted in SOHO’s data by Worachate Boonplod of Thailand — a citizen scientist typical of the NASA-funded Sungrazer Project volunteers responsible for 95 percent of SOHO comet discoveries.
