Four of Our Favorite SOHO-discovered Comets
On June 15, 2020, a citizen scientist spotted a never-before-seen comet in data from the Solar and Heliospheric Observatory, or SOHO — the 4,000th comet discovery in the spacecraft’s 25-year history. The comet is nicknamed SOHO-4000,...

NASA | Many Views of a Massive CME
On July 23, 2012, a massive cloud of solar material erupted off the sun's right side, zooming out into space. It soon passed one of NASA's Solar Terrestrial Relations Observatory, or STEREO, spacecraft, which clocked the CME as traveling...

11 Years Charting Edge of Solar System
Far, far beyond the orbits of the planets lie the hazy outlines of the magnetic bubble in space that we call home. This is the heliosphere, the vast bubble that is generated by the Sun’s magnetic field and envelops all the planets. The...

It's Surprisingly Hard to Go to the Sun
The Sun contains 99.8 of the mass in our solar system. Its gravitational pull is what keeps everything here, from tiny Mercury to the gas giants to the Oort Cloud, 186 billion miles away. But even though the Sun has such a powerful pull,...
