NASA | Death-Defying Comets Explore the Sun's Atmosphere
To observe how winds move high in Earth's atmosphere, scientists sometimes release clouds of barium as tracers to track how the material corkscrews and sweeps around � but scientists have no similar technique to study the turbulent...

NASA | What is a Sungrazing Comet?
Sungrazing comets are a special class of comets that come very close to the sun at their nearest approach, a point called perihelion. To be considered a sungrazer, a comet needs to get within about 850,000 miles from the sun at...

NASA | IBEX: Observing the Sun's Horizon
The Interstellar Boundary Explorer, or IBEX, is the first mission designed to map the entire region of the boundary of our Solar System. As charged particles from the Sun, called the "solar wind," flow outward well beyond the orbits of...

NASA | MAVEN Magnetometer
When you navigate with a compass you can orient yourself thanks to Earth's global magnetic field. But on Mars, if you were to walk around with a compass it would haphazardly point from one anomaly to another, because the Red Planet does...

NASA | How to Cook a Comet
A comet's journey through the solar system is perilous and violent. Before it reaches Mars - at some 230 million miles away from the sun - the radiation of the sun begins to cook off the frozen water ice directly into gas. This is called...

The Formation of the Solar System and the Structure of the Sun
So we learned about the formation of the Milky Way, which is the galaxy that we live in. But where in that galaxy do we live? We live on a planet that orbits a star that we simply refer to as "The Sun", so where is that, and when did our...

Aurora around Saturn's north pole.
Collisions with charged particles in the solar wind cause gas atoms and molecules to emit light. Aurorae typically occur around the poles as charged particles are directed there by planets' magnetic fields. Imaged in ultraviolet light by...
