About the Sun

The Sun is 93 million miles (150 million kilometers) away from the Earth. It’s the only star that humanity has visited.

Solar Missions

Learn about solar missions such as Parker Solar Probe, SDO, SOHO, Stereo & Solar Orbiter. They study the star in our backyard.

Space Weather

Space weather includes any and all conditions and events on the sun, in the solar wind, in near-Earth and in our upper atmosphere.

Eclipses & Transits

A transit is when one object crosses in front of another in space. A transit is called an eclipse when it involves the Sun, Earth & Moon.

Aurora

Aurora are natural, multicolored lights displays that can primarily been seen at high latitudes, near the north and south poles.

Heliosphere

The heliosphere is the sun’s extended atmosphere that surrounds the entire solar system. It is a vast, bubble-like region of space.

Parker Solar Probe

Humanity’s First Visit to a Star

Parker Solar Probe is a historic mission, flying into the Sun’s atmosphere (or corona) for the first time! It will have 24 orbits around the sun, traveling at a top speed of 430,000 mph—the fastest man-made object ever! It can also withstand temperatures outside the spacecraft that reach nearly 2,500°F (1,377°C)!

Parker Solar Probe has now touched the sun!

The Sun Today

Current observations of the Sun as seen by the Solar Dynamics Observatory (SDO) & the Solar and Heliospheric Observatory (SOHO).

The Sun emits light in all colors. Specialized instruments can observe light far beyond the ranges visible to the naked eye. The “false colors” are chosen to best highlight features in each wavelength.
