Are you excited to spot Comet NEOWISE as it pops into view in the night sky? Do you want to try your hand at photographing the cosmic snowball?
Comets are remnants from the early days of the solar system, billions of years ago. Primarily made of ice and dust, these "dirty snowballs" orbit the sun and in habit the Oort cloud, an area in the outskirts of the solar system beyond Pluto. As comets approach the inner solar system, solar wind from the sun can sweep dust back into a long tail. When these comets are close enough to Earth, they can appear as dazzling objects in the night sky. Space probes from Earth have visited several comets to learn more about their composition.

Astronomers are buzzing about Comet NEOWISE, which observers under clear, dark skies in the Northern Hemisphere can currently see with the naked eye.
Images of bright comet C/2020 F3 (NEOWISE) show signs of a sodium tail, giving scientists fresh insight on what's happening on the surface.
See photos of Comet C/2020 F3 NEOWISE, which is bright enough to spot with the naked eye, seen from Earth and space.
NASA's record-breaking Parker Solar Probe has given us a great new look at the gorgeous comet that's been gracing our predawn skies.
Comet NEOWISE is starting to put on a show for skywatchers, and not just those of us restricted to Earth's surface.
Astronauts caught a stunning natural light show this weekend from a comet that has been dazzling skywatchers on Earth as well.
A spacecraft that launched a quarter century ago to study the sun has discovered its 4,000th new comet in a spree of serendipitous science.
You'll need a minute to take it all in, there's a lot going on in this stunning view of the inner solar system, including a comet, Mercury and some solar weather.
The weirdness of our solar system's first known interstellar visitor stems from a very unusual composition, a new study suggests.
Last month, Comet ATLAS shattered skywatchers' hopes of a brilliant display when it began crumbling — but scientists have spotted a new serendipitous opportunity to study its rubble.
During the next couple of weeks we'll have a chance of seeing a new comet as it sweeps past the sun — that is, if the comet doesn't fizzle first.
Comet ATLAS has disintegrated before our very eyes, and two new images from the Hubble Space Telescope show the comet has crumbled into 25 pieces.
Skywatchers had high hopes that a comet called ATLAS would light up the night sky this spring, with forecasts suggesting it could become bright enough to see with the unaided eye.
