Construct an explanation of the Big Bang theory based on astronomical evidence of light spectra, motion of distant galaxies, and composition of matter in the universe.

Explainer: What are asteroids?
Leftovers from the creation of the solar system, asteroids are space rocks that orbit the sun. Let’s hope the big ones never become meteorites.

First mega-Earth found
Astronomers are puzzled by Kepler-10c. This exoplanet is rocky like Earth — but as massive as Neptune. And that challenges their accepted ideas about how planets form.

Sun sibling spotted
Separated at birth: Astronomers find a star 110 light-years away. It was born at the same time as our sun and from the same cloud of gas and dust.

Distant planet may boast the longest year
On a planet far, far away, a single pass around its sun may seem to last forever.

A ‘Goldilocks’ world?
Scientists have spotted a faraway planet that is nearly the size of Earth and could host liquid water. It's too far to visit, but astronomers say the galaxy could be littered with such potentially habitable worlds. Don't hang up yet, E.T.

Heavenly research
Groundbreaking research in astronomy landed four high school seniors spots as finalists in the 2014 Intel Science Talent Search.

Surprising rings circle comet-asteroid hybrid
It’s too small to be a planet. Yet this planet wannabe still resembles Saturn-like giants. It’s the smallest solar system inhabitant to, like them, host rings of orbiting ice.

Waves from the birth of time
Inflation is the idea that in the split-second after the Big Bang, the universe exploded into huge-ness. Although the hypothesis is 30 years old, evidence to confirm it had been lacking. Until now.

Galaxy drags trail of newborn stars
Distant galaxy plows through cluster of others, with baby stars in tow

Star cluster rockets through space
It’s the first time astronomers have ever detected a cluster of stars moving collectively at such speed.
- Animals
We are stardust
Everything making up Earth and what’s now living upon it — from trees and people to our pets and their fleas — owes their origins to the elements forged by ancient stars.

A shock to the solar system
Scientists suspect a nearby exploding star ignited the formation of the sun and planets.
