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.
- Space
Scientists Say: Pulsar
These rapidly spinning dead stars send beams of radio waves into space like cosmic lighthouses.
- Space
Lightning dances through Jupiter’s skies much like it does on Earth
Data from NASA’s Juno spacecraft hint that Jupiter’s lightning extends in jagged steps as it does on Earth.
- Planets
In a first, telescopes have caught a star eating a planet
A burst of light and a cloud of dust are signs that a distant star swallowed a giant planet.

Saturn’s moon Enceladus wears a thick blanket of snow
Pits on the frosty moon reveal the snow’s surprising depth, up to 700 meters (2,300 feet) in some places.
- Planets
The dwarf planet Quaoar hosts an impossible ring
Quaoar’s ring lies outside the Roche limit. That’s an imaginary line beyond which rings aren’t thought to be stable.
- Physics
Let’s learn about the quantum realm
On the smallest scales, the universe behaves in some pretty strange ways.
