S3 E4 — Gravity
Scientists are now probing to detect gravity waves in space and mapping the gravity patterns of the moon for the first time.

S3 E5 — Science and the Shuttle
For more than 25 years, the shuttle was our ticket to space and our laboratory in orbit.

S3 E6 — Landing on Mars
The vast majority of information being gathered about Mars is by orbiters chronicling everything they can.

S1 E13 — Venus: Death of a Planet
Exploring Venus' history and how it diverged from Earth in its formative years to become a hot, acidic, lifeless world.

S1 E5 — The Largest Black Holes in the Universe
Among the millions black holes in the Milky Way Galaxy are massive black holes with the greatest potential for destruction.

S1 E32 — Black Holes and the High-Energy Universe
Astronomers explore the fundamental workings of the universe and its energies through programs including Fermi, Swift, Chandra, NuSTAR and Hubble.

S1 E22 — Voyager: Journey to the Stars
Two Voyager spacecraft speed toward the boundary of the solar system, providing astronomers with valuable data about the cosmos.

S1 E11 — The Search for Earthlike Planets
The Kepler space telescope helps astronomers explore the galaxy for other planets like Earth that are capable of supporting life.

S1 E1 — Mutant Inferno
A warmer planet creates drier conditions and increasing lightning activity, causing catastrophic wildfires and other anomalies like "firenadoes"; megastorm events occur in California and Alberta, Canada.

S1 E2 — Mutant Megastorms
Climate change means warmer ocean temperatures and higher sea levels which are intensifying hurricanes. Some experts believe we should add a Category six to the Saffir-Simpson hurricane wind scale.
