Life Cycle of a Star and Exploring our Solar System

1

The Nebula is step number __ in the life cycle of both star sizes.

Nebula

Cloud of gas and dust.

2

The Protostar is step number _ in the life cycle of both star sizes.

Protostar

Condensed spinning cloud of dust & gas.

3

The Main Squence is step number _ in the life cycle of both star sizes.

H into He

A Main Squence star fuses _____ ___ ______.

Main Squence

A stable, balanced star fusing H→ He.

4

The Red Giant is step number _ in the life cycle of a average star.

Red Giant

A expanding large, cool, bright star that fuses up to Carbon.

Carbon

A Red Ginat fuses up to which element?

5

The Planetary Nebula is step number _ in the life cycle of a average star.

Planetary Nebula

An expanding outer shell of gas surrounded core. Expands until outer shell drifts away.

6

The White Dwarf is step number _ in the life cycle of a average star.

White Dwarf

A Star that collapsed from gravity and stopped fusion. A Dim, hot, dense core of a star.

4

The Red Supergiant is step number _ in the life cycle of a massive star.

Red Supergiant

A Star where all the hydrogen in the core is “fused” up- when there is no more outward pressure to support the star, gravity takes over and the star collapses. A large, cool, bright star fuses elements up to Iron.

5

A Supernova is step number _ in the life cycle of a massive star.

Supernova

Fusion works with gravity to quickley collapse the star causing a massive stellar explosion sending a shockwave outward- creates elements heavier than iron.

6

A Black Hole or Neutron Star are step number _ in the life cycle of a massive star.

Black Hole

For stars more than 5 times the mass of the sun, the core continues to collapse forcing all the matter into an infinitely small point, the pressure collapses creating a reminat of an extremely massive star with gravity so strong that light cannot escape.

Neutron Star

For stars 2-5 times the mass of the sun, the core continues to collapse, forcing electrons into the nucleus creating a “ball of neutrons. This creates a dense stable star made of neutrons.

Nuclear Fusion

________ _______ marks the birth of a Star.

Hydrogen Fusion

The end of _____ ______in the core, marks the death of a Star

Mass

What determines the path a star will follow throughout its lifetime?

Mercury Missions

This space programs launched the first U.S satellite and launched the first American into space. Also launch first astronaut, John Glenn, into orbit of Earth (3x) almost 5 hrs in space- 1962.

Sputnik

The first artificial satellite to orbit Earth. Soviet Union launched this.

Gemini Missions

These mission launched human space flight missions and practice missions for moon landing.

Apollo Missions

These missions land 12 astronauts and landed first man on the moon. Launched the first americna space station.

Neil Armstrong

First man on the moon.

Skylab

First American Space Station.

Space Shuttle Program

Used a reusable Orbiter-could be launched frequently. Launched Columbia and the Challenger. Helped build the ISS.

ISS

A cooperative effort between countries to create a working laboratory and consistent human presence in space.

Hubble Space Telescope

A space telescope that studied:

-scale of the universe

-life cycle of stars

-black holes

-galaxy formation
