| HR Diagram | - a tool that astronomers use to classify stars according to their luminosity(brightness), color, temperature, and evolutionary stage(age). |
| Nebulae | - clouds of dust and gas that are mainly made up of hydrogen |
| Main Sequence | - place where most stars are for the majority of their life |
| Red Giant | - When stars run out of hydrogen, they start fusing helium, and when the forces are unbalanced, the core contracts |
| Red Supergiant | stars with a solar mass of 10+ become red super giants. They are bigger but have a shorter life-span than red giants(most likely because they burn brighter for a shorter period of time) |
| Black Hole | forms when the initial solar mass of a star is greater than 30 |
| Neutron Star | After the explosion, a neutron star is formed. They are small but really dense |
| Supernova | - the red super giant phase ends when a supernova occurs. When they run out of hydrogen, they fuse helium - this happens over several months |
| Massive Star | - any star larger than eight solar masses during its regular life time is considered a massive star |
| Regular Star | -a star under eight solar masses in its life time |
| Contour Lines | - represents when a variable remains equal |
| Contour Intervals | -a fixed change in the variable between two contour lines |
| Radio Telescope | - looks at radio emissions from planetary objects Uses: -monitors signals from other planets, stars, and space objects Parts: -DISH: reflect the radio waves toward the antenna -ANTENNA: gathers radio waves and transmits them to receiver -RECEIVER: takes radio waves received by the antenna and converts them into electrical signals - AMPLIFIER: used to make the signal stronger -COMPUTER: used to interpret radio signal data |
| Rover | TASKS: -Take pictures of surface -Check for signs of life -It can reach up to 3 feet away from itself -Test rock samples -Sends data back to NASA -Keeps itself warm PARTS: A body :Protect the various parts of the rover Propulsion: A way to move Communication equipment: A way to talk to and listen to people on Earth Computer:Process information sent from scientist at NASA Sensors:Help gather information about the surface Energy Supply: It needs to keep all the sensors working |
| Apollo 13 | - a mission to mars that was called a "successful failure" because they did not reach the moon but NASA was able to get the astronauts home safely during drastic conditions. - many things went wrong during this mission |
