• ​Came to be 13.8 BILLION years ago!

• Universe = everything that exists, including things we cannot see

• ​The universe was created by the Big Bang

• ​The universe is expanding

• The universe is made of dark matter, dark energy, and regular matter.​

​

The Universe

• There are billions of stars in the Milky Way Galaxy (the galaxy where Earth is located)

  ​

• Our Solar System is located in the Orion Arm of the Galaxy

  ​

• There are countless galaxies in the universe, all different sizes and shapes ​

​

Galaxies

​- ​Our solar system has 1 star: the Sun

- The planets in our Solar System were created by space matter spinning​ in a protoplanetary disc and, through accretion, larger masses began to orbit

- The sun is about 4.5 billion years old​

​

Solar Systems

​- ​The James Webb Telescope uses the sun shield to block heat from the Sun, Earth, and Moon and also blocks radiation in order to detect radiation from space objects

- The Sun produces energy through nuclear fusion​

- Telescopes in space help us detect wavelengths like x-rays and infrared radiation that our eyes cannot see​

Solar Systems

- Stars are made of hot gas

- Stars are blue when they are at their hottest temperature

- Sequence stars are born from nebulas (clouds of gas and dust)

- The MOST MASSIVE stars will become Black Holes

- The only star in our Solar System is the Sun

- Proxima Centauri is the closest star to the Sun, but it is NOT in our Solar System​

- Not all stars die the same way

• depending on their stellar mass, stars will follow different life and death patterns

​- After a supernova, either a nebula and neutron star OR Black Hole will form (this depends on how much mass is left over)

- A lightyear is a distance that light travels and is measured at 6 trillion miles, or 365 days
