Astronomy Mind Map

Light year- light is the distances from the sun to earth.

Orbital Period- the time its takes a planet to revolve around the sun.

Telescopes- there are 5 types of telescopes(Radio Telescope, Reflecting Telescope,Magnifying Glass, Space Based Telescope, and)

Rotation Period- the amount of time that the planets spin on there axis.

Planets- there are 8 planets, (mercury,Venus,Earth,Mars,Jupiter,Saturn,Uranus,and Neptune)

Terrestrial Planets -Composed of mainly silicate rocks or metals . (inner planets, closest to the sun)

when the universe began expanding it go called the Big Bang Theory.

Red shift is the spectrum that is moving away from Earth

Stars life cycle- a stars life is basically based on its mass/size.

Nuclear Fusion- 2 protons combine to make 1 proton-neutron pair. After that, the proton-neutron pair combines with new proton to make a nucleus with 2 protons and 1 neutron. Lastly,2 nuclei of (2p+1n) combine to make helium.

Absolute Magnitude-how bright the stars would appear if all were standard.

Apparent Magnitude-brightness of a star that appears to us on Earth.

Parallax-a shift in a stars position when viewed in different locations.

Actual Motion-changes over time

Apparent Motion-appearance that objects in the night sky move.

Hertzsprung- Russel Diagram or H-R Diagram - Gives you the luminosity and temeperature of stars.

Elliptical Galaxy are very bright and are not spiral, also it contains the oldest stars.

Irregular Galaxies are very low in mass and are rich of dust and gas, also its is the least common type of galaxy.

Spiral Galaxies have a bar of straight stars that run through them,also have a thick center and have flat arms.

Electromagnetic Spectrum-it has both electric and magnetic fields.

Doppler Effect- is the effect of a noise moving towards and away from you.

Red Shift- when electromagnetic fields are moving away from earth.

Astronomical Units- units that are measured in the galaxy

Gas Giants- large planet of low density, made up of mostly hydrogen and helium

Core- middle of the suns interior.

Corona- outer layer of the suns atmosphere.

Chromosphere-has a reddish glow, and also is 2nd layer of the suns atmosphere.

Convective Zone- the outer layer of suns interior.

Sunspots- cool,dark areas of gas within the photosphere.

Solar Flare is sudden eruptions of electrically charged particles.

Prominence-Great clouds of glowing gases,form high arches that are high above the suns surface.

Photosphere- The very first layer of the suns atomosphere.

E=mc- an equation to calculate the amount of energy produced from a specificamount of matter. ( E= energy, M=amount of matter changed, and C=speed lof light)

Radiative Zopne - The second layer of the suns interior, surronds the core.
