Sun's Features
100

an element produced by nuclear fusion in main sequence stars

What is Helium?

100

First step of Star Cycle

What is a Nebulae?

100

a cloud of dust and gas in space

What is a Nebula?

100

The outermost layer of the sun's atmosphere

What is the Corona?

100

Colored light produced by charged particles from the solar wind and from the magnetosphere that react with and excite the oxygen

What is an Aurora?

200

size of low energy and low frequency waves

What is Long Wavelength?

200

Also known as a "Baby Star"

What is a Protostar?

200

a glowing cloud section that eventually becomes a star?

What is a Protostar?

200

center, hottest, part of the sun

What is the Core?

200

A part of coronal gas that is thrown into space from the sun

What is Coronal Mass Ejection?

300

SI unit of energy

What is Joule?

300

Step after Massive Main Sequence star runs out of hydrogen

What is a Supergiant?

300

This star changes how it is going through nuclear fusion combining Helium into larger elements

What is a Red Supergiant

300

The visible surface of the sun

What is Photosphere?

300

A loop of relatively cool, incandescent gas that extends above the photosphere

What is Prominence?

400

Law that states that the total mass of a system remains constant

What is Law of Conservation of Mass?

400

Last step of the Star Cycle for a Sun-Like Star

What is a Dwarf?

400

the small, dense core of a high-mass star after a supernova

What is a neutron star?

400

The thin layer of the sun that is just above the photosphere and that flows a reddish color during eclipses

What is Chromosphere?

400

An explosive release of energy that comes from the sun and that is associated with magnetic disturbances on the sun's surface

What is Solar Flare?

500

the action or process of combining two atomic nuclei to produce a nucleus of greater mass

What is Nuclear Fusion?

500

Step when massive star's fuel runs out, gravity gives in and the core collapses

What is a Supernova?

500

After a red giant, this is the shell of gas that is drifting away from a dying star that is stopping nuclear fusion.

What is a planetary nebula?

500

The zone of the sun's interior that is between the core and the convective zone and in which energy moves by radiation

What is Radiative Zone?

500

a form of energy that exhibits wavelike behavior as it travels through space

What is Electromagnetic Radiation?
