ESPS Semester 1

TermDefinition
Astronomy The branch of science that deals with space, objects in space, and the physical universe as a whole.
Big Bang Theory The theory that the universe may have been created in a huge explosion at least 12 billion years ago.
Doppler Shift A change in the frequency of sound, light, or other waves.
Red Shift A shift toward longer wavelengths of spectral lines emitted by an object in space that is caused by an object moving away from the earth.
Blue Shift A shift toward shorter wavelengths of spectral lines of an object in space caused by the motion of the object toward the observer.
Frequency The number of crests of a wave that move past a given point in a given unit of time.
Wavelength The distance measured in the direction of a wave between two successive points.
Absolute Brightness The brightness a star would have if it were placed at a distance of 10 parsecs from Earth.
Apparent Brightness A number that is a measure of its brightness as seen by an observer on Earth.
Cosmic Microwave Background Radiation coming from space that originated from the Big Bang.
Universe The whole of all matter, energy, planets, galaxies, and space.
Galaxy The system of millions or billions of stars together with gas and dust held by a gravitational attraction.
Solar System The collection of eight planets and their moons in orbit around the sun with asteroids, meteoroids, and comets.
Star A fixed luminous point in the sky.
Planet A large object in space that orbits a star such as the sun and does not produce its own light.
Electromagnetic Spectrum The range of wavelengths or frequencies where electromagnetic radiation extends.
AU-Astronomical Unit The distance between Earth and our sun or the amount of distance in a light year.
Solar Nebula A Nebula cloud made from a collection of dust and gas.
Gas Giant A large planet of low density consisting of hydrogen and helium, such as Jupiter.
Nuclear Fusion A Nuclear reaction in which atomic nuclei fuse to form a heavier nucleus.
Convective Zone A region of plasma between a star's core and its visible photosphere.
Photosphere The luminous envelope of a star where the light and heat radiate from.
Chromosphere A reddish gaseous layer above the photosphere of a sun or star.
Corona A gaseous envelope of the sun and other stars.
Sunspot A spot or patch appearing on the sun's surface from time to time.
Prominence An eruption of high-density gas from a solar chromosphere.
Solar Flare A sudden eruption of intense high-energy radiation from the sun's surface.
Coronal mass ejection The release of plasma and magnetic field from the solar corona.
Light year The equal distance in length that light travels in one year.
Parallax The angular displacement of a celestial object due to being observed from the Earth instead of the Sun.
Main Sequence A continuous band of stars that appears on plots of stellar color versus brightness.
HR Diagram A scatter plot of stars showing the relationship between the stars' absolute magnitudes.
Nebula A cloud of gas and dust in outer space.
Red Giant A luminous giant star of low or intermediate mass.
White Dwarf A small very dense star that is typically the size of a planet.
Nova A star that shows a large increase in brightness and then slowly returns to its original state.
Neutron Star A small dense star that is a collapsed core of a giant star.
Pulsar A celestial object the rapidly rotates a neutron star.
Black Hole A region of space having such a strong gravitational field that no matter or radiation can escape.
Constellations A group of stars forming a pattern that is named after an apparent form or a mythological creature.
Cosmology The branch of Astronomy that involves the origin and evolution of the universe from the Big Bang Theory to today.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
