Telescopes
This uses a concave mirror to gather and focus light, creating an image.
What is a reflecting telescope?
The molten, conductive outer core of Earth creates this.
What is a magnetic field?
These planets all have a ring system.
What are Jupiter, Saturn, Uranus, and Neptune?
The light we see from the Sun comes from this.
What is the photosphere?
This is the time it takes for a celestial object to complete one full orbit around another object.
What is an orbital period?
This is an instrument that collects and analyzes radio waves from space.
What is a radio telescope?
This has created extreme temperatures on Venus.
What is the Greenhouse effect?
This is the most abundant element in Neptune’s atmosphere.
What is hydrogen?
A star spends most of its life as this.
What is a main-sequence star?
This is the lowest region of Earth’s atmosphere.
What is the troposphere?
What it’s called when different colors of light are brought to a focus at a different focal point.
What is chromatic aberration?
These travel through Earth’s interior and cause significant damage during earthquakes.
What are S-waves?
This planet has a density that is ¼ that of Earth.
What is Jupiter?
These are what an H-R diagram plots to classify and understand the evolution of stars.
What are luminosity (absolute magnitude) and temperature?
This is a technique that combines light from multiple telescopes to create a virtual telescope with a larger diameter.
What is interferometry?
This two-mirror telescope helps correct spherical aberration, providing a wide field of view.
What is a Cassegrain?
This is the thickest layer of Earth.
What is the mantle?
These helped determine several key properties of Jupiter's magnetic field, including its strength, axial tilt, and rotation period.
What are radio observations of Jupiter’s magnetosphere?
This is a way to compare the intrinsic brightness of stars regardless of their distance.
What is absolute magnitude (or luminosity)?
The angular resolution of a 16-inch telescope is this many times better than a 2-inch telescope.
What is 8 times?
These are a type of sensor that captures images by converting light into electrical charges.
What are CCDs (or charged-coupled devices)?
These are large, dark, relatively flat plains on the Moon's surface.
What is maria?
These bodies were first discovered when Galileo looked at a planet with a telescope.
What are the Galilean Moons of Jupiter?
This is the order of spectral classes from hottest to coolest.
What is OBAFGKM?
These are released when a proton is converted into a neutron during fusion.
What are positrons and electron neutrinos?
