Optical telescopes collect this type of light.
Visible light
These planets are made of rock and metal and are smaller than the other planets in our solar system.
Inner Planets
This satellite was the first artificial object launched into space.
Sputnik 1
In this layer, hot material rises and cool material sinks.
Convective zone
This is the lowest layer of the Sun’s atmosphere.
Photosphere
This type of telescope produces the clearest images because it avoids Earth's atmosphere.
Space telescope

Voyager 1 and Voyager 2
The zone responsible for carrying energy upward through moving plasma.
Convective zone
Sudden eruptions of intense energy from the Sun.
Solar flares
These telescopes collects this types of electromagnetic radiation and allows scientists to study the universe using large dishes.
Radio telescopes
Space objects that are smaller than asteroids and can burn up in Earth's atmosphere.
Meteoroids
The rovers designed to search for signs of past life on Mars.
Mars Exploration Rovers
The deepest layer of the Sun’s interior.
Core
Huge loops of plasma that extend outward from the Sun.
Prominences
This NASA observatory studies the Sun using a powerful telescope.
