Telescopes
Used to study the stars.
Most of which are Earth-based. - Answer Telescopes
Telescopes that are able to avoid the interference of the atmosphere that Earth-based telescopes must
endure. - Answer Orbiting Telescopes
Telescope used to measure both visible and ultraviolet radiation. It is used to observe both planetary and
stellar phenomena. - Answer The Hubble Space Telescope (HST)
Produces high-resolution X-Ray images of objects in the sky. - Answer Chandra X-Ray Observatory
Telescope that studies the regions around supermassive black holes and collisions between neutron
stars. - Answer Fermi Gamma Ray Telescope
Telescope that will explore the formation of the first galaxies and the details of the formations of
planetary systems.
(This was the designated successor to the Hubble) - Answer James Webb Space Telescope
, Designed to measure small irregularities in the cosmic microwave background. - Answer Planck
Observatory
Searches for planets circling other stars. - Answer Kepler Observatory
- Has a definite internal structure.
- Energy-producing reactions occur in the central core.
- Hydrogen is converted into Helium, and protons and positrons collide.
-The mass lost in this process is turned into energy and radiated outward.
- From the central core outward, collisions of subatomic particles produce more energy. - Answer The
Sun
This area begins four-fifths of the way to the surface of the Sun.
- Convection in the hydrogen-rich material in this region brings energy back to the surface. - Answer
The convection zone
The relatively thin (about 150 kilometers thick) outer layer of the Sun. This region radiates most of the
light we see from the Sun and the heat we feel. - Answer Photosphere
The outermost halo of the photosphere.
- Only visible during a total eclipse of the Sun. - Answer Chromosphere and corona
A constant stream of particles (mostly ions of Hydrogen and Helium) from the photosphere into the
surrounding space. - Answer Solar wind
The process in which energy is produced in the Sun - Answer Fusion Process
The total energy emitted by a star. - Answer Luminosity
The brightness of a star when viewed from Earth. - Answer Apparent Magnitude
