Astronomers use a variety of telescopes to look at the universe. They need many different types of telescopes to look at space because each telescope shows them different things. Light comes in wavelengths from short to long. … Short wavelengths include gamma rays and X-rays.
What types of telescopes have to be placed in space?
X-ray and gamma-ray telescopes study the hottest and most explosive objects in space. Infrared telescopes study the places where stars are born and can look into the centers of galaxies. Optical telescopes study the visible light from space and ultraviolet telescopes study very hot stars.
Why do astronomers need different telescope designs?
Telescopes have to adapt to the greater distortion of the atmosphere at shorter wavelengths. C) Astronomers and engineers enjoy the challenge of making new telescope designs. D) Photons of different energy behave differently and require different collection strategies.
Which type of telescope must be launched into space to do its observations?
Hubble, the observatory, is the first major optical telescope to be placed in space, the ultimate mountaintop. Above the distortion of the atmosphere, far far above rain clouds and light pollution, Hubble has an unobstructed view of the universe.
Why do we use special telescopes to observe the universe?
The main reason we put telescopes into space is to get around the Earth’s atmosphere so that we can get a clearer view of the planets, stars, and galaxies that we are studying. Our atmosphere acts like a protective blanket letting only some light through while blocking others. Most of the time this is a good thing.
How does telescope work in space?
A telescope is a tool that astronomers use to see faraway objects. Most telescopes, and all large telescopes, work by using curved mirrors to gather and focus light from the night sky. … The bigger the mirrors or lenses, the more light the telescope can gather. Light is then concentrated by the shape of the optics.
Why is it better to place telescopes on a satellite in space rather than placing them on the ground?
Space-based telescopes like Hubble get a much clearer view of the universe than most of their ground-based counterparts. They’re also able to detect frequencies and wavelengths across the entire electromagnetic spectrum.
Why are different telescopes needed for different wavelengths of light quizlet?
Photons of different energy have different wavelengths, some of which are not accessible from Earth’s surface and require different collection strategies. Telescopes have to adapt to the greater distortion of the atmosphere at shorter wavelengths.
How do different types of telescopes provide different forms of data?
Optical telescopes collect visible light. The three main types are reflecting telescopes, refracting telescopes, and catadioptric telescopes. Radio telescopes collect and focus radio waves from distant objects. Space telescopes orbit Earth, collecting wavelengths of light that are normally blocked by the atmosphere.
How do different types of telescopes work?
Most any telescope will fall into one of three catagories: refractors (which use lenses to bend light into focus), reflectors (which use mirrors that reflect light into focus), and catadioptric or compound scopes, (which use a combination of both lenses and mirrors).
Why must some types of telescopes be placed in orbit quizlet?
Why do we put telescopes in space? We want to get above the Earth’s atmosphere. … Atmosphere absorbs most of EM spectrum, including all UV and X ray and most infrared.
Why can telescopes see further into space and get more detailed images of the universe?
Earth’s atmosphere alters and blocks the light that comes from space. Hubble orbits above Earth’s atmosphere, which gives it a better view of the universe than telescopes have at ground level.
Which satellite is a unique system having different kinds of telescopes on it alone?
By viewing from the other side of the sky, the Hubble Space Telescope allows astronomers to see the universe without the distortion and filtering that occurs as light passes through the Earth’s atmosphere. Infrared and ultraviolet light are affected more dramatically by the Earth’s atmosphere.
