Do people use telescopes in space?
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.
What telescopes are orbiting Earth?
Ultraviolet
| Name | Space agency | Observing location |
|---|---|---|
| Hubble Space Telescope | NASA & ESA | Earth orbit (586.47–610.44 km) |
| Broad Band X-ray Telescope / Astro 1 | NASA | Earth orbit (500 km) |
| Extreme Ultraviolet Explorer (EUVE) | NASA | Earth orbit (515–527 km) |
| Astro 2 | NASA | Earth orbit (349–363 km) |
What type of telescope can be used routinely on the surface of the Earth during the day?
What type of telescope can be used routinely on the surface of the Earth during the DAY? Radio telescopes of modest size can’t make out as much detail (have a lower resolution) than visible light telescopes. How do astronomers overcome this limitation?
What types of telescopes can be used effectively from space?
Radio and optical telescopes can be used on Earth, but some resolution is lost due to Earth’s atmosphere. 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.
What is the name of NASA’s most famous space telescope?
Hubble Space Telescope
| Names | HST Hubble |
| Mission type | Astronomy |
| Operator | STScI |
| COSPAR ID | 1990-037B |

Is Hubble the only telescope in space?
While Hubble Space Telescope (HST) is certainly the most famous observatory in space, it is by no means the only one. Another member of NASA’s Great Observatories program is the Spitzer Space Telescope, which was launched in August 2003.
What is the most accurate method to detect Earth sized exoplanets with the telescopes and instrumentation that exist today?
Photometry is the only operational method for finding Earth-size planets in the continuously habitable zone. This unique search space is shaded green in the figure. The next planned space missions for exoplanet study will be based on astrometry and direct imaging (James Webb Space Telescope).
Which telescope can only be used above Earth’s atmosphere?
Ultraviolet observatories Other than carefully-select materials for filters, a ultraviolet telescope is much like a regular visible light telescope. The primary difference being that the ultraviolet telescope must be above Earth’s atmosphere to observe cosmic sources.
How big of a telescope do I need to see the rings of Saturn?
25x
Viewing Saturn’s Rings The rings of Saturn should be visible in even the smallest telescope at 25x. A good 3-inch scope at 50x can show them as a separate structure detached on all sides from the ball of the planet.
