What is the maximum magnification of the Hubble Space Telescope?
HST’s focal length is about 57,600 mm, and magnification is the telescope’s focal length divided by the focal length of the eyepiece. For a 40 mm eyepiece, this works out to 1440x, which is well within the limits of a telescope that size. If maintaining surface brightness is a criteria, then 400x is the limit.
What is the range of the Hubble telescope?
about 10-15 billion light-years
What is the largest telescope in space?
Telescope Webb
How far is the Hubble telescope from Earth?
about 547 kilometers
What is a disadvantage of a reflecting telescope?
Reflecting telescopes have a few disadvantages as well. Because they are normally open, the mirrors have to be cleaned. Also, unless the mirrors and other optics are kept at the same temperature as the outside air, there will be air currents inside the telescope that will cause images to be fuzzy.
What type of telescope does NASA use?
the Hubble Space Telescope
Can you visit an observatory at night?
Visitors can tour the observatory by day, or head back after sundown, when they can get a look at the night sky through two dedicated visitor telescopes. Unfortunately, though, visitors can’t have access to the research telescopes at night—the lights from their cars would block the view.
Can I look through a telescope in an observatory?
So, can “regular people” visit an observatory? Many facilities offer tours and some give peeks through a telescope on public nights. Among the best-known public facilities is Griffith Observatory in Los Angeles, where visitors can look at the Sun during the day and look through a professional scope at night.
What are we looking at when we see the Milky Way?
When we look to the edge, we see a spiral arm of the Milky Way known as the Orion-Cygnus Arm (or the Orion spur): a river of light across the sky that gave rise to so many ancient myths. The solar system is just on the inner edge of this spiral arm.
