How far can Hubble telescope see? In order to avoid the interference of the earth's atmosphere, Hubble telescope is located in an orbit about 575km above the ground, but at this height, it can work quietly in an environment of "isolation from the outside world" and can clearly see farther than any celestial telescope on the ground. The photo is the "gn-z 1 1" galaxy observed by Hubble on March 3rd, 2065438. "gn-z 1 1" is located in the direction of Ursa major, with a distance of 65.438+034 billion light years, and is the farthest galaxy observed by Hubble.
What does the Hubble telescope look like to Pluto? 1 light-year is the distance that light travels in a vacuum 1 year, which is about 9 trillion 460 billion kilometers, but the average distance between Pluto and us is about 5.9 billion kilometers, which is close to 5.9 billion kilometers compared with GN-Z1phase difference134 billion light-years. People think that Hubble can photograph Pluto very clearly, but in fact it is not.
Hubble photographed Pluto. In Hubble's lens, Pluto looks very vague and can't see the details of Pluto. Hubble can see the Milky Way after 65.438+034 billion light years. Why can't it see Pluto after 5.9 billion kilometers? Take a look next time. Why can Hubble telescope see the Milky Way after 65.438+034 billion light years but not Pluto? Ideally, we can put it in front of an image of an optical system, such as a delicate geometric figure produced by the system, but in fact this does not exist, because light is flowing, so it is produced by light diffraction in our spare time. In this case, we can create our optical white point imaging system as much as possible, which is called "Eriko".
