Hobbies And Interests
Accuracy
The view from the Hubble Telescope is at a very high resolution̵2;more than 10 times clearer than a ground-based telescope. This means astronomers can use it to observe details of distant objects.
Fine Measurements
Hubble̵7;s fine guidance sensors and its spectrographs can be used to take precise measurements about the location, motion, and composition of distant objects.
Distant Galaxies
Radiation from distant galaxies arrives at Earth primarily in the infrared spectrum. Hubble carries instruments to detect this radiation.
Detecting the Unseen
Hubble can ̶0;see̶1; many things that cannot be observed by most telescopes. For example it can:
? View infrared radiation that penetrates interstellar dust.
? Detect black holes with its spectrographs.
? Find signs of dark matter with high-resolution images.
The Nature of the Universe
The Hubble Telescope̵7;s wide variety of observations supply key information on how the universe began and developed. For example, Hubble played a major role in showing that the universe is expanding at an accelerating rate.
