Plz answer if you know
1. what form of energy it detects?
2. what that energy is? (heat,light,...)
3. how the telescope works?
4. what is it used to detect?
5. how that information is used in modern astronomy?

1. The HST detects light in the near-infrared, visible, and ultraviolet range.
2. These are all forms of electromagnetic radiation, in different wavelengths. The range of the HST is about 10 µm to 10 nm.
3. It's a reflecting telescope, like most large telescopes. Except it's in space. Light enters the telescope, reflects off a parabolic mirror, and focuses on several CCD's, essentially the same thing that's in your digital camera. Except much more precise.
4. Since the telescope is outside Earth's atmosphere and any light pollution, it can detect much fainter light sources as well as wavelengths that are normally blocked by the atmosphere. It is also immune to the distortion of visible light that the atmosphere causes.
5. A whoooole lot of ways. Check this for more info:

1. Light.
2. Light...
3. Like all others: You point it at something, you take a picture.
4. Stuff.
5. Pretty much the same way as any other telescope. The fact that the telescope is outside the Earth's atmosphere makes a difference in terms of resolution, because you don't have to correct for atmospheric distortion, absorption from water vapor (when observing in near infrared), downtime due to weather conditions, etc.
