Telescopes help distant objects appear bigger, but this is only one of their advantages. Telescopes can also collect light in ranges that our eyes alone cannot see, providing scientists ways of observing a whole host of material and processes that would otherwise be inaccessible.

NASA's NASA's Solar Dynamics Observatory (SDO) is hoping to use Venus's transit of the sun on June 5 to better calibrate its instruments.
Spectacular Northern Lights may be visible tonight across the northern hemisphere, following a solar eruption on Sunday night.
The new Solar Dynamics Observatory (SDO) could be as important to science as the Hubble Space Telescope, says NASA, as it releases its first close-up pictures of the sun.
