What technology is used to study space?

Answer 1

Astronomers used to make photographic plates of stars on glass, and compare the images in a device known as a "blinker." If a star moved between two separate exposures, it was clearly NOT a star but an asteroid or comet.

Today we gather light on digital plates and stack images. Computers do much of the analysis in searching for interplanetary bodies. In addition, computer technology is used to measure variations in starlight on board the Kepler spacecraft. These variations reveal the presence of new worlds. Five new worlds (exoplanets) were announced earlier this year, and Kepler astronomers are expected to announce the discover of 700 more within the next few months--more than doubling the currently known number.

Answer 2

Computers are probably the biggest. Optical telescopes are 19th century technology, and radio telescopes were pretty well developed by the 1960's. Computers and electronic communications have been the biggest improvements since then.

Answer 3

Robot technology is now doing the lion's share of exploratory work both within our solar system and beyond. The amount of information sent back to scientists on earth from space probes and the Hubble Space Telescope will take years to sift through - and there are ever more probe missions and a new space telescope coming up.

Answer 4

They use a huge range of telescopes, from simple ones that you could have in your home, to massive ones that are located around the world in areas where there are regular clear skies. They use technology to examine light and listen for sounds from space. They use computers a lot. They use radar and other communications technology. They use a lot of photographic technology and technology for protecting themselves, like covers for lenses on telescopes studying the sun. They use all this and much more.

Answer 5

Various technologies are used to study space, including telescopes (both optical and radio), space probes, spectroscopy, and satellites. These technologies help researchers observe and collect data on celestial bodies, cosmic phenomena, and the universe as a whole.

Answer 6

Materials include telescopes, satellites, spectroscopes, and space probes.

Answer 7

Yes, of course they do. How could they study space without it?

Answer 8

They watch stars' orbit an empty, black void. Using this method they can also tell how far and big the Black Hole is.
