how do we get pictures of deep sky objects?

Question

if we can't get pictures of pluto, then how can we get photos of deep sky objects like galaxies, nebulas and clusters?

Answer 1

You can get pictures of Pluto.

Answer 2

Depends on what you mean by "pictures".

You can spot Pluto as a star-like dot in an 8 to 12 inch aperture telescope from a dark sky site. However its angular size is very small (something like 0.1 seconds of arc.) Many galaxies and nebulae, despite being very far away, have much bigger angular sizes (several arcminutes or more, about 1000 times bigger than Pluto.) Obviously they must be very large objects.

Once the New Horizons probe passes Pluto in 2015 (assuming nothing important fails, the cameras work and we get the data back) we'll obviously have much better pictures.

Answer 3

There are several methods.

Old fashioned telescopes can exist places where the night sky is not cluttered with lights from civilization. The magnification is pretty powerful. This kind of technology was used over a century ago by astronomers to discover objects in our solar system like Pluto in the first place.

Satelites can go into orbit to look various places in the sky, and not have to worry about distortions of our atmosphere or lights from passing motorists etc.

Some scientific instruments are not working with visible light spectrum, but radio, other parts of electromagnetic spectrum, and observe wobble in path of other objects and from that deduce what must be causing it.

Answer 4

Pluto only reflects sunlight from it's surface, galaxies and other objects in deep space produce a lot of light, this light will travel great distances.

Answer 5

the biggest reason is because pluto is so far away from our sun and so very tiny. there is little light from our sun to reflect off of pluto. nebulae and galaxies have billions of stars in them lighting them up. remember we do not see actual objects, on earth or in space, but the light reflecting off of them. you can go to http://hubblesite.org and see so so pictures of pluto and fantastic pictures from deep space, but it is worth the visit to that site.

Answer 6

They are emitting far more light than Pluto is reflecting from the Sun. Pluto is a small rock in space compared to anything else - even though they are much further away, they are much MUCH bigger and brighter.
