Cosmology pictures

Do we have real pictures of galaxies?

Hubble Ultra Deep Field
This image zooms in on a patch of the sky that contains about 10,000 galaxies that lie up to 10 billion light-years away from Earth.
Astronomers use these deep-space images to look back in time and study the universe's origins and evolution..

How did we get pictures of the universe?

During its thirty years of operation, the Hubble Space Telescope has changed how we see the cosmos.
Its images, based on data returned by the telescope and carefully crafted through digital image processing, have expanded scientific understandings of everything from planets in our solar system to dark matter..

How do scientists create images of the galaxy?

They can use detectors of radio, infrared, optical, ultraviolet, X-ray and gamma-ray light to create images of stars and galaxies and other cosmic objects.
An image is just a way for scientists to plot or draw light..

How do we have pictures of other galaxies?

There's two ways to take pictures of space.

1. First is the WIDE angle, milky way shots you see with LOTS of stars.
Set up a wide angle camera pointing up, set the exposure for 0-30 seconds and take a picture (then edit, will get to that).
2. Second is with a telescope or big telephoto lens

What is the view of cosmology?

Cosmologists today believe that ordinary matter—the kind of matter we interact with every day—is just a small part of the universe.
Most scientists agree that dark energy and dark matter make up a huge percentage of the universe.
In this theory, dark energy makes up more than two thirds of the universe..
