Discovery Space: Survey of the universe In order to understand the universe, it needs to be surveyed. Astronomers use various methods to measure the vast distances between stars and galaxies, and to study the behavior at these remote objects. If two objects radiate with the same intensity (luminosity), then the closer object will appear brighter. … Read more
THE UNIVERSE Information regarding the appearance of the universe as a whole, its origins, and how it evolved is limited, but by measuring the radiation coming from celestial bodies in combination with knowledge about the physical laws, scientists are able to create models of the universe, which are assessed by how well they match observational … Read more
Discovery Space: ASTRONOMY The magnificent, starry sky has always inspired the human imagination. A growing understanding of geography, mathematics, and physics over the millennia has ensured that astronomy has never lost its ability to help us explore new realms of the unknown. Today, modern technology continues to drive this age-old cosmic search. From the beginnings … Read more
Discovery Space: Universe And Galaxies Just by looking at the stars, one can get an idea of how infinitely large the universe must be. Countless stars and galaxies are scattered all over this enormously vast space, with immense distances between one another. Today’s scientists use radiation emitted from space, as well as state-of-the-art telescopes to … Read more
