What is the COBE telescope?

Answer 1

launched in 1989 by NASA

studied cosmic background radiation

viewed in infrared and microwaves

it was a space telescope and needed to be kept cool as it observed in infrared

wasn't very sensitive but it confirmed ideas about early universe

finished it's mission in 1993

Answer 2

The Cosmic Background Explorer (COBE), also referred to as Explorer 66, was a satellite dedicated to cosmology. Its goals were to investigate the cosmic microwave background radiation (CMB) of the universe and provide measurements that would help shape our understanding of the cosmos.

This work provided evidence that supported the Big Bang theory of the universe: that the CMB was a near-perfect black-body spectrum and that it had very faint anisotropies. Two of COBE's principal investigators, George Smoot and John Mather, received the Nobel Prize in Physics in 2006 for their work on the project. According to the Nobel Prize committee, "the COBE-project can also be regarded as the starting point for cosmology as a precision science".

Answer 3

The COBE (Cosmic Background Explorer) telescope was a satellite launched by NASA in 1989 to study the cosmic microwave background radiation, providing critical evidence for the Big Bang theory. It measured the temperature variations in this radiation, leading to important insights into the early universe's structure and evolution.

Answer 4

COBE stands for Cosmic Background Explorer. It is also called as Explorer 66.
