The Cosmic Background Explorer (COBE / ˈ k oʊ b i / KOH-bee), also referred to as Explorer 66, was a NASA satellite dedicated to cosmology, which operated from 1989 to 1993.Its goals were to investigate the cosmic microwave background radiation (CMB or CMBR) of the universe and provide measurements that would help shape the understanding of the cosmos.
The discovery of cosmic microwave background radiation constitutes a major development in modern physical cosmology. In 1964, US physicist Arno Allan Penzias and radio-astronomer Robert Woodrow Wilson discovered the cosmic microwave background (CMB) , estimating its temperature as 3.5 K, as they experimented with the Holmdel Horn Antenna .
The Monitor of All-sky X-ray Image (MAXI) is an X-ray telescope mounted on the International Space Station since 2009. The instrument uses wide field of view X-ray detectors to perform a sky survey , measuring the brightness of X-ray sources every 96 minutes (one ISS orbit).
The NASA Cosmic Background Explorer satellite orbited Earth in 1989–1996 detected and quantified the large scale anisotropies at the limit of its detection capabilities. The NASA COBE mission clearly confirmed the primary anisotropy with the Differential Microwave Radiometer instrument, publishing their findings in 1992.

Satellite flare, also known as satellite glint, is a satellite pass visible to the naked eye as a brief, bright "flare". It is caused by the reflection toward the Earth below of sunlight incident on satellite surfaces such as solar panels and antennas (e.g., synthetic aperture radar ).
