Cosmic latte is the average color of the galaxies of the universe as perceived from the Earth, found by a team of astronomers from Johns Hopkins University (JHU). In 2002, Karl Glazebrook and Ivan Baldry determined that the average color of the universe was a greenish white, but they soon corrected their analysis in a 2003 paper in which they reported that their survey of the light from over ...
A color–color diagram is a means of comparing the colors ... and South Pole Telescope used SLR in the measurement of redshifts of galaxy clusters. [4] The blue-tip ...
The galaxy color–magnitude diagram shows the relationship between absolute magnitude (a measure of luminosity) and mass of galaxies. A preliminary description of the three areas of this diagram was made in 2003 by Eric F. Bell et al. from the COMBO-17 survey [1] that clarified the bimodal distribution of red and blue galaxies as seen in the ...
In astronomy, a blue compact dwarf galaxy (BCD galaxy) is a small galaxy which contains large clusters of young, hot, massive stars. These stars, the brightest of which are blue, cause the galaxy itself to appear blue in colour. [ 15 ]
NGC 3184, the Little Pinwheel Galaxy, is a spiral galaxy approximately 40 million light-years away [2] in the constellation Ursa Major. Its name comes from its resemblance to the Pinwheel Galaxy. It was discovered on 18 March 1787 by German-British astronomer William Herschel. [3] It has two HII regions named NGC 3180 [4] and NGC 3181. [5]
A1689B11 is an extremely old spiral galaxy located in the Abell 1689 galaxy cluster in the Virgo constellation. [21] A1689B11 is 11 billion light years from the Earth, forming 2.6 billion years after the Big Bang.

The blue suffix (e.g. L3blue) indicates unusual blue near-infrared colors for L-dwarfs without obvious low metallicity. [ 116 ] Young brown dwarfs have low surface gravities because they have larger radii and lower masses compared to the field stars of similar spectral type.
