Color-magnitude diagrams for all bright stars within 1,000 light-years of the sun as determined by Mt. Wilson astronomers in 1935. (Left) Diagram without the subgiants, in which it is difficult to ...

A nine-gigapixel VISTA infrared image of the Milky Way's central region yielded a catalog encompassing over 84 million stars, a tenfold increase over previous studies. This data set, created from the ...

Mapping the galaxy is tricky business because of the inherent difficulties in measuring distances to stars. The problem boils down to determining the inherent brightness of a star, a property called ...

Astronomers have created a catalog of more than 84 million stars in the central parts of the Milky Way. This gigantic dataset contains more than ten times more stars than previous studies and is a ...

We obtained archival Hubble Space Telescope Wide Field Camera 3 observations of the NGC 1651 field in the F475W (‘B’) and F814W (‘I’) broadband filters (Methods). The corresponding colour–magnitude ...

Russell drew a simple system of coordinates with x- and y-axes, familiar to schoolchildren from geometry lessons. On this diagram, he entered the stars according to their spectral type or temperature ...

Toward in our galaxy’s center lies Terzan 5, a celestial object shrouded in mystery. For decades, astronomers thought this conglomeration was a globular cluster of a million stars that all formed ...
