The Messier catalogue is one of the most famous lists of astronomical objects, and many objects on the list are still referenced by their Messier numbers. [1] The catalogue includes most of the astronomical deep-sky objects that can be easily observed from Earth's Northern Hemisphere ; many Messier objects are popular targets for amateur ...
Some objects originally thought to be deep sky objects and listed in the NGC have been subsequently shown to be ordinary stars, so their inclusion in the catalog is now considered erroneous. [1] This list of stars is based on the "NGC 2000.0" version of the catalog, which lists the stars in its errata, [ 1 ] supplemented with data on each ...
This week, see the first cosmic images taken by the Euclid telescope, read 265-year-old letters, uncover the volcanic threat lurking beneath Italy, and more. New celestial images will create a 3D ...
Some of the latter may be visible in gravitational lensing in looking at deepest images such as the Hubble Ultra-Deep Field (i.e., their brief existence before their turning into supernovae). As with HD 122563 , CS22892-0052 , and CD−38 245 , HD 140283 has an excess of oxygen and the alpha elements relative to iron. [ 1 ]
