Their press release looked back at the Ring's history among Earthly astronomers and assigned its discovery to the 18th-century French astronomer Antoine Darquier, a contemporary of Charles Messier of Messier Catalog
To fully appreciate the close pairing of a double star or the galaxies of the Messier catalog
, you'll need to use the SkyScout in conjunction with a telescope.
Other appendixes present astronomical and physical constants, solar system data, the constellations, the brightest and nearest stars, stellar data, and the Messier catalog
and subsection headings have been added.
In a statement Thursday, NASA ascribed the finding to the black holes photobombing images of Andromeda (also called M31, after its position in the Messier catalog
of non-cometary objects) that were taken by the agency's Chandra X-ray Observatory, as well as optical data collected from Earth-based telescopes in Hawaii and California.
Of the thousands of galaxies in the Virgo Cluster, I'm focusing here on the 16 that are included in the Messier catalog
. Most of them are in the northern reaches of the constellation Virgo, but a handful spill over into neighboring Coma Berenices.
Shining wanly at magnitude 10.1, the Little Dumbbell Nebula, M76, is the faintest object in the Messier catalog
. But don't let that deter you from hunting down this prized planetary, also in the Perseus Milky Way.
The galaxy, which is also a part of the (http://www.ibtimes.com/nasa-releases-hubble-version-non-comet-objects-messier-catalog-photos-2604029) Messier Catalog
of non-comet objects , is about five times more luminous than our home galaxy and its center is one hundred times brighter than the Milky Way's center.
If M93 seems dim, it's because it is so far away: at 3,600 light-years it's one of the more distant open clusters in the Messier catalog
21 this year - NASA has released a new version of the Messier catalog
. The newly released images of the non-comet Messier objects were all captured by the Hubble Space Telescope.
These are from the Messier catalog
, published in installments from 1771 to 1781 by the French comet-hunter Charles Messier.
As an astronomer, I felt embarrassed that the final resting place of the man who gave us the Messier Catalog
, and is still such a towering figure in astronomy, has been so neglected.
