Astronomers studying a new image of the massive galaxy cluster Abell 1689 have revealed the largest known population of globular clusters to date, NASA reported on Thursday.

Black Hole Count Keeps Growing For The Andromeda Galaxy
2013-06-13 06:10:47

Astronomers have discovered an unprecedented number of black holes in the Andromeda Galaxy (M31), one of the Milky Way’s nearest cosmic neighbors, using data from NASA’s Chandra X-ray Observatory.

Predicting The End Of Stars Relies On How Much Sodium They Have
2013-05-29 12:58:12

An international team of astronomers published a paper in the journal Nature detailing how the amount of sodium in a star will help predict how its life will end.

Time exposure of SOAR telescope observing at Cerro Pachon in Chile

One challenge of ground-based optical astronomy is that photons in this regime, and nearby infrared and ultraviolet bands, get refracted in our atmosphere. The consequence is that imaging of astronomical objects can be blurred, making it difficult to identify and characterize individual objects.

Star Cluster -- Star clusters are physically bound systems of stars. In order of low compactness to high compactness (and in some sense also age) they range from stellar associations to open clusters to globular clusters. Star clusters are held together by the gravitation of their members. Due to both external (encounters with massive objects, influence of the host galaxy) and internal (encounters with other cluster members, stellar evolution) influences, clusters slowly evaporate. Their...

Globular Cluster -- A globular cluster is a cluster of stars that is spherical in shape and extremely dense towards its core. Globular clusters are usually composed of hundreds of thousands of old stars, similar to the bulge of a spiral galaxy but confined to a volume of only a few cubic parsecs. Some globular clusters (like Omega Centauri in our Milky Way, and G1 in M31) are truly massive clusters, with several million times the mass of our Sun. Such globular clusters may be the...

Galaxy -- Stars are almost always found in collections called galaxies, together with gas, dust, and large amounts of dark matter detected by its gravitational effects. These are all held together by gravitational attraction and orbit a common centre. There is some evidence that black holes may exist at the centre of some or most galaxies. Galaxies come in three main types: ellipticals, spirals, and irregulars. A slightly more extensive description of galaxy types is given by the Hubble...

Virgo A Galaxy -- Discovered 1781 by Charles Messier. The giant elliptical galaxy M87, also called Virgo A, is one of the most remarkable objects in the sky. It is perhaps the dominant galaxy in the closest big cluster to us, the famous Virgo Cluster of galaxies (sometimes also called "Coma-Virgo cluster" which is more acurate, as it extends into constellation Coma), and lies at the distance of this cluster (about 60 million light-years). M87 lies well in the heart of the Virgo cluster...

Milky Way Galaxy -- The Milky Way (a translation of the Latin Via Lactea, in turn derived from the Greek Galaxia (gala, galactos means "milk")) is a hazy band of white light across the night sky formed by billions of stars in the disc of our galaxy. The Milky Way appears brightest in the direction of Sagittarius, where the galactic centre lies. Relative to the celestial equator, the Milky Way passes as far north as the constellation of Cassiopeia and as far south as the constellation of...
