... Bad Astronomy . ... Bitesize Astronomy . ... The last step encompassed them all with galaxies , and how we discovered that the Milky Way was not the entire Universe. ... And just like those star clusters, there are different kinds of galaxy clusters. ... There are vast clusters of clusters, called superclusters, which contains hundreds of thousands or even millions of galaxies. ... Our own Galaxy has 400 billion stars in it, yet there are clusters out there with millions of galaxies like our own. ...

... However, while low mass stars are usually found to form in loose groups with densities of a few stars per cubic parsecs, high mass stars are known to form in dense clusters with up to 10000 stars per cubic parsec. ... We have undertaken a survey of a cospicuous number of fields around intermediate mass young stars (Herbig Ae/Be stars, HAeBe) with the aim of detect and characterize the groups of young stars that may have formed together with the HAeBe star. ...

However others are less pessimistic and it has even been claimed that the mysterious ?Wow! signal? received in 1977 originated from the direction M55.б  Sadly, this still unexplained pulse of radio energy originated from a location rather to the northwest of M55 so I doubt if the source was this cluster (if indeed the signal was genuinely of extraterrestrial origin). ... Mysterious Wow! ...

... Globular star cluster Palomar 13 has roamed the halo of our Milky Way Galaxy for the last 12 billion years. The apparently sparse cluster of stars just left of center in this composite color digital image, it is one of the smallest, faintest globular clusters known. ... The Reflecting Dust Clouds of Orion . ... In this wide-angle view, the Bubble nebula lies at the center of a larger complex of shocked glowing gas about 11,000 light-years distant in the fair constellation Cassiopeia. ...

... Millions and billions of stars were bound by gravity into groups that we call galaxies. And gravity even confines galaxies together in packs that we call galaxy clusters . ... It shows the Spiderweb Galaxy forming at the centre of a galaxy cluster. ... Like a construction site on Earth, galaxy clusters are dusty while they are forming. ... Using one of these special telescopes astronomers have managed to look at stars being born inside the Spiderweb galaxy cluster for the first time. ...

... The submission of a formal application to the Board of Graduate Studies for admission as a graduate student in the University of Cambridge in Physics. ... Your application must be completed and submitted to the Board of Graduate Studies as soon as possible; students who are applying for admission in October 2016 should make sure it arrives sufficiently early that we can assess it at the same time as we receive our internal Astrophysics Group application form (i.e. by March 2016, see below). ...

... These Frontier Fields will combine the power of HST with the natural gravitational telescopes of high-magnification clusters of galaxies. ... We are soliciting gravitational lensing maps for the last four Hubble Frontier Fields clusters (MACSJ0717.5+3745, MACSJ1149.5+2223, AbellS1063, and Abell 370) based upon the exceptionally deep HST FF imaging and other new ancillary data. ... For the full set of proposal instructions and requirements, see the FY16 Frontier Fields Lensing Map Call for Proposals....

M31, also known as the Andromeda Galaxy, is the nearest large galaxy to our own. ... M31 is about 4 times as massive as the Milky Way. It has a substantially large population of globular clusters (about 600) than does the Milky Way. The overall star formation rate in M31 is remarkablely low compared to other spiral galaxies. M31 and the Milky Way are bound together (maybe?) in a configuration known as the Local Group of Galaxies. ... This image is another unique image. ...

... Today this year's largest group of sunspots will cross the Sun's central meridian. ... The next day, the number of spots in the group reached five, and the day after, on June 2nd, it was possible to count thirteen sunspots on solar disk, which had been clear prior to this. ... This year's two most powerful active areas, which passed across the solar disk at the beginning of May, 2009, are set to appear in the Sun's eastern sector in two days, on June 6th. ...

Many intermediate-age star clusters in the Magellanic Clouds exhibit very unusual features in their colour-magnitude diagrams that suggest they may have formed their stars over periods spanning hundreds of millions of years per cluster. ... Nonetheless, this interpretation is enticing in the context of the formation of ancient globular clusters, which almost always exhibit puzzling abundance patterns that apparently require multiple episodes of star formation to explain. ...

The CIMA users working group has been formed to discuss and decide on the future development of CIMA. Anyone interested in the future of CIMA is welcome to join the group.
