... Our Sun is part of a huge wheel-shaped collection of stars. ... Astronomers have long suspected it was a very massive black hole, and that every galaxy had such a central mass, created early in the history of the universe. ... However, unless that object happens to be headed directly at the black hole (a relatively small target) it will just swing around and fly away again, like a comet making a pass at the Sun. The velocity acquired in falling towards the black hole also helps it escape. ...

... We report on our ongoing project ``Infrared Study of HII Regions Associated with Small Clouds.' ... These IR data, combined with optical imaging (which will be obtained from the IAC-80 telescope), IRAS survey maps, and existing CO observations of the associated clouds, will allow us to undertake a detailed investigation of the gas-to-dust mass ratio, initial mass function and the star-formation efficiency in these complexes. ...

. The columns of the Sun. Sometimes in a good calm weather one may notice the light columns on the both sides of the Sun. These beams are reflected from vertically settled icy crystals, from which the cirrus clouds are formed. Some parts of columns are so bright that create the false suns. When it is strong frost these columns forcast the further temperature decreasing. Back .

... The high angular resolution CGPS images of atomic hydrogen emission reveal a wide-spread, cold atomic hydrogen component of the interstellar medium in the form of dark self-absorption cloud complexes. These clouds resemble molecular cloud complexes in structure and trace the spiral arm structure of the Galaxy. ... Nevertheless, continuum absorption studies show that some of the cold atomic hydrogen clouds have temperatures as low as 15 - 20 K --- similar to dense molecular clouds. ...

Close-up of L1544 with the water spectrum seen by Herschel, taken from the center of the pre-stellar core. ... These characteristics are used to indicate the density and motions of the water molecules within the cloud. Emission arises from molecules that are approaching the center where the new star will form, from the back of the cloud from HerschelтАЩs viewpoint. ... The absorption signature is due to water molecules in front of the cloud flowing away from the observer towards the center. ...

He said it was close to Polaris, the North Star, but he also said it was in the East. ... It's natural, I suppose, to think that such an important star should be bright, but really, that's a conceit, like thinking that the Earth is at the center of the Universe. If more people knew just why Polaris is the North Star, this Bad Idea would stop. ...
