... This project is lead by Dr Brian Schmidt and aims to measure the ultimate fate of the Universe: Will the Universe expand forever, or will gravity eventually halt its expansion, and send it crashing into the "gnaB giB" the "Big Bang" in reverse? ... Measuring distances in the Universe is extremely difficult, but by comparing the relative brightnesses of SN Ia, it is possible to measure a distance to a single object with a precision of about 7%. ...

... It should be recalled that most (99.99 percent) of the energy is dissipated by single radiopulsars in the form of relativistic particles and low-frequency electromagnetic waves which are not observable. ... This gives rise to an interesting analog of the classical reflection or heating effect (Lipunov, 1980[ 97 ]; Lipunov and Prokhorov, 1984[ 110 ]; Harding, 1991[ 64 ]; Lipunov and Nazin, 1994[ 119 ]). ...

... Bad Astronomy . ... Bitesize Astronomy . ... If you thought our tour of the solar system ended with Neptune and Pluto, you are setting your sights way too low. The planets of the solar system mark time relatively close to the Sun compared to interstellar space. Pluto orbits the Sun at an average distance 40 times that of the Earth, yet the nearest star (the Alpha Centauri system) to the solar system is a mind-numbing 260,000 times the distance of the Earth to the Sun. ... 2008 Phil Plait. ...

... The search for distant objects which can be both galaxies and quasars is one of the most important problems of observational astrphysics, because it allows one to determine cosmological parameters connected with the time of appearence and evolution of stellar systems, large scale structure of the Universe. ... Radio galaxies are important objects to be studied because they are sources of infrared-optical-ultraviolet continuum, emission lines and continual radio emission. ...

... The Sun has come all of one day away from breaking its record for the longest period of inactivity for the last decade - reaching a mid-summer low and falling into yet another state of "hibernation". Yesterday, on the first day of autumn, new sunspots appeared on the surface of the Sun following an absence of almost 50 days. ... The first low lasted 51 days, from 21 July until 11 September last year. ... Now, almost a year later, it seems the Sun has hit a new low almost as "deep" as the first. ...

Abstract -- Abundances of heavy elements decreases with increasing galactocentric distance almost in all disk galaxies. ... To explain this gradient in young objects and in the interstellar gas one has to assume that a typical disk galaxy is an open system, i.e. it expels some synthesized heavy elements into the circumgalactic space and/or accretes intergalactic gas with zero metallicity, with rates of both processes depending on the galactocentric distance. ...

Dust around Herbig Ae/Be Stars: Porous, Cometary-like Grains? ... This brings up the question, which we try to answer here, of how the grain porosity affects the observational manifestations of the dust shells of HAeBe stars: the excess infrared emission, anomalous extinction in the ultraviolet, and the peculiar behaviour of colour indices and linear polarization during deep brightness minima observed for about 25% of HAeBe stars (UX Ori, WW Vul, etc). ...

... Space flight . Crew training . ... The principle of the existing reliability level of space engineering, and first of all, of rocket-launchers is laid into the milestone of the cosmonauts training (the successful launch of "Soyuz" space vehicle is close to 1, but it is less than 1), that causes a possible landing of space crews outside the regular landing site. ... However, search operations can be hampered by difficult meteorological and geographical conditions in the region of emergency landing. ...
