The project of the informational system creation on the problem of evolution of radio galaxies, as a part of the "Big Trio" project aimed on studing of distant radio galaxies, is designed. This system allows a user to operate with simulated curves of spectral energy distributions (SED) to estimate ages and redshifts by photometry data. Authors use SEDs of several models for different types of galaxies. ... The HTTP and e-mail access is organized to this system. ...

An Ancient Universe: How Astronomers Know the Vast Scale of Cosmic Time . ... Astronomers can also determine the speed a galaxy is moving by breaking up its light into its component colors, rainbow-fashion. ... This pattern is now called "the expanding universe", since the entire universe of galaxies seems to be moving away. ...

CSIRO's newest radio telescope, ASKAP, has opened a window to a little-explored period of the UniverseтАЩs history, by using a special technique to spot a galaxy five billion light-years away. ... An absorption line was detected at z = 0.44 towards the radio source PKS B1740-517, and confirmed by optical spectroscopy to be intrinsic to the early-type host galaxy. ...

So how do we find objects on the other side of the Universe? ... The latest instruments enable us to scan large areas of sky. Using Cerro Tololo's Blanco 4m telescope and the Canada-France-Hawaii 3.5 metre telescope , we are able to scan a piece of sky larger than the size of the moon every 5 minutes to a faintness level which allows us to find Type Ia supernovae halfway across the Universe. Type Ia supernovae are very rare - but each image we take contains 50000 galaxies. ...

... Massive stars, having 10-150 masses of the Sun, with metallicities Z tens to hundreds times less than that of the Sun (Zo), are the main regulators of the galaxy formation and evolution processes in the early Universe. ... In this galaxy, using the 6 m BTA telescope, a new massive blue variable star with high luminosity (>=10 5 Sun's luminocities in visible light) was found. As far as its properties are concerned, this star falls into an LBV (Luminous Blue Variable) class of stars. ...

. This schematic diagram shows how scientists think the universe has evolved from the Big Bang to the present day. Data from the UKIRT, VLT, and Subaru observatories allowed astronomers to take four precise and comparable snapshots of the universe when it was, 2, 4, 6 and 9 billion years old, each containing hundreds of star-forming galaxies. By comparing the different snapshots, astronomers were able to accurately track what has changed over the past 11 billion years. // illustration by CXC/NASA/NOAO/KIPAC

... 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. ...

... Tidal influence on each of the galaxies in our sample is quantified by identifying and measuring the distance to the nearest companion, using a photometric technique with good completeness characteristics. ... Massnormalised starformation rates were derived using galaxy stellar masses estimated from zband luminosities Nearest companions were identified using the algorithm illustrated in Figure 1. ... Some of the lowredshift galaxies in our sample with close companions are illustrated in Figure 3. ...

... Subject: IAA Lecture, Events at WWT and Dungannon, RIA lecture, Galway A.F., ISS . ... Supernovae come in various forms, with different causes, but in general terms theyѓЉrepresent eitherѓЉthe explosive death of a giant star, or a very violent episode in the life of a binary star pair. Visually, they are the greatest explosions we see in the universe, with the exploding star sometimes becoming as bright as the combined light of all the other hundreds of millions of stars in its parent galaxy! ...

An image of the grand design of spiral galaxy M100 obtained with NASA's Hubble Space Telescope resolves individual stars within the majestic spiral arms. ...
