... 2001 February 16 . Star Forming Region Hubble-X . ... Cataloged as Hubble-X , many skygazers find the appearance of this extragalactic star forming region reminiscent of the most famous stellar nursery in our own galaxy, the Orion Nebula . Hubble-X is intrinsically much brighter than Orion though, and at a distance of 1.6 million light-years it is about 1,000 times farther away. Hubble-X is also about 100 light-years across compared to 10 light-years for the Orion Nebula. ... About APOD | ...

... STScI-PRC01-04 HUBBLE'S ULTRAVIOLET VIEWS OF NEARBY GALAXIES YIELD CLUES TO EARLY UNIVERSE Astronomers are using these three NASA Hubble Space Telescope images to help tackle the question of why distant galaxies have such odd shapes, appearing markedly different from the typical elliptical and spiral galaxies seen in the nearby universe. ... Light from these galaxies travels great distances (billions of light-years) to reach Earth. ... These stars emit mostly ultraviolet light. ...

The evolution of galaxies is driven by the intricate power play between magnetically driven turbulence and the mass and gravity of its comprising gas and dust, a system which governs the formation of stars in the dense cores of the interstellar medium s giant molecular clouds. ... This results in separate relations for the star formation rate depending on the Mach number of the medium, differing from each other by up to an order of magnitude. ...

... From the comfort of our day-to-day lives, it often feels like space is very far away. ... It is even made from the same basic materials or matter as everything else, which is why we find the same materials in space as at home. Astronomers have just spotted large amounts of one of these materials, called carbon monoxide, around a nearby star called Beta Pictoris. ... Beta Pictoris is surrounded by a large disc of cosmic gas and dust which has a planet inside it. ...

If material ejected from the Earth contains microorganisms and spores, the question arises whether life may be carried from planet to planet within the solar system. ... However, the solar system is tiny on the scale of the Galaxy, and it has generally been thought that the transfer of life between stars is impossible -- the microorganisms would be destroyed by cosmic rays, ultraviolet light and so on. ...

. Astronomers have used observations from HubbleтАЩs CANDELS survey to explore the sizes, shapes, and colors of distant galaxies over the last 80 percent of the universeтАЩs history. In the universe today, galaxies come in a variety of different forms and are classified via a system known as the Hubble Sequence тАФ and it turns out that this sequence was already in place as early as 11 billion years ago. // NASA/ESA

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. ...

... A radio galaxy is a galaxy that emits an unusually big amount of energy at radio wavelengths. ... Inside of each galaxy with an active nucleus (radio galaxies are among them) there must be a system of a "central machine" responsible for the colossal amount of the emitted energy from radio to gamma ranges. ... Sometimes a radio source in an active galaxy may flare again if the needed conditions appear (a new portion of matter would fall into the furnace of the "central machine"). ...
