... Credit: Suprime-Cam , Subaru Telescope , NOAJ Explanation: Why are huge clouds of gas billowing from spiral galaxy NGC 4388? ... One hypothesis holds that the gas was stripped away as NGC 4388 made its way through the intergalactic medium of the Virgo Cluster . A competing hypothesis holds that the gas is all that remains of a smaller galaxy that was gravitationally deconstructed by the larger NGC 4388. ... Publications with keywords: NGC 4388 - gas . ...

... A reconstruction method of 3D vector velocity field (three components of velocities) of gas in disks of spiral galaxies from observed line-of-sight velocity field is proposed. This method is based on Fourier analysis of observed velocity field. ... The knowledge of velocity field in spiral galaxies allows to clarify the nature of the galactic structures and mechanisms of their formation. ...

... 2001 July 25 . Hot Gas Halo Detected Around Galaxy NGC 4631 . ... Explanation: Is our Milky Way Galaxy surrounded by a halo of hot gas? ... Since NGC 4631 is similar to the Milky Way , this observation indicates that our own Galaxy is indeed surrounded by a halo of hot X-ray emitting gas, although we are too close to clearly differentiate it from more nearby extended X-ray sources. The clusters of massive stars probably heat the halo gas. ... About APOD | ...

... Not only can the Sun turn night to day, it can transform obscure 1950s jingles into 1990s alternative-rock hits. ... The sun is a mass of incandescent gas, . ... Studying the Sun can tie together subjects across the curriculum. ... Sunspots and prominences--the tongues of hot plasma which shoot off the Sun's surface and arch gracefully back, following the invisible tethers of magnetic field lines--are just two examples of solar volatility. ... The black dots will be easy to see. ...

This is a study of the interstellar matter associated with the Pleiades star cluster. ... Since that time, the project has been extended to include more thorough tests of dust scattering models, more detailed analyses of the gas kinematics, and power spectrum studies of the multiscale structure of the nebulosity. ...

... Видимо, самым популярным предположением о состоянии газа или газообразного вещества, является модель идеального газа. (иногда добавляют одноатомного газа, но в нашем рассмотрении это несущественно). ... Поэтому иногда имеет смысл поступить наоборот - определить сам идеальный газ как такой газ, который подчиняется уравнению состояния идеального газа! В действительности, многие вещества в газообразном состоянии проявляют свойства, близкие к предсказываемым для идеальных газов. ...
