This striking view of the Cartwheel Galaxy is a composite of GALEX (blue), Hubble Space Telescope (green), Spitzer Space Telescope (red) and Chandra X-ray Observatory (purple) images. The outer ring, which could encircle our Milky Way Galaxy, appears blue and violet. Pink clumps along the outer ring show X-ray and ultraviolet sources occuring together. ... The Cartwheel's inner ring and nucleus appear yellow-orange because they emit primarily at visible and infrared wavelengths. ...

The First Law (1): Energy is Conserved in a closed system: . ... We usually consider work and heat flow as the two kinds of energy . The Second Law (2): The Law of Entropy: . ... The amount of disorder increases . ... You can not go from a disordered system to an ordered system without inputting more energy (this is the most important attribute of the second law) . ... In no way can we recover work of that this disordered system without putting energy into the system. ... More on Thermodynamics . ...

... An important element of the VO is a data model that can unambiguously represent the relationships between data values and physical properties. ... The Mapping component provides the translation from pixel elements to volumes in the phase space. ... This logical organization is framed by the Index Set , which specifies the indexes or labels that identify the individual data cells. ... This object uses a different Index Set and correspondingly different mappings to access the same data. ...

... April 13, 1999 . The Case of the Missing Supernova . ... About 700 years ago, light from a tremendous explosion reached Earth that should have appeared almost as bright as a full Moon. The bright spot should have lasted for weeks, yet no notation of such an occurrence has been found in historical records. The mystery was uncovered by Wan Chen and Neil Gehrels ( NASA/GSFC ) when studying the source of radioactive elements toward the Vela supernova remnant . ... About APOD > . ...

Underdetermined sets is a new type of data structures (terms) developed in Actor Prolog . ... The point is that an underdetermined set can include some indefinite rest (a tail) like a list in usual Prolog . At the same time, the order of elements of an underdetermined set can be arbitrary one and it does not affect results of unification of underdetermined sets. Moreover, Actor Prolog guarantees that a rest of an underdetermined set never contains elements that are explicitly given in the set. ...
