During night time, we can see the stars of the Milky Way Galaxy if we look up in the sky. We can also have a choice to view the diary band of the Milky Way, when it is too dark at night and far from citylights. Besides our Milky Way galaxy, there are millions and millions of ...
Local Group, in astronomy, the group of more than 20 galaxies to which the Milky Way Galaxy belongs. About half are elliptical galaxies, with the remainder being of the spiral or irregular type. As in other clusters of galaxies, members are probably kept
O n any clear night, if you are well away from sources of artificial light, you will see a misty band of radiance that girdles the sky, crossing constellations such as Cassiopeia, Cygnus and Sagittarius. We call this band the Milky Way . When Galileo first turned his telescopes to the ...
CfA astronomers Blakesley Burkhart and John Forbes and two colleagues have developed a new unified model for galaxy discs that explains these phenomena, and some others besides. The scientists show that the correlation ofstar formationrate with gas motion is not caused by these motions but rather ...
Besides the many observations of lensed galaxies and quasars, the feasibility of observing strong gravitational lensing of explosive transients in the distant universe has only been demonstrated in recent years (refs.3,4,5and references therein). PS1-10afx was the first highly magnified type Ia su...
Besides the Sun ProximaCentauri (半人马比邻座星) isthe closest star at 4.2 light years away: Some of the brightest stars are moredistant Rigel (参宿七) in the constellation Orion (猎户星座) is the seventh brightest star inthe sky but is 900...
(Moreover, such systems are preferentially discovered in deep galaxy surveys precisely because they are so luminous.) But galaxies in the distant cosmos are too remote to detect spatial signatures like tidal arms (at least with current telescopes). It is possible that other processes besides ...
The uncertain metallicity dependence of RDWs adds to a hotly debated question: what is the total mass lost throughout the stellar lifetime, and what is the main driving mechanism? Besides RDWs, pulsation- and rotation-driven outflows, evolution and/or mass exchange in binary systems, and erup...
(α ≳ 2.2). In comparison with the estimated spectrum for Coma-like clusters6, our gamma-ray flux is a little higher. In both studies6,41, besides the oversimplified ICM magnetic-field and density distributions, assumed to have radial profiles, they did not account for the ...
