... Over the last decade the uninterrupted, high-resolution coverage of the Sun both from the excellent range of telescopes aboard many spacecraft and from ground-based instruments has led to a wealth of observations of small-scale dynamic events observed from the chromosphere to the transition region and corona. ... SoHO observations have further characterized many transient features, such as bi-directional jets, blinkers, coronal jets, and bright points. ...

... 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. ...

... Dark energy is believed to be a component of the Universe whose repulsive gravity is presently accelerating the expansion of the Universe.€а Although it comprises the bulk of the mass-energy of the Universe, its nature is not well understood.€а €аAlbert Einstein originally suggested its existence about 80 years ago. A supernova is the explosive death of a star, which unleashes a burst of light through the cosmos. ... This website is a gift from Nancy Riess . ...

Microsymposium 34, MS047, 2001 SOME PROBLEMS OF THE EVOLUTION OF ASTEROIDS ­ RUBBLE PILE. ... Evidently, we can distinguish two processes: distant interactions, where there is no direct contact between separate fragments, and close contact interactions, where the fragments collide with one another. ... Such a rubble pile with a dust atmosphere differs from a cometary nucleus only in the absence of a volatile gas component, which is usually considered the cause of the appearance of cometary dust. ...

Neutral Hydrogen Absorption Measurements of Four Distant Pulsars . and the Electron Density in the Inner Galaxy . ... Abstract We have used the VLA to measure neutral hydrogen absorption and emission spectra toward four distant, low-latitude pulsars in the inner Galaxy whose spectra have not been previously recorded. ... We use the companion spectra plus all published \HI absorption spectra in the direction of each pulsar to assist in the kinematic determination of pulsar distances. ...

... ESO has released a striking new image of a nearby galaxy that many astronomers think closely resembles our own Milky Way. Though the galaxy is seen edge-on, observations of NGC 4945 suggest that this hive of stars is a spiral galaxy much like our own, with swirling, luminous arms and a bar-shaped central region. ... As NGC 4945 is only about 13 million light-years away in the constellation of Centaurus (the Centaur), a modest telescope is sufficient for skygazers to spot this remarkable galaxy. ...
