Nova 1998 2 in M31 this image of the second Nova in M31 in 1998, was made from 38 exposures of 45 seconds integration time. It was made at September 21, 22h 20m UT. Telescope was a CG11 at f/6.3, no filters were used. The long list of processing steps caused the artefacts at the overexposed center of the galaxy and in many of the brighter stars. During the exposures thin clouds covered the sky but the CCD cuts through them, allowing me to obtain this result. ...

Dense regions reach a maximum size and then fall back into a bound object like a cluster of galaxies. Once the cluster is formed, its physical size remains essentially constant. The space-time diagram below . shows a dense region in blue on the left. ... The galaxies in the blue region are accelerating more just because the region is denser and therefore has higher gravitational forces. ... Tutorial : Part 1 | Part 2 | ...

Next: Imaging by an Optimizing Method . ... A big advantage of this numerical integrator is its stability: the error in the semi-major axis and the eccentricity depends only on the step size and does not grow with an increasing number of time steps. ... As the integration time increases, the numerical results become more contaminated by various errors. ... A new symplectic integrator produces no secular truncation errors in the actions of a Hamiltonian system. ...

Asteroid 2055 YU55 passes close by Earth; how close did it get? ... As Elizabeth Flock reported: An asteroid the size of an aircraft carrier missed Earth by only 200,000 miles as it flew by Tuesday night the closest an asteroid has been to Earth in 200 years Asteroid 2005 YU55, as it has been dubbed, streaked by at about 30,000 mph, but some scientists and lucky amateur astronomers caught a glimpse in their telescopes, where they saw strange structures on the asteroid\u2019s dark-colored surface. ...

... Acceleration of particles in the vicinity of a massive black hole We propose a two-step mechanism for charged particle acceleration in the magnetosphere of a massive black hole surrounded by an accretion disk. Particles first gain energy by stochastic process during the accretion phase. It is shown that effective proton acceleration up to energies eV is possible in the turbulent magnetized accretion disk. ...

The results of a search for ultrarapid variability of galactic water maser sources at the wavelength 1.35 cm on a timescale of several minutes to 1 h are reported. A special observational technique was developed. ... Among those, several sources that have shown such variability were found. ... Clear evidence for such a variability type was found in at least two sources: W49N and W33B. Variability of this kind displays itself only in certain states of the water masers. ...
