Astronotes Armagh Planetarium's Stellar Blog! ... Universe . ... About four centuries ago, a tiny white dwarf star about the same diameter as Earth, but with a mass equivalent to the Sun, swung in a tight orbit about some larger star. The white dwarfтАЩs intense gravity tore material from its more massive companion. ... The quantity of mass in the universe is constant since the universe started its last self-replication, since its last singularity, its last pre-big bang re-birth conception. ...

Then we rotate (x',y',z') by an angle ? around the x' axis, using the same formulas but with (y',z', ?) in place of (x,y, ?) ... Knowing its semi-major axis a, eccentricity e and mean anomaly M, one can derive its true anomaly f (using appropriate formulas, not given in #12a) and from it the radial distance r . ...

Proceedings of the Particle Physics and Early Universe Conference (PPEUC). For this paper: postscript PPEUC CMB index 1 Introduction .. ... A new statistic is discussed, designed to detect isolated coherent step-like discontinuities produced by cosmic strings present at late times. ... The statistical variable considered is the Sample Mean Difference (SMD) between large neighbouring sectors of CMB maps, separated by straight lines in two dimensional maps and points in one dimensional maps. ...

A complete set of schematics, PCB artwork, drill templates is in the pub/ntp/gadget.tar.Z file on ftp.udel.edu. ... One of these converts a TTL positive edge into a fixed- width pulse at EIA levels and is for use with a timecode receiver or oscillator including a TTL PPS output. ... See the schematic diagram gadget.s01 for reference. ...

... For us to see them from such great distances, quasars must be producing enormous energy -- they are about 1000 times brighter than an average galaxy! ... One of their choices for the energy source of quasars was a black hole. ... On the one hand, it may seem difficult to think that mere friction between bits of matter could account for the energy of a quasar, but, on the other hand, gravity is unimaginably strong near a black hole. ... How does matter actually rush towards the black hole? ...
