... SS433 is a close binary system, one star is a supergiant, a second one is a black hole. ... Even a black hole cannot accept such an enormous mass flux, a supercritical accretion disk appears, all the excess gas glows up to several tens of thousands degrees and is ejected off the disk with enormous velocities. ... SAO researchers have found an evidence of the supercritical accretion onto a black hole in SS433, which follows from a brightness variability of the SS433 disk. ...

Astronotes Armagh Planetarium's Stellar Blog! ... Earth Satellites . ... According to Velikovsky, about 4000 years ago a giant volcano on Jupiter erupted and spewed a vast glob of debris into space, leaving the Great Red Spot behind as a permanent scar. The red hot lump ejected from Jupiter (referred to as a comet by Velikovsky) wandered into the inner Solar System, repeatedly crossing the Earth?s orbit and in fact often passing close to our helpless planet in the following millennia. ...

. The comet Gallea. The comet's core . Gallea is a historical comet. There were 30 approachings to the Sun from the 240 B.C. Returns every 75 - 76 years. In 1986 five space ships met the comet. "Vega-1", "Vega-2" (USSR), "Jotto", "Suisen" and "Sekigake (Japan). The "Vega" spaceships passed the comet's haed in 8000 km from the core, "Jotto" - 600 km. The solid core was registered (16*18 km). The next time this comet will appear in 2061 . Back .
