As the Universe expands, gravity pulls on the Universe, and slows the expansion down over time. As we look to great distances, we are looking back in time. If we can measure how fast the Universe is expanding in the past, and compare it to how fast it is expanding now, we can see the total gravitational effect of all matter in the Universe. Here we plot the distance between two galaxies as a function of time. ... Universes with lots of material . ...

... The storm began quite unexpectedly. The strongest geomagnetic storm for the last seven months began on Earth almost precisely at the same time as the solar eclipse reached its maximal stage, the culmination of which occurred at GMT 02:35 (06:35 Moscow time). ... Oscillations of such amplitude in the magnetic field have not been observed since October, 11th of last year, which is more than seven months ago. ... We can only add that the magnetic storm lasted approximately 9 hours. ...

... A light curve decomposition tool ( LFIT ) developed by Keith Horne and Tom Marsh and its application on HST-data of the eclipsing dwarf nova IP Peg will be presented. ... Our LFIT code decomposes time-resolved spectral data into N components with parameterized light curve shapes, solving for the spectra of each component. ... To apply this algorithm to the HST and UBVRI eclipses of IP Peg, we add an ellipsoidal light curve for the companion star, and a more detailed description of the bright spot. ...

... Since moonshine is really reflected sunlight, the full Moon is on the average slightly brighter in mid-winter, when Earth is closest to the Sun. In addition, the distance of the full Moon also varies, due to the ellipticity ("eccentricity") of the Moon's orbit. On 22 December, 1999, the two effects combined to produce the brightest full Moon of the century. ... This year will be the first full moon to occur on the winter solstice, Dec. 22nd, commonly called the first day of winter. ...

Educator's Guide to Eclipses . ... In a solar eclipse you observe the Sun (using only safe methods, of course). ... In a lunar eclipse you observe the Moon. ... Because of the geometry described below, you can only view a solar eclipse when the Sun is up, and the Moon is nowhere to be seen. ... Eclipses occur when the Sun, Earth and Moon line up. ... In a solar eclipse the Moon passes directly in front of the Sun. ... In a lunar eclipse the Moon moves into Earth's shadow. ...

... The most spectacular view however is from space, where large areas of aurora can be observed simultaneously, even the entire polar cap. ... Such pictures often show a continuous ring of aurora around the polar cap (picture above), caused mostly by electrons leaking out along magnetic field lines, from the plasma sheet of the Earth's magnetic tail. ... Field lines from the auroral oval are believed to lead to the plasma sheet. ... A near-Earth circular polar orbit has many uses. ...
