Today the Sun reaches its southernmost point in planet Earth's sky at 13:37 UT. This celestial event is known as a solstice, marking the beginning of Summer in the Southern Hemisphere and Winter in the North.


Sgr A*: Быстрые звезды вблизи центра Галактики Sgr A: Fast Stars Near the Galactic Center
19.12.2000

Why are these stars moving so fast? Shown above is a time-lapse movie in infrared light detailing how stars in the central light-year of our Galaxy have moved over the past eight years. The yellow mark at the image center represents the location of a peculiar radio source named Sgr A


Полярное сияние на Юпитере крупным планом A Close Up of Aurora on Jupiter
18.12.2000

Jupiter has aurorae. Like Earth, the magnetic field of the gas giant funnels charged particles released from the Sun onto the poles. As these particles strike the atmosphere, electrons are temporarily knocked away from existing gas molecules. Electric force attracts these electrons back. As the electrons recombine to remake neutral molecules, auroral light is emitted.


Скрытые океаны на Ганимеде? Oceans Under Jupiter's Ganymede
17.12.2000

The search for extraterrestrial life came back into our own Solar System last week with the announcement that there may be liquid oceans under the surface of Jupiter's moon Ganymede. Ganymede now joins Callisto and Europa as moons of Jupiter that may harbor seas of liquid water under layers of surface ice.


M2-9: Крылья Туманности Бабочка M2 9: Wings of a Butterfly Nebula
16.12.2000

Are stars better appreciated for their art after they die? Actually, stars usually create their most artistic displays as they die. In the case of low-mass stars like our Sun and M2-9 pictured above


Меркурий: Дега -- кратер с лучевой системой Degas Ray Crater on Mercury
15.12.2000

Like the Earth's Moon, Mercury is scarred with craters testifying to an intense bombardment during the early history of the Solar System. In 1974, the Mariner 10 spacecraft surveyed this innermost planet up close, producing the only detailed images of its tortured surface.


Нейтронная звезда в туманности IC443 IC443's Neutron Star
14.12.2000

Using x-ray data from the orbiting Chandra Observatory along with radio data from the Very Large Array, a team of researchers has discovered evidence for a new example of one of the most bizarre objects known to modern astrophysics -- a neutron star.


След Международной космической станции International Space Station Trail
13.12.2000

Still under construction, the International Space Station is literally becoming one of the brightest, fastest moving stars in the heavens. Despite illuminated clouds and bright light from a nearly full moon (lower left), this...


Планета Земля: ударный кратер Маникуаган Manicouagan Impact Crater on Earth
12.12.2000

The Manicouagan Crater in northern Canada is one of the oldest impact craters known. Formed during a surely tremendous impact about 200 million years ago, the present day terrain supports a 70-kilometer diameter hydroelectric reservoir in the telltale form of an annular lake


Ганимед под неусыпным взором Юпитера Jupiter Eyes Ganymede
11.12.2000

Who keeps an eye on the largest moon in the Solar System? This moon, visible on the lower right, is Ganymede, and the planet it orbits, Jupiter, seems to be keeping a watchful eye, as its Great Red Spot appears serendipitously nearby.
