Луна и Венера над Женевой The Moon and Venus Over Geneva
19.06.2002

The Moon, fresh from a biting encounter with the Sun last week, appeared next to threaten Venus. The waxing Moon appeared to glide right past, however, just a few degrees away. Venus, of course, is much further away from the Earth than the Moon, so the passing was really just an angular illusion.


IC 4406: "квадратная" туманность IC 4406: A Seemingly Square Nebula
18.06.2002

How can a round star make a square nebula? This conundrum comes to light when studying planetary nebulae like IC 4406. Evidence indicates that IC 4406 is likely a hollow cylinder, with its square appearance the result of our vantage point in viewing the cylinder from the side.


NGC 4697: рентгеновское излучение из эллиптической галактики NGC 4697: X Rays from an Elliptical Galaxy
17.06.2002

The many bright, point-like sources in this Chandra Observatory x-ray image lie within NGC 4697, an elliptical galaxy some 40 million light-years away towards Virgo. Like other normal elliptical galaxies, NGC 4697 is a spherical ensemble of mainly older, fainter, low mass stars, with little star forming gas and dust compared to spiral galaxies.


У Юпитера выявлены кольца Jupiters Rings Revealed
16.06.2002

Why does Jupiter have rings? Jupiter's rings were discovered in 1979 by the passing Voyager 1 spacecraft, but their origin was a mystery. Data from the Galileo spacecraft currently orbiting Jupiter later confirmed that these rings were created by meteoroid impacts on small nearby moons.


MyCn18: туманность в форме песочных часов MyCn18: An Hourglass Nebula
15.06.2002

The sands of time are running out for the central star of this hourglass-shaped planetary nebula. With its nuclear fuel exhausted, this brief, spectacular, closing phase of a Sun-like star's life occurs as its outer layers are ejected - its core becoming a cooling, fading white dwarf.


55 Рака: открыта новая планета 55 Cancri: Familiar Planet Discovered
14.06.2002

Is our Solar System unique? The discovery of a Jupiter-like planet in a Jupiter-like orbit around nearby Sun-like star 55 Cancri, announced yesterday, gives a new indication that planetary systems similar to our Solar System likely exist elsewhere. The planet, discovered by G.


Область туманности Тарантул The Tarantula Zone
13.06.2002

The Tarantula Nebula is more than 1,000 light-years across - a giant emission nebula within our neighboring galaxy the Large Magellanic Cloud. Inside this cosmic arachnid lies a central young cluster of massive stars, cataloged as R136, whose intense radiation and strong winds have helped energize the nebular glow and shape the spidery filaments.


Частное затмение Солнца в проливе Золотые Ворота A Partial Eclipse Over the Golden Gate Bridge
12.06.2002

Part of the Sun disappeared behind the Moon earlier this week. Previously, the waning Moon was best visible from all places on Earth during the early morning hours because it trailed the Sun. As the Moon orbited the Earth, however, it caught up to the Sun and passed it on the sky.


Внутри Туманности Орла Inside the Eagle Nebula
11.06.2002

From afar, the whole thing looks like an Eagle. A closer look of the Eagle Nebula, however, shows the bright region is actually a window into the center of a larger dark shell of dust. Through this window, a brightly-lit workshop appears where a whole open cluster of stars is being formed.


Кольцеобразное затмение: огненное кольцо Annular Eclipse: The Ring of Fire
10.06.2002

Today, a few lucky people will see a "ring of fire." That's a name for the central view of an annular eclipse of the Sun by the Moon. At the peak of this...
