Is there a road to the stars? Possibly there are many, but the physical road pictured above leads up to the top of a dormant volcano that is a premier spot on planet Earth for observing stars and astronomical phenomena.

Тонкие кольца Сатурна в поляризованном свете Thin Rings Around Polarized Saturn

How thin are the rings of Saturn? Brightness measurements from different angles have shown Saturn's rings to be about one kilometer thick, making them many times thinner, in relative proportion, than a razor blade. This thinness sometimes appears in dramatic fashion during an image taken nearly along the ring plane.

If you could see one of the robot rovers currently rolling across Mars, what would it look like? To gain this perspective useful in planning explorations, the above synthetic image was produced digitally. Above...

Вид на Рею с  высоты 620 километров 620 Kilometers Above Rhea

What does the surface of Saturn's moon Rhea look like? To help find out, the robot Cassini spacecraft currently orbiting Saturn was directed to fly right past the second largest moon of the gas giant planet late last month.

30 Золотой Рыбы: зона Тарантула 30 Doradus: The Tarantula Zone

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 massivestars, cataloged as R136, whose intense radiation and strong winds have helped energize the nebular glow and shape the spidery filaments.
