Hanny's Voorwerp, Dutch for "Hanny's Object", is enormous, about the size of our own Milky Way Galaxy. Glowing strongly in the greenish light produced by ionized oxygen atoms, the mysterious voorwerp is below spiral galaxy IC 2497 in this view from the Hubble Space Telescope.

NGC 2174: звёзды и горы NGC 2174: Stars Versus Mountains

It's stars versus gas mountains in NGC 2174 and the stars are winning. More precisely, the energetic light and winds from massive newly formed stars are evaporating and dispersing the dark stellar nurseries in which they formed.

Радужные облака над трассой Вершина мира Iridescent Clouds from the Top of the World Highway

Like a ship plowing through cosmic seas, runaway star Zeta Ophiuchi produces the arcing interstellar bow wave or bow shock seen in this stunning infrared portrait from the WISE spacecraft. In the false-color view...

Шесть миров системы Кеплер-11 Six Worlds for Kepler 11

Six worlds orbit Kepler-11, a sunlike star 2,000 light-years distant in the constellation Cygnus. The new discovery, based on data from NASA's planet hunting Kepler spacecraft, makes the Kepler-11 system the fullest exoplanetary system known.

Луна и Венера над Швейцарией Moon and Venus over Switzerland

Sometimes a morning sky can be a combination of serene and surreal. Such a sky perhaps existed before sunrise this past Sunday as viewed from a snowy slope in eastern Switzerland. Quiet clouds blanket the above scene, lit from beneath by lights from the village of TrЭbbach.

Степени десятки Powers of Ten

How different does the universe look on small, medium, and large scales? The most famous short science film of its generation gives breathtaking comparisons. That film, Powers of Ten, originally created in the 1960s, has now been officially posted to YouTube and embedded above.
