Спиральная галактика NGC 253 Spiral Galaxy NGC 253

A camera with over 67 million pixels (digital picture elements) was used to record this stunning image of spiral galaxy NGC 253. Known as the Wide Field Imager (WFI), the camera is the latest instrument to be installed at the European Southern Observatory's 2.2 meter telescope in La Silla, Chile.

Возможные планеты и инфракрасная пыль Possible Planets And Infrared Dust

These near-infrared Hubble images of dust surrounding young stars offer the latest tantalizing evidence for planets beyond our Solar System. At left, the dark gap seen in the dust disk is reminiscent of a similar large gap in Saturn's rings believed to be sculpted by orbiting moons.

Телескоп и молния Telescope with Lightning

Telescopes are not very useful during lightning storms. Nevertheless, with lightning illuminating a dark landscape, the picturesque dome of the famous Kitt Peak 2.1-meter Telescope makes for a dramatic photograph. A passing car created the red and yellow streaks visible in the foreground.

Национальная обсерватория Китт Пик Kitt Peak National Observatory

At the top of Kitt Peak Mountain near Tucson, Arizona lies one of the world's great collections of telescopes. As pictured, in the dome at the far left lies the 3.5-meter WIYN Telescope, famous recently for tracking distant supernovae.

NGC 1818: молодое шаровое скопление NGC 1818: A Young Globular Cluster

Globular clusters once ruled the Milky Way. Back in the old days, back when our Galaxy first formed, perhaps thousands of globular clusters roamed our Galaxy. Today, there are perhaps 200 left. Many globular clusters were destroyed over the eons by repeated fateful encounters with each other or the Galactic center.

Спиральные вихри на планете Земля Spiral Eddies On Planet Earth

Can you identify this wispy stellar nebula? How many light-years from Earth did you say? Resembling a twisting cloud of gas and dust between the stars this swirling form is actually close by - a spiral eddy formed near the North Atlantic Gulf Stream off the East coast of the U. S.

Отражения Ориона Reflections Of Orion

The Orion Nebula and its surroundings present skygazers with a wondrous jumble of newborn stars, gas, and dust. Emission nebulae - glowing energized clouds of gas, and reflection nebulae - dust clouds shining by reflected starlight, abound at this photogenic cosmic location a mere 1,500 light-years or so away.

Рефрактор мемориальной обсерватории им. Кросбай Рэмсея Crosby Ramsey Memorial Observatory Refractor

The Massachusetts-based firm of Alvan Clark and Sons became famous for making telescope optics near the end of the last century. Near the end of this century, major astronomical observatories still boast of telescopes...

Рой звезд в Стрельце Sagittarius Star Cloud

Stars come in all different colors. The color of a star indicates its surface temperature, an important property used to assign each star a spectral type. Most stars in the above Sagittarius Star Cloud are orange or red and relatively faint, as our Sun would appear.

Ветер на Марсе The Wind on Mars

Wind erosion has been discovered on Mars. Pictures of regions surrounding the north polar cap show sand dunes covered in frost. In places, however, this frost has been eroded to uncover the dark sand underneath.
