가까운 나선 은하 NGC 6946는 현저한 사유 없이 별의 형성의 엄청난 폭발을 경험하고 있습니다. 대부분의 경우에 나선들은 또 다른 성운과 상호 작용할 때 밝아집니다, 그러나 NGC 6946는 공간에 상대적으로 격리된 것처럼 보입니다. 케페우스 자리의 별자리쪽으로 단지 떨어져서 1000만 광년의 위치를 정하였습니다, 이 아름다운 판자의 이음새 나선은 대략 20,000 광년정도 자벌레처럼 나아갑니다. NGC 6946의 센터는 핵 starburst 그 자체에 집 입니다, 그리고 그림과 같은 어두운 먼지는 빛난 푸른별들,…

The Cone Nebula is an intense region of starbirth, a chaotic place where new stars are born inside a natal cloud and recently born, hot and massive stars buffet the nursery with intense radiation. The nebula of gas and dust, lit by surrounding stars, is about 2,500 light-years away This image was m…
Credit: ESA, NASA, Descent Imager/Spectral Radiometer Team (LPL) Methane rain, evaporating lakes, flowing rivers, and water ice-volcanoes all likely exist on Saturn's moon Titan, according to preliminary analyses of recent images taken by the successful Huygen's lander. A snaking and branching riv…
A satellite galaxy of the Milky Way, the Small Magellanic Cloud (SMC) is a wonder of the southern sky, a mere 210,000 light-years distant in the constellation Tucana. Found among the SMC's clusters and nebulae NGC 346 is a star forming region about 200 light-years across, pictured above by the Hubbl…
This color view from Titan gazes across a suddenly familiar but distant landscape on Saturn's largest moon. The scene was recorded by ESA's Huygens probe after a 2 1/2 hour descent through a thick atmosphere of nitrogen laced with methane. Bathed in an eerie orange light at ground level, rocks strew…
Old photographs show no evidence of the above nebula. In 1992, a white dwarf star toward the constellation of Cygnus blew off its outer layers in a classical nova explosion: an event called Nova Cygni 1992. Light flooded the local interstellar neighborhood, illuminated this existing gas cloud, excit…
Big, beautiful barred spiral galaxy NGC 1300 lies some 70 million light-years away on the banks of the constellation Eridanus. This Hubble Space Telescope composite view of the gorgeous island universe was released at this week's meeting of the American Astronomical Society as one of the largest Hub…

What creates the cosmic dust sculptures in the Rosette Nebula? Noted for the common beauty of its overall shape, parts of the Rosette Nebula, also known as NGC 2244, show beauty even when viewed up close. Visible above are globules of dark dust and gas that are slowly being eroded away by the energe…
