On January 29 in 1999 Galaxy NGC 2787 Galaxy NGC 2787 is located 24 million light-years from Earth in the constellation Ursa Major. Arms of dark dust encircle the galaxy's bright center. The points of light scattered around the galaxy are huge collections of old stars known as globuar clusters.
About This Image Tightly wound, almost concentric, arms of dark dust encircle the bright nucleus of galaxy NGC 2787 in this NASA Hubble Space Telescope image created by the Hubble Heritage Team.
In astronomer Edwin Hubble's galaxy classification scheme, NGC 2787 is classified as an SB0, a barred lenticular galaxy. These lens-shaped galaxies show little or no evidence of the grand spiral arms that occur in their more photogenic cousins, though NGC 2787 does sport a faint bar, not apparent in this image.
NGC 2787's seemingly bland qualities are, however, just what the doctor ordered for astronomer Marcella Carollo's investigation. Dr. Carollo (Swiss Federal Institute of Technology, Zurich) and team used Hubble to look at the center of these galaxies for clues about the process of galaxy formation including the role of galaxy
collisions and central black holes. Also visible in the Heritage image are about a dozen globular clusters hovering around NGC 2787. What appear to be stars are, in fact, gravitationally bound families of 100,000's of ancient stars orbiting the center of NGC 2787.
NGC 2787 lies roughly 24 million light-years (7.4 megaparsecs) from Earth in the constellation Ursa Major. Data was collected with the Wide Field Planetary Camera 2 in January 1999. This Heritage image was made by combining light from blue, green and infrared filters from the 1999 dataset.

哈勃遺產團隊製作的這張NASA哈勃太空望遠鏡影像顯示，緊緊纏繞的幾乎是同心的深色塵埃臂環繞著星系NGC 2787的明亮核。
在天文學家埃德溫·哈勃（Edwin Hubble）的星系分類方案中，NGC 2787被歸類為SB0，即禁止的雙凸透鏡星系。這些透鏡狀的星係幾乎沒有或沒有證據表明它們的上相較近的表親中出現了巨大的旋臂，儘管NGC 2787確實帶有微弱的條形，在此圖像中不明顯。
然而，NGC 2787的貌似平淡無奇的品質正是醫生命令天文學家Marcella Carollo進行調查的目的。卡羅洛博士（蘇黎世瑞士聯邦理工學院）及其團隊使用哈勃望遠鏡觀察了這些星系的中心，以尋找有關星系形成過程的線索，包括星系碰撞和中心黑洞的作用。
NGC 2787距大熊座星座約2400萬光年（7.4兆帕）。數據是在1999年1月通過“廣角行星相機2”收集的。該遺產圖像是通過組合來自1999年數據集中的藍色，綠色和紅外濾光片的光而製成的。
