NASA-一个小星星团拖着一棵圣诞树。🎄发现了距地球约2,500光年的圣诞树
案例简介:一个小星星团拖着一棵圣诞树。🎄圣诞树星团距离地球约2,500光年,是一群年轻的恒星,大多数大约1到500万岁。(相比之下,我们的太阳已经燃烧了50亿年) 这些恒星发出的x射线是由我们绕轨道运行的 @ NASAChandraXRay天文台拍摄的,并在这里以各种深浅的蓝色和白色描绘。它们被其他望远镜观测到的气体星云所包围,这里以绿色显示,这给这个星团 (正式名称为NGC 2264) 起了令人难忘的绰号。图片说明: 一个绿色气体的三角形,像一棵圣诞树,里面充满了看起来像圣诞节装饰品的蓝色和白色星星。其他恒星和天文现象填补了图像的背景。图片来源: x射线: NASA/CXC/SAO; 光学: T.A.

NASA-一个小星星团拖着一棵圣诞树。🎄发现了距地球约2,500光年的圣诞树
案例简介:A little star cluster hauling a Christmas tree. 🎄Discovered about 2,500 light-years from Earth, the Christmas Tree Cluster is a bundle of young stars, most about 1 to 5 million years old. (For comparison, our Sun has been burning for 5 *billion* years.)These stars give off X-rays that were picked up by our orbiting @NASAChandraXRay observatory, and are depicted here in various shades of blue and white. They’re surrounded by a nebula of gas observed by other telescopes, shown here in green, giving this cluster (officially known as NGC 2264) its memorable nickname.Image description: A triangle of green gas, resembling a Christmas tree, is filled with blue and white stars that look like Christmas ornaments. Other stars and astronomical phenomena fill the background of the image.Credit: X-ray: NASA/CXC/SAO; Optical: T.A.
