探测来自天王星的X射线

Astronomers have detected X-rays from Uranus for the first time, using NASA’s Chandra X-ray Observatory, as shown in this image from March 2021. This result may help scientists learn more about this enigmatic ice giant planet in our solar system. Uranus is the seventh planet from the Sun and has two

在新的模拟中,黑洞的吸积盘发出光芒

Astronomers continue to develop computer simulations to help future observatories better home in on black holes, the most elusive inhabitants of the universe. Though black holes likely exist abundantly in the universe, they are notoriously hard to see. Scientists did not capture the first radio imag

哈勃拍摄到一个迷人的螺旋星系

This image shows the spiral galaxy NGC 5037, in the constellation of Virgo. First documented by William Herschel in 1785, the galaxy lies about 150 million light-years away from Earth. Despite this distance, we can see the delicate structures of gas and dust within the galaxy in extraordinary detail

磁化线编织出壮观的银河系挂毯

过热的气体和磁场在银河系的中心编织着能量的织锦。这幅新的宇宙杰作的新图像是由美国宇航局钱德拉x射线天文台和南非的MeerKAT射电望远镜的巨大数据拼接而成的。 银河系中心的新全景图是建立在之前钱德拉和其他望远镜的观测基础上的。与以前的成像活动相比,这个最新版本将钱德拉的高能视野扩展到了银河系平面的上方和下方,也就是银河系大多数恒星所在的圆盘。在我们的主图中,来自钱德拉的X射线显示为橙色、绿色、蓝色和紫色,显示不同的X射线能量,而来自MeerKAT的无线电数据则显示为淡紫色和灰色。图片中的主要特征以标注的方式显示。 有一条线特别引人注意,因为它的X射线和无线电发射交织在一起。它垂直于银河系的平面
