NASA-星光,星光明亮🌟在大麦哲拉中,一个密集的球状星团位于距地球约157,000光年的地方。
案例简介:星光,星光灿烂🌟一个密集的球状星团位于 @ NASAHubble捕获的大麦哲伦星云 (LMC) 中,距地球约157,000光年。球状星团是非常稳定的,由数千甚至数百万颗恒星紧密结合的星团。它们的稳定性意味着它们可以持续很长时间,因此经常研究球状星团以研究潜在的非常古老的恒星种群。研究2017年估计,这个球状星团可能在116亿岁左右。尽管这只比宇宙本身年轻几十亿年,但这个球状星团是他们样本中最年轻的星团。在同一工作中研究的所有LMC球状星团都被发现年龄较大,其中四个年龄超过130亿岁。这个球状星团非常有趣,因为它拥有高度集中的恒星群。从围绕球状星团中心的一颗恒星运行的行星的居民的角度来看,夜空看起来会大不相同: 在比我们拥挤数千倍的恒星环境中,天空似乎充满了恒星。图片说明: 密集的星团.它是最明亮和最拥挤的中心,那里的星星大多是冷白色。向边缘移动,恒星变得更加分散和偏红,直到到达星团的明显 “边缘”。在那个边缘之外,仍然有许多星星,更加混乱,在黑色背景上看到。一些恒星似乎在星团的前面。图片来源: ESA/Hubble & NASA,A.Sarajedini # NASA # 太空 # 星星 # 星系 # 天文学 # 恒星 # 天体摄影

案例简介:Star light, star bright 🌟A densely-packed globular cluster lies about 157,000 light-years from Earth in the Large Magellanic Cloud (LMC) captured by @NASAHubble. Globular clusters are very stable, tightly bound clusters of thousands or even millions of stars. Their stability means that they can last a long time, and therefore globular clusters are often studied to investigate potentially very old stellar populations. Research from 2017 estimates that this globular cluster probably clocks in at around 11.6 billion years old. Even though this is only a couple billion years younger than the universe itself – this globular is the youngest cluster in their sample. All of the LMC globular clusters studied in the same work were found to be older, with four of them over 13 billion years old. This globular cluster is as interesting as it is beautiful with its highly concentrated population of stars. The night sky would look very different from the perspective of an inhabitant of a planet orbiting one of the stars in a globular cluster’s center: the sky would appear to be stuffed full of stars, in a stellar environment that is thousands of times more crowded than our own.Image Description: A dense cluster of stars. It is brightest and most crowded in the center, where the stars are mostly a cool white color. Moving out towards the edges the stars become more spread out and reddish until a noticeable ‘edge’ to the cluster is reached. Beyond that edge there are still many stars, more disorganized and seen on a black background. Some stars appear to be in front of the cluster.Credit: ESA/Hubble & NASA, A.
