First Confirmed Heartbeat of a Black Hole Is Still Beating
The first confirmed heartbeat of a supermassive black hole is still going strong more than ten years after first being observed.
首次被证实的超大质量黑洞的心跳,在十多年后第一次被观测到,依旧很强烈。
X-ray satellite observations spotted the repeated beat after its signal had been blocked by our Sun for a number of years.
x射线卫星观测发现,在它的信号被太阳阻挡了数年之后,它仍会重复跳动。
Astronomers say this is the most long-lived heartbeat ever seen in a black hole and tells us more about the size and structure close to its event horizon — the space around a black hole from which nothing, including light, can escape.
天文学家说,这是迄今为止在黑洞中发现的最持久的心跳,并告诉我们更多关于黑洞视界附近的大小和结构的信息。视界--是黑洞周围的空间,包括光在内,任何东西都不能从黑洞那里逃脱。
每次看天文学的相关文章,都能开阔心智。在天文学的概念里,日常理解的时间空间都没有了意义,什么金钱爱情社会地位、什么国际问题、什么疫情、什么经济萧条都成了尘埃。
动则上亿光年的距离,估计跳一次,一个地球就没了,再跳一次,就又出了一个太阳了。
是滴,宇宙尺度,我们如此渺小。
不如意时,请仰望星空,那里会有你的答案~
