- The first true discovery of extrasolar planets came in 1994 , when radio astronomers discovered worlds around the pulsar psr b1257 + 12 some 980 light-years away in the virgo constellation .
- 第一次真正确定发现太阳系外行星是在1994年，当时射电天文学家在脉冲星psrb1257+12周围发现了系外行星，距地球980光年位于室女座中。
- The pulsar generates a wind of high-energy particles -- seen in the chandra data -- that expands into the surrounding environment , illuminating the material ejected in the supernova explosion .
- 脉冲星产生一种高能量的粒子风--见钱德拉提供数据，这种粒子风膨胀到周围环境，照亮了超新星爆炸中喷射出来的物质。
- It may be the remains of a carbon-rich white dwarf star . But it 's been mostly cannibalized by its pulsar companion , and is now just a shadow of its former self .
- 白矮星已经被它的同伴脉冲星吃好掉了，现在只剩下过去它自己的形状。
- The researchers determined that the precession of the pulsar 's orbital axis advances by 4.77 degrees per year , plus or minus 0.66 degrees .
- 研究者确定，脉冲星的轨道轴进动幅度每年前进4.77度，误差0.66度。
- The temperature in this region appears to vary in a circular pattern around this ring of emission , suggesting that the pulsar may be precessing like a spinning top and sweeping an energizing beam around the gas in rcw 89 .
- 这一区域的温度，在发射环周围表现出不同的循环模式，脉冲星好像一颗陀螺，能量束在rcw-89周围扫过。
- In fact , the first planets ever discovered beyond our solar system were found this way in 1992 , but thanks to the intense radiation coming off a pulsar , there 's no chance life could exist on them .
- 事实上，人类1992年最初发现太阳系外的行星正是通过这样的方式，然而，脉冲星带有极强的辐射，因此不可能有生命存在。
- Specifically , they will be looking to verify that the object is , indeed , acting like a steadily feeding baby black hole and not like an angrily spinning newborn neutron star , or pulsar , which can create a wind of powerful particles that light up gas and debris in space around it with loads of x-rays .
- 具体说来，他们会注意核实天体确实是像稳定摄取食物的新生黑洞那样运行，而不是像一个愤怒地旋转新生中子星或者脉冲星，它们能用大量x射线制造出一股强大的点亮周围气体和空间碎片的粒子流。
- As of 2007 , three extrasolar planets have been confirmed in orbit around this pulsar .
- 直至2007年，在这颗脉冲星周围轨道上已有三颗系外行星被确认。
- The position of the pulsar at the upper right end of the tail is seen by mousing over the image .
- 脉冲星在尾巴末端右上角的位置，可以通过仔细搜寻图像查看到。
- The white source near the center of the image is a dense , rapidly rotating neutron star , or pulsar , all that remains of a core-collapse supernova explosion .
- 图片靠近中心部分的白色光源为一种密度大，急速旋转的中子星，或是脉冲星--都是核心坍缩的超新星爆炸的残留物。
