2021年10月25日 · The team used this method to detect the exoplanet candidate in a binary system called M51-ULS-1, located in M51. This binary system contains a black hole or neutron star orbiting a companion star with a mass about 20 times that of the Sun.

2020年9月18日 · M51-ULS-1b is the first planet candidate to be found because it produces a full, short-lived eclipse of a bright XRS. M51-ULS-1b has a most probable radius slightly smaller than Saturn. It orbits one of the brightest XRSs in the external galaxy M51, the Whirlpool Galaxy, located 8.6 Megaparsecs from Earth.

2021年7月17日 · m51-uls-1的半径可能达到了25倍太阳半径，质量至少能达到20倍太阳质量。 就在m51-uls-1的10倍半径的轨道上（比地球轨道稍微远一点），科学家发现了第一颗河外行星——m51-uls-1b。根据计算，科学家得出m51-uls-1b的半径大约是木星半径的三分之一（大 …

2020年9月29日 · The planet has been labeled M51-ULS-1b, and is estimated to be slightly smaller than Saturn. It orbits its stars about 10 times the distance from Earth to the sun.

M51-ULS-1b is a giant extragalactic planet candidate orbiting the high-mass X-ray binary M51-ULS-1, located around 23,000,000 (23 million) light years (7,051,832 parsecs) from Earth in the Whirlpool Galaxy (also known as Messier 51).

Detailed information about planet M51-ULS-1 b and its parameters.

2021年10月25日 · The potential world, called M51-ULS-1b, orbits both a massive star and a dead star in the Whirlpool galaxy, about 28 million light-years from Earth. The object’s existence, if confirmed, suggests...

M51-ULS-1b is the first planet candidate discovered when it passed in front of an XRS whose size is comparable to its own.

2020年10月27日 · 通过X射线掩食法在涡状星系RX J1131-1231中发现银河系外行星M51-ULS-1b. 图为首次发现银河系外行星的RX J1131-1231星系的引力透镜图像。 中间的红色圆点是前景星系，这个星系中估计包含有万亿以上的行星。 白点圆点代表了遥远背景天体经过前景星系时的成像。 图片来源：美国俄克拉荷马大学官网. （神秘的地球uux.cn报道）据科技日报：9月25日，在预印本网站arXiv.org上刊载的一篇论文引发关注，美国哈佛大学史密森尼天体物理中心的天文学家罗 …

2021年11月11日 · The potential first extragalactic planet M51-ULS-1b was found after Di Stefano and team suspected that a planet somewhere in the Whirlpool Galaxy, otherwise known as M51, was responsible for the “eclipsing” of an X-ray binary star.
