Located near the Orion Nebula, these nebulosities have catalog designations HH1 and HH2 for their discoverers astronomers George Herbig and Guillermo Haro. The nascent star which produced the jets is in the middle, hidden by a cloud of obscuring dust.

1995年6月6日 · Pair of Jets from a Young Star (HH1/HH2) This NASA Hubble Space Telescope image reveals new secrets of star birth as revealed in a pair of eerie spectacular jet of gas the star has ejected by a young star.

1995年6月6日 · HH-1/ HH-2 lies 1,500 light-years away in the constellation Orion. This NASA Hubble Space Telescope image reveals new secrets of star birth as revealed in a pair of eerie spectacular jet of gas the star has ejected by a young star. [top] - Tip to tip, this jet spans slightly more than a light-year. The fountainhead of this structure – the young...

2013年11月28日 · Cataloged as Herbig-Haro (HH) objects, named for astronomers George Herbig and Guillermo Haro, the shocks look like red gashes in this scene that includes HH1 and HH2 just below NGC 1999. The stellar jets push through the surrounding material at speeds of hundreds of kilometers per second .

We present continuum and Hα imaging polarimetry of the Herbig-Haro objects HH1 and HH2, the faint nebulosity which surrounds them, and nearby stars. We also discuss IRAS observations of the area.

2022年3月9日 · 除了少量的健康状态（SOH）通道外，代码的第一个字母代表采样率和传感器带宽的组合，例如. 第二个字母表示传感器类型，例如. 第三个字母表示传感器方向或处理阶段。 Z（单组分垂直传感器，或用于测量高度的压力传感器）。

Referred to as HH1, HH2, HH3, HH4, HH5, and HH6 these haplotypes are believed to cause embryonic or fetal death when present in homozygous form, i.e., the offspring inherits the haplotype from both the sire and dam. In a herd, this would appear as if a cow did not conceive, resulting in greater days open and lower conception rates.

Recessive haplotypes that affect fertility and stillbirth in dairy cattle (haplotypes BH1–BH2, HH1–HH5, and JH1–JH2 were described in detail by VanRaden et al. (2011, 2013, 2014). A recessive mutation that causes embryo death (haplotype HH6) …

ガスの噴出速度が秒速数100kmにも及ぶ，非常に活動的な天体です。これは初めて発見されたハービック・ハロー天体で，HH1, HH2という番号が与えられています。

2023年12月14日 · 随着基因组检测技术发展，大量基因组数据分析显示，在荷斯坦牛群中存在一些频率较高但是从未纯合的单倍型，一旦纯合就会造成胚胎早期死亡或者初生犊牛死亡，其中包括荷斯坦牛遗传缺陷单倍型hh1、hh2、hh3(holstein haplotype；vanraden et al.,2011)，hh4(fritz et …
