A light-year, alternatively spelled light year (ly or lyr [3]), is a unit of length used to express astronomical distances and is equal to exactly 9 460 730 472 580.8 km, which is approximately 5.88 trillion mi.
The optically observed star, LB-1 A, or LS V+22 25, is a B-type star [5] nine times the mass of the Sun and located at least 7,000 light-years (2,100 pc) from Earth. It was found to exhibit radial velocity variations by Chinese astronomers using the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) and the radial-velocity method to search for such wobbly stars.

CD5-CD72 is thought to mediate B cell-B cell interaction. What differentiates B1 cells from other B cells is the variable existence of CD5, CD86, IgM and IgD. [1] B-1 B cells, in the mouse, can be further subdivided into B-1a (CD5 +) and B-1b (CD5 −) subtypes. Unlike B-1a B cells, the B-1b subtype can be generated from precursors in the adult ...

While working with the Mitsubishi company, the British aircraft designer Herbert Smith designed the 2MT1 two-seat biplane torpedo bomber, which flew for the first time in January 1923. [1] It went into Japanese Navy service as the Type 13-1 carrier-borne attack aircraft or B1M1 and was followed by the 2MT2 and 2MT3 variants (also designated B1M1).
