Gaia BH1 (Gaia DR3 4373465352415301632) is a binary system consisting of a G-type main-sequence star and a likely stellar-mass black hole, located about 1,560 light-years (478 pc) away from the Solar System in the constellation of Ophiuchus. [4]
The BH-1 was subsequently rebuilt with a Gnome Omega rotary engine and was finally able to fly with two people aboard. It was known as the BH-1 bis in this configuration, and in 1921 won the Czechoslovak national cross-country rally with an average speed of 125 km/h (78 mph) over the 860 km (536 mi) course. The aircraft was damaged in a crash ...
Ball-and-stick model of the tetrahydroborate anion, [BH 4] −. Borohydride refers to the anion [B H 4] −, which is also called tetrahydridoborate, and its salts. [1] Borohydride or hydroborate is also the term used for compounds containing [BH 4−n X n] −, where n is an integer from 0 to 3, for example cyanoborohydride or cyanotrihydroborate [BH 3 (CN)] − and triethylborohydride or ...

The spectrum of boron monohydride includes a molecular band for the lowest electronic transition X 1 Σ + → A 1 Π with a band head at 433.1 nm (for 0→0) and 437.1 (for 0→1) [3] The spectrum contains P, Q, and R branches. [10] Although BH is a closed shell molecule, it is paramagnetic independent of temperature. [11]

In 1999, the team at LBNL claimed the discovery of long-lived 267 Bh (5 atoms) and 266 Bh (1 atom). [26] Later, both of these were confirmed. [ 27 ] The team at the Paul Scherrer Institute (PSI) in Bern , Switzerland later synthesized 6 atoms of 267 Bh in the first definitive study of the chemistry of bohrium.
