ʻOumuamua is a small object estimated to be between 100 and 1,000 metres (300 and 3,000 ft) long, with its width and thickness both estimated between 35 and 167 metres (115 and 548 ft). [ 13 ] It has a red color, like objects in the outer Solar System.
Microlensing Observations in Astrophysics (MOA) is a collaborative project between researchers in New Zealand [1] and Japan, [2] led by Professor Yasushi Muraki of Nagoya University. [3] They use microlensing to observe dark matter , extra-solar planets , and stellar atmospheres from the Southern Hemisphere .
0.11+0.21. −0.06 or 0.003 M☉. Mass. 115.2327 or 3.6+2.0. −1.7 MJup. Database references. SIMBAD. data. MOA-2011-BLG-262L is an astronomical object of uncertain nature with an orbiting companion, detected through the gravitational microlensing event MOA-2011-BLG-262 in the constellation Sagittarius.
OGLE-2011-BLG-0462. OGLE-2011-BLG-0462, also known as MOA-2011-BLG-191, is a stellar-mass black hole isolated in interstellar space. OGLE-2011-BLG-0462 lies at a distance of 1,720 parsecs (5,610 light years) in the direction of the galactic bulge in the constellation Sagittarius. The black hole has a mass of about 6.03 M☉. [1]
The nautical mile (nmi) was originally defined as the arc length of a minute of latitude on a spherical Earth, so the actual Earth circumference is very near 21600nmi. A minute of arc is π/10800 of a radian. A second of arc, arcsecond (arcsec), or arc second, denoted by the symbol ″, [ 2 ] is 1/60 of an arcminute, 1/3600 of ...
Crested moa. The crested moa ( Pachyornis australis) is an extinct species of moa. It is one of the 9 known species of moa to have existed. [3] Moa are grouped together with emus, ostriches, kiwi, cassowaries, rheas, and tinamous in the clade Palaeognathae. Some of the species of this group are flightless and lacks a keel on their sternum. [4]
MOA-2009-BLG-387 was a gravitational microlensing event detected by the Microlensing Observations in Astrophysics collaboration on July 24, 2009, which searches and documents chance and brief alignments of stars with other stars or objects; such alignments cause a gravitational lens effect, which bends light and causes distorted, but magnified ...
Mode of action. In pharmacology and biochemistry, mode of action (MoA) describes a functional or anatomical change, resulting from the exposure of a living organism to a substance. [1] In comparison, a mechanism of action (MOA) describes such changes at the molecular level. [2][1]
