A number of other somewhat older stars no longer associated with the molecular gas are also part of the complex, most notably the Orion's Belt (Orion OB1b), as well as the dispersed population north of it . Near the head of Orion there is also a population of young stars that is centered on Meissa. The complex is between 1 000 and 1 400 light ...
Barnard's Loop (catalogue designation Sh 2-276) is an emission nebula in the constellation of Orion. It is part of the Orion molecular cloud complex which also contains the dark Horsehead and bright Orion nebulae. The loop takes the form of a large arc centered approximately on the Orion Nebula. The stars within the Orion Nebula are believed to ...
Orion OB1 (Ori OB1) is a contingent group of several dozen hot giant stars of spectral types O and B in Orion. Associated are thousands of lower-mass stars, and a (smaller but significant) number of protostars. It is part of the larger Orion molecular cloud complex. Owing to its relative closeness and complexity it is the most closely studied ...
The Lockheed P-3 Orion is a four-engined, turboprop anti-submarine and maritime surveillance aircraft developed for the United States Navy and introduced in the 1960s. Lockheed based it on the L-188 Electra commercial airliner; it is easily distinguished from the Electra by its distinctive tail stinger or "MAD" boom, used for the magnetic anomaly detection (MAD) of submarines.
Orion's Belt is an asterism in the constellation of Orion.Other names include the Belt of Orion, the Three Kings, and the Three Sisters. [1] The belt consists of three bright and easily identifiable collinear star systems – Alnitak, Alnilam, and Mintaka – nearly equally spaced in a line, spanning an angular size of ~ 140′ (2.3°).
This diagram describes the four-wave mixing interaction between frequencies f 1, f 2, f 3 and f 4. When three frequencies (f 1 , f 2 , and f 3 ) interact in a nonlinear medium, they give rise to a fourth frequency (f 4 ) which is formed by the scattering of the incident photons, producing the fourth photon.
The Lion’s Gate Portal is an astrological term describing the alignment of the sun in Leo, the star Sirius, which is the brightest star as seen from Earth, the constellation Orion’s Belt and ...
Schematic of the Birkeland or Field-Aligned Currents and the ionospheric current systems they connect to, Pedersen and Hall currents. [1]A Birkeland current (also known as field-aligned current, FAC) is a set of electrical currents that flow along geomagnetic field lines connecting the Earth's magnetosphere to the Earth's high latitude ionosphere.
