The Orion Nebula M42 with NGC 1980 on the right (right is south) NGC 1980 (also known as OCL 529, Collinder 72 and The Lost Jewel of Orion [6]) is a young open cluster associated with an emission nebula in the constellation Orion. It was discovered by William Herschel on 31 January 1786. [7]
The Trapezium Cluster is a component of the much larger Orion Nebula cluster, an association of about 2,800 stars within a diameter of 20 light years. [10] The Orion Nebula is in turn surrounded by the much larger Orion molecular cloud complex which is hundreds of light years across, spanning the whole Orion Constellation.
Given the scientific significance of M42, Orion's Sword is a popular spot for stellar and protostellar studies. Using the Hubble Space Telescope , O'dell et al. focused on identifying previously unseen features of the nebula, such as high-ionization shocks, compact sources, and protoplanetary disks . [ 6 ]
The Trapezium or Orion Trapezium Cluster, also known by its Bayer designation of Theta 1 Orionis (θ 1 Orionis), is a tight open cluster of stars in the heart of the Orion Nebula, in the constellation of Orion. It was discovered by Galileo Galilei. On 4 February 1617 he sketched three of the stars (A, C and D), but missed the surrounding ...
The giant molecular cloud Orion A is the most active star-forming region in the local neighbourhood of the Sun. In the last few million years about 3000 young stellar objects were formed in this region, including about 190 protostars and about 2600 pre-main sequence stars. [6]
Oil prices bounced around quite a bit in 2024. They rallied more than 20% at one point -- topping $85 per barrel -- before cooling off toward the end of the year.
The catalogue consists of a diverse range of astronomical objects, from star clusters and nebulae to galaxies. For example, Messier 1 is a supernova remnant , known as the Crab Nebula , and the great spiral Andromeda Galaxy is M31.
The reason may be, at least partly, price. Toledano declined to disclose how much the fragment used for the B/1M cost, but he noted that raw meteorite can sell for more, per gram, than gold.
