Stars can form orbital systems with other astronomical objects, as in planetary systems and star systems with two or more stars. When two such stars orbit closely, their gravitational interaction can significantly impact their evolution. Stars can form part of a much larger gravitationally bound structure, such as a star cluster or a galaxy.
The final fate of the star depends on its mass, with stars of mass greater than about eight times the Sun becoming core collapse supernovae; [101] while smaller stars blow off their outer layers and leave behind the inert core in the form of a white dwarf. The ejection of the outer layers forms a planetary nebula. [102]
In 2016, the International Astronomical Union (IAU) organized a Working Group on Star Names (WGSN) [2] to catalog and standardize proper names for stars. The WGSN's first bulletin, dated July 2016, [3] included a table of 125 stars comprising the first two batches of names approved by the WGSN (on 30 June and 20 July 2016) together with names of stars adopted by the IAU Executive Committee ...
They were grown in 1995 aboard Space Shuttle Columbia. 7. The London Bridge was moved from England to Lake Havasu City, Arizona, in 1968 when Robert P. McCulloch bought it.
No, actually -- even NASA is calling this star the "loneliest" in the universe. "The unusual object, called CX330, was first detected as a source of X-ray light in 2009," according to a NASA news ...
The two stars were known to the Bedouin as "qarna al-hamal", "horns of the ram". [30] It is 59 light-years from Earth. [31] It has a luminosity of 11 L ☉ and its absolute magnitude is 2.1. [29] It is a spectroscopic binary star, one in which the companion star is only known through analysis of the spectra. [32] The spectral class of the ...
CAPE CANAVERAL, Fla. (AP) — The Webb Space Telescope is marking one year of cosmic photographs with one of its best yet: the dramatic close-up of dozens of stars at the moment of birth.. NASA ...
It includes the atmosphere and outer space. It may also be considered a place between the ground and outer space, thus distinct from outer space. In the field of astronomy, the sky is also called the celestial sphere. This is an abstract sphere, concentric to the Earth, on which the Sun, Moon, planets, and stars appear to be drifting.
