The Milky Way is approximately 890 billion to 1.54 trillion times the mass of the Sun in total (8.9 × 10 11 to 1.54 × 10 12 solar masses), [7][8][9] although stars and planets make up only a small part of this. Estimates of the mass of the Milky Way vary, depending upon the method and data used.
Earth's surface is the boundary between the atmosphere, and the solid Earth and oceans. Defined in this way, it has an area of about 510 million km 2 (197 million sq mi). [12] Earth can be divided into two hemispheres: by latitude into the polar Northern and Southern hemispheres; or by longitude into the continental Eastern and Western hemispheres.
Orion Arm. The Orion Arm, also known as the Orion–Cygnus Arm, is a minor spiral arm within the Milky Way Galaxy spanning 3,500 light-years (1,100 parsecs) in width and extending roughly 20,000 light-years (6,100 parsecs) in length. [2] This galactic structure encompasses the Solar System, including Earth.
Milky Way subgroup: 840,500 pc 2.59×10 19: 19.41: The Milky Way and those satellite dwarf galaxies gravitationally bound to it. Examples include the Sagittarius Dwarf, the Ursa Minor Dwarf and the Canis Major Dwarf. Cited distance is the orbital diameter of the Leo T Dwarf galaxy, the most distant galaxy in the Milky Way subgroup. Currently 59 ...
The Milky Way is brighter in the Southern Hemisphere than in the North. (Photo taken at La Silla Observatory) [2]. The fact that the sky is not completely dark at night, even in the absence of moonlight and city lights, can be easily observed, since if the sky were absolutely dark, one would not be able to see the silhouette of an object against the sky.
A constellation is an area on the celestial sphere in which a group of visible stars forms a perceived pattern or outline, typically representing an animal, mythological subject, or inanimate object. [1] The first constellations likely go back to prehistory. People used them to relate stories of their beliefs, experiences, creation, and mythology.
A nebula (Latin for 'cloud, fog'; [1] pl.: nebulae, nebulæ, or nebulas[2][3][4][5]) is a distinct luminescent part of interstellar medium, which can consist of ionized, neutral, or molecular hydrogen and also cosmic dust. Nebulae are often star-forming regions, such as in the Pillars of Creation in the Eagle Nebula.
The Milky Way over Uluru. The Dreaming, according to Carl Strehlow, sees the Milky Way as a river connected to the dwelling of a Creator Deity. Early doubts about the precision of Spencer and Gillen's English gloss were expressed by the German Lutheran pastor and missionary Carl Strehlow in his 1908 book Die Aranda (The Arrernte).
