Enrico Fermi (1901–1954) The Fermi paradox is a conflict between the argument that scale and probability seem to favor intelligent life being common in the universe, and the total lack of evidence of intelligent life having ever arisen anywhere other than on Earth. The first aspect of the Fermi paradox is a function of the scale or the large ...
Star Frontiers is a space opera role-playing game that is set near the center of a spiral galaxy (the setting does not specify whether the galaxy is our own Milky Way ). A previously undiscovered quirk of the laws of physics allows starships to jump to "The Void", a hyperspatial realm that greatly shortens the travel times between inhabited ...
List of stellar streams. This is a list of stellar streams. A stellar stream is an association of stars orbiting a galaxy. It was once a globular cluster or dwarf galaxy that has now been torn apart and stretched out along its orbit by tidal forces. [1] An exception in the list about Milky Way streams given below is the Magellanic Stream ...
For a four-day coverage plan on a 20-year-old car, it was about $50. This worked out to a manageable $12.50 per day, but it’s important to note that actual rates will vary based on the details ...
Construction of the pipeline commenced in August 1942 and terminated on March 2, 1944. By the end of the war, over 350 million barrels (56,000,000 m 3) of crude flowed from East Texas to the northeast states through the Big Inch. [12] [10] : 266–271. In the middle of the 20th century, the East Texas Oil Field was the center of a slant-hole ...
This gave an isophotal diameter for the Milky Way at 26.8 ± 1.1 kiloparsecs (87,400 ± 3,600 light-years), by assuming that the galactic disc is well represented by an exponential disc and adopting a central surface brightness of the galaxy (μ 0) of 22.1 ± 0.3 B-mag/arcsec −2 and a disk scale length (h) of 5.0 ± 0.5 kpc (16,300 ± 1,600 ly).
Sagittarius A*, abbreviated Sgr A* ( / ˈsædʒ ˈeɪ stɑːr / SADGE-AY-star [3] ), is the supermassive black hole [4] [5] [6] at the Galactic Center of the Milky Way. Viewed from Earth, it is located near the border of the constellations Sagittarius and Scorpius, about 5.6° south of the ecliptic, [7] visually close to the Butterfly Cluster ...
