It Came From Outer Space
''It Came from Outer Space'' is a 1953 American science fiction horror film, the first in the 3D process from Universal-International. It was produced by William Alland and directed by Jack Arnold. The film stars Richard Carlson and Barbara Rush, and features Charles Drake, Joe Sawyer, and Russell Johnson. The script is based on Ray Bradbury's original film treatment "The Meteor" and not, as sometimes claimed, a published short story.Stafford, Jeff "Articles: 'It Came from Outer Space'." ''Turner Classic Movies''. Retrieved: January 10, 2015. ''It Came from Outer Space'' tells the story of an amateur astronomer and his fiancée who are stargazing in the desert when a large fiery object crashes to Earth. At the crash site, he discovers a round alien spaceship just before it is completely buried by a landslide. When he tells the local sheriff and newspaper editor what he saw, he is branded a crackpot. Before long, odd things begin to happen, and the disbelief turns hostile. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NGC 2419
NGC 2419 (also known as Caldwell 25) is a globular cluster in the constellation Lynx. It was discovered by William Herschel on December 31, 1788. NGC 2419 is at a distance of about 300,000 light years from the Solar System and at the same distance from the Galactic Center. NGC 2419 bears the nickname "the Intergalactic Wanderer," which was bestowed when it was erroneously thought not to be in orbit around the Milky Way. Its orbit takes it further away from the galactic center than the Magellanic Clouds, but it can (with qualifications) be considered as part of the Milky Way. At this great distance it takes three billion years to make one trip around the galaxy.Ferris, Timothy. ''Seeing in the Dark''. 2002. p. 244 The cluster is dim in comparison to more famous globular clusters such as M13. Nonetheless, NGC 2419 is a 9th magnitude object and is readily viewed, in good sky conditions, with good quality telescopes as small as 102mm (four inches) in aperture. Intrinsically it is o ...

Accretion (astrophysics)
In astrophysics, accretion is the accumulation of particles into a massive object by gravitationally attracting more matter, typically gaseous matter, in an accretion disk. Most astronomical objects, such as galaxies, stars, and planets, are formed by accretion processes. Overview The accretion model that Earth and the other terrestrial planets formed from meteoric material was proposed in 1944 by Otto Schmidt, followed by the ''protoplanet theory'' of William McCrea (1960) and finally the ''capture theory'' of Michael Woolfson. For details of Kant's position, see In 1978, Andrew Prentice resurrected the initial Laplacian ideas about planet formation and developed the ''modern Laplacian theory''. None of these models proved completely successful, and many of the proposed theories were descriptive. The 1944 accretion model by Otto Schmidt was further developed in a quantitative way in 1969 by Viktor Safronov. He calculated, in detail, the different stages of terrestrial plane ...

Fornax 4
Fornax () is a constellation in the southern celestial hemisphere, partly ringed by the celestial river Eridanus. Its name is Latin for furnace. It was named by French astronomer Nicolas Louis de Lacaille in 1756. Fornax is one of the 88 modern constellations. The three brightest stars—Alpha, Beta and Nu Fornacis—form a flattened triangle facing south. With an apparent magnitude of 3.91, Alpha Fornacis is the brightest star in Fornax. Six star systems have been found to have exoplanets. The Fornax Dwarf galaxy is a small faint satellite galaxy of the Milky Way. NGC 1316 is a relatively close radio galaxy. It is the 41st largest constellation in the night-sky, occupying an area of 398 square degrees. It is located in the first quadrant of the southern hemisphere (SQ1) and can be seen at latitudes between +50° and -90° during the month of December. History The French astronomer Nicolas Louis de Lacaille first described the constellation in French as ''le Fourneau Chy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Palomar 14
Palomar 14 is a globular cluster located in the constellation Hercules. It is a member of the Palomar Globular Clusters group. Palomar 14 was discovered in 1958 by Sidney van den Bergh and Halton Arp during inspection of the photographic plates from the Palomar Sky Survey. This is a round, diffuse cluster located in the outer halo of the Milky Way galaxy. It is about 3–4 billion years younger than a typical galactic cluster. The metallicity of the cluster is e/H= −1.50, indicating a lower abundance of elements with mass greater that helium compared to the Sun. The combined mass of the main sequence stars in the cluster is , and the combined mass of observed stars within the half-light radius is . (This is the inner radius of the cluster that emits half the total luminosity.) These mass estimates provide lower bounds for determining the total mass of the cluster. The median radial velocity of stars within the cluster is . Because of the cluster's location on the o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palomar 12
Palomar 12 is a globular cluster in the constellation Capricornus, and is a member of the Palomar Globular Clusters group. First discovered on the National Geographic Society – Palomar Observatory Sky Survey plates by Robert George Harrington and Fritz Zwicky, it was initially catalogued as a globular cluster; however, Zwicky came to believe it was actually a nearby dwarf galaxy in the Local Group. It is a relatively young cluster, being about 30% younger than most of the globular clusters in the Milky Way. It is metal-rich with a metallicity of . It has an average luminosity distribution of . Based on proper motion studies, this cluster was first suspected in 2000 to have been captured from the Sagittarius Dwarf Elliptical Galaxy (''SagDEG'') about 1.7 Ga ago. It is now generally believed to have originated in that galaxy and is associated with the Sagittarius Stream. It is estimated to be 6.5 Gyr old. See also *Messier 54 References External links Si ...

Palomar 4
Palomar 4 is a globular cluster of the Milky Way galaxy belonging to the Palomar Globular Clusters group. It was discovered in 1949 by Edwin Hubble and again in 1955 by A. G. Wilson. Based on measurements of the stars from the Gaia spacecraft, it is at least from the Sun. This star cluster is further away than the SagDEG satellite galaxy. Initially it was thought to be a dwarf galaxy A dwarf galaxy is a small galaxy composed of about 1000 up to several billion stars, as compared to the Milky Way's 200–400 billion stars. The Large Magellanic Cloud, which closely orbits the Milky Way and contains over 30 billion stars, is so ..., and it was given the name Ursa Major Dwarf.
