HD 140283 (also known as the Methuselah star) is a metal-poor subgiant star about 200 light years away from the Earth in the constellation Libra, near the boundary with Ophiuchus in the Milky Way Galaxy. Its apparent magnitude is 7.205, so it can be seen with binoculars. It is one of the oldest stars known.
OGLE-2005-BLG-390Lb (known sometimes as Hoth by NASA [1]) is a super-Earth ice exoplanet orbiting OGLE-2005-BLG-390L, a star 21,500 ± 3,300 light-years (6,600 ± 1,000 parsecs) from Earth near the center of the Milky Way, making it one of the most distant planets known.
The discovery of the star in the Milky Way Galaxy suggests that the galaxy may be at least 3 billion years older than previously thought. [265] [266] [267] Several individual stars have been found in the Milky Way's halo with measured ages very close to the 13.80-billion-year age of the Universe.
The find, announced Wednesday, can help explain how solar systems across the Milky Way galaxy came to be. A six-planet solar system in perfect synchrony has been found in the Milky Way Skip to ...
Kapteyn's Star is distinctive in a number of regards: it has a high radial velocity, [13] orbits the Milky Way retrograde, [16] and is the nearest-known halo star to the Sun. [18] It is a member of a moving group of stars that share a common trajectory through space, named the Kapteyn moving group. [19]
Both were once considered to be part of the Local Group, [6] but are now known to be among the dozen bright spiral galaxies near the Milky Way but beyond the confines of the Local Group. [7] NGC 6946 lies within the Virgo Supercluster. [8] The galaxy was discovered by William Herschel on 9 September 1798.
They were both discovered by Albert Marth on Mar 3, 1864. [4] To some astronomers, the galaxy looks like a penguin or a porpoise. [5] NGC 2936, NGC 2937, and PGC 1237172 are included in the Atlas of Peculiar Galaxies as Arp 142 in the category "Galaxy triplet". On 20 June 2013, the Hubble Space Telescope examined and photographed NGC 2936. [5]
ULAS J0015+01 is the designation given to a star discovered on July 10, 2014 as the farthest star in bound of the gravitational attraction of the Milky Way galaxy. It is estimated to lie at 900,000 light-years from the Earth, beyond the reaches of the Magellanic Clouds. [1] Another star, ULAS J0744+25, was a bit closer. [2]
