NASA recently released images of the Andromeda galaxy, an empire of stars, that is the Milky Way galaxy's closest neighbor. This photo shows the Milky Way as seen from Black Balsam, mountain range ...
The Andromeda Galaxy is visible to the naked eye in dark skies. [21] Around the year 964 CE, the Persian astronomer Abd al-Rahman al-Sufi described the Andromeda Galaxy in his Book of Fixed Stars as a "nebulous smear" or "small cloud". [22] Star charts of that period labeled it as the Little Cloud. [23]
The Sun, the orbit of Earth, Jupiter, and Neptune, compared to four stars (Pistol Star, Rho Cassiopeiae, Betelgeuse, and VY Canis Majoris) Overview Although red supergiants are often considered the largest stars, some other star types have been found to temporarily increase significantly in radius, such as during LBV eruptions or luminous red ...
Zooming In on the Andromeda Galaxy, also known as Gigapixels of Andromeda, is a 2015 composite photograph of the Andromeda Galaxy produced by the Hubble Space Telescope. It is 1.5 billion pixels in size, and is the largest image ever taken by the telescope. [1] At the time of its release to the public, the image was one of the largest ever ...
Although stars are more common near the centers of each galaxy, the average distance between stars is still 160 billion (1.6 × 10 11) km (100 billion mi, 1075 AU). That is analogous to one ping-pong ball every 3.2 km (2 mi). Thus, it is extremely unlikely that any two stars from the merging galaxies would collide. [6]
It was listed as entry number 34 in A Catalogue of Circumpolar Stars, published posthumously in 1838 by British astronomer Stephen Groombridge. [11] Based upon parallax measurements taken by the Gaia spacecraft, the system is located about 11.6 light-years (3.6 parsecs) from the Sun. This positions the pair among the nearest stars to the Solar ...
NGC 206 is a bright star cloud in the Andromeda Galaxy, and the brightest star cloud in Andromeda when viewed from Earth.It was discovered by German-born English astronomer William Herschel in 1786 [2] and possibly even two years earlier when he observed "a streak of milky nebulosity, horizontal, or part of the 31st Nebula."
a variable star in the constellation of Andromeda. It is classified as a semiregular variable pulsating giant star, and varies from an apparent visual magnitude of 14.5 at minimum brightness to a magnitude of 9.9 at maximum brightness, with a period of approximately 238.3 days.
