The Milky Way [c] is the galaxy that includes the Solar System, with the name describing the galaxy's appearance from Earth: a hazy band of light seen in the night sky formed from stars that cannot be individually distinguished by the naked eye.
List of the largest known stars in the Milky Way Star name Solar radii (Sun = 1) Method Notes Orbit of Saturn: 2,047 – 2,049.9: Reported for reference: WOH G64 (For comparison) 1,540 ± 77: L/T eff: Located in the Large Magellanic Cloud. Possibly the largest known star. Theoretical limit of star size (Milky Way)
Night on the Galactic Railroad (銀河鉄道の夜, Ginga Tetsudō no Yoru), sometimes translated as Milky Way Railroad, Night Train to the Stars or Fantasy Railroad in the Stars, is a classic Japanese fantasy novel by Kenji Miyazawa written around 1927.
The Laniakea Supercluster (/ ˌ l ɑː n i. ə ˈ k eɪ. ə /; Hawaiian for "open skies" or "immense heaven") is the galaxy supercluster that is home to the Milky Way and approximately 100,000 other nearby galaxies.
A NASA conception of the collision using computer-generated imagery. The Andromeda–Milky Way collision is a galactic collision predicted to occur in about 4.5 billion years between the two largest galaxies in the Local Group —the Milky Way (which contains the Solar System and Earth) and the Andromeda Galaxy.
A tour of the Milky Way; a look at the massive black hole with the mass of thousands of suns, that lies at its center; how the death of old stars provide the material to create new ones; and how stars from the galactic center are being catapulted beyond the outer arms at unimaginable speeds.
Based on mass and increasingly precise radius limits, astronomers have concluded that Sagittarius A* must be the central supermassive black hole of the Milky Way galaxy. The current value of its mass is 4.297 ± 0.012 million solar masses .
Supercluster. A map of the superclusters and voids nearest to Earth. A supercluster is a large group of smaller galaxy clusters or galaxy groups; [1] they are among the largest known structures in the universe. The Milky Way is part of the Local Group galaxy group (which contains more than 54 galaxies), which in turn is part of the Virgo ...
For example, the Milky Way galaxy has a supermassive black hole at its center, corresponding to the radio source Sagittarius A*. Accretion of interstellar gas onto supermassive black holes is the process responsible for powering active galactic nuclei (AGNs) and quasars.
A Super-Earth is a type of exoplanet with a mass higher than Earth 's, but substantially below those of the Solar System's ice giants, Uranus and Neptune, which are 14.5 and 17 times Earth's, respectively. [1] The term "super-Earth" refers only to the mass of the planet, and so does not imply anything about the surface conditions or habitability.
