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 radius (R ☉) Method [a] Notes Orbit of Saturn: 2,047 – 2,049.9 [8] [b] Reported for reference: Theoretical limit of star size (Milky Way) ≳1,700 [9] L/T eff: Estimated by measuring the fraction of red supergiants at higher luminosities in a large sample of supernova ...
The nature of the Milky Way's bar, which extends across the Galactic Center, is also actively debated, with estimates for its half-length and orientation spanning between 1–5 kpc (short or a long bar) and 10–50°. [23] [25] [27] Certain authors advocate that the Milky Way features two distinct bars, one nestled within the other. [28]
The Milky Way started out small and grew in size as it merged with other galaxies, gaining stars as well as hydrogen to form more stars. Each galaxy has hydrogen gas that aids in the birth of stars.
The Sagittarius Stream is a stream of stars in polar orbit around the Milky Way leeched from the Sagittarius Dwarf. The Virgo Stellar Stream is a stream of stars that is believed to have once been an orbiting dwarf galaxy that has been completely distended by the Milky Way's gravity.
NASA’s James Webb Space Telescope imaged sections of the outskirts of the Milky Way galaxy, a region called the Extreme Outer Galaxy. As shown here, the telescope observed newly formed stars and ...
Distances of the nearest stars from 20,000 years ago until 80,000 years in the future Visualisation of the orbit of the Sun (yellow dot and white curve) around the Galactic Centre (GC) in the last galactic year. The red dots correspond to the positions of the stars studied by the European Southern Observatory in a monitoring programme. [71]
The supermassive black hole at the center of our Milky Way galaxy is associated with wanton destruction, but a recent discovery throws that assumption into question. A team of international ...
