The Milky Way Galaxy is our home galaxy in the universe. It is a fairly typical barred spiral with four major arms in its disk, at least one spur, and a newly discovered outer arm. The galactic centre, which is located about 26,000 light-years from Earth, contains at least one superma...
Milky Way Galaxy (sometimes simply called the Galaxy), large spiral system of about several hundred billion stars, one of which is the Sun. It takes its name from the Milky Way, the irregular luminous band of stars and gas clouds that stretches across th
If you had to give your celestial "address" to someone on another planet in a galaxy far, far away, it would read something like, "561 Lilac Crest Lane, Coopersville, Washington 99362, United States, Planet Earth, third planet from the sun, Orion Arm, Milky Way galaxy." As a galactic ...
Lying at the very heart of the Milky Way is asupermassive black holecalled Sagittarius A*. About 4 million times the mass of the sun, this beast consumes anything that strays too close, gorging on an ample supply of stellar material enabling it to grow into a giant. In 2022, weimaged t...
The Milky Way Galaxy is an immense and very interesting place. Not only does it measure some 120,000–180,000 light-years in diameter, it is home to planet Earth, the birthplace of humanity. Our Solar System resides roughly 27,000 light-years away from the Galactic Center, on the inner...
in the Milky Way is thinner than in our solar system, but the galaxy’s gravity keeps most gas and dust nearby, at about 10,000 atoms per cubic meter on average. The matter in the space between galaxies has the lowest density in the universe, at 1 atom per cubic meter on average.[...
Galaxy Classification Astronomers sort galaxies into three main types by their shapes:spirals,ellipticals, andirregulars, and further divide them into subtypes based on their particular characteristics. Facts about Galaxies Find out more about one of the galaxies by selecting it below....
The Andromeda galaxy is the most distant object in the sky that you can see with your unaided eye. It's also on a collision course with our Milky Way.
Milky way galaxy black hole:The first image of a massive black hole at the centre of our milky way galaxy is out. The world on May 12, 2022, got to see the first wild but fuzzy image of the supermassive black hole. According to the astronomers, nearly al...
On a related note, astronomers are still unsure exactly how much our galaxy weighs, with estimates ranging from 700 billion to 2 trillion times the mass of our sun. Getting a better grasp is no easy task. Most of the Milky Way's mass — perhaps 85 percent — is in the form of dark...
