Is Canis Major a galaxy?
A small, irregular galaxy with a mass of about a billion solar masses, the Canis Major dwarf galaxy is one of our closest neighbours, lying approximately 25,000 light years from the Sun and 42,000 light years from the centre of the Milky Way.
Is the Milky Way in the Virgo Supercluster?
The Virgo Supercluster (Virgo SC) or the Local Supercluster (LSC or LS) is a mass concentration of galaxies containing the Virgo Cluster and Local Group, which in turn contains the Milky Way and Andromeda galaxies.
How old are spiral galaxies?
Astronomers have discovered the universe’s most ancient spiral galaxy yet, a cosmic structure that dates back roughly 10.7 billion years, a new study reveals.
What does Maffei mean?
noun. Astronomy. Either of two galaxies (“Maffei 1” and “Maffei 2”) near the galactic equator which are visible only in red and infrared light owing to the heavy extinction of shorter-wavelength light by interstellar dust.
How old is Canis Major?
around 2.2 billion years old
Around 15 light-years in diameter, it is located 3700 light-years away from Earth, and has been dated to around 2.2 billion years old. NGC 2362 is a small, compact open cluster, 5200 light-years from Earth. It contains about 60 stars, of which Tau Canis Majoris is the brightest member.
How big are black holes?
These types of black holes are only a few miles across. Black holes have also been discovered in the centers of some galaxies. These black holes are very large and contain the same amount of material as 100 million or more suns. These types of black holes are several million miles across.
How far away is Maffei 1 from the Sun?
Distance. Maffei 1 moves away from the Sun at the speed of about 66 km/s. Its velocity relative to the Local Group’s center of mass is, however, 297 km/s away. That means that Maffei 1 participates in the general expansion of the Universe.
What is the difference between Maffei 1 and Maffei 2?
Maffei 1 is a large elliptical galaxy. At about 9,800,000 light-years’ distance, it is part of the nearest group of galaxies to the Local Group. This group is called the Maffei 1 Group, or the IC 342 Group, after the large spiral galaxy IC 342. Maffei 2 has a spiral structure and is at the same distance as Maffei 1.
Where is Maffei 1 in the Milky Way?
Lying near the border between the constellations Perseus and Cassiopeia, they are close to the plane of the Milky Way, where obscuring dust clouds in interstellar space prevent nearly all visible light emitted by external galaxies from reaching Earth. Maffei 1 is a large elliptical galaxy.
Is Maffei 1 in the expansion of the universe?
Maffei 1 moves away from the Sun at the speed of about 66 km/s. Its velocity relative to the Local Group’s center of mass is, however, 297 km/s away. That means that Maffei 1 participates in the general expansion of the Universe.
