What type of galaxy is NGC 4622?
NGC 4622 is a rare example of a spiral galaxy with arms pointing in opposite directions. What caused this galaxy to behave differently from most galaxies? Astronomers suspect that NGC 4622 interacted with another galaxy. Its two outer arms are lopsided, meaning that something disturbed it.
Who discovered NGC 4622?
On May 25 2001, an image taken by the Hubble Space Telescope captured a supernova in NGC 4622. It was discovered by R. Buta and GG Byrd of the University of Alabama as well as T. Freeman of Bevill State Community College.
When was the backwards galaxy discovered?
It was taken in May 2001 by Hubble’s Wide Field and Planetary Camera 2, designed and built by NASA’s Jet Propulsion Laboratory, Pasadena, Calif.
How big is the backwards galaxy?
1.7′ x 1.6′
Backward Galaxy – unbarred spiral galaxy Backward Galaxy , is a unbarred spiral located in the constellation Centaurus . Backward Galaxy is magnitude 12.6*, is 200 million light-years away, and is 1.7′ x 1.6′ in size.
What kind of galaxy is NGC 1365?
NGC 1365 is an enormous, visually-stunning spiral galaxy located in the Fornax Cluster. At 20,000 lightyears across (twice the length of the Milky Way), it’s one of the largest galaxies currently known to astronomers.
What does M83 look like?
M83 is a barred spiral galaxy, likely similar in structure to our own Milky Way. Knots of red hydrogen-alpha light mark star-forming regions in this visible-light view. M83 is often cited as a close match to how our own Milky Way might appear from afar — though it’s only half as big, about 40,000 light-years across.
Which way do spiral galaxies rotate?
About half of all spiral galaxies appear to be rotating clockwise and the other half counterclockwise. The direction a galaxy rotates depends on your perspective. As an analogy, consider a spinning bicycle wheel. When you look at a spinning wheel from one side, it looks like it’s spinning clockwise.
What is the oldest thing in the galaxy?
The oldest known galaxy in existence remains GN-z11, which formed around 400 million years after the Big Bang, as previously reported by Live Science’s sister site Space.com.
How many stars are in a spiral galaxy?
Estimate of stars varies from 200 billion to 400 billion. Milky way is a barred spiral.
Where is the spiral galaxy NGC 4622 located?
The spiral galaxy, NGC 4622 (also called backward galaxy), lies approx. 111 million light years away from Earth in the constellation Centaurus.
Is the Galaxy 4622 part of the Centaurus Cluster?
The type of supernova was not determined. According to AM Garcia, NGC 4622 is a member of the NGC 4709 group which consists of at least 42 galaxies including NGC 4616, NGC 4622B (also called PGC 42852 ), NGC 4679 and NGC 4709. The NGC 4709 group is part of the Centaurus Cluster.
Why was the discovery of NGC 4622 met with skepticism?
These results were met with skepticism in part because they contradicted conventional wisdom with one quote being “so you’re the backward astronomers who found the backward galaxy.” The fact that a pair of arms could lead was not easy to accept.
When did the Hubble Space Telescope capture NGC 4622?
On May 25 2001, an image taken by the Hubble Space Telescope captured a supernova in NGC 4622. It was discovered by R. Buta and GG Byrd of the University of Alabama as well as T. Freeman of Bevill State Community College. The type of supernova was not determined.
