How many galaxies are in Abell 2744?
The immense gravity in Abell 2744 acts as a gravitational lens to warp space and brighten and magnify images of nearly 3,000 distant background galaxies.
How far away is Abell 2744?
approximately 4 billion light years
Abell 2744, nicknamed Pandora’s Cluster, is a giant galaxy cluster resulting from the simultaneous pile-up of at least four separate, smaller galaxy clusters that took place over a span of 350 million years, and is located approximately 4 billion light years from Earth.
How old is Abell 2744?
3.5 billion years ago
It shows some of the faintest and youngest galaxies ever detected in space. Abell 2744, located in the constellation Sculptor, appears in the foreground of this image. It contains several hundred galaxies as they looked 3.5 billion years ago.

How we know that dark matter exists from observing the bullet cluster?
Though dark matter has not been detected with telescopes, we know it exists because of its effect on objects we do see—objects that emit or reflect light. When space is warped by dark matter’s gravity, the light of distant galaxies appears distorted.
How far away is the Bullet Cluster?
3.721 billion light yearsBullet Cluster / Distance to Earth
The “Bullet Cluster” is an extremely important object for astrophysical research including studies of dark matter. This cluster was formed after the violent collision of two large clusters of galaxies moving at great speeds. The Bullet Cluster is located about 3.8 billion light years from Earth.
Does dark matter have gravity?
The even distribution means that dark energy does not have any local gravitational effects, but rather a global effect on the universe as a whole. This leads to a repulsive force, which tends to accelerate the expansion of the universe.
How many galaxies are in the Bullet Cluster?

Where is the Bullet Cluster located?
The “Bullet Cluster” is an extremely important object for astrophysical research including studies of dark matter. This cluster was formed after the violent collision of two large clusters of galaxies moving at great speeds. The Bullet Cluster is located about 3.8 billion light years from Earth.
What galaxy is 500 million light years away?
the Cartwheel galaxy
Scientists have spotted an astonishing event happening in the Cartwheel galaxy, 500 million light-years away from Earth. The galaxy lies in the constellation Sculptor and was once a normal spiral galaxy, but a collision with a smaller companion star system gave it its signature appearance.
Where is the hot gas in the Bullet Cluster?
The bullet-shaped clump on the right is the hot gas from one cluster, which passed through the hot gas from the other larger cluster during the collision.
What happens after death human?
After death, the human body undergoes a series of biological changes, collectively referred to as decomposition. These changes stem from two key factors: the cessation of biological functions within the body. the spread and activity of bacteria after death.
What’s the farthest thing from Earth?
The most distant object ever seen from Earth may have just been discovered. HD1 is an object estimated to lie around 13.3 billion light years away from our planet, placing it in an era when many chemical elements were yet to form.
How far is farthest star?
28 billion light-years away
The research team that detected this star named it Earendel, which is old English for morning star. Earendel is extremely far away from earth – 28 billion light-years away, to be exact.
