What are the 4 types of galaxies?
In 1936, Hubble debuted a way to classify galaxies, grouping them into four main types: spiral galaxies, lenticular galaxies, elliptical galaxies, and irregular galaxies.
More than two-thirds of all observed galaxies are spiral galaxies..
Is there anything bigger than the universe?
Cosmos At Least 250x Bigger Than Visible Universe, Say Cosmologists. The universe is much bigger than it looks, according to a study of the latest observations. When we look out into the Universe, the stuff we can see must be close enough for light to have reached us since the Universe began.
What is the youngest galaxy?
Dubbed Abell2744_Y1, the galaxy is so far away that it takes about 13 billion years for light from the galaxy to reach our neighborhood. That means it appears as it was just 650 million years after the Big Bang, scientists say. The universe is estimated to be about 13.8 billion years old.
What’s bigger than a galaxy but smaller than a universe?
The Milky Way is big, but some galaxies, like our Andromeda Galaxy neighbor, are much larger. The universe is all of the galaxies – billions of them! … Our Sun is one star among the billions in the Milky Way Galaxy. Our Milky Way Galaxy is one among the billions of galaxies in our Universe.
What is the oldest thing in the universe?
With a redshift of z = 8.2, at the time of observation, the burst was the most distant known object of any kind with a spectroscopic redshift. GRB 090423 was also the oldest known object in the Universe, apart from the methuselah star. As the light from the burst took approximately 13 billion years to reach Earth.
What is a cluster of galaxies called?
A galaxy group or group of galaxies (GrG) is an aggregation of galaxies comprising about 50 or fewer gravitationally bound members, each at least as luminous as the Milky Way (about 1010 times the luminosity of the Sun); collections of galaxies larger than groups that are first-order clustering are called galaxy …
What galaxy do we live in?
the Milky WayWe live in one of the arms of a large spiral galaxy called the Milky Way. The Sun and its planets (including Earth) lie in this quiet part of the galaxy, about half way out from the centre.
What is bigger than a galaxy?
Superclusters form massive structures of galaxies, called “filaments”, “supercluster complexes”, “walls” or “sheets”, that may span between several hundred million light-years to 10 billion light-years, covering more than 5% of the observable universe. These are the largest structures known to date.
What is the smallest thing in the universe?
Though once thought to be fundamental particles on their own, in 1968 physicists found that protons and neutrons are actually made of quarks, which are indivisible. A proton contains two “up” quarks and one “down” quark. A neutron contains two down quarks and one up.
What’s the biggest thing in the universe?

It also contains the Milky Way Galaxy, which contains Solar System where the Earth orbits the Sun. Reported for reference44 more rows
How many Earths are there in space?
NASA estimates 1 billion ‘Earths’ in our galaxy alone. There are a billion Earths in this galaxy, roughly speaking.
Which is larger cluster or galaxy?
It turns out the total mass deduced from this measurement is approximately six times larger than the mass of the galaxies or the hot gas. … In a typical cluster perhaps only 5% of the total mass is in the form of galaxies, maybe 10% in the form of hot X-ray emitting gas and the remainder is dark matter.
What is the oldest type of galaxy?
Curious enough, the smallest galaxies are also the elliptical types. The oldest and farthest galaxy ever discovered is an irregular type of galaxy called GN-z11. It is 32 billion light-years / 9.8 billion parsecs away from us. It is estimated that the galaxy formed just around 400 million years after the Big Bang.
What is the most dangerous thing in the universe?
neutron stars are the densest things that are not black holes in there cause we might find the most dangerous substance in existence strange. matter a bizarre. thing so extreme that it bends the rules of the universe. and could infect and destroy everything it comes into contact with.
