How big is the universe in miles (not in light years)? The radius of the Observable universe is estimated to be about 46 billion light years, which is about [math]2.7 \times 10^{23}[/math] miles. Note that the observable universe is just the part of the universe we can see. The universe itself is much larger than that, and it's even possible that it is infinite.

How big is the universe in miles (not in light years)? However the size of observable universe is about: 46 Billion Light Years which is about... 2.70410991 × 10^23 miles (I can't even pronounce it without using mathematical terms) nor i can phantom how big that is. note: one light year is the distance a light could travel within one year.

How can it be understood that the universe is 93 billion light years across and yet only 13.8 billion years old? There is a scale factor for the universe that is a function of time, [math]a(t)[/math]. [math]\frac{a(t_{NOW})}{a(t_{CMB})}=z+1[/math]. Which means that the diameter of those bumps that would become our CMB image would be 93 billion light years/1101 which is 84.5 million light years in diameter.

How Big are Galaxies? Alongside stars, the galaxy is the most important unit of organization in the entire universe. There are an estimated 100 billion galaxies in the visible universe, each with between about ten million and a trillion stars. The average galaxy includes about 10 71 atoms, and ten times more invisible mass in the form of dark matter.

IC 1101: The Largest Galaxy In the Known Universe IC 1101 The largest galaxy Known so Far. IC 1101 is located one billion light years away in the constellation Serpens, this is the largest galaxy in the known universe. It is enormous, it has a diameter of six million light years and a mass of over 100 trillion stars, with most of that mass in the form of elusive dark matter. astronomer Mark Brodwin said.

Title of farthest known object in universe has new champ [ The Universe: Big Bang to Now in 10 Easy Steps ]. The mini galaxy is less than 600 light-years wide; for comparison, the Milky Way is 150,000 light-years across. Astronomers think MACS0647-JD may eventually combine with other small galaxies to create a larger whole.

How Big Is The Milky Way? The Milky Way is our home galaxy, the spot where the Earth resides. We are not anywhere near the center — NASA says we’re roughly 165 quadrillion miles from the galaxy’s black hole, for example — which demonstrates just how darn big the galaxy is.

Hubble Space Telescope The farthest and one of the very earliest galaxies ever seen in the universe appears as a faint red blob in this ultra-deep–field exposure taken with NASA's Hubble Space Telescope. This is the deepest infrared image taken of the universe. Based on the object's color, astronomers believe it is 13.2 billion light-years away. (Credit: NASA, ESA, G. Illingworth (University of California, Santa Cruz), R. Bouwens (University of California, Santa Cruz, and Leiden University), and the HUDF09 Team)

Largest Structure In Universe, Large Quasar Group, Challenges Cosmological Principle The quasar group appears to violate a widely accepted assumption known as the cosmological principle, which holds that the universe is essentially homogeneous when viewed at a sufficiently large scale. Calculations suggest that structures larger than about 1.2 billion light-years should not exist, researchers said.

The Farthest Visible Reaches of Space Scientists have estimated the age of the Universe to be 13.73 billion years old (with an uncertainty of about 120 million years). When we observe an object that is 13 billion light years away, we are essentially observing it as it was 13 billion years ago, when the Universe was young.

- We can observe only a portion of the entire universe. Because the universe is only about 14 billion years old, light has only had about 14 billion years to travel through it. Therefore, the most distant regions of the universe we can see are about 14 billion light-years away. This is the extent of the observable universe, but the entire universe is probably much larger. It could even extend infinitely in all directions.

Observable universe For other uses, see Universe (disambiguation). The Universe is all of time and space and its contents. It includes planets, moons, minor planets, stars, galaxies, the contents of intergalactic space, and all matter and energy. The observable universe is about 28 billion parsecs (91 billion light-years) in diameter. The size of the entire Universe is unknown, but there are many hypotheses about the composition and evolution of the Universe.

How many stars are in the universe? In the observable universe there are about 10 billion galaxies.  Assuming galaxies have an average of 100 billion stars each, the  observable universe has about 1 billion tr…illion stars (or  1,000,000,000,000,000,000,000).

Mystery of the universeâs giant Cold Spot solved: 'Supervoid' 1.8 billion light-years wide could be the biggest object ever found Mystery of the universe’s giant Cold Spot solved: 'Supervoid' 1.8 billion light-years wide could be the biggest object ever found. A giant supervoid 1.8 billion light-years across may be responsible for a mysterious ‘Cold Spot’ in the universe. The theory was proposed by astronomers seeking to understand what is causing this larger-than-expected cold area. If confirmed, the supervoid would be the largest single structure ever found by humanity.

This galaxy is the farthest into space we have ever seen That means the edge of the universe is 13.8 billion light-years away -- so far away that we've never been able to observe it. But we're getting closer. This latest breakthrough is something special: an ultra-luminous, light-blue galaxy known as EGS-zs8-1, located in the constellation of Boötes.

- There are 10^61 Planck lengths in the observable universe. So we'll split the difference and look for something 10^30 or 10^31 Planck lengths. That's about .01 to .1 millimeters. That's on the order of the width of a fog droplet to a human hair.

How Many Stars Are There in the Sky? Let's start with the galaxies. There are, astronomers estimate, around 170 billion galaxies in the observable universe, stretching out over a radius of some 45.7 billion* light-years. Those galaxies vary in terms of the number of stars they contain, Universe Today notes: Some spiral galaxies have more than a trillion stars.

How Big is the Universe? It is reported that by using the VLBA that accurate distance measurements can be made to NGC4258 (reported to be 23.5 million light years away). Coordinating these ten radio stations to work together as the worlds largest dedicated, full-time astronomical instrument is impressive.

Facts about the Size of the Space Shuttle When you consider that the Hubble Space Telescope is 43.5 feet (13.2 m) long and 14 feet (4.2 m) wide, you can see that it almost filled the payload bay, which can handle a 15 foot (4.6 m) diameter object. Some of the components brought up to the ISS left only inches to spare on either side of bay.

How Big Is the Universe? There is every reason to think that the universe extends a long way beyond the part of the universe we can see. In fact, a variety of observations suggest that our visible patch may be a small fraction—maybe an infinitely small fraction—of the whole universe.
