Are there 2 trillion galaxies?
Are there 2 trillion galaxies?
“A detailed theoretical simulation predicted far more faint, small galaxies than we’ve seen, upping the expected total to closer to 2 trillion. But recent observational evidence shows that even that estimate is far too low. Instead, there are between 6 and 20 trillion galaxies out there.”
How many stars are in each galaxy?
“Using the Milky Way as our model, we can multiply the number of stars in a typical galaxy (100 billion) by the number of galaxies in the universe (2 trillion).”
Are there more stars than grains of sand?
“The numbers pretty much matched. There are about the same number of stars in the observable universe as there are sand grains in all of Earth’s beaches.”
Are there infinite stars?
“Answer A : No, the number of stars cannot be infinite. This number may be very big, but it has a definite value. The same goes for stars.”
What is the deadliest galaxy?
“The Triangulum Galaxy is a spiral galaxy 2.73 million light-years (ly) from Earth in the constellation Triangulum. It is catalogued as Messier 33 or NGC (New General Catalogue) 598….”
“
| Triangulum Galaxy | |

| Galactocentric velocity | -44 ± 6 km/s |
| Distance (comoving) | 970 kpc (3.2 Mly) |
| Apparent magnitude (V) | 5.72 |

Can we go beyond galaxy?
“The technology required to travel between galaxies is far beyond humanity’s present capabilities, and currently only the subject of speculation, hypothesis, and science fiction. However, theoretically speaking, there is nothing to conclusively indicate that intergalactic travel is impossible.”
What is the closest star to Earth?
“Distance Information Proxima Centauri, the closest star to our own, is still 40,208,000,000,000 km away.”
How many universes are there?
“In a new study, Stanford physicists Andrei Linde and Vitaly Vanchurin have calculated the number of all possible universes, coming up with an answer of 10^10^16.”
How many universes are in space?
“While estimates among different experts vary, an acceptable range is between 100 billion and 200 billion galaxies, said Mario Livio, an astrophysicist at the Space Telescope Science Institute in Baltimore, Maryland.”
What is the beyond the universe?
“The trite answer is that both space and time were created at the big bang about 14 billion years ago, so there is nothing beyond the universe. However, much of the universe exists beyond the observable universe, which is maybe about 90 billion light years across.”
Is space infinite?
“There’s a limit to how much of the universe we can see. The observable universe is finite in that it hasn’t existed forever. It extends 46 billion light years in every direction from us. (While our universe is 13.8 billion years old, the observable universe reaches further since the universe is expanding).”
How many galaxies are there?
“The Hubble Deep Field, an extremely long exposure of a relatively empty part of the sky, provided evidence that there are about 125 billion (1.25×1011) galaxies in the observable universe.”
Can human Go to star?
“The nearest star is 25,300,000,000,000 miles (about 39,900,000,000,000 kilometers) away. It would take the fastest rockets that we have thousands of years to reach it. It is always possible that sometime in the future people may find a way to travel to the stars, but right now we just do not have the technology.”
Can human make a star?
“There is no way to “ignite” a gas giant: even if you could temporarily start fusion in it’s core, any artificially-generated reaction like this would be self-limiting: the energy it creates causes the proto-star to expand a little bit, and then nothing else happens.”
Can human touch stars?
“No. While none exist to date it would be possible for a dead star to have cooled to a safe temperature. However, such objects are inherently supported by degeneracy pressure–they’re very dense.”
Who saw the galaxy first?
“964 — Abd al-Rahman al-Sufi (Azophi), a Persian astronomer, makes the first recorded observations of the Andromeda Galaxy and the Large Magellanic Cloud in his Book of Fixed Stars, and which are the first galaxies other than the Milky Way to be observed from Earth.”
What is the prettiest galaxy?
“NGC 2336 is the quintessential galaxy — big, beautiful, and blue — and it is captured here by the NASA/ESA Hubble Space Telescope.”
What is the biggest universe?
“The biggest single entity that scientists have identified in the universe is a supercluster of galaxies called the Hercules-Corona Borealis Great Wall. It’s so wide that light takes about 10 billion years to move across the entire structure.”
Are there 200 billion galaxies?
“All in all, Hubble reveals an estimated 100 billion galaxies in the universe or so, but this number is likely to increase to about 200 billion as telescope technology in space improves, Livio told Space.com.”
How many possible galaxies are there?
“If we made the most straightforward estimate using today’s best technology, we’d state there are 170 billion galaxies in our Universe. But we know more than that, and our modern estimate is even grander: two trillion galaxies.”
Why can’t we see a 15 billion year old galaxy?
“Answer and Explanation: Because the universe is estimated to be less than 14 billion years old, conventional wisdom would indicate that we can’t see a galaxy 15 billion light-years away because, if anything exists 15 billion light-years away at all, its light hasn’t had enough time to reach us.”
Are there 200 billion stars in our galaxy?
“Using the Milky Way as our model, we can multiply the number of stars in a typical galaxy (100 billion) by the number of galaxies in the universe (2 trillion). The answer is an absolutely astounding number. There are approximately 200 billion trillion stars in the universe.”
