How old is our galaxy?
13.51 billion yearsMilky Way/Age.
Is Earth the only planet with life?
Earth is the only planet in the universe known to possess life. The planet boasts several million species of life, living in habitats ranging from the bottom of the deepest ocean to a few miles into the atmosphere. And scientists think far more species remain to be discovered.
Where is Earth in the galaxy?
Orion ArmWe live in a seemingly nondescript neighborhood in the Milky Way galaxy, in a small spiral arm called the Orion Arm.
What is the biggest galaxy in the universe?
IC 1101The biggest known galaxy is IC 1101, which is 50 times the Milky Way’s size and about 2,000 times more massive. It is about 5.5 million light-years across. Nebulas, or vast clouds of gas, also have impressively large sizes.
Which universe do we live in?
Our home galaxy, the Milky Way, contains at least 100 billion stars, and the observable universe contains at least 100 billion galaxies. If galaxies were all the same size, that would give us 10 thousand billion billion (or 10 sextillion) stars in the observable universe.
Do we live in a galaxy or universe?
A galaxy is a huge collection of gas, dust, and billions of stars and their solar systems, all held together by gravity. We live on a planet called Earth that is part of our solar system. But where is our solar system? It’s a small part of the Milky Way Galaxy.
Can humans live Uranus?
As an ice giant, Uranus doesn’t have a true surface. The planet is mostly swirling fluids. While a spacecraft would have nowhere to land on Uranus, it wouldn’t be able to fly through its atmosphere unscathed either. The extreme pressures and temperatures would destroy a metal spacecraft.
Who created God?
Defenders of religion have countered that the question is improper: We ask, “If all things have a creator, then who created God?” Actually, only created things have a creator, so it’s improper to lump God with his creation. God has revealed himself to us in the Bible as having always existed.
What are the 4 types of galaxy?
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.
Can we go to another galaxy?
According to our current understanding of physics, an object within space-time cannot exceed the speed of light, which means an attempt to travel to any other galaxy would be a journey of millions of earth years via conventional flight.
Who is the creator of universe?
GodMany religious persons, including many scientists, hold that God created the universe and the various processes driving physical and biological evolution and that these processes then resulted in the creation of galaxies, our solar system, and life on Earth.
Do we live in the solar system?
Our solar system is the only place we know of that harbors life, but the farther we explore the more we find potential for life in other places.
What shape is an irregular galaxy?
An irregular galaxy is a galaxy that does not have a distinct regular shape, unlike a spiral or an elliptical galaxy. Irregular galaxies do not fall into any of the regular classes of the Hubble sequence, and they are often chaotic in appearance, with neither a nuclear bulge nor any trace of spiral arm structure.
What does Earth look like from space right now?
From space, Earth looks like a blue marble with white swirls. Some parts are brown, yellow, green and white. The blue part is water.
How old is our world?
4.543 billion yearsEarth/Age
What does our universe look like?
Nearby, the stars and galaxies we see look very much like our own. … In our own backyard, the Universe is full of stars. But go more than about 100,000 light years away, and you’ve left the Milky Way behind. Beyond that, there’s a sea of galaxies: perhaps two trillion in total contained in our observable Universe.
What type of galaxy do we live in?
Milky Way GalaxyThey come in a variety of shapes and sizes. The Milky Way is a large barred spiral galaxy. All the stars we see in the night sky are in our own Milky Way Galaxy. Our galaxy is called the Milky Way because it appears as a milky band of light in the sky when you see it in a really dark area.
How do you identify a galaxy?
Astronomer Edwin Hubble devised a method for identifying kinds of galaxies. Astronomer Edwin Hubble, after whom the space telescope is named, classified galaxies according to shape. The Hubble scale chart takes a wishbone, or tuning fork shape. Armless, elliptical galaxies are on the left.
