Are we in a galaxy?

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.

Are we in a galaxy or universe?

Our Milky Way Galaxy is one among the billions of galaxies in our Universe. You are unique in the Universe! You can observe objects in our solar system and even see other galaxies at a star party near you-and rest assured that everything you are seeing is a part of the same universe as you!

Are we inside Milky Way?

Because we are inside the Milky Way, we don't get to take any pictures of it from an angle "above" the Galaxy—for example, like this beautiful picture of M31, the Andromeda Galaxy.

In which universe do we live?

As we are part of the solar system Earth pretty much follows the path of the sun as it goes through its own orbit around the galaxy. The Milky Way is a spiral galaxy type so it has arms sort of like an octopus. The Sun is located near the outward tip of the Sagittarius arm of the Milky Way.

Can life exist in other galaxies?

Generally, they conclude, life is possible only in the outer regions of large galaxies. (Our own solar system is about 27,000 light-years from the center.) Things are even bleaker in other galaxies, the researchers report. Compared with the Milky Way, most galaxies are small and low in metallicity.

You Are Here (Part 1: Space)

Why do we not know if we live in a multiverse?

This randomness isn't the result of things we don't know – it's because the Universe itself is yet to make up its mind. There's nothing in quantum mechanics explaining this transition either, leaving us to imagine what it all means.

Do we have pictures of other galaxies?

A telescope network that has spent years staring into deep space has finally delivered some of the most gloriously detailed images we've ever seen of other galaxies.

Where do we sit in the Milky Way?

We're about 26,000 light-years from the center of the galaxy, on the inner edge of the Orion-Cygnus Arm. It's sandwiched by two primary spiral arms, the Sagittarius and Perseus Arms.

How many suns are there?

How many suns are there in this universe? There are an estimated 100 billion stars in our Milky Way galaxy alone making up about 100 billion suns.

Is Earth in a galaxy?

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. A galaxy is a huge collection of gas, dust, and billions of stars and their solar systems.

Are we in or on Earth?

Before we begin, we'd like to clarify that we do not live "inside the earth." We live on the surface of the earth. Should we have to spell this out? Probably not, but better safe than sorry.

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.

Do we have 2 suns?

(We already knew the Solar System is a total weirdo. The placement of the planets appears out of whack compared to other systems, and it's missing the most common planet in the galaxy, the super-Earth.) So, if not for some cosmic event or quirk, Earth could have had two suns. But we don't.

Can planets have 2 suns?

The twin suns on Tatooine's horizon are an enduring cinematic moment, one that questions the probability of a double sunset. Can a planet really have two suns? While many things about Star Wars are purely fictional, it turns out that planets orbiting two or more stars is not one of them.

Is black hole in Milky Way?

The Milky Way's black hole is huge compared to the black holes left behind when massive stars die (opens in new tab). But astronomers think there are supermassive black holes at the center of nearly all galaxies. Compared to most of these, Sagittarius A* is meager and unremarkable.

How far away is the oldest galaxy we've ever discovered?

Up until the discovery of HD1 in 2022, GN-z11 was the oldest and most distant known galaxy yet identified in the observable universe, having a spectroscopic redshift of z = 11.09, which corresponds to a proper distance of approximately 32 billion light-years (9.8 billion parsecs).

How old is the world?

Today, we know from radiometric dating that Earth is about 4.5 billion years old. Had naturalists in the 1700s and 1800s known Earth's true age, early ideas about evolution might have been taken more seriously.

How far have humans gone space?

Farthest away

In April 1970, the crew of NASA's Apollo 13 mission swung around the far side of the moon at an altitude of 158 miles (254 km), putting them 248,655 miles (400,171 km) away from Earth. It's the farthest our species has ever been from our home planet.

Can Hubble see Pluto?

Hubble has brought Pluto from a fuzzy, distant dot of light, to a world which we can begin to map, and watch for surface changes. Hubble's view of tiny, distant Pluto is reminiscent of looking at Mars through a small telescope," said Stern.

What do galaxies really look like?

Most galaxies are flat, but there are different shapes — some are spirals, some are elliptical, and some are irregular. What does the Milky Way look like? Our Milky Way galaxy looks a little like a pinwheel.

Is time Travelling possible?

Yes, time travel is indeed a real thing. But it's not quite what you've probably seen in the movies. Under certain conditions, it is possible to experience time passing at a different rate than 1 second per second. And there are important reasons why we need to understand this real-world form of time travel.

Did Stephen Hawking believe in multiverse?

One of the topics Hawking tinkered with toward the end of his life was the multiverse theory — the idea that our universe, with its beginning in the Big Bang, is just one of an infinite number of coexisting bubble universes.

What is inside a black hole?

The singularity at the center of a black hole is the ultimate no man's land: a place where matter is compressed down to an infinitely tiny point, and all conceptions of time and space completely break down. And it doesn't really exist.

Is Earth the only planet with life?

Earth is the only planet in the universe known to possess life. The planet boasts several million described species, living in habitats ranging from the bottom of the deepest ocean to a few miles up into the atmosphere. Researchers think far more species remain that have yet to be described to science.
