Do other galaxies have different elements?

Do other galaxies have different elements?

Nope. no matter where spectroscopes have been pointed, the same elements, and their compounds keep showing up. The same goes for physics too. I’ve always been fascinated with how astronomers can determine what the stars we see at night are made of.

What elements make up galaxies?

Many of those points of light are actually galaxies — collections of millions to trillions of stars. Galaxies are composed of stars, dust and dark matter, all held together by gravity. Astronomers aren’t certain exactly how galaxies formed. After the Big Bang, space was made up almost entirely of hydrogen and helium.

Can different elements exist on different planets?

You have to consider that other planets (and indeed everything in our universe) follow the same physical laws that our planet does (the laws of our universe), so all elements created after the big bang will be common all over the universe.

How come Earth can support life and other planets Cannot?

What makes the Earth habitable? It is the right distance from the Sun, it is protected from harmful solar radiation by its magnetic field, it is kept warm by an insulating atmosphere, and it has the right chemical ingredients for life, including water and carbon.

Why are galaxies important to our existence?

Galaxies are important to our existence because they are the largest and most common star formations in the universe.

Are there different galaxies?

There are four main categories of galaxies: elliptical, spiral, barred spiral, and irregular. These types of galaxies are further divided into subcategories while at the same time other types of galaxies exist based on their size and other unique features.

How are the various types of galaxies similar or different?

Explanation: Similarity:- All the galaxies in the universe contains stars, asteroids,planets, and galactic cloud.. Difference:- They differ in the shapes where some are elliptical, some are spiral and some are even irregular.

Are there elements on other planets not on Earth?

Not in the solar system, but there do exist elements that no longer exist on earth but which do exist elsewhere. For example, there is no natural technetium on earth. Or at least, not for long: it exists briefly as part of the nuclear decay process. But it has been found in Technetium stars .

Are there elements on other planets not found on Earth?

When it comes to the elements in the periodic table found throughout the Universe, it’s only the first two that originated from the Big Bang: hydrogen and helium. …
