How many galaxies are there?Bruce FitzGerald
Webb's powerful mirrors will allow scientists to look at galaxy formation — including the role of dark matter — up close. While this investigation doesn't directly answer how many galaxies there are in the universe, it does help scientists better understand the processes behind the galaxies we...

Current estimates suggest there may be as many as two trillion—that's trillion with a T—galaxies in the observable universe. More From Popular Mechanics Each galaxy has its own unique set of features and characteristics. Over the course of millions of years, they form gases, dust, stars...
There are many types of galaxies spanning all sorts of shapes and sizes. We know that they're very old and formed early in the evolution of the universe. Yet how they formed and evolved into their various shapes remains a mystery. When astronomers look into the deepest reaches of the unive...
How many galaxies are there? How many black holes are there in the universe? What is the biggest thing in the universe? Missions such as theGaia mission, a European Space Agency space probe that launched in 2013, may provide further answers. Gaia aims to precisely map about 1 billion stars...
How many galaxies are there in the universe 2021? To do that, they take very detailed pictures of small parts of the sky and count all the galaxies they see in those pictures. That number is then multiplied by the number of pictures needed to photograph the whole sky. The answer: There...
If you’ve ever asked questions like: How old are the stars? When did the universe begin? How many galaxies are there? Do aliens exist? Or why do planets have rings? then consider pursuing a career as an astronomer. Maybe your next discovery will change the world....
Do you know how many stars there are in the universe? The answer is MANY! Our sun is one of about 100 billion stars in our galaxy, the Milky Way. But the Milky Way is just one of billions of galaxies that we know about! Some other scientists say there are 2,000,000,000,000,000...
A Scientists have many theories about how new planets are born. But they have never seen one actually take shape until now. Astronomers using the European Southern Observatory's Very Large Telescope believe they have spotted a baby planet forming in deep space. “If we are correct, this is ...
