A new Big Bang model does away with speculative elements, putting gravitational waves at the forefront of the creation of ...

Let me first tell you how mysterious dark energy is. Einstein added a cosmological constant to his equations to keep the ...

A galaxy in the early universe was rich with oxygen, astronomers have found. The discovery raises questions about how early life could have first appeared in the universe.

What was the universe like in the first few hundreds of millions of years after it came into existence? How did the first ...

JERUSALEM, Sept. 4 (Xinhua) -- A new study has found that most massive stars in the early universe formed as binary systems, meaning they were born in pairs, similar to the way many massive stars form ...

Using data from the James Webb Space Telescope, astronomers have discovered dormant galaxies with a wide range of masses in the first billion years after the Big Bang, moving one step closer to ...

NASA's James Webb Space Telescope spotted three galaxies forming when the universe was about only 400 million to 600 million years old.

However, further observations from the Hubble Space Telescope revealed that Pismis 24-1 is actually a triple star system. This system includes one star 66 times the mass of our Sun, alongside a ...

As the universe expanded, the clumpiness of matter seeded galaxies and stars, which in turn produced radiation -- ultraviolet and X-rays -- that heated the gas between stars.

An impossibly bright galaxy is forcing scientists to rewrite the rules of the Big Bang’s aftermath. Here’s what you’ll learn in this story: Scientists have found a remarkably small yet bright object ...

The biggest lesson from all of it is that the galaxies -- and in particular the newly star-forming galaxies -- are the components of the Universe responsible for reionization.

That's a big deal, considering that the Universe was born without carbon, nitrogen, oxygen, silicon, sulfur, iron, or practically any of the elements we find in stars and galaxies today.
