Immediately after the Big Bang, which occurred around 13.8 billion years ago, the universe was dominated by unimaginably high ...

Image: This computer-simulated image shows the formation of two high density regions (yellow) in the early universe, approximately 200 million years after the Big Bang.

Everything that we can see and detect — the stars and galaxies — only makes up a puny 5% of the universe, whereas dark matter comprises 25%.

The shapes of clouds and, ultimately, star formation are influenced by how gas flows within them. Going forward, my colleagues and I are incorporating colors into our 3-D prints to explore the ...

The universe's mass was calculated to be equivalent to around 2 trillion trillion (2 followed by 36 zeroes) suns, or 1,900 "zetta-suns" (a "zetta" refers to a hypothetical star so huge it has a ...

“An entire population [of water-rich stars and planets] in the early universe might create this hazy water … emission background,” Whalen says.

"We're finding star formation in the early universe is much more complicated than we thought," added Rieke. These results are being reported at the 242 nd meeting of the American Astronomical ...

Second, it was a lot darker because stars and galaxies had not yet formed. Back then, the universe was composed of dark matter (whatever is it) and neutral hydrogen and helium.

Previous models of star formation provided widely varying predictions, creating uncertainty about the universe’s early development. Radio Signals Offer New Insights ...

Compared with other observed galaxies in the early universe, A1689-zD1 doesn’t make a lot of stars — only about 30 suns each year — meaning the galaxy isn’t very bright to our telescopes.

The outer arm of the spiral in this huge, oddly shaped stellar nursery — called NGC 346 — may be feeding star formation in a river-like motion of gas and stars.
