It's going to take more than early dark energy to resolve the Hubble tension

Our best understanding of the universe is rooted in a cosmological model known as LCDM. The CDM stands for cold dark matter, where most of the matter in the universe isn't stars and planets, but a strange form of matter that ...

Research sheds surprising new light on evolution of plant kingdom

A new study has uncovered intriguing insights into the evolution of plant biology, effectively rewriting the history of how plants evolved over the past billion years.

Hunting for supermassive black holes in the early universe

Supermassive black holes (SMBHs)—black holes with masses exceeding a million times that of the sun—are known to prevail in the universe today. However, it is not clear yet when, where, and how they formed during the 13.8 ...

How old is the universe exactly? A new theory suggests that it's been around for twice as long as believed

Early universe observations by the James Webb Space Telescope (JWST) cannot be explained by current cosmological models. These models estimate the universe to be 13.8 billion years in age, based on the big-bang expanding ...

Searching for the universe's missing teenage pictures

Astrophysicists can use measurements of the cosmic microwave background, radiation formed 380,000 years after the Big Bang, to understand what the universe was like in its infancy. And by observing light emitted from galaxies ...

Astronomers confirm Maisie's galaxy is among earliest ever observed

Thanks to the James Webb Space Telescope, astronomers racing to find some of the earliest galaxies ever glimpsed have now confirmed that a galaxy first detected last summer is in fact among the earliest ever found. The findings ...

Looking back toward cosmic dawn—astronomers confirm the faintest galaxy ever seen

The universe we live in is a transparent one, where light from stars and galaxies shines bright against a clear, dark backdrop. But this wasn't always the case—in its early years, the universe was filled with a fog of hydrogen ...

Webb telescope reveals colors of Earendel, most distant star ever detected

Detecting extremely distant stars, or those closest in time to the big bang, can provide insights into the first few chapters of the history of our universe. In 2022, the Hubble Space Telescope broke its own record, and spotted ...

Measuring helium in distant galaxies may give physicists insight into why the universe exists

When theoretical physicists like myself say that we're studying why the universe exists, we sound like philosophers. But new data collected by researchers using Japan's Subaru telescope has revealed insights into that very ...
