Dell and HP are two of the biggest laptop brands for good reason. They both make plenty of great PCs, and whether you’re buying a laptop for school, work, gaming, everyday productivity ...

The universe really seems to be expanding fast. Too fast, even. A new measurement confirms what previous—and highly debated—results had shown: The universe is expanding faster than predicted ...

So, while water was rare in the early universe, it is relatively common now. But a new study suggests that isn't the case. Astronomers categorize stars into populations depending on their age and ...

For example, we do now know that habitable environments are very common in the universe. It is reasonable to generalize from here to a truly gargantuan number of habitable environments across the ...

Dark matter can't be too heavy or it might break our best model of the universe, new research suggests. We have an abundance of evidence that something fishy is happening in the universe.

The Universe really seems to be expanding fast. Too fast, even. A new measurement confirms what previous -- and highly debated -- results had shown: The Universe is expanding faster than predicted ...

New research suggests that dark energy isn't needed to explain the acceleration in the expansion of the universe — instead suggesting giant voids in space are creating an illusion. When you ...

What is the structure of our physical reality? Physicists have long imagined space and time interweaving into “space-time”, the metaphorical fabric that underlies the cosmos. But there may be ...

A Yale-led team of astronomers has detected an intensely brightening and dimming quasar that may help explain how some objects in the early universe grew at a highly accelerated rate. The discovery, ...

The Samsung Galaxy S25 Ultra arrives with only modest hardware improvements but a new universe of possibilities within ...

Astronomers have been confounded by recent evidence that the universe expanded at different rates throughout its life. New findings risk turning the tension into a crisis, scientists say.
