As the universe expands, it feels like it must be spreading out from some initial point. But a physicist explains why that’s not how it works. Hint: space-time is involved.

The three examples the team highlighted in a new study describe supermassive black holes feasting on stars more than three times as massive as our own sun. The events, dubbed “extreme nuclear ...

It's easy to feel let down when things don't go our way, but there are bigger forces in control. Here are 11 signs the universe is actually protecting you from harm and sending you unique signals.

Space Astronomers have spotted the largest known object in the universe The Quipu superstructure is enormous, spanning 1.4 billion light years – and it could violate one of our fundamental ...

Unfortunately, several things happen all the time in the Universe, and random quantum oscillations could send the vacuum careening into its true ground state, which would come with a collection of ...

A new AI-powered algorithm has discovered over 300 polluted white dwarfs in the Milky Way that were overlooked in old telescope data.

That's because the universe is expanding and light got a head start early on, when the universe was smaller. "Now, the total size in each direction is about 46 billion light-years," Noeske said.

The universe is, by definition, all of the things that there ever could be. Edges are things that divide one region from another. But if the universe consists of all regions, there can't be an edge.

The observable universe's 46-billion-light-year radius is not a contradiction of the universe's 13.8-billion-year age because the universe itself is expanding. The speed of light limit applies to ...

Astronomers discover universe’s brightest object – a black hole devouring a sun every day The black hole with a mass roughly 17 billion times that of the Sun has set a record that may not ever ...

The newly-discovered supermassive black hole powering the quasar is not the universe's oldest, but it's pretty darn close. Nearly as old as the 13.7-billion-year-old universe itself, the object is ...
