Astronomy is increasingly code-heavy and focused on in-house development. Given the huge amounts of data generated with every night of telescope observations, it is, unsurprisingly, one of the first ...

In this video, we explore the vastness of the universe and attempt to quantify its size. We delve into the concepts of cosmic ...

Observations show the universe appears flat, yet its true size and global shape beyond the observable horizon may remain forever unknown.

Here’s what you’ll learn when you read this story: A new paper adjusts an equation that defines our universe in response to recent new data. The cosmological constant, which describes how our universe ...

The surface of Earth is finite. We can measure it. If it was expanding, then its size would grow with time. And once again, good ol' Earth helps us understand what the universe might be doing beyond ...

Andromeda and the Milky Way merge. NASA; ESA; Z. Levay and R. van der Marel, STScI; T. Hallas; and A. Mellinger Share Curious Kids is a series for children of all ages. If you have a question you’d ...

Astrophysicists have presumed for nearly a century that the universe will just keep expanding for all eternity, driven by an invisible force called dark energy. But new data suggest that this is ...

A new study has estimated the universe’s possible age by using precise data on stars.

Imagine we had somehow filmed the whole history of the universe and you could play the movie in reverse. It would start off much as things stand today: a vast and elegant web of galaxies and nebulae.
