Astrophysicists have long suspected that some dark matter halos might exist without forming stars, but no one knew the exact mass limit where this transition occurs. A computational astrophysicist has ...

It's believed to account for roughly 85% of the universe's mass, yet no telescope or sensor on Earth has been able to track ...

According to the most widely accepted cosmological model, the first stars and galaxies began forming around 300-400 million ...

Bring the Moon and planets into closer view, spot stunning star clusters and observe distant galaxies and nebulas with your own eyes — you can even photograph your subject with a smart telescope.

We don’t know for sure, but the answer is inextricably linked to the moment when water first materialized in the cosmos — and ...

Scientists at the Harvard-Smithsonian Center for Astrophysics are leading a major part of NASA’s new SPHEREx mission to study ...

When I get stressed, I look into the night sky and allow my mind to roam the infinity of space and time. It helps to get your ...

Researchers interrogated the 'sounds' of a cluster of stars within the Milky Way, uncovering a new technique for astrophysicists to probe the universe and learn more about its evolution.

The cluster, full of more than 2,500 newborn stars that blaze blue in the Hubble image, is in a galaxy with far fewer heavy chemical substances than the Milky Way. It's mostly made of hydrogen and ...

One of the most powerful objects in the universe is a radio quasar—a spinning black hole spraying out highly energetic ...
