Embark on a journey of discovery beneath the stars with this mesmerizing time-lapse of the Milky Way, where the night sky ...

Our understanding of where we fit in the universe has been transformed.

So it’s confession time: I’ve been lying to you. I’ve said on many occasions that our Milky Way galaxy has a flat disk (like ...

Astronomers know that mergers play a huge role in galaxy growth. Right now, the Milky Way is slowly consuming the Large and ...

In recent years, one of the most troubling puzzles in astrophysics has grown more urgent. Scientists have realized that the universe seems to be expanding faster than expected, throwing a wrench into ...

The mystery of galaxies in the early Universe just got even weirder. A team of astronomers has identified a giant spiral galaxy so well-formed that it already has a stable galactic bar; a long, ...

An MIT astronomy class has found three of the oldest stars in the universe lurking right outside the Milky Way. The stars, about 30,000 light-years from Earth, are in the galaxy's "halo," the cloud of ...

One of the new high-resolution simulations of the dark matter enveloping the Milky Way and its neighbour, the Andromeda galaxy. The new study shows that earlier, failed attempts to find counterparts ...

A research team led by Dr. HUANG Yang from the National Astronomical Observatories of the Chinese Academy of Sciences (NAOC) pioneered the "motion picture" method for measuring the precession rate of ...

All motion is relative. That simple fact makes tracking the motion of distant objects outside our galaxy particularly ...

To find the universe’s oldest stars, you must look for the ones with low chemical abundances and a retrograde orbit. That’s what a group of students in a class of MIT professor of physics and division ...
