Dark matter is a type of matter that does not emit, absorb, or reflect light, making it invisible to telescopes.

Astronomers use many methods to determine this number, including gravitational lensing, the universe’s expansion rate, and more.

The team explores one of the greatest discoveries of modern astronomy - that our universe is expanding - and the new ...

However, the diameter of the observable universe is said to be over 900 billion light-years, right? Oh yes, the Beijing ...

In fact, the Euclid Consortium, the international group managing the European Space Agency's Euclid space telescope, just ...

What is the source of dark matter and how can astronomers identify it? This is what a recent study published in Nature Astronomy hopes to address as an int | Space ...

The Big Bang Theory remains the most accepted explanation for how the universe began. This documentary explores the science, ...

Modern cosmology reveals a universe expanding uniformly without a spatial center or edge. The Big Bang wasn't a localized ...

Astronomers using the Webb Telescope may have found a new type of object: cold, glowing black hole stars from the early ...

Some things we see in space appear to outpace light. Now we are learning to harness these bizarre optical illusions to ...

The key test passed by sPHENIX to prove it is ready to measure the properties of quark-gluon plasma is called a "standard candle" in particle physics. This isn't to be confused with Type 1a supernovas ...

The universe's matter-antimatter asymmetry, where matter significantly outweighs antimatter despite their theoretically equal creation at the Big Bang, remains a major unsolved problem in physics.
