The James Webb Space Telescope is set to launch into orbit in December 2021. Its mission is to search for the first light to ever shine in the universe.
Scientists have a good estimate on the staggering number of stars in the universe.
Gravity, mass and centrifugal force all contribute to the final shape of a planet.
Technology is allowing astronomers to study and analyse galaxies in far more detail than was previously possible.
The universe has a finite age — 13.8 billion years to be exact. So if it had a beginning, why is it so difficult to say for sure whether it will have an end?
Billions of galaxies are in the universe, with billions of stars in every galaxy. Could billions of planets be out there too?
Machine learning is helping astronomers unravel the vast amounts of data being collected.
A different interpretation of time might explain why people see their whole lives replayed to them in a split second.
A recent study shows that the Earth’s water could come directly from the oxygen and hydrogen present in the rocks that formed it, and not from a late supply by asteroids.
Thanks to the discovery of five twinkling galaxies in a rare alignment, astronomers have been able to calculate — for the first time — the properties and geometry of an invisible gas cloud in space.
Some of the baby radio galaxies found may not be ‘babies’ at all. Rather, they may be ‘angsty teens’, rapidly growing into adults much faster than researchers had anticipated.
Based on what we currently know about the density of giant radio galaxies in the sky, the probability of finding two of them in this region is extremely small.
Field theory describes the universe as energy flowing along unending lines. With this perspective, it is possible to define a new fundamental building block of matter.
Dark energy is probably a sea of constant energy in empty space itself, according to new research.
Cosmologists had only been able to find half the matter that should exist in the universe. With the discovery of a new astronomical phenomenon and new telescopes, researchers just found the rest.
The term ‘Big Bang’ might make you think of a massive explosion. Put the thought out of your head. Rather than an explosion, it was the start of everything in the universe.
Thirty years ago the Hubble Space Telescope began snapping photos of distant stars, providing a time machine that has taken astronomers back to when the universe was less than a billion years old.
New research using the Hubble Space Telescope reveals that galaxies may be forming at faster rates than previously believed.
A study has suggested that the universe is curved like a sphere rather than flat, which may unleash a major crisis in cosmology.
