An anti-universe running backwards in time could explain dark matter and cosmic inflation. A wild new theory suggests there may be another “anti-universe,” running backward in time prior to the Big Bang. The idea assumes that the early universe was small, hot and dense —...

Two galaxies colliding 275 million light years away from the sun have been captured by the Hubble Space Telescope in a new image revealing signs of intense star formation about to happen. Astronomers use a single name for the pair of galaxies, IC 1623, as...

An explosion of galactic fireworks is enabling astronomers to peer into the secrets of starbirth. A team of international scientists spread across four continents has assembled an enormous collection of data examining galaxies in multiple wavelengths, with each wavelength revealing different parts of each stellar...

All matter in the universe — no matter how big, small, young or old — is made up of atoms. Each of these building blocks consists of a positively charged nucleus, made up of protons and neutrons, and negatively charged orbiting electrons. The number of...

Why is the universe the way it is? Over the years, scientists have explored many ideas to explain our cosmos and its future. Here are some of the strangest ideas, from a braneworld scenario that involves the universe floating in a higher dimensional space, to...

Imagine a universe where you could point a spaceship in one direction and eventually return to where you started. If our universe were a finite donut, then such movements would be possible and physicists could potentially measure its size. “We could say: Now we know...

Tendrils of galaxies up to hundreds of millions of light-years long may be the largest spinning objects in the universe, a new study finds. Celestial bodies often spin, from planets to stars to galaxies. However, giant clusters of galaxies often spin very slowly, if at...

How old is our universe? That’s one of humanity’s oldest and most fundamental questions. Now, astronomers using the Atacama Cosmology Telescope (ACT), high in the Andes of northern Chile, have announced a new measurement of the cosmic background radiation, our universe’s oldest light, discovered in...

Ashley Spindler, Research Fellow, Astrophysics, University of Hertfordshire Astronomy is all about data. The universe is getting bigger and so too is the amount of...

Researchers have used the latest wireless technology to develop a new radio receiver for astronomy. The receiver is capable of capturing radio waves at frequencies over a range several times wider than conventional ones, and can detect radio waves emitted by many types of molecules...
