Massive stars lit up the early universe

After the Big Bang, it took several hundred million years for all the hydrogen and helium and some other gases floating around to start to coalesce into the first stars to light up the universe. New research shows these ancient suns would have clustered together to form extraordinarily bright groupings of stars. Read More

Most comprehensive map of the universe yet could pinpoint dark matter

Astrophysicists from the University of Waterloo have compiled the most comprehensive 3D map of our cosmic surroundings to date. The map describes how ordinary matter is distributed in space up to a distance of about a billion light-years away from us. This survey will help scientists better understand the distribution of dark matter and explain why, to some extent, galaxies are moving erratically with respect to us.Read More

Dark matter may not be completely dark at all

New studies by astronomers are slowly throwing some light on dark matter, the invisible and mysterious stuff that scientists believe makes up much of the universe. For the first time, astronomers believe they've observed the interactions of dark matter via a factor other than the force of gravity.Read More

Astronomers discover supernova subset which could allow for more acurate galactic measurements

NASA astronomers may have found a way to take more precise measurements of the distances between galaxies. Currently, astronomers use a certain type of supernova, known as a Type la supernova, to gauge the distances between galaxies and from this, the rate at which the universe is expanding. The reason that this particular breed of supernova is singled out for this purpose, is that when they explode, they give out a very similar amount of light.Read More

ESO's MUSE instrument grants astronomers a 3D map of Hubble's Deep Field South region

ESO's Multi Unit Spectroscopic Explorer (MUSE) instrument, which is mounted on the Very Large Telescope based in the Paranal Observatory, Chile, has been focusing in on a tiny patch in the night sky previously featured in Hubble's Deep Field South image (HDF-S). After only 27 hours of continuous observation, the cutting edge instrument has captured detailed measurements of more galaxies with more detail than ever before. Read More

New Planck map begins to unlock the secrets of the early universe

ESA's Planck mission is yielding some surprising findings along with a beautiful new map of the Milky Way that breaks down some of the key elements of our galaxy. The telescope spent four years studying the cosmic microwave background radiation (CMB), a relic from the birth of the universe. The resulting data from this endeavor is now helping us refine how we measure matter, how we understand dark matter and generally just unraveling the secrets of the universe.Read More

Earth-like planets in Milky Way hint at 'possibility of ancient life'

A team of scientists has found what they claim is the oldest Earth-sized planet in the Milky Way, hinting at the possibility of ancient life elsewhere in our galaxy. Located about 117 light years from us in the constellation Lyra, the star KOI-3158 is estimated to be 11.2 billion years old, give or take 900 million years or so. For some perspective, our own sun and solar system is believed to be less than 5 billion years old. Read More
