Where do the hydrogen and oxygen that make up the earth’s water come from?
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.
New mathematics have shown that lines of energy can be used to describe the universe.

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.
Diligence, technological progress and a little luck have together solved a 20 year mystery of the cosmos.
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.
No one knows what kicked off the Big Bang that eventually allowed the stars to begin forming.

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.
Dark matter and gas in the universe. There may be more dark matter than we think.
A study has suggested that the universe is curved like a sphere rather than flat, which may unleash a major crisis in cosmology.
Dark sky sites can inspire new generations of stargazers, but a better long-term solution would be connecting people with the night sky where they live.

Maps of the long filaments of gas that hold the universe together may one day help us trace and unveil 'dark matter'.
Dr. Burbidge is presented with the “Woman of the Year” award in 1976, while professor at UC San Diego.
In an age when women were rarely allowed in observatories, Margaret Burbidge changed how we saw the stars.
‘Unknown Pleasures’ as you’ve never seen it before…
When you look at the squiggly lines on Joy Division's famous album cover, you're seeing a record of lightning in outer space.
Gravity helps stars to form.

Gravity exists because the universe is full of 'stuff' – here's how it came to be.
The Milky Way stretches across the sky near the Hungarian border village of Tachty in Slovakia.
The diameter of the Milky Way is a billion billion kilometres.
It would be nice to blast dangerous nuclear waste far away from Earth, or into the Sun where it won’t cause any harm. However, it’s not as simple as it sounds.
At the end of the day, the problem is that no-one on Earth wants nuclear waste stored near them, and it's not safe or cost-effective to blast it into space.
The South Pole Telescope and BICEP telescopes (pictured above) may discover clues that could teach us if there was something else ‘before’ the Big Bang.

Long ago in the distant past, our entire Universe was microscopic – just like an atom – and obeyed completely different rules of cause and effect.

Our brain cells do look a lot like a map of the universe – but that doesn't mean they're the same thing.
Captured: approximately 15,000 galaxies (12,000 of which are star-forming) widely distributed in time and space.

Astronomers are voting to rename one of the laws of physics. The voting may have far-reaching effects leading to renaming of other laws and giving 'forgotten' scientists due credit.
A podcast all about nothing. From the importance of doing nothing to the ill-effects of time spent in solitary confinement and what nothing means in space.
Nearly 50 years since the first man walked on the moon, our morals are still stranded on Earth.
About a century ago, we didn’t even know that galaxies existed.
Mai Lam/The Conversation NY-BD-CC
Pretty much as soon as we understood what galaxies were, we realised they are all moving away from each other. And the ones that are further away are moving faster. In short, the universe is expanding.
