This Distant Blue Galaxy Contains The Least Amount of Heavy Elements Ever Detected
Astronomers have discovered something unusual about a small blue galaxy located about 30 million light-years away from Earth, and the findings could offer a great opportunity to learn more about conditions in the Universe at the time of the Big...

We Could Be On The Brink Of Discovering Something Extraordinary At The Large Hadron Collider
The aim of science is to describe as best as we can the natural world around us. Hypotheses are formulated, tested, and when successful turned into theories. The theories then continue to be tested and challenged. The process doesn't stop. We push them to their limits and sometimes we can go beyond them. And we might be lucky enough to see this very soon.

Astronomers Just Measured a Black Hole, And It's 660 Million Times More Massive Than The Sun
Just because we don't have an actual picture of one yet, doesn’t mean that researchers aren’t constantly trying to figure out what the hell is going on with black holes, and it’s easy to see why. These massive objects, which commonly lie at the...

Astronomers Might Have Finally Detected Where Mysterious, Extragalactic Neutrinos Are Coming From
Just over three years ago, physicists working in Antarctica announced they'd detected the first evidence of mysterious subatomic particles, known as neutrinos , coming from outside our galaxy. It was a huge moment for astrophysics , but since then,...

Aliens Are Silent Because They're Dead, Says New Study
New research into how life might have evolved elsewhere in the Universe has thrown up a rather depressing possibility - we haven’t found any aliens yet because they’re probably already dead. The hypothesis is based on what we know about the first...

The Sun Might Have Consumed a 'Super-Earth' in Our Solar System
While scientists are frantically trying to track down the hypothetical Planet Nine that's thought to be making its unusual orbit around the Sun , there's a chance our Solar System could have once played host to an equally intriguing and mysterious...

Astronomers Have Discovered The First Star With an Almost Pure Oxygen Atmosphere
Scientists have identified a new kind of star that up until this point had only been considered hypothetically: an ancient sun that has lived so long, its outermost layer is now composed almost entirely of pure oxygen. When relatively small stars –...

Scientists Discover Molecular Oxygen on a Comet For The First Time
A halo of oxygen molecules has been found on the comet 67P/Churyumov-Gerasimenko, and the researchers behind the discovery aren’t quite sure why it’s there. But there’s a good chance the oxygen was present before or during the formation of the...

New Candidate Particles For Dark Matter Are So Dense They Are Almost Miniature Black Holes
Dark matter comprises up to five-sixths of the total matter in the universe, binding much of it together. Despite its commonality, the physical nature of dark matter, as of 2016, remains elusive, with its dramatic effects only indirectly seen.

Astronomers say they’ve found the biggest structure in the universe and they named it the BOSS
The BOSS is big. Really big. Yuuuuuge. It's an immense complex comprising more than 800 galaxies and weighing 10,000 times as much as the Milky Way.

A Five-Dimensional Black Hole Could 'Break' General Relativity, Say Physicists
If you thought regular black holes were about as weird and mysterious as space gets, think again, because for the first time, physicists have successfully simulated what would happen to black holes in a five-dimensional world, and the way they...

Is This The Largest Rocky Exoplanet That We've Ever Found?
What is the upper limit on how large a rocky planet can be? This is a contentious area in astronomy. Generally, it’s thought that above about 1.6 times the radius of Earth, a planet will become a gas giant. Anything below this is a super-Earth, and smaller still are the terrestrial planets the size of Earth, Mars, and so on.

Earth Is Made Up of Two Planets Fused Together, New Research Suggests
Astronomers investigating how the Moon formed have found evidence that it was produced after a small planet smashed headfirst into Earth around 4.5 billion years ago. And research suggests that this collision was so violent that the 'planetary...

Pluto Is Covered in Frozen Water. Lots of Frozen Water
This false-color image, derived from observations in infrared light by the Ralph/Linear Etalon Imaging Spectral Array (LEISA) instrument, shows where the spectral features of water ice are abundant on Pluto’s surface. It is based on two LEISA scans of Pluto obtained on July 14, 2015, from a range of about 67,000 miles.

Scientists Find Most Powerful Known Supernova
Scientists Find Most Powerful Known Supernova - Details have been released of the most powerful supernova ever recorded. Astronomers hope the study of ASASSN-15lh will advance our understanding of super-luminous supernovae (SLSNs), astonishing explosions that manage to exceed even regular supernovae in the quantity of energy released in a single enormous burst.

Largest Age Map Of The Milky Way Confirms It Formed Inside-Out
Understanding how galaxies form is still an open question in astronomy. Researchers think that galaxies grow in a bottom-up paradigm, with smaller objects forming first and then getting progressively bigger. And astronomers have now discovered the most conclusive evidence yet that this is the case.

Scientist Claims To Have Figured Out What The Mysterious "Wow!" Signal Was
Almost 40 years ago, we received a mysterious signal from space. The signal lasted for 72 seconds and it was so unusual that it was dubbed the Wow! Signal, owing to the word scrawled by its discoverer. It has been puzzling scientists ever since. Several explanations from unusual phenomena, transient events, and even aliens have been put forward. Now a Florida professor might have found a different explanation.
