The Fate of a Dark Matter Theory Hinges on These Unidentified X-Rays

Despite decades of searching, no one has yet cracked the mystery of dark matter. One hypothesis to explain it relies on strange x-rays emanating from distant galaxies and galaxy clusters, but a new paper appears to rule out dark matter as producing these mysterious x-rays. Read More >>

Nearby Gas Clouds Actually Form Behemoth Structure That Might Be the Milky Way’s Arm, Study Finds

Astronomers have discovered that many of the star-forming regions we see in the sky actually seem to form an undulating, 8,800-light-year-long wave containing 3 million solar masses’ worth of gas that could make up our local arm of the Milky Way galaxy. Read More >>

Astronomers Have Stumbled Upon One of the Most Ancient Stars in the Universe

A tiny star located about 1,590 light-years from Earth could be as old as 13.53 billion years, making it one of the most ancient stars ever discovered. Read More >>

A Vast and Spooky Void Is Influencing the Milky Way

“The void” is more than a metaphor for gnawing existential pain. In fact, new research from an international team of scientists suggests that a huge void outside our extragalactic neighbourhood could be impacting the way our galaxy — and others around it — move. Read More >>

This Is the Most Detailed Hydrogen Map of the Milky Way Ever Created 

Using two of the world’s largest configurable telescopes, scientists have created the most detailed map yet of hydrogen atoms in the Milky Way. Read More >>

Photos of These Bolivian Salt Flats Perfectly Reflect the Night Sky

Since finding a perfectly dark sky is rare in our electrically-powered world, we at Gizmodo like to highlight the areas that still remain and the photography projects that explore them. This week’s photo series comes from the Altiplano salt flats (Salar de Uyuni) in Bolivia, where a team journeyed to the site and captured some amazing images. Read More >>

Astronomers Have Discovered the Most Desolate Place in the Milky Way

An international team of astronomers has discovered a huge expanse of space near the centre of the Milky Way that’s devoid of young stars. This stellar desert extends for 8,000 light-years from the galactic core — and it hasn’t produced new stars for hundreds of millions of years. Read More >>

A Third of the World’s Human Beings Can’t See the Milky Way

Our world is getting brighter, as we turn more and more lights on across the planet. But all that light shining from the ground makes it harder to see the lights shining from the sky. It’s now gotten so bad that the Milky Way is almost impossible to see in most of the western world. Read More >>

A Giant Galaxy Orbiting Our Own Just Appeared Out of Nowhere

Researchers scanning the skies just got a big surprise. They spotted a humongous galaxy orbiting our own, where none had been seen before. It appeared, seemingly, out of nowhere. Read More >>

These Newly Discovered “Super Galaxies” Are the Biggest and Brightest Ever Seen

Looking at these spiral galaxies glowing brightly against the darkness, it’s hard to imagine that they could be so easily missed — but they were right up until now, when an astronomical survey catalogued them as equal to the biggest and brightest galaxies ever seen. Read More >>

Researchers Just Discovered Hundreds of Galaxies Hidden Behind the Milky Way

Astronomers just uncovered hundreds of hidden galaxies a mere 250 light years away — well within our own galactic neighbourhood. But how did they stay unknown for so long? The fault isn’t with them, it’s with our own Milky Way. Read More >>
