The world’s largest digital survey of the visible Universe, mapping billions of stars and galaxies, has been publicly released.
Everyone has a backstory, even our own Milky Way galaxy. And much like social media, the picture is not always as pretty as it appears on the current surface, says Texas A&M University astronomer Casey Papovich.
The intriguing story of Mars’ mysterious dark streaks may have a new twist.
The streaks, known as recurring slope lineae (RSL), occur seasonally on steep, relatively warm slopes at many locations on the Red Planet.

Located in the area of Terra Meridiani, researchers have spotted three massive ‘Towers’ on the Martian Surface that are so perfectly aligned, that just as the Pyramids of Giza on Earth, these Martian towers seem to mimic the constellation of Orion.
Planet Earth is effectively defenceless in the face of a “dinosaur-killer” asteroid strike, a Nasa scientist has warned.
And the planet is overdue for an extinction-level event involving a giant space object – such as an asteroid or comet – following a number of close encounters over the last 20 years, Dr Joseph Nuth said.
Hydrogen’s antimatter counterpart has shown its true colours, and they are just what physicists ordered.

Scientists are a little bit closer to unlocking the mystery of how the rules of the quantum realm translate to the rules of the classical physics of the observable world.
Experts predict that the materials used in this research, topological insulators, will play a key role in furthering this development.
Erik Verlinde’s emergent gravity theory makes sense of the behavior of gravity without the need for the existence of a dark matter particle.
Researchers from the Leiden Observatory have studied more than 33,000 galaxies to see if Verlinde’s theory checks out.

Although the sun is our nearest star, it still hides many secrets. But it seems that one solar conundrum may have been solved and a theory originally proposed in 1905 by Albert Einstein could be at the root of it all.
Twenty years ago, solar astronomers realized that the uppermost layer of the sun rotates slower than the rest of the sun’s interior. This is odd.
Astronomers have spotted transient, transit-like dimming events of a young star named RIK-210 located some 472 light years away in the Upper Scorpius OB association. However, what puzzles the scientists is the mystery behind this dimming as it can not be caused by an eclipsing stellar or brown dwarf companion. They describe their search for plausible explanations in a paper published Dec. 12 on the arXiv pre-print server.
Just like the moon and Mercury, the largest asteroid in Earth’s solar system, Ceres, has cold pockets of perpetual darkness on its surface where researchers have now detected ice, a new study finds.

Future moon colonies could be totally tubular.
Slight variations in the moon’s gravitational tug have hinted that kilometers-wide caverns lurk beneath the lunar surface.
Researchers from the University of Waterloo have developed a method that will detect roughly 10 black holes per year, doubling the number currently known within two years, and it will likely unlock the history of black holes in a little more than a decade.
Statistical analysis of mini-spiral galaxies shows an unexpected interaction between dark matter and ordinary matter. According to the SISSA study recently published in Monthly Notices of the Royal Astronomical Society, where the relationship is obvious and cannot be explained in a trivial way within the context of the Standard Model, these objects may serve as “portals” to a completely new form of Physics which can explain phenomena like matter and dark energy.

Scientists have made the rare discovery of a planetary system with a host star similar to Earth’s sun. Especially intriguing is the star’s unusual composition, which indicates it ingested some of its planets.
If your death-from-above musings focus solely on asteroids , you need to broaden your worried mind.
Comets can also deliver a heaping helping of calamity to Earth, and scientists and policymakers alike should start taking measures to combat the threat, said Joseph Nuth, a researcher at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.
Seventy percent of Earth’s surface is covered by water, meaning if we were unfortunate enough to be struck by an enormous asteroid, it’d probably make a big splash. A team of data scientists at Los Alamos National Laboratory recently decided to model what would happen if an asteroid struck the sea. Despite the apocalyptic subject matter, the results are quite beautiful.
