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.

Are Mars’ Dark Streaks Really Evidence of Liquid Water?
20th December 2016 | space.com | Space

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.

Earth is overdue for collision with ‘dinosaur-killer’ asteroid, Nasa warns
20th December 2016 | independent.co.uk | Earth, Space

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.

This Material Could Reveal the Link Between Classical Physics and the Quantum Realm
20th December 2016 futurism.com | Space, Tech

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.

A New Theory of Gravity Just Passed its First Test. Here’s What This Means for Physics
20th December 2016 futurism.com | Space

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.

Einstein’s Theory Just Put the Brakes on the Sun’s Spin
20th December 2016 | seeker.com | Space

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 observe mysterious dimming of a young nearby star
20th December 2016 phys.org | Space

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.

Water Ice Found On Dwarf Planet Ceres, Hidden in Permanent Shadow
19th December 2016 | space.com | Space

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.

Number of known black holes expected to double in two years with new detection method
19th December 2016 phys.org | Space

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.

Unexpected interaction between dark matter and ordinary matter in mini-spiral galaxies
18th December 2016 phys.org | Space

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.

Astronomers discover dark past of planet-eating ‘Death Star’
18th December 2016 | sciencedaily.com | Space

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.

How to Stop an Incoming Comet
18th December 2016 | scientificamerican.com | Space

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.

Here’s What Would Happen If a Giant Asteroid Struck the Ocean
18th December 2016 gizmodo.com | Space

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.
