It May Not Feel Like Anything To Be an Alien by Susan Schneider

Humans are probably not the greatest intelligences in the universe. Earth is a relatively young planet and the oldest civilizations could be billions of years older than us. But even on Earth, Homo sapiens may not be the most intelligent species for that much longer.

Software Error Implicated in Crash of Mars Lander by George Dvorsky

Researchers with the ExoMars mission are pointing to a potential computing glitch as the cause of last week’s crash of the Schiaparelli lander. The challenge now will be to isolate and correct the error in hopes of preventing a repeat in 2020, when mission planners aim to land a much larger rover on the Red Planet.

Extended Space Travel Could Cause Irreversible Back Damage by George Dvorsky

New research shows that astronauts who return from extended missions in space experience a significant weakening of their spinal muscles. Disturbingly, their back muscles don’t return to normal even after several weeks back on Earth.

Our Sun’s Quirky Tilt Means Planet Nine Might Actually Exist by George Dvorsky

New research links the odd and unexplained six-degree tilt of our Sun to an undiscovered planet in the outer reaches of our solar system. It’s even more evidence that planet Nine is for real.

How the Universe Could Annihilate Itself at the Speed of Light by George Dvorsky

Time now for a very cute video about a rather terrible prospect—the very grim possibility of the universe spawning a lethal bubble of pure vacuum that expands in all directions at the speed of light.

Astronomers Spot a Massive Black Hole That’s Gone Rogue by George Dvorsky

Using the Chandra X-ray Observatory, astronomers have found evidence of a “wandering” black hole on the outskirts of a distant galaxy. It’s too far away to cause us any trouble, but the discovery of this homeless ball of gravitational despair affirms a long standing theory about the existence of such objects.

The Nearest Earth-Like Planet Outside Our Solar System Could Be a Water World by George Dvorsky

At a distance of 4.2 light years, Proxima b is the closest potentially habitable Earth-like planet outside our solar system. New research suggests this distant orb could be completely covered in water. So when do we go?

All the Incredible Things We Learned From Our First Trip to a Comet by George Dvorsky

The historic Rosetta mission has finally come to an end. Over the past two years, the probe’s many instruments have scanned virtually every nook and cranny of this weirdly shaped rock, unleashing a treasure trove of new information about comets in general, and 67P/Churyumov–Gerasimenko in particular.

Space Exploration, Alien Life, and the Future of Humanity by Phil Torres

Less than a month ago, scientists confirmed the existence of a rocky planet roughly 1.3 times the mass of Earth named “Proxima b.” Although it orbits its star, Proxima Centauri, at about 5 percent the distance that currently separates Earth and our sun, Proxima Centauri is a red dwarf that is much less hot and luminous than our star.
