IF EARTH’S ORBIT IS SO CROWDED, WHY DON’T WE SEE SPACE JUNK IN PHOTOS OF THE EARTH?

by Mary Beth Griggs, Popular Science

IT’S A MATTER OF PERSPECTIVE

Sometimes, when we post a cool picture of the Earth taken from space, Popular Science gets questions about why, if there’s so much garbage in space, we don’t see an orbital landfill circling our planet in pictures of the Earth. Continue reading IF EARTH’S ORBIT IS SO CROWDED, WHY DON’T WE SEE SPACE JUNK IN PHOTOS OF THE EARTH?

NASA thinks the first alien life we discover is going to look nothing like what most people expect

by Keegan Larwin and Jessica Orwig, Business Insider

When we think of our first contact with alien life, many people imagine a small green humanoid in a flying saucer. The reality will be much different. NASA’s Chief Scientist, Ellen Stofan, explains what we should expect when we do discover extraterrestrial life.

Scientists discovered something ‘shocking’ that could rewrite a key part of human evolution

by Gene Kim and Jessica Orwig, Business Insider

Human hands are capable of performing incredibly complex movements like no other parts of the body. But it’s been a long-term mystery of how they evolved into their current form. A group of researchers — Tetsuya Nakamura, Andrew R. Gehrke, Justin Lemberg, Julie Szymaszek, and Neil H. Shubin — unveiled a new study that shows evidence of where human hands might have come from.

In not-too-distant future, brain hackers could steal your deepest secrets

by Dan Goodin, ars TECHNICA

Religious beliefs, political leanings, and medical conditions are up for grabs

In the beginning, people hacked phones. In the decades to follow, hackers turned to computers, smartphones, Internet-connected security cameras, and other so-called Internet of things devices. The next frontier may be your brain, which is a lot easier to hack than most people think. Continue reading In not-too-distant future, brain hackers could steal your deepest secrets

A new material to unearth mysteries of magnetic fields

by William Weir, PHYS.ORG

Journeying to the center of the Earth, a la Jules Verne, won’t be happening anytime soon. A new material made from a liquid metal and magnetic particles, however, could make it much easier for researchers to recreate the powerful forces at the planet’s core. Continue reading A new material to unearth mysteries of magnetic fields

THE MILKY WAY IS 392 DECILLION TIMES MORE MASSIVE THAN THE HEAVIEST THING WE’VE EVER WEIGHED

by Derrick Rossignol, Nerdist

The universe is so unfathomably huge that our tiny human brains can barely imagine just how big it really is out there. Case in point, a paper recently published in the Astrophysics Journal estimates that the mass of the Milky Way galaxy is 9.5 x 10^41 kilograms — 4.8 x 10^11 times the mass of the sun. That sounds wild, but can those impossibly gigantic numbers mean anything to us? Continue reading THE MILKY WAY IS 392 DECILLION TIMES MORE MASSIVE THAN THE HEAVIEST THING WE’VE EVER WEIGHED

An unexplained ‘void’ appears to be pushing the Milky Way through the Universe at 2 million km/h

by Bec Crew, Science Alert

We’re fleeing from a mysterious ‘dead zone’

You can’t feel it, but our planet is orbiting the Sun at speeds of roughly 100,000 km/h (62,000 mph), and something is making our Milky Way galaxy move through the Universe at more than 2 million km/h (1.2 million mph). That’s 630 km per second, and now scientists might have finally figured out why.  Continue reading An unexplained ‘void’ appears to be pushing the Milky Way through the Universe at 2 million km/h

Solar wind is blasting Earth’s oxygen onto the surface of the Moon

by Peter Dockrill, Science Alert

Seeding the Moon with the ingredients of life

We all know that there’s no air to breathe on the Moon, but new evidence suggests that the lunar surface is continually being showered by oxygen escaping Earth – and may have been for billions of years, since Earth’s atmosphere developed. Continue reading Solar wind is blasting Earth’s oxygen onto the surface of the Moon

This Ghastly Sack of Cells may be your Distant Ancestor

by Sarah Fecht, Popular Science

SAY HELLO TO GREAT-GREAT-GREAT-GREAT … GRANDPA

In a paper in Nature, scientists claim to have found humanity’s oldest known ancestor. This horrifying, bag-like sea creature lived about 540 million years ago and was recently dug up in China.

Technically, the oldest known fossils go way farther back, to about 3.5 billion years. But those were cyanobacteria, and although we’re related to them, those photosynthetic creatures are on a different branch of Earth’s family tree.
