In order for humanity to survive into the distant future, we need to visit and learn how to survive on other worlds, according to NASA chief Charles Bolden.
Last week, scientists announced the discovery of Kepler-186f, a planet 492 light years away in the Cygnus constellation. Kepler-186f is special because it marks the first planet almost exactly the same size as Earth orbiting in the “habitable zone,” the distance from a star in which we might expect liquid water—and perhaps life.
The sun will look like a ring of fire above some remote parts of the world next Tuesday (April 29) during a solar eclipse, but most people around the world won't get a chance to see it.
There are dozens upon dozens of moons in the Solar System, ranging from airless worlds like Earth's Moon to those with an atmosphere (most notably, Saturn's Titan). Jupiter and Saturn have many moons each, and even Mars has a couple of small asteroid-like ones. But what about Venus, the planet that for a while, astronomers thought about as Earth's twin? .
When large asteroids or comets strike the Earth — as they have countless times throughout our planet’s history — the energy released in the event creates an enormous amount of heat, enough to briefly melt rock and soil at the impact site. That molten material quickly cools, trapping organic material and bits of plants and preserving them inside fragments of glass for tens of thousands, even millions of years.
Death is the one certainty in life – a pioneering analysis of blood from one of the world's oldest and healthiest women has given clues to why it happens.
Could preventing the brain shrinkage associated with depression be as simple as blocking a protein?
Fertilization takes place when an egg cell and a sperm cell recognize one another and fuse to form an embryo.
In some parts of Ethiopia, finding potable water is a six-hour journey.
Researchers in South Korea have devised a way to harness the motion of water, including from raindrops or from a flushing toilet, as a sustainable energy source.
Humans are good at making things that are one color. But if you want to really blend into your surroundings, it would be best to have a material that can change its appearance based on its surroundings--like a chameleon. University of Michigan researchers have created a material imbued with a special type of crystal that can change its shape and color when different wavelengths of light are shone on it, that could be used in the future to create active camouflage.
Let’s face it, from trivia to teaching, computers are doing things we thought were uniquely human — and doing them better. Now, facial recognition, a skill humans once dominated, has a new champion. Computer scientists have developed a facial recognition algorithm that, for the first time, outperforms humans’ own abilities.
While the world has been deciding who governs the internet, Brazil has been busy establishing internet rules of its own -- and they may just set an example for everyone else. The country has passed a bill of rights that goes some length towards protecting net neutrality and privacy.

Lowland South America, including the Amazon Basin, harbors most of the last indigenous societies that have limited contact with the outside world. Studying these tribes, located deep within Amazonian rainforests, gives scientists a glimpse at what tribal cultures may have been like before the arrival of Europeans.
A treasure trove of Coast Miwok life dating back 4,500 years - older than King Tut's tomb - was discovered in Marin County and then destroyed to make way for multimillion-dollar homes, archaeologists told The Chronicle this week.
Scientists have discovered rare, fossilised embryos of what is thought to be a previously unknown animal.
Paleontologists have described a new species of assassin fly found preserved in two pieces of 100-million-year-old Burmese amber.
The authenticity of the "Gospel of Jesus's Wife" has been debated since the papyrus was revealed in 2012. Now, new information uncovered by Live Science raises doubts about the origins of the scrap of papyrus.
