Are we really alone in this vast universe?
A question NASA’s SETI (Search for Extra-Terrestrial Intelligence) has been desperately trying to answer for decades now. Most recently, NASA found a solar system of seven planets, about 40 light years away, which may, in fact, be capable of supporting life. They believe that this system has three planets with precisely the right conditions for the existence of water and in turn,...

Scientists using NASA's Hubble space telescope have discovered a white dwarf star whose atmosphere is rich in materials that are the basic building blocks for life - carbon, nitrogen, as well as oxygen and hydrogen, the components of water.
The white dwarf is approximately 200 light years from the Earth and is located in the constellation Bootes, said the study.
White dwarf stars are dense, burned-out remnants of normal...

A small but distinctive signal in X-rays from the Milky Way could be key to proving the existence of dark matter.
That is the claim of US scientists who analysed the energy spectrum of X-rays gathered by Nasa's Chandra satellite.
They found more X-ray photons with a particular energy than would be expected if they were produced only by familiar processes.
Those photons could in fact have been generated by the decay of dark...

This protective field acts as a barrier that protects the Earth from harmful cosmic radiation, while protecting our planet from solar waves go directly toward Earth.
Scientists at MIT have found that there is an invisible field that protects our planet. This mysterious invisible field sounds like something from a science fiction movie.
It prevents harmful cosmic radiation that enters our atmosphere and was first noticed by two NASA...

If you only see one astronomical event this year, make it the November supermoon, when the Moon will be the closest to Earth it’s been since January 1948.
During the event, which will happen on the eve of November 14, the Moon will appear up to 14 percent bigger and 30 percent brighter than an average full moon. This is the closest the Moon will get to Earth until 25 November 2034, so you really don’t want to miss this...

Of all the chemical reactions we've covered within the past few months, the one filmed below probaby takes the prize for coolest looking and possibly scariest. After the pile of reactants is lit, it begins to look like tentacles are crawling out of a portal to Hell.
In reality, what's depicted in the video below is actually two reactions: the decomposition of ammonium dichromate and the combustion reaction of mercury (II)...

There are plenty of ways Earth could go. It could smash into another planet, be swallowed by a black hole, or get pummeled to death by asteroids. There's really no way to tell which doomsday scenario will be the cause of our planet's demise.
But one thing is for sure — even if Earth spends the rest of its eons escaping alien attacks, dodging space rocks, and avoiding a nuclear apocalypse, there will come a day when our own...

The Israeli-Palestinian conflict has left almost 90 percent of the water supply unfit for people to drink. Fayez al-Hindi has devised a homemade water desalinization setup that is helping to solve the water crisis, though, as some Gaza residents face running out of water in mere months. It runs on solar power and a little ingenuity.
Three years of jets bombing the Gaza strip have left the territory’s water infrastructure extremely...

Under the imperfect but groundbreaking Paris agreement, now ratified by the world’s two largest carbon emitters, it’s hoped that the world will not warm by more than 2°C (3.6°F) by 2100. Sadly, we have registered so many high-temperature records this year alone that it’s looking doubtful that this will be achieved – and it appears that the most ominous record has just been broken.
According to data provided...

She was just playing around in the lab when she figured everything out!
There’s an old saying that luck happens when preparation meets opportunity. There’s no better example of that than a recent discovery at the University of California by doctoral student Mya Le Thai. She was simply playing around their school’s lab when she discovered a scientific breakthrough!
A team of researchers at UCI had been...

30 days without sleep. They weren't humans anymore. Why do something so..barbaric?
#5 The experiment
In the late 1940's, five prisoners were chosen to take part in an experiment involving sleep deprivation. That would be acheived by using small doses of an experimental gas that could supposedly eliminate the necessity of sleep in humans. The subjects were given micriphones to communicate with the researchers, and kept in...

Whenever NASA announces an upcoming announcement, it normally sends Internet predictions up the wazoo. And this latest one is probably going to be no different, although it’s probably not aliens. Sorry.
On Monday, September 26, at 2pm EDT (7pm BST), NASA is going to reveal “surprising evidence” of activity on Jupiter’s moon Europa. In a short statement, NASA said this evidence “may be related to the presence...

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.

Last week, the world was shocked when a rocket from Elon Musk's famed private space flight company SpaceX exploded on the launch pad at Cape Canaveral during a test. The explosion (which was technically a fast-moving fire, according to Musk) also destroyed the rocket's most precious cargo, Facebook's first satellite.
While the exact cause of the explosion is still being investigated, hawk-eyed conspiracy theorists have quite a...

Astronomers have found a galaxy that they think might be made of 99.99 percent dark matter. Called Dragonfly 44, it is located more than 300 million light-years from Earth in the Coma constellation, but is strangely devoid of “normal” matter – leading astronomers to their conclusion.
The galaxy is described in a new paper published in the Astrophysical Journal Letters. It has a similar mass to our own Milky Way galaxy,...
