With a thick atmosphere, clouds, a rain cycle and giant lakes, Saturn’s large moon Titan is a surprisingly Earthlike place. But unlike on Earth, Titan’s surface is far too cold for liquid water – instead, Titan’s clouds, rain, and lakes consist of liquid hydrocarbons like methane and ethane (which exist as gases here on Earth). When these hydrocarbons evaporate and encounter ultraviolet radiation in Titan’s upper atmosphere, some of the molecules are broken apart and reassembled into longer hydrocarbons like ethylene and propane.
Black holes are the most exotic and awe inspiring objects in the Universe.
Take the mass of an entire star. Compress it down into an object so compact that the force of gravity defies comprehension.
We see it every day (unless you live near one of the poles, in that case you have our condolences). But how much do we actually know about? Ok, so you probably know at least a few things. It’s big, orange…wait a minute. You’re already wrong. The sun isn’t orange. And it’s not yellow either. Check out these 25 crazy facts you didn’t know about the sun and you might never look at it the same way again (hint: you should never look at the sun anyway…it’s bad for your eyes)
A new study led by Dr. René Heller from McMaster University in Canada and Dr. Jorge Zuluaga from the University of Antioquia in Columbia takes a theoretical look at habitability – exploring the key components that may make exomoons livable. While stellar and planetary heating play a large role, it’s quickly becoming clear that the magnetic environments of exomoons may be even more critical.
If humanity lasts into the far future, we’ll need lots of energy; eventually, an entire star’s worth of energy. Here’s a plan, suggested by Freeman Dyson, to harness the power of a star like our Sun.
As the possible ‘comet of the century’ approaches its date with the Sun (Nov. 28th, 2013), the chances of its break-up will increase exponentially. The comet is not on a trajectory to hit the Earth. What will happen to pieces that may break away?
NASA’s Mars rover Curiosity (AFP Photo / NASA) The rover Curiosity has discovered water in fine-grained soil on the surface of Mars, NASA confirmed Thursday in a series of papers published in the journal Science. Each cubic foot of Martian soil contains about two pints of liquid water, though the molecules are bound to […]
We all know it’s awesome, and we could watch Chris Hadfield sing all day, but do you know about the awesome science that’s being done on the International Space Station?
Using a phone to search for signs of life? Yeah, we can get behind that. One group of researchers has a system that they’ve been testing out in analog environments with the aim of (eventually, one day, they hope) it being applied, say, to other planets — such as Mars.
No time to read Stephen Hawking’s A Brief History of Time? In just two and a half minutes, Alok Jha explains why black holes are doomed to shrink into nothingness then explode with the energy of a million nuclear bombs, and rewinds to the big bang and the origin of the universeâ?
Earth’s radiation belts consist of energetic particles that are encircle the planet and are trapped by the geomagnetic field. The radiation belts usually form a two-zone structure, but last February, a team of scientists reported the surprising discovery of a previously unknown third radiation ring, which just now has been explained.
Researchers from ETH Zurich and the University of Miami, comeup with the theory that some of the largest ocean eddies are mathematically equivalent to the mysterious black holes of space.
No matter where you live on Earth, you experience seasons, as we pass from Spring to Summer to Fall to Winter, and then back to Spring again.
Why do we have variations in temperature at all? What causes the seasons?
