Weirdest Planets

National Geographic: Weirdest Planets: With temperatures ranging from 1000 to 2000°C, gravity 15 times stronger than Earth’s, and a year that lasts just 5.6 of our days, HAT-P-2b is not a planet you’d want to visit for vacation.

The Universe - Alien Moons

The number of known moons of the outer planets have exploded in recent years. Each has it own story to tell regarding its composition, geological activity and origin.

Aliens may destroy humanity to protect
other civilisations, say scientists

Rising greenhouse emissions could tip off aliens that we are a rapidly expanding threat, warns a report

It may not rank as the most compelling reason to curb greenhouse gases, but reducing our emissions might just save humanity from a pre-emptive alien attack, scientists claim.
Watching from afar, extraterrestrial beings might view changes in Earth's atmosphere as symptomatic of a civilisation growing out of control – and take drastic action to keep us from becoming a more serious threat, the researchers explain.

Space Boat: A Nautical Mission to an Alien Sea

In 2006, while flying by Saturn’s moon Titan, the radar on NASA’s Cassini orbiter discovered seas of liquid ethane and methane on the moon’s –300ºF surface, the only bodies of liquid we know of that exist anywhere but on Earth. Some of the oily seas appeared on Cassini’s radar to be larger than Lake Superior, but visibility was poor because Titan’s atmosphere is thick and hazy.

Was Earth's moon made by 2 moons crashing?

Martin Jutzi and Erik Asphaug
This computer illustration depicts a collision between Earth’s moon and a companion moon that is 750 miles wide and about 4 percent of the lunar mass. This late, slow accretion could explain the moon's farside highlands, scientists say.
A tiny second moon may once have orbited Earth before catastrophically slamming into the other one, a titanic clash that could explain why the two sides of the surviving lunar satellite are so different from each other, a new study suggests.

Where did my consciousness come from?

THINK for a moment about a time before you were born. Where were you? Now think ahead to a time after your death. Where will you be? The brutal answer is: nowhere. Your life is a brief foray on Earth that started one day for no reason and will inevitably end.
But what a foray. Like the whole universe, your consciousness popped into existence out of nothingness and has evolved into a rich and complex entity full of wonder and mystery.
