1. Sagittarius B2 Gas Cloud
in a giant dust cloud at the heart of the Milky Way have concluded that it would taste vaguely of raspberries.
The unanticipated discovery follows years of work by astronomers who trained their 30m radio telescope on the enormous ball of dust and gas in the hope of spotting complex molecules that are vital for life.
Finding amino acids in interstellar space is a Holy Grail for astrobiologists, as this would raise the possibility of life emerging on other planets after being seeded with the molecules.
In the latest survey, astronomers sifted through thousands of signals from Sagittarius B2, a vast dust cloud at the centre of our galaxy. While they failed to find evidence for amino acids, they did find a substance called ethyl formate, the chemical responsible for the flavour of raspberries.
2. Gliese 581c
Gliese 581C has two polar opposites and one perfect temperature in between those polar opposites, one side of the planet would melt your face off and the other would see you set in ice, but in the middle has a very earth like habitat.
3. Black Holes
No one really knows what happens if you went through a black hole but after a certain point you are unable to escape it. There are quite a few theories, a recent one is a black hole is actually a tunnel between universes—a type of wormhole. The matter the black hole attracts doesn’t collapse into a single point, as has been predicted, but rather gushes out a “white hole” at the other end of the black one, the theory goes.
4. Gravitational Lensing
A distribution of matter (such as a cluster of galaxies) between a distant source and an observer, that is capable of bending the light from the source, as it travels towards the observer. Gravitational lensing works in an analogous way and is an effect of Einstein’s theory of general relativity – simply put, mass bends light. The gravitational field of a massive object will extend far into space, and cause light rays passing close to that object (and thus through its gravitational field) to be bent and refocused somewhere else. The more massive the object, the stronger its gravitational field and hence the greater the bending of light rays – just like using denser materials to make optical lenses results in a greater amount of refraction.
5. The Diamond Planet
A planet which really does twinkle like a diamond in the sky has been discovered by scientists – its surface is littered with the precious stones.
The planet – called 55 Cancri e – has a radius double the size of Earth’s, and weighs eight times more.
Whilst Earth’s surface is covered in water and granite, the new planet is thought to be covered in diamonds and graphite.
6. Water Reservoir 12 Billion Light Years Away
The water is out in space, a place we used to think of as desolate and desert dry, but it’s turning out to be pretty lush.
Researchers found a lake of water so large that it could provide each person on Earth an entire planet’s worth of water—20,000 times over. Yes, so much water out there in space that it could supply each one of us all the water on Earth—Niagara Falls, the Pacific Ocean, the polar ice caps, the puddle in the bottom of the canoe you forgot to flip over—20,000 times over.
