Galaxy Zoo Hunters Help Discover Rare ‘Green Peas’ Galaxies

The Green Peas stuck out because of their small size and green color compared to the more common galaxies

A team of astronomers has discovered a group of rare galaxies called the “Green Peas” with the help of citizen scientists working through an online project called Galaxy Zoo. The finding could lend unique insights into how galaxies form stars in the early universe.

Could Alien Life Be Thriving On Saturn’s Frozen Moon?

Could There Be Alien Life Be Thriving On Saturn’s Frozen Moon?

 The surface of Saturn’s moon Enceladus shows evidence of ongoing geological activity 

Alien life could have evolved on one of Saturn’s moons, scientists say.

They have found evidence that seas may lie beneath the frozen surface of Enceladus  – the planet’s sixth biggest moon.

The Mysterious Mima Mounds

The Mysterious Mima Mounds 

We don’t know what they are, where they came from, or what caused them

Scientists love a mystery. Biologists used to have the human genome, but now they have the structure of protein. Physics used to have cosmic rays, but now they have the God particle. Astronomers used to have black holes, but now they have dark matter. (Pics)

Does A Twin Earth Exist?

Does A Twin Earth Exist?

Artist’s conception shows a hypothetical twin Earth orbiting a Sun-like star.

Does a twin Earth exist somewhere in our galaxy? Astronomers are getting closer and closer to finding an Earth-sized planet in an Earth-like orbit. NASA’s Kepler spacecraft just launched to find such worlds. Once the search succeeds, the next questions driving research will be: Is that planet habitable? Does it have an Earth-like atmosphere? Answering those questions will not be easy.

1. Large Hadron Collider

Good news! The Large Hadron Collider (LHC) – the massive particle accelerator straddling the Swiss-French border – didn’t destroy the world! The bad news: The contraption didn’t really work either. In September, the 17-mile collider was switched on for the first time, putting to rest the febrile webchatter that the machine would create an artificial black hole capable of swallowing the planet or at least a sizeable piece of Europe – a bad day no matter what. No lucid observer ever thought that would really happen, but what they did expect was that the LHC would operate as advertised, recreating conditions not seen since instants after the Big Bang and giving physicists a peek into those long-vanished moments. Things looked good at first, until a helium leak caused the collider to shut down after less than two weeks. Repairs are underway and the particles should begin spinning again sometime in June.

Scientists Directly Observe Three Distant Planets

Scientists Directly Observe Three Distant Planets 

 The Hubble Space Telescope captured a fuzzy image of the planet, known as Fomalhaut b, which is no more than a white speck in the dust ring that surrounds the star.

A little more of the universe has been pried out of the shadows. Two groups of astronomers have taken the first pictures of what they say – and other astronomers agree – are most likely planets going around other stars.
