Kepler has discovered the most Earth-like planet yet

The NASA's Kepler Space Telescope team have discovered the first Earth-size planet orbiting a star in the "habitable zone". The habitable zone, also known as the "Goldilock zone", is the area around a start where...

Are there cows on Mars?

Obviously there are no cows on Mars but NASA’s Mars Curiosity Rover detected an increase of methane in the atmosphere and organic molecules from the soil during one of its drilling sessions. The findings were...

The Universe’s composition is the same everywhere

Finding out if there is life in the Universe is far from easy and even the preliminary steps are full of uncertainties. Planetary scientists don’t completely agree on what ingredients make a planet habitable,...

A Dance of Black Holes

When galaxies collide, the supermassive black holes (SMBH) at their centre merge after a long spiralling dance around each other. Several studies have been conducted to underpin everything that happens from the beginning of...

Is Saturn forming a new Moon?

Exactly one year ago, astronomer Carl Murray a scientist from Queen Mary University of London discovered a curious disturbance in the A ring of Saturn. Analysing the data of the Cassini probe which was...

The Very Hungry Supermassive Black Hole

We all get the munchies, but when you're a supermassive black hole (SMBH) your hunger might have dire consequences. And just like that an SMBH has outgrown its galaxy and jumped to the top of the heavyweight objects in the universe. About 12 billion light years from us, there is a galaxy called CID-947. It has a mass similar to our own Milky Way (about 1000 billion times the mass of the Sun) and it was only remarkable because it had an active galactic nucleus (AGN, i.e. an accreting SMBH).
