New insight into the minor merger process

Galaxy mergers are violent interactions between galaxies and they are consider one of the fundamental steps in how galaxies form and evolve. Mergers occur when two (or more) galaxies collide. This interaction can radically...

Water flowing on Mars

NASA has announced that the Mars Reconnaissance Orbiter snapped some interesting photos that seem to indicate that water still flows on the surface of the red planet during the summer months. No water was directly detected...

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...

The Big Bang is not going anywhere.

On the 4th of February a paper was published detailing a Universe that didn’t need a Big Bang. While it is very interesting (you can read it here) I find myself once again at odds with how theoretical papers are formulated. The paper details a mathematical robust way to solve many cosmological conundrums. The flatness problem (discussed in this vlog), the value of dark energy and the nature of dark matter.

The taming of the screw

I have a mathematician friend who believes that anything that it is mathematically possible exists somewhere in the multiverse. She believes that there are some features that are so beautiful, that it would be a crime if they were simply quirks of the Universal language.

NASA’s discovery of water on Mars Billions of years ago, Mars looked more welcoming to life than Earth was at the time. We have seen evidence of ancient lakes and river beds, but nowadays water...

Supermassive Black Hole in RX J1532: the Destroyer of Worlds

From the NASA website: Astronomers have used NASA's Chandra X-ray Observatory and a suite of other telescopes to reveal one of the most powerful black holes known. The black hole has created enormous structures in...

The first concrete evidence of Cosmic Inflation?

It was announced on Monday that the Background Imaging of Cosmic Extragalactic Polarisation 2 (BICEP2 - don't you love projects acronyms?) experiment at the South Pole found a special pattern in the cosmic microwave background...

Why the discovery of gravitational waves is so important

Today, in my day job I wrote about the momentous discovery of gravitational waves by LIGO. There are four major discoveries associated with the detection: First of all, today it was announced that on 14th September...
