The Universe’s composition is the same everywhere

The Japanese X-ray satellite SUZAKU has looked at the distribution of gas around the Virgo cluster, a large galaxy cluster close to the Milky Way and the second brightest in X-rays. It discovered that...

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...

Gravitational Waves Were Used To Look Inside Neutron Stars

Last October, scientists witnessed the first neutron star collision thanks to gravitational wave observations and the subsequent use of regular telescopes. Those observations were the first step towards a new method of astronomy, and...

What’s The Best Name For A Moon’s Moon?

The latest episode of The Astroholic LIVE was able to accidentally capture (or presciently if you want to give me more credit) the zeitgeist of this week’s discussion about moons. We talked about the...

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...

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...

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...

The Alpha and The Omega (Centauri) of Habitable Planets

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,...

Visiting The European Astronaut Centre

Recently, I've had the chance to visit the European Astronaut Centre, one of the important facilities belonging to the European Space Agency.  I was there as part of a research test and I got the...

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.
