A billion-ton pounding: evidence of an asteroid encountering a pulsar.

 A pulsar is a highly magnetised fastly rotating neutron star which formed during a supernova explosion. The name pulsar is a portmanteau for pulsating star, because it emits a beam of electromagnetic radiation usually...

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...

Kepler proves that planets are as old as galaxies. So where is everybody?

The oldest exoplanetary star-system has been discovered by Kepler. The system orbiting Kepler 444 was older than the Earth today when the Sun first shone light.

Lord of the Rings distance pinpointed

As I mentioned in a previous post, there are a few ways to measure the distance of a star in our galaxy. Unfortunately when the Luminosity is unknown and it is too far away to use parallaxes method, we are stumped for ways to estimate the distance. Once in a while though we get lucky and we have events that allow us to calculate distance in other ways. Circinus X-1 is one of these events. Circinus X-1 is an x-ray binary; an x-ray binary is a system of two stars where material from one companion is accreting on the neutron star, which in turns emits x-rays.

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.

Some Earths Like It Hot

Planetary systems form from the same cloud as its parent star. As the cloud contracts under the effect of gravity, the gas acquires more angular velocity. Spinning faster it flattens out into a disk...

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.

Testing Relativity With Nothing

There are two big problems with astrophysics, and they are called dark energy and dark matter. Dark energy is responsible for the accelerated expansion of the Universe. Dark matter keeps the galaxies together, and we...

Cracking the Moon

The Oceanus Procellarum (Ocean of Storms) is the largest of the lunar maria (seas) covering roughly 4 million square kilometers (about the surface area of the EU). Its wide flat basaltic surface was believed...

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...
