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.

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...

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...

The first measurement of an exoplanet day.

Dutch Astronomers using ESO's Very Large Telescope were able to measure the rotational speed of a planet outside the Solar System for the first time. Ignas Snellen and his colleagues at Leiden University in the...

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...

Probing the furthest Universe to understand how spiral galaxies formed.

A new paper accepted for publication this month has highlighted how spiral galaxies came to form in the early Universe. By using the power of the Atacama Large Millimeter/submillimeter Array (ALMA), a team lead by...

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...

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...

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.

Observation of Dirac Monopoles in a Synthetic Magnetic Field

What are magnetic monopoles and why are they important? If you ever broke a magnet in two when you were little (I was a weird kid, leave me be) you might have noticed that you...
