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...

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...

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...

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...

Interstellar Travel Meets The Real Universe

Interstellar travel is about to go from a Sci-fi idea to physical reality, but the jump comes with a series of considerations that fiction writers don't have to consider. This could work as an introduction...

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).

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...

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.

Negative mass could theoretically exists in our Universe

Saoussen Mbarek and Manu Paranjape at the Université de Montréal in Canada have published a paper that details the conditions for negative mass to exist in our Universe without the need to include exotic...

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...
