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.

Rulers of the Oort Cloud

A new dwarf planet has recently been discovered in the solar system, orbiting at about 10 light hours from our Star. This is the furthest object belonging to our planetary system that we have been...

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...

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 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).

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...

Forensic Astronomers: ART DIVISION.

I firmly believe that the popularity of Astronomy is strongly related to our ability of producing awe-inducing photographs of the furthest corner of the cosmos. While looking up interesting pictures to talk about on the...

Alfredo’s Top 5 Physics & Astrophysics Stories Of 2015

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...

We have discovered a brown dwarf colder than ice

Associate Professor Kevin Luhman of Penn State University has discovered the coldest brown dwarf yet using the NASA's Wide-field Infrared Survey Explorer. A brown dwarf is a massive gaseous object which is on the low...
