A Forty Year Old Mystery Is Solved

Posted by on Wednesday, June 7, 2017, In : Astronomy 
After forty years of speculations ranging from exotic particle decays to advanced alien civilizations, the famous 6EQUJ5 signal has now been explained, and the explanation is embarrassingly rather basic.

In August 1977, astronomers at the Big Ear observatory at Ohio State university were scanning the sky for radio signals from space. There are numerous sources of radio waves in the galaxy, and a lot of interesting science can be done using a map of the sources of radio signals. And of course m...

X-Ray Navigation & Communication

Yesterday I wrote about the theory of neutron stars and pulsars, and about the NICER mission that is about to begin examining them in more detail. After fifty years of theoretical study and limited astronomical data, we are soon to have a dedicated x-ray telescope with the primary purpose of studying the composition and properties of pulsars in the galaxy.

However the mission has a second goal, and one with a more practical purpose than studying distant neutron stars and pulsars. The mission w...

A NICER Mission

Posted by on Thursday, June 1, 2017, In : Astronomy 
Nearly fifty years ago, astronomers discovered a bizarre signal in the sky coming from an unknown, mysterious object. Where most astrophysical objects send a steady stream of particles, light and radio waves, this new object was rapidly pulsing x-rays. 

These objects were eventually found to be very compact objects, known as neutron stars. When a star reaches the end of its life, and has exhausted its supply of nuclear fuel, it will expel its outer layers and the core will collapse into a smal...
