its showing some UNUSUAL properties..

2015 has been quite a year for astronomy.  And now scientists have detected a red pulsar so bright it is actually detectable in a galaxy 53 million light years away.  This was previously unconsidered to have any effect on the general brightness scale of a galaxy.  But this one is so strong that it is actually affecting things in the galaxy Messier 87.

Later in life, stars like our Sun undergo significant changes. They become very bright and swell up to huge size, swallowing any planets within a radius equivalent to Earth’s distance from the Sun.

Near the end of their lifetime, these stars begin to pulsate, increasing and decreasing their brightness every few hundred days.

Let’s find out more on how they detected this phenomenon on page 2
