A White Dwarf is Starting to Crystallize into Diamond

https://www.universetoday.com/161929/a- … o-diamond/

White dwarfs are the stellar remnants of stars like our Sun. They’re strange objects, and astrophysicists think their cores can crystallize into enormous diamonds. But they need to find more of these strange objects, and they need to know their ages, to understand how and when it happens.

Nancy Grace Roman Could Detect Supermassive Dark Stars

https://www.universetoday.com/162063/na … ark-stars/

The first stars of the universe were very different than the stars we see today. They were made purely of hydrogen and helium, without heavier elements to help them generate energy in their core. As a result, they were likely hundreds of times more massive than the Sun. But some of the first stars may have been even stranger. In the early universe, dark matter could have been more concentrated than it is now, and it may have powered strange stellar objects known as dark stars.

Imagine being on a planet, orbiting a star that had been ejected into intergalactic space.  The sky at night would be completely black, with tens of thousands of light years to the nearest star.  Interstellar travel would be out of the question.  It would be a bit depressing.  On the other side of things, there is zero possibility of space invaders turning up and invading your planet.


"Plan and prepare for every possibility, and you will never act. It is nobler to have courage as we stumble into half the things we fear than to analyse every possible obstacle and begin nothing. Great things are achieved by embracing great dangers."

Similar to the gravastar object hypothesized, on the horizon there is a thin shell of matter a portmanteau of the words "gravitational vacuum star"
