Astronomers spot Earth sized white dwarf made of Diamonds!!!

It can dwarf even the most bling of rings on Earth.
Researchers have discovered a star the size of our planet made entirely from diamond. The coldest, faintest white dwarf star ever detected, it is so cool that its carbon has crystallized, forming the Earth-size diamond in space.

‘It’s a really remarkable object,’ said David Kaplan, a professor at the University of Wisconsin-Milwaukee.
‘These things should be out there, but because they are so dim they are very hard to find.’

Kaplan and his colleagues found this stellar gem using the National Radio Astronomy Observatory’s (NRAO) Green Bank Telescope (GBT) and Very Long Baseline Array (VLBA), as well as other observatories.

White dwarfs are the extremely dense end-states of stars like our Sun that have collapsed to form an object approximately the size of the Earth.

Composed mostly of carbon and oxygen, white dwarfs slowly cool and fade over billions of years.

The object in this new study is likely the same age as the Milky Way, approximately 11 billion years old.
Pulsars are rapidly spinning neutron stars, the superdense remains of massive stars that have exploded as supernovas.

As neutron stars spin, lighthouse-like beams of radio waves, streaming from the poles of its powerful magnetic field, sweep through space.
