Astronomers Spot a Real-Life “Death Star” Wrecking a Planet

This is a continuation of this incredible space finding.  And no surprise the hubble space telescope is responsible:

Recently, astronomers detected a dead star tearing apart a planetesimal — a small planetary body, such as a dwarf planet, large asteroid or moon. The dead star is a white dwarfknown as WD 1145+017, which lies about 570 light-years from Earth in the constellation Virgo

Scientists previously estimated that the amount of material seen circling the white dwarf was about equal to that contained by the 590-mile-wide (950 km) dwarf planet Ceres, the largest object in the main asteroid belt between Mars and Jupiter. They suggested that the white dwarf was ripping apart the planetary bodyafter it had spiraled too close to the dead star, and that the rock would be fully destroyed within about a million years.

Now Gänsicke and his colleagues find that this white dwarf system has rapidly evolved just months since its discovery.

“It’s exciting and unexpected that we can see this kind of dramatic change on human timescales,” Gänsicke told Space.com.

The fact that they can witness this thing on such a timescale makes it all the more rare.  As you know when we think of space we often think of timeframes in the 100s of millions or billions of years.

    In about 5,000,000,000 years. Of course the inner planets will have been long engulfed and devoured at least 4,000,000,000 years prior to this happening.
