The Destruction of a Death Star

The Kepler Spacecraft has found an authentic ‘Death Star’, and it isn’t the one that Darth Vader built, although it is as destructive.  This ‘Death Star’ is a dying star that is literally disintegrating nearby planets and any object that gets in its path.  One of the most interesting aspects of this find is that observing its behavior can help us understand how dead stars obliterate their planetary systems and gives us an idea of what may happen to Earth in a few billion years when our own sun begins to die.

Death Star

This ‘Death Star’, aka WD1145+017, was spotted previously by astronomers tearing apart a little planetary body they speculated might be a moon or dwarf planet.  WD1145+017 is a white dwarf that lies about 570 light-years from Earth.  White dwarfs are very dense, and its important to note that most stars will eventually transform into a white dwarf  at some point in their life.

Boris Gansicke, an astronomer at the University of Warwick England who also authored the study, said,  “Our sun will one day balloon out to become a red giant star, wiping out Mercury and Venus and maybe Earth, before it becomes a white dwarf.  By looking at this white dwarf, we get a look at what the future of the solar system might be like.  It’s exciting and unexpected that we can see this kind of dramatic change on human timescales.  We can see how things evolve over time.  How does the integration of a planetisimal work?  How long does the whole thing last?  Will we be able to see everything disappear in a year or two?  How does the disk of dust around the star evolve?  How will the metal content of the white dwarf change?”  So many unanswered questions, but with any luck, Boris may soon have some answers to share with us all.

    It is rare to get an experienced person in whom you may have some trust. In the world of today, nobody absolutely cares about showing others the solution in this subject matter. How blessed I am to have actually found a really wonderful blog as this. It is really people like you exactly who make a true difference these days through the suggestions they reveal.

    Pas sur ^^, effectivement, HTC est dead tant que l’actuel PDg reste en fonction. En tout cas nous n’avons aucun détail de cet arrangement. Un peu dommage vue l’étalage des procès mis en avant. N’empêche que j’en avait moi aussi ras le bol des procès à 2 balles. Un accord est trou ? C’est génial.

    Tagesspiegel? Oder meinst Du den hier zitier­ten aus der Zeit?Dass es letzt­lich um Machterhalt des isla­mi­schen Klerus geht ist schon klar. Ich werde dazu heute noch etwas zum Thema Iran ver­öf­fent­li­chen (Gastbeitrag). Da geht es um Ähn­li­ches: näm­lich, dass die ira­ni­schen Mullahs mit dem Verlust der Deutungshoheit auch die poli­ti­sche Macht ver­lie­ren. Das wird ähn­lich so sein in Pakistan und Afghanistan.
