It works by watching stars from space, while they drop behind the atmosphere of a planet under investigation, before disappearing from view below the planet&#8217;s horizon.]]></description><link>http://www.plime.com/plime-com/l/40725/1/</link><guid>http://www.plime.com/plime-com/l/40725/1/</guid><category>plime.com</category><pubDate></pubDate> </item><item><title><![CDATA[Bonn astronomers simulate life and death in the universe]]></title><description><![CDATA[Stars always evolve in the universe in large groups, known as clusters. Astronomers distinguish these formations by their age and size. The question of how star clusters are created from interstellar gas clouds and why they then develop in different ways has now been answered by researchers at the Argelander Institute for Astronomy at the University of Bonn with the aid of computer simulations.]]></description><link>http://www.plime.com/plime-com/l/39987/1/</link><guid>http://www.plime.com/plime-com/l/39987/1/</guid><category>plime.com</category><pubDate></pubDate> </item><item><title><![CDATA[Galaxies give birth to stars on cosmic highways]]></title><description><![CDATA[Galaxies tend to give birth to their stars on the road, while travelling down intergalactic highways towards cosmic cities called galaxy clusters, new Spitzer Space Telescope observations reveal.

Planets and much on them, including humans, come from dust &#8212; mostly from dying stars. But where did the dust that helped form those early stars come from? A NASA telescope may have spotted one of the answers. It's in the wind bursting out of super-massive black holes.]]></description><link>http://www.plime.com/plime-com/l/37916/1/</link><guid>http://www.plime.com/plime-com/l/37916/1/</guid><category>plime.com</category><pubDate></pubDate> </item><item><title><![CDATA[Astronomers finding 2 new planets a month]]></title><description><![CDATA[As of July 20, the latest available date, 246 extrasolar planets had been detected circling other stars in the Milky Way galaxy.
