These particles may act as organic building blocks for even more complicated molecules and their discovery was completely unexpected because of the chemical composition of the atmosphere (which lacks oxygen and mainly consists of nitrogen and methane).]]></description></item><item><title><![CDATA[Origin of &quot;Breathable&quot; Atmosphere on Earth Found]]></title><link>http://www.plime.com/science/l/39852/1/</link><description><![CDATA[Geologists have uncovered evidence of when Earth may have first supported an oxygen-rich atmosphere similar to the one we breathe today. The study suggests that upheavals in the earth&#8217;s crust initiated a kind of reverse-greenhouse effect 500 million years ago that cooled the world&#8217;s oceans, spawned giant plankton blooms, and sent a burst of oxygen into the atmosphere.]]></description></item><item><title><![CDATA[See Saturn Now: Lord of the Rings Rocks]]></title><link>http://www.plime.com/astronomy/l/51684/1/</link><description><![CDATA[Saturn is now at its best in our late-winter sky. It appears below and to the left of the conspicuous &quot;sickle&quot; or backwards question-mark pattern of stars marking the head and mane of the constellation of Leo, the Lion.<br/><br/>What we see with the naked eye is a bright yellowish-white &quot;star&quot; shining with a steady light.]]></description></item><item><title><![CDATA[Setting stars reveal planetary secrets]]></title><link>http://www.plime.com/astronomy/l/40725/1/</link><description><![CDATA[Watching the stars set from the surface of the Earth may be a romantic pastime but when a spacecraft does it from orbit, it can reveal hidden details about a planet&#8217;s atmosphere. 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></item><item><title><![CDATA[Planetary scientists close in on Saturn&#8217;s elusive rotation]]></title><link>http://www.plime.com/astronomy/l/44033/1/</link><description><![CDATA[Somewhere deep below Saturn&#8217;s cloud tops, the planet rotates at a constant speed. Determining this interior period of rotation has proven extremely complicated.

The New Horizons spacecraft recently documented the moon's glowing aurora, however, giving researchers a chance to solve the atmospheric mystery.]]></description></item><item><title><![CDATA[New 60th Moon of Saturn Discovered]]></title><link>http://www.plime.com/astronomy/l/28115/1/</link><description><![CDATA[The scientists behind the Cassini orbiter have announced the discovery of Saturn's 60th moon, a little thing that showed up in time-lapse photography of the ringed planet.]]></description></item><item><title><![CDATA[Seeds of life found near Saturn]]></title><link>http://www.plime.com/astronomy/l/55876/1/</link><description><![CDATA[A sniff test of water vapor spewing from Saturn's moon Enceladus shows it is gushing with organic molecules, increasing the possibility of life existing somewhere in the Saturn system.]]></description></item><item><title><![CDATA[The Vanishing Rings of Saturn]]></title><link>http://www.plime.com/astronomy/l/54959/1/</link><description><![CDATA[Saturn: jewel of the solar system, taker of breaths, ringed beauty.

That was close to the rough rotation rate scientists have obtained by tracking the motion of Saturn's clouds, suggesting the pulse period is tied to the planet's rotation rate. !!Sound and Video links!!]]></description></item><item><title><![CDATA[Animals across Europe falling asleep due to heat wave]]></title><link>http://www.plime.com/animals/l/28170/1/</link><description><![CDATA[With some parts of Europe currently in the middle of a heat wave, it seems it's not only people who suffer from the soaring temperatures.]]></description></item><item><title><![CDATA[First unchanging 'soliton' wave found in space]]></title><link>http://www.plime.com/astronomy/l/54785/1/</link><description><![CDATA[An unusual electrical disturbance has been spotted in space, travelling unchanged through the ionised gas surrounding Earth.
