  <description><![CDATA[Brown dwarfs are not quite stars and not quite planets. They are the missing links between the lowest mass stars and the highest mass planets possible. Scientists recently discovered the coolest brown dwarf known  --  an important discovery that may shed light on the development of planets beyond our solar system.]]></description>

  <description><![CDATA[A distant, dim flash in the sky marks the location of the biggest explosion ever recorded, as astronomers monitor a gamma ray burst brighter than 10 million galaxies combined. And astronomers have found tiny, early galaxies so thick with stars that they might never experience night as we do.]]></description>

  <description><![CDATA[NASA's Cassini spacecraft has found evidence of material orbiting Rhea, Saturn's second largest moon, which means Rhea could have rings. This is the first time rings have potentially been found around any moon. Astronomers speculate that a collision in the moon's distant past led to the rings' formation.]]></description>

  <description><![CDATA[The Cassini space probe was launched in 1997 and flew by Earth, Venus and Jupiter. It entered orbit around Saturn in 2004. One of Saturn's moons, Enceladus, is believed to have liquid water below its crusty surface. A daring flyby of Cassini into geyser plume of Enceladus has bolstered the idea.]]></description>

  <link>http://hubblesite.org/explore_astronomy/skywatch/#155</link>
  <description><![CDATA[Astronomers know that complex molecules are required building blocks for life, and can indicate that biological activity is present on distant worlds. Methane, which can come from volcanic eruptions, among other sources, is a key ingredient for the formation of life and also a by-product of microbial activity.]]></description>

  <link>http://hubblesite.org/explore_astronomy/skywatch/#154</link>
  <description><![CDATA[Saturn's moon, Titan, may have a deep, hidden ocean. The second largest moon in the solar system, Titan has long been thought to have an environment similar to that of early Earth, before life began putting oxygen into atmosphere.  If the ocean prediction is true, Titan will join three other solar system moons suspected of hiding underground oceans.]]></description>

  <description><![CDATA[For the first time, an organic molecule has been located in the atmosphere of a planet beyond our solar system. The planet itself can't sustain life, but could the molecule's presence is good news for life elsewhere.

Back on Earth, art and science merge as the Walter's Art Museum in Baltimore, Md., displays Hubble images on its walls. The special exhibit is the brainchild of a group of curating students at Johns Hopkins University, who worked with astrophysicists to create the display.]]></description>

  <link>http://hubblesite.org/explore_astronomy/skywatch/#152</link>
  <description><![CDATA[Mars was too salty to sustain life for much of its history, new evidence from the Opportunity rover on the Martian surface indicates. Minerals deposited in sedimentary rocks suggest they formed in extremely salty water  --  even saltier than oceans on Earth.  Such conditions would have made it inhospitable to even the toughest micro-organisms.]]></description>

  <description><![CDATA[Venus is much like planet Earth its composition, but also very different in other ways  --  it's bone-dry with little sign of water, experiences temperatures hot enough to melt lead, is enshrouded in a thick poisonous atmosphere of CO2 and sulfuric acid, and even rotates "backwards." 

Now we may have an explanation for this weirdness  --  a tremendous head-on collision of two bodies may have formed our planetary neighbor.]]></description>

  <link>http://hubblesite.org/explore_astronomy/skywatch/#150</link>
  <description><![CDATA[Gravitational lenses are like giant magnifying glasses in the sky. They occur where huge accumulations of matter, like galaxy clusters, create enough gravity to warp and magnify the light of objects beyond them. This enables us to see objects normally too far away to be viewed by even the most powerful telescopes.

Gravitational lenses were once thought to be rare. But astronomers using Hubble have found several, and new sky surveys found more. Scientists are now training a "digital robot" to find additional lenses.]]></description>

  <description><![CDATA[A mission to the Moon will search for water. Scientists would like to know if the Moon does have residual water, as hinted at by earlier missions.

The Lunar Crater Observation and Sensing Satellite will send an impactor into a dark crater at the Moon's south pole. Instruments will measure the plume produced by the impact to see what materials are present, looking particularly for water. LCROSS will launch in October 2008 and the impact will take place early in 2009.]]></description>

  <link>http://hubblesite.org/explore_astronomy/skywatch/#148</link>
  <description><![CDATA[Gravitational lensing is highly useful quirk of the universe. When vast amounts of matter accumulate  --  as in enormous clusters of galaxies  --  the intense gravity created distorts and magnifies the light of objects behind the cluster. The effect is like creating a giant magnifying glass in space. Astronomers recently used the effect to find one of the youngest galaxies ever seen, and track the placement of dark matter.]]></description>

  <description><![CDATA[Stars were recently found forming in a long tail of gas trailing away from a galaxy. We normally would not expect to see stars being born so far from their parent galaxy. Scientists believe the pressure of the galaxy's motion through space as it plummeted toward the center of a huge cluster of galaxies stripped away the gas that formed these "orphan stars."]]></description>
