 In
the solar system with many planets around the Sun, the Earth is the
only planet where creatures live. Scientists have sent the Hubble
Space Telescope to search for the possibility of other creatures on
other planets.
Scientists recently discovered water in stardust. That means life
may exist somewhere in the universe. This is the first time to actually
find H2O trapped inside stardust!
John Bradley at the Lawrence Livermore National Laboratory in California
looked into interplanetary dust particles found in the Earth’s stratosphere.
It was incredible that he could find tiny pockets of water. That means
the basic ingredient needed for life exists in space!
In the laboratory, he found how the water forms in space. The star
dust that contains oxygen is mostly made of silicates. It travels
through space and encounters the solar wind, the stream of charged
particles including high-energy hydrogen. When the two collide, hydrogen
and oxygen make water.
 Hope Ishii of
the University of Hawaii, who also participated in the research said,
“The implications are potentially huge.” The possibility for the origin
of life was confirmed.
The water is produced in space every day as the particles travel in
space. They may land on a planet and become the trigger of life. Intelligent
creatures may already live on some unknown planet. They may have built
a sophisticated civilization and want to find other creatures who
live on another planet just as we do.
Take a little interest in astronomy, and tell us what’s out there
in space. |
