Was there ever life on
Mars? Scientists have been receiving many hints from time
to time on this question. Now scientists have got another indication related to
life on this red planet. They have found carbonate compounds containing
nitrogen of Mars.
Japan team made this
discovery
Japan's team found such
organic matter in a Mars meteorite that contains nitrogen. The team includes
Atsuko Kobayashi, a scientist at the Tokyo Institute of Technology's Earth-Life
Science Institute, and Mizuho Koike, a scientist at the Institute of Space and
Astronautical Sciences of the Japanese Aerospace Corporation.
4 billion years old, this substance is about 4 billion years old. These substances were frozen in water inside the ground, which shows that there would be a glut of organic matter and water on Mars at that time. This shows that the possibilities of life on Mars at that time have further strengthened.
Answers to these
questions were being searched long ago
For decades, scientists
have been trying to know whether there are organic substances on Mars and if
so, where did they come from. Studies going on from Mars rover have also found
strong evidence of organic matter there, but little information has been found
about where they came from, how old they are and how far they have spread and
their biochemistry activities Is related to
How did you get this meteorite?
The meteorites of Mars
are those pieces of its surface that reached space with the explosion after
hitting the meteor from Mars and then later came to Earth. They get special
information about the history of Mars. One of these meteorites fell in
Antarctica has been named Allen Hills (ALH) 84001. This meteorite was found by
scientists in the year 1984.
What did you get in
this meteorite?
It contained
orange-colored carbonate minerals that were frozen in salt water on Mars 4
billion years ago. These minerals provide evidence of water on Mars 4 billion
years ago. A lot of research was done on whether there was life on Mars at that
time.
Adulterated substances
of the Earth made it difficult
Not much was known
before Antarctica was adulterated in this meteorite, but now developed
technology has shown that the nitrogen found in this meteorite was actually
Mars. The carbonate minerals of ALH84001 were studied with special analysis
techniques. Now the team is confident that they have obtained convincing
evidence of 4 billion years old nitrogenous organic matter on Mars.
New technology helped
Adulteration of
substances of our planet is a serious problem while studying the substances of
external planets. To avoid this adulteration, the team developed a new
technique for developing samples. He used silver tape over the sample in his
lab to remove fine carbonate particles. After this, he inserted an ion beam
with the help of electron microscope and pulled out the adulterated particles.
He then detected the presence of nitrogen with micro XANES technology. They
found that the carbonate minerals were from Mars itself.
What were the blue
planet then this red planet of today?
Researchers found that it is clear that organic nitrogen was present on Mars. Then there was less oxidized water, and plenty of organic matter. Researchers say that today's red planet was probably blue then.
