Jupiter is known as a king of the planetary house. It has the capacity to hold about 2.5 times as much mass as all the remaining planets hold in combined with a huge gravitational force. According to the findings published in the journal PNAS, researchers have found meteorites could reveal the fact that Jupiter is as old as our solar system is. It also explained the process of Earth’s development as well. Lead author Thomas S. Kruijer of the Lawrence Livermore National Laboratory had a trip to find out the age of Jupiter.
One of the cosmochemist along with his colleagues while studying at the University of Muenster noticed the two different patterns of meteorites. One of the patterns had a distinct isotopic signature while the other atoms such as iron, tungsten, molybdenum and even heavier elements weighed down by extra neutrons. Those isotopes originated while supernova explosion and marked the death of a particular star. Those elements went to fill other stars that could fold into planets and asteroids, including the chunks that fell to Earth as meteorites.
Kruijer said, “The only mechanism or way to do this is to have a gas giant in between them.” “Because only such a body is large enough to separate such large reservoirs”, he further added. Debris from different stellar explosions merged together to form a homogeneous mixture. It looked as if both the groups were separated long back and were not allowed to combine with each other.
According to the scientist, Jupiter’s massive body behaved like a blockade, keeping the new supernova material away from interacting with the well-mixed debris further. After studying the isotopes of tungsten and molybdenum, they worked to know the real mystery behind the separation of the two populations soon after the emergence of the solar system around 4.6 million years ago. Kruijer concluded saying, “In a way, we should be thankful to Jupiter that acted as a far less inviting home for life to emerge.”
