Scientists find evidence of 'baby' planet in making

Scientists find evidence of baby planet in making.

Everyday scientists and astronomers keep researching on new developments in the space. After researching and studying, scientists have found evidence that there is a baby planet in making.

According to Feng Long, it is very challenging to directly detect young planets because planets are always too faint for us to see and are embedded with gas and dust. For researching and studying Long decided to re-examine the plotoplanetary disk LkCa 15. It is located 518 light years away in the direction of taurus constellation.

While examining Long discovered that there were two separate and bright bunches orbiting within the disk. These bunches were in the shape of small clump and a larger arc. She said that this degree of separation doesn't happens. So, it is mathematically important.

Lagrange points are the long points to position in space, where two bodies in motion  produce enhanced regions of attraction around them where matter may accumulate. As per research, the arc and clump detected are located at L4 and L5 points. At about 60 degrees there is a hidden planet which is causing accumulation of dust  at L4 and L5 points.

As per results the planet is approximately equal to the size of Neptune or Saturn and it is around one to three million years old.

Directly imaging the small and newborn planet is not possible due to technology constraints, but Long believes  that further ALMA observations of LkCa 15 can provide additional evidence for supporting her discovery.
