Distant Galaxy And Colliding Exoplanets


Distant Galaxy And Colliding Exoplanets

Astronomers are quite sure that the earth will cool down in 4.2 billion years and will collide in distant galaxy with a Mars-like cosmic rock and will reduce to a massive ball of lava. And they also expect that this will eventually become the moon of the earth, which means a beautiful ending of the debris of the collision.

Exoplanets Collide In The Distant Galaxy

The astronomers explain that this kind of cosmic body collision is common in the young solar system, but becomes a rare incident as time rolls on. The giant planets find their particular path, and the stars either absorb or blow the debris away. But NASA scientists inform that the solar system is witnessing an exception of this format in a distant galaxy.

There is a binary solar system at a distance of approximately 300 light-years from our earth, namely BD+ 20 307, where two Earth-like exoplanets have crashed. It results in a hot cloud of debris and dust, and this is visible in the infrared telescopes. The solar system, which is more than 1 billion years old, is not accustomed to the smash like this one. So, astronomers think that solar systems are also like humans. They struggle among themselves to elevate.

A scientist of Carnegie Institute of Science Alycia Weinberger said this is a rare incident happened in the cosmic world history.

Dust Clouds In The Distant Galaxy

Clouds of dust are floating everywhere in space. When this dust gets accumulated floating around the stars, they stick to each other firmly and form large, dense planets. This planet formation takes millions of years. They grow to a massive object and revolve around the sun in a particular path due to gravitational force. The smaller particles or debris formed during a cosmic collision or dust accumulation either pulled towards the star or blown away in the solar wind to the ring at the outer edges.

Our solar system is expanded to millions of miles beyond the Neptune’s orbit, and a number of rocky objects gathered there. The ring-shaped outer edge is known as the Kuiper belt. These objects include Pluto, the furthest planet from the sun. All the objects in this area are very cold because of their distance from the sun.

What The Astronomers Say

The astronomers first got the trace of a planetary collision ten years back in the star system BD +20 307 10. The feature which was striking about the outer edge was that the temperature at that far distant cloud dust is warmer than it should be. It was about ten times hotter than expected. Then they agreed upon the fact that there must be some cosmic collision that occurred recently, which has raised the temperature significantly.

Weinberger and his teammates became sure about it after observing a satellite, SOFIA. They observed that the density of the cloud is increased significantly compared to that of 10 years back. It indicates there is a remarkable increase in temperature.
