Over 4000 exoplanets have been discovered so far, but what happens when they collide with each other?

A newly published study looks at a single star system BD + 20 307, is more than 300 light-years from Earth, which is the evidence of the two exo-planets have been recently struck.

Astronomers analyzed data from NASA’s Stratospheric Observatory for Infrared Astronomy, which “turned out to be the infrared luminosity of the debris has been increased by more than 10 [per cent] — as a sign that there is still more of a warm fabric,” according to a statement on the announcement of the results.

Dust and debris were first spotted by the ground observatories and the Spitzer Space Telescope, about a decade ago.

“The warm dust around BD +20 307 gives us a look at what is the most catastrophic effects among the rocky planets, it would have been,” said the study’s lead author, Maggie Thompson, in a statement. “We would like to know how this system will evolve following the extreme impact.”

“Because of the extreme dust and the small diameter of the disk of BD +20 307 has a short of the predicted collision time, and it is, therefore, an interesting target to look at changes in the quantity of the substance, and its composition is the period of time,” the study’s abstract states that “a catastrophic collision between planetary-scale bodies, is the most likely origin for the system in extreme dust.”

In the new study, published in The Astrophysical Journal.

“This is a rare opportunity to study a catastrophic collision will occur late in the planetary system, and the history of it,” said Alycia Weinberger, a scientist at the Carnegie Institution for Science’s Department of Terrestrial Magnetism, in a statement. “The SOFIA observations reveal the change in the dust disk on a timescale of a few years.”

Some scientists believe that the Earth and the Moon, can also be formed in a similar manner, after an asteroid the size of Mars hit the planet, about 4.5 billion years ago.

In a separate study, which was published in January, has also been speculated that this ancient collision with a Mars-sized object that is responsible for life on Earth.
