Hubble Telescope Captures Giant Collision in an Exoplanetary System.

According to ТСН: At the beginning of our Solar System's existence, a chaotic process occurred, similar to a "bumper car" track, where planetesimals, asteroids, and comets constantly collided. Now astronomers have been able to observe similar processes in the planetary system of one of the neighboring stars.

The Hubble Telescope captured unique images of catastrophic collisions in the planetary system around the star Fomalhaut, which is located just 25 light-years from Earth.

"Appeared Out of Nowhere"

Paul Kalas, the lead researcher from the University of California, Berkeley, does not hide his excitement about this discovery.

"This is definitely the first time I have seen a light source appear out of nowhere in an exoplanetary system. It was not present in any of our previous Hubble images. This means we have just witnessed the violent collision of two massive objects and the formation of a huge debris cloud, unlike anything in our Solar System today," said the scientist.

The Mystery of the Missing Planet

This discovery has been pivotal in an ancient scientific debate. In 2008, scientists announced the discovery of the planet Fomalhaut b, which became the first exoplanet found using visible light. However, new data suggests that the planet never actually existed. The object observed previously turned out to be a cloud of dust formed from the collision of planetesimals, and this cloud subsequently disappeared.

Furthermore, Hubble recently captured a second point of light (named cs2) near the site of the first "accident."

Theories Are Breaking Apart

Astronomers are astonished by the frequency of these events. It was previously thought that such large collisions occurred once every 100,000 years, but Hubble has recorded two instances in just 20 years of observations.

"If you had a movie of the last 3000 years and sped it up so that each year was a fraction of a second, you would see the Fomalhaut planetary system sparkling from these collisions," Kalas explained.

According to scientists' rough estimates, the colliding objects had a diameter of about 60 kilometers. Overall, the Fomalhaut system likely contains around 300 million such bodies.

A Lesson for the Future

This discovery serves as an important warning for exoplanet researchers. Dust clouds can "mask" themselves as planets by reflecting the light of a star.

"This is a cautionary tale for future missions attempting to detect exoplanets in reflected light," emphasize NASA.

The next observations of the system will be even more thorough. In addition to Hubble, the James Webb Telescope will also be involved. Its infrared camera (NIRCam) will be able to determine the composition of the dust cloud and even check if it contains water ice.

It is worth noting that the Webb telescope has already discovered a planet with a carbon atmosphere shaped like a lemon, which challenges theories of world formation.

Studying the Fomalhaut planetary system opens new horizons in our understanding of planet formation and their evolutionary development. The collected data not only calls previous theories into question but also emphasizes the importance of improving observation technologies to detect similar phenomena in other systems.
