Scientists are excited about a major breakthrough that have been made for the first time, Joinfo.com informs with the reference to The Daily Mail. The astronomers from Australia and the US got a proof of a long-held theory about the planets outside our Solar System . They have captured how an alien world forming around a newborn star.
The birth of the planet as it forms from the cosmic clouds of gas and dust particles that surround it has been directly observed for the first time.
Researchers in Arizona have been studying LkCa 15, a young star surrounded by a ring of debris, because they believed it may be accumulating into a planet. See the illustration:
By observing light at various wavelengths, the astronomers have now been proved correct and said LkCa 15 could provide more chances to directly witness similar processes in other regions.
While the process of planet formation and growth by gradual gas and dust accumulation is well-known, it has never been witnessed first-hand until now.
None of the previously discovered planets outside of our solar system are still in their formation stage, which means LkCa 15 offers a unique chance to study this development.
Astronomers regard transition disks – vast rings of gas and dust orbiting around newborn stars – as colossal laboratories for the study of planet formation.
These disks typically present inner clear areas with no visible dust or gas.
This is a phenomenon that has been attributed to fledgling planets sweeping material away as they travel around the star.
Transition disks have previously been found that show evidence of the presence of young planets.
As reported earlier this week, scientists have found a Venus-sized planet orbiting a star only 39 light-years from Earth. According to the last information, the planet is within easy telescope views and it circles too close to a parent star, a red dwarf known as Gliese 1132.
