Hubble Watches Exoplanet 70b PDS grows when collecting gas and dust

The Hubble Space Telescope is watching exoplanet called PDS 70b because it collects mass in a distant star system. NASA said that exoplanet collected gas and dust slowly because the world built masses during millions of years. The researchers have been able to use Hubble to directly measure the mass growth rate of PDS 70b for the first time using the ultraviolet sensitivity of space telescope to capture radiation created by very hot gases falling to the planet.

Exoplanet is a large-scale world that orbits his star with a distance that is roughly the same as Uranus orbits the sun. The 70B PDS moved through the mass of gas and dust when orbiting his star, and astronomers said the planet began to form around 5 million years ago. They believe it might approach the end of the formation process.

Observing the planet gives astronomers new ways to study the planetary formation. They believe this planet can help other astronomers learn about how gas giants are formed in remote solar systems. At present, scientists don’t know much about how the gas giant planet shape. The planet’s system provides an opportunity to witness the material that falls into a planet and opens a new area for research on the type of planet.

The 70B PDS is also one of the few exoplanets which are directly assigned by the telescope. More than 4000 exoplanets that have been cataloged, only 15 are directly associated until now by the telescope. Scientists note that exoplanets are very far and small they are usually only dots, even in the best photos taken.

The team uses new techniques through Hubble to directly multiply the PDS 70B, opening a new route for future exoplanet research. 70B PDS orbiting orange dwarf star named PDS 70, it is known to have two planets that are actively formed in massive discs of dust and gas around the star. This system is around 370 light years from Earth at Constellation Centaurus.
