Scientists Detect Newborn Planet That Could Be Forming Moon
For the first time, scientists have discovered what appears to be a brand new planet, 395 light-years from Earth, that could be forming moons.
Scientists using the Atacama Large Millimeter/submillimeter Array, or ALMA, recently detected gas in a circumplanetary disk, the third one ever discovered.
The researchers say, suggests the presence of a very young, Jupiter-sized exoplanet, according to the National Radio Astronomy Observatory and research published in The Astrophysical Journal Letters.
The discovery of the disk, and possible newborn planet, was made as scientists studied the young star, AS 209, in the constellation Ophiuchus.
In the core of a big empty space in the gas around the star, they saw a blob of emitted light. Due to host star's age of only 1.6M yrs, experts claim the exoplanet may be the youngest ever discovered.
They also hope to confirm the planet’s presence with future observations using the James Webb Space Telescope.
As per astronomy professor Jaehan Bae, the best way to study planet formation is to see planets as they form. Thanks to strong telescopes like ALMA and JWST, we are living in an era where it occurs.
