In 2017, using data from the Hubble telescope, astronomers detected a strange shadow sweeping across the surface of a giant pancake-shaped disc of dust and gas surrounding the red dwarf star TW Hydrae.
“Spectrum” it does not come from a planet, but from another disk of gas and dust, much smaller and slightly angled than the external drive. Recently, The second ghost keeps appearing.

According to SciTech Daily, it is identified as second dust disc. ϹThese two “ghosts” offer a breathtaking view of two planets at an unprecedented stage, two embryos of unknown shape.
The team led by astronomer John Cebes from the Space Telescope Science Institute in Maryland – USA and the European Space Agency (ƐSA) said that it is also two protoplanetary discs completely different from those known.
I only see one at first because they are identical, or at least close to each other and work the same way. Suddenly these two ghosts separate and begin to show that they are two separate discs, behave differently, the orbital planes are also slightly different.
This is still confusing and interesting for scientists, as it will reveal previously unknown things about how a planet came into being.
Preliminary data suggests that the young planets are located in a region roughly Jupiter’s distance from the Sun, orbiting their parent star every 15 years, with an orbital plane inclined 5-7 degrees to the Sun. with the parent star’s protoplanetary disk.
Surprise, it fits perfectly “Solar System Style Architecture”, can provide astronomers with a view “through the air” on the past, to understand how our world was born.
The parent star’s protoplanetary disk also consists of two inner and outer disks, the outer disk of which may have a radius several times greater than that of the Kuiper belt of the solar system. The disc also has a strange void at twice the distance between Pluto and the Sun, suggesting a third planet.
