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.
The mysterious world with two “ghosts” captured by Hubble

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.

Mwaka 2017, kwa kutumia data kutoka kwa darubini ya Hubble, wataalamu wa nyota waligundua kivuli cha ajabu kilichokuwa kikipanda juu ya diski kubwa ya vumbi na gesi iliyozunguka nyota ndogo ya TW Hydra. <unk>Spectrum<unk> haikutoka kwenye sayari, bali kutoka kwenye diski nyingine ya gesi na vumbi, ndogo sana na yenye pembe kidogo kuliko gari la nje. Hivi karibuni, roho ya pili inaendelea kuonekana. Dunia ya ajabu na roho mbili iliyokamatwa na Hubble Dunia ya ajabu na roho mbili ilikamatwa na Hubble (Picha: NASA/AURA/STSc). Kulingana na SciTech Daily, inatambuliwa kuwa diski ya pili ya vumbi. <unk>Hizi mbili <unk>roho<unk> kutoa mtazamo breathtaking ya sayari mbili katika hatua ya unprecedented, viinitete viwili ya umbo haijulikani. Timu inayoongozwa na mtaalamu wa nyota John Cebes kutoka Taasisi ya Sayansi ya Teleskopi ya Anga huko Maryland, Marekani, na Shirika la Anga la Ulaya (ESA) ilisema kuwa pia ni diski mbili za protoplanetary tofauti kabisa na zile zinazojulikana. Mimi tu kuona moja kwa mara ya kwanza kwa sababu wao ni sawa, au angalau karibu na kila mmoja na kazi kwa njia ileile. Kwa ghafla, roho hizi mbili zinatenganishwa na kuanza kuonyesha kuwa ni diski mbili tofauti, zinajiendesha tofauti, ndege za mzunguko pia ni tofauti kidogo. Hii bado ni ya kutatanisha na ya kuvutia kwa wanasayansi, kwani itafunua mambo ambayo hayajulikani hapo awali kuhusu jinsi sayari ilivyotokea. "Takwimu za awali zinaonyesha kwamba sayari hizo ndogo ziko katika eneo la umbali wa ""Jupiter"" kutoka kwa Jua, zikizunguka nyota yao kila baada ya miaka 15, na ndege ya mzunguko imepinda kwa digrii 5-7 kuelekea Jua." na diski ya protoplanetary ya nyota mzazi. Kushangaza, inafaa kikamilifu "Solar System Style Architecture", inaweza kutoa wataalamu wa nyota na mtazamo "kupitia hewa" juu ya zamani, kuelewa jinsi dunia yetu alizaliwa. Diski ya protoplanetary ya nyota ya mzazi pia ina diski mbili za ndani na za nje, ambazo diski ya nje inaweza kuwa na nusu ya mara kadhaa kubwa kuliko ile ya ukanda wa Kuiper wa mfumo wa jua. Pia, kuna pengo lisilo la kawaida lililo umbali maradufu wa umbali kati ya Pluto na Jua, jambo linalodokeza kwamba kuna sayari ya tatu. Utafiti huo umepatikana katika jarida la The Journal of Astrophysics. "Kama kuna kosa katika makala ""NASA ilitangaza kugunduliwa asiyeonekana kwa kitu chenye roho mbili,"" au ikiwa maudhui ni sahihi, tafadhali wasiliana nasi ili tuweze kurekebisha." Mwaka 2017, kwa kutumia data kutoka kwa darubini ya Hubble, wataalamu wa nyota waligundua kivuli cha ajabu kikiwa kimeenea juu ya uso wa diski ya vumbi na gesi yenye umbo la pancake.
