Astronomers have made a groundbreaking discovery in the #protoplanetary disc of V883 Orionis, detecting complex #organic molecules such as ethylene glycol and glycolonitrile. These compounds are potential precursors to sugars and #AminoAcids, suggesting that the building blocks of #life may form widely throughout the Universe. 🌌 #Astrophysics #OrganicMolecules

For decades, scientists have debated how small #exoplanets form.
New model suggests that #planets form in narrow rings at specific locations in the #protoplanetary disk, making #planet formation more organized than previously believed.
Simulations also imply that up to about 1% of super-Earth and mini-Neptune systems could host Earth-like planets within the #habitable zone.
This implies an occurrence rate of approximately one Earth-like planet per 300 sun-like stars.

Solving the mystery of how #planets like Earth form is an important question for understanding the origin of life.
Planets are thought to form when interstellar dust and gas collect in a #protoplanetary disk surrounding a #protostar, but it has been unclear how #planet formation begins.
By observing protoplanetary disks without dark rings, astronomers can study systems where giant planets have not yet formed.
