About GG Tau A System:

It is a unique triple-star system which is located 489 light-years away from Earth.
The system is young- – only 1 to 5 million years old- – which makes it perfect for studying the early stages of planet formation.
Around these stars is a disk made of gas and dust, which is where planets begin to form.
The three stars in GG Tau A interact with each other and affect the disk of gas and dust around them, making it harder to predict how planets might form.
The forces between the stars could cause the disk to behave differently than in a system with just one star. This makes GG Tau A a perfect system to study how planets can form in more complicated, multi-star environments.
Significance: This is a rare setup in the universe, and studying it helps scientists understand how planets form in more complicated star systems.
It allows scientists to learn how planets could form in these more complicated environments.

Q1: What is a Protostar?

It is a dense and hot core at the centre of the collapsing cloud. It gathers surrounding dust and gas, eventually becoming the precursor to a fully developed star.
