A key method of forming planets finally has observational evidence, thanks to a network of radio telescopes in the U.K. that have resolved the existence of a huge abundance of centimeter-sized pebbles ...

Scientists traced the Moon's parent planet Theia to the inner Solar System, solving a 4.5-billion-year mystery.

Moon’s precursor planet, Theia, disappeared billions ago, leaving scientists no direct chemical evidence to support the ...

For decades, scientists have studied how planets form by looking at young stars nearby, assuming that these environments could be representative of all star systems. However, as astronomers discover ...

In the swirling clouds of gas and dust that surround newborn stars, planets begin to form. These planet-forming disks are rich with clues about how worlds like Earth come to be. Until now, scientists ...

Pictures are the key to new insights in the field of astrophysics. Such images include simulations of cosmic events, which astrophysicists at UZH use to investigate how stars, planets and galaxies ...

Using the Webb telescope’s powerful Near Infrared Imager and Slitless Spectrograph (NIRISS) instrument, the team detected a ...

A new study led by UNLV scientists sheds light on how planets, including Earth, formed in our galaxy – and why the life and death of nearby stars are an important piece of the puzzle. In a paper ...

Stars form in massive clouds of gas called molecular clouds. As they form, they accrete gas from these clouds, and as the ...

Sometime in 2029, the European Space Agency is scheduled to launch its Comet Interceptor Mission. The Interceptor will wait ...

About 4.6 billion years ago, a celestial cloud collapsed, paving the way for our solar system to form. Then, a nebula with strong gravitational pull took shape, kick-starting the birth of the sun. But ...
