Scientists from MIT and their colleagues have estimated the lifetime of the solar nebula — a key stage during which much of the solar system evolution took shape. This new estimate suggests that the ...

Our Solar System is believed to have formed from a cloud of gas and dust, the so-called solar nebula, which began to condense on itself gravitationally ~ 4.6 billion years ago. As this cloud ...

Tiny shavings from a single meteorite could completely overturn our understanding of how the solar system formed, after the space rock turned out to be older than expected. Previous research suggests ...

Learn about the formation of the grains within many meteorites, emerging from collisions of planetary bodies in the early ...

As our solar system formed, tiny particles in the disk around the young Sun gradually grew larger until they became the size of small pebbles. "Once pebbles grow large enough to no longer travel along ...

Based on the composition of gases spewed by the icy space rock, researchers estimate that our guest might be up to 12 billion years old—about three times the age of the solar system ...

Stephen has degrees in science (Physics major) and arts (English Literature and the History and Philosophy of Science), as well as a Graduate Diploma in Science Communication. Stephen has degrees in ...

For the first time, scientists have observed planets forming around a star other than our sun. Researchers used the James Webb Space Telescope and ALMA to observe planet-building material forming near ...

Two massive planets may have once existed in early solar system before being ejected, leaving behind evidence in unusual ...
