This is HOPS-315, a baby star where astronomers have observed evidence for the earliest stages of planet formation. The image was taken with the Atacama Large Millimeter/submillimeter Array (ALMA). In ...

In a groundbreaking discovery, astronomers have, for the first time, observed the formation of a new solar system. Using a combination of data from the Atacama Large Millimeter/submillimeter Array ...

Short-lived radioisotopes such as aluminum-26 influenced early solar system heat, water retention and the formation of Earth-like rocky planets, according to meteorite analyses and models.

Our solar system is a smashing success. A new study suggests that from its earliest period — even before the last of its nebular gas had been consumed — Earth’s solar system and its planets looked ...

An international team of researchers has found a planet around another star whose orbit is steeply tilted from the plane of the star's equator, a finding that contradicts some theories about how solar ...

Researchers examine meteorites containing material from our Solar System's birth. Not exactly related to this story, but it reminds me of how awesome it is that most heavy metals (heavier than iron, ...
