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 ...

Add Yahoo as a preferred source to see more of our stories on Google. Astronomers have spotted a planetary system being conceived from the swirl of gas and dust surrounding a star — giving us an ...

A vast star-forming cloud of molecular hydrogen that is one of the largest single structures in the sky has been discovered hidden near the solar system. The crescent-shaped cloud—which its ...

A newborn planetary system is forming around HOPS-315, a protostar (one that recently formed) that sits some 1,300 light-years away in the constellation Orion the Hunter. This star isn’t in the ...

Astronomers have spotted a planetary system being conceived from the swirl of gas and dust surrounding a star — giving us an unprecedented, real-time look at how our solar system would’ve formed some ...

Moon’s precursor planet, Theia, disappeared billions ago, leaving scientists no direct chemical evidence to support the hypothesis. Now a team of astromers in France, Germany and the United States ...

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 ...

Simulations reveal that Jupiter’s rapid growth disrupted the early solar system, creating rings where new planetesimals formed much later than expected. These late-forming bodies match the ages and ...

Illustration comparing the planets of the Solar System and the Sun on the same scale. The planets are shown to scale relative to each other but their distances are not. From left to right the bodies ...

Earth may owe some of its properties to a nearby star that blew up just as the solar system was forming. This pattern, which saw a supernova bubble envelop the sun and shower it with cosmic rays, may ...
