Did 29 Cygni b form like a planet, or like a star? Or are the two not quite as distinct as previously believed?

Far beyond the reach of any spacecraft, a distant world glows with heat so intense that rock itself turns to vapor. In that ...

Astronomers have unveiled the largest planet-forming disk ever observed around a young star, a sprawling structure where gas and dust are actively assembling new worlds. The discovery pushes the ...

A new experimental study published in Geochimica et Cosmochimica Acta reveals that Mercury’s sulfur-rich interior behaves in ...

An artist's impression shows the "inside out" planetary system around the star LHS 1903. - ESA An exoplanetary system about 116 light-years from Earth could flip the script on how planets form, ...

What can rocky planets orbiting in the outer parts of a solar system teach scientists about planetary formation and evolution? This is what a recent study published in Science hopes to address as a ...

Planets, like those in our solar system, form in a bottom-up process where small bits of rock and ice clump together and grow larger over time. But the heftier the planet, the harder it is to explain ...

Astronomers have discovered two gas giant exoplanets forming in a dusty disk around the young star, WISPIT 2. - ESO / C. Lawlor / R. F. van Capelleveen et al. composite image Astronomers are watching ...

Astronomers have found a planet-forming disk that looks like a solar system on steroids. New images from NASA's Hubble Space Telescope have revealed an enormous, oddly shaped disk of gas and dust ...

A giant planet in the HR 8799 system orbits six times faster than its neighbor, reigniting the mystery surrounding its origin ...

Astronomers have observed two planets forming in the disc around a young star named WISPIT 2. These observations, and the unique structure of the disc around the star, indicate that the WISPIT 2 ...
