Astronomers have found a planetary system that seems to have formed inside-out. While most systems, like our own, have rocky planets closest to their star and gaseous ones further out, the LHS 1903 ...

Super-puff planets have stunned astronomers after an international research team discovered two giant worlds with densities so low they are lighter than cotton candy. The newly identified exoplanets, ...

A distant star system with four super-sized gas giants has revealed a surprise. Thanks to JWST’s powerful vision, astronomers detected sulfur in their atmospheres — a chemical clue that they formed ...

An artist's impression of the planetary system surrounding LHS 1903, a small red dwarf star cooler and dimmer than our Sun. (European Space Agency) (CN) — For decades, astronomers thought they had ...

An international team of astronomers has discovered a distant planetary system that challenges long-standing theories of how planets form. Across our galaxy, astronomers routinely observe a ...

Thanks to the discovery of thousands of exoplanets to date, we know that planets bigger than Earth but smaller than Neptune orbit most stars. Oddly, our sun lacks such a planet. That's been a source ...

Four planets orbiting a newly born star in our galaxy are so light that they have the density of polystyrene, and could provide a key missing link in helping us understand how the most common ...

An exoplanetary system about 116 light-years from Earth could flip the script on how planets form, according to researchers who discovered it using telescopes from NASA and the European Space Agency, ...
