Scientists have discovered a rare six-planet system, HD 110067, where all planets orbit their star in perfect mathematical ...

Astronomers have unexpectedly discovered the heaviest Neptune-like planet yet — one more than four times the mass of our solar system's Neptune — yet it remains a mystery how the world might have ...

Warm Neptune-size exoplanets are not nearly as common as super-Earths or hot Jupiters — and we are now closer to finding out why. Our galaxy apparently has a dearth of Neptune-size worlds that orbit ...

Astronomers have discovered a rare planetary system that dances to a cosmic rhythm. Located 105 light-years away in the ...

Assuming you’ve accepted Pluto’s demotion, Uranus and Neptune are the two planets in our Solar System farthest from Earth. That distance means humanity is still learning a lot about them. Some of ...

Researchers have discovered a new planet the size of Neptune, approximately 32 light-years away from Earth. A new study, published in the scientific journal Nature, details the discovery of AU Mic b, ...

Planets having atmospheres rich in helium may be common in our galaxy, as per new theory based on data from NASA’s Spitzer Space Telescope. Researchers proposed that warm Neptune-size planets with ...

A team of astronomers has discovered a new exoplanet, christened Kepler-410A b. The planet is about the size of Neptune and orbits the brightest star in a double star system 425 light years from Earth ...

Astronomers have witness the formation of a gigantic storm on the surface of Neptune using the Hubble Space Telescope. This is the sixth storm scientists have witnessed on Neptune since first ...

Astronomers have observed a gigantic storm on Neptune so big it covers an area the size of Earth while testing a telescope on Hawaii. The huge storm is about 9,000 kilometers in length, or one-third ...

A Neptune-size planet beyond the solar system has telltale traces of water vapor in its atmosphere, making it the smallest exoplanet known to have the wet stuff yet, scientists say. Several massive ...
