This captivating video explores Sedna, one of the most distant and mysterious dwarf planets in our solar system. Discovered in 2003, Sedna orbits the Sun once every 11,400 years, traveling through icy ...

A new model from a Florida Tech professor suggests how planets are formed may determine if they have water. The study proposes that some planets may be "born dry" because they lack a way to attract ...

The Copernican Principle, named in honor of Nicolaus Copernicus (who proposed the heliocentric model of the universe), states that Earth and humans do not occupy a special or privileged place in the ...

The solar system is a grand cosmic stage where each planet and moon plays a unique role in a story billions of years in the making. From Mercury’s shrinking surface and Venus’s runaway greenhouse ...

A recent study introduces a potential new candidate, dubbed Planet Y, inferred from the tilted orbits of distant objects in the Kuiper Belt.

In the hunt for extraterrestrial life, we usually look for planets orbiting sun-like stars and icy moons. But there is another possible candidate—planets circling white dwarfs, the hot, dense remnants ...

New research suggests that planets outside our solar system contain far less surface water than scientists once believed. Contrary to earlier theories that these exoplanets might be covered by deep ...

Previous research suggests that brown dwarfs should contain phosphine—which forms when phosphorus combines with hydrogen—given the conditions of their atmospheres. But past observers failed to find a ...

A new study suggests yet another theory for a possible extra planet in our solar system, likely of a size between Mercury and Earth. The authors dubbed it Planet Y.

Now a team of researchers, led by University of California San Diego Professor of Astronomy and Astrophysics Adam Burgasser, has reported the detection of phosphine in the atmosphere of a cool, ...

Astronomers using the James Webb Space Telescope are unraveling the mysteries of TRAPPIST-1e, an Earth-sized exoplanet 40 light years away that could harbor liquid water. Early data suggests hints of ...
