A rocky planet beyond gas dwarfs in LHS 1903 indicates that planetary systems form in unexpected ways.

"The Solar Family" is an 11-minute educational film produced by Encyclopedia Britannica Films in 1936. It presents the evolution of the solar system through the lens of the planetesimal hypothesis, a ...

New work offers fresh evidence supporting the supernova shock wave theory of our solar system’s origin. According to one longstanding theory, our Solar System’s formation was triggered by a shock wave ...

We're starting to see just how exceptional our own solar system and its history is, as more exoplanets are discovered. A fourth exoplanet discovery in the LHS 1903 system made by ESA's CHEOPS mission ...

ALMA, located in the Chilean Atacama desert, is the most powerful telescope for observing the cool Universe — molecular gas and dust. ALMA studies the building blocks of stars, planetary systems, ...

Discover how a rare "kiss and capture" impact gave rise to the Pluto-Charon binary system, shedding new light on the evolution and motion of icy worlds in the outer solar system. (CREDIT: NASA) ...

New work from Carnegie’s Alan Boss and Sandra Keiser provides surprising new details about the trigger that may have started the earliest phases of planet formation in our solar system. It is ...

When you see art of our solar system as the planet orbit the sun, you may notice that Earth's orbit has a tilt. It is not a perfect circle. What's more, Earth is not the only planet that displays such ...

Jupiter is the largest planet in our solar system (so large, in fact, that some scientists think it might have even consumed other worlds), a gas giant so massive that it shaped the orbits and ...

Rocky planet found beyond two gas planets challenges current planet formation theories Discovery made using ESA's Cheops telescope around red dwarf star LHS 1903, 117 light-years away Planets orbit ...

Star TOI-6894 is just like many in our galaxy, a small red dwarf, and only ~20% of the mass of our Sun. Like many small stars, it is not expected to provide suitable conditions for the formation and ...

Billions of years ago, in the frozen edges of the solar system, a violent impact shaped one of space’s oddest pairs. Instead of a typical planet-moon setup, Pluto and Charon became a binary system.
