Scientists have confirmed the existence of over 6,100 planets beyond the Solar System in the Milky Way. Something that has ...

Astronomers have discovered an alien world that defies every planetary rule with its massive size, low density, and tilted ...

Astronomers from the University of Warwick have discovered an exoplanet they are calling NGTS-10b. This world has the shortest orbital period of any exoplanet known, completing a full rotation around ...

Warm Jupiters are rewriting the rules of planet formation - showing eccentric orbits that stay strangely aligned with their ...

Scientists have long puzzled over why all of the planets in Earth’s solar system have slightly slanted orbits around the sun. But a new, Yale-led study suggests this phenomenon may not be so unusual ...

A newly discovered system of six planets circling a nearby Sun-like star may be the key to unlocking how planetary systems form. All between the size of Earth and Neptune, the worlds are orbiting in a ...

The orbital period is the time taken for a planet to make one complete circuit of the star. So, for example, two planets orbiting a star would be in a 2:1 resonance when one planet takes twice as long ...

The solar system still has only eight confirmed planets that are orbiting the sun. It recently had nine planets, but it all changed after NASA and other space agencies decided to demote Pluto to a ...

A new study has challenged a popular explanation for the unexpected 30-second shortening of Dimorphos's orbital period. The ...

The newly identified world, named TOI-4507 b, is located around 578 light-years away and orbits a remarkably young star ...

Astronomers from the University of Warwick have observed an exoplanet orbiting a star in just over 18 hours, the shortest orbital period ever observed for a planet of its type. Astronomers from the ...
