In January, stargazers will be able to see four bright planets, the close dance of Venus and Saturn, Mars at opposition, and ...

Using rotation velocities for stars in the globular cluster M13, we find that the required angular momentum for the fast rotators is up to 1–3 orders of magnitude (depending on some assumptions) ...

Subsequently, two additional formulas emerge: one for determining the average rotational period of celestial bodies such as planets in the Solar system, stars and neutron stars in the Milky Way system ...

It may be surprising to learn that we know the rotational period of all the planets in the solar system, even the most distant planet Pluto, with the exception of the planet that comes nearest to us, ...

The story of Earth’s atmospheric oxygenation is one of transformation, shaped by both biological and planetary forces. While ...

Therefore, astronomers might expect that all of the planets in the solar system would spin in the same direction as the sun. "To look at the direction of the rotation, we always compare it to a ...

Explore the wonders of our Solar System in an immersive 3D experience! Witness the rotation of planets around the Sun and their self-rotation in this interactive web-based application developed using ...

Exquisite data recently obtained by the space missions Cassini and Juno provide new constraints on the interior structure of our Giant planets Jupiter and Saturn. These data have revolutionised the ...
