An object eight times the mass of Jupiter may have swooped around the sun, coming superclose to Mars' present-day orbit ...

All seven of the other planets in our solar system are about to become visible at once in a great planetary alignment – here’s how to spot the celestial show ...

With the exception of Pluto, planets in our solar system are classified as either terrestrial (Earth-like) or Jovian (Jupiter-like) planets. Terrestrial planets include Mercury, Venus, Earth ...

A new study in astrophysics has found why some planets’ paths have certain peculiar features. The formation of the solar ...

Astronomers using the James Webb Space Telescope (JWST) have uncovered a planet so extraordinary it has defied all existing ...

The James Webb Space Telescope has revolutionized astronomy in just three years. A new project celebrates its impact on the ...

lasting perhaps a hundred million years and ending with four surviving terrestrial (rocky) inner planets. The largest ...

Whether or not the evolution of the planets and moons in the Solar System is typical for their class of objects is still unknown. A key element of this research theme is the search for small, ...

A planet-sized visitor possibly visited the solar system billions of years ago and permanently changed the cosmic neighbourhood by warping the orbital path of four outer planets of the system, a ...

Astronomers have discovered extremely powerful winds pummeling the equator of WASP-127b, a giant exoplanet. Reaching speeds ...

Because many close-matching simulations had the planet-like object swooping through the inner solar system, the researchers created an additional 10,000 simulations including the terrestrial ...

Astronomers have discovered extremely powerful winds pummeling the equator of WASP-127b, a giant exoplanet. Reaching speeds up to 33,000 km/h, the winds make up the fastest jet-stream of its kind ever ...
