Scientists who study comets are struggling to keep up with popular speculation that the interstellar object 3I/ATLAS was sent ...

In March, ESA's spacecraft Solar Orbiter had its first clear view of the Sun’s south pole. A first analysis has now been published. Huge cells of hot plasma cover the Sun and create the large-scale, ...

Comet 3I/ATLAS, the third confirmed interstellar object to enter the solar system, is prompting renewed scientific debate ...

Astronomers have revealed that the real center of our solar system isn't the sun. Gravity is playing a part in everything. The barycenter is the center.

A new report offers the latest confirmation of 3I/ATLAS and its interstellar origins, as scientists still debate over its unusual properties.

The workings of our solar system are roughly the same now as they have been for millions of years. Moons circle their planets, the planets circle the sun, the sun’s magnetic fields and sunspots wax ...

The gravitational influence of dark matter on stellar motions within galaxies, particularly the high velocities of stars in the Milky Way, is the primary evidence for its existence. This influence is ...

Jupiter is the fastest spinning planet in our Solar System, completing a rotation in less than 10 hours. This rapid spin influences its shape, atmosphere, and extreme weather patterns, including the ...

Astronomers have found that a weird space rock at the edge of the solar system is locked in a rhythmic dance with Neptune. The object, designated 2020 VN40, is part of a family of distant solar system ...
