Scientists believe that two asteroids might be fragments of long-lost "planetary embryos" from the early solar system.

Predictions are uncertain, but the solar system may be pushed farther from the galactic core or even ejected entirely from ...

For the first time, astronomers have imaged dozens of belts around nearby stars where comets and tiny pebbles within them are ...

Canadian astronomers have taken an extraordinary step in understanding how planets are born, using the James Webb Space ...

Two exciting new studies detail the life-supporting contents of a 4.3-ounce sample of the asteroid Bennu. The OSIRIS-REx ...

All of our solar system’s planets are lining up to parade through the night sky at once. This extraordinary celestial event will see the sky scattered with seven visible planets in what is known ...

While not a detection of life itself, this study shows that the Solar System may have been far more conducive to life in its distant past then we previously believed. Some 4.5 billion years ago ...

Jan. 15, 2025 — New observational data and simulation models have confirmed a new type of planet unlike anything found in the Solar System. This provides another piece of the puzzle to ...

Harvard and Smithsonian (CfA), and its Submillimeter Array (SMA), were critical for identifying a cache of belts surrounding other stars beyond the sun where comets may reside. Regions around 74 stars ...

An object eight times the mass of Jupiter may have swooped around the sun, coming superclose to Mars' present-day orbit before shoving four of the solar system's planets onto a different course.

This may explain the strange properties of the orbits of our solar system's planets, which are not quite perfectly circular, and all lie on slightly different planes. NASA artist’s conception of ...

A NASA satellite that suddenly reappeared after going silent gets credit for the remarkable discovery—a pair of temporary ...
