Six planets—including Venus, Jupiter, and Mercury—will line up in the sky. Here’s the best time to watch and where to find clear views.

New research using NASA’s James Webb Space Telescope examines the maximum sizes of gas giant exoplanets, measuring chemical compositions and formation processes in the HR 8799 system.

General relativity helps explain the lack of planets around tight binary stars by driving orbital resonances that eject or destroy close-in worlds. This process naturally creates a “desert” of detectable circumbinary planets.

On February 28, 2026, the evening sky will offer a rare celestial geometry: six planets of our Solar system will seem to gather in our visible portion of the starry vault. This "alignment,"

Planetary systems in the Milky Way galaxy tend to follow a particular pattern: rocky planets toward the center, closest to the host star, and gas planets toward the exterior. That’s how planets are organized around our sun, with rocky Mercury, Venus, Earth and Mars first in the lineup, followed by the gaseous Jupiter, Saturn, Uranus and Neptune.
