The mysterious 3I/ATLAS comet is hurtling towards Earth and is set to make its closest approach on Friday, December 19, with psychic Uri Geller claiming aliens aboard could already be among us

Scientists using NASA’s James Webb Space Telescope have observed an entirely new type of exoplanet whose atmospheric composition challenges our understanding of how this type of planet forms. This bizarre, lemon-shaped body, possibly containing diamonds at its core, blurs the line between planets and stars.

With 3I/ATLAS days away from making its closest approach to Earth, agencies worldwide are conducting the largest and most extensive planetary defense drill — with the goal of protecting ourselves against future threats from beyond.

NASA’s Mars Reconnaissance Orbiter (MRO) officially went into service above the Red Planet in November 2006. The spacecraft has since spent nearly 20 years circling Earth’s closest neighbor, studying its geology and identifying icy evidence of a once watery world.

NASA launches TRACERS satellites to reveal how solar energy penetrates Earth's magnetic shield and triggers space storms.

TRAPPIST-1e, an Earth-sized world in the system’s habitable zone, is drawing scientific attention as researchers hunt for signs of an atmosphere—and potentially life-supporting conditions. Early James Webb observations hint at methane,

In the spirit of the season, the interstellar comet 3I/ATLAS is changing color as it leaves the sun behind — shifting from a reddish tint to a faint green glow. That visible change signals the comet is reacting to solar heat and releasing new gases in space,
