A small percentage of the population has aphantasia, meaning they're unable to visualize using their mind's eye. Learn about this condition and the neuroscience behind it.

Scientists are not sure how much metallic dust remained in the atmosphere after the most recent SpaceX rocket 'disassembly.'

We know very little about some parts of Earth's atmosphere.

The Indian lunar lander and rover entered hibernation in early September.

Stunning first videos from a new space-borne instrument designed to improve the monitoring of thunderstorms show the crackle of lightning over Europe, Africa and the Atlantic Ocean.

Venus is being hammered by wild space weather this week after a giant sunspot, not visible from Earth, expelled an enormous plasma burst toward the scorching-hot planet.

NASA's Juno Jupiter explorer's new image reveals features in the turbulent atmosphere of Jupiter in the same colors a human observer would see them.

The James Webb Space Telescope captured mysterious concentric rings around a distant star that astronomers are still working to explain.

Asteroid Bennu nearly swallowed the OSIRIS-REx probe when it touched down on the rock to collect a sample, revealing that the space rock's nature was much different than scientists had thought.

An engineering image acquired during testing of one of James Webb Space Telescope's instruments reveals hundreds of distant galaxies in the deepest ever glimpse into the infrared universe.

Filaments of plasma escaped from a fiery canyon that opened on the sun's surface on Sunday (April 3) and might bring more auroras to Earth later this week.

NASA captured another solar flare blasting from the same overactive sunspot that triggered radio blackouts and stunning aurora displays on Earth.

The volcanic eruption that destroyed a Polynesian island on Saturday injected ash into record altitude but won't cause any disruption to Earth's climate, experts said.

The James Webb Space Telescope has successfully deployed all five layers of its tennis-court-sized sunshield.

A solar storm that erupted from the sun on Monday (Dec. 20) may boost northern lights displays around the north pole just ahead of Santa's trip this weekend.

The deepest and sharpest images of the Milky Way's center have been obtained, enabling astronomers to estimate the mass of the black hole at the galaxy's heart with unmatched precision.

A tiny galaxy orbiting at the outskirts of the Milky Way appears to have a giant black hole at its center, comparable to that of the much larger Milky Way itself, and scientists don't know why.

A pair of supermassive black holes that will soon become one has been discovered hiding in a nearby galaxy.

Samples from asteroid Itokawa collected by a Japanese space probe suggest that Earth's water may have come from the sun.

Earthlike planets that dance in sync around a nearby dim star couldn't have been bombarded by space rocks in their early formative years like our planet was, a study suggests.

The Hera mission will follow NASA's DART asteroid-deflecting spacecraft to the binary space rock Didymos and detail the aftermath of DART's collision with the smaller of the two asteroids.

Comet 67P, which famously hosted the first-ever cometary lander in 2014, made its closest approach to Earth on Friday (Nov. 12).

A digital replica of Earth could help scientists better model the future of our planet and find solutions to problems wrought by climate change.

One of the strangest comets in the solar system has been erupting with unpredictable bright outbursts since late September and nobody knows why.
