A 12,000-mile-deep 'canyon of fire' has opened on the sun, spitting intense solar wind toward Earth
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. → Read More
The sun let out another flare and the photos are stunning
NASA's Solar Dynamics Observatory photographs the sun with 10 times the resolution of high-definition television. → Read More
Ash from Tonga volcano eruption reaches record altitude but climate cooling unlikely
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. → Read More
Solar storm may amp up northern lights before Christmas
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. → Read More
Astronomers capture sharpest images ever of Milky Way's heart
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. → Read More
Giant black hole inside a tiny satellite galaxy defies explanation
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. → Read More
This pair of merging black holes is the closest to Earth we've ever found
A pair of supermassive black holes that will soon become one has been discovered hiding in a nearby galaxy. → Read More
Earth's earliest water may have come from solar wind and space rocks
Samples from an asteroid collected by a Japanese probe suggest that Earth's water may have come from the sun. → Read More
TRAPPIST-1 solar system that's home to potentially habitable planets was not bombarded by rocks like early Earth
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. → Read More
NASA's DART mission has a sequel. How Europe's HERA will explore an asteroid impact aftermath.
The European 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, Dimorphos. It will even attempt to peek inside the asteroid duo in a scientific first. → Read More

A digital replica of Earth could help scientists better model the future of our planet and find solutions to problems wrought by climate change. → Read More
This mysterious comet's super-bright outbursts have astronomers puzzled
One of the strangest comets in the solar system has been erupting with unpredictable bright outbursts since late September and nobody knows why. An international observation campaign now wants to crack the mystery. → Read More
Scientists create most detailed map of Uranus' mysterious auroras
Scientists have imaged the whole globe of Uranus in the infrared part of the light spectrum for the first time, hoping to shed light on the planet's mysterious auroras and weird magnetic field. → Read More
Stinky 'mushball' hailstones on Uranus may explain an atmospheric anomaly there
A recent discovery of giant ammonia-rich hailstones, dubbed mushballs, on Jupiter might explain why Uranus and Neptune seem to have no ammonia in their atmospheres. → Read More

SpaceX Starlink satellites responsible for over half of close encounters in orbit, scientist says
SpaceX's Starlink satellites are involved in about 1,600 close encounters between two spacecraft in low Earth orbit every week. That’s about 50% of all such incidents. As the constellation grows, that proportion is expected to rise up to 90%, experts say. → Read More
