NASA stormy delay of the Artemis 1 moon mission, the Milky Way's hotspot and InSight lives on Mars!

Zodiacal light is a phenomenon that occurs when sunlight is scattered by interplanetary dust. Until the full moon on Oct. 9, this light will be visible along the eastern horizon in the predawn hours.

Scientists may have discovered when and how high-energy particles that bombard Earth emerge from violent environments, such as the sun's atmosphere.

The word equinox, from the Latin for "equal night," alludes to the fact that day and night are then of equal length worldwide on these dates. But this is not necessarily so.

An active sunspot that is just about to exit the visible disk of the sun shot its parting flare at Earth, causing a radio blackout in Africa and the Middle East Friday morning.

NASA's Perseverance rover has spotted a phenomenon scientists had lost hope of ever seeing on Mars.

The European sun-observing mission Solar Orbiter observed a mysterious "switchback" in the solar wind that might explain what propels particles from the sun across the solar system.

Solar storms can mess with Earth, but can they kick up a tsunami?

The Daniel K. Inouye Solar Telescope could change how we explore the sun and our understanding of hazardous solar flares.

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.

This is the spacecraft's 13th close approach to the sun, but its first in a new era of solar activity.

The sun-exploring Solar Orbiter spacecraft came face to face with a massive eruption of plasma from the sun, just ahead of a pivotal flyby of Venus.

Violent activity on the sun last week resulted in stunning views for observers in the northern hemisphere over the weekend.

Space weather watchers observed a series of powerful flares between Aug. 27 and Aug. 29, the most powerful of which registered as a moderate M8-class flare.

Auroras have been swirling through the skies already this week as the sun awakens from slumber.

Extreme solar storms can cause widespread disruption to our everyday lives, just like pandemics.

A new study explores what happens when blown-up dying red giant stars engulf planets in their vicinity.

International satellite services firm Intelsat has lost control of one of its broadcast satellites after it was presumably disabled by space weather.

A once-tiny spot on the sun's surface grew over the weekend to the size of Earth. It may end up launching some flares and solar eruptions our way.

For 400 years sunspots have been used to measure the sun's cycle, but a newly suggested 'circle of fifths' system could predict dangerous and violent solar events years in advance.
