The magnetic classification is associated with solar flares—thankfully they're unlikely to be disruptive.

The structure is a solar prominence—a huge loop of plasma that can be tens of times larger than the Earth.

A sudden and intense radio signal detected in deep space has puzzled scientists, who suspect it may have come from a super-dense star.

The free web tool allows users to see just how detailed the new James Webb Space Telescope image really is.

Another solar eruption could also be about to sideswipe our planet today.

Black holes are regions of spacetime where gravity is so extreme that nothing, not even light, can escape.

Black holes are regions of spacetime where gravity is so extreme that nothing, not even light—the fastest thing in the universe—can escape.

While the Earth's magnetic field largely protects us from radiation and charged particles from the sun, space weather phenomena can impact our planet.

Astronomers say they're close to solving a years-old solar mystery after an up-to-date assessment of the sun's chemical make-up.

Fortunately the M-class solar flare was not strong enough to be disruptive for us on Earth, though its bright flash was clear to see for NASA cameras.

The Earth will pass between the sun and the moon this weekend, casting a red shadow over the full moon.

The supermassive black hole, which weighs as much as 4.3 million suns, is only the second ever to be imaged.

The announcement could feature an important discovery about our galaxy's supermassive black hole, Sagittarius A*.

A region of the sun that has only just rotated into view was responsible for a huge solar flare earlier this week associated with a radio blackout warning.

For decades scientists have observed a universe that seems set to expand forever—but this won't necessarily be the case, say others.

The group of dark blots on the sun's surface are areas of intense solar activity that could flare towards our planet.

The two colossal black holes, 9 billion light-years from Earth, orbit each other once every two years and will have a highly energetic collision when they meet.

Imagery of the eruption was captured by the Solar Orbiter spacecraft's "Full Sun Imager," which was designed to observe the full solar disc, even during close flybys of the sun.

Researcher Martijn Oei didn't know how impressive the 16 million light-years long galaxy was until another expert told him: "Congratulations, this is the largest radio galaxy ever found!"

Scientists found evidence of the previously unknown solar storm after analyzing ice cores from Greenland and Antarctica.

The Falcon 9 rocket stage, which has spent almost seven years in space, is expected to hit the moon at around 5,700 mph in March.

The burst of solar energy erupted from the sun on Thursday morning and was strong enough to potentially disrupt radio communications.

The telescope is headed for a point where gravity will balance its orbital motion, locking it in almost perfect unison with the Earth's orbit around the sun.

The map is only 10 percent finished, and scientists hope it will help them unlock mysteries about dark energy and the fate of the universe.

The hulking asteroid, more than 3,300 feet across, will speed past Earth at around 45,000 miles per hour on Tuesday.

The students came across the highly energetic cosmic event while scanning through decades-old telescope data.

The $10 billion dollar space telescope—the largest and most powerful ever built—promises to revolutionize our understanding of the universe.

This type of highly dense star can produce the most intense magnetic fields in the known universe.

Decades in the making, James Webb will also help us to understand what the universe was like a few hundred million years after its birth.

The powerful explosive event, nicknamed "The Cow," was 100 times brighter and faster than a regular supernova.
