SUN

NOAA is currently monitoring a developing solar flare on the sun that might produce a coronal mass ejection.

NASA's solar satellite captures images of three comets from unknown origins flying in front of the sun.

The eclipse season for NASA's Solar Dynamics Observatory satellite has officially started.

GJ 504b is a gas giant planet that has a dark pinkish color due to its composition and formation.

An amateur astronomer photographed a light bridge over a newly identified sunspot, which suggests that it may emit a solar flare soon. The light bridge is estimated to be about 5,000 miles long, roughly equal to the diameter of Mars.

As temperatures continue to soar in Western Europe, authorities are urging residents to exercise caution due to a rising number of coronavirus cases.

Scientists created models to determine the number of exoplanets that could orbit a star within its habitable zone. They found that if there is no planet that’s as big as or bigger than Jupiter, it could have about seven habitable exoplanets.

Through the sunlight that bounced off the Moon during an eclipse, scientists used the Hubble Space Telescope to observe Earth's biosignature. The method could be used to search for potentially habitable exoplanets.

A sunspot on the Sun that's turning to face Earth might emit solar flares in the next couple of days.

A stream of solar wind from the Sun might hit Earth and cause geomagnetic unrest next week.

Researchers explained in a new study that a spacecraft made from carbon-based foam could be used to carry out interstellar travel.

Comet NEOWISE was photographed flying over polar lights in the sky after Earth was hit by a coronal mass ejection from the Sun. Astrophotographer Isaac Polanski of Michigan traveled to the Wilderness State Park to capture the stunning display.

A laboratory located beneath a mountain in Italy detected a particle produced by a rare type of nuclear fusion within the Sun.

A UFO expert reported seeing a massive cube-shaped alien vessel flying in front of the Sun in a photo taken by one of NASA's satellites.

NOAA detected a CME moving slowly away from the Sun that could hit Earth this week.

A report on geomagnetic storms identified Washington, D.C., and New York City as high-risk areas during solar events.

An object that looks like a tardigrade appeared on the surface of the Sun in the photos taken by NASA and the ESA's Solar Orbiter.

Researchers were able to identify 19 asteroids in the Solar System that originated from interstellar space.

NASA and the ESA's Hubble Space Telescope was able to take a photo of a new type of stellar nursery.

In a recent study, researchers explain how a tiny fish could help end painful bone conditions.

NASA’s robotic spacecraft was able to capture a new photo of a passing visible comet. The photo shows the distinct tails of the comet.
