A very small instrument has a big job ahead of it: measuring all Earth-directed energy coming from the Sun and helping scientists understand how that energy influences our planet's severe weather, climate change and other global forces.

Solar Orbiter's latest images shows the full Sun in unprecedented detail. They were taken on 7 March, when the spacecraft was crossing directly between the Earth and Sun.

Researchers from NYU Abu Dhabi's (NYUAD) Center for Space Science have discovered a new set of waves in the Sun that, unexpectedly, appear to travel much faster than predicted by theory.

Many coronal loops -- ropey strands of plasma that scientists have long thought existed in the Sun's atmosphere -- may actually be optical illusions, according to a new paper that challenges prevailing assumptions of what we know, and don't know, about the Sun.

Scientists developed a neural network deep learning technique to extract hidden turbulent motion information from observations of the Sun.

The ESA/NASA Solar Orbiter spacecraft has captured the largest solar prominence eruption ever observed in a single image together with the full solar disc.

Propelled by a recent swing past Venus, NASA's Parker Solar Probe is healthy and performing normally as it heads toward its next closest approach to the Sun on Nov. 21.

Twenty-five years ago, an enigmatic signal was discovered while analyzing the polarization of sunlight with a new instrument, the Zurich Imaging Polarimeter (ZIMPOL).

These motions were measured by analyzing 10 years of observations from NASA's Solar Dynamics Observatory (SDO).

Why The Sun's Composition Varies

About 17 years ago, J. Martin Laming, an astrophysicist at the U.S. Naval Research Laboratory, theorized why the chemical composition of the Sun's tenuous outermost layer differs from that lower down.

A hyper-sensitive instrument, deep underground in Italy, has finally succeeded at the nearly impossible task of detecting CNO neutrinos (tiny particles pointing to the presence of carbon, nitrogen and oxygen) from our sun's core.

Sunspots are darker regions which often appear on the Sun's surface. They are caused by strong concentrations of magnetic field, and can be as big as the Earth, or even much bigger.

Helium is the second most abundant element in the universe after hydrogen.

After four decades of searching, solar scientists have at long last found evidence of a type of seismic wave in our Sun.

Our Sun Experiences Seasonal Changes

The Sun undergoes a type of seasonal variability with its activity waxing and waning over the course of nearly two years, according to a new study by a team of researchers led by the National Center for Atmospheric Research.

The Orion Nebula is home to hundreds of young stars and even younger protostars known as proplyds.

Flux Ropes on the Sun

This is an image of magnetic loops on the sun, captured by NASA's Solar Dynamics Observatory (SDO). It has been processed to highlight the edges of each loop to make the structure more clear.
