A stunning new image released this week has captured a towering plasma prominence rising from the edge of the Sun. Recorded by the ESA and NASA Solar Orbiter mission, the scene shows a ribbon of glowing plasma twisting above the solar surface. This latest observation gives astronomers a clearer look at how the Sun’s magnetic fields shape the behaviour of hot gas in the outer layers of our star.
What exactly is a solar prominence?
A solar prominence is a large loop or sheet of plasma held in place by magnetic fields that extend from the Sun’s surface into its atmosphere. Although they look graceful and slow in images, prominences are enormous structures. Many of them reach heights several times larger than Earth.
These prominences form when magnetic fields trap ionised gas and hold it high above the surface. The plasma glows brightly because it is heated to thousands of degrees, making it visible even from millions of kilometres away.
The prominence captured this week appears dark against the background due to the imaging technique used, which highlights cooler plasma suspended above the hot solar atmosphere.
Why this new solar prominence image is important
Every high resolution observation helps scientists understand how the Sun’s magnetic fields rise, twist and reconnect. These magnetic processes drive much of the Sun’s space weather, including solar flares and coronal mass ejections. Each event can influence the space environment around Earth by creating auroras, disrupting satellites or interfering with communications.
This prominence shows complex magnetic activity just above the solar limb. By studying its shape, motion and behaviour, researchers can model how energy builds up inside the Sun’s magnetic network. These models help predict future solar events during the ongoing solar cycle, which is currently near its peak.
What the prominence tells us about the Sun in 2025
The Sun is moving through a very active phase of Solar Cycle 25. Over the past year, scientists have recorded more flares, sunspots and eruptions than early predictions suggested. This new prominence is another sign that the Sun’s magnetic field is highly energised.
Observing these events is especially valuable now because the cycle is near maximum activity. Each new prominence helps paint a clearer picture of the Sun’s changing behaviour and its impact on the wider Solar System.

A reminder of the Sun’s dynamic nature
The latest prominence image is a beautiful reminder that the Sun is not a calm, steady ball of light. It is a restless and constantly changing star where magnetic forces shape spectacular structures. As Solar Orbiter continues to capture detailed observations, we will gain a deeper understanding of our star’s rhythms and how they affect life throughout the Solar System.
