The Sun belted out strong solar flares two days in a row, as activity ramps up toward the next Solar Maximum, predicted for mid-2025.
On Saturday, February 11, a flare classified as X1.1 erupted from the Sun, while just a day before a different region on the Sun blasted out a X1.0 flare.

You’ve probably never seen our Sun look like this before. This bizarre image of old Sol is made from data produced by three different space telescopes, each observing the Sun at a different wavelength.

Using data from the Solar Dynamics Observatory, scientists have discovered new clues that could help predict when and where the next solar flare might blast from the Sun.
Researchers were able to identify small flashes in the upper layers of the corona – the Sun’s atmosphere – found above regions that would later flare in energetic bursts of light and particles released from the Sun. The scientists compared the flashes to small sparklers before the big fireworks.

Future historians might look back on this time and call it the ‘exoplanet age.’ We’ve found over 5,000 exoplanets, and we’ll keep finding more. Next, we’ll move beyond just finding them, and we’ll turn our efforts to finding biosignatures, the special chemical fingerprints that living processes imprint on exoplanet atmospheres.
But there’s more to biosignatures than atmospheric chemistry. On a planet with lots of plant life, light can be a biosignature, too.

Solar coronal jets are fast moving plumes of plasma that erupt suddenly from the polar regions of the Sun. Astronomers believe that these help heat up the solar corona, but the physics behind the formation of these jets is poorly understood. Recently a team of astronomers have used observations with the Solar Dynamic Observatory and the Solar Orbiter to discover that multiple intertwining magnetic fields that connect and reconnect can power these fast moving jets.

Even though our Sun is now a solitary star, it still has siblings somewhere in the Milky Way. Stars form in massive clouds of gas called Molecular Clouds. When the Sun formed about five billion years ago, other stars would’ve formed from the same cloud, creating a star cluster.
How many other stars formed in the cluster?

Dark matter continues to vex astronomers around the world. We see its effects in the clustering of galaxies and the gravitational lensing of light within galaxies, and it seems to comprise about 80% of the matter in the universe, but we still haven’t detected it on Earth. So what about at least detecting it in our solar system? That might be possible according to a new study in Nature Astronomy.

Our Sun is the very reason we’re alive. It provides warmth and the energy our planet needs to keep going. Now you can add photogenic to its illustrious résumé, as NASA recently photographed our giant ball of nuclear fusion doing something quite peculiar.

The Sun is active, dynamic, and occasionally violent. Unfortunately our view of the Sun is limited to a small handful of orbiting satellites and ground-based observatories. The Solar Ring is new proposal that hopes to radically change that picture by launching a trio of satellites around the Sun to give continuous, 360° panoramic images in real time. The observatory could revolutionize our understanding of our parent star.

The sun is currently sleeping. Its surface and corona are relatively quiet as it prepares to ramp up for an expected phase of high activity in 2025. This past October, the ESA’s Solar Orbiter was able to sneak in a close-up peak at the Sun as it slumbers.
