CNN —The Solar Orbiter mission has discovered jets of material rapidly releasing from the sun’s outer atmosphere. An artist's concept shows the Solar Orbiter spacecraft circling the sun. The advanced instruments aboard Solar Orbiter, as well as NASA’s Parker Solar Probe, are helping to unlock the biggest mysteries that remain about the sun. The sun’s magnetic field is so massive that it stretches beyond Pluto, providing a pathway for solar wind to travel directly across the solar system. Solar Orbiter works in tandem with Parker Solar Probe, which is orbiting the sun on a seven-year mission after launching in August 2018.

☆ The sun’s activity is peaking sooner than expected

Every 11 years or so, the sun experiences periods of low and high solar activity, which is associated with the amount of sunspots on its surface. Over the course of a solar cycle, the sun will transition from a calm to an intense and active period. During the peak of activity, called solar maximum, the sun’s magnetic poles flip. A solar activity spikeThe current solar cycle, known as Solar Cycle 25, has been full of activity, more so than expected. The solar storms generated by the sun can affect electric power grids, GPS and aviation, and satellites in low-Earth orbit.

Ocean secretsA bioluminescent jellyfish is shown in an image taken during exploration of the Marianas Trench Marine National Monument. NOAA Office of Ocean Exploration/APThe deep ocean is an alien landscape that scientists have only just begun to understand. So much remains to be explored because reaching the bottom of the ocean is an incredibly difficult task. But the ocean depths have much to offer, including lifesaving compounds and the secrets of how life on Earth evolved. The event is nearly 10 months away, but people are already anticipating the total solar eclipse that will pass over Mexico, the US and Canada on April 8, 2024.

☆ A violent collision likely created the Geminids meteor shower

CNN —The Geminid meteor shower, which lights up the sky each December, is one of the most active and dependable celestial displays of the year. Now, astronomers using NASA’s Parker Solar Probe have gained more insight into the underlying cause of the Geminids. The meteor shower was first recorded in 1862 and appears to radiate from the Gemini constellation. The Geminid meteor shower streaks across the night sky over the Lhasa River in Tibet on December 14, 2022. It’s the first asteroid to be associated with a meteor shower, and it measures about 3.17 miles (5.10 kilometers) across.
