Studying a coronal hole at the Sun’s south pole revealed intermittent flashes as these jets channeled energy into expelling plasma. The amount of them suggest they are responsible for launching a large fraction of solar wind material.

Tiny plasma jets spotted near the Sun’s south pole could be powering the solar wind, finds @esasolarorbiter 🔗esa.int/Science_Explor… #ExploreFarther #WeAreAllSolarOrbiters

Tiny jets are everywhere. Could they power the solar wind? science.org/doi/10.1126/sc…

Tiny jets of plasma are escaping the Sun's outer atmosphere! They are found by EUI telescope onboard ESA's Solar Orbiter and could be the long-sought-after source of the ‘solar wind’. A discovery published in a Science Magazine article. Read the news 👉astro.oma.be/en/solar-orbit…

What launches the solar wind? Chitta et al. examine extreme ultraviolet images and videos of the #Sun from ESA's Solar Orbiter. They identify numerous small-scale jets within a coronal hole, which release enough energy and plasma to supply the solar wind. science.org/doi/full/10.11…

How do these jets connect to the solar wind? Why weren't they observed before? And how do they relate to in situ measurements by other spacecraft? Ugarte-Urra & Wang discuss in a related Perspective. science.org/doi/10.1126/sc…

Using observations from the ESA's Solar Orbiter, researchers in Science have identified numerous small-scale jets within a coronal hole. These “picoflare” jets may be the source of the Sun's solar wind. 📄: scim.ag/3Rb #SciencePerspective: scim.ag/3Ra

On this week's #SciencePodcast🎙️, SarCrespi and @drkeithsmith discuss the ESA's Solar Orbiter, which provided data for a new Science study that suggests a source for solar wind. 🎧 Listen here: scim.ag/3SA

Simply floored. I am truly honored to receive the #AGU2023 SPARC Award. A special thank you to my nominators, to AGU (American Geophysical Union) Awards Committee, and to everyone in this wonderful #SpaceWeather community. Without your heart, grace, and camaraderie, none of this would have been possible.

Overpublishing puts enormous stress on students and PIs. And brings tons of money to publishers in STEM. A new study shows that the number of papers is increasing FASTER than the number of #PhD graduates. It’s an amazing work with very useful statistics. Huge kudos to the

The Sun’s poles are still terra incognita. This 👇 is the Sun’s south pole as seen by the ESA's Solar Orbiter spacecraft on 30 March 2022. By the end of 2025 the spacecraft’s orbit will be inclined enough that it will be able to target the solar poles with its telescopes and make

Everything you wanted to know about #Proba3 before this afternoon's Media Day: these two small spacecraft will fly in precise mm-level formation to eclipse the Sun, allowing sustained observation of its ghostly surrounding atmosphere, the 'corona'. Read more:

G5 storm!! The Kp index hit 9, which was never seen in previous solar cycle (24). The Dst index has also reached -350 nT, never seen in cycle 24. What if strong southward field and fast solar wind conditions persist? The Kp index may no longer be useful.

Nature grants us geo-effective CMEs by seeing and hearing very productive discussions during the IAU Symposium 388 "SOLAR & STELLAR CORONAL MASS EJECTIONS" iausymposium.zyrosite.com Although I fail to see auroras from where I am (Hyatt Place Krakow), I am extremely thankful.

Breaking space news: We have made our own solar eclipse in space! 🌘 Today, we release the first images from our Proba-3 mission, which flies two spacecraft in precise formation to create artificial solar eclipses in orbit. Using a powerful instrument called a coronagraph,
