In pursuit of understanding why the Sun's atmosphere is so much hotter than the surface, and to help differentiate between a host of theories about what causes this heating, researchers turn to NASA's Interface Region Imaging Spectrograph (IRIS) mission. IRIS was finely tuned with a high-resolution imager to zoom in on specific hard-to-see events on the Sun. A paper published in Nature on Sept. 21, 2020, reports on the first ever clear images of nanojets — bright, thin lights that travel perpendicular to magnetic structures in the solar atmosphere called the corona — in a process that reveals the existence of one of the potential coronal heating candidates: nanoflares.

There are 5 major discoveries the Parker Solar Probe made on the Sun. Parker's discoveries include evidence for a dust-free zone around the Sun, hearing the sounds of the solar wind and dust particles, magnetic switchbacks, and small-scale flares and space weather.

In 2009 the IBEX satellite detected an excess of atoms reflected back from a particular spot at the edge of the solar system that originally came from the Sun. To this day this echo, dubbed the "IBEX ribbon" is unexplained. Could it be something to do with the Milky Way's magnetic field? Or something more sinister that might affect future human exploration of the solar system? McComas et al.

Just like terrestrial storms, solar storms throughout the solar system and indeed, here on Earth. Impacts are wide-ranging, including the beautiful (e.g., the stunning auroral light shows) to the threatening (causing power grid failures and satellite destruction). Like Earth meteorology, we need to predict this space weather. However, space weather prediction lags its terrestrial counterpart by 50 years. Machine learning can help. Building on the work of past FDL teams, and using datasets from NASA’s Heliophysics System Observatory, as well as ground-based observatories, this FDL team will attempt to develop a machine learning model that will lead to a robust tool for predicting solar weather. Meet the team: Banafsheh Ferdousi (University of New Hampshire), Panagiotis (Panos) Tigas (Oxford University), Téo Bloch (University of Reading, U.K.) and Vishal Upendran (Inter-University Centre for Astronomy and Astrophysics, Pune, India)

ESA’s Solar Orbiter spacecraft has sent back its first images of the Sun. At 77 million kilometres from the surface, this is the closest a camera has ever flown to our nearest star. The pictures reveal features on the Sun’s exterior that have never been seen in detail before. Launched on 10 February 2020, the spacecraft completed its commissioning phase and first close-approach to the Sun in mid-June. Since then, science teams have been processing and examining this early data. The spacecraft is currently in its cruise phase, on its way to Venus, but will eventually get even closer to the Sun.

This Space Weather News forecast sponsored in part by Millersville University: https://www.millersville.edu/swen This week our Sun continues to keep us on our toes, albeit with subdued activity. We have a partly Earth-directed solar storm on its way that should graze Earth around the 27th. This storm might be intensified by some fast solar wind that should follow. However, it is doubtful any storming will be strong enough to cause much of a disturbance. Any aurora will likely be sporadic and only at high latitudes, so aurora photographers shouldnt get too excited. Also, a couple of promising bright regions have fizzled on the frontside of the Sun, resulting in the solar flux dipping back into the high 60s. Unfortunately, this means poor radio propagation on Earth's dayside, which is sad news for those emergency radio operators participating in the ARRL field day this weekend. The best news though is for GPS users, as the weak storming and low solar flux means GPS reception should be decent all over the globe. Learn the details of the grazing solar storm, the long, snake-like filament that didnt erupt, and what else our Sun has in store this week.

The Copernican Principle has been with us for centuries. It broadly states that "we are typical" but increasingly we are beginning to question this doctrine. One famous push back is the Rare Earth hypothesis, but testing this idea will take generations. What about our Sun? Surely here we should have a better understanding as to whether our star is typical or not. Join us as we discuss why the Sun might be more special than Copernicus ever imagined.

This Space Weather News forecast sponsored in part by Millersville University: https://www.millersville.edu/swen This week our star begins to look like it did back during more active times. We have multiple new cycle bright regions both Earthside and farside that are firing mini-solar flares and solar storms. In fact, one region on the farside just launched a large solar storm so we will keep an eye on it as it rotates into Earthview over this next week. We also have a small coronal hole rotating into the Earth-strike zone and it could bring some small pockets of fast solar wind causing weak aurora shows, especially at high latitudes. Solar flux stays in the marginal range this week on Earth's dayside while GPS/GNSS reception continues to look good all over the globe. See details of this new activity and learn about the serendipitous encounter between the disintegrating Comet ATLAS and Solar Orbiter and where both ATLAS and SWAN will be in the sky this week.

This Space Weather News forecast sponsored in part by Millersville University: https://www.millersville.edu/swen Space Weather gets a bit lively this week starting with some spectacular prominence action on the east limb of the Sun. In addition, our Sun launches a solar storm, which looks like it will go just to the west of Earth, but it could very well enhance the fast solar wind expected to hit over the next couple of days. Aurora photographers, especially at high latitudes could be in for a show. By far the biggest story this week is the appearance of two new bright regions in Earth view. Both of these regions could be signs of the new solar cycle, especially the northern hemisphere region, which has been putting on a nice display of coronal rain as it rotates into view. Although this region has launched several solar storms while on the Sun's farside, it seems to be dissipating now so we may not see much more activity from it. At least these regions are boosting the solar flux back into the marginal range for radio propagation so radio operators can enjoy a boost in propagation over the next few days. Learn the details of the coming fast solar wind, the near miss of the coming solar storm, and how the new bright regions on the Sun might affect you this week.

Life on Earth depends on the steady nature of our star, and an international team of scientists searched thousands of other stars to try to find out if the sun has always been as consistent as it is now. And According to a study published Monday in Nature Astronomy, scientists searching for habitable exoplanets should maybe be looking in some more exotic places. SciShow has a spinoff podcast!
