Solar Scientists Add Magnetic Polarity to the Sun’s Hidden Hemisphere

Researchers have developed a way to assign magnetic polarity to far-side solar active regions using helioseismic maps, a step that could sharpen space weather forecasting before trouble rotates into view.

Key Takeaways

Researchers developed a way to assign magnetic polarity to far-side solar active regions.
The method builds on helioseismic maps from NOAA’s Global Oscillation Network.

ALMA Spots Giant Gas Ring Around a Young Protostar, Offering New Clues to Star Formation

Researchers using ALMA have identified a warm gas ring about 1,000 astronomical units across around a deeply embedded protostar in Taurus, adding a new piece to the puzzle of how infant stars shed energy and keep growing

Key Takeaways

ALMA Band 9 observations revealed a warm gas ring about 1,000 astronomical units across around MC 27.
Researchers link the structure to magnetic flux associated with the protostar’s disk.
