Keeping track of aurora forecasts, notifications, and community reports.

Did you see the Northern Lights (Aurora Borealis) visibility from last week if you were on that area? If you missed it and want to know more then there are some places where you can get reliable information: 1. Aurora Forecast Websites: Websites like the Space Weather Prediction Center (SWPC), Aurora Service, and the University of Alaska Fairbanks Geophysical Institute provide forecasts and updates on Aurora Borealis activity and visibility in different regions. 2. Mobile Apps: There are several mobile apps available for both iOS and Android devices that offer real-time updates, notifications, and forecasts for the Northern Lights. Examples include My Aurora Forecast & Alerts, Aurora Alerts, and Aurora Watch. 3. Social Media: Platforms like Twitter, Instagram, and Facebook have dedicated Aurora Borealis enthusiast groups, pages, and accounts that share updates, photos, and sightings. Following these accounts can keep you informed about recent Northern Lights activity. 4. Astronomy

Neutron star with measured at 11 kilometers radius

An international research team led by members of the Max Planck Institute for Gravitational Physics (Albert Einstein Institute; AEI) has obtained new measurements of how big neutron stars are. To do so, they combined a general first-principles description of the unknown behavior of neutron star matter with multi-messenger observations of the binary neutron star merger GW170817. Their results, which appeared in Nature Astronomy today, are more stringent by a factor of two than previous limits and show that a typical neutron star has a radius close to 11 kilometers. They also find that neutron stars merging with black holes are in most cases likely to be swallowed whole, unless the black hole is small and/or rapidly rotating. This means that while such mergers might be observable as gravitational-wave sources, they would be invisible in the electromagnetic spectrum.
