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

A submillimeter survey of protostars

The formation of stars involves the complex interactions of many phenomena, including gravitational collapse, magnetic fields, turbulence, stellar feedback, and cloud rotation. The balance between these effects varies significantly between sources, and astronomers have adopted a statistical approach to understand the typical, early-stage star formation sequence. The earliest stage is called the protostellar stage. For low-mass stars (those with masses about that of the sun) this stage is usually separated into two subclasses as the star grows by accreting material from a massive envelope whose size can extend between five hundred and ten thousand astronomical units (AU) in a process that can last roughly half a million years. There are considerable uncertainties, however: some gas is ejected back into the medium in strong outflows, for example.
