Message from Sky & Telescope

The AAS staff (including staff of Sky and Telescope) are working remotely from their homes to support the social distancing efforts to contain COVID 19. While we are all working to support the S&T community, there may be delays in responding during this time. If you have a question or concern, please contact Camillia Taylor at [email protected].

This is a difficult time for the entire United States. Aero, our fulfillment partner, is based in Ohio. Aero provides fulfillment services for P&G. While they will continue to fulfill our orders, there may be a delay in shipping our products because they must give priority to medical, personal healthcare, and cleaning and sanitization products.

Sky & Telescope February 2021 Magazine

Format: Magazine

SKU# STM20212

In the February 2021 issue of Sky & Telescope, we reveal the final member of our bevy of new columns: First Exposure. To introduce this column, Sean Walker covers the basics of astrophotography for anyone who wants to start the craft. For more experienced astrophotographers, we have tips for photographing a whole collection of planetary nebulae, including a few with some fun nicknames. While planetary nebulae are the remnants of certain stars’ deaths, the wild story of the star T Tauri takes us back to their formative years. T Tauri has an entire class of stars named after it that it doesn’t quite match. Originally thought to be one star, then two, and now three, it’s discovery led directly to the historical realization that the universe is still creating new stars. But for every answer, astronomy has several more questions to take its place. For instance, how did our galaxy come to have two “bubbles” of high-energy radiation seemingly emanating from its center? While scientists are still debating what created these structures, they are starting to lean toward the Milky Way’s supermassive black hole as the culprit.
