A Search for Cosmic Dust on Earth, Capturing the Depths of the Night Sky, and Kepler's Dream of a Moon Landing

In February’s issue of Sky & Telescope, amateurs hunt down meteorites, teach readers how to capture incredible nightscapes, discover exoplanets, and build their own spectrographs. Author Howard Banich describes his quest to visually track and sketch the changes in NGC 2261, or Hubble’s Variable Nebula, every night. Soon, observers will also be able to also see Comet PanSTARRS (C/2017 T2), which will be visible even small telescopes by this February. Join Bob King as he instructs readers on where to find it. Speaking of the solar system’s smaller worlds, scientists have discovered that many of them are double worlds known as contact binaries. We detail what scientists have learned about these connected bodies from when they were first hypothesized in the 1970s up until New Horizons captured an image of Arrokoth during the first morning of 2019. Then take a look back in time (and to the future) with Johannes Kepler. Did you know Kepler wrote science fiction? Well, it’s fiction no longer. We feature his Somnium and its prophetic description of space travel. Finally, learn how to capture images of the night sky from city balconies, no, it’s not impossible!

Reading S&T on a web page With nxtbook is a very low quality and frustrating experience. It is difficult to expand and contract the print and to move around the page. You can do better!

I have not received my February Issue of S & T magazine. I have the January and I just got the March Issue in the mail today (Jan 18). It might have been lost in the holiday mail or my postal carrier might have lost it or delivered it to the wrong address or it get lost at your end. I would like to receive a replacement as soon as possible. Tom Reiland, Glenshaw, Pa.
