IRDC G11.11-0.11
(Preview)
Something scary appears to be slithering across the plane of our Milky Way galaxy in this new Halloween image from NASA's Spitzer Space Telescope. The snake-like object is actually the core of a thick, sooty cloud large enough to swallow dozens of solar systems. In fact, astronomers say its "belly"...

T Canis Majoris
(Preview)
Observers have misidentified the semiregular variable T CMa over many years due to the use of charts with insufficient detail. A detailed chart is provided to allow for correct identification and it is also suggested T CMa may be non-variable and should be dropped from observing lists.
T CMa is lo...
