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"...

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...

Title: The Carina-Near Moving Group Authors: B. Zuckerman, M.S. Bessell, Inseok Song, S. Kim We identify a group of ~20 co-moving, mostly southern hemisphere, ~200 Myr old stars near Earth. Of the stars likely to be members of this Carina-Near Moving Group, in either its nuc...

Thanks to the unique possibilities offered by ESO's Very Large Telescope Interferometer (VLTI), astronomers have solved a 140-year-old mystery concerning active hot stars. They indeed show that the star Alpha Arae is spinning almost on the verge of breaking and that its disc rotates the same way...
