I live in Louisiana. Looking at the South night sky, there is a bright planet. At least, I'm assuming it's either Venus or Mars, not sure which. It's always noticable. It's the brightest object in the Southern sky now. What I'm asking about is just below and to the left of this object? I could swear it's pulsating a heck of a lot more than a star. It's got what it looks like red and white pulsating throbs to it. Very distinct. Bright. I haven't seen a star thats more pulsating. Does anyone know what it is?
