Mars Forms Triangle With Moon and Star Tonight
As the evening twilight deepens around 8:30 p.m. local time Tuesday night (April 3), check out the southeast sky. Weather permitting, a waxing gibbous moon will be shining bright, but it won’t be alone.
Situated well above the moon will be two bright “stars.” I’ve placed the word stars in quote marks, because one of those stars is in reality a planet: the so-called Red Planet, Mars.
The planet will form a cosmic triangle with the moon, Mars and bright star Regulus. The arrangement can be seen in the sky map of Mars accompanying this planet viewing guide.

A Black Hole Overflows (NASA, Chandra, 2/2/09) (by NASA’s Marshall Space Flight Center)
NASA’s Chandra X-ray Observatory has helped create a spectacular view of Centaurus A that shows the effects of a supermassive black hole. At the center of this nearby galaxy, a central black hole powers jets and lobes that flare against a background of stars and stardust. In the upper left of the image, an X-ray jet extends about 13,000 light years away from the black hole. The material in that jet is travelling at about half the speed of light.
