Today:
Looking in the east as midnight approaches, the skies host two trios of vertically-aligned stars. To the right or south of east, a familiar trio marks the belt of Orion, rising a little earlier each evening. Meanwhile a temporary trio shines to the left of east, thanks to the pair of stars we call the Twins of Gemini, joined by the slowly brightening red planet Mars on a line directly below them. They reach high in the south by dawn tomorrow.
