The constellation of Capricornus, the Sea Goat, reaches its best visibility for the year tonight. Rising at sunset and setting at sunrise, it’s visible throughout the entire night and can be seen over the southern horizon around 1 a.m. (or midnight, if your area is not observing summer time.)
If you have a pair of binoculars, take a look at Alpha Capricorni. You should easily be able to see two creamy coloured stars; this pair is known as an “optical” double because they only appear close to one another. In reality, they are hundreds of light years apart.
