There's a cool "close encounter" of worlds happening right on the horizon at sunrise on Saturday (January 29).
Assuming you can see low enough between buildings and trees, you can see the moon and Mars soar close to each other in the sky at just over two degree intervals.
They will not be alone in this close heavenly meeting in heaven before dawn; only a small piece to the left of you will be Venus, and if you want an observation challenge (and are equipped with binoculars), you can also see (dimmed) Mercury and (bright) Saturn a little further to the left.

But you have to act fast to see the worlds so close together: In New York City, Mars and the moon will be visible at 5:01 EST and disappear from sight in the bright sky at 6:48 EST, according to In- The-Sky.org.
Do you see the moon passing the planets?
If you take a photograph of the moon, Mars or Venus, let us know! You can send photos and comments to email@example.com.
Conjunctions occur in our sky thanks to the fact that the sun, moon and planets share a path across the sky known as the ecliptic, otherwise called the planet of our solar system. Several times a year you can see different worlds standing in line in the sky. Sometimes they even eclipse each other, which will happen next time in May during the "blood moon" lunar eclipse when the moon passes into the shadow of the earth.
Fortunately, most of the worlds visible in the sky should be visible to the naked eye this weekend: Mars in the order of 1.5, Venus in the incredible -4.3, and somewhat weaker Saturn in the order of 0.7. The moon will of course be quite easy to spot. For perspective, typical eyes can look up to the order of 6.0 under dark sky conditions.
Be sure to go out before sunrise, at least 20 minutes earlier, if you can, to let your eyes adjust to the sky. Protect yourself as best as possible from any men's lights nearby. If you need to consult a star chart or your phone, use a red filter to maintain your night vision. Skywatchers in cooler areas will also need to gather to observe before dawn.
More ambitious astronomers may take binoculars or a telescope rather than observe the conjunctions, though Mars and the moon will be too far apart to fit into a single telescope image.

If you miss this connection, NASA says not to fear: more are coming soon. "Mars will continue to brighten and climb higher over the next few months, where it will have super close connections with Saturn and Jupiter," the agency said.
