Over the weekend, we had record-setting lows in the Lehigh Valley.

While the nights have been chilly, the cold has lead to the best stargazing conditions we've had in months.

Cold air is dry air, and light travels easier in dry air, which is why the night sky looks so nice the past few nights.

This is also why the sky has looked so blue the last few days.

The have looked very blue the last few days because our air is drier than usual.

On Monday night*, here's what you can see:

The sunset is now in the 6 PM hour, toward the end of the 6 PM hour.

*While this article was written for Monday, September 21, you can still see all of these planets in the night sky. Saturday, October 3 is the next time to see the space station.

Jupiter and Saturn will be in the southern sky, and they'll be right next to each other. At dusk, Jupiter is the brightest object in the sky. Saturn is to the left of Jupiter.

Both are somewhat low in the sky. They set (dip below the horizon) around 1 AM.

Look for Jupiter and Saturn in the south sky.

Mars is spectacular. It's the brightest and biggest object in the night in the middle of the night (12-4 A.M.). You'll definitely notice its orange color. It's high in the southern sky then.

It rises in the east sky at dusk, and it's not as big. It still looks orange, though.

Mars is high in the south sky.

The International Space Stationwill cross over us again on Saturday, October 3 for four minutes at 7:43 P.M. It'll first appear in the west sky, near where the sun sets. Then, it'll travel low in the sky to the northeastern horizon. But, before it reaches the northeast horizon, it'll suddenly vanish!

The International Space Station flew over us on Monday, September 21 at 7:31 P.M. It looked an airplane, and it will look like that again on Saturday, October 3.

The International Space station will look like an airplane flying across the sky. It will have a smooth, steady motion. You'll know you saw it if it vanishes before reaching the horizon.

This happens because the International Space Station runs into the darkness of the Earth's shadow. We see the space station in the first place because it's reflecting sunlight.

If you want to see the space station, get the exact time for your community here. It's best to go out when it'll be in the sky for four minutes or longer.

The Moonis in the night sky right at sunset for only a few hours. It will set at 10 P.M. tonight, leaving very dark skies for the rest of the night.

If you see the moon, it'll be a crescent shape because we just had a new moon last week. The moon gets half full later this week.

Watch the International Space Station fly over you Monday night.
