The next couple of weeks will see a nice alignment of the planets Venus, Saturn and Mars, in the dawn sky .
All three planets are bright enough to see with the naked eye, and over the next few days, they will joined by the Moon, which should make for an appealing photo.

There is Full Moon tonight. (04:52 UT, October 26).
And the moon in its orbit around the earth will be at the closes position to the earth (eg at perigee). This will make the full moon appear to be the largest full moon this year.

Rolling out of the sack, throwing on some clothes, and checking out the predawn star-filled sky this month is well worth losing sleep over.
You can grab a cup of coffee, but I think just gazing into the heavens will give you enough of a jolt. The stunningly bright winter constellations that we see in the evenings during the season are now putting on a preview.
I think they're the best in the heavens, with the bright constellation Orion the Hunter as the centerpiece of the delights. There are also three planets visible to the naked eye in the morning sky right now, as well as a meteor shower. You've got a lot to take in.

It was "the sound that forevermore separates the old from the new," the NBC radio announcer said on the evening of Oct. 4, 1957. And it could be heard by anyone in the world with a shortwave radio tuned to 20.07 and 40.002 megahertz. The "beep, beep, beep" of Sputnik marked the arrival of the Space Age.

This week we pass an anniversary of a significant milestone in space exploration. It was Oct. 4, 1957, when the Soviet Union launched Sputnik I. It was the first artificial satellite put into orbit around our Earth.
That was just 50 years ago. Many of us remember where we were and whom we were with as we scanned the night sky for a glimpse of Sputnik.
This is a good week to look for the dimmer constellations because our moon is rising later and is reflecting less sunlight in the process.

Finnish star-gazer discovers meteor shower - tail of new comet pinpointed
Meteor shower could be sign of comet that could come dangerously close to earth
Jarmo Moilanen, a municipal computer expert and amateur astronomer in the Finnish community of Vaala, has detected a new shower of meteors in the tale of a hitherto unknown comet.
