As we head towards the end of the month comets dominate the pre-dawn skies and their flybys of neighboring planets offer observing challenges for early bird sky-gazers.
Also the moon plays with the stars and offers some amazing opportunities to track down constellations. Skywatchers should also be aware that comet ISON is waking up with lots of activity.
Comet ISON has increased in brightness tenfold in less than a week, thanks mainly to ice vaporizing off its surface and producing a super-long tail that stretches some 8 million kilometers into space. Look for it in the pre-dawn skies low in the east. But you have to hurry since it is heading for a close encounter with the Sun on November 28.
If you miss it now, don’t fret, because if predictions hold true, the best skyshow will be in December as ISON heads back to the outer solar system from where it came.
Get all your observing details for ISON and other sky events this week at my weekly skywatching column at National Geographic News.

Any backyard stargazer worth his or her salt will tell you that bigger is better when it comes to telescope size and one amateur astronomer in Utah is living the dream, having built a 70″ optical instrument.
While Guinness Book of Records has not officially taken a look at the monster scope, it looks like it may take the title of largest backyard telescope ever built by an amateur.
Check out my full story on this behemoth at National Geographic News.

In the Sahara, a team of scientists claim to have found the first evidence of a comet directly impacting Earth.
About 28 million years ago a comet exploded over Egypt, creating a 3600°F (2000°C) blast wave that spread out over the desert below. The fiery shockwave melted the sand, forming copious amounts of yellow silica glass scattered over 2,300 square miles (6,000 square kilometers) of the Sahara.
Polished into the shape of a scarab beetle, a large piece of this glass found its way into a brooch owned by the famed Egyptian boy king Tutankhamen.

New deep-sky images of the Milky Way’s central core reveal picturesque butterfly-shaped gas clouds left behind by dying stars called bipolar planetary nebulae.
And all appear to be mysteriously aligned with one another. Dozens upon dozens of these hauntingly beautiful stellar remnants are oriented in the same direction – despite being separated by many thousands of light years, and each exhibiting unique physical properties. Researchers are searching for how nature could come up with such a bizzare phenomena.

The most common, humble star in the universe could be a mecca when it comes to astronomers hunting for planets hospitable to life. That’s because a new study is suggesting that red dwarfs – stars that are smaller, dimmer and cooler than our Sun – may have twice as many planets that are in the habitable zone than ever thought. In fact the number of these worlds- ones that have just the right temperature to support liquid water – may number as much as 60 billion. And that’s just in our own Milky Way galaxy.
Read more about this amazing new finding and what impact it will have on exoplanet research in my new article for National Geographic News.
