Dec 27 - Planet-Eating Star?

December 27 Planet-Eating Star? by:

Is the star RZ Piscium eating its planets? Astronomers knew this star was erratically dimming and brightening. They thought it might be young. Now they think RZ Piscium might be hungry. Astronomers spy a red giant's bubbling surface For the 1st time, astronomers have seen giant bubbles roiling up to the surface of a star beyond our solar system. Each great bubble is so huge it would extend from our sun to Venus. See brightest star Sirius at midnight on New Year's Eve Dog Star Sirius reaches its highest point in the sky around midnight every New Year. For this reason, it might also be called the New Year's star. Tonight … Planet Uranus in moon's glare The December 27 moon is close to the 7th planet, Uranus. The lunar glare glare will make it tough to spot, but notice stars nearby ... and come back when the moon is gone.

Tonight … Planet Uranus in moon's glare After the moon moves away, it'll take patience to locate Uranus in front of the constellation Pisces. A detailed chart will help, too.

Insights from an ancient Tibetan ice core A short film about an expedition to Tibet's Guliya Glacier, where scientists drilled a Stone Age ice core going back 600,000 years. Plus a report on what the ice core reveals. Tonight … How can I see the Southern Cross? A signpost of southern skies, but can be glimpsed from southerly latitudes in the Northern Hemisphere, too. That means you if you're in Hawaii, near Mecca in Saudi Arabia, Leon and Guanajuato in Mexico, or Hanoi in Vietnam … or further south.
