Cosmic Corey: Is There Life Out There?

New Telescope Searches For Earth-like Planets

March will enter like a lamb, which means it's a great time to get out and look at the night sky!

Temperatures will be in the 60s and 70s for most of the first week of March with mostly clear skies. This is supposed to be the first official month of spring, but it feels like spring already sprung a few weeks ago along the Front Range!

While you use the calm weather to scan for stars and planets, NASA also plans to look at planets this month... outside our solar system.

NASA hopes to launch a new telescope that is designed to search for Earth-size planets in our galaxy. It's called the Kepler telescope and it was developed and built by Ball Aerospace & Technologies Corporation in Boulder.

A tentative launch date is scheduled for Friday, March 6. Once the telescope makes it into space, it will survey more than 100,000 stars in a nearby region of the Milky Way Galaxy.

It will look for planets that mimic the Earth's orbit around the sun. NASA says such planets would be in the "habitable zone," a region around a star where conditions allow water to be liquid on a planet's surface.

A Peek at the Planets:

If you get up early on Sunday, March 1, you can see four planets together about 35 minutes before sunrise! Mars, Mercury, Jupiter, and Saturn will all be visible in the ESE portion of the sky. If you miss Mercury, you won't get a chance to see it past March 2. The planet will sink in the horizon the rest of the month and disappear from view.

Jupiter will remain in the ESE and SE in the morning and creep higher as the month progresses. Mars will also stay in the ESE as it closes in on the Sun.

For the night star gazers, look for Venus in the western sky shortly after sunset. Saturn will also be visible in the east to ESE at dusk. It will reach its peak brightness for the year on Sunday, March 8.

The Moon in Motion:

First Quarter: Wednesday, March 4
Full Moon: Tuesday, March 10
Last Quarter: Wednesday, March 18
New Moon: Thursday, March 26

The full moon for March has an interesting name. It is known as the Worm Moon. Native Americans gave it this name because at the time of this spring Moon, the ground begins to soften and earthworm casts reappear, inviting the return of robins.

It is also known as the Sap Moon, because it marks the time when maple sap begins to flow and the annual tapping of maple trees begins.

From the History Books:

In the mid-1960s, the Soviet cosmonauts achieved an amazing first in space history. The Americans and Soviets both fought for space supremacy, but the Soviets were the first to complete a successful spacewalk.

Alexei Leonov accomplished the feat on March 18, 1965. While his crewmate, Pavel Belyayev, waited inside the Voskhod 2 spacecraft, Leonov became the first human to ever walk in the vacuum of space as he braved 10 minutes outside the craft's airlock.
