Hey Space Placers!
Ready for spring, yet? You do not have long to wait as the change in seasons astronomically occurs on March 20th at 7:21 p.m. EDT. I say “astronomically” because with the way our weather has been lately who knows what Mother Nature has in store for us. Notice the “EDT”? Yes, Eastern Daylight Time (EDT) begins on the 13th at 2 a.m.
All of this adds up to more daylight which is why we are now holding our public observing sessions at George Mason University (GMU) Observatory starting at 7:00 p.m., 9 March and then 8:30 p.m. on the 23rd.
These sessions are free and open to the public. I have been very happy to see a large number of families attending. I hope to see you there.

The Earth undergoes a change in seasons at the Vernal Equinox as spring occurs in the Northern Hemisphere and it becomes fall in the southern hemisphere. Day and night would be almost equal in length at this time were it not for daylight savings time. Our planet’s seasons occur due to the 23.5 degree tilt in our planet’s axis and our annual orbit around the Sun.

Mercury provides an excellent opportunity to be easily seen after the second week of March. Mercury will be passing near far brighter Jupiter in the western sky after sunset from the 13th to the 16th. Jupiter is the brightest object in that portion of the sky and is easily spotted. Once you have zeroed in on Jupiter look just to the right. The fairly bright “star” you see close to Jupiter is Mercury. Having a clear western horizon and binoculars will greatly enhance your view. I will be providing more information in my blog.
Speaking of Mercury, spaceflight and planetary exploration history will be made on the 17th when NASA and Johns Hopkins University’s MESSENGER spacecraft enters orbit around Mercury. This is the first time in history that this has happened. MESSENGER stands for MErcury Surface, Space ENvironment, GEochemistry, and Ranging, which highlights the scientific goals of the mission. MESSENGER has traveled almost 5 BILLION miles and 6 ½ years to get to this milestone. I can hardly wait to explore this planet via MESSENGER and the Internet.

Brilliant Venus continues to grace the morning sky low in the southeast about 40 minutes before dawn as the month begins. On the 1st and 31st the waning crescent Moon passes to the left of Venus. As the month progresses Venus will be getting lower to the horizon.
Mars cannot be seen.
Bright Jupiter is low in the west at sunset and remains visible until about two hours after sunset. The waxing crescent Moon passes to the left of Jupiter on the 6th. If you have binoculars or a telescope you can watch the four main moons of Jupiter change their position night after night.
Saturn rises in the southeastern sky about two hours after sunset as March begins and at sunset by month’s end. If you have a telescope be sure to check out the ringed planet.
New Moon is on the 4th, First Quarter Moon is on the 12th and this month’s Full Moon occurs on the 19th. This month’s Full Moon is called the “Full Worm Moon” in recognition of the beginning of spring and warmer temperatures. Last Quarter Moon is on the 26th.
Here are our down to Earth events for this month.
Open House at the Department of Astronomy at the University of Maryland, College Park Campus Observatory, will be at 8 p.m. on the 5th and the 20th.
