ABSTRACT:
The 1st January 2011 offered a very nice Astronomy event of proximity of Moon and the Planet Venus. The simultaneous record of the visible spectra of the light emitted by Moon and the Venus could be image captured in the same frame. The spectra have been analyzed and the intensity profiles obtained. The Saturn however is too feeble to observe and record the spectrum by the digital canon camera.
Introduction:
A. Facts about Planet Venus from Google Search:
* Diameter: 12,100 km. It is about 1040km smaller in diameter than Earth
* Temperature: Ranges from 900F+/- 50F (about 500°C +/- 32°C) at the surface
* Distance from Earth: At its closest, Venus is 41,840,000 km away
* Atmosphere: Carbon dioxide (95%), nitrogen, sulfuric acid, and traces of other elements
* Surface: A rocky, dusty, waterless expanse of mountains, canyons, and plains, with a 200-mile river of hardened lava
* Rotation of its axis: 243 Earth days (1 Venusian Day)
* Rotation around the Sun: 225 Earth days
* Magnetic Field: No
Venus is the brightest object in the sky besides our Sun and the Moon. It is also known as the morning star because at sunrise it appears in the east and evening star as it appears at sunset when it is in the west. It cannot be seen in the middle of the night. A Venusian day is 243 Earth days and is longer than its year of 225 days. Oddly, Venus rotates from east to west (retrograde - opposite to that of earth). If you were on Venus, the Sun would rise in the west and set in the east.Venus and Earth are close together in space and similar in size, which is the reason Venus is called Earth's sister planet. It's brightness is due to two things. Firstly it is quite close to earth compared to the other planets. Secondly it is highly reflective and a lot of sunlight bounces off the planet. Venus was once thought to be a tropical planet rich in vegetation. It was difficult to find out what the surface of Venus was like because it was always covered in cloud. The temperature at ground level was 840 degrees fahrenheit, the atmospheric pressure was 90 times that of earth and the atmosphere was highly corrosive. The extremely high temperatures on Venus seem to have been caused by the high quantities of carbon dioxide in the atmosphere which has lead to the greenhouse effect, so an understanding of our sister planet could have profound importance for the future of our own.
B. Atmosphere:
Possessing sulfuric acid clouds, the atmosphere of Venus is mostly carbon dioxide (96 percent), nitrogen (3.5 percent), and carbon monoxide, argon, sulfur dioxide, and water vapor (all less than 1 percent). The atmosphere is so thick and heavy that it bends light, making the ground appear to curve upward in all directions. The planet's atmosphere is ninety times heavier than Earth's. Orion the Hunter appears conspicuous in the eastern sky as twilight fades, and it grows even more prominent after darkness settles in. The star group climbs highest in the south around 11 p.m. local time, when it stands about halfway to the zenith from mid-northern latitudes. On 2nd Jan 2011this evening, Jupiter fits the bill perfectly. The brilliant planet lies just 0.6° due south of Uranus. If you center Jupiter through your binoculars, Uranus’ blue-green glow appears just to its north. Because both planets are drifting slowly eastward relative to the background stars of Pisces, they will remain close for most of January. So, if the weather doesn’t cooperate tonight, you’ll have more chances in the coming weeks.
Our Observations:
The simultaneous record of the spectrum of the Venus and the Moon within one frame of a digital image capture happens to be the NEW YEAR 2011 gift from this web Blog Dashboard. Other morning observations are presented below.
