ASSIGNMENT 2: ASTRONOMICAL IMAGES

For each Micro Observatory Robotic Telescope Network observation:

position: RA= 13h 24.9m Dec= -7 degrees 28 minutes located in constellation: Libra Distance= 600 million km (33 light minutes) at closest to the Earth Field of view: Normal Exposure time: 15.00 sec. Filter: Grey (ND4)

Hour Angle: -1h 40.4m

Comment on quality of observation: Micro Observatory is run by the Harvard-Smithsonian Center for Astrophysics Question: Why are some of the targets listed as “not up tonight”? Micro Observatory Robotic Telescope Network observation: Target name: Jupiter Type of object: Planet position: RA= 13h 27.3m Dec= -7 degrees 39 minutes located in constellation: Libra Distance= ...

Part 2. Recent and historical images of Mars

Historical Image of Mars. Website reference: http://www.fourthplanet.space/tag/christiaan-huygens/

Image info: Christiaan Huygens’ observational drawing of Mars shows a triangular feature which known today as Syrtis Major.

Telescope used: Huygens used a telescope created by himself (1655). It was a good 2-inch (5.1-cm) telescope of 10.5-foot (3.2-m) focal length and 50x magnification. (Sheehan)

Observer: Christiaan Huygens

Exposure time: Observations were taken over a number of weeks. Other relevant details: Huygens used results of his observations of Mars to measure Mars’ rotational period. He measured it as 24 hours (only one hour away from the rotational period of the planet recognized today). It should be noted that the most prominent and largest crater of the Mars was named after Huygens (14.0°S, 304.4° ...

Galileo Galilei (1564-1642) was an Italian physicist, astronomer, philosopher, engineer and mathematician. He was a critical figure in the scientific revolution of the 17th century. Galileo is perhaps most synonymous with the invention of the modern telescope which has since helped man to discover countless things about the universe. In regard to astronomy, Galileo is erroneously credited with the discovery of the first telescope. His contribution was carrying out massive improvements on the existing telescopes. In 1609, Galileo learnt about the spyglass which was crudely used in ordinary life to view distant places on the land. Galileo began to ...

1.Jupiter was the first. Giant lies just beyond the frost line. As the frost line accumulated great amounts of water via evaporation from infalling icy material, it created a zone of lower pressure that increased the speed of orbiting dust particles and halted their motion toward the Sun. As a result , the frost line acted as a barrier whice lead material to accumulate. This excess material coalesced into a huge embryo of around 10 Earth masses, which then began to grow rapidly by swallowing hydrogen from the surrounding disc, reaching 150 Earth masses in only another 1000 years and finally topping out at ...
