If you could stand at the surface of Mars’ equator‚ you would feel like it is summertime at the bottom part of your body and wintertime at the top part! This is so because the temperature at the upper part of your body can be 0°Celsius‚ while that in at your feet can be 21 degrees Celsius. When it is snowing‚ the snow can vaporize before it reaches the ground. The place is a desert but a cold‚ cold one. Mars has so many impact craters on its surface‚ the largest of which is the Borealis basin.

Chemist named Glenn T. Seaborg discovered plutonium in 1941 at Berkeley University in California. The discovery of Plutonium was not announced until 1946 because America was at war with Japan and Germany. Plutonium was named after the planet Pluto‚ after the planet Neptune in the solar system and Neptune gave its name to Neptunium. <br><br>Plutonium is a silvery metal that turns yellow when exposed to air. It is warm to the touch due to the releasing radioactive energy from it. The atomic number

warming. There are three very important points that one needs to look at when discussing the issue of global warming. One is CO2 concentrations are not very high at all. The second is that solar cycles cause heating on not only earth but other planets. The last would be that global warming of the earth is a natural cycle that the earth goes through and has been going through for many years. It is very easy to get caught up in the global warming talk. One of the biggest issues is that of carbon

to orbiters and landers. Models of the solar system The planets and the Sun orbit the Earth in Ptolemy’s model. Our understanding of the universe has changed over time. Different civilisations have created different models to explain what the universe is and how the universe began. The Greek astronomer Ptolemy (c90-168AD) used measurements of the sky to create his geocentric model. This had the earth at the centre and all the planets and the sun orbiting around it. The geocentric model lasted

‘Is it more important to discover new ways of thinking about what is already known‚ then to discover new data or facts.’ To what extend would you agree with this claim? This claim can be interpreted in different ways‚ so it needs to be defined by what I personally believe it means in order to come to a conclusion. By the term ‘new ways of thinking’ I understand having the same information as before but finding a new way of seeing or using it. With the term ‘discover new data/facts’ I understand

that I left planet earth and embarked on one of the most important missions in NASA’s history. I should probably back up though‚ and explain to you how this came about. April 16th was sunny with only a few clouds in the sky‚ the smell of spring was in the air and with the end of second semester right around the corner‚ the quad was packed with people eager to catch some much desired sun rays. Unfortunately for me though I was stuck in astronomy. That day’s topic was our very own planet earth. Dr

Astronomy is the scientific study of celestial objects like stars‚ comets‚ planets and galaxies. It is derived from Greek words astron and nomos which mean ’star’ and ’law’ respectively. It is related with formation and development of the universe‚ motion of celestial objects‚ evolution‚ physics and chemistry.Since the 20th century‚ the field of astronomy has got divided into two branches: observational and theoretical. Observational astronomy emphasis on acquiring and analyzing the data by using

Then a few days later‚ Bob turned on the TV and then same ad came up that NASA’s astronauts found food on that mysterious planet and on that plant they found cheese and sauce wraps so NASA decided that they are going to name this planet Cheese and Sauce Mania. Bob got so excited about the news that he jumped out
