Today I am going to tell you about famous astronomer Galileo Galilei. Galileo was first born on 15th of February 1564 in Pisa, Italy and he died on 8th of January 1642 Arcetri, Italy. Galileo didn’t invent the first ever telescope but he did invent his own telescope which assisted him with finding Saturn and Jupiter. Galileo didn’t only find Jupiter but as well as 4 of its moons. Galileo also found out about Saturn’s rings but he thought of them as ears. In 1632 Galileo published his theory, Galileo’s theory was that all the planets revolve around the sun but many didn’t believe him. Neptune is the 3rd biggest planet in our solar system it has a radius of 24,622 km and a diameter of 49, 500 km. Neptune is the 17.15x the size of earth. Neptune …show more content…

The temperature on Neptune is a lot colder than our planet with an effective temperature of -214°C and an average temperature of -201°C but it isn’t as cold as Jupiter! Jupiter can get a temperature of -234°C and also it can warm down to a temperature of -145°C. Neptune has also got a extremely active climate and it will change temperatures much quicker than we would on earth. Neptune & Earth are different in many ways such as size the size of Neptune compared to Earth is 3.9x bigger. Mass can also be a big difference, the mass of Neptune is 1.02x 10^26 kg or you could say 102,000,000,000,000,000,000,000,000 where as earth is 5,972,000,000,000,000,000,000 or 5.972x 10^24 that’s a total of 57 Earths into NEPTUNE with extra room! The days on Neptune are quite short as they are only 16 Hours and 6 minutes. The volume of Neptune is a total of 6.3 x〖10〗^13 km^3 where as Earth is 6.37 x 106 m. On Earth as we know a year is 365 days/one year but on Neptune one full year is 164.79 Earth years. On Neptune they need a source of energy and water to contain a source of life. It would be microbial life but it will still be life. Kilometres below the surface of Neptune there may be water but it isn’t classified …show more content…

It would be microbial life but it will still be life. Kilometres below the surface of Neptune there may be water but it isn’t classified yet. Scientists think that there may be potential life on Neptune and it is unknown still to today. Neptune’s thought of life remains a mystery now and for a while.

Neptune’s thought of life remains a mystery now and for a while. Neptune’s rings are named after its founders/discoverers. There names are Galle, Le Verrier, Lassell, Arago and Adams. Neptune is one of 4 planets with planetary rings. Neptune’s rings were only identified and defined in 1989 but in the 1900’s they thought they were rings but couldn’t be sure it was. The first ring was discovered a little before this in 1968 and they were unable to confirm that it was a full ring! Neptune’s rings are way better than Uranus, Saturn &

Bacteria may travel for a lengthy amount of time before crashing randomly with other planets or disks. If met with ideal conditions on a new planets’ surfaces, the bacteria becomes active and the process of evolution begins. In natural science, abiogenesis is the natural process by which life arises from non-living matter, such as simple organic compounds. It is a study of how biological life processes, and the method by how life on how Earth arose.

Not only is NASA conforming to the Outer Space Treaty of 1967, but they are doing a favor to the supposed life on Mars, as “The environment on mars potentially is basically one giant dinner plate for Earth organisms.” That being said, even if life is not found on Mars, we ought to keep it healthy in case people discover a way to live on the planet. Another reason as to why we should prevent as many microbes as possible from dwelling on Mars, or any planet, is that we would not be able to accurately study the planet when covered in Earth microbes. The planets are very different from Earth; however the more microbes from our rovers and satellites inhabit these places, the more they become similar to

According to space.com Charon, Pluto’s moon is about half the size of pluto. Also that the dwarf planet Eris is 27% more massive than Pluto. According to the International Astronomical Union for a something to be a planet it has had cleared a path in its orbit. Pluto hasn’t done that which means it can’t be considered a planet anymore. Pluto is very small considering a country on Earth is bigger than a now dwarf planet.

Neptune, named after the Roman god of the sea, is the furthest planet from the sun, and the smallest gas planet in diameter. Neptune's mass is much larger than its size though, it is the third largest planet in mass, but the fourth largest in size. It has a circumference of 96,685 miles. It takes 165 years to travel around the sun. That's 34 years older than the recorded for longest living person.

These “building blocks of life” were found by NASA scientist’s Stardust spacecraft (Kaufman). These compounds could organize into self-replicating forms and even possibly organisms. Amino acids on rocks may seem insignificant because their occurrence is not uncommon in space, however some microorganisms like the chemolithoautotrophs can live on inorganic energy sources like minerals (NASA). By using information about extreme organisms on earth, scientists can compare their development with organic compounds found on space surfaces, and maybe discover how life

Hook: Pluto is the only dwarf and farthest planet we know in our solar system. Because Pluto is so small, scientist argue on whether or not it should be a planet. What makes Pluto, so special is the size of it and what’s known as a ‘Dwarf Planet’. Pluto was created by pieces around it just like all the other Dwarf Planets as well. I believe that Pluto should be categorized as a planet.

Abstract: Connecting what we viewed in the episode Life’s Rocky Start from the series NOVA with the chapter Can A Planet Be Alive in the book Earth in Human Hands Shaping Our Planet’s Future by David Grinspoon both help us understand the relationship between our planet and life. We come to the conclusion that our planet Earth is completely responsible for the creation of life. Through these astonishing new discoveries discussed in our sources we interpret the interactions between biotic and abiotic world of planet Earth.

Mars is said and proven to be the planet that is most like Earth. However, for many people who are not well educated on the topic they question it and don’t believe it for a second. Not because they don’t trust the astronomers and researchers but because they are unable to see the similarities from the service.

Uranus is the seventh planet from the Sun. It has the third-largest planetary radius and fourth-largest planetary mass in the Solar System. Uranus is similar in composition to Neptune, and both have different bulk chemical composition from that of the larger gas giants Jupiter and Saturn. For this reason, scientists often classify Uranus and Neptune as "ice giants" to distinguish them from the gas giants. Uranus's atmosphere, although similar to Jupiter's and Saturn's in its primary composition of hydrogen and helium, contains more "ices", such as water, ammonia, and methane, along with traces of other hydrocarbons.[11]

But when Pluto cuts through Neptune it turns into the 9th planet from the sun, and if you include Ceres (dwarf planet) it will be the 9th planet to the sun too. Neptune name is the Roman god of the seas. In the greek version the god name is Poseidon. People call it the “blue planet”. Neptune is the windiest planet in the solar system.

“One experiment tried to see if there were any organisms that produced gas. A radioactive broth was added to a sample of soil in a closed chamber. Any organisms present would presumably “drink” the broth and release gas containing radioactive carbon. When the broth was added to the soil, a detector did measure radioactive gas. Was there life on Mars, or had the broth caused a chemical reaction” (Aldrin and Dyson 38).

The Universe is an ever-expanding void of space littered with particulates essential to understanding life, as we know it, and as we discover it. Astrobiology is concerned with the study of life on Earth and in space, how life came to be and its evolution, and whether it can be sustained on other cosmic objects. The only way we can determine if life can be sustained on other planets is by looking at the our own: identifying sources of organic compounds, of which are vital to the evolution of life, studying the macromolecules in the origin of life, mapping the habitability of our planet it its early years, examining the evolution of life as we know it, and its corresponding environments during different stages of life, and then constructing

Most of Neptune’s upper atmosphere though includes hydrogen and helium like most other outer planets. Neptune is also akin to Uranus due to their interiors both having two layers: the core and mantle. The mantle is described as an immensely scorching thick liquid made of water, methane, and ammonia. This mantle is generally betwixt ten to fifteen times the mass of Earth. The core, on

Part of the reason astronomers are looking for exoplanets, particularly exoplanets similar to earth is to determine whether there are other planets outside of earth that can sustain life. To accomplish this goal, an exoplanet must meet a few requirements. One of this requirements is for a planet to hold life similar to that on earth, it needs to sit in the habitable zone of its host star, in what astronomers refer to as the ‘goldilocks zone’. This is the area in space in which the planet needs to orbit its host star that is not too close nor too far from its star. This will allow it to have optimal temperatures, gravitational pulls and hopefully, liquid water.
