Who Discovered the Solar System?
We know that many philosophers and scientists discovered various things in the universe. From the ancient times people had a curiosity to find new things. So they invented different things to observe the night sky. Gallileo invented the telescope and through it man had the chance to find and explore new things. Our solar system is also like a theory.Which we say began with the big bang. Actually the discover of the solar system was mainly started by the ancient civilizations.
How did Galileo discover that the solar system has the Sun in the center with just his telescope?
Galileo neither discovered or proved the heliocentric theory.He did show that earth was not the only object that had other object(s) revolving about it when he discovered the moon's of Jupiter. Copernicus gave credence to a heliocentric system, but it was Kepler's laws along with Newton's ability to derive the laws from fundamental principles that really did the trick.Kepler used the measurements of planetary motion made by Tycho Brahe in formulating his laws, and these were all naked eye measurements.So, the telescope was completely unnecessary for the developement of the Heliocentric theory.
Who discovered the solar system?
The solar system was not “discovered” by one person. Rather it was a process that spanned tens of thousands of years, with many thousands of people contributing to our current understanding.Like most macroscopic natural phenomena, it was first observed deep in pre-historic times, then curious minds tried to make sense of those observations, then more and better observations were made, and better theories were create to explain all the observations, and so on. This cycle, in essence, is still happening today.Modern observations are made with space probes and orbiting telescopes, which are used to refine our theories of planetary formation, and long-term dynamics and evolution. Though today astronomy is entirely based on science, there is a direct thread this reaches, all the way to the ancient stargazers who looked up at the stars and imagined them as the homes of gods and heroes. The ancient Greeks noticed that a few of the stars seemed to wander between the majority of “fixed stars”, so they imagined them being divine emissaries and so named them πλανῆται (planētai), meaning "wanderers".
Pretend you discover another planet in our solar system, and that this planet orbits the sun in a circular orb?
if i discovered another planet in our solar system that would mean that it has been around for billions of years, so its likelihood of colliding with earth would be practically nil, so A is out. you cannot tell the mass of a planet based on its orbital radius, you would need to know how fast it is moving as well, so B is out C well unless the planet has the same mass as the earth it's orbital period could be different, so technically c is out. D finally is true in theory assuming that the atmospheric composition is the same as earth's its surface temperature would also likely be very similar. however since we are not told about its atmosphere it could have a very different temperature. so far this one is the best though. E based on orbital radius alone there is no evidence for life E is out. so yeah D seems to be the most likely one but it still has flaws to. any of them would require more information, we could make guesses about orbital period and planetary mass, but not enough information is given to make a true choice. sort of a bad question really.
How much do we have left to discover?
Nobody knows. One of the fun things about science is that, when you learn a new thing, this new knowledge creates more questions.For instance, the astronomers who are running the New Horizons program had “known” what Pluto “had” to look like before the probe arrived. When the first pictures came in, they were blown away, because Pluto was (other than being round) almost completely unexpected. They’ll be puzzling over that data for years to come!And, not too long ago, we’d assumed that we “knew” how solar systems formed, because we’d studied the one in which we live in such detail. But now with the Kepler telescope, etc, we’re discovering that we have almost no clue how Earth got here, why Jupiter is where it is, or what a “normal” solar system is like.
Who first discovered that sun is the center of solar system?
Pythagoreans had entertained in secret the idea that there was some kind of central fire the Earth, Sun and planets were going around, as publicly espoused later on by one of them, Philolaus of Croton (470–385 BCE).But it was Aristarchus of Samos (310–230 BCE), the same generation as Archimedes, the first one recorded in history who had the clearest insight, that basically stands up until today, to specify that the Sun was the big star in the center of the same system with the planets, which go around it and receive its light, the Earth also being a planet like the other 5 seen with the naked eye (Hermes, Aphrodite, Ares, Zeus, Kronos), with the Moon going around Earth, and the rest stars being other suns very far away to infinity, very big and with their own light.AristarchusHe made do with instruments of the time and also calculated the distances of the Earth from the Moon and the Sun, invented an advanced hemispherical sundial that was used as basis for scaphe sundials in all Greco-Roman world.He also noted in his time that “color is how the light falls (reflects) over various bodies” as “in absolute darkness the bodies have no color”.Renown Roman architect, military engineer and polymath Vitruvius, also recognized Aristarchus as having ‘deep knowledge of all branches of science’ (probably had access to his full works at the time).But as the world is too fond of its creation stories and social clubs, things got a bit lax on the science front, fires of ignorance consumed knowledge and people, and many centuries passed until Nicolaus Copernicus mentioned him in his 16th century manuscript espousing the heliocentric system, but for reasons unknown left him out of the references in the pressed edition of his work.
What is left for us to discover?
Science.From the beginning of time, humans have always thrived on exploration and fulfilling their desires for answers. In science currently, we accept the periodic table, the layout of a molecule, and DNA.If you think about it, all of those discoveries are very recent. New elements are being discovered. Better technology is being developed to study particles so small we cannot even begin to imagine how small these molecules are. DNA was discovered by Watson and Crick. We have “built” on our knowledge of the building block to life by discovering what DNA is made with, protein synthesis, and much more.In recent history research is being done on 3D printers, new vaccines, and how to allow humans to live longer.Scientists could discover billions of new elements of science with new and improved instruments. These instruments could reach as far as discovering an inhabitable planet Earth or as small as using a heart printed by a 3D printer in heart surgery. The possibilities are limitless.Who knows, maybe Planet X will be inhabited. Only time will tell.
Should we be surprised to discover the following solar system?
It has several planets similar in composition to the Jupiter and Saturn but similar in mass to the terrestrial planets of our solar system. Explain why or why not.
In solar energy, what is still left to invent or discover?
The ultimate solar system has still not been invented. Here are a couple of candidates:1) High-efficiency cells with low energy manufacturing - most likely to be Perovskites instead of silicon. 27% cells that are made without heat, that can also be integrated in just about any surface. 2) Hybrid - right now, it is a choice of either electric or thermal. By employing both, the efficiencies would greatly improve. And when you are dealing with heat, you want as high temperature as possible to get the highest efficiency, so concentration is required. This concept is also sometimes referred to as CHP - Combined Heat and Power. 3) A hybrid medium-temperature system: Solar cells that can withstand high temperatures (400C) from concentration, combined with heat collection, thermal storage and a turbine that runs on expanded heat (Sterling or Ericsson cycle) without any water use. That should give potential for about 70% efficiency and a combination of base load and peaking in the same system.4) High temperature CSP system: Using mirrors to achieve temperatures approaching 1000C. Operating at high temperatures are important for several reasons - first, the thermal storage can be smaller, the turbine runs more efficiently and to supply high temperatures heat to industrial processes such as ceramics, metals, glass and cement. 5) Another very interesting area for future solar energy is thermochemical storage, which does not store the heat directly, but rather fuels a reversible chemical reaction that releases high temperature heat when desired. Such thermochemical materials can be stored at normal temperatures without insulation.
