Heraclides Ponticus and Aristarchus of Samos: “We know that the Earth is (or is not) at rest because...” The two philosophers Heraclides Ponticus and Aristarchus of Samos lived back to back as Ponticus lived from 390 BC – 310 BC and Samos lived 310 BC – 230 BC. Samos was a radical believer in the heliocentric theory of the universe, while Ponticus believed in the geocentric model; however, he believed that the Earth rotated on its axis, but it is at rest otherwise. Should these men have ever…

Stars are an appealing component of our universe. Because of our scientific advances, we know more about stars than ever before. They are born, they live, and then they die. How does this process work, though? The answer lies within thermodynamics. Thermodynamics has helped us understand how stars transfer energy and heat. Thermodynamics is a subject of physics that is concerned with heat and temperature. It is used to describe bodies of matter and their internal energy. Thermodynamics helps us…

Noah Yeasted A black hole is a large amount of matter in a small space. Black holes are one of the things that can be left over after a larger star dies. The other thing a larger star can become after it dies is a neutron star. A white dwarf is created after a smaller star dies. The only way for a star to become a black hole is if the star was 10-15 times more massive than the sun. The diameter of a black hole is approximately the diameter of New York City. A black hole’s gravitational pull is…

When a star is born it can take one of two paths. It can either take the path of a high mass star or the path of a low mass star. A high mass star will be between 10-50 solar mass and a low mass star will be between .8-10 solar masses. One solar mass is equal to M⊙ = (1.989±0.004) x 1030 kg, which is A LOT. Either path it takes, the one of a high mass or low mass star it will live about 90% of it’s lifetime in its main sequence. Once achieving nuclear fusion the star slowly contracts over…

Francois Arago’s “Report to the Chamber of Deputies” is a report presented about a proposed bill, granting M. Daguerre and to the son of M. Niepce life pension granting them a national reward due to their invention, which could not be protected by ordinary patent laws. He discusses the invention by the two men: the Daguerreotype. It is a machine that reproduces images received in the camera obscura onto copper plates. He noted that Daguerre should be well credited for the effort, time and money…

The Race Through Space The Race Through Space is the newest and spectacular roller coaster in Pennsylvania that goes at a speed of 0-50 miles per hour in three seconds. This roller coaster takes you through all eight planets going at an average speed of sixty miles per hour. Race Through Space starts by shooting you up a whopping 210-foot hill reaching the Sun at instantaneous speed before adventuring through the planets. These planets are created to appear like the actual planet.…

exoplanet is described as a planet that orbits a star outside our solar system. The majority of the exoplanets scientists have discovered were found in the past two decades, mainly with the Kepler space telescope. These planets are all different in orbit, size, and type. Some are smaller than Jupiter, or even larger than Jupiter, but essentially all of the exoplanets that we know of a larger than the Earth. Scientists have even found planets that orbit two stars, as opposed to the normal one.…

SUPERGIANT STAR Supergiants are among the most luminous and massive stars, ranging between 7-10 solar masses and can range in brightness from thirty thousand to hundreds of thousands the output of our sun. They reside in the top region of the Hertzsprung-Russel diagram; having temperatures from 3,500k to over 20,000k and having bolometric absolute magnitudes between -5 and-12. Supergiants are massive enough to begin burning helium gently in their core before it becomes degenerate, and without…

to two main factors. Fewer stars (the universe's light bulbs) are being made and our universe is expanding. “More stars are dying then being born” we know this because after looking 2 billion years into the past we have seen a brighter universe, this has many implications. Since stars are responsible for almost all the light and energy in our universe a declining of them means a declining of their produce which will darken and freeze the universe. The absence of stars is a…

I choose the phoenix because first it sounds cool and it is easy to draw. It is located on the southern sky, based on the photo it looks like it has 6 stars. The phoenix is the 37th constellation in size. The constellation was named after the mythical bird that rises from its own ashes.The mythical bird phoenix is known as the sacred fire bird across many mythologies: Greek, Persian, Arabic, Egyptian, Roman, Turkish, Indian and Chinese among others. The phoenix was said to have resembled an…
