Proxima Centauri: Red Dwarf Star

The possibility of life beyond Earth is a tantalizing idea long prompting our species to wonder if there are other worlds where life exists. As space technology advances, the chances of finding life on other planets are now greater than ever. With new technologies such as satellites and solar panels, scientists are able to expand their exploration farther into our solar system. In 1995, an astronomer named Michel Mayor together with Didier Queloz discovered 51 Pegasi b. This was truly an incredible discovery that rocked the science community. Pledges b, a wobbling star the size of our sun, was slowly approaching, and according to Mayor’s

Both high- and low-mass stars respond to the depletion of hydrogen fuel in a similar manner. In order to supply the heat to oppose its own self-gravity, the star 's core again responds by shrinking. In a sort of reflex reaction, the outer regions of the star expand, causing a great increase of its radiating surface area. Although the total energy output of the star increases during this phase, the greatly enhanced surface area results in a cooling of the surface and the star takes on a redder appearance. The size and color change lead to the name of red giant for these stars. If the star is very massive, it may become what is called a red supergiant.

As a tactical response to the regional deficit of primary care providers and a marked stressing of local emergency departments along with urgent care facility resource overburden, Alpha Centauri has been developed from the ground-up as a premier walk-in healthcare entity in Elk County, Pennsylvania. We endeavor to provide quality healthcare in the vein of three key specializations necessary in our region: orthopedics, gastroenterology, and pediatrics. These specialties are often the most sought out after residential patients are referred from local urgent care and emergency departments, and our primary goal is to deliver these vital services to our patients without delay, and prioritize the care needed without the potential of degenerating conditions caused by the inability of local health systems to deliver this care in a timely manner. The initial vision and groundwork is what will become three separate walk-in clinics based on our current specialization capacities, the first and primary of which will be made ready for clientele on February 15th, 2017.

Humans have been searching for a habitable extraterrestrial planet before Galileo even assembled the first telescope. Since then, we have identified 1030 extraterrestrial planets, but only an esteemed handful of these copious supply of planets would even permit the hardiest of bacteria and single-celled organisms, let alone intelligent life. Kepler-452b is one of the most speculated planets yet discovered because it orbits within the Goldilocks Zone, or the perfect distance from its star so that surface temperatures of the planet remain stable for liquid water, and thus for life. Given that it is 60% larger than earth, takes 385 days to orbit its star, Kelper-452b exhibits almost every desirable characteristic of a habitable planet. However, it is a jaw-dropping 6 billion years old, or 1.5 billion older that our own sun.

The star Proxima Centauri is interesting because besides form the sun it is the closest star to earth, measuring to be about 4.3 light-years away. It also has an exoplanet named Proxima b that obits around it. Scientist studied how the flares emitted by the star would affect the orbiting exoplanet. It’s assumed that Proxima b would have been blasted with radiation during the flares over billions of years since the exoplanet was formed. Flares like this could have evaporated any oceans or atmospheres, and

Scientists found a new plant that has this star that’s so hot that they disbelieve there could be any molecules living on this planet named “Kelt-9b”. The founders go to the Ohio State University in Columbus, Ohio the team tells us how this planet is three times bigger than Jupiter, and the star that lives as its next door neighbor is nearly twice as hot as our own sun. The planet moves around the sun like star every one and a half earth days one side of the planet is locked into a face to face with the star which makes the face of Kelt-9b be around 7,820 degrees Fahrenheit. For a long time scientists have been focused on finding small planets by cool stars because technology today it’s easier to study atmospheres of planets potentially find

Scientists have discovered a new planet that they believe may be capable of housing life. LHS 1140 b, the planet in question, is six times heavier than Earth, yet only 1.5 times as large, suggesting that it is an extremely dense ball of metal and rock. LHS 1140 b is ten times closer to its sun than Earth, as well, making the orbit only 25 days. The sun LHS 1140 b orbits, LHS 1140, is an old, dim red dwarf star, 40 light-years from Earth in the constellation Cetus. Everything about it is rather ordinary; red dwarfs are the most common type of star, and the light that LHS 1140 produces is too dim to be spotted with the naked eye.

In about 5 billion years, the Sun will become a red giant. A red giant is a star which has completely

Outer space is a realm of new discoveries and possibilities. There is one particular planet in our solar system that is brimming with these possibilities. However, for nine years it has not actually been considered a planet. The “dwarf planet”, Pluto, has been overlooked and misrepresented in astronomy and planetary science. Since being demoted from planet status to dwarf planet status, little Pluto has raised some big questions about what defines a planet and what does not. In this paper, I will attempt to persuade you that Pluto should be promoted back to its original planet status. First, I will give you a brief history of Pluto, from its discovery to what prompted its reclassification. Next, I will explain the definition of a planet as given by the International Astronomical Union (IAU) and the definition’s flaws. Finally, I will discuss the recent discoveries of the New Horizons mission and how these new discoveries should lead to the reclassification of Pluto to its original planet status.

Today Pluto is now known as an icy gaseous white dwarf planet and is the second largest white dwarf planet with Eris being the largest. My submission will support my argument that Pluto should not be classified as a Planet or a Small Solar System Body, but a Dwarf Planet as classified in 2006, by the International Astronomical Union. First, the physical characteristics of Pluto support that Pluto has been properly reclassified as a dwarf planet. Pluto's density and size are much smaller than all other planets, as studies have confirmed that Pluto's width is 1582 miles long and the length is 1400 miles long and its mass is less than 0.024% of the planet earth.

A red dwarf star is considered to be a great spot for life because of its potential for long term habitability. For earth, the habitable zone it resides in lasts only about 7 to 10 billion years. Compare that to a red dwarf, where a habitable zone can last for for a span almost five times greater than that for earth. Thus making a red dwarf a good candidate for life to grow, develop and become advanced. Another point to consider is that many planets orbiting M dwarf, red dwarf stars are highly likely to have large amounts of water which suggests the idea that there could be many habitable planets surrounding a red dwarf star. However, red dwarf stars have a few big problems. Due to the low luminosity of a red dwarf, planets have to be relatively close for it to be in the known habitable zone. And by being so close, planets face hostile conditions. One condition is the barrage of stellar wind, which could strip a planets atmosphere. Another is that the planet could be tidally locked, so only one side would face the star. Lastly, is that red dwarf stars are emit extreme EUV and X ray

Was Mars once a lush forested marshland? Scientists may have finally found evidence of such a theory. This discovery could also place a timeline to aliens on the Red Planet as well. Leaving SpaceX to make contact in 2020. Currently, Mars is a pretty cold and inhospitable place. It looks like Arizona high desert without plant life or other organisms. Researchers have confirmed that Mars sits in the planetary “Habitable Zone.” The Red Planet is on the edge, but it shares this zone for potential life with Earth. Unfortunately, Mars is presently a frozen wasteland. However, Science is amazing and they may have dug up some new dirt about Mars’ past.

The sun is the glue that holds this galaxy together, and makes a stabilized environment on Earth to survive, and plays a substantial role for everything that happens to the earth. The sun is the largest amount of matter in our galaxy, therefore also having the most amount of mass also giving it the strongest gravitational pull. Since it has the strongest gravitational pull in the galaxy, the sun is the center of our galaxy having all the planets and asteroids surrounding it. Now this doesn't mean the sun is the biggest star there is possible, in fact the sun is just an average star. The average stars are dwarf stars, and the sun is a yellow dwarf star. Now we have dwarf planets like Pluto, compare Pluto to the Earth, now compare the Earth to the sun. That just leaves the question how big is a star? The sun only looks bigger to us than most stars because we are the 3rd planet

DX Cancri is a pretty small star. Its spectral type is M and it is made up of helium and methylidyne. Its temperature is about 3000 kelvin. The color is red and it is a main sequence dwarf star. The luminosity is 10-4 and the mass is 0.1 and the sun’s mass is 1. The radius is 10-3 and after the cycle of a dwarf star, it cools down and turns into a black dwarf star. Even though it is a lot smaller than the sun, it is still many times larger than Jupiter, the largest planet in our solar system!

Main sequence stars like our own sun enduring in a state of nuclear fusion during which they will produce energy for billions of years by replacing hydrogen to helium. Stars change over billions of years. When their main sequence phase ends they pass through other states of existence according to their size and other characteristics. The larger a star's mass, the shorter its lifespan is. As stars move toward the end of their lives, much of their hydrogen will be converted to helium. Helium sinks to the star's core and raises the star's temperature—causing its outer shell to expand. These large, puffy stars are known as Red Giants. The red giant phase is actually a prelude to a star shedding its outer layers and becoming a small, dense body called a White Dwarf. White dwarfs cool down for billions and billions of years, until they finally go dark and produce no energy at all. Once this happens, scientists have yet to observe, such stars become known as Black Dwarfs. A few stars avoid this evolutionary path and instead go out with a bang, exploding as Supernovae. These violent explosions leave behind a small core that will then turn into something called a Neutron Star or even, if the remainder is large enough, it is then turned into something called a Black Hole.
