Recommended: Tabby's Star scientific discovery
Many people wonder what and who else is out there in space. It’s a question many people ask, but few answer. It is something humans have devoted their lives to. KIC 8462852(Tabby's Star) is one of the most mysterious stars in the universe, one that has the scientific community confused about its behavior.
KIC 8462852 was first sighted using Kepler in 2011 by Tabetha Boyajian and a team of citizen scientists working on the Planet Hunters project. Then they spotted something odd. At first they didn’t know what to do, the data looked unbelievable, so they took the data to the scientists. The data was good. The star had seen dips in light by up to twenty-two percent. The largest planet in our solar system causes a drop in light of one percent. What ever

This would have to take millions of huge comets to cause a drop in light by that much which is astounding!
There are hypotheses that are on the right track but still far from a full explanation. One such hypothesis is the star still has the debris from when it was formed. But that doesn't add up. The dust and debris clears away after time and Tabby’s Star doesn’t have any evidence of being young. Also, if there was a cloud of dust it would show up on the images they observe the star with. The black hole theory is very much out of the picture as a black hole would actually brighten the light coming from Tabby's Star
Additionally, there is the alien hypothesis. It states that a super intelligent technologically advanced civilization built a object known as a Dyson Sphere which is used to drain energy from the star it is built around to power this civilization's energy needs which would actually explain both the faster dimming over time and the blocking of light by a massive object. However a Dyson Sphere would be unlikely because of no solid evidence of alien life yet, although it is odd that SETI would pay such close

...f gas, which collapsed and broke up into individual stars. The stars are packed together most tightly in the center, or nucleus. Scientists believe it is possible that at the very center there was too much matter to form an ordinary star, or that the stars which did form were so close to each other that they coalesced to form a black hole. It is argued that really massive black holes, equivalent to a hundred million stars like the Sun, could exist at the center of some galaxies
Seeing the double brown dwarfs near a star is very rare. Seeing a double near a K- type is a first to the scientific world. This star is called BD +20 2457 and it is nearing the end of its life. Normally a brown dwarf would be created either from a star formation or a planet formation. Planets form when the star revolves and pulls in dust and gas from the nebula. As th...
One effect of the expansion of the universe is the redshift ("redshift") of all wavelengths. That means, among other things, that there is a loss of energy with distance; that is, that there is an "extra" loss of brightness proportional to 1 / r. The more distant, less bright than it was even in a static universe
It’s a white giant and has a temperature of 7700 Kelvin. It’s a type A star that is 8.5 times brighter than the sun. It is most likely to be in the last stage of ordinary star-type life. Scientists are saying the sun’s older twin is found in the middle of Capricorn. Studying this star will help them see how the Earth’s sun will develop.
More than 50 years after the publication of Astronomiae Pars Optica, another man was carrying on Kepler’s work in the field of optics....

The Romantic period was an expressive and intellectual movement that originated in Europe towards the end of the 18th century and peaked in the 1800s-1850s. This movement was defined and given depth by an expulsion of all ideals set by the society of the particular time, in the sense that the Romantics sought something deeper, something greater than the simplistic and structured world that they lived in. They drew their inspiration from that around them. Their surroundings, especially nature and the very fabric of their minds, their imagination. This expulsion of the complexity of the simple human life their world had organised and maintained resulted in a unique revolution in history. Eradication of materialism, organisation and society and
It was the year 2045, and a coalition of NASA, the ESA, JAXA (Japanese space agency), and ISRO (Indian Space Agency) combined their collective resources, brain power, and monetary funds to organize one of the most ambitious missions in human history: to send an interstellar probe to the Alpha Centauri system. The name the probe was given was Stella Nauta, meaning Star Sailor. The purpose of the Stella Nauta was to look for any undiscovered properties of the stars in the system, to discover any planets, moons, or asteroids orbiting in the triple star system and to determine whether any of the planets it may or may not discover harbor life and whether it could be a potentially habitable planet for humans in the future. Before we discuss what
Human fascination with the stars is as ancient as Babylonians and has been suggested to be older than Stonehenge. From “be fruitful and multiply” to “live long and prosper,” the instinct to protect and propagate the species has manifested in religion, art, and the imaginations of countless individuals. As human understanding of space treks out of the fantastical and into the scientific, the realities of traveling through and living in space are becoming clearer. Exploring, investigating, and living in space pose an expansive series of problems. However, the solutions to the problems faced by mankind's desire to reach beyond the horizon, through the night sky, and into the stars are solutions that will help in all areas of life on Earth.
The education system in India is based on forced learning that kills student’s spirit and zest of learning. In the film “Like Stars on Earth,” we look specifically at the draw backed role played by parents and teacher in Indian education system. We follow the story of a dyslexic Indian boy, Ishaan, who always had trouble coping with his studies, but in the end with the help of an understanding teacher he is able to study normally and catch up with his peers. We will analyze this film using the concepts from Practices of Looking to explain our thesis. Eddie will cover the concepts of encoding and the ideology surrounding Indian education; Kiranjot Singh will explain the concepts of punctum, negotiated reading and producer’s intended meaning;
Light pollution is when sky glow produced by the scattering of artificial light caused by the poor quality of outdoor lighting (Nakata) causing too much wasted light dispersed upwards. Therefore recent studies show that “Nationally, more than 30% of the electricity generated for outdoor illumination is simply squandered by being misdirected into the sky. That comes to 4.5 billion dollars annually” (Lipsitz) for the electricity generated to send light into the sky and across property lines where it serves no benefit. Wasted light sent to the sky needlessly and seriously affects scientific research today for professional and amateur astronomers along with some NASA research. Astronauts have complained about this problem for years. Astronomical observatories are closing down because they can no longer see enough celestial objects to justify continuing their funding or research. For example, the Hubble telescope’s research is interrupted by light pollution, it was affected so much that astronomers did not get to see certa...
The first explanation does not make sense. The dust in a black body will heat up; this essentially acts like a radiation shield, exponentially damping the distant starlight. In addition, one cannot put enough dust into the universe to get rid of all the starlight, without obscuring your own sun.
