Hubble in his 1936 work The Realm of the Nebulae and, as such, forms part of the Hubble sequence. Spiral galaxies consist of a flat, rotating disc containing stars, gas and dust, and a central concentration of stars known as the bulge.(Sloan) Spiral galaxies resemble spiraling pinwheels, nearly 77% of space consists of spiral galaxies. Though the stars and other visible material contained in such a galaxy lie mostly on a plane, the majority of mass in spiral galaxies exists in a roughly…

Studies have shown that when two strangers are forced to talk and maintain eye contact, it can make them fall in love. This is what happened between Daniel Bae and Natasha Kingsley in the book The Sun Is Also a Star, by Nicola Yoon. Daniel is a Korean-American poet and Natasha is an undocumented immigrant who is being deported to Jamaica in twelve hours. When they first meet Daniel feels an instant connection, so he tries to convince Natasha that they are in love by following her around New…

infinite number of bright stars (Newton 1). This question fascinates me because every celestial object that can be observed with our eyes, should have an important reason and role to play. The paradox about the night sky was also argued by Kepler as stated in his “Conversations with the Starry Messenger” and suggests the night sky should light up brightly since the universe was infinite itself with stars scattered in every part of space (Newton 3). Hence, our eyes should meet a star in every…

the M31 galaxy that the IMF is actually fairly consistent. Even though the stars that were examined differed from less than a tenth the size of the sun to a hundred times as large, from four million years old to over twenty million years old, and from one side of the galaxy to the opposite side, the clusters all seemed have a uniform distribution of stars based on color and size. This is surprising, given the fact that star formation in and of itself is very complex. Having gathered this new…

the time you got anywhere near it your atoms would have been ground up and used to fuel the black hole. It is this fear of the unknown that is the scariest thing about a black hole. How could we mitigate the effects of a force of nature that eats stars? Further explanation Black holes are suns that have collapsed in on them selves because they have gained to much…

TRAPPIST-1 twice as old as our close planetary system 0 BY/ON 13 AUGUST 2017 SCIENCE Aug. 11 — Astronomers have limited in on a more exact gauge of the TRAPPIST-1 framework. Researchers trust the star and its exoplanets are in the vicinity of 5.4 and 9.8 billion years of age — as much as twice as old as our close planetary system. The sun was conceived 4.5 billion years back. In February, NASA declared the disclosure of seven Earth-sized planets circling TRAPPIST-1, a ultra-cool smaller…

(the red end of the spectrum) in radiation from distant galaxies and celestial objects. This is interpreted as a Doppler shift that is proportional to the velocity of recession and thus to distance. Stars 1. So creating a brand new element requires loading an atom's nucleus with more protons. Stars create new elements in their cores by squeezing…

that cannot be directly seen because it does not interact with light. This mysterious matter makes up the majority of mass in a galaxy. Although we cannot see dark matter we know that it is out there because we can see it effecting the motion of the stars in a galaxy and gravitational lensing. The first piece of evidence for dark matter is in the way we have observed galaxies moving. You would likely expect their behavior to replicate that of the Sun and the planets, with the velocity of…

ASTROPHYSICS Methods used to search for extrasolar planets Lucky Ruangsiri 24.02.2016 Extrasolar planets are planets that revolves another star apart from our solar system. The human race has found nearly 2000 confirmed extrasolar planets by the year 2016, and this has fuelled the search for extra-terrestrial life as we scour the universe for anything out there. How do we discover these planets that are light years away from the earth? An extrasolar planet detection technique is the…

the night and what do you see? Millions of twinkling lights, also known as stars. Stars are one of the most popular astronomical objects and represents the building blocks of galaxies. A star is defined as a vast ball of gas held together by its own gravity. The nearest star to earth is the Sun. Similar to a living organism, stars have a life cycle in which they are born, they develop and grow, and eventually die. Stars begin as a vast cloud interstellar dust (mostly carbon or silicon) and…
