Comet

Is it a bird? a plane? a superhero? No it’s a Comet! Comet’s are “cosmic snowballs of frozen gases, rock and dust that orbit the Sun”. Comet’s generally range from the size of 750 meters to 20 kilometers. Currently there are 3,717 comets known to man. Comet’s form from dust particles combining to form icyContinue reading “Comet” Continue reading

Comets: where do they come from?

A comet is made of a nucleus (inner core), coma (cloudy envelope around the nucleus), and then a tail. Where exactly do these beautiful, fast-moving cosmic snowballs come from? Scientists are able to trace comets that we see in the inner solar system by retracing their orbits. Through this, scientists believe that comets come fromContinue reading “Comets: where do they come from?” Continue reading

So Close, Yet From So Far ☄️

The above image is of Comet Atlas, which is a comet that has been getting closer and much, much brighter over the past few weeks. If it doesn’t fizzle out, Comet Atlas will be able to be seen by the naked eye in as little time as a couple of weeks, at places without much … Continue reading So Close, Yet From So Far ☄️ Continue reading

Comets as Omens of the Future

Comets have been noticed by ancient civilizations for millenia, and, like many other celestial bodies, were viewed as omens of the future. Comets in particular were considered bad omens. The most famous example is Halley’s Comet, seen in 1066 by the English and theorized to have been an omen for Harold II of England’s death. … Continue reading Comets as Omens of the Future Continue reading

Kuiper Belt Objects…What Are They?

Kuiper Belt Objects are unique in that they have different compositions than most asteroids and different orbits than most comets. This has led astronomers to contemplate the identity of Kuiper Belt Objects. Surprisingly, the answer isn’t so clear. Asteroids are mostly composed of rock while comets are mostly composed of rock and ice. Most Kuiper … Continue reading “Kuiper Belt Objects…What Are They?” Continue reading

Comets

Comets get the “dirty snowball” nickname from their composition: they are a little bit of rocky dust, a good amount of chunks of ice, and a pinch of more complex compounds.  Spectra analysis reveals the presence of hydrogen compounds within comets, and the existence of hydrogen compounds like water and the presence of carbon dioxide … Continue reading Comets Continue reading

The End of the World?

There are so many objects in the solar system that coexist with Earth in this universe. These objects range range from other planets, moons, asteroids and comets. But what would happen if they stopped playing nice with each other and ended up colliding? Specifically, what would happen if a comet hit the Earth? Well, that … Continue reading The End of the World? Continue reading

Dirty Snowballs

Comets are often referred to as “dirty snowballs“. That is because they are made up of a lot of many components that a dirty snowball would also consist of, and more! Many comets consist of dust, ice, carbon dioxide, ammonia, methane, and many more other components. When a comet gets close to the sun, some … Continue reading Dirty Snowballs Continue reading
