Spectroscopy

Spectroscopy is known as the astronomers most powerful tool. Reason being is because we can learn the information about temper-ature, motion, compositions, and other characteristics of celestial objects. Spectroscopy is also the study of interaction between matt-er and electromagnetic radiation. Which tells us about the wavelengths or frequency of the radiation. Now spectroscopy is defined as any measurement of a quantity as a function of wavelength or frequency in todays world.

#2 Topic: Telescopes

When I think of the word telescopes I picture small telescopes just to see some stars or planets. The telescope was invented in 1608 and has come a long way from today’s modern telescopes. Now astronomers use telescopes that are worth a couple hundred million or even billions. Astronomers keep building bigger and more expensive telescopes to see the light better for stars, and planets. Astro-nomers use telescopes to collect faint light and collect visible radiation.

One of the deadliest planet in the universe-HD 189733b

HD 189733b is a planet outside of the solar system and is 64.5 light years away and it is confirmed as detected in 1992 approximatly. This planet is discovered to rotate around its own start HD189733 and very closely orbits around its start. This planet is discovered to be around the same size as Jupiter and looks like our Earth like with blue spills and all but it is not at all like Earth, it is blue not beca-use of the oceans or sea but because of it’s richest clouds with silicate particles.

This planet is called deadly for couple reason, first one would be because of its speed and wind. This planet’s speed is 8,700kilometer-per-hour (5,400 mph) so the winds are horrible, the speed is seven times more speed of sounds which is super fast(just for compari-son, Hurricane Katrina’s wind speed 127mph approximately 250km per hour).

And there is Rain, since this planet has richest clouds and they cause molten glass of rain fall from the skies. Since this planet is sup-er speedy and windy the rain doesn’t fall straight but sideways, if someone lived there the rain forms as glass it might cut through a body.

This planet orbits very close to its star so it has highest temperatures, it is insanely hot. To put in a better way how close this planet is to its star, this planet revolve around its start in just about 2.2 Earth days and a day on this plant is also 2.2 Earth days so it revolves around it self also in 2.2 Earth days. This means the time it takes to revolve around it self is the same time it takes to rotate on it’s axis which is pretty interesting and super fast and it is tidally-locked planet so one side of planet is always faces its star and no stop day ti-me were as other side is always nighttime. Based on these reasons it is impossible to has any living creature to stay there.

#4 Topic: More eco-friendly rocket launches?

Hi classmates! None of us are a stranger to the issue of pollution and climate change damaging Earth, and most of it is a result of us (humans) and our footprint. This inspired a UK space startup to ask and hopefully answer the question “Can biofuel make spaceflight greener?”

Rocket launches contribute to climate change by injecting huge amounts of soot into higher layers of Earth’s atmosphere. The startup Orbex is attempting to use biopropane, a natural gas made as a byproduct during biodiesel production. One of their studies released by experts states that their bio-propane-powered rocket called Prime will produce 86% fewer emissions than a similar-sized fossil fuel launcher. There are still emissions due to the negative carbon footprint of biofuel production. The fuel is made from a mixture of waste residues and sustainably sourced materials.

However, some question if it’s even worth it, is this a waste of time? Since the space industry burns only about 1% of the fossil fuel consumed by aviation, many experts are not concerned. with the carbon dioxide emissions of spaceflight. What do you guys think, is it worthwhile?
