How Astronomy may harm Life on Earth

A new study by Nature Astronomy has tapped an estimate for the greenhouse gas emissions of the astronomy industry. Unfortunately, despite the fact that the global astronomy industry is much smaller than many other industries, its emissions are strikingly large. The number estimated by this study is a staggering 20 million tonnes of CO2 annually. […] Continue reading

The Future of Fusion

While stars are powered by nuclear fusion, nuclear reactors here on Earth have yet to make that leap. Fission is our only readily available source of nuclear power, but it is significantly less lucrative than its counterpart. The difference is the process, which combines two isotopes of hydrogen to trigger an energy release instead of […] Continue reading

The Martian: Based in Science or Fiction?

The Martian originated as a book written by Andy Weir, then was adapted into a movie which was directed by Ridley Scott. The book and the movie prided themselves on being scientifically accurate. In fact, when Andy Weir was first writing the book, he published chapters on his blog, and adjusted them based on the […] Continue reading

Let’s Talk About Super-Earths

Super-Earths refer to planets discovered that are more massive than earth, yet lighter than ice giants like Neptune or Uranus. These super-earths can be composed of rock, gas or both and they must be between can be between 2 and ten times the size of earth. Despite their category name, this type of planet is […] Continue reading

Blog 4: Black Holes

Black holes have always been a topic that interests me, and this article gives some very cool insight to a possible cause for the formation of these black holes. Most black holes have been found to form as the result of stars collapsing, and then when matter in multiple black holes collides, these black holes […] Continue reading

Earth’s Atmosphere and Life

Earth’s atmosphere is conducive to life in a way other terrestrial worlds’ atmospheres are not.  This is because of the greenhouse effect, which keeps Earth warm and allows water to exist in its liquid form. Other planets such as Mercury which do not have an atmosphere or the greenhouse effect are extremely hot during the […] Continue reading

Blog#4 Dark Energy and Dark Matter

Dark Energy and Dark Matter sound both exotic (and yes they absolutely are) but they have very different meanings and opposite effects: One expands our universe while one creates more gravity. High-z Supernova Search Team was founded in 1994 and in 1998 they found that one investigated supernova is fainter than Hubble’s law predicted. This […] Continue reading

Halley’s Comet

Halley’s Comet was the first comet understood to be a periodic comet, or a comet that can pass through the solar system multiple times. The English astronomer Edmund Halley (1656-1742) noticed that the previously recorded orbits of three comets were ve… Continue reading

Solar Sailing Through The Sea of Space

As an imaginative mind might ask: can we use the Sun’s light to propel a spacecraft through space? Surprisingly, this avenue of spacecraft propulsion has, and is being, explored. Figure 1 displays the Japanese IKAROS satellite that was deployed on May 21, 2010. The spacecraft was equipped with a 14 m x 14 m solar […] Continue reading

Mercury and its core | blog IV

Measuring just over one-third of Earth’s diameter, Mercury is the smallest terrestrial planet in the solar system. However, relative to other worlds, Mercury’s core constitutes a very large part of its volume. Despite the vast difference in their scale, “Mercury’s inner core is indeed solid [and] very nearly the same size as Earth’s inner core,” […] Continue reading
