Pale Blue Dot
Over the course of the semester, I learned a lot of things. I started off learning about the size and scale of the universe, and the enormous distances between planets and stars. We can’t even travel a tenth of a light year in our lifetime in the fastest spaceship we own. Our furthest spacecraft, Voyager … Continue reading Pale Blue Dot → Continue reading
Tardigrades
Tardigrades, also known as water bears, are known to be one of the strongest creatures on earth. They are an extremophile and can survive in almost any environment or climate. They’ve been found “from mountain tops to the deep sea and mud volcanoes; from tropical rain forests to the Antarctic. These micro-animals grow to a max length of about 0.5mm. … Continue reading Tardigrades → Continue reading
The Olber Paradox
My appreciation for astronomy and astrological theorization and examination has increased significantly throughout this course. From the periphery, astronomy seems overwhelmingly complex and unimaginable. But, when you venture into the weeds and examine closely, it is remarkably intuitive and fundamental. Still, certain phenomena have yielded contradictory conclusions that befuddle some of the brightest of minds. … Continue reading The Olber Paradox → Continue reading

Extremophiles
Incredibly species of microorganism and microbes have tested the limits of evolutionary theory as they have been discovered to survive an incredible range of extreme conditions. These microbes, called extremophiles can survive in various extremes: incredibly high temperatures, near-vacuum condition of space, and in the freezing cold. In fact, scientists have discovered microbes within the … Continue reading Extremophiles → Continue reading

On This Day in Astronomy History…
On April 27th, 1961, fifty-seven years ago, NASA launched Explorer 11 into space. This satellite held the first gamma-ray telescope to go into space. Gamma rays are the wavelength of light with the highest energy levels. These wavelengths can originate from sources such as supernova explosions, supermassive blackholes, and solar flares. While scientists had […] Continue reading

Are Viruses the Missing Piece in Astrobiology?
Despite being the most abundant form of life on Earth, viruses and their dormant state known as virions, are often left out the conversation in identifying life outside this place. However, a group of scientists are now calling for this to change. Noting that the term virus is only used six times within NASA’s 250-paged […] Continue reading

Blog 7: Extremophiles of Yellowstone
I will soon be embarking on a family trip to Yellowstone, my first visit to this National Park. Yellowstone is geological hotspot and is home to a plethora of thermal features, including hot springs, geysers, and the massive volcano itself. The hot waters may seem incapable of housing life, but they are home to an … Continue reading Blog 7: Extremophiles of Yellowstone Continue reading

Primordial Stars and Dark Matter
A little over a month ago, astronomers in Western Australia detected the signals of stars that formed within the earliest epoch of the Universe. This discovery marks the detection of the oldest signals ever to be received, and with it, evidence for the presence of dark matter at a time when the lights of the … Continue reading Primordial Stars and Dark Matter → Continue reading
