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 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 Continue reading

James Webb Space Telescope

In 1995, one of the most famous photos in astronomy was taken by the Hubble Space Telescope. Dr. Robert Williams instructed his team to point the lens at nothing in particular in the sky – only 0.9 arc seconds of the night sky. Over 10 consecutive days, Hubble took over 342 exposures and combined them … Continue reading James Webb Space Telescope Continue reading Continue reading

Voyager 1

Voyager 1 is currently the farthest spacecraft we have ever sent out. It was launched in 1977 and is currently 141 AU or 13 billion miles away from Earth right now. It is traveling at 38,000 mph but has not even travel a full light day yet. The original purpose of the Voyager missions was … Continue reading Voyager 1 Continue reading Continue reading

Absolute Hot

We all have heard about absolute zero – the coldest temperature possible. At this point, atoms cease to move completely. All heat is really is just the movement of atoms and the energy with which they’re moving. Hotter things tend to have more energy, and their atoms move more. Thermodynamically, it is impossible to reach … Continue reading Absolute Hot Continue reading Continue reading

Telescopes of All Kinds

Telescopes allow us to view the stars, planets, galaxies, and even quasars in great detail. Before the telescope, astronomers relied on naked eye astronomy, something Tycho Brahe was very good at. It’s really fascinating to learn how these telescopes work. Essentially, there are two types of telescopes – refracting and reflecting. Refracting telescopes use two … Continue reading Telescopes of All Kinds Continue reading Continue reading

Historical Astronomers in Context

Isaac Newton was born on January 4, 1643 and died on March 31, 1727. Isaac Newton is best known for his work on gravity. More specifically, he founded Newton’s Law of Gravitation. This formula states that the force of gravity between two objects is dependent on the massiveness of the two objects and the distance between … Continue reading Historical Astronomers in Context Continue reading Continue reading
