Pivoting from Principle

Astronomy is awesome.  It lets us make cool observations (e.g., things that inform our understanding of the foundations of the universe, like the Cosmic Microwave Background), helps us ask big questions (e.g., why does the universe exist?), and reminds us that not all questions have answers (e.g., we can’t really expect an answer to theContinue reading “Pivoting from Principle” Continue reading

Celebrating the Vernal Equinox

Spring is a season that is characteristically associated with birth and life. It symbolizes an end to Winter and the transition to the (personally) much more favorable, Summer. While I probably enjoy Summer more than Spring overall, there is something about the feeling I get seeing all the plants grow, the leaves come back, tonsContinue reading “Celebrating the Vernal Equinox” Continue reading

The Earth, the Moon, and the Space In Between

Since space seems so far away to most of us humans, we can forget how truly massive the emptiness of space is. Space really is appropriately named, because so much of it is just that – empty space, nothing there. For example, let’s look at the distance between the Earth and the Moon. While theContinue reading “The Earth, the Moon, and the Space In Between” Continue reading

What’s up with the tropics?

Latitude and longitude coordinates are seen everywhere; they’re immensely useful for marking geographic location and helping with navigation. The system is simple enough: latitude is distance north or south from the equator and longitude is distance east or west from the Prime Meridian. But what are the Tropics of Cancer and of Capricorn that areContinue reading “What’s up with the tropics?” Continue reading

The Beginning: A Little More of Me

Welcome to the inaugural post to Jonah’s Astronomy Interests! Just to start, here are some things about me because why not: I’m from St. Louis, Missouri (if you couldn’t tell from the picture above) and I wish I could’ve minored in astronomy but physics wasn’t the move. Another thing to share: I love when I’mContinue reading “The Beginning: A Little More of Me” Continue reading

Finale – Culminate Post

I learned much more than I thought I would in this course. Before taking this class, all I really knew about our solar system was that there are 8 planets (and Earth is the third one), the asteroid belt is a thing, Jupiter is big, and Saturn is the planet with pretty rings. I didn’t … Continue reading Finale – Culminate Post Continue reading

I See the Light

An amazing part of the class this semester was the ability to understand and correct some of the misconceptions that I have held about the Solar System for years. Whether it was about the ‘dark’ side of the moon, the brightness of the North Star, tides, the asteroid belt being hard to navigate through, or … Continue reading I See the Light Continue reading

A Whole New World!

Because the caves, mines, and crevasses on Earth are filled with extremophiles, NASA uses those lifeforms as a guide to its exploration of the universe. The hidden parts of the planet have to make their own way of survival. Surface life has photosynthesis, but subsurface only a tiny fraction of that energy trickles down so … Continue reading A Whole New World! Continue reading

Eight Planets or Nine?

Most of us probably remember a time when the Solar System had nine planets, with Pluto as the ninth and (usually) farthest from the Sun. In 2006, following the discovery of Eris, the International Astronomical Union (IAU) voted to reclassify Pluto as a “dwarf planet” (don’t forget the quotation marks!). However, there might one day […] Continue reading

A Moon Above the Rest: Jupiter’s Moon Ganymede

Galileo Galilei discovered many “luminous objects” in 1610 that were orbiting Jupiter. Thought to be stars, it was discovered that they were moons: Io, Europa, Ganymede and Callisto. Ganymede is the largest moon in the Solar System and is even larger than the planet Mercury. It is the only satellite in the Solar System known to possess a … Continue reading A Moon Above the Rest: Jupiter’s Moon Ganymede Continue reading
