Today is February 29. Unlike every other day in the year, this day only shows up in the calendar once every four years… but why? To understand this, we’re going to use a little bit of history and astronomy to get to the calendar that most of the world uses today. First, let’s talk about… Read more »
It’s easy to think of the sun as a simple bright sphere in the sky, constant and unchanging; but, that is far from reality. The sun is dynamic, with many solar flares, cells of convection, and even storms. One of the easiest changes to see are sunspots, which are located on the surface of the… Read more »
Looking back into the archives of scientific papers published in the past few decades, the majority have one, or at most four, authors. Most projects were conducted by a single individual (or a man and multiple uncredited women, but that’s a whole different topic than what I’d like to discuss here): one person started with… Read more »
Our blog would be nothing without our writers. Unfortunately they can’t stay here forever; they must go on to their next great adventures in life. So we wanted to take a moment to recognize a few of our authors who have recently left or are preparing to leave soon. We wish you all the very… Read more »
The anniversary of the first steps on the moon is today and undoubtedly you’ve seen a lot of images from the landing. News media love to show the footprints, the saluting of the flag, and the Earth-rise over the lunar surface. However there are many pictures that get overlooked. So here we present 5 photos (and… Read more »
Water is essential to life on Earth. So, if we are searching for life off-world, it would make sense to look for signs of water. Astronomers have been doing exactly that: employing different methods to find the first signs of life outside of our own world. Until recently, it wasn’t known whether there is water… Read more »
Sue the T Rex. Lucy the early human ancestor. These are scientific discoveries that are remembered and even loved. They have names and feel real despite being collections of bones. Even the buckyball evokes the idea of fun where other structures of molecules do not. Names are important. Astronomy has been doing this for a… Read more »
Planets are formed in “protoplanetary disks” composed of gas and dust orbiting a central star. Once a planet has formed in the disk, the radius of its orbit can change due to gravitational forces between the planet and material in the disk. In this way, planets can migrate from their original location, a phenomenon that… Read more »
Taking astronomical images can be a very rewarding process—in part because of the gorgeous images you take, but also in part because of all the obstacles that can prevent you from observing the skies. We can protect our telescopes in buildings during the day to keep them clean and dry, but when night comes and… Read more »
This post is from ScIU’s archives. It was originally published by Maria Tiongco in September 2016, and has been lightly edited to reflect current events. Have you ever taken time to gaze at the stars on a clear night, either with a casual eye or a telescope? If so, you might have seen the famous… Read more »
