What are Molecules?

For millennia, scientists have pondered the mystery of life – namely, what goes into making it? According to most ancient cultures, life and all existence was made up of the basic elements of nature – i.e. Earth, Air, Wind, Water, and Fire. However, in time, many philosophers began to put forth the notion that all things were composed of tiny, indivisible things that could neither be created nor destroyed (i.e. particles). However, this was a largely philosophical notion, and it was not until the emergence of atomic theory and modern…

What is a Magnetic Field?

Everyone knows just how fun magnets can be. As a child, who among us didn’t love to see if we could make our silverware stick together? And how about those little magnetic rocks that we could arrange to form just about any shape because they stuck together? Well, magnetism is not just an endless source of fun or good for scientific experiments; it’s also one of basic physical laws upon which the universe is based. The attraction known as magnetism occurs when a magnetic field is present, which is a…

MIT Claims they are Programming Humanoid Robots to help Explore Mars. But we all Know It’s Cylons!

For over a decade, robots have been exploring Mars in advance of the crewed missions that are being planned for the coming decades. And when it comes time for astronauts to set foot on the Red Planet, they will be looking for robots to help them with some of the legwork. After all, exploring Mars is tough, laborious, and dangerous work, so some robotic assistance will probably be necessary. For this reason, back in November of 2015, NASA gave the Massachusetts Institute of Technology one of their R5 “Valkyrie” humanoid…

Looking for Canada’s Next Generation of Space Explorers

For decades, Canada has made many contributions to the field of space exploration. These include the development of sophisticated robotics, optics, participation in important research, and sending astronauts into space as part of NASA missions. And who can forget Chris Hadfield, Mr. “Space Oddity” himself? In addition to being the first Canadian to command the ISS, he is also known worldwide as the man who made space exploration fun and accessible through social media. And in recent statement, the Canadian Space Agency (CSA) has announced that it is looking…

Uh, We’re Going To Need A Bigger Landing Pad

Since 2000, Elon Musk been moving forward with his vision of a fleet of reusable rockets, ones that will restore domestic launch capability to the US and drastically reduce the cost of space launches. The largest rocket in this fleet is the Falcon Heavy, a variant of the Falcon 9 that uses the same rocket core, with two additional boosters that derived from the Falcon 9 first stage. When it lifts off later this year, it will be the most operational powerful rocket in the world. …

Now, Witness The Power Of This Fully Operational Radio Telescope!

Relax, its not a space station! And according to the Chinese government, it’s for entirely peaceful purposes. It’s known as the Five-hundred-meter Aperture Spherical Telescope (FAST), a massive array that just finished construction in the southerwestern province of Guizhou, China. Equivalent in size to over 20 football fields joined end to end, it is the world’s largest radio telescope – thus ending the Arecibo Observatory’s 53 year reign. As part of China’s growing commitment to space exploration, the FAST telescope will spend the coming decades exploring space and assisting…

Good News, Martian Colonists Can Eat All the Radishes They Want

When your stated purpose is to send settlers to Mars by 2026, you’re sure to encounter a lot of skepticism. And that is exactly what Dutch entrepreneur Bas Lansdorp has been dealing with ever since he first went public with MarsOne in 2012. In fact, in the past four years, everything from the project’s schedule, technical and financial feasibility, and ethics have been criticized by scientists, engineers and people in the aerospace industry. However, Lansdorp and his organization have persevered, stating that they intend to overcome all the challenges…

A Star Is About To Go 2.5% The Speed Of Light Past A Black Hole

Since it was first discovered in 1974, astronomers have been dying to get a better look at the Supermassive Black Hole (SBH) at the center of our galaxy. Known as Sagittarius A*, scientists have only been able to gauge the position and mass of this SBH by measuring the effect it has on the stars that orbit it. But so far, more detailed observations have eluded them, thanks in part to all the gas and dust that obscures it. Luckily, the European Southern Observatory (ESO) recently began work with…

What are the Different Masses of the Planets?

It is a well known fact that the planets of the Solar System vary considerably in terms of size. For instance, the planets of the inner Solar System are smaller and denser than the gas/ice giants of the outer Solar System. And in some cases, planets can actually be smaller than the largest moons. But a planet’s size is not necessarily proportional to its mass. In the end, how massive a planet is has more to do with its composition and density. So while a planet like Mercury may…
