What’s the Difference Between LEO, MEO and GEO Satellites?
As of the beginning of 2023, nearly 15,000 satellites are orbiting our planet. With so many orbiting bodies circling the Earth, it's a miracle they don't crash into each other, right? It might seem like magic, but in reality, it's because they aren't all orbiting at the same height. Let's take a closer look at what LEO, MEO and GEO satellites are, and why more companies are investing in LEO and MEO satellites to support space exploration.
Stargazing Calendar for July 2023
Get ready for a month filled with celestial wonders! In July, Mercury transitions in the sky, Venus and Mars dance closely, and comets reach perihelion and perigee. Don't miss the supermoon, many conjunctions, asteroid 15 Eunomia and Pluto at opposition, three meteor showers, and other breathtaking events. Grab your telescope and prepare for a dazzling show in the night sky throughout the month of July.
A Pulsar With Planets
Pulsars emit deadly radiation, disintegrating DNA and making them dangerous. Surprisingly, some have planets orbiting them, defying current theories.
What is Celestial Navigation?
We've been dreaming of the stars for longer than we can remember, staring up at the twinkling lights that fill the night sky and wondering what they are. We've even written songs about them. Centuries ago, before the advent of GPS, explorers and adventurers relied on celestial navigation to help them map a path to their destination. What is celestial navigation, how does it work and when was it relied upon?
What Experiments Did Scientists Conduct on the ISS?
ISS: A scientific marvel in space. Over 3,000 experiments conducted, from zero-gravity Parkinson's research to interstellar 3D printing. Exciting future ahead!
Why Are Satellites So Important?
SpaceX has been launching 60 satellites at a time as part of their Starlink constellation. When complete, this network will provide high-speed, low-latency internet to the entire world. This project provides one example of a type of satellite orbiting at various heights above the planet’s surface. Why are satellites so essential?
Stargazing Calendar for June 2023
Hello fellow stargazers! June offers a range of astronomical events, including Mars and M44's close approach, many conjunctions, and asteroid Parthenope at opposition. Meteor showers like the Daytime Arietids and June Bootids also grace the sky. Don't miss them!
String Theory in Simple Words
The biggest dilemma of Einstein’s life represents the search of a unified theory. Scientists all over the world are currently engrossed in the quest of a unified theory where we unify all the laws of physics, be it Quantum mechanics or the Classical physics: all the laws collated in one single framework which could predict anything and everything. Currently, we have multiple theories and suggestions for the unified theory but the very promising and compelling one is “the string theory.”
Top Mistakes Beginning Astronomers Make
Amateur astronomy is not for everybody, just like golf or football is not for everybody, but if you are sure that you want to take up the hobby of gazing at the Universe (or at least some of it) in your free time, you need to get the basics right. Getting it wrong, like so many other beginner amateurs have done, means that your expensive new equipment will almost certainly end up gathering dust in your garage - never to see starlight again.
Saturn’s Moon Mimas Looks Like Pac-Man In Infrared
In an earlier article we have showed you how Saturn's moon Mimas totally looks like the Death Star from the Star Wars movies. Now it seems that Mimas also looks like Pac-Man from the 1980s video game when seen in infrared.
Stargazing Calendar for May 2023
Hello fellow stargazers! This month the big event will be a penumbral lunar eclipse, but there are also two meteor showers, two comets at perihelion, many conjunctions, and one near-Earth object making a close approach to Earth.
How Do Spacecraft Withstand Re-Entry into Earth’s Atmosphere?
If you’re lucky when you look up in the sky at night, you might see a shooting star. As you’re making your wish, what you’re actually seeing is a small piece of rock or space junk burning up in the atmosphere. The friction of re-entry causes the shooting star to ignite and burn, which is why you see a brief flash of light.
What Are The Benefits of 3D Printing in Space?
Will 3D printers be commonplace in space? What are the benefits of 3D printing in space and will we see more of it in the future? Learn more!
How Will the Internet of Things Change Space Exploration?
The Internet of Things has the potential to change our world immensely. It will present new opportunities, as well as new challenges. IoT refers to the idea of connecting virtually any electronic device to the Internet and connecting them through the Internet to each other. Astronomers have also jumped in on the IoT conversation, and it turns out they have some issues with the up-and-coming network of connected devices.
