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?
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!
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 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.
What Is a Hybrid Solar Eclipse and How to Observe It Tomorrow April 20, 2023
A hybrid solar eclipse is a rare type of solar eclipse that combines features of both total and annular eclipses. A hybrid eclipse, also known as an annular-total eclipse, happens when the Moon's distance from Earth and position in orbit are just right to provide a spectacular celestial show.
How Beginners Can Safely Observe Solar Prominences, Filaments & Flares
Use solar filters for safe Sun observation. Smartphones can enhance views when attached to telescopes, but protect your eyes and adjust camera settings.
Stargazing Calendar for April 2023
Hello fellow stargazers! This month the big event will be a rare hybrid solar eclipse, but unfortunately it will be visible to only a few small areas of the world. For the rest of us, we have two large objects at opposition: dwarf planet Haumea as well as large asteroid Iris. There will also be two meteor showers as well as many conjunctions.
A Good Time to Observe Dwarf Planet Makemake
On March 29, we have a great opportunity to observe the dwarf planet Makemake. It will be at opposition, which means it will reach the highest point in the sky at around midnight and be opposite to the Sun. At around the same time Makemake will also reach its closest point to the Earth (perigee) at a distance of 51.77 AU. Its peak brightness will be an apparent magnitude of 17.1, which makes it the brightest trans-Neptunian object after Pluto.
A Good Time to Observe Dwarf Planet Ceres
On March 21, we have a great opportunity to observe the dwarf planet Ceres. It will be at opposition, which means it will reach the highest point in the sky at around midnight and opposite to the Sun. At the same time Ceres will be closest to the Earth (perigee) at a distance of 1.59 AU. At this time it will be the brightest, with an apparent magnitude of 6.9. Look in the constellation of Coma Berenices with binoculars or a telescope.
