Discover the key evidence suggesting that Triton, Neptune's moon, is a captured moon. Explore its unusual orbit, composition, and unique features, uncovering the mystery of its origins.
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.
As a species, we're working on expanding our horizons — literally — by making our first forays into outer space. Despite this push toward space exploration, there is still a lot about the universe around us that we don't know, and a lot that we don't even know to ask about yet. On top of that, much of the data that we could be collecting from outer space is invisible to the human eye. What tools are scientists using to gather data in space?
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.
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.
Despite some delays, the highly anticipated kick-off to NASA's Artemis program finally debuted with the launch of Artemis I. This unmanned mission to orbit the Moon is the first test of the Orion spacecraft carried by a Space Launch System (SLS) rocket.
Traditionally, satellites were simply strapped to larger rockets designed to push them into higher orbits, but this can be an incredible waste of fuel and resources. However, Spaceflight Inc.’s Sherpa vehicles may help change that. So what are Sherpa vehicles, and how are they supporting satellite launches?
More than 2,000 satellites are orbiting the Earth at this very moment. They are used for communication and many other purposes. This article covers different aspects of satellite uses in navigation, with a strong emphasis on navigation. Then it looks into the Galileo Satellite Navigation System.
What are satellites used for? Our tech and communication relies mostly on these devices. Explore all uses of wireless communication and find out if too many manmade devices orbiting the Earth poses any dangers.
In the 1970s, Mariner 10 photographed less than half of Mercury's surface. MESSENGER's mission is to enter orbit around the planet, complete the detailed mapping of Mercury and return data about magnetic fields and particles in the planet's vicinity.
Space waste, space junk, orbital debris…whatever you call this orbiting mass of objects, they are a big issue. Space waste doesn't just make earth's orbital corridors look untidy, it poses a very real threat to the future of space exploration and our way of life. Read on to find out more…
The Necklace Nebula consists of a bright ring, measuring nearly 20 trillion kilometers across, with dense, bright knots of gas spread out in a way that resembles the diamonds in a necklace. The knots are not stars, they only glow due to the absorption of ultraviolet light from the two stars located in the center of the nebula.
