This Thursday (18th Feb), if everything goes smoothly, NASA’s Perseverance Rover will touch down on the surface of Mars. The landing sequence required to get it safely to the surface is like something from science fiction. It is a complex landing sequence, made all the more difficult by the fact that real time communication withContinue reading “Perseverance’s 7 Minutes of Terror”

Distances in Space
Space is big, really big, way bigger than any of us can really comprehend. On Earth, we use measurements such as metres and kilometres. These will be sufficient for some features on the planets and moon or moons like craters and mountains. Consider the distance from the Sun to Neptune which is about 4,498,396,441 km.Continue reading “Distances in Space”
Could There Be Life On Venus?
Today, 14th September 2020, the Royal Astronomical Society (RAS) held a virtual press conference via Zoom for what could be one of the most significant discoveries in decades. A group of researchers from MIT, the University of Manchester and University of Cardiff have found a gas called phosphine in the atmosphere of Venus. They madeContinue reading “Could There Be Life On Venus?”
Mars 2020 Perseverance Rover
Last week, the latest NASA mission to Mars, the Mars 2020 Perseverance Rover, launched successfully from the Kennedy Space Center, Florida. Over the next 7 months, the rover will make its way to the Red Planet. It will land in Jezero crater on 18th February 2021. The mission is known as Mars 2020, due toContinue reading “Mars 2020 Perseverance Rover”
Pluto
If we think back to 2005, Pluto was the 9th planet from the Sun and we knew very little about it. It was a dark distant dot far out in the Solar System. Now, Pluto has been reclassified as a Dwarf Planet. Until 2015, the best we could do is generate computer models of theContinue reading “Pluto”
Neptune
Neptune is the eighth and last planet in the Solar System. It is smaller than Uranus and is distinctly blue in colour. Neptune is an ice giant, similar to Uranus, with its atmosphere containing mainly hydrogen, helium and some methane. It orbits the Sun once every 165 years. This means that it has only completedContinue reading “Neptune”
Uranus
Uranus is the sixth planet on our journey through the Solar System. It is a featureless planet and it is known as an ice giant. The reason it is called an ice giant as opposed to a gas giant like Jupiter and Saturn, is that while the planet is composed of mostly hydrogen and helium,Continue reading “Uranus”
Saturn- The Lord of the Rings
Saturn is one of the most beautiful planets. It has spectacular rings, or as Galileo described them, ears. Saturn is the sixth planet from the Sun and the second largest in our Solar System. Saturn is named after the Roman god of wealth and agriculture. Similar to Jupiter, the planet is made primarily of hydrogenContinue reading “Saturn- The Lord of the Rings”
Jupiter
Jupiter is the largest of the planets in our Solar System and is the first of the gas giants. It’s the fifth planet from the Sun. The planet is named after the Roman god Jupiter, who was the god of the sky and thunder. Jupiter is a truly huge planet. It’s mass is approximately 318Continue reading “Jupiter”
Mars – The Red Planet
Mars is the fourth planet from the Sun and is named after the Roman god of war. It is known as the Red Planet due to its red colour. Mars is further away from the Sun than Earth. As such, this means that it takes longer to complete one orbit. Mars takes 687 days toContinue reading “Mars – The Red Planet”
