Take a musical tour of the Solar System with composer Gustav Holst. Listen to seven movements based on astrological interpretations of Mars, Venus, Mercury, Jupiter, Saturn, Uranus and Neptune. Composed between 1914 and 1916, The Planets was Holst’s first large-scale work. It was premièred in London in 1918. Mars When Holst began composing his Planets…
Weather satellites provide a wide variety of information to meteorologists, including images of the Earth’s surface and atmosphere. These measurements are crucial for weather forecasting and climate monitoring. There are two main types of environmental satellites: geostationary and polar orbiting. Both fly in different orbits and provide a range of data for meteorologists. Weather Conditions…
This image from NASA’s Curiosity rover shows what appears to be a sandy floral-like formation on Mars. But planetary scientist Abigail Fraemant says it’s actually a result of minerals and water interacting on the planet’s surface. This image is one of many amazing shots that have been taken of the red planet over the years….
If you love going stargazing, it’s important to know how long after sunset is it dark so that you can take advantage of the time. It’s a great way to unwind and enjoy some of nature’s beauty. It’s important to note that the time it takes to get dark after sunset varies for different parts…
Weather satellites are a type of Earth observation satellite that is used to monitor the weather on the planet. They are a great help to weather forecasters. Weather satellites come in two main types: polar orbiting and geostationary orbiting. A satellite that monitors the weather on Earth. Weather satellites monitor the weather on Earth, providing…
A surprisingly detailed picture of Mercury is emerging thanks to NASA’s MESSENGER mission that spent four years in orbit about the Sun’s innermost planet. Its rocky terrain has similarities to lunar landscapes, but it’s far denser than the Moon, with a metallic core that takes up 61 percent of its volume. Geology Mercury is a…
Weather satellites monitor changes in the climate on a daily basis. They detect rain, cloud cover, snow, ice, sea state, ocean color, air pollution, city lights, and fires. They help monitor the effects of El Nino, the Antarctic ozone hole, and many other events on Earth’s surface. They are used to map the boundary of…
Mars is one of the smallest and driest planets in the solar system, with a year that’s almost twice as long as Earth’s. But it also has a fair share of water—mostly in the form of ice. Seasonal ice caps and gullies abound, along with evidence that the Red Planet once had an atmosphere rich…
Mars is one of the most popular planets in science fiction and has inspired generations of writers. It is also the only planet on which scientists have ground-based rovers and landers that transmit data. Despite its thin atmosphere, which is less than 1% that of Earth, liquid water appears to have existed on the surface…
