NASA’s InSight lander takes a selfie – this is what it looks like on Mars (InSight is the abbreviation for Interior Exploration using Seismic Investigations, Geodesy and Heat Transport). With its solar panels deployed, InSight is about the size of a small bus.Continue reading InSight Lander Takes Selfie on Mars
Ignorance is a very, very bad thing. Last week, as North America suffering from extreme cold weather because of a phenomenon called “polar vortex“, Jim Hoft, founder of the American far-right news and opinion website The Gateway Pundit has tweeted that: “It’s a bit cold outside this morning in middle America… Aren’t you glad you aren’t heating your home with a solar panel like nitwit socialist @AOC is demanding?” (@AOC is the American politician and activist Alexandria Ocasio-Cortez here.) What Jim Hoft says is flat-out wrong. Solar panels DO work in the cold. They work by absorbing LIGHT from the sun, not heat.Continue reading Solar Panels work by absorbing LIGHT from the sun, not heat
Here is a quick summary of the Earth’s snow cover between March 2000 and December 2018. These snow cover maps are made from observations collected by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite.Continue reading Snow cover of Earth between Mar. 2000 and Dec. 2018
The polar vortex is a large area of low pressure and cold air surrounding the Earth’s north and south poles. It is the reason why extreme winter conditions are bringing record-breaking cold temperatures to parts of North America.Continue reading Polar Vortex is the reason why the winter is so harsh in North America
On December 16, 1992, eight days after its final encounter with Earth, NASA’s Galileo spacecraft looked back and captured this remarkable view of Earth and the moon.Continue reading A 1992 Family Portrait of Earth and the Moon

This… is… amazing!
Astrophotographer Martin Junius recorded this stunning video of the total solar eclipse on March 20, 2015, during the E-Flight AB 1000. In the video, you can see the shadow of the moon moving across the clouds below. The plane was 35,000 feet (10,600 meters) above the Northern Atlantic / Norwegian Sea when the video was recorded.Continue reading Watch: The shadow of the Moon during a solar eclipse
The Moon is the Earth’s only natural satellite. It is also the fifth-largest natural satellite in the Solar System and the largest among planetary satellites relative to the size of the planet that it orbits. It formed about 4.51 billion years ago from the debris left over after a giant impact between Earth and a Mars-sized body called Theia (this is known as the Giant Impact Hypothesis and is the most widely accepted explanation of the formation of the Moon). This impact happened not long after the Earth has been formed. But, what if that giant impact never happened? What would the Earth without Moon be like?Continue reading Earth without Moon – what would it be like?
According to research published in the journal Earth and Planetary Science Letters, Earth’s oldest rock (which is 4.1 billion years old) has been found in an Apollo 14 sample from the Moon. If confirmed, it’s an amazing discovery.Continue reading Earth’s oldest rock has been found… on the Moon!
