In 2006, Planet Earth, the British television series produced by the BBC Natural History Unit “has changed our view of the world”. It was the first nature documentary series filmed in high definition. It took five years in the making and it was the most expensive nature documentary series ever commissioned by the BBC. Now, ten years later, in February 2016, the BBC announced a six-part sequel had been commissioned, titled Planet Earth II. On October 2016, BBC released the new series’ trailer.

What if Mars still had liquid water on its surface and a thick atmosphere filled with clouds, like Earth? How would it look like? Software engineer Kevin Gill of JPL (NASA’s Jet Propulsion Laboratory) wondered this and prepared an image using data from NASA’s Mars Reconnaissance Orbiter (MRO)(1) and Mars Orbiter Laser Altimeter (MOLA)(2). The result is stunning!
Gill picked an arbitrary sea level and used GIMP (a free and open-source raster graphics editor used for image retouching and editing) to paint the features onto the satellite images using these measurements.

The Saffir–Simpson hurricane wind scale (SSHWS) is a 1 to 5 rating based on a hurricane’s sustained wind speed. The Weather Channel meteorologist Mark Elliot prepared a video titled “Why Hurricane Categories Make a Difference” and explained what each category means.

Proxima Centauri b, the Earth-like planet orbiting the red dwarf Proxima Centauri may have oceans, scientists say. The planet was discovered in August 2016 and caused excitement because it’s in the habitable zone of its star, and it’s rocky. And it’s in the Alpha Centauri, the closest star system to us!

Researches of France’s National Center for Scientific Research (CNRS) have calculated the size and surface properties of the planet and concluded it may be an “ocean planet” similar to Earth. There are possibilities, though, it may have continents and oceans like Earth, or its entire surface may be covered by a massive ocean.
Elon Mask, the founder, CEO, and Lead Designer of the private space travel company SpaceX announced that “they are planning to get humans to Mars in six years”. In order to achieve this goal, Musk revealed the Interplanetary Transport System, which aims to reach Mars with a human crew for the first time in history.

Previously I posted two articles titled “If The Moon Were Only 1 Pixel – A Tediously Accurate Map Of The Solar System“, and “A Scale Model of Solar System Drawn in the Desert and the Result is Stunning“. Since the human brain cannot deal with the really large numbers, these articles provide an amazing way to understand how big actually our Solar System is.
Now, I decided to put the Solar System into scale as an infographic. You can see a scaled Solar System below, the planets’ distances from the Sun, and the first flybys over them. Plus some statistics about the planets and our home planet, the Earth.

The Expedition 49* (the 49th expedition to the International Space Station) crew members (Anatoli Ivanishin, Kathleen Rubins and Takuya Onishi) has taken amazing photos of Earth from ISS. Four of them has been published on ISS Facebook page. They are really, really beautiful and awe-inspiring!

A woman’s face, who buried over 3,700 years ago in Northern Scotland has been reconstructed by a team of archaeologists and forensic artists led by Maya Hoole. It was the bronze-age at that time in the area.

In 1987 the remains of an individual (a woman between 18-22 year old) buried over 3,700 years ago were discovered at Achavanich in Caithness in the north of Scotland. She was a member of a European group known as the Beaker people. She has been nicknamed ‘Ava’, an abbreviation of the place -Achavanich- she was found. The site was rescued and excavated by the Highland Regional Council Archaeology Unit. Then, the site was mostly forgotten about over the next three decades.
On August 24, 2016, a group of scientists led by Dr. Guillem Anglada-Escude at the Queen Mary University of London, announced the discovery of a terrestrial exoplanet orbiting the red dwarf Proxima Centauri, the nearest known star to the Sun. Proxima Centauri is a Latin idiom, meaning “nearest (star) of Centaurus” (1). The new planet is named Proxima Centauri b and it is predicted to be orbiting within the habitable zone!

The Okavango Delta is a unique pulsing wetland where the 1,600 km (990 mi) long Okavango River reaches a tectonic trough in the middle of the Kalahari Desert in northern Botswana. Each year approximately 11 cubic kilometers of water spread over the 6,000-15,000 km2 area. It is on the UNESCO World Heritage List as well as one of the Seven Natural Wonders of Africa. (1)
