10 Wonders of the Solar System These celestial marvels are truly out of this world. Our solar system is big. Way big. In fact, if Earth were the size of a marble, the solar system out to Neptune would cover an area the size of San Francisco. Within this vastness lies an array of celestial wonders: the sun with its surface of plasma, the Earth with its abundance of life and massive oceans, the mesmerizing clouds of Jupiter, to name a few. For this particular list, we've decided to highlight some well-known celestial wonders, as well as a few you might not know about. With new discoveries happening all the time, and so much left to explore, the cosmos is never short on beauty and astonishment. Below are just a few of the scattered jewels of our solar system. The impact crater of Utopia Planitia, Mars The largest recognized impact basin in the solar system, Utopia Planitia features a crater that stretches more than 2,000 miles (about 3,300 kilometers) across Mars' northern plains.

Air Canada Electrifies Its Lineup With Hybrid Planes Do planes with short range make sense in such a big country? Air Canada ordered 30 hybrid aircrafts being developed by Sweden's Heart Aerospace. The carrier also announced an investment in the company. "Air Canada has taken a leadership position in the industry to address climate change. The introduction into our fleet of the ES-30 electric regional aircraft from Heart Aerospace will be a step forward to our goal of net zero emissions by 2050," said Michael Rousseau, president and CEO of Air Canada. The plane is powered by four electric motors and carries lithium-ion batteries to let it fly with a full load for 125 miles (200 kilometers) in all-electric mode. Then the hybrid generators kick in, extending the range to 250 miles (400 km). With the number of passengers reduced from 30 to 25, they can push the range to 500 miles (800 km). As a Canadian, my first thought was this is a very silly idea—Canada is a big country.

The Auto Industry Alone Will Blow the 1.5-Degree Carbon Budget It's making too many cars between now and 2030. A new study from researchers in Australia and Germany, published by Greenpeace in Germany, finds that internal combustion engine (ICE) light duty vehicles (LDVs, or cars, light trucks, and SUVs) alone could pump out as much as 116 gigatonnes of carbon dioxide. The report, based on current projections by manufacturers, states: "Phasing out the internal combustion engine and fully electrifying LDV sales is necessary by 2030 to stay within a 1.5°C carbon budget. However, the industry’s plans—at least the plans of traditional manufacturers such as Volkswagen, Toyota, Hyundai/Kia, and GM—lead to projections of only 52% of battery electric vehicle sales by 2030." Cue up the commentariat, who will say, "What 1.5-degree Celsius carbon budget? It's already blown." To which we respond that every fraction of a degree matters, every kilogram of carbon dioxide m
