Stephen Hawking thought an asteroid impact posed the greatest threat to life on Earth.
Asteroids are small, rocky objects that orbit the Sun. Although asteroids orbit the Sun like planets, they are much smaller than planets. Asteroids are small, rocky objects that orbit the sun. Although asteroids orbit the sun like planets, they are much smaller than planets.
Focussing on the three types of object featured in the V&A display Renaissance Watercolours: illuminated manuscripts, portrait miniatures and coloured drawings, this film showcases the qualities that made watercolour the medium of choice for many artists during the Renaissance.
A modern-day painting of a pomegranate, using traditional watercolour techniques, by artist Lucy Smith, also demonstrates how watercolour painting remains a versatile medium, ideal for capturing life-like details that help us to record our diverse world.
This is the gateway to all the wonderful things that Sydney Harbour has to offer. Circular Quay in Sydney Cove is bordered by the Sydney Opera House and Royal Botanic Garden on one side and the Sydney Harbour Bridge on the other. It’s also the main ferry terminal in Sydney, making it easy to explore one of the world’s great natural harbours.

Google Maps has taken on competitors like MapQuest, Yahoo and Apple. But after a decade of investing, collecting data and billions of images through Street View, Google has over a billion monthly users. It updated tens of thousands of times a day and has mapped more than 220 countries and territories. Here’s a look at how Google came to dominate maps.

The city of Zurich, a global center for banking and finance, lies at the north end of Lake Zurich in northern Switzerland. The picturesque lanes of the central Altstadt (Old Town), on either side of the Limmat River, reflect its pre-medieval history. Waterfront promenades like the Limmatquai follow the river toward the 17th-century Rathaus (town hall).
The 2021 Toyota Mirai is the second generation of zero emission hydrogen fuel cell electric sedan.
One of the principal aims for the new 2021 Mirai has been to give the car a stronger emotional appeal, making it a car that people will be attracted to by its looks and the way it drives, as well its eco-performance. The new GA-L platform and Toyota’s advances in FCEV technologies have made this possible. Toyota’s new fuel cell stack and fuel cell power converter (FCPC) have been developed specifically for use with the GA-L platform.
The designers have been able to bring all the elements together in the stack frame (including the water pumps, intercooler, air conditioning and air compressors and the hydrogen recirculation pump) with each part made smaller and lighter, while at the same time improving performance. The stack case itself has been made smaller by using Friction Stir Welding, reducing the gap between the fuel cell and casing.
The new Mirai is equipped with lithium-ion high-voltage battery in place of the current model’s nickel-metal hydride unit. Although smaller in size, it is more energy-dense, giving higher output and superior environmental performance. Containing 84 cells, it has a 310.8 rated voltage compared to 244.8, and a 4.0 Ah capacity, versus 6.5 Ah. Overall weight has been reduced from 46.9 to 44.6 kg. The output has improved from 25.5 kW x 10 seconds to 31.5 kW x 10 seconds.
The battery’s smaller dimensions have allowed it to be positioned behind the rear seats, avoiding intrusion in the load compartment. An optimised air-cooling path has been designed, with discreet inlets either side of the rear seats. The environmental benefit of driving the Toyota Mirai go beyond zero emissions to “negative emissions” – the car effectively cleans the air as it moves. A Toyota innovation, a catalyst-type filter is incorporated in the air intake.
As air is drawn into the vehicle to supply the fuel cell, an electric charge on the non-woven fabric filter element captures microscopic particles of pollutants, including sulphur dioxide (SO2), nitrous oxides (NOx) and PM 2.5 particulates. The system is effective in removing 90 to 100% of particles between 0 and 2.5 microns in diameter from the air as it passes into the fuel cell system.
One year since the outbreak emerged in Wuhan, China says it has vaccinated nearly one million people against Covid-19. FRANCE 24 correspondent Charles Pellegrin says while the vaccines have yet to be fully approved for market, authorities have granted permission for their limited use on selected groups of the population.

Big Sur Coast Highway is a section of California State Route 1 through the Big Sur region of California that is widely considered to be one of the most scenic driving routes in the United States, if not the world. It is both a National Scenic Highway and a California Scenic Highway, and was described by Australian painter Francis McComas as the “greatest meeting of land and water in the world.”[4] Condé Nast Traveler named State Route 1 through Big Sur one of the top 10 world-famous streets, comparable to Broadway in New York City and the Champs-Élysées in Paris.
The Big Sur portion of Highway 1 is generally considered to include the 71-mile (114 km) segment adjoining the unincorporated region of Big Sur between Malpaso Creek near Carmel Highlands[2] in the north and San Carpóforo Creek near San Simeon in the south.[3]
