NASA Has Discovered 7 Earth-Like Exoplanets on Nearby Star, Possibly Hosts Life

Three of them have all the key ingredients to sustain life.

Astronomers have discovered seven exoplanets the size of the Earth that is orbiting a star, NASA has announced. What’s more interesting about this discovery is that three of those planets are within the habitable zone. This means that they have just the right ingredients to sustain life. Liquid water can be found on the surface of the rocky planets and the temperature is just right.

During a press conference for the announcement of the big news, Michael Gillon, an astronomer from Belgium’s University of Liege, said that the discovery of these exoplanets “is very promising for the search for the search for life beyond our solar system.”

This is also a new record for NASA for having discovered the greatest number of habitable planets orbiting a single star. While all of the planets do have liquid water on the surface, the three that were discovered to be in the habitable zone, or the Goldilocks Zone, are considered the best.

Scientists named the planetary system as TRAPPIST-1 with the habitable-zone planets named TRAPPIST-1e, f and g. Exoplanet “e” bears almost the same size as Earth. In addition, exoplanet “e” also gets the same amount of light from the star like we do.

NASA has discovered seven Earth-like exoplanets orbiting a single star.

Three of them belong in the habitable zone, or the Goldilocks Zone, which has the key ingredients to sustain life.

The seven exoplanets, which are part of the TRAPPIST-1 planetary system, are positioned close to each other.

Which means that when you’re standing on the surface of one exoplanet, the others become very visible.

NASA is planning to launch the James Webb telescope in 2018 and it will find more information about the TRAPPIST-1 planets. The telescope can get data on water, methane, oxygen and possible atmospheres – all of which can help determine the habitability of the planets.

Here’s why NASA’s big discovery of 7 exoplanets is a ‘holy grail’ for astronomers.

Strange Life Forms Were Discovered Trapped Inside Ancient Giant Cave Crystals

And scientists were able to revive them!

Some strange 50,000-year-old microbes were recently discovered inside enormous crystals that lie underground in Mexico's Naica Mine. The ancient microorganisms laid dormant in small liquid pockets inside the crystals for thousands of years and scientists were able to extract and, astoundingly, revive them.

The Naica Mine is full of crystal structures. The sight is breathtaking but do not let such beauty fool you. The place is actually among the most inhospitable places on the planet, with temperatures ranging from 113 to 149°F or 45 to 65°C, and humidity levels greater than 99 percent. The underground environment is also extremely acidic plus light cannot penetrate further than around 1000 feet to 300 meters below the surface.

Since sunlight cannot penetrate the depths of the crystal cave, the microbes were not able to photosynthesize. As such, they performed chemosynthesis, a process where organisms convert inorganic compounds into food using chemical energy. The microbes utilized minerals such as sulfur and iron found in the gypsum crystals.

Here’s What the World Will Look Like Once All The Ice Melted. Pretty Scary!

Major cities will be erased from the maps once this happens.

People have already been warned about climate change and the irreversible effects it has brought to our planet. Global warming is already bad but some of us are still not doing even a single thing to contribute to help Earth become better. One of the most serious effects of global warming is flooding, which can get so bad that major cities could vanish from the maps.

In 2013, National Geographic showed what the Earth will look like if all of the giant ice sheets in the North and South poles would melt. You may still see shades of green and brown on the globe but the snow caps have melted, which result to increase in sea levels and floods and ultimately the disappearance of cities. According to the estimation, the sea levels would increase by 216 feet following the melting of ice caps.

For instance in North America, the entire Atlantic seaboard will be wiped out, and so will Florida and the Gulf Coast. South America’s Buenos Aires, coastal Uruguay, and most of Paraguay would no longer have a place on the map. In Africa, not much land will be lost but climate change will also bring high temperatures which means that this continent will be so hot that most of the regions will become uninhabitable.

Dubai Will Offer the Public Self-Flying Taxi Drones by July This Year

And we thought that only the Jetsons can pull it off!

Dubai is set to take transportation to an entirely different level sometime this year. Mr. Mattar Al Tayer, Chairman of the city's Road and Transportation Agency, revealed at the recently concluded World Government Summit that they are planning to introduce self-flying taxis to Dubai's public transportation system in July.

The drones, which are made in China, will consist of four legs and eight propellers, with two propellers attached to each leg. Each drone can accommodate one passenger weighing at up to 100 kilograms or 220 pounds. On a single battery charge, these self-flying taxis can fly within 50 kilometers or 31 miles and reach maximum speeds of about 160 kilometers per hour.

The self-flying taxi is set to become part of Dubai's public transportation system by July this year.
