Some exoplanets could be better suited to harbor life than Earth

By: Jak Connor | Science, Space & Robotics | Posted: 1 day, 7 hours ago

Astronomers are constantly searching for life elsewhere in the universe and everyday we move closer to answering that big question - are we alone out here?

Scientists have presented new work at the Keynote Lecture at the Goldschmidt Geochemistry Congress in Barcelona, claiming that they have located several exoplanets that have the required conditions to harbor life. So does an exoplanet need to harbor life? Firstly, scientists and astronomers are looking for planets that come under the 'habitable zone', which means the planet must have a potential for liquid water oceans and possibly breathable oxygen.

 

Dr. Stephanie Olson (University of Chicago) presented this new information and says that "NASA's search for life in the Universe is focused on so-called 'habitable zone' planets, which are worlds that have the potential for liquid water oceans. But not all oceans are equally hospitable-and some oceans will be better places to live than others due to their global circulation patterns."

ISS Astronauts pave paradise and put up a parking spot for spacecrafts

By: Jak Connor | Science, Space & Robotics | Posted: 2 days, 10 hours ago

Two NASA astronauts have taken a leap outside the International Space Station and begun a walk to install a brand new loading bay for future visiting space crafts.

The walk lasted for 6 hours and 32 minutes and astronauts Nick Hague and Andrew Morgan worked together to install the International Docking Adapter-3 (IDA-3) to the space facing side of the station. This successful installation will serve as a literal parking spot for future NASA, SpaceX and Boeing spacecrafts.

 

This marked the first time Morgan has ventured out into the infinite abyss via a spacewalk, and according to Mike Barratt, spacecraft communicator in Mission Control, "Welcome to the club, you did a brilliant job." The ISS crew aboard is currently doing experiments and stem cell differentiation in a zero gravity environment. With this hopeful new found knowledge, NASA, SpaceX and Boeing believe this information will be able to assist the human-race level push to land on Mars.

3 Earth-sized planets found, only 12 light-years away & possible water

By: Jak Connor | Science, Space & Robotics | Posted: 2 days, 11 hours ago

Astronomers have located three Earth-sized planets which are orbiting a neighboring star that is about 12 light-years away.

The scientists estimate that all three of the discovered planets are to be at least 1.4 to 1.8 times the mass of Earth, and that they orbit their star every three to 13 days. To give a digestable example of how short this is, in our solar system, Mercury has the shortest orbit of our Sun at just 88 days. The most interesting part of this three planet discovery is the planet that has been titled as 'planet d', scientists are most interested in this planet because it falls within the star's habitable zone with the possible chance of water existing on the surface.

 

Ignasi Ribas, a co-author on the new paper and a researcher at the Institute of Space Sciences in Barcelona, Spain said "We are now one step closer [to] getting a census of rocky planets in the solar neighborhood". It is extremely difficult to determine if 'planet d' harbors the requirements for life to exist, as scientists need to account for the past of the star its orbiting. It could be possible that the star has ejected large amount of radiation at 'planet d', essentially ruining any possible chance of the planet having a habitable atmosphere.

World's first real-world quantum network built with brand new protocol

By: Jak Connor | Science, Space & Robotics | Posted: 3 days, 9 hours ago

A team of researchers have made a break-through discovery in quantum internet networking, announcing they have developed the first quantum internet protocol.

To understand the achievement that has been made here you must first understand current internet protocols. In classical computing and everyday use of the internet, a collection of software layers which are reffered to as a network stack enables devices to communicate with eachother, an example of this is HTTP. Professor Stephanie Wehner from the research team QuTech describes this by saying "All of us use classical link layer protocols in everyday life. One example is Wi-Fi, which allows an unreliable radio signal-suffering from interruptions and interference-to be used to transmit data reliably between compatible devices."

 

Quantum networking uses the same premise as traditional computing, but is still very different. Due to the differences between classical computing and quantum, the team developed a new "quantum network stack" that is the "world's first link-layer protocol". Since a quantum network uses quantum bits, or qubits to transfer information, a new network protocol had to be developed due to quantum bits not retaining data reliably. This newly developed protocol overcomes those hurdles that quantum level software development was encountering.

Scientists on brink of making & commercializing pollution free energy

By: Jak Connor | Science, Space & Robotics | Posted: 4 days, 5 hours ago

While wide-spread pollution free energy might sound like pipe dream when thinking about how many facets of the world economy uses fossil fuels, we might not actually be that far away from it.

A Canadian group of engineers recently published a new paper detailing a method humans could extract hydrogen from oil sands and fields. This new method could enable a large-scale adoption that would ultimately cause a domino effect into energy market, making it extremely cheap to capture hydrogen instead of expensive. The researchers inject oxygen into the oil fields which then raises the temperature and liberates the hydrogen, filters are then used to separate the hydrogen from the other gases that are present.

 

The commericilization of this new method is already taking place and, Grant Strem, CEO of Proton Technologies has given a statement regarding the discovery "This technique can draw up huge quantities of hydrogen while leaving the carbon in the ground. When working at production level, we anticipate we will be able to use the existing infrastructure and distribution chains to produce H2 for between 10 and 50 cents per kilo. This means it potentially costs a fraction of gasoline for equivalent output".

Tesla will let you rent solar panels for $50 a month in six states

By: Jak Connor | Science, Space & Robotics | Posted: 5 days, 6 hours ago

Elon Musk has announced that in six states residents will be able to rent solar panels from Tesla for an extremely low cost. Say goodbye to high-level electricity bills.

 

 

Musk announced via Twitter over the weekend that Tesla would be re-opening its solar arm for residents in select states. Residents will be able to choose from three different solar panel variabitities and will even have the option of renting setups from Tesla at extremely low costs.

 

Depending on your state, Tesla will rent solar panels to you for as low as just $50 a month ($65 a month in California), this would of course be for the lowest package they offer. It is also detailed on their website that those who sign up can cancel at anytime but a $1500 removal fee will be slid your way to restore the roof back to its previous state. The states that are currently ready for this are: California, Arizona, Connecticut, Massachusetts, New Jersey and New Mexico.

The Romeo and Juliet of Galaxies spotted by NASA's Hubble Telescope

By: Jak Connor | Science, Space & Robotics | Posted: 5 days, 7 hours ago

The Hubble Space telescope is nothing short of incredible, and today we have another breath taking image of two distant galaxies bound for a collision of beautiful cosmic doom.

 

 

The image was released by NASA on their Hubble Twitter account and it showcases an amazing display of two galaxies engaging in a cosmic level dance that will eventually result in their impending doom. Scientists have titled the collision UGC 2369, and we know that they will unfortunately collide due to the gravitational distortion of their shape and the bridge of gas that can be seen transferring from one to the other.

 

The galaxies are about 424 million light-years away, and according to the European Space Agency (ESA), "Interaction with others is a common event in the history of most galaxies. For larger galaxies like the Milky Way, the majority of these interactions involve significantly smaller so-called dwarf galaxies. But every few billion years, a more momentous event can occur." Take our galaxy for example, The Milky Way, at the moment we are currently on a 4 billion year collision course with our neighboring galaxy, Andromeda.

SpaceX's cosmic Roadster driver 'Starman' completes first lap of Sun

By: Jak Connor | Science, Space & Robotics | Posted: 5 days, 10 hours ago

Remember when Elon Musk launched a car into space? Well, that Tesla Roadster and its driver 'Starman' have just completed their first lap around the Sun.

 

space-starman-roadster-star-route-completed_01

 

When checking out the 'Where is Roadster' website we can see that the cosmic driver has finally managed to complete his first orbit around the Sun. Starman took to the skies 557 days ago when SpaceX launched the Falcon Heavy rocket aimed for orbiting the Sun, and according to the travel data the car has clocked 762 million miles.

 

Since the car has traveled 762 million miles, it means that it has exceeded its original 36,000-mile warranty over 21,000 times. If you were hoping to spot the roadster from Earth, you unfortunately won't be able to since Earth is currently positioned on the opposite side of the Sun.

Brain stimulation headset will help treat your depression for $500

By: Anthony Garreffa | Science, Space & Robotics | Posted: 5 days, 13 hours ago

The future of treating depression might not be therapy and medication, but rather a headset that you strap on and stimulates your brain in the right ways. Medical technology company Flow out of Sweden is on the forefront of this new wave of technology.

Flow started back in 2016 with Daniel Mansson, CEO of Flow and a clinical psychologist, founded the company after writing his master's thesis on brain stimulation. Mansson also spent years skating between psychology and software, and thus Flow was born. A new hardware product is now being sold as a medication-free treatment to depression.

 

TechRadar spoke with Mansson, with some hands-on time with the Flow headset. They report that it "looks a bit like a miniature VR headset", sitting on your forehead wiht a band that goes over the top of your head to keep it still. There are two big suction pads that connect to your forehead, with Flow providing single-use cloth pads that sit between your skin and the suction pads.

Elon Musk wants to 'nuke Mars', DOOM dev will lend him the BFG 10000

By: Anthony Garreffa | Science, Space & Robotics | Posted: 5 days, 17 hours ago

Elon Musk must've tipped a few back over the weekend as the SpaceX founder and CEO teased the idea of nuking Mars again... but this time, he has t-shirts. Musk took to Twitter over the weekend with a simple tweet:

 

 

This isn't the first time Musk has talked about nuking the red planet, where four years ago he went on The Late Show With Stephen Colbert and talked about detonating nuclear bombs over the poles of Mars. Musk said this was one of the strategies of making Mars more livable.

 

Better yet, the official Twitter account for DOOM tweets out that they want Musk to use their BFG 10000:
