New Spacecraft Designed To Search Aliens Nearby
A new spacecraft is developed to solve the many attempts to travel beyond our solar system to search for aliens. One of the greatest challenge is on how to slow down the space crafts we send into outer space. In a study published today, astronomers from the Max Planck Institute of Solar Research claim that they have found a way to set it into orbit once it arrives.
This is not the first attempt to send a spaceship to our closest stellar system, Proxima Centauri. Last year Stephen Hawking’s Breakthrough Starshot, aimed to build and sending a prototype of a light-propelled spaceship to the region. However, the problem was that the prototype, which is based on a probe fitted with a light sail. Would not have ways of slowing down once it reached the region.
An interstellar sail is a lightweight probe, pushed by the photon pressure of starlight. Protons in space push the sail, identical to winds on Earth. The small silicon chip spacecraft would travel at one-fifth the speed of light.
Astronomers propose a sail that would be accelerated by the starlight from the sun. The probe would be able to orbit the planet within 100 years. Many believe that that if alien exists, this system is the best chance to discover it. Four light years away, researchers were able to find a planet. The planet named Proxima b, orbits its host stars in the habitable zone.
The planet is believed that could potentially have water on its surface. It is the first exoplanet most identical to Earth that was ever discovered. Hippke told Wired, if the sail has sensors on board, it could detect life on Proxima b. Simulations show that the probe could reach the star with estimated at 96 years.
According to Inverse, current design for the Starshot nanocraft calls for the use of light sails to propel them forward. Researchers at NASA and the Korea Institute of Science and Technology are currently working on the improvements of the first Starshot light sail probe. The development of the new spacecraft raises concern whether something valuable will be found when the probe reaches the Alpha Centauri.
Twins Might Inherit Genetic Error From Dead Mother
Twins that dreadfully lost their mother to a rare genetic cancer night have inherited the genetic error and is now in the search for possible cures. Jennie Chinembiri and her brother James Williamson, the twins have undergone gruelling treatment after they discovered that they were carriers of the genetic error that took their mother’s life.
Bullying In Schools Could Cause Inferior Academic Achievement
In a study where children were tracked from kindergarten through high school found that bullying in schools could cause inferior academic achievements. It could also lead to losing of self-confidence and dislike of going to school.
HIV Vaccine: Human Trials Show Positive Result
Human trials have shown meaningful advancement towards a development of HIV vaccine. For years, researchers have a hard time looking for HIV cure. Typically, when a virus strikes, the body recognizes the foreign entity and creates antibodies that will destroy it.
