Explosion-powered hypersonic propulsion systems capable of transporting humans to distant places on the planet, or even into Earth’s orbit, are a long-term dream for many scientists, but this was nothing more than a hypothesis. However, the team has created an experimental system that appears to be the first tangible step towards making this dream a reality. Explosions are a supersonic combustion process in which the released energy travels through matter in the form of a shock wave. This wave presses on the particles of matter, raising their temperature to the point of ignition. The challenge was to control that energy…

Many users of the instant messaging platform, The WhatsApp, He did not like the company’s decision to immediately suspend the account of people who did not accept the new terms of use and privacy. Because of this, the measure will not be mandatory. In this sense, given its inability to block the user from accessing the platform, WhatsApp has decided to restrict some features to those who refuse to accept our Terms of Service and Privacy Policy. The company explained what can be done in these cases. You will not be able to access your chat list, but you will…

JupiterPhoto: AURA / NSF / NOIRLAB / ESA / NASA / International Gemini Observatory Images captured by two different telescopes show the largest planet in our solar system in new light. The Gemini North Telescope in Hawaii and the Hubble Space Telescope captured Jupiter in visible, infrared and ultraviolet light, and revealed the remarkable properties of the atmosphere in detail. This includes superstorms, massive hurricanes and of course the Great Red Spot – the centuries-old storm in Jupiter’s atmosphere that can engulf Earth. This is multi-wavelength astronomy at work. Seeing a planet with different wavelengths of light can reveal aspects…

An exploding meteor, classified as a “fireball”, was seen crossing the Midwestern sky of the United States on Sunday morning (9). At least 11 cameras recorded the moment of the explosion, around 1:04 am (Brasilia time).Videos captured by security cameras, smart doorbells, or doormats – and even the car – show the way Wonderful brightness The meteor, followed by a beautiful streak of blue and green explosions that illuminate the surroundings.Check out some of the following videos: The meteorite is classified by scientists as a thunderbolt: a “fireball”, leaving an ionized effect, very luminous and long lasting, and in the…

University of Chicago / clone Angela Filila Olento teaching at the University of Chicago Astronomical particle physics currently studying at the University of Chicago, USA, Angela Filila Ollento, became a member of the American Academy of Arts and Sciences, a title already awarded to Albert Einstein, Martin Luther King, Winston Churchill, Nelson Mandela, Charles Darwin and many others. Angela holds a degree in Physics from PUC-RJ and a PhD in Physics from Massachusetts Institute of Technology. “In college, I became interested in particle physics, and at my Ph.D., in astrophysics. From my postdoctoral stage onwards, I dedicated myself to building…

a The WhatsApp It decided that until Saturday (15) its users must decide whether or not to accept the new terms and conditions for using the app. One of the main changes is the exchange of information WhatsApp account data Such as The social networking site Facebook, The parent company of Correspondence Service. Not only will this happen in the European Union and the United Kingdom. After this period, those who do not accept the new terms will start using the app in a limited way. “No account will be removed,” WhatsApp said on its website. But what can change…

a space ship Osiris Rex Coming Home. After nearly five years in space, the ship is back, and with it Rock and dust samples For asteroid Benno. OSIRIS-REx started engines with full steam for seven minutes and covered a distance of approximately 300 million km at 17:23 (Brasilia time) on Monday (10). This was the spacecraft’s most important maneuver since its arrival at Benno in 2018, according to it NASA. When the engines were started, the Osiris-Rex was pushed away from the asteroid at a speed of nearly 1,000 kilometers per hour. It would take two and a half years…

This Sunday (9), and SpaceX It launched another 60 Starlink satellites into orbit, reaching a total of 180 units launched in less than two weeks.The launch also set a new record in the history of the Falcon 9 rocket, whose tenth propeller had boarded its flight – this was the first time a class rocket propeller had managed Orbiting can perform 10 missions, so SpaceX has reached a historic milestone in comparison to its reusable missiles. The launch took place at 3:42 a.m. Brasilia Time, Cape Canaveral. After leaving the platform, the missile performed a maneuver to maintain the necessary…

The social networking site Facebook Twitter The WhatsApp Sony Group Corporation. A group of analysts alerted (trans Bloomberg) That the PS5 will remain in short supply until 2022, indicating that the company is limited in its ability to increase console sales targets. When financial results were announced at the end of April, Sony said it had sold 7.8 million controllers as of March 31It plans to sell at least 14.8 million units in the current fiscal year. This should keep it keeping pace with the popular PS4, which has sold more than 115.9 million units to date. In summary after…

distance Centuries practice harmful postures On planet Earth, humans seek to come to terms with the environment by searching for technologies that allow reversing the damage caused by Global WarmingWhich threatens the spread of endangered species. With this, the latest innovation is a revolutionary machine powered by renewable energy that allows for Arctic glaciers re-freeze, In a way that enhances the survival of the animals that live there – orcas, penguins and polar bears are examples, and the latter are considered endangered species.This machine, which has been dubbed the “refrigeration machine”, was developed by a group of students from Bangor…
