Jet from giant galaxy M87: Computer modelling explains black hole observations

Added: 09.11.2021 22:23 | 200 views | 0 comments

An enormous jet of particles emitted by the giant galaxy M87 can be observed astronomically in various wavelengths. Scientists have developed a theoretical model of the morphology of this jet using complex supercomputer calculations. The images from these calculations provide an unprecedented match with astronomical observations and confirm Einstein's theory of general relativity.

Astronomers make most distant detection yet of fluorine in star-forming galaxy

Added: 09.11.2021 22:23 | 219 views | 0 comments

A new discovery is shedding light on how fluorine -- an element found in our bones and teeth as fluoride -- is forged in the Universe. Astronomers have detected this element in a galaxy that is so far away its light has taken over 12 billion years to reach us. This is the first time fluorine has been spotted in such a distant star-forming galaxy.

Healable carbon fiber composite offers path to long-lasting, sustainable materials

Added: 09.11.2021 22:23 | 214 views | 0 comments

Researchers have created a new type of carbon fiber reinforced material that is as strong and light as traditionally used materials, but can be repeatedly healed with heat, reversing any fatigue damage. This also provides a way to break it down and recycle it when it reaches the end of its life.

Making aircraft fuel from sunlight and air

Added: 09.11.2021 22:23 | 210 views | 0 comments

Scientists have built a plant that can produce carbon-neutral liquid fuels from sunlight and air. The next goal will be to take this technology to industrial scale and achieve competitiveness. Researchers now describe how this novel solar reactor functions and outline a policy framework that would provide incentives to expand the production of 'solar kerosene'.

On ancient Earth, it never rained but it poured

Added: 09.11.2021 22:23 | 225 views | 0 comments

In a new study, researchers found that during epochs of extreme heat -- 20 to 30 degrees Fahrenheit hotter than today -- Earth may have experienced cycles of dryness followed by massive rain storms hundreds of miles wide that could dump more than a foot of rain in a matter of hours. The research not only sheds light on Earth's distant past and far-flung future but may also help to understand the climates of exoplanets orbiting distant stars.

Securing data transfers with relativity

Added: 09.11.2021 22:23 | 215 views | 0 comments

To counter hacking, researchers have developed a new system based on the concept of 'zero-knowledge proofs', the security of which is based on the physical principle of relativity: information cannot travel faster than the speed of light. Thus, one of the fundamental principles of modern physics allows for secure data transfer.

Scientists detect signs of water in a galaxy far, far away

Added: 09.11.2021 22:23 | 208 views | 0 comments

Water has been detected in the most massive galaxy in the early Universe. Scientists studying SPT0311-58 found H20, along with carbon monoxide in the galaxy, which is located nearly 12.88 billion light years from Earth. Detection of these two molecules in abundance suggests that the molecular Universe was going strong shortly after the elements were forged in early stars. The new research comprises the most detailed study of molecular gas content of a galaxy in the early Universe to date and the most distant detection of H20 in a regular star-forming galaxy.

An artificial material that can sense, adapt to its environment

Added: 09.11.2021 22:23 | 208 views | 0 comments

Researchers have developed an artificial material which can respond to its environment, independently make a decision, and perform an action not directed by a human being. For example, a drone making a delivery might evaluate its environment including wind direction, speed or wildlife, and automatically change course in order to complete the delivery safely. The material incorporates 3 main functions also displayed by materials found in nature, such as chameleons changing the color of their skin to blend into their surroundings.
