Scientists discover planet 10 times size of Jupiter orbiting superhot massive stars

Posted by in category: space

Scientists have discovered a planet 10 times as massive as Jupiter orbiting a pair of stars in another solar system, according to new research.

The research, published Wednesday in the journal Nature, points to the discovery of a planet named b Centauri (AB)b or b Centauri b, with an image captured by the European Southern Observatory’s Very Large Telescope in Chile.

The planet is 10 times as massive as Jupiter and “one of the most massive planets ever found,” according to the observatory.

We’ve Found A Unique Giant ‘Tatooine’ Planet That Orbits Two Stars Say Scientists

Posted by in category: alien life

Astronomers just found something unique in the Milky Way–a giant exoplanet in a 200-days orbit around two stars.

In a find that remind us of that binary sunset in the original Star Wars movie, the Tatooine-like “TIC 172900988b” is a Jupiter-sized planet.

Known as a “circumbinary” planet, TIC 172900988b’s existence has been revealed in a paper published in the Astronomical Journal by a team led by Veselin B. Kostov of the SETI Institute.

A Luxurious Swiss Yacht Is Powered by Two Sustainable Fuels

Posted by in categories: solar power, sustainability, transportation

And it offers limitless range.

Zurich-based Swiss Sustainable Yachts has unveiled its new luxurious yacht that is powered by not one but two sustainable fuels, solar and hydrogen. Dubbed Aquon One, the yacht has all the amenities that your heart can desire on a yacht and comes with zero guilt, the New Atlas reported.

Even as cars are going the electric way, maritime transportation is yet to see the same kind of enthusiasm. The first electric ship may have made its maiden voyage, however, the limited range offered by electric batteries is a major challenge that still needs to be overcome. The makers of Aquon One couldn’t agree more and therefore, have opted for a hydrogen fuel cell-powered electric propulsion than massive batteries.

Can an Artificial Intelligence Be Ethical? Researchers Asked AI, and It Sees Both Sides

Posted by in categories: ethics, robotics/AI

Welcome to the future of moral dilemmas.

Not a day passes without a fascinating snippet on the ethical challenges created by “black box” artificial intelligence systems. These use machine learning to figure out patterns within data and make decisions — often without a human giving them any moral basis for how to do it.

Artificial intelligence can create better lightning forecasts

Posted by in categories: climatology, information science, robotics/AI

Lightning is one of the most destructive forces of nature, as in 2020 when it sparked the massive California Lightning Complex fires, but it remains hard to predict. A new study led by the University of Washington shows that machine learning—computer algorithms that improve themselves without direct programming by humans—can be used to improve lightning forecasts.

Better lightning forecasts could help to prepare for potential wildfires, improve safety warnings for lightning and create more accurate long-range climate models.

“The best subjects for machine learning are things that we don’t fully understand. And what is something in the atmospheric sciences field that remains poorly understood? Lightning,” said Daehyun Kim, a UW associate professor of atmospheric sciences. “To our knowledge, our work is the first to demonstrate that machine learning algorithms can work for lightning.”

Parker Solar Probe: A spacecraft has ‘touched’ the sun for the first time

Posted by in categories: physics, space

On April 28, 2021, at 933 UT (3:33 a.m. Eastern Daylight Time), NASA’s Parker Solar Probe reached the sun’s extended solar atmosphere, known as the corona, and spent five hours there. The spacecraft is the first to enter the outer boundaries of our sun.

The results, published in Physical Review Letters, were announced in a press conference at the American Geophysical Union Fall Meeting 2021 on December 14. The manuscript is open-access and freely available to download.
