The new study, published in the journal Space Weather, gives precise indicators for how a future mission to Mars should be timed. With sufficient shielding on the Mars-bound spacecraft, a human Mars mission should be shorter than four years to keep the astronauts safe, the study says.
The Sun can also protect future Mars astronauts from the worst radiation.
Back in August of 2017, Cassini stared at Enceladus for 14 hours, looking at the moon’s night side.
Below is a movie sequence of images, garnered from the final dedicated observation of the Enceladus’ geysers by the imitable Cassini spacecraft.
Back in August of 2,017 Cassini stared at Enceladus for 14 hours, looking at the moon’s night side. The movie begins with a view of the part of the surface lit by reflected light from Saturn and transitions to completely unilluminated terrain. About halfway through the sequence, the exposure time of the images changes in order to make fainter features more visible as the light level drops.
Quantum Computing Platform Accelerates Transition from Bulk Optics to Integrated Photonics on a Silicon Chip Smaller Than a Penny
The quantum computing market is projected to reach $65 billion by 2,030 a hot topic for investors and scientists alike because of its potential to solve incomprehensibly complex problems.
Drug discovery is one example. To understand drug interactions, a pharmaceutical company might want to simulate the interaction of two molecules. The challenge is that each molecule is composed of a few hundred atoms, and scientists must model all the ways in which these atoms might array themselves when their respective molecules are introduced. The number of possible configurations is infinite—more than the number of atoms in the entire universe. Only a quantum computer can represent, much less solve, such an expansive, dynamic data problem.
Summary: Researchers have discovered a new molecule that could increase the ultra-fast decision-making capabilities of computers. The simple molecule provides a new electronic circuit element in which complex logic is encoded in nanoscale material properties.

An international team of scientists including researchers at University of Limerick in Ireland has discovered a new molecule that could further increase ultra-fast decision making in computers.
Of the more than 55,000 jobs, Jassy announced, over 40,000 will be in the United States, while others will be in countries such as India, Germany and Japan via its job fair ‘Amazon Career Day.’ In order to learn about Amazon job opportunities, click on their job page: amazon.jobs/in.
Amazon Career Day is a free event on September 16 2021 at 10:00am IST. “This interactive experience is for all job seekers, regardless of your level of experience, professional field, or background – whether you are interested in working at Amazon or elsewhere,” the company said in. a statement.
Jassy, in his first press interview since he ascended to Amazon’s top post in July, said the company needed more firepower to keep up with demand in retail, the cloud and advertising, among other businesses. He said the company’s new bet to launch satellites into orbit to widen broadband access, called Project Kuiper, would require a lot of new hires, too.
A spectacular portrait of the galaxy Centaurus A has been captured by astronomers using the Dark Energy Camera mounted on the Víctor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory in Chile. This galaxy’s peculiar appearance—cloaked in dark tendrils of dust—stems from a past interaction with another galaxy, and its size and proximity to Earth make it one of the best-studied giant galaxies in the night sky.
The galaxy Centaurus A, which lies over 12 million light-years away in the direction of the southern-hemisphere constellation Centaurus (The Centaur), is the leading light of this striking image. This image provides a spectacular view of the luminous glow of stars and the dark tendrils of dust that hide the bright center of the galaxy. This dust is the result of a past galactic collision, in which a giant elliptical galaxy merged with a smaller spiral galaxy. As well as large amounts of gas and dust, Centaurus A’s dust lane contains widespread star formation, as indicated by the red clouds of hydrogen and by the large number of faint blue stars visible at each end of the dust lane.
The proximity and brightness of Centaurus A—it is one of the closest giant galaxies to Earth—make it one of the best-studied objects in the southern hemisphere night sky. Since its discovery in 1,826 scientists have studied the galaxy exhaustively with many different kinds of telescopes, revealing a variety of intriguing features. Radio telescopes reveal a colossal jet of matter spewing outward from the heart of the galaxy. This jet is accelerated to almost half the speed of light by a supermassive black hole at the center of Centaurus A, and its bright emissions at radio wavelengths make this galaxy one of the most prominent radio sources in the night sky. In fact, in July 2,021 the Event Horizon Telescope produced an image of a jet launching from the black hole in Centaurus A, which weighs in at 55 million times the mass of the Sun.
Physicists and engineers have found a way to identify and address imperfections in materials for one of the most promising technologies in commercial quantum computing.
The University of Queensland team was able to develop treatments and optimize fabrication protocols in common techniques for building superconducting circuits on silicon chips.
Dr. Peter Jacobson, who co-led the research, said the team had identified that imperfections introduced during fabrication reduced the effectiveness of the circuits.
Eight states will roll out a feature allowing users to add driver’s license and state IDs to Apple Wallet for iPhone and Apple Watch to use at security at participating airports, Apple announced Wednesday.
Arizona and Georgia are the first states to adopt the feature and Connecticut, Iowa, Kentucky, Maryland, Oklahoma and Utah will follow, though the company did not specify a timeline.
The news comes just months after Apple said at its Worldwide Developers Conference in June that it was working on the feature with the Transportation Security Administration. The update is a crucial step in Apple’s plan to replace physical wallets and will offer more convenience to travelers looking for a touchless airport experience, the company said.
Sri Lanka has declared a state of emergency as the food crisis worsened after private banks ran out of foreign exchange to finance imports.
