Ghostlike dusty galaxy reappears in James Webb Space Telescope image      (via sciencedaily.com)     Original source 

Astronomers studying images from the James Webb Space Telescope have identified an object as a 'dusty star-forming galaxy' from nearly 1 billion years after the Big Bang. They have also discovered more than a dozen additional candidates, suggesting these galaxies might be three to 10 times as common as expected. If that conclusion is confirmed, it suggests the early universe was much dustier than previously thought.

Rocky planets can form in extreme environments      (via sciencedaily.com)     Original source 

Astronomers have provided the first observation of water and other molecules in the highly irradiated inner, rocky-planet-forming regions of a disk in one of the most extreme environments in our galaxy. These results suggest that the conditions for terrestrial planet formation can occur in a possible broader range of environments than previously thought.

Researchers develop novel deep learning-based detection system for autonomous vehicles      (via sciencedaily.com)     Original source 

Autonomous vehicles require object detection systems to navigate traffic and avoid obstacles on the road. However, current detection methods often suffer from diminished detection capabilities due to bad weather, unstructured roads, or occlusion. Now, a team of researchers has developed a novel Internet-of-Things-enabled deep learning-based end-to-end 3D object detection system with improved detection capabilities even under unfavorable conditions. This study marks a significant step in autonomous vehicle object detection technology.

Blasts to clear World War II munitions could contaminate the ocean      (via sciencedaily.com)     Original source 

World War II concluded decades ago, but live mines lurking on the ocean floor still pose threats, potentially spewing unexpected geysers or releasing contaminants into the water. Experts conduct controlled explosions to clear underwater munitions, but concerns have arisen over the environmental impacts from these blasts. New results show that the contamination produced by detonation depends on the blast type, with weaker explosions leaving behind more potentially toxic residues.

An astronomical waltz reveals a sextuplet of planets      (via sciencedaily.com)     Original source 

Astronomers have found a key new system of six transiting planets orbiting a bright star in a harmonic rhythm. This rare property enabled the team to determine the planetary orbits which initially appeared as an unsolvable riddle.

Building blocks for life could have formed near new stars and planets      (via sciencedaily.com)     Original source 

While life on Earth is relatively new, geologically speaking, the ingredients that combined to form it might be much older than once thought. The simplest amino acid, carbamic acid, could have formed alongside stars or planets within interstellar ices. The findings could be used to train deep space instruments like the James Webb Space Telescope to search for prebiotic molecules in distant, star-forming regions of the universe.

New astrophysics model sheds light on additional source of long gamma-ray bursts      (via sciencedaily.com)     Original source 

Cutting-edge computer simulations combined with theoretical calculations are helping astronomers better understand the origin of some of the universe's most energetic and mysterious light shows -- gamma-ray bursts, or GRBs. The new unified model confirms that some long-lasting GRBs are created in the aftermath of cosmic mergers that spawn an infant black hole surrounded by a giant disk of natal material.

Astronomers discover disc around star in another galaxy      (via sciencedaily.com)     Original source 

In a remarkable discovery, astronomers have found a disc around a young star in the Large Magellanic Cloud, a galaxy neighboring ours. It's the first time such a disc, identical to those forming planets in our own Milky Way, has ever been found outside our galaxy. The new observations reveal a massive young star, growing and accreting matter from its surroundings and forming a rotating disc.

How do you make a robot smarter? Program it to know what it doesn't know      (via sciencedaily.com)     Original source 

Engineers have come up with a new way to teach robots to know when they don't know. The technique involves quantifying the fuzziness of human language and using that measurement to tell robots when to ask for further directions. Telling a robot to pick up a bowl from a table with only one bowl is fairly clear. But telling a robot to pick up a bowl when there are five bowls on the table generates a much higher degree of uncertainty -- and triggers the robot to ask for clarification.

Composition of asteroid Phaethon      (via sciencedaily.com)     Original source 

Asteroid Phaethon, which is five kilometers in diameter, has been puzzling researchers for a long time. A comet-like tail is visible for a few days when the asteroid passes closest to the Sun during its orbit. However, the tails of comets are usually formed by vaporizing ice and carbon dioxide, which cannot explain this tail. The tail should be visible at Jupiter's distance from the Sun.

Solar activity likely to peak next year      (via sciencedaily.com)     Original source 

Researchers have discovered a new relationship between the Sun's magnetic field and its sunspot cycle, that can help predict when the peak in solar activity will occur. Their work indicates that the maximum intensity of solar cycle 25, the ongoing sunspot cycle, is imminent and likely to occur within a year.
