An artist's impression of a star circling a supermassive black hole, a repeating event that seems to be at the core of AT2018fykNASA/CXC/M. Weiss Astronomers have observed a supermassive black hole consume a star in two phases and have predicted when it might take a third. If it happens, it could create a fascinating cosmic...
A visual representation capturing the formidable burst of gamma rays, stemming from an explosion in the remote cosmos, which reached Earth on October 9 of the previous year. Last year witnessed an extraordinary celestial event as Earth encountered the brightest flash of light ever recorded in the night sky, unsettling the upper atmosphere in an...
Graphical abstract. Credit: The Journal of Physical Chemistry A (2023). DOI: 10.1021/acs.jpca.2c07955 Scientists from Universidad de Santiago de Chile and the University of Notre Dame have developed a machine learning-based approach to recognize organic compounds by their refractive index at a particular optical wavelength. This method has the potential to automate chemical analysis and make it more...
WISE W4 (22.19 µm) image of the IC 1396 HII region. The BRCs are labeled with their names. Credit: Pelayo-B Utilizing different telescopes, a worldwide group of astronomers has studied into IC 1396-- a close-by area of ionized atomic hydrogen. Outcomes of the research, released October 21st on arXiv.org, yield essential understandings concerning the star...
RIKEN physicists have created an LED that emits in a narrow region in the far ultraviolet that is safe for humans but deadly for viruses and bacteria. Credit: RIKEN RIKEN physicists have engineered an exceptionally efficient LED that is lethal to microorganisms and viruses while being safe for humans. Someday it may help nations overcome...
A spider-shaped biohybrid robot is driven by natural impulses from a fungusCornell University Autonomous vehicles are often considered safer than human drivers, but would you feel comfortable with a mushroom in control? A new type of "biohybrid" robot is designed to move based on signals from a fungus's nervous system. A few decades of human engineering...
A new electron microscope can effectively freeze time, snapping images of events just 1 attosecond longDepositphotos The subatomic world is challenging to visualize not only because of its minute scale but also due to its incredibly rapid dynamics. Physicists at the University of Arizona have now developed the world's fastest electron microscope, capable of capturing...
Artist’s impression of an inhabited exoplanet. (NASA/Jay Freidlander) Given the Milky Way's age and size, we would expect to find intelligent civilizations scattered throughout. But where are they? A recent study suggests these civilizations might be so advanced that we simply can't detect them. Reevaluating the Detection of Extraterrestrial Life If extraterrestrials were observing Earth, they might...
NASA's Solar Dynamics Observatory snapped a photo of a solar flare on May 9, 2024. The image combines three extreme ultraviolet light wavelengths to showcase the scorching material in flares, colored in green, blue, and red. Credit: NASA/SDO NASA's Solar Dynamics Observatory spotted a significant solar flare on May 9, 2024, reaching its peak at...
JWST captured a near-infrared image of the boundary of the Horsehead Nebula. (Credit: ESA/Webb, NASA, CSA, K. Misselt/University of Arizona, and A. Abergel/IAS/University Paris-Saclay/CNRS) A fresh perspective has just unveiled a renowned feature in our planet's sky. Mid- and near-infrared investigations conducted by the James Webb Space Telescope have revealed never-before-seen characteristics in the Horsehead Nebula...
