Astronomers from Cardiff University, UK, have employed the Combined Array for Research in Millimeter-wave Astronomy (CARMA) to explore the nearby Andromeda galaxy. Results of the observational campaign, published December 27 on the pre-print server arXiv, yield important insights into the molecular cloud system of this galaxy. Go to Source Stars and planets are inextricably linked. They form together and stars shape the fate of planets. Stars create the dusty protoplanetary disks that give birth to planets of all kinds. And when a star dies, planets are either blown apart, swallowed, or doomed to spend an eternity in cold and darkness. Go to Source […] One of the main questions in exoplanet science concerns M dwarfs (red dwarfs) and the habitability of exoplanets that orbit them. These stars are known for their prolific and energetic flaring, and that’s a problem. M dwarfs are so small that their habitable zones are in tight proximity to them, putting any potentially habitable planets […] Have you ever found something unexpected in your hamburger? Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) were surprised to discover the very earliest phases of giant planet formation between the dense layers of gas and dust in the “Gomez’s Hamburger” system, referred to as GoHam. This research, currently in preparation for publication, was presented […] A black hole has shredded a massive star like it was “preparing a snack for lunch,” according to a team of scientists at the American Astronomical Society’s annual meeting (5–8 January). Go to Source Ripples spreading across a calm lake after raindrops fall—and the way ripples from different drops overlap and travel outward—is one image that helps us picture how a quantum computer handles information. Go to Source Researchers from the Department of Energy’s SLAC National Accelerator Laboratory and the University of California, Los Angeles (UCLA), have designed innovative technology that can generate both high-energy and high-brightness electron bunches in an accelerator that is a fraction of the size of current particle accelerators. Go to Source Quantum mechanics and relativity are the two pillars of modern physics. However, for over a century, their treatment of space and time has remained fundamentally disconnected. Relativity unifies space and time into a single fabric called spacetime, describing it seamlessly. In contrast, traditional quantum theory employs different languages: quantum states (density matrix) for spatial systems […] Using the Whole Earth Blazar Telescope (WEBT), an international team of astronomers have performed long-term photometric observations of a luminous blazar known as Ton 599. Results of the observations, published in the Astronomy & Astrophysics journal, shed more light on the optical variability of this object.

But from high above, the shape and design becomes unmistakable: Serpent Mound is indeed in the shape of snake. And yet, that’s just the beginning of the mystery which still surrounds this incredible marvel of human achievement. Even the date of Serpent […] YouTube Video Here: https://www.youtube.com/embed/boxCX-NKnR0?feature=oembed&enablejsapi=1 Has modern society continued to advance and progress since ancient times? That’s a general idea given the concept of evolution, but is it necessarily true with humans? If we consider the state of the world, we find civilizations with mostly patriarchal control. We see the rich few control the masses […] Using new observations from NASA’s Hubble Space Telescope and ground-based observatories, astronomers have tracked the influence of a recently discovered companion star, Siwarha, on the gas around Betelgeuse. The research, by scientists at the Center for Astrophysics | Harvard & Smithsonian (CfA), reveals a trail of dense gas swirling through Betelgeuse’s vast, extended atmosphere, shedding […] Small lakes on ancient Mars may have remained liquid for decades, even with average air temperatures well below freezing. Go to Source A team using the NASA/ESA Hubble Space Telescope has uncovered a new type of astronomical object—a starless, gas-rich, dark-matter cloud that is considered a “relic” or remnant of early galaxy formation. Nicknamed “Cloud-9,” this is the first confirmed detection of such an object in the universe. The finding, published in The Astrophysical Journal Letters, furthers […] In May 2024, the strongest solar storm in twenty years raged. An international team led by ETH Zurich observed it. Their findings are now helping to improve space weather forecasts. Go to Source |
