Of all the unanswered questions in modern science, perhaps the most talked about is whether we are alone in the universe. A new paper looks at another way we might be able to detect advanced civilizations, and at its center is the need for energy. Go to Source Using NASA’s Fermi space telescope, Italian astronomers have observed a radio source known as 3C 216. As a result, they detected increased gamma-ray activity from this source, including a strong outburst. The finding is reported in a research paper published on the arXiv preprint server. Go to Source Anyone hoping for a clear path forward this year for NASA’s imperiled Mars Sample Return mission will have to wait a little longer. Go to Source The LUX ZEPLIN (LZ) Dark Matter experiment is a large research effort involving over 200 scientists and engineers at 40 institutions worldwide. Its key objective is to search for weakly interacting massive particles (WIMPs) by analyzing data collected by the LZ detector, situated at the Sanford Underground Research Facility in South Dakota. Go to Source […] The long-awaited detection of gravitational waves has opened up a whole new world of astronomy. One of the key efforts is now to tie signals across multiple domains—for example, a gravitational wave and the associated electromagnetic radiation created by that same event, such as a black hole merger or a gamma-ray burst. Go to Source […] NASA announced Tuesday it may turn to Elon Musk’s SpaceX or Jeff Bezos’s Blue Origin to help reduce the soaring costs of returning Martian rocks collected by the Perseverance rover to Earth. Go to Source US company Firefly Aerospace said Tuesday it is aiming to launch a lander to the moon next week under an experimental NASA program that partners with the commercial sector to reduce costs. Go to Source What “may” be the best anticipated comet of 2025 is coming right up. Right now, there’s only one comet with real potential to reach naked eye visibility in 2025: Comet C/2024 G3 ATLAS. This comet reaches perihelion at 0.094 Astronomical Units (AU, 8.7 million miles or 14 million kilometers, interior to the orbit of Mercury) […] NASA is pitching a cheaper and quicker way of getting rocks and soil back from Mars, after seeing its original plan swell to $11 billion. Go to Source The size and spin of black holes can reveal important information about how and where they formed, according to new research. Go to Source In the next few decades, crewed missions to the moon and Mars will likely become frequent. One of the main challenges faced by these future missions will be the need to protect astronauts from the intense radiation of outer space. Go to Source Galaxies are not islands in the cosmos. While globally the universe expands—driven by the mysterious “dark energy”—locally, galaxies cluster through gravitational interactions, forming the cosmic web held together by dark matter’s gravity. For cosmologists, galaxies are test particles to study gravity, dark matter and dark energy. Go to Source A study published in The Astrophysical Journal Letters, introduces a newly defined “filament channel” function. This new function provides a novel theoretical foundation for predicting solar eruptions by determining whether new emerging flux (NEF) can trigger instability in solar filaments. The study was led by Prof. Lin Jun from the Yunnan Observatories of the Chinese […] An international team of astronomers have investigated a large Galactic supernova remnant designated G278.94+1.35. Results of the study, published Dec. 30 on the pre-print server arXiv, shed more light on the properties of this remnant. Go to Source SpaceX sent up the second launch of the year from the Space Coast on Monday afternoon. Go to Source |
