A man in his 20s was killed and another critically injured after being struck by a hit-and-run SUV while crossing the street in Corona, Queens, early New Year's Day; the driver fled the scene and is being sought by authorities.
New observations from the Daniel K. Inouye Solar Telescope suggest that Alfvén waves, magnetic waves traveling through the sun's corona, carry significant energy that may explain the long-standing mystery of why the sun's outer atmosphere is much hotter than its surface, potentially accounting for at least half of the heating required.
Scientists at the University of Hawai‘i have discovered that changing elemental composition in the Sun's corona drives the phenomenon of solar rain, resolving long-standing questions about how plasma cools and condenses rapidly during solar flares, which could improve space weather predictions.
Astronomers used a rare 'double zoom' gravitational lensing technique to directly measure the size of a black hole's corona, revealing it to be about the size of our solar system, and opening new avenues for studying black hole environments.
Constellation Brands, parent of Modelo and Corona, faces a significant drop in beer sales, especially among Hispanic consumers, leading to a profit and sales warning and a stock price near a 5-year low, with revised earnings and sales outlooks for 2026.
Constellation Brands, owner of Corona and Modelo, reports a 2% decline in beer sales and a 28% drop in wine and spirits, citing economic concerns, inflation, and changing consumer attitudes towards alcohol as key factors. The company is adjusting pricing strategies to address these challenges amid broader shifts in American drinking habits and health awareness.
Corona's parent company, Constellation Brands, reports a 2% decline in beer sales, primarily due to reduced spending by Hispanic customers who are staying home more often amid socioeconomic concerns and immigration policy fears, impacting sales in key markets.
ESA's Proba-3 mission has captured the first images of an artificial solar eclipse using two satellites in precise formation, allowing detailed observation of the sun's corona and phenomena like prominences, which are crucial for understanding space weather and solar physics. This technology enables continuous observation of the corona without waiting for natural eclipses, marking a significant advancement in solar research.
Scientists have achieved the sharpest-ever images of the sun's corona using advanced adaptive optics, revealing new features like delicate coronal rain, a rapidly forming plasma 'plasmoid', and dynamic solar prominences, which could help solve longstanding mysteries about solar heating and space weather phenomena.
The European Space Agency has launched the Proba-3 mission, consisting of two spacecraft designed to create an artificial solar eclipse to study the sun's corona. This mission aims to demonstrate precise formation flying technology and investigate why the corona is significantly hotter than the sun's surface. By blocking the sun's light with millimeter-level accuracy, researchers can observe the corona for extended periods, improving our understanding of space weather and its impact on Earth.
The European Space Agency's Proba-3 mission, launched on December 5, 2024, aims to create artificial solar eclipses using two satellites to study the Sun's corona. By blocking the Sun's light, the mission will allow extended observation of the corona, providing insights into phenomena like Coronal Mass Ejections and solar wind acceleration. This mission also demonstrates advanced autonomous spacecraft operations, potentially transforming future space exploration by using multiple small satellites for complex objectives.
The European Space Agency's Proba-3 mission, set to launch from India, will use two satellites to create artificial solar eclipses, allowing scientists to study the Sun's corona more frequently. The mission involves precise formation flying, with the satellites maintaining a 150-meter distance with millimeter accuracy. This low-cost mission aims to solve mysteries about the Sun's corona, which is significantly hotter than its surface and influences space weather. Proba-3 is part of ESA's series of technology demonstration missions.
Astronomers have successfully determined the structure of black hole coronae, revealing them to be disk-like rather than spherical, using NASA's Imaging X-ray Polarimetry Explorer. This breakthrough provides new insights into black hole dynamics, particularly how they emit energy and interact with their surroundings, challenging existing models and enhancing our understanding of active galactic nuclei (AGNs). The study focused on obscured black holes, allowing researchers to isolate and analyze the corona's high-energy X-ray emissions, which are crucial for understanding black hole behavior and their influence on galaxy formation.
NASA's Parker Solar Probe recently completed a close flyby of Venus to adjust its orbit for a closer approach to the sun, aiming to solve mysteries about the sun's corona. The probe's instruments have revealed that magnetic field phenomena, known as switchbacks, play a crucial role in heating the corona, which is significantly hotter than the sun's surface. Understanding these processes is vital for predicting space weather, which affects satellites and power grids on Earth.
Scientists have, for the first time, observed the shape of a black hole's corona, revealing it to be disk-like rather than spherical, similar to the accretion disk. Using data from NASA's Imaging X-ray Polarimetry Explorer, researchers studied scattered X-rays from obscured black holes, including Cygnus X-1 and X-3, to detect this pattern. This discovery aids in refining black hole models and understanding their role in active galactic nuclei.
