Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have produced the most complete, high‑resolution map of the Milky Way’s center, revealing the cold gas and its 3D motions in the Central Molecular Zone and offering new insights into where and how stars and planetary systems form near Sagittarius A*.
March’s full Moon, the Worm Moon, peaks at 11:38am on March 3 and will appear full around that time. For parts of North and South America, East Asia and Australia, the Moon will pass through Earth’s shadow in a total lunar eclipse, turning a blood-red color (the Blood Moon). The UK won’t see the eclipse as the Moon will be below the horizon during the eclipse. The piece also notes that many cultures assign names to full Moons (e.g., Worm Moon, Crust Moon) to reflect seasonal events.
February’s Snow Moon—the last winter full Moon—will rise in the east and climb high, offering one of the year’s best lunar views. It sits near bright stars and Jupiter, with a potential occultation by Regulus visible from North America; the guide also explains the Moon illusion, highlights its beginner-friendly nature for families, notes lunar rays near Tycho and Copernicus, and invites readers to send in photos.
Researchers propose a Moon–Earth radio telescope network that could reach sub‑microarcsecond resolution, enabling direct shadows of dozens of supermassive black holes. Six strong targets are identified (including M104 and NGC 1052); a 100‑meter lunar dish paired with Earth baselines could detect all 31 candidates, with far‑side sites offering radio‑quiet observations. The approach relies on visibility data rather than traditional images and remains a decades‑long pursuit, but could greatly advance tests of general relativity and black hole imaging beyond current capabilities.
Astronomers using the Hubble Space Telescope and ground-based observatories have found direct evidence of a hidden companion star to Betelgeuse, Siwarha, whose orbital wake through the red supergiant’s atmosphere explains Betelgeuse’s six-year brightness cycle and other variability, with the wake matching predictions from an orbiter that completes a six-year orbit and potentially merging with Betelgeuse in the distant future; findings are published in the Astrophysical Journal.
ESA’s Proba-3 uses two formation-flying spacecraft and the ASPIICS coronagraph to image the Sun’s inner corona, showing the hot, faint yellow halo and three helium-emission prominence eruptions observed during a five-hour window on Sept. 21, 2025. The animation combines ASPIICS data with NASA’s SDO/AIA imagery to illustrate how artificial eclipses let scientists study the corona’s dynamics, including prominences (cooler plasma) erupting into space and the corona’s light from scattered sunlight and helium emission.
