NASA's Artemis II astronauts captured a stunning new image of the Milky Way from lunar orbit. The mission also highlighted challenges in space photography and onboard systems, providing valuable lessons for future deep space exploration.
Two enormous gamma-ray bubbles, stretching 50,000 light-years, have been discovered above and below the Milky Way. Their distinct high-energy emissions and sharp edges suggest a powerful, sudden event in our galaxy's past, possibly linked to its central supermassive black hole.
For 15 years, scientists have puzzled over the origin of the Milky Way's massive gamma-ray emitting Fermi Bubbles. While a supermassive black hole eruption was the leading theory, new research has complicated this explanation, reopening the investigation into these energetic galactic structures.
Scientists have discovered incredibly powerful cosmic accelerators, dubbed PeVatrons, within our Milky Way galaxy. These sources are responsible for the highest-energy cosmic rays ever detected, some reaching energies of 10 peta-electron-volts. The discovery, driven by observatories like LHAASO, is revolutionizing our understanding of our galaxy's violent and energetic nature.
Researchers have developed an AI-powered simulation that models the Milky Way's 100 billion stars 113 times faster than previous methods. This breakthrough dramatically accelerates galactic simulations by using neural networks to predict supernova impacts, reducing a 36-year run time to just 115 days.
February 2026 skies offer a planetary parade and lunar eclipse. Meanwhile, JWST's 'little red dots' may be direct collapse black holes, and new research suggests the Milky Way's center could be a dark matter blob, not just a black hole.
