New insights into Sagittarius A* reveal it as a surprisingly stable force in our galaxy's core, where objects like G2, X3, X7, and D9 maintain resilient orbits, challenging the previous belief of inevitable destruction by the black hole.
In a landmark discovery published in Nature, astronomers have detected the first definitive coronal mass ejection (CME) from a small, active red dwarf star. Using the LOFAR radio telescope, they observed a powerful Type II radio burst from the M-dwarf StKM-1262—130 light-years away—marking a turning point in our understanding of space weather beyond the Sun.
In a breakthrough published in Physical Review Letters, physicists have demonstrated that black holes satisfy the third law of thermodynamics: as temperature approaches absolute zero, entropy vanishes—implying black holes possess an isolated ground state, a defining feature of quantum systems. The result resolves a long-standing paradox and strengthens the case that gravity is fundamentally quantum.
As humanity races toward the Moon, Mars, and beyond, a quiet revolution is unfolding in spacecraft propulsion—not in the engines themselves, but in the intelligence that designs and controls them. Artificial intelligence, particularly reinforcement learning, is transforming how we develop and operate advanced propulsion systems, from nuclear thermal rockets to compact fusion reactors.
