The discovery could reshape models of cosmic ray transport by showing high-energy particles can stay aligned over vast distances. Black holes share jet threshold - A new Nature Astronomy study reports that black holes of very different sizes may launch jets when accretion drops to about 2 percent of the Eddington rate. This universal black hole jet rule could help explain feedback in X-ray binaries, tidal disruption events, and galaxies. JWST maps weather on alien world - James Webb Space Telescope observations of SIMP 0136 reveal repeating atmospheric patterns that look like three distinct weather states. The JWST study is an important step toward understanding alien weather, cloud structure, and exoplanet atmosphere variability. ISRO and ESA extend partnership - ISRO and ESA have renewed their cooperation agreement through 2032, expanding joint work on space weather and human and robotic exploration. The extension highlights long-term international collaboration between the Indian Space Research Organisation and the European Space Agency. Albania joins growing Artemis coalition - Albania has become the 73rd signatory of the Artemis Accords, backing principles for peaceful, transparent, and sustainable space exploration. The move shows how even smaller nations are helping shape the rules for future Moon and Mars missions. US confirms deployed orbital weapon - The United States has publicly acknowledged that it has a space weapon deployed in orbit, a first in official public confirmation. The statement adds new urgency to debates over space security, deterrence, transparency, and the militarization of Earth orbit. Ariane 6 delays and orbital traffic - Ariane 6 is facing schedule pressure after a reported turbopump issue, reducing the number of expected launches in 2026. Meanwhile, orbital tracking shows more than 15,000 active satellites around Earth, underscoring the importance of launch reliability and space traffic monitoring. Episode Transcript Pulsar’s giant X-ray particle tail We start with that remarkable pulsar discovery. New observations from China’s Einstein Probe, backed by gamma-ray data from LHAASO, have revealed a 42-light-year X-ray tail trailing away from a pulsar roughly 4,600 light-years from Earth. What makes this especially important is not just the scale, but the shape: the particles seem to stay organized in one direction for tens of light-years, suggesting that high-energy particles do not always scatter randomly through space the way many models assume. Black holes share jet threshold Another big science story today comes from black hole research. Astronomers report evidence for a universal rule that seems to govern when black holes launch jets, whether those black holes are only a few times the mass of the sun or millions of times more massive. The proposed threshold is about 2 percent of the Eddington accretion rate, which gives scientists a surprisingly simple cross-scale rule for one of the most dramatic behaviors in astrophysics. JWST maps weather on alien world From cosmic extremes to atmospheric patterns, the James Webb Space Telescope is giving us a better look at alien weather. Researchers studying the object known as SIMP 0136 found three repeating weather states, with some regions appearing hotter and clearer while others are cooler and cloudier. It is not a forecast in the...
