Interstellar

• Astronomers detected erythrulose, a four-carbon sugar, in interstellar space for the first time using radio telescopes in Spain. • The discovery was made in the molecular cloud G+0.693−0.027, located near the center of the Milky Way, analyzing spectral data. • This finding suggests that the ingredients for life existed before stars and planets formed, demonstrating chemical complexity in space.

• Astronomers have detected erythrulose, a type of sugar also found in raspberries, within interstellar space. • The discovery identifies the presence of this specific organic molecule in the vast regions located between stars. • This finding is significant as it provides new insights into the chemical composition of the universe and the distribution of complex organic molecules.

• Scientists at the Southwest Research Institute (SwRI) are developing a new solar wind forecasting method to locate the first plasma boundary of the outer heliosphere. • The team is combining this forecasting approach with analytic and numerical heliosphere models to map the region's characteristics. • This research is critical for NASA’s New Horizons spacecraft, which is currently traveling toward this mysterious boundary of the solar system.

• NASA released observations from the James Webb Space Telescope regarding interstellar comet 3I/ATLAS, captured in December 2025. • The data reveals that the comet's composition is fundamentally different from any objects previously observed within our own Solar System. • This discovery is significant as it provides rare insight into the chemical makeup of other star systems and the materials that travel between them.
