Hubble Telescope observations have revealed a dense gas wake in Betelgeuse’s atmosphere, confirming the presence of a hidden companion star named Siwarha. The discovery explains the red supergiant’s unusual brightness changes and offers new insight into how massive stars evolve and shed material before becoming supernovae.

NASA’s Artemis 2 mission could launch astronauts around the moon in February, marking the first human flight to lunar space since Apollo 17. The crew will test Orion’s systems on a free-return trajectory and prepare for future lunar landings, paving the way for Artemis 3 and NASA’s goal of establishing a long-term human presence on the moon.

New research suggests the universe may be asymmetric, challenging the long-accepted Lambda-CDM model and standard cosmology principles.

New research suggests dark matter may interact with neutrinos, explaining why cosmic structures today are less clumpy than expected. This subtle interaction challenges the standard Lambda Cold Dark Matter model and could guide particle physics experiments. If confirmed, it would be a fundamental breakthrough, reshaping our understanding of the universe and the evoluti...

NASA’s IXPE has made a breakthrough by measuring a white dwarf star. The findings have revealed fresh details about X-Ray emissions, formations of matter, and more within the Binary system.

Astronomers have confirmed a rare rogue planet, drifting without a star nearly 10,000 light-years away. Using gravitational microlensing, their distance and mass were measured, suggesting that free-floating planets may be abundant across the Milky Way. Upcoming telescopes, including NASA’s Roman Space Telescope and China’s Earth 2.0 mission, are expected to uncove...

Spain’s military communications satellite, SpainSat NG-2, was struck by a space particle while moving toward geostationary orbit. The incident occurred at an unusually high altitude, and the damage remains unknown. Operators have activated contingency plans as engineers assess whether the €2 billion mission can still be completed.

Experiments show RNA, a crucial molecule for life, could form naturally on early Earth with borates stabilising ribose and aiding phosphate production. Protoplanet impacts may have delivered RNA ingredients, supporting the RNA world hypothesis and suggesting life’s building blocks could emerge efficiently on Earth and potentially Mars.

A study shows self-driving cars could prevent more than 1 million U.S. road injuries by 2035, cutting traffic-related accidents by 3.6%. Researchers modelled multiple adoption and safety scenarios, highlighting the potential of AVs to reduce human-error crashes. Future studies on highways are needed to fully assess the public health benefits of autonomous vehicles.

Astronomers have measured the mass and distance of a rogue planet for the first time. Using observations from Earth and the Gaia space telescope, the planet was found to be just under Saturn’s mass and about 10,000 light-years away. The study highlights how free-floating planets are ejected from star systems and improves understanding of planetary dynamics.
