Scientists detect X-ray glow from interstellar comet 3I/ATLAS extending 250,000 miles into space

NASA's Europa Clipper spacecraft has conducted seven hours of ultraviolet observations of the interstellar comet 3I/ATLAS as both the spacecraft and the comet approach Jupiter. This observation is part of ongoing efforts to study the comet's characteristics and behavior in the solar system.

A recent analysis indicates that satellites could start colliding with each other or space debris within three days following a severe solar storm that impairs their maneuverability. This alarming prediction highlights the vulnerability of satellite systems to solar activity, which can disrupt their operational capabilities.

Recent research indicates that sitting by a window can enhance blood sugar control in individuals with type 2 diabetes, as light exposure influences the body's circadian rhythms that regulate glucose levels. This finding highlights the potential for simple lifestyle changes to improve health outcomes for those managing diabetes.

The Orion Nebula will be prominently visible in the night sky on December 18, providing an excellent opportunity for stargazers to observe this celestial feature. The nebula, located in the Milky Way, is a region of star formation and is one of the brightest nebulae visible to the naked eye. Observers can expect to see not only the nebula but also various planets and stars, enhancing the viewing experience.

NASA's Jet Propulsion Laboratory has announced the precise timing of the interstellar comet 3I/ATLAS's closest approach to Earth, which is set to occur tonight. This event marks a significant moment for astronomers as they prepare to observe the comet's features and trajectory during its flyby.

The interstellar comet 3I/ATLAS is set to make its closest approach to Earth tonight, with a free livestream scheduled to begin at 11 p.m. EST on December 18, 2025, weather permitting. This event marks a significant moment for astronomers and space enthusiasts alike as they prepare to observe the comet's features in detail.

The interstellar comet 3I/ATLAS is set to make its closest approach to Earth on December 19, 2025, marking a significant event for astronomers and space enthusiasts alike. This flyby follows its recent close encounter with Mars, where NASA captured new images showcasing the comet's features and trajectory.

New measurements indicate that smoke particles from wildfires, when lofted miles high into the atmosphere, are twice the size of those found at lower altitudes. This finding highlights a significant difference in the behavior of smoke particles depending on their altitude.
