Comet 3I/ATLAS reaches its closest point to Earth tonight: How to see it in the sky and online

Astronomers have detected a unique cosmic collision approximately 25 light-years from Earth, initially mistaken for a new exoplanet. This event marks a significant observation in the field of astronomy, highlighting the dynamic interactions occurring in space.

A recent study suggests that administering immunotherapy earlier in the day can significantly enhance survival rates for lung cancer patients compared to treatments given later in the day. This finding highlights the importance of timing in cancer treatment protocols.

Two neutron stars have been identified as the likely progenitors of the first known ‘superkilonova,’ an extraordinary cosmic explosion that occurred 1.3 billion light-years from Earth. This event marks a significant milestone in astrophysics, providing insights into the life cycles of neutron stars and their explosive interactions.

Recent studies suggest that Titan, Saturn's largest moon, may be filled with 'slushy tunnels' rather than a vast ocean, indicating the presence of liquid in a different form than previously thought. This finding builds on earlier spacecraft observations that hinted at an ocean beneath Titan's icy surface.

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.

A recent brain-scan study has identified key components of the brain's navigation system, which may play a crucial role in preventing individuals from getting lost. This research sheds light on the brain's mechanisms that assist in spatial awareness and navigation, potentially offering insights into early symptoms of dementia.
