New NASA, ESA images show 3I/ATLAS getting active ahead of its close encounter with Earth

Comet 3I/ATLAS is set to reach its closest point to Earth overnight from December 18 to 19, 2025, marking a significant event for astronomers and space enthusiasts. This interstellar comet, the third of its kind detected, offers a unique opportunity for observation as it swings by our planet.

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.

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.

Billionaire entrepreneur Jared Isaacman has been confirmed to lead NASA following his second Senate confirmation hearing, which took place on December 3. This nomination comes after a previous attempt during the Trump administration, where he faced significant scrutiny. Isaacman's leadership is seen as critical as NASA navigates challenges in its space program.

Scientists have detected an X-ray glow from the interstellar comet 3I/ATLAS, which extends approximately 250,000 miles into space. This observation was made using two space telescopes, revealing how the comet's gases interact with solar particles as it traverses the inner solar system.

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.

NASA's Parker Solar Probe has successfully mapped an unseen part of the sun's atmosphere during its most active phase, marking a significant achievement in solar research. This data provides astronomers with unprecedented insights into solar dynamics and the behavior of solar material.

The U.S. Senate has confirmed billionaire Jared Isaacman as NASA's 15th administrator with a vote of 67-30. Isaacman, a private astronaut and advocate for Mars missions, was nominated by former President Donald Trump and previously faced a nomination attempt that was withdrawn earlier this year. His confirmation follows a second Senate hearing where he emphasized the need for NASA to accelerate its efforts in lunar exploration to maintain U.S. leadership in space.
