Spiders on Jupiter? Scientists uncover secret origins of arachnid-like 'demon' lurking on gas giant's moon.

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.

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.

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for Mars missions, was nominated by former President Donald Trump and previously faced a nomination attempt that was withdrawn earlier this year.
