Two spacecraft orbiting Mars captured images of the interstellar object 3I/ATLAS as it passed near Mars, providing rare insights into this ancient comet from another star system, with further observations planned to study its composition and behavior.
Scientists have traced the interstellar comet 3I/ATLAS back to the galaxy's oldest regions, making it potentially one of the oldest objects in the Milky Way, offering a rare glimpse into the galaxy's formation and early universe, while also revealing unusual chemical compositions that challenge current understanding.
Scientists suggest that 'Oumuamua, the first known interstellar object, is a fragment of an icy exoplanet, specifically an 'exo-Pluto' composed mainly of nitrogen ice, representing a new class of objects that may be more common than previously thought.
Harvard scientist Avi Loeb suggests that the interstellar object 3I/ATLAS may be producing its own light, possibly indicating it is a spacecraft powered by nuclear energy, sparking debate about its nature and origin.
This week’s top science images include the sharpest photo of the interstellar comet 3I/Atlas captured by NASA's Hubble, traveling at record speeds, and striking photos of UK seas showing warmer temperatures bringing new marine species like salps and bluefin tuna, along with the Perseid meteor shower and glowing underwater creatures.
NASA's Hubble Space Telescope has captured the most detailed images of interstellar comet 3I/ATLAS, revealing it to be smaller than initially thought, with an estimated nucleus size between 1,000 feet and 3.5 miles. Discovered in July, it is only the third interstellar object observed passing through our solar system, and its origins remain unknown. The comet is traveling at over 130,000 mph and will not pose a threat to Earth during its close approach to the Sun in late October.
