NASA has released stunning close-up images of an interstellar comet that passed within 18 miles of Mars last month. The comet, designated as 3I/Atlas, is believed to have originated in another star system and is now making a brief visit to our solar system. This rare opportunity allows astronomers to study the comet up close and gather valuable insights into its composition and origins.
The comet was tracked by multiple NASA spacecraft, including those near Mars and the James Webb space telescope. The European Space Agency's Juice spacecraft also observed the comet as it approached the sun, but the data from this mission won't be available until February due to the spacecraft's heat shield limiting communication with Earth.
Observations suggest that 3I/Atlas is a massive object, ranging in size from 1,444 feet to 5.6 miles across. Scientists believe that the comet may have originated in a star system older than our own, providing a unique window into the deep past of the universe.
"It's like looking at an old friend," said Tom Statler, a NASA scientist, who added that the discovery is "a window into another solar system" and potentially even more. Statler noted that 3I/Atlas may have originated in a star system older than our own, which would make it one of the oldest objects ever discovered.
NASA officials have dismissed rumors that the comet might be an alien spacecraft, saying that while they are always searching for signs of life beyond Earth, 3I/Atlas is simply a comet. The space agency's associate administrator, Amit Kshatriya, clarified that "3I/Atlas is a comet," and emphasized that NASA's focus remains on understanding the origins and composition of this rare celestial visitor.
