NASA's Voyager 2 reaches interstellar space

NASA's Voyager 2 reaches interstellar spaceNASA’s Voyager 2 probe has left the protective bubble around the Sun and is flying through interstellar space, becoming the second human-made object to travel so far, the US space agency said Monday. The announcement came six years after its twin spacecraft, Voyager 1, broke the outer boundary of the heliopause, where the hot solar wind meets the cold, dense space between stars, known as the interstellar medium. Voyager 2 is now more than 11 billion miles (18 billion kilometers) from Earth, having passed the boundary on November 5.

Harvard Scientists Say Aliens May Explain Bizarre Interstellar Object 'Oumuamua (But Probably Not)

Harvard Scientists Say Aliens May Explain Bizarre Interstellar Object 'Oumuamua (But Probably Not)Oddball space rock ‘Oumuamua, discovered over a year ago, is the first interstellar object to visit our solar system and is unlike any comet or asteroid observed before. Two astronomers with the Harvard-Smithsonian Center for Astrophysics (CfA) recently took a closer look at the cigar-shaped object’s unusual acceleration during its trip through our solar system, to figure out what may have caused the unexpected boost in the object’s motion. Such acceleration during orbit is characteristic of comets, because their icy bodies evaporate, expelling water vapor that propels the objects.

Cigar-shaped interstellar visitor 'Oumuamua classified as comet

Cigar-shaped interstellar visitor 'Oumuamua classified as cometThe reddish cigar-shaped object called ‘Oumuamua spotted last year tumbling through space is a comet, scientists said on Wednesday, solving the mystery over how to classify the first interstellar object found passing through our solar system. ‘Oumuamua (pronounced oh-MOO-uh-MOO-uh) initially was pegged as a comet, but it lacks the tail of gas and dust characteristic of many comets, and some scientists argued that it was perhaps a dry asteroid. “It does not display any tail in any observation we obtained,” said astronomer Marco Micheli of the European Space Agency’s SSA-NEO Coordination Centre in Italy, who led the study, published in the journal Nature.
