NASA scientists have confirmed the detection of an interstellar object entering the solar system, originating from another star system and drifting through space for millions of years. This marks the first time such an object has approached the Sun so closely. Harvard astrophysicists have identified an unusual energy signature on the object, leading to speculation that it could be a nuclear-powered spaceship. Meanwhile, researchers have proposed a more advanced method for searching for alien radio signals, aiming to enhance the hunt for extraterrestrial communications. Additionally, a U.S. nuclear command plane was reported to have conducted an unusual flight near Greenland.
