Interstellar comet 3I/ATLAS will make its closest approach to Earth on December 19, offering scientists a rare opportunity to study material formed around another star system. Discovered in July, it is only the third confirmed interstellar object ever observed passing through our solar system.
America's biggest space agency, NASA, launched Voyager 1 in 1977 to explore the outer planets. Decades later, as it journeys beyond the solar system’s edge, it continues to transmit data — thanks to brilliant engineering and faint signals captured by giant antennas. Its latest signal has left NASA speechless, revealing the mysteries of deep space.
