Scientists announce, through the "Science" journal, that they discover the source of a fast radio burst for the first time. FRB 180924, a non-repeating FRB which was detected in September 2018 using the Australian Square Kilometre Array Pathfinder, originates from a large galaxy known as DES J214425.25−405400.81 located 3.6 billion light-years from Earth.
Binary Aten asteroid (66391) 1999 KW4 and its minor-planet moon make their closest-ever recorded flyby of Earth at 3.2 million miles away. The asteroid will approach even closer at 0.0155 AU (2,320,000 km) from Earth in 2036, and is the largest asteroid to approach Earth until (4953) 1990 MU in June 2027.
NASA's Mars Reconnaissance Orbiter finds the Beagle 2 spacecraft that disappeared in 2003 intact on the surface of Mars. An error had stopped the spacecraft's solar panels from working and communicating back to Earth.
