*Astronomers detect ancient signals from the first stars in universe

*Juno’s newest close encounter with the king of planets
Scientists have released the latest data from NASA’s Juno spacecraft’s most recent encounters with the gas giant Jupiter. Data collected during these latest orbits show that massive cyclones surround Jupiter's north and south poles unlike anything encountered anywhere else in the solar system
