Nasa's Webb telescope finds a new tiny moon around Uranus
The new member of the lunar gang, announced on Tuesday by Nasa, appears to be just six miles wide.
It was spotted by the telescope's near-infrared camera during observations in February.
Scientists think it hid for so long — even eluding the Voyager 2 spacecraft during its flyby about 40 years ago — because of its faintness and small size.
Uranus has 28 known moons that are named after characters from Shakespeare and Alexander Pope.
About half are smaller and orbit the planet at closer range.
This newest addition, still nameless, ups the planet's total moon count to 29.

SpaceX to launch secretive US military spacecraft
A SpaceX Falcon 9 rocket will blast into space tomorrow morning, carrying the US military's secretive X-37B drone on its eighth mission. The rocket is due to launch at 5.50am Irish time, according to SpaceX, which said a backup window is available at the same time the following day. The U Space Force has said the drone's mission will include "a wide range of test and experimentation objectives". "These operational demonstrations and experiments comprise of next-generation technologies including laser communications and the highest performing quantum inertial sensor ever tested in space," the service said in a statement last month. "Mission 8 will contribute to improving the resilience, efficiency and security of US space-based communications architectures," it added. About the size of a small bus, the X-37B US space drone looks like a mini version of the manned space shuttles retired in 2011. On previous missions, the X-37B has carried out tests for US space agency NASA. In operation since 2010, the X-37B Orbital Test Vehicle was designed for the Air Force by United Launch Alliance by Boeing. It is 9 metres long, has a 4.5 metre wingspan and is powered by solar panels.

Watch: Fireball lights up night sky in Japan
A flashing fireball dashed across the skies of western Japan, shocking residents and dazzling stargazers, though experts said it was a natural phenomenon and not an alien invasion. Videos and photos emerged online of the extremely bright ball of light visible for hundreds of kilometres shortly after 11pm (3pm Irish time) local time yesterday. "A white light I had never seen before came down from above, and it became so bright that I could clearly see the shapes of the houses around us," Yoshihiko Hamahata, who was driving in Miyazaki Prefecture, told NHK. "It seemed like daylight. For a moment, I didn't know what had happened and was very surprised," he told the public broadcaster. Toshihisa Maeda, head of Sendai Space Museum in the Kagoshima region in southwestern Japan, said that it was a fireball, an exceptionally bright meteor. "It seemed to have gone into the Pacific," he added. "People reported feeling the air vibrate," he said. "It was as bright as the Moon." Objects causing fireball events can exceed one metre in size, according to NASA. Fireballs that explode in the atmosphere are technically referred to as bolides, although the terms fireballs and bolides are often used interchangeably.
