Nasa's Webb telescope finds a new tiny moon around Uranus
It was spotted by the telescope's near-infrared camera during observations in February.
We're not sitting on this one, Uranus has another Moon!
Webb discovered an unknown moon orbiting the planet, expanding its known satellite family to 29. https://t.co/uc9CdPnB7w pic.twitter.com/NM9vlAm24H

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.

Nasa scientist believes mystery planet is home to alien life in stunning breakthrough
A NASA scientist has suggested there may be life in the seas of a dwarf planet saying astrobiologists are constantly "surprised" by the level of activity on the outer edges of our solar system. A NASA scientist has hinted at the possibility of life existing in the seas of a dwarf planet, stating that astrobiologists are continually "surprised" by the level of activity on the outer fringes of our solar system. Ceres, a dwarf planet which is technically an asteroid, is classified as a dwarf planet due to its sufficient mass to be shaped by gravity. NASA's Dr David Grinspoon believes there may still be liquid water inside this unusual planet that could support life. It comes as earlier this year NASA unveiled the first pictures of the Sun's eruptions, which cause the Northern Lights. Investigations of the planet have yielded more results than researchers initially anticipated. Speaking to WIRED, Grinspoon revealed: "Recently we sent a space craft there and we found some surprising things." A bright flash of white on the planet suggests there was once water there - as it is a salt deposit. This also implies that the water that existed there may have mirrored the salty composition of our own oceans here on earth. Dr Grinspoon explained: "The most interesting thing was a crater and what we found is that it is a salt deposit and that salt deposit indicates that there was water on the planet.", reports the Irish Star. "This suggests that this was a water world at one point and may still even have liquid water on the inside." He added: "This is very exciting to astrobiologists because it means that dwarf planets like Ceres are places where you could have in the past had habitable conditions on the inside." However, the thrilling news doesn't stop there. Grinspoon suggested that it's not beyond the realms of possibility that the life-supporting conditions observed on the planet may still exist. He said: "Who knows maybe at present some of these planets still have habitable oceans." Dr Grinspoon added scientists are consistently astounded by the findings of their space explorations, saying, "the more we explore the solar system the more we're surprised by the level of activity on some of these worlds that we thought were dead." He mentioned scientists have determined for life to exist, water is necessary, adding "we have experiments that show that the building blocks of life are very easy to create." Ceres, the largest object in the asteroid belt, floats between Mars and Jupiter. This small planetoid is known for its "alien mystery lights" - a term used to describe the strange illuminations emanating from its surface - which have now been identified as salt deposits.

New moon discovered orbiting ice giant Uranus
A new tiny moon has been identified orbiting the planet Uranus, according to NASA. The satellite, spotted by the James Webb Space Telescope, does not have a name yet and has been designated S/2025 U1. First spotted on 2 February by the space-bound telescope, it measures roughly six miles (10km) in diameter and joins 28 other known moons orbiting the icy giant. Maryame El Moutamid, from the Southwest Research Institute in Colorado and lead investigator on the project to study the rings and moons of Uranus, believes its tiny size is likely to be the reason why it has been invisible to telescopes until now. "It's a small moon but a significant discovery, which is something that even NASA's Voyager 2 spacecraft didn't see during its flyby nearly 40 years ago," she said. "No other planet has as many small inner moons as Uranus," said Matthew Tiscareno of the SETI Institute in Mountain View, California, a member of the research team. Mr Tiscareno said the "complex inter-relationships" between Uranus' moons and its faint rings suggest the planet's evolutionary history may have been a chaotic one. The newfound satellite is about 35,000 miles (56,000km) from the centre of the planet, with a near-circular orbit, according to researchers. All of Uranus' moons are named after characters from the works ofShakespeare and Alexander Pope. NASA said the new moon will be named after approval by the International Astronomical Union, which oversees the official naming process for astronomical objects. In 1986, the Voyager 2 probe became the first human-made object to fly past Uranus, giving humanity its first close-up views of the distant planet. The historic encounter yielded more than 7,000 photographs of Uranus and helped scientists discover two new rings and 11 new moons around the planet. The new addition could hint at more tiny moons waiting to be found.
