In all, at least 27 moons circle Uranus, with the four largest ranging from Ariel, at 1,160 kilometres across, to Titania, which is 1,580 kilometres across.The study is the first to detail the evolution of the interior makeup and structure of all five large moons: Ariel, Umbriel, Titania, Oberon, and Miranda.

The flare, classified as X1.2, is the seventh solar flare to hit Earth this year, and was captured by NASA's Solar Dynamics Observatory, which watches the Sun constantly. X-class denotes the most intense flares, while the number provides more information about its strength. The strong solar flare peaked.

They found that the planet's deepest clouds also propagate a tsunami which may be playing a very significant role in the acceleration of Venus's fast-moving atmosphere. The observations, by a group of scientists from the Universities of Seville and Basque Country in Spain, were carried out non-stop for more than 100 days. They detailed their findings in the journal Astronomy & Astrophysics.

If the asteroid, known as 2023 DZ2, were to smash into Earth, it would potentially cause major damage. However, it is likely to make a clean pass speeding by at 28,044 km/h, according to EarthSky. Astronomers at the observatory of La Palma, in the Canary Islands, Spain, discovered the asteroid in late February 2023. It is estimated to be between 44 and 99 metres in diameter.

Building infrastructure in space is currently prohibitively expensive and difficult to achieve. But, StarCrete offers one possible solution, according to the team at the University of Manchester. They used simulated Martian soil mixed with potato starch and a pinch of salt to create he material that is twice as strong as ordinary concrete and is perfectly.

The images revealed a volcanic vent changing shape and increasing significantly in size in less than a year. "I didn't really expect to be successful, but after about 200 hours of manually comparing the images of different Magellan orbits, I saw two images of the same region taken eight months apart exhibiting telltale geological changes caused by an eruption," said Robert Herrick, Professor at the University of Alaska Fairbanks, who led the search of the archival data.

The mission called Dragonfly is due to launch in 2027, and will reach Titan in 2034. Dragonfly carries an instrument called the Dragonfly Mass Spectrometer (DraMS), which will shed light on the kinds of chemical steps that occurred on Earth that ultimately led to the formation of life, called prebiotic chemistry.

Using the Atacama Large Millimeter/submillimeter Array (ALMA) telescope, astronomers detected gaseous water in the planet-forming disc around the star named 'V883 Orionis' about 1300 light-years away from Earth. This water carries a chemical signature that explains the journey of water from star-forming gas clouds to planets, and supports the idea that water on Earth is even older than our Sun.

A team of astrobiologists developed an AI model and tested its ability to look out for sparse life hidden away in salt domes, rocks and crystals at Salar de Pajonales at the boundary of the Chilean Atacama Desert and Altiplano -- one of the driest places on the planet, resembling the features of a Martian surface.

The rays were imaged as the Sun descended over the horizon on February 2, with "rays of light illuminated a bank of clouds". These are also known as crepuscular rays, from the Latin word for "twilight". "It was the first time sun rays have been so clearly viewed on Mars," according to the mission officials. Curiosity captured the scene during the rover's latest twilight cloud survey.
