A Apple disponibilizou ontem a quinta versão beta dos sistemas 27 e, no caso do iOS, além de trazer novidades como novos ícones para apps nativos e mais opções de personalização de voz para a Siri, a última atualização fez menção à linha de iPhones que deverá ser lançada entre o final deste ano e o início do ano que vem, composta pelos modelos “18 Pro”, “18 Pro Max”, “Ultra”, “18”, “18e” e “Air 2”.

As referências foram encontradas pela Macworld em arquivos do sistema relacionados aos drivers de bateria do iPhone, limitando-se à exibição dos codinomes desses aparelhos. Nenhuma outra informação sobre esses dispositivos foi localizada.

A lista dos seis codinomes internos inclui:

• V62: “iPhone Air 2”
• V63: “iPhone 18 Pro”
• V64: “iPhone 18 Pro Max”
• V67: “iPhone 18”
• V68: “iPhone Ultra”
• V69: “iPhone 18e”

Algo semelhante ocorreu com o “iPhone Ultra” na quarta versão beta do novo iOS, cujo código incluía referências a um aparelho com múltiplas baterias — algo inexistente hoje e fortemente especulado no caso do primeiro dobrável da Apple.

Em um feito inédito, o tradicional evento de setembro destinado ao anúncio de novos iPhones — cujos preparativos já começaram — poderá dividir os lançamentos da linha “iPhone 18”, restringindo-se inicialmente aos modelos premium, como o “Ultra”, o “18 Pro” e o “18 Pro Max”, enquanto os demais aparelhos ficarão para o início do ano que vem.

New infrared observations of the Eskimo Nebula, a bipolar double-shell planetary nebula in the constellation of Gemini, reveal clumps of dust, ionized gas and expanding shells surrounding a central star.

Stunning new imagery of the distant celestial object NGC 2392, better known as the “Lion Nebula,” has been obtained by NASA’s James Webb Space Telescope.

The cosmic vista captured by Webb reveals a colorful view of the ancient nebula, whose characteristic appearance resembles one of nature’s most respected apex predators, complete with a bushy-looking “mane” composed of hazy stellar gases and objects similar to comets.

The new high-resolution imagery offers one of the clearest and most detailed views of the Lion Nebula ever seen. Previous images captured by Webb’s predecessor, the Hubble Space Telescope, were obtained in 2000, featuring the same celestial feature in visible light.

With the added spectral ranges Webb’s Near Infrared Camera (NIRCam) and Mid-Infrared Instrument (MIRI) can capture, the Lion Nebula now appears in colorful pinks and indigo hues, surrounded by distant galaxies blazing in brilliant orange from across vast cosmic distances, whose light has traveled billions of years to reach our Solar System.

A Lion Roars Across the Cosmos

A particularly striking feature about the new imagery is the way cosmic dust and regions of ionized gas are showcased in the new Webb imagery.

“It’s taken several thousand years for this collection of gas and dust to reach its current shape, and the nebula’s components continue to be altered,” read a portion of a statement released by the European Space Agency (ESA) that accompanied the new images.

One reason that helps account for the changing appearance of the Lion Nebula over time can be found at its center, where the remnants of a slowly dying white dwarf star (which effectively forms the nose in the lion’s face after which the nebula is named) continues to supercharge the surrounding cosmic structures made visible in the new Webb imagery.

The rest of the lion’s face is composed of an expanding bubble of ionized gas, the nature of which remains somewhat mysterious. Presently, astronomers are uncertain about what exact mechanisms give rise to the complex appearance of this gassy bubble and its internal structures, which are a recurring element in ancient nebulae such as this.

NGC 2392 isn’t the only celestial feature known as the “Lion Nebula.” An entirely separate diffuse nebula located in the Cepheus constellation, known as Sharpless 2-132, also shares this nickname due to its shape, which resembles a lion’s body seen from the side.

A Cosmic Visage Frozen in Time  

For now, the Lion Nebula is captured in the Webb imagery, which, despite its almost serene beauty, represents a highly active area of the cosmos, undergoing constant change as material is continually ripped away from the stellar central core.

Sometime in the next 10,000 years or so, this striking celestial feature will eventually be destroyed, once the white dwarf powering the nebula completely dies and the remnants of stellar material are completely dispersed into the surrounding space.

Until then, this remarkable cosmic feature will remain a target of study by astronomers, whose inquiries are helped significantly by the unprecedented clarity offered in the latest Webb images.

Additional information about the Lion Nebula (NGC 2392) can be found on NASA’s official page documenting the Webb MIRI imagery.

A stunning new image from the NASA/ESA/CSA James Webb Space Telescope reveals a comet-shaped cloud in the Carina Nebula hiding a cluster of about 70 young stars, including a rare giant of O-type nearly 19 times as massive as the Sun.

A new school year brings fresh opportunities to get involved with NASA. Whether you’re curious about space or eager to build real STEM skills, NASA offers a world of experiences putting you close to the action. As we enter a new golden age of exploration, there’s no better time to jump in, try something bold, and see where your curiosity takes you.

Gain Hands-On NASA Experience

NASA opens the door to authentic mission experiences through internships and student challenges. As members of the NASA team, interns work on genuine agency projects and gain industry-ready skills, all with the guidance of NASA mentors. Visit NASA’s internships website to learn more about current vacancies, deadlines, eligibility requirements, and more.

Through NASA’s student challenges and competitions, student teams tackle some of the critical technical hurdles facing mission planners.
