A | 在他们的观测中，天文学家注意到，这个“棉花糖”世界，正如许多人所认为的那样，似乎比我们之前探测到的任何其他气态巨行星的密度都要低得多。 Diljit Dosanjh’s first look from Border 2 has arrived and it sets a powerful tone for what the film aims to deliver. The poster places him in the cockpit of a fighter jet during an intense air battle, with sparks and enemy fire lighting up the frame. His calm but fierce expression as an Indian Air Force officer gives a clear sense of the scale and seriousness of his role. The makers also confirmed the release date of January 23 2026 with this reveal. View this post on Instagram A post shared by tseriesfilms (@tseriesfilms) Sharing the look, T Series posted with caption “Iss desh ke aasmaan mein Guru ke baaz pehra dete hain.” The image shows Diljit with blood on his face, surrounded by the chaos of war as enemy planes target his damaged jet. The raw detailing adds a gripping edge to the visual. Suniel Shetty, who was part of the original film reacted to the post with clapping and heart emojis, adding to the buzz. Diljit also released a short video where he walks out of an airbase hangar in full uniform with the name tag NJS Sekhon. The classic song Sandesa Aaya Hai plays in the background which instantly takes viewers back to the emotional memory of the first Border. The combination of his look, the setting and the music gives a strong patriotic pull. Directed by Anurag Singh, Border 2 builds on the world created by JP Dutta in the 1997 film that centred on the Indo Pakistani War of 1971. While the earlier film starred Sunny Deol, Jackie Shroff, Suniel Shetty, Akshaye Khanna, Puneet Issar, Sudesh Berry and Kulbhushan Kharbanda, the new chapter introduces a fresh ensemble with Sunny Deol, Varun Dhawan, Ahan Shetty, Mona Singh, Medha Rana and Sonam Bajwa. The sequel aims to expand the scale while staying true to the emotion that made the original memorable. ALso Read: Photos: Diljit Dosanjh Turns Heads at International Emmys in Shimmery Tuxedo。
B | 此外，它与它所环绕的红矮星的距离很近，这引起了关于该行星形成的更多问题。卡内基科学研究所地球和行星实验室的研究员Shubham Kanodia在NOIRLab共享的新闻稿中说：“传统上认为红矮星周围的巨行星很难形成。天文学家已经开始称这是一个‘棉花糖’世界，原因是这个气态巨行星具有与棉花糖相似的密度。
C | ”但是，这个气气态巨行星究竟是如何变成如此低的密度的，这让科学家们感到困惑。
D | 然而，他们已经为这个“棉花糖”世界的密度提出了至少一个可能的原因。
E | 而这个理由可能与该行星的岩石核心有关。据信，气态巨行星开始时是巨大的岩石核心，质量是地球的10倍。从那里，它们迅速拉入大量邻近的气体，形成我们今天所知道的“巨无霸”。其他的气态巨行星，如木星，甚至可能因吞噬其他行星而长到如此大。这颗被称为TOI-3757 b的行星有可能在其核心内有较低的重元素丰度，因此岩质核心形成得更慢，推迟了气体吸积的开始。未来对这个“棉花糖”世界的观察（也许用詹姆斯-韦伯太空望远镜）可以告诉我们更多关于它的大气和密度的信息。研究人员在《天文学杂志》上发表了一篇关于该行星的论文。
