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。 The teaser of Border 2 was released today at a grand event in Mumbai. Among the cast members present at the venue were Sunny Deol, Varun Dhawan and Ahan Shetty. For Ahan, the film not only marks his return to the theatres after a long gap, but he also has to carry forward his father Suniel Shetty's legacy, who was an important part of the film Border. During the event, the actor spoke about the advice his father gave him regarding his role. Ahan said, "Just be honest with your role, be honest with the character, and just have fun. Go out there and enjoy yourself. Don't think too much about what people have to say, or don't compare it to Border 1. That was the most important." He continued, "I'm grateful for this opportunity. First of all, working with Varun sir and Sunny sir, an absolute legend, who did Border with my father. So I'm also carrying that legacy forward. There is a certain type of pressure, but that pressure will always be there. But like they say, 'baap toh baap hota hai'. So if I can even be 10 per cent of what my father was in that film, I think I'll be able to do justice to the character." Sunny Deol, Varun Dhawan, Diljit Dosanjh and Ahan Shetty play soldiers in Border 2 who are trying to navigate through the 1971 Indo-Pak war. Directed by Anurag Singh and backed by Bhushan Kumar, JP Dutta and Nidhi Dutta, Border 2 brings together a strong cast including Sunny Deol, Varun Dhawan, Diljit Dosanjh, Medha Rana, Mona Singh, Sonam Bajwa and Ahan Shetty. Presented by Gulshan Kumar and T Series along with JP Dutta's production house, the film aims to honour the spirit of Indian soldiers and take audiences through a journey of patriotism, courage and sacrifice. With its release set for January 23 2026, just before the Republic Day weekend, the excitement around Border 2 continues to grow with every new reveal.

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。”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。
C | 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。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”。
D | 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。
E | 研究人员在《天文学杂志》上发表了一篇关于该行星的论文。
