After winning hearts with his performance as SP Chaudhary Aslam in Aditya Dhar’s Dhurandhar: The Revenge, where fans loved his comical answers and savage attitude, he has officially announced his next big project. Titled Aakhri Sawal, the film will release in cinemas on May 15, 2026. The announcement came through a striking poster that looks intense and powerful. Designed with a giant question mark as its centrepiece, the visual aesthetic features a burnt, gritty look, layered with old newspaper clippings that suggest a story carrying years of historical weight and noise. Adding to the intensity, the poster shows people holding red flags, hinting at themes of protest, anger, and a story that has been building up for a long time.

Along with the visual is the intriguing tagline: "The question India never stopped asking." While specific plot details remain under wraps, the film's foundation goes back in history. Aakhri Sawal draws from the 100-year journey of the Rashtriya Swayamsevak Sangh (RSS), which was founded in 1925 by Keshav Baliram Hedgewar. The story focuses on a specific moment that the film suggests quietly shifted the course of the country and an episode not typically found in standard textbooks. The cast features an ensemble including Amit Sadh, Namashi Chakraborty, Sameera Reddy, Tridha Choudhury, and Neetu Chandra. Sharing the news on social media, Sanjay wrote, "The question India never stopped asking. Get ready to know the answer on 15th May only in cinemas." The announcement received a warm response, with his wife Maanayta Dutt posting fire emojis and fans expressing their excitement over this new project.

三 | 过去的研究在紫外波段发现部分小红点周围存在微弱的延展成分,可能表明存在宿主星系的特征。

四 | 不过,在光学波段(人眼可见光波段)还鲜有证据可以探测到这些结构成分,而光学波段能更明确地揭示恒星质量。 在本项研究中,论文共同通讯作者、武汉大学教授丁旭恒和湖南师范大学特聘教授杨里岚与同事及国际合作者一起,结合詹姆斯·韦布空间望远镜217个小红点的图像,揭示出在单张影像中无法明确检测到的微弱光学发射(延伸至中心天体之外的光)。 研究团队通过数据建模表明,这些光学发射可能来自正在形成恒星的宿主星系,这些星系平均半径仅210秒差距(约685光年),其紧凑程度约为宇宙历史中相近时期其他相似质量恒星形成星系的2.5倍。

五 | 研究团队认为,这些天文学研究发现表明,宇宙小红点并不是孤立的点光源,其周围很可能还存在一个紧凑的宿主星系,这为揭示小红点究竟是什么、又是如何形成的提供了重要线索。 他们也提醒说,本项研究揭示的是小红点这一群体的平均特征。由于其宿主星系发出的光十分微弱,目前在大多数单个小红点中还难以直接探测到。因此,后续研究需要利用更多波段、更深的观测以及更大的样本进一步验证这一发现,并结合光谱信息了解这些宿主星系的性质,进而探索早期宇宙中星系与中心黑洞的共同演化关系。
