一 | 来自詹姆斯·韦伯太空望远镜的第一张图片显示了SMACS 0723星系团的闪亮的星空。这张图片中发生了很多事情，但是如果凝视时间足够长，你可能会注意到，一些星系似乎“变形了”，它们的光线被拉长了。 With Parasakthi inching closer to release, composer actor GV Prakash has offered a key update that shifts the spotlight squarely onto Sivakarthikeyan. The actor has lent his voice to Tharakku Tharakku, the fourth single from the film, a track GV Prakash describes as a rebel anthem. The announcement, shared with a photograph featuring Sivakarthikeyan and director Sudha Kongara, has quickly become one of the most talked about developments surrounding the project.While Sivakarthikeyan has sung in films before, his decision to voice a song in Parasakthi feels particularly deliberate given the film’s political and historical setting. Rather than functioning as a novelty, Tharakku Tharakku appears positioned as an extension of his character’s inner voice, one that aligns performance, ideology, and music.When the lead becomes the voiceParasakthi is set in the nineteen sixties and draws from the Anti-Hindi agitations that swept Tamil Nadu in 1965. Within this context, Sivakarthikeyan singing a rebel anthem adds narrative weight to the soundtrack. It suggests a song that is meant to belong to the character rather than sit outside the story as a standalone musical moment.GV Prakash has already shaped a varied musical landscape for the film. The earlier singles Adi Alaye, Ratnamala, and Namakkana Kaalam explored romance, emotion, and collective aspiration. Tharakku Tharakku, however, seems designed to cut sharper, both musically and thematically. Described as a rebel anthem, the track is expected to channel resistance, urgency, and defiance, qualities that mirror the political climate the film revisits. #SK sings for #parasakthi the rebel song #tharakkutharakku @Siva_Kartikeyan @Sudha_Kongara @DawnPicturesOff pic.twitter.com/1TZ6Yp7Ooa — G.V.Prakash Kumar (@gvprakash) December 15, 2025 Sivakarthikeyan’s vocal presence also reinforces his evolving image as an actor who increasingly gravitates toward roles rooted in social consciousness. Singing the song himself blurs the line between performer and protagonist, allowing the music to function as a direct emotional conduit rather than a decorative addition.A politically charged ensemble dramaDirected by Sudha Kongara, Parasakthi marks her fourth feature after Drohi, Irudhi Suttru, and Soorarai Pottru. Known for her ability to blend strong character arcs with larger socio-political themes, Sudha appears to be using music as an integral storytelling tool rather than a pause in the narrative. She has co-written the film with Arjun Nadesan, with additional screenplay by Ganeshaa and dialogues by Madhan Karky and Shan Karuppusamy.The film is headlined by Sivakarthikeyan and features Ravi Mohan in what is said to be the first antagonist role of his career. Atharvaa plays a key part, while Sreeleela makes her Tamil cinema debut as the female lead. There has also been speculation about Rana Daggubati’s involvement, though the makers are yet to confirm his casting. Details about the characters remain under wraps, adding to the sense of anticipation. The technical team includes Ravi K Chandran as cinematographer, Sathish Surya as editor, S Annadurai as art director, and Supreme Sundar as action choreographer. Produced by Aakash Baskaran under the Dawn Pictures banner, the film has Dev Ramnath as creative producer, with MP Senthel and Rhea Kongara serving as executive producers. Red Giant Movies is handling distribution.With postproduction in full swing and a theatrical release locked for January 14, 2026, Parasakthi is shaping up as one of the most ambitious Tamil films on the horizon. As anticipation grows, Tharakku Tharakku stands out not just as another single, but as a moment where Sivakarthikeyan’s voice becomes central to the film’s political and emotional core.Also Read: AR Murugadoss Spills Details About Sivakarthikeyan’s Madharasi。然而，这并不是望远镜的人为因素--这是现实本身的扭曲，在被拍摄的空间区域内。引力与质量有着千丝万缕的联系，所以一个天体的质量越大，其引力影响就越大。这种力量是我们能站在地球上的原因，也是让地球绕着太阳转的原因。但是它的工作方式比许多人可能意识到的还要奇怪--引力使时空的结构发生了变化。詹姆斯·韦伯澳大利亚数据中心的首席科学家Themiya Nanayakkara 博士告诉 New Atlas：“假设有一组彼此靠近的大质量星系；即星系团。将会发生的是，因为这里的集体质量非常大，它将在周围的空间中产生一个弯曲--当你把一个重球放在床上时，可以在床褥上观察到类似的效果。
二 | 因此，当来自背景星系的光线经过这个区域时，它所要走的路径会被弯曲。这导致背景星系的图像被拉长。”这种现象被称为引力透镜，其影响在韦伯的新图像中清晰可见。ICRAR的天文学家Robin Cook表示：“所有的物质都会在空间产生这些扭曲，包括你和我，但是只有当真正的天文数量的物质作为透镜存在时，引力透镜的效果才会明显，例如，在新的JWST图像中看到的组合星系团。在这些图像中，我们看到来自非常遥远的星系的光线在前景星系团周围弯曲，形成了令人印象深刻和令人费解的弧线。因为星系团并不是完美的球体，这种现象往往会产生奇怪的特征，比如同一个星系的镜像。”顾名思义，引力透镜可以放大非常遥远的天体，包括一些太过遥远的天体，否则就无法看到。这给了天文学家一个令人难以置信的窥视最遥远的空间和时间的机会。澳大利亚联邦科学与工业研究组织空间与天文学部的 Ray Norris 教授说：“这里的关键特征是，引力透镜不仅扭曲了光线，而且还放大了光线，就像一个望远镜。因此，如果你用JWST通过引力透镜观看遥远的宇宙，就好像你在JWST上安装了一个额外的镜头，让你看到比没有引力透镜更遥远的星系。”而詹姆斯·韦伯太空望远镜特别适合于利用这一现象。澳大利亚国立大学天文学和天体物理学研究学院院长Matthew Colless教授解释说：“使JWST特别善于利用这一现象的因素与使它擅长许多事情的因素相同：一个在红外波长下工作的大镜子。大镜子有两个方面的帮助，因为它不仅可以收集更多的光（所以可以看到更暗的东西），而且可以产生更清晰的图像（所以可以看到更小的东西）。在红外波长下工作也很有帮助，因为红移效应意味着宇宙中非常遥远的天体的光线会沿着光谱从可见光移到红外线。
三 | 由于天文学家在引力透镜的帮助下观察的目标是微弱的、小的和非常遥远的，JWST比在可见光波长下工作的较小的望远镜，如哈勃，有很大优势。”人们可以从詹姆斯·韦伯的空前威力中学到很多东西，结合引力透镜，它可以让天文学家研究宇宙在大爆炸后很早的时候的情况。“JWST已经在对宇宙中形成的第一代星系中的一些星系进行成像，”ARC未来研究员Cathryn Trott教授告诉 New Atlas。
四 | “它也有能力拍摄它们的光谱，据此，来自星系的光被分成其组成波长，使天文学家能够识别个别元素。来自SMACS 0723领域的凝聚星系的光谱已经向我们显示，在宇宙最初几亿年内形成的星系有氧气，这种元素只在恒星内产生。这些观测结果，结合使用低频射电望远镜对原始氢气的观测，如默奇森广域阵列，告诉我们宇宙中第一代恒星是何时形成的，以及星系如何从JWST观测到的小而结实的星系，演变到今天我们周围的星系。”“而且我们还可能通过测量光在引力透镜周围的旅行时间的差异来获得对宇宙膨胀率和年龄的新的精确测量，如爆炸的恒星或闪烁的类星体，”Colless补充说。“因此，我们预计JWST和引力透镜的结合将成为探索遥远宇宙的一种异常强大的方式。
