天文学家首度确认海王星上存在极光现象，由 NASA 韦伯太空望远镜所发现，补上了太阳系四颗巨行星极光观测的最后一块拼图。这也是我们首次直接捕捉到这颗最远行星的极光辉光与光谱特征。海王星位于太阳系边缘，距离太阳约45亿公里，是一颗冰冷巨行星。自 1989 年航海家二号飞掠海王星后，这颗遥远行星便再无太空船造访。如今韦伯太空望远镜首度捕捉到海王星上明亮的极光活动。这项突破得益于韦伯望远镜优异的近红外灵敏度，不仅能拍下极光发出的辉光，还能透过光谱清楚辨识代表极光活动的重要指标：三氢阳离子（H₃⁺）。这种离子也曾在木星、土星与天王星的极光中被侦测到，被视为气体行星极光的重要证据。与地球或木星不同，海王星的极光并不集中于南北极，而是分布在行星的中纬度地区。这是因为海王星具有异常倾斜的磁场结构，其磁轴与自转轴倾斜达 47 度，这一特征最早由航海家二号所发现。 天文館:首度捕捉到海王星極光 NASA's Webb Captures Neptune's Auroras For First Time

A leaked Telegram discussion by 50 so-called crypto influencers has exposed the extraordinary steps they take in order to profit on the back off unsuspecting defi investors. According to a leaked screenshot of the chat, an elaborate plan to defraud defi investors using the worthless “$Few” tokens had been hatched. $Few tokens would be airdropped to some of the influencers who in turn promoted these to unsuspecting followers on Twitter.
What Is Bitcoin?
Bitcoin is a decentralized digital currency that you can buy, sell and exchange directly, without an intermediary like a bank. Bitcoin’s creator, Satoshi Nakamoto, originally described the need for “an electronic payment system based on cryptographic proof instead of trust.” Each and every Bitcoin transaction that’s ever been made exists on a public ledger accessible to everyone, making transactions hard to reverse and difficult to fake. That’s by design: Core to their decentralized nature, Bitcoins aren’t backed by the government or any issuing institution, and there’s nothing to guarantee their value besides the proof baked in the heart of the system. “The reason why it’s worth money is simply because we, as people, decided it has value—same as gold,” says Anton Mozgovoy, co-founder & CEO of digital financial service company Holyheld.
