一颗死亡的 NASA 卫星突然发射出强大的射电信号

2025-06-24 00:06 by 另一个艾米

NASA Relay 2 实验通信卫星于 1964 年发射升空,1967 年完全停止运作,之后一直停留在轨道上。将近 60 年后,澳大利亚天文学家使用射电望远镜阵列 Australian Square Kilometre Array Pathfinder (ASKAP)搜寻快速射电暴信号时在 Relay 2 所处位置探测到了短暂而强大的射电脉冲,令他们困惑不已。信号持续不到 30 纳秒,但在短时间内其亮度超过了天空中的所有其他天体。他们一开始以为是新的脉冲星或类似天体,之后发现信号来自于地球轨道上的 Relay 2。他们猜测可能是静电放电之类的事件,或者微陨石撞击产生的带电等离子体云。

Launched in 2013, Telegram allows users to broadcast messages to a following via “channels”, or create public and private groups that are simple for others to access. Users can also send and receive large data files, including text and zip files, directly via the app.The platform said it has more than 500m active users, and topped 1bn downloads in August, according to data from SensorTower.

Look for Channels Online

You guessed it – the internet is your friend. A good place to start looking for Telegram channels is Reddit. This is one of the biggest sites on the internet, with millions of communities, including those from Telegram.Then, you can search one of the many dedicated websites for Telegram channel searching. One of them is telegram-group.com. This website has many categories and a really simple user interface. Another great site is telegram channels.me. It has even more channels than the previous one, and an even better user experience.These are just some of the many available websites. You can look them up online if you’re not satisfied with these two. All of these sites list only public channels. If you want to join a private channel, you’ll have to ask one of its members to invite you.
