A Nearby Star Is Expected to Go Nova This Year. Here's How You Can See It.

  Humans have seen this nova lots of times before. It was first identified by astronomers in the late 1800s, and it bursts about every 80 years.

  Indeed, the explosion heading our way would have taken place thousands of years ago, but requires all that time for the light to reach us.

  Still, it’s worth checking it out – T Coronae Borealis last shone in 1946 and this will be the last viewing opportunity before the early 2100s.

  Very cool.
  That is, until the article says to check out Twitter for how to actually see it.

    Right. I avoid Twitter at every opportunity. I want nothing to do with that cease pit.

    On 20 April 2016, the Sky and Telescope website reported a sustained brightening since February 2015 from magnitude 10.5 to about 9.2. A similar event was reported in 1938, followed by another outburst in 1946.[20] By June 2018, the star had dimmed slightly but still remained at an unusually high level of activity. In March or April 2023, it dimmed to magnitude 12.3.[21] A similar dimming occurred in the year before the 1945 outburst, indicating that it will likely erupt between March and September 2024.

    And if I’m interpreting some of the other content correctly, it’ll come and go in one night? Maybe someone who knows more about these cars confirm or correct me.

    Also …

    Even when at peak magnitude of 2.5, this recurrent nova is dimmer than about 120 stars in the night sky.

    So, maybe a bit anticlimactic. 😞

      So no range of dates then? Still pretty damned cool.

  So, there’s nothing in universe that is longer than “soon”. This prediction of going nova this year, only means it already happened but you can’t see it yet. And since it’s going super nova, that means entire even will be boring anyway. You’ll see a white dot that will increase in intensity during this year and then fade away equally slowly.

  For people wondering about dates, there are none. Just like Beetlejuice is expected to explode soon™, that actually means 3000-10000+ years of waiting. So don’t get your hopes up. Out lives are but a blink in universe. All you can do is be diligent and watch it constantly. Doesn’t mean you’ll see much either since at peak magnitude of 2.5 it will be dim enough that you’ll need telescope to see it.

    Nova, not supernova. Novas happen multiple times. Supernova do not but it doesn’t say supernova. Soon, as in within the next 6 months since its following a cycle that happened about 80 and 160 years ago.

    Visible with unaided eyes for several days (but still dimmer than about 120 stars in the sky), and with binoculars for about a week, according to NASA.

    Did you read the article? Or do you just like talking?
