Something massive, with roughly 1,000 times the area of Earth, is blocking the light coming from a distant star known as KIC 8462852, and nobody is quite sure what it is. As astronomer Tabetha Boyajian investigated this perplexing celestial object, a colleague suggested something unusual: Could it be an alien-built megastructure? Such an extraordinary idea would require extraordinary evidence. In this talk, Boyajian gives us a look at how scientists search for and test hypotheses when faced with the unknown.

    Actual scientist, speaking with precision: "one of the most mysterious stars in our galaxy." Marketing person working for TED: "The most mysterious star in the universe".

    I am one of those volunteers and I am really proud. Seeing eclipsing binaries and possible exo planets is beyond fascinating.

    And she is too humble to mention that this star is named after her: Tabby's star. There are not many stars named after people, maybe a hundred in total (and I'm not one of them 😁)

    After watching this, I feel like earth might be the group project of alien students somewhere up there

    Imagine hundreds of years from today maybe this clip will be seen as: "This was the first time we noticed them".....

    alien chef commander : " Bring me this Tabetha snitch "
  • She is very good in her presenation. She is believably direct without being arrogant. Her voice moves and pulls you along. Good job. For her, the audience, the viewers: Merry Christmas and a prosperous new year

    Between October 2019 and December 2019, at least seven separate dips were observed, the deepest of which had a depth of 2%. By the end of the observing season in early January 2020, the star had once again recovered in brightness. The total combined depth of the dips in 2019 was 11%, comparable to that seen in 2011 and 2013, but spread over a long time interval.

    I really love what she ended on. "What will it mean if we find another star like this? And what will it mean if we don't?" If we don't find anything like this again it could possibly rule out natural phenomena, and lean towards a more alien hypothesis.
  • I got in trouble watching this in class, but then I showed my teacher and since it was science class, she let us watch it on the projector. #lucky

    I never thought the photometer would be able to detect this so accurately, I thought that it would be interfered with with all types of stray space signals and everything but it works perfectly

    Mars is currently very visible at night from the UK, and on late night walks with my dog, I often find myself just staring up at it and the stars surrounding it. The word awesome is used far too easily these days, but the sky at night is, truly awesome.

    Great, if we find aliens and they look into our history of extra terrestrial movies, they would see that 90% of the time, we kill them.
  • @aperson22222
    At 2:39 she says " . . . one of the most mysterious stars in our galaxy." That's a far more modest claim than the video's title promises.

    The older I get the more I realise my own ignorance. But, for me the biggest mystery is that of time and time alone must be properly understood before we can get anywhere with understanding anything else. This lady is gentle with us dummies, for which I am grateful; well done!
  • I can't express enough how grateful I am for your channel. Your videos have helped me understand complex scientific concepts in an easily digestible way
  • @EQOAnostalgia
    This is absolutely fascinating! I had read a bit about it, but the way she breaks it down. As soon as i saw that 15% dip in light my jaw hit the ground!
