👩🏽‍💻 I’m Dr. Becky Smethurst, an astrophysicist at the University of Oxford. I love making videos about science with an unnatural level of enthusiasm. I like to focus on how we know things, not just what we know. And especially, the things we still don’t know. If you’ve ever wondered about something in space and couldn’t find an answer online – you can ask me! My day job is to do research into how supermassive black holes can affect the galaxies that they live in. In particular, I look at whether the energy output from the disk of material orbiting around a growing supermassive black hole can stop a galaxy from forming stars.

  1. Thanks Dr. Becky for another Night Sky News chock full of interesting info!
    For those who want to keep up on what Perseverance and Ingenuity are up to on Mars at more regular intervals, I highly recommend the channel of Mars Guy: the channel is run by a genuine Mars Geologist (Steve Ruff at Arizona State U) and describes the latest activities of the Mars Rover and helicopter and their interpretation. The episodes are short and sweet. Its good content!

  2. Hi Dr Becky,
    Could you please make a video on how to research on your topic(astronomy) and write a book from A levels or high school levels?…….
    Please give me your valuable opinion,Thank You…

  3. I simply adore you, Dr. Becky! I’m so happy I found this channel!! You make it easy to comprehend the most confusing concepts. I can’t wait to watch the rest of your videos. Thank you!! 💕

  4. Dr. Becky, can you please watch today's episode of Star Trek: Strange New Worlds (S1e04). Major plot point involves navigating a brown dwarf being sucked into a black hole. Did they get the science right or wrong? The whole thing looked pretty unrealistic to me. They should have been torn apart by the material in the accretion disk since it'd be moving near the speed of light, right?

  5. This is wildly off topic, lol, but what's the riddle here?

    {vec {hat {alpha }}}({vec {xi }})={frac {4G}{c^{2}}}int d^{2}xi ^{prime }int dzrho ({vec {xi }}^{prime },z){frac {vec {b}}{|{vec {b}}|^{2}}},~{vec {b}}equiv {vec {xi }}-{vec {xi ^{prime }}}}{vec {hat {alpha }}}({vec {xi }})={frac {4G}{c^{2}}}int d^{2}xi ^{prime }int dzrho ({vec {xi }}^{prime },z){frac {vec {b}}{|{vec {b}}|^{2}}},~{vec {b}}equiv {vec {xi }}-{vec {xi ^{prime }}}

  6. You can tell your sub atomic physics mates that the three generations of particles they study are solids liquids and gases in the macroscopic world. For example tau decays to muon to electron. Steam decays to water then ice. Nature is simple but people's egos blind themselves as has been the case with this simple explanation which has been a mystery for decades.

  7. Hey Dr. Becky! Love your channel! I had a question and maybe a video idea. I heard an idea from a slightly crazy space YouTuber about putting a big electromagnet in sun synchronous orbit around Mars, so it always stays between Mars and the sun. The idea was to deflect radiation from the solar wind away from Mars so colonization is safer.
    My question is: would that work do you think?
    I have a couple of questions and thoughts about it. Presumably it would be an electromagnet with either solar panels or a nuclear power plant of some description to power it.
    Q1. Assuming it worked, would it prevent or slow down the blowing away of Martian atmosphere? (Maybe even to the point that we could make the atmosphere thicker over time?)
    Q2. Would the satellite stay in orbit around Mars? I’m thinking of the enormous pressure the solar wind would be exerting on the magnetic field, would the satellite be pushed out of its orbit into another orbit or even into Mars? Could that pressure be countered somehow?

  8. Thanks Dr Becky random YouTube algorithm pointed me to your channel and I can now nerd out with space knowledge. New subscriber!!
    I'm in Australia and get up before sunrise each morning for work and have loved seeing the planets all lined up. Looking forward to mid June to see all of our celestial neighbours appear.
    Can anyone recommend a good star map app for tablets??

  9. Where do you live when sunrise in mid May is at four Am??
    Even on the Summer Solstice in the UK it doesn't rise until a quarter to five!
    I think you might mean dawn instead of sunrise…?
    And you didn't even put it in the blooper section at the end….
    😆

  10. Since you asked for names for the black hole, I looked up its location; it's in the constellation Draco. I thought of a few possible names, mostly inspired by the concept of a winking or blinking eye, and I considered a few dragon-related ideas. My offering:
    The Eye of Ra
    This name in mythology is associated with overt power, violence, and feminine balance to Ra's masculinity; prominent social/religious roles include solar, procreative, aggressive and protective. While Sekhmet is well known as a bearer of that title/role, apparently other goddesses (prominent and obscure) have also held it in various times and places.
