👩🏽💻 I'm Dr. Becky Smethurst, an astrophysicist at the University of Oxford (Christ Church). 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.

DO NOT LOOK DIRECTLY AT ATHE SUN. Please always double check that any eclipse glasses or camera lens/telescope filters you are using pass the ISO 12312-2 international standard and do not have any scratches on them by holding them up to a light in your house first (all you should be able to see through them is the filament of the light bulb).

When stars like the Sun die do their planets survive? In 5 billion years the Sun will swell into a red giant star, swallowing up the Earth, and maybe even Mars. But what about Jupiter and the rest of the gas giant planets? This month new research has been published, claiming to have found two exoplanets in orbit around two dead white dwarf stars with JWST. These planets are similar in mass to Jupiter, and orbit their stars at a distance similar to Saturn and Neptune in the Solar System.

The Supermassive Podcast episode on the Multiverse which inspired this video: audioboom.com/posts/8420475-do-we-live-in-a-multiverse
The sci-fi TV show Rick & Morty uses the idea of a multiverse in its episodes and its a brilliant story. But in terms of the science, does it check out? Well there are two main ways of interpreting the idea of a multiverse in physics (both hypothetical and unproven), either (i) the quantum mechanics many worlds interpretation, or (ii) the bubble universes from eternal inflation. So which one does Rick & Morty explore? And how does it compare to other sci-fi shows employing the idea of a multiverse like Everything Everywhere All At Once, Spider-Man: Into the Spiderverse, Spider-Man: No Way Home, His Dark Materials, Doctor Who, Community (Remedial Chaos Theory and the darkest timeline), and Sliding Doors.

In 1989 the Voyager 2 space probe flew past Neptune and took the canonical image that we're so used to seeing. BUT the blue colour in that image we're so familiar with is actually a FALSE colour. Not what you'd see with your eyes if you were that close. Now those images have been reprocessed with some new data that allows us to make a TRUE colour image, and it turns out Uranus and Neptunes look more like twins...

One of the most distant galaxies known GN-z11 has been observed many times by JWST in it’s first few years of observations but that data isn’t as clear cut as we hoped. There’s a debate going on (led by two camps; one in Cambridge and one in Oxford) over whether GN-z11 has a growing supermassive black hole or not. Either way it has big implications for our understanding of how galaxies and black holes evolve together in the early Universe.

👩🏽💻 I'm Dr. Becky Smethurst, an astrophysicist at the University of Oxford (Christ Church). 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.

Remember those overmassive galaxies that JWST found that people claimed proved "the big bang never happened?" when in reality it was just that we couldn't explain how they'd got so big? Well, turns out those galaxies probably aren't that massive after all. In this video we're chatting about how new JWST observations have found evidence that galaxies in the early Universe form different types of stars at different rates to in the Milky Way (called the Initial Mass Function of stars). This then has knock on effects on the calculation of the masses of these distant galaxies...

The first science images from the Euclid Space Telescope were released last month and they are INCREDIBLE! Of course, lots of you had questions about why the shape of the diffraction spikes around the bright stars were different from either the Hubble Space Telescope or the James Webb Space Telescope, and it’s all to do with the structure of each telescope and how the light moves around it.

One of the biggest mysteries in astrophysics is how supermassive black holes form in the early Universe and grow to be SO supermassive. There's a limit to how fast they can grow in mass, so they shouldn't exist so early in the Universe's history. Yet the James Webb Space Telescope (JWST) and the Chandra X-ray observatory have together just found the most distant supermassive black hole known (at a redshift of z=10.3, meaning the Universe was just 450 million years old when the light left that galaxy). The best estimate we have of the black hole's mass puts it at about the same mass as it's galaxy! Suggesting that perhaps the black hole formed FIRST as direct collapse black hole and then the galaxy of stars formed around it... essentially solving the astrophysics equivalent of: "what came first the chicken or the egg?

The first science images from the Euclid Space Telescope were released today and they are INCREDIBLE! Unlike JWST or Hubble which both focus on details in small areas of sky, Euclid looks at a large area of sky all at once giving incredible images which will be used to map the positions and distances of billions of galaxies in the universe. Astrophysicists will use this map to study where dark matter is in the universe and how the expansion rate of the universe has changed with time.

👩🏽💻 I'm Dr. Becky Smethurst, an astrophysicist at the University of Oxford (Christ Church). 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.
