Save 40% off the Vantage plan through my link for unlimited access this month only. Black holes burp. A lot. And we think these burps have a huge impact on how the Universe has evolved. If there’s a strong magnetic field around the black hole, that burp material can get funnelled up and away into a really tight jet. And these jets end up being way bigger than the entire galaxy that we find a black hole in. For example, this galaxy Hercules A is a really famous example of this, with jets than span almost a million light years. But this month, a team of astronomers, Oei and collaborators, reported finding the longest black hole jet ever seen at 23 million light years long. It is HUGE. And while it’s very cool to find the longest or biggest of something out there in the universe, this discovery also has big implications for how the Universe has evolved and galaxies grow. So in this video we’re going to chat about, 1) how Oei and collaborators found this giant black hole jet, Porphyrion, 2) the properties of Porphyrion, and how it compares to all the other black hole jets they found, and 3) what effect black hole jets of this size could have on the universe around them.

Save 40% off the Vantage plan through my link for unlimited access this month only. | Where are we likely to find life in our Solar System outside of Earth? Mars, Venus, or maybe even Europa? A moon of Jupiter. The more we study the moons of the gas giants, the more they surprise us, with Saturn’s moons Enceladus and Titan turning out to look like pretty good candidates for finding life. Enceladus even has plumes, big geysers of water, coming from its poles suggesting there’s a liquid water ocean beneath its icy crust. The Cassini mission even flew through those plumes and found that water even contains the building blocks for life. And there’s a lot of moons that also have this icy crust that are thought to be hiding a liquid water ocean underneath them. One of those is in orbit around Europa, which is why NASA have decided to send the Europa Clipper mission to investigate which launches very soon in October 2024, but won’t arrive at the Jupiter system until 2030. And it’s main mission is to work out if Europa is habitable to life or not?

http://drbecky.uk.com rebeccasmethurst.co.ukIs AEROCAPTURE how well eventually send a mission to Uranus or Neptune?Dr. Becky2024-09-10 | Look I want a mission to go to Uranus and Neptune as much as the next person, but it’s annoyingly not as simple as just yeeting a spacecraft out to the edge of the solar system, because otherwise it’ll just fly straight past the planets. That’s what Voayger 2 did in the 80s, the first and only probe to visit Uranus and Neptune. If you want to actually stop and orbit one of the ice giants to study it in the way Cassini did around Saturn, or Juno is doing around Jupiter, you’ve got to break and slow down somehow. And that’s the hard part.
For example, when Juno arrived at Jupiter in 2016, it was traveling at about 165,000 miles per hour. So to slow down, Juno turned around and burnt a load of fuel to fire its engine against its direction of travel, slowing it down enough to be captured by Jupiter’s gravity. So you might be thinking, well why don’t we just do that when we send a craft to Uranus and Neptune then? But the problem is that to get a spacecraft that far out in the Solar System you need a lot of fuel, and you need to accelerate it up to a huge speed, which means you need even more fuel to then slow it down when it gets to the ice giants. And the more fuel you need to break, the heavier your spacecraft gets, and the more fuel you need to launch it until the amount of fuel you need just becomes unfeasible. Not to mention that fuel is expensive.
So NASA and ESA are investigating something known as aerocapture when a spacecraft uses a planet's atmosphere to slow down. Instead of using fuel, it dips into the thick atmosphere, creating drag as all those air molecules hit the spacecraft and slow it down. Think of it like skimming a rock across a pond, but in space! But this is fraught with danger, you’ve got to hit the atmosphere at a precise angle. Too steep, and the craft burns up. Too shallow, and it bounces off back into space and doesn’t enter into orbit. If we could do this it would reduce the amount of fuel needed, allowing for more scientific instruments on the craft instead, and make a mission cheaper so that they’re more likely to be funded. So fingers crossed!

How do we know that the Earth is around 150 million km from the Sun? Sure today we can use radar to bounce light back and forth between objects to work out how far away they are, but before that, it’s not like people could break out a giant tape measure to do this, scientists had to get clever about it, they had to use trigonometry to get at the very first measurement of the distance of the Earth from the Sun in the early 1700s using a transit of Venus, and in doing so unlock the entire scale of the Solar System. So this video, is for anyone that’s ever said that trigonometry is not useful, because it most definitely is! If you’re an astronomer anyway...

http://drbecky.uk.com rebeccasmethurst.co.ukRenovating my new office PART 5 - NEW LIGHTS!Dr. Becky2024-08-30 | There is something I’ve been meaning to do in my new office for ages and that’s install some lights on my shelves. Because the background of my videos since I moved house have been looking a bit, well dark. Basically, we need what’s known in the biz as a backlight, or a hair light, placed behind someone to help separate them from the background. It was such a simple job installing them, but because I had to take everything off the shelves to do it, I kept putting it off, but we’re all good now, so the background of my videos will now look like this from now on. I like the light blue colour best, but let me know which colour you like in the comments. Next up is to get some more fun stuff for my shelves, because at the minute, it’s just Sam’s car LEGO on here, and apart from the Space Shuttle, I think we need some more space-y things on here!

Save 40% off the Vantage plan through my link for unlimited access this month only. - I never ever get tired of seeing images we’ve taken of other worlds - other planets orbiting distant stars in our galaxy the Milky Way. This is very difficult to do though, because the star is so bright, and the planet reflecting the starlight so dim in comparison, the contrast between them is huge. We actually have to fully block the light from the star by putting a mask over the centre of the telescope, called a chronograph. JWST has one of these chronographs too, and this month we saw the latest direct image it had taken this time of the planet Epsilon Indi Ab which was published in this research paper by Matthews and collaborators. Now this image was a big deal for a few reasons, first it was actually a discovery image of the planet, it’s one of the coldest and oldest exoplanets to ever be directly imaged, AND is the closest planet to Earth that’s more massive than Jupiter at around 12 light years away. So exciting for a number of reasons and in this video we’re going to dive into why it’s exciting and what we can learn from it.

👩🏽💻 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.
http://drbecky.uk.com rebeccasmethurst.co.ukThe Moon occults Saturn on Wednesday 21st August 2024Dr. Becky2024-08-19 | In the early morning of the 21st august the full moon will fully occult Saturn - occult comes from a latin word which means “to hide” something - which is exactly what happens here the moon as it moves along its orbit will pass in front of Saturn and hide it for a while. Now because of the angles involved for the moon to fully block Saturn from our perspective this is only visible in certain parts of the world - from South America, across northern Africa, and Europe - there's a link below that gives the time of the occultation - but the fun thing to do is to watch for a long period of time with binoculars or a telescope and see Saturn disappear behind the moon and then reappear again - in the UK that occurs around half 4 in the morning, again depending on your exact location and reappears again around 45 minutes later. If you want to check exact timings for your location I’d recommend using an app like Stellarium, I like the desktop version for things like this, and I’ll zoom in on Saturn and the moon and just click forward on the time to see what time Saturn will disappear and reappear.

http://drbecky.uk.com rebeccasmethurst.co.ukHas JWST solved the crisis in cosmology? Or made it WORSE? #shortsDr. Becky2024-08-13 | It’s finally here! the research paper we have all been waiting for - JWST’s look at the crisis in cosmology, aka the Hubble Tension where we’re getting different answers for the expansion rate of the universe depending on what method we’re using. If you remember i did a video on this when they presents work on the conference circuit back in spring, but we didn’t have any details. Well now we do, this new paper from Freedman and collaborators appeared online today, although its still not gone through peer review, and it has essentially said that they’ve now used JWST instead of the hubble space telescope to do this, there’s no longer a problem, the values for the rate of expansion of the universe with these different methods don’t disagree anymore, at least not within the errors on the measurement. Question I still have is what changed between hubble and JWST data? So I’m going to dive into reading this research paper this week, absorb all the details, and report back in my next Night Sky News episode for August which is coming out next Thursday 22nd, so make sure you’re subscribed so you don’t miss out! #cosmology #JWST #astrophysics

http://drbecky.uk.comMars + Jupiter Conjunction 15th August 2024 #shortsDr. Becky2024-08-09 | Mars and Jupiter will be around in the morning sky all month rising ever earlier as time marches on and also appearing to getting closer together from our perspective as each planet moves along its orbit. So that by early morning on Thursday 15th of August they’ve reached what’s known as conjunction, they’re closest approach on the sky - where they’ll be less than the width of the full moon away from each other - at their closest they’ll be about 0.3 degrees apart. about the width of your little finger at arms length, meaning they can both fit in the field of view of a typical amateur telescope. Now wherever you are in the world you should be able to see them getting closer together all throughout the month, but the closest approach happens on Wednesday 14th august at 16:52 GMT, so if in your time zone that’s early morning, so New Zealand and Polynesia you’ll see the exact time of closest approach, but the rest of us will still see them very close indeed - let's hope for clear skies! #astronomy #stargazingHow ASTROPHYSICISTS use ARTIFICIAL INTELLIGENCEDr. Becky2024-08-01 | AD - Thanks to Skillshare for sponsoring this video! The first 500 people to use my link will get a 1-month free trial of Skillshare: https://skl.sh/drbecky07241 | AI, or artificial intelligence, feels like a buzz word you just can’t escape from these days. It is everywhere. And astrophysics is no exception with a steady increase in the number of research papers published either using or mentioning AI tools such as machine learning and deep learning. So in this video let's chat about what actually is AI - what can it do, what can it not do, because there’s a lot of misinformation out there, before we then chat about 4 ways that us astrophysicists use AI: i) classification of data, ii) finding weird things (anomaly detection), iii) inference of data, and iv) emulation of simulations. This is by no means an exhaustive list, I’m sure many of my colleagues are also using AI in other ways for the research, not to mention using well known tools like GitHub’s copilot to help them write code, or chatGPT to help them with inspiration when trying to summarise research papers or grant proposals into abstracts. AI has perhaps changed the way we work as astrophysicists, but has not yet changed astrophysics itself. The key word there though being *yet*, because with the pace of advancement of AI that we’re seeing, who knows what the next decade could bring!

The new Galaxy Zoo: Euclid project has just launched! If you’re not familiar with galaxy zoo it’s a website where us astronomers ask the public for help classifying the shapes of galaxies in huge datasets taken by survey telescopes. My PhD was made possible thanks to people classifying on galaxy zoo, and I’ve been part of the science team for over 10 years now, so I’m so excited that I get to announce this for you all: that images from the recently launched Euclid space telescope are now up on the site ready to be classified - this data hasn’t been released publicly yet so you will be the very first people to ever see these images from Euclid, and not only that be the very first humans in the Universe to see these galaxies. If you want to know more about Euclid I’ve made a whole video about it before, but essentially it’s goal is to produce images like the Hubble Ultra Deep field but for 2/3 of the entire night sky - essentially the bits where our own Milky Way galaxy isn’t in the way. That’s a lot of data, and labelling that is very difficult. So at Galaxy Zoo, we do have an AI deep learning algorithm called ZooBot sifting through the images first, labelling the easy ones that we already have a lot of examples of from previous surveys, and then the ones the AI is not confident about it shows to users on Galaxy Zoo to get their classifications which help teach the algorithm even more. So this is machines and humans working together in the most efficient way. Your classifications will help us on the Galaxy Zoo and Euclid science teams to answer questions like how has the shape of galaxies changed over time, what are the processes that transform the shape of galaxies, how does the balance of normal to dark matter affect the shape, and so much more. We’ve written a blog post over on the Galaxy Zoo website if you’d like to know more about the project and the link to the Galaxy Zoo: Euclid website is in the video description below - happy classifying!Delays to the Europa Clipper launch to Jupiters icy (potentially habitable) moon? NSN July 24 BONUSDr. Becky2024-07-26 | There’s been a lot of doubt cast this month about NASA’s Europa Clipper mission which is planned for a launch in October on one of SpaceX’s falcon heavy rockets. Europa clipper is set to explore Jupiter’s icy moon Europa with a number of fly-bys. And what’s so special about Europa? Well the Galileo mission in the early 2000s found evidence that there could be a liquid ocean under Europa’s icy crust layer. So the idea is Europa Clipper will investigate its habitability and study the surface to try and find a suitable place for the Europa lander to touch down which is set to launch a few years later in 2027. Now as we get closer to the launch date, things are starting to get a bit nail biter because this month NASA announced that the team’s engineers have been investigating a problem with the transistors on board the spacecraft - these are essentially switches that can control the flow of electricity on the craft - and they found that they were failing at lower radiation doses than they were rated for. That’s a big deal because the region around Jupiter’s is the most radiation intense in the solar system because of Jupiter’s strong magnetic field that’s 20,000 times stronger than Earth’s, which traps all the high energy particles from the Sun. Europa clipper will have to exist in that environment and it can’t if the transistors fail. So the team at NASA are working with the manufacturers to work out if all of the transistors are affected and to what degree. There’s a report due at the end of July so let’s hope it’s good news because that October launch window for Europa clipper is only 21 days. SO we can only afford a 3 week delay 🤞

Using an X-ray spectrum of the black hole MAXI J1820+070 Mummery and collaborators were able to prove that the region around a black hole existed as Einstein predicted in his theory of General Relativity. Even more exciting still, is that this could be a new method for measuring the spin of a black hole!

👩🏽💻 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).

http://drbecky.uk.com rebeccasmethurst.co.ukPainting my new filming space and office! 🖥️ #shortsDr. Becky2024-03-25 | It's time to paint my new filming space, because this two-tone sad pink does not scream "we love astrophysics here!" to me at all. What do you think of the colour I went with in the end? I'm really excited to finally get some furniture soon for this space and we can start building up the backdrop for my videos.

http://drbecky.uk.com rebeccasmethurst.co.ukAn astrophysicist reacts to 3 Body Problem #shortsDr. Becky2024-03-22 | I got invited to the London premier of Netflix's new sci-fi show 3 Body Problem (created by the team from Game of Thrones and based on the books by Liu Cixin) and you know I can't turn off my astrophysics brain while I watch sci-fi, so as usual I had many thoughts while watching the first episode. So here's my initial reaction, from diffraction spikes on stars when the Universe is winking, to whether physicists would be happy or sad if theory suddenly stopped agreeing with experiments, to passing off the Super Kamiokande experiment in Japan as a particle accelerator in Oxford! #3bodyproblem #netflix #astrophysicist @Netflix

http://drbecky.uk.com rebeccasmethurst.co.ukMy new filming space and office 🥳 #shortsDr. Becky2024-03-16 | My new filming and office space is here 🥳 and the first video has been filmed in it! I love interior design so I’ve been having fun planning all the rooms in our new house. I have a vision for how I want to decorate this space - I’m thinking a space-y blue paint colour as my filming backdrop, with some cool shelves that I can display all my favourite things on, maybe even light them with some LEDs! What would you do with this space? Let me know down in the comments below! Also, did anyone else hear how American my voice went when I said closet? I should’ve just called it a cupboard 😅
