👩🏽💻 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.

Hello and welcome to this episode of Night Sky News for September 2024! This is the show where we chat about what you should look out for in the night sky in the next month, and what’s been happening in space news in the past month. In this episode we’re chatting about SO many things, including which planets you can spot in the night sky, the annular solar eclipse visible across South American, how to look out for C/2023 A3 (Tsuchinshan–ATLAS) if it becomes bright enough as it gets closer to the Sun, plus the successful lunar-earth flyby of the JUICE spacecraft on its way to Jupiter, the new hypothesis to explain the famous unexplained Wow! signal (which sadly isn't aliens), and a new explanation for JWST’s “impossible” over-massive galaxies!

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!

👩🏽💻 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.

Read the Galaxy Zoo blog announcing the project here - blog.galaxyzoo.org/2024/08/01/announcing-the-galaxy-zoo-euclid-project
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!

In this month’s Night Sky News episode we’re chatting about how to spot the conjunction of Mars & Jupiter, the Moon occult Saturn, and the Pleiades meteor shower. Plus in space news we’ll be chatting about the intermediate mass black hole that’s been found in our galaxy, right in the mass gap where we’ve never found a black hole of that mass before, ESA’s recent Ariane 6 launch, JWST’s look at the famous Penguin galaxy, plus the asteroid Chiron turning into a comet.

matter 5 to 1, we still don’t know what it’s made of because we haven’t *directly* detected it. BUT what if we could use Jupiter to
detect dark matter? That’s what this paper published by Blanco & Leane this month tried to do by detecting trihydrogen cation, or H3+ and it definitely set some heads turning...

👩🏽💻 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.

There's a strange, unexplained feature of the Cosmic Microwave Background which seems to be aligned with the Solar System, and we don't why. Is it real or just a coincidence?

👩🏽💻 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).
