Wait, has JWST SOLVED the crisis in cosmology?! #shorts #astronomy #science Dr. Becky 2024-04-08 | At a meeting of the American Physical Society last Saturday there was a *very* interesting talk from Wendy Freedman - the lead researcher of a group using JWST to investigate the "crisis in cosmology" aka the Hubble Tension. This is one of the biggest problems in modern astrophysics, where our two main methods for calculating the expansion rate of the Universe don't agree. But now, this collaboration are claiming that with their JWST data, the two values DO agree and they've solved the Hubble Tension. That's despite the fact that we've heard from one JWST research group already who claimed that their JWST data made the crisis in cosmology WORSE. So what is going on?!

And this month there’s a paper been published by Maiolino and collaborators claiming to have found just that, around a galaxy known as GN-z11 (the previous record holder of most distant galaxy known). But claims of evidence of the first stars in the universe, aka population III stars, are not be made lightly. So in this video we’re going to chat about (1) what are population III stars?

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 😅

Either with constructive or deconstructive interference, just like water waves, sound waves, or light waves? They're waves yes, but they're not mechanical waves or electromagnetic waves like sound or light, so do they still behave like a wave?Thanks to the detections made by LIGO and VIRGO gravitational wave detectors of neutron star mergers we now have some idea, but can we observe this in the future in black hole mergers?

TWO Earth-like planets found in the HABITABLE ZONE (just 6% bigger than Earth!) Dr. Becky 2024-03-07 | The holy grail of exoplanets research is to find an Earth-like planet in the habitable zone around its star (where it's not too hot and not too cold for life to exist) and then study its atmosphere with the James Webb Space Telescope to determine if life is present there. But to do that, we have to find these planets first. This is where the TESS mission comes in; this month a research paper was published claiming to have found TWO possible Earth-like planets in the habitable zone. The hope is that we can use JWST to study at least one of them. Dransfield et al.

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.

Ingenuity helicopter on Mars damages rotor blade, and is no longer able to fly #shorts Dr. Becky 2024-01-26 | Sadly the Ingenuity helicopter (aka Ginny) on Mars has damaged its rotor blade and can no longer fly. Originally designed to be a proof of concept and undergo just 5 flights on Mars, it’s now completed 72 in nearly 3 years and flown 14 times further than anyone ever planned, helping the Perseverance rover (aka Percy) pick out routes across the Martian surface. Here’s to the next helicopter mission in the Solar System: Dragonfly, which will launch in 2028 to visit Saturn’s largest moon Titan. #astronomy #nasa #perseverance

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...** REFERENCES **Irwin et al.

No, JWST has not discovered aliens... #shorts #aliens #jwst Dr. Becky 2024-01-17 | Just clarifying some comments I made in an earlier video that got picked up and twisted by UFO enthusiasts and then again in the media! Remember, any future claims of a potential biosignature detection of a molecule in an exoplanet atmosphere means it *could* be due to life but also could be unknown chemistry.

JWST & the BIG DEBATE on GN-z11: one of the most distant galaxies in the Universe Dr. Becky 2024-01-11 | To try everything Brilliant has to offer—free—for a full 30 days, visit brilliant.org/drbecky - the first 200 of you will get 20% off Brilliant's annual premium subscription.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. Maiolino et al. (2023) - arxiv.org/pdf/2305.12492.pdf Cameron et al.

An ULTRA-HIGH energy cosmic ray hit Earth | Night Sky News Dec 2023 Dr. Becky 2023-12-21 | In this month's Night Sky News episode we're chatting about the Amaterasu cosmic ray particle that hit the Earth with 813 billion times more energy than a typical cosmic ray particle! Plus there's three new exoplanet research articles released this past month from the first planet forming system spotted outside the Milky Way in the Large Magellanic Cloud, to a "perfect" 6 planet system all in resonance with each other, and a new paper claiming we sadly don't have any evidence for exomoons. And of course there's all the details on how you can spot the Quadrantids meteor shower in January, and the International Space Station in December.

Searching for aliens might sound like something from sci-fi, but there are legitimate scientific searches for signs of life beyond Earth in the Universe. Either through biosignatures in planet atmospheres, or for technosignatures of advanced civilisations. The largest ever search for technosignatures is being conducted by the Breakthrough Listen project, and this month they published their latest research searching for extra-galactic signals from beyond our Milky Way.

The Geminids Meteor Shower peaks on December 13th 2023 (spot them at the weekend too!) #shorts Dr. Becky 2023-12-08 | The Geminids Meteor Shower is nature’s own Christmas lights show! Every year it peaks in mid-December (We’d 13th December in 2023) and this year especially is set to be spectacular with no moonlight to spoil the show. If you can get somewhere dark you could see up to 120 meteors per hour! That’s 2 shooting stars per minute. These will still be visible on the nights around the 13th, so if you have some time this weekend or next to head outside and stargaze: do it!

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).

Purple splotches in new Euclid space telescope images: real objects or ghosts? #shorts #astronomy Dr. Becky 2023-12-01 | What are the weird purple splotches in the new Euclid space telescope images? They’re sadly not an undiscovered space object but a “ghost” in the image caused by re-reflection of light inside the telescope back onto the detector. It’s most noticeable when there’s a very bright object like a nearby star and it affects blue light more.
New study just made the crisis in cosmology WORSE Dr. Becky 2023-11-30 | Go to brilliant.org/drbecky to get a 30-day free trial and the first 200 people will get 20% off their annual subscription! The so called “crisis in cosmology” (or Hubble tension) is the biggest problem in astrophysics right now, with two main methods for calculating the expansion rate of the Universe, which completely disagree with eac†teemh other. This month a new study came out pointing out that the Milky Way is found in the Laniakea supercluster of galaxies, a very dense part of the Universe.

JWST finds most distant supermassive black hole known (and its WAY BIGGER than should be possible) Dr. Becky 2023-11-23 | Go to https://ground.news/drbecky to get access to reliable information all in one place. Subscribe through my link to get 40% off unlimited access during their biggest sale of the year. Sale ends November 30.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 🤯#shorts Dr. Becky 2023-11-07 | Check out the @europeanspaceagency website to take a look at the images yourself! https://www.esa.int/Science_Exploration/Space_Science/Euclid/Euclid_s_first_images_the_dazzling_edge_of_darkness 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.
What do Jupiter & Saturn look like through a telescope? | Vlog Maldives Soneva Fushi October 2023 Dr. Becky 2023-11-05 | In October of 2023 I travelled to Soneva Fushi in the Maldives where they have an amateur observatory with a 14" telescope. While I was there I wanted to try and capture what Jupiter and Saturn look like to your eyes when you look down the telescope. I managed to attach my camera to the back of the telescope and was amazed at what I captured. I was invited to Soneva Fushi @discoversoneva to give stargazing tours to guests at the observatory in the evenings and had a wonderful trip (the trip was gifted in exchange for the stargazing evenings, I was not required to make this video but wanted to anyway!) - check out the resort here: soneva.com/resorts/soneva-fushi #astrotourism #astrophotography #maldives The T2 to E-mount adaptor I used: amazon.co.uk/dp/B092MMVCTD?psc=1&ref=ppx_yo2ov_dt_b_product_detailsMy camera is a Sony ⍺ 7 IV: electronics.sony.com/imaging/interchangeable-lens-cameras/all-interchangeable-lens-cameras/p/ilce7m4-b00:00 - Introduction01:17 - The telescope at Soneva Fushi02:45 - How I captured this with my camera and a telescope04:31 - Jupiter07:08 - Saturn 09:32 - OutroVideo filmed on a Sony ⍺7 IV & an iPhone 13 Pro---📚 My new book, "A Brief History of Black Holes", out NOW in hardback, e-book and audiobook (which I narrated myself!): http://lnk.to/DrBecky---📚 "The Year In Space" celebrating all things space in 2022 from me and the rest of the Supermassive Podcast team: geni.us/jNcrw ---👕 My new merch, including JWST designs, are available here (with worldwide shipping!): dr-becky.teemill.com---🎧 Royal Astronomical Society Podcast that I co-host: podfollow.com/supermassive ---🔔 Don't forget to subscribe and click the little bell icon to be notified when I post a new video!---👩🏽💻 I'm Dr. Becky Smethurst, an astrophysicist at the University of Oxford (Christ Church).

JWST investigates failed supernova - did it form a black hole? Dr. Becky 2023-10-19 | Back in 2009 a star flared in brightness and then completely disappeared. The best explanation we had at the time was that the star had skipped supernova entirely and collapsed straight down into a black hole. But now the James Webb Space Telescope has taken a look and found something there in infrared light that doesn't seem to have changed brightness at all. So what else could it be?

Top tips for viewing the Moon through a telescope #shorts #AD Dr. Becky 2023-10-06 | #AD The best cabins to escape to come with their own telescopes! 🔭 recently I got to stay with @Canopyandstars at the Ursabear cabin on the edge of Exmoor National Park (a designated dark sky site) in Devon. It was set up perfectly for stargazing (like all the Canopy & Stars cabins are) and I had great fun observing the quarter Moon 🌗 the best time to observe the Moon with a telescope is when it’s not full, and the shadow line known as the “terminator” throws up lots of detail on all the craters.

How MASSIVE can a STAR get? Dr. Becky 2023-10-05 | Go to brilliant.org/drbecky to get a 30-day free trial and the first 200 people will get 20% off their annual subscription! We know there's a limit to how small a star can be, but is there a limit to how BIG stars can get? Is there some aspect of Physics that limits how big they can grow, or do big stars just get rarer and rarer so we're less likely to see them? The biggest star we've ever found is R136a1 at around 200 times heavier than the Sun, and that is very challenging for our models of star formation to explain...My previous video on the lower limit to the mass of stars - youtube.com/watch?v=-l5_RZvZ5VESalpeter (1955; first analysis of the IMF) - https://articles.adsabs.harvard.edu/pdf/1955ApJ...121..161SHopkins (2018; review on the IMF) - arxiv.org/abs/1807.09949Larson & Starrfield (1971; the limit from models of star formation) - https://articles.adsabs.harvard.edu/pdf/1971A%26A....13..190LNakano (1989; increasing the limit with models of star formation) - https://articles.adsabs.harvard.edu/pdf/1989ApJ...345..464NJijina & Adams (1996; increasing the limit with models of star formation) - https://articles.adsabs.harvard.edu/pdf/1996ApJ...462..874JFeast, Thackery & Wesselink (1960; catalogue of stars in the Magellanic Clouds) - academic.oup.com/mnras/article/121/4/337/2602312Ebbets & Conti (1982; R136a1 is 2000 times the mass of the Sun?) - Bestenlehner et al.

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.comrebeccasmethurst.co.uk
I guessed who would win the Nobel Prize in Physics 2023! #shorts Dr. Becky 2023-10-03 | The Nobel Prize in Physics for 2023 was awarded to Anne L’Huillier, Ferenc Krausz & Pierre Agostini for their work on attosecond Physics to observe electrons moving so you can watch chemical reactions in real time! It’s notoriously difficult to predict who will win the Nobel Prize but I called it 3 days earlier 😂 I am incredibly smug today.👩🏽💻 I’m Dr. Becky Smethurst, an astrophysicist at the University of Oxford (Christ Church).
