  • What If a Quasi-Star Entered Our Solar System?

    4:52

    This rogue star has been traveling the Universe. And now, it's finally entering our Solar System. But this isn't just any regular star. It's known as a quasi-star and is one of the biggest stars in existence. What would happen if this star entered our Solar System? And how would Earth be affected?

  • What If a Magnetar Entered Our Solar System?

    4:20

    This is the most powerful object in the Universe. The biggest spinning magnet to ever exist.
    It's the cosmic equivalent of a great white shark. But it wouldn't eat you. It would just turn all your atoms to dust... If you thought neutron stars were big and scary, well, you haven't heard of their more powerful stellar cousins yet. Like neutron stars, magnetars are leftovers from supernova explosions.

    With the vastness of the Universe, everything in it seems so spread out. But some objects are closer than you might realize. Every now and then, a random interstellar asteroid passes through the Oort cloud, the wall of icy debris at the very edge of our Solar System. But what if a rogue star unceremoniously rampaged right through the Oort cloud?

    Eight planets, hundreds of moons, hundreds of thousands of asteroids, and billions of comets orbiting our Sun make up our Solar System. And not once has a single black hole disturbed our planetary routine.

    But what if it did? Would this uninvited guest swallow up everything on its way through the Solar System? Or would it just slightly disrupt it?

  • What If a Wormhole Formed in Our Solar System?

    3:17

    What would happen if you flew into a wormhole? Would you ever hear back? Where would you end up? Back in time? Another galaxy? Here's what would happen if a wormhole formed in our Solar System.

    You've probably heard of wormholes from Thor, Interstellar, Star Trek, or if you're really old school, Albert Einstein. In 1935, Albert Einstein and physicist Nathan Rosen came up with the idea of bridges in space-time!

  • What If a Magnetar Collided With a Black Hole?

    4:15

    In the center of our galaxy, the Milky Way, there is a supermassive black hole feeding on nearby stars. It's called Sagittarius A*. And if a giant gravitational monster slowly eating the galaxy isn't terrifying enough, there is another cosmic monstrosity lurking around it. Could they, one day, come a little too close and collapse on each other? What would be left of the Milky Way if they did? Would there be even a slight chance that the Earth could get out of that safely?

  • What If Betelgeuse Exploded Right Now?

    5:10

    At about 950 times bigger than our Sun, Betelgeuse is one of the biggest stars in our Universe. But that comes with a price. Just like us, stars have a life expectancy, and Betelgeuse is no different. It’s a ticking time bomb that's ready to go, but we're not sure when. So, what if today was the day Betelgeuse went out with a bang? How would the Earth be affected? And will our Universe ever be the same?

  • Milky Way Bumped Into Another Galaxy But Earth Survived

    10:07

    The Earth is our home and it feels like it has been here forever and will always be there. However, it's not so easy and safe in space, and it looks like the Milky Way is at risk!

    Astronomers believe that in 4.5 billion years, a powerful galactic collision will occur. The Milky Way galaxy, which is the home to our Solar System and the very planet we live on, will collide with the Andromeda Galaxy. The good news is that the collisions, and the potential appearance of a quasar, will have no effect on our planet! What's more, even the quasar's radiation won't manage to disturb the peace of the Solar System.

    SUMMARY:
    -In 2018, the European Space Agency finally released the most detailed map of the Milky Way galaxy.
    -A new galaxy orbiting the Milky Way that was named Antlia 2 was discovered thanks to the powerful telescope.
    -A new study claimed that the very same Antlia 2 is responsible for bizarre ripples disturbing the hydrogen gas in the Milky Way's outer disc.
    -It seems that over time, the Milky Way has absorbed loads of the material Antlia 2 consists of when the two collided about 1 billion years ago.
    -There might be not one, but two galactic collisions; and the first is likely to happen around 2 billion years from now, when the Milky Way collides with the Large Magellanic Cloud.
    -All the constellations, as we know them, will disappear from the sky, but the potential appearance of a quasar, will have no effect on our planet.
    -The chances of several stars colliding during the galaxies' merge are really low because stars are located too far away from each other.

  • What If All Stars Exploded at the Same Time?

    4:09

    For every galaxy that's visible from Earth, there are nine smaller ones that we can't see, even with all the technology we've developed. That's 90% of all space stuff in the observable universe that we're missing out on. We can't even see all the stars in the Milky Way. Our home galaxy is just too cluttered with gas, dust, smaller stars and, well, one supermassive black hole. All that makes it impossible to tell how many stars there really are out there. But whatever that number is, it sure has a lot of zeros in it.

    When Quasars were first discovered the amount of light pouring out of such a tiny dot in space seemed impossible. A hysterical flurry of hypothesizing followed: swarms of neutron stars, alien civilizations harnessing their entire galaxy’s power, bright, fast-moving objects being ejected by our own galaxy’s core. But by the 1980’s we were converging on the most awesome explanation. It goes a little like this: Take a black hole of millions to billions times the mass of the sun. Where from? It turns out every decent-sized galaxy has one at its core. Now drive gas into the galactic core. One way this can happen is when galaxies merge and grow. That gas descends into the waiting black hole’s gravitational well and gains incredible speed on the way. It is swept up in a raging whirlpool around the black hole that we call an accretion disk, where its energy of motion is turned into heat. The heat-glow of the accretion disk is so bright that we can see quasars to the ends of the universe.

You can see it from Earth because we live on its very outskirts, far away from all the fun stuff happening in its center. What would it be like to reside in its galactic downtown? Would we still have our familiar Sun? What would our night sky look like? Would we get sucked into a black hole?

  • What If Our Universe Collided With Another One?

    5:21

    This pretzel-shaped collection of galaxies is our Universe. And it's about to collide with another universe. It might be fascinating to watch, but we should probably be worried about what's going to happen when they crash. How would it change the physics of our Universe? Is there any chance that we would survive? What would the collision look like from Earth? And has it ever happened before?

  • What If Two Black Holes Collided?

    5:08

    Black holes are the gravitational monsters of the Universe. They are so powerful that nothing, even light, can escape their grasp. One black hole is bad enough. But if you took two black holes and smashed them into each other, they'd be capable of changing the shape of space itself. How epic would that explosion be? And could it somehow reach the Earth?

    Horizon Radiation


    The Sun is slowly burning through its fuel. Hydrogen is fused into helium in the Sun’s core, producing energy that keeps it shining, and keeping the Earth warm and hospitable to life. But that fuel WILL run out, after which the Sun will swell into a red giant and flash-fry the Earth. But in fact that frying – well, slow-roasting – will begin much earlier. See, the Sun is getting brighter even now. This has complex, and for the most part terrible implications for life. The end of the world will come sooner than you think.

    Bialy & Loeb (2018)


    Micheli et al. (2018)


    Last year a visitor came to our inner solar system. To us it looked like a faint spot of light, moving quickly relative to the fixed stars. We’d seen similar things countless times before – lonely rocks, remnants from the formation of our solar system, drifting on their endless orbits around the sun and faintly glimmering with its reflected light. Nothing unusual about such asteroids and comets, but what made this object special was its trajectory. It was not in orbit around the Sun at all. Rather, it appeared to have fallen in from interstellar space, and was on its way back out again. The object is 1I/2017 U1, better known as ‘Oumuamua. It’s the first chunk of interstellar space debris we’ve ever spotted passing through our solar system. It caused a justifiable stir at the time. Hell, WE even did an episode on it.

  • Alex Filippenko: Astronomer To The Stars

    1:37:31

    Despite all the media attention given to black holes, dark matter and dark energy, astronomy is actually all about the light—the decillions of photons careening around the universe.

    Join us virtually for a conversation with Alex Filippenko, a Berkeley astrophysicist who works on deciphering, from all that photonic information live-streaming to Earth, what is really going on out there. Filippenko will also share some of the spectacular images from deep space that our technology has been able to construct from the clues left behind by billions of those wandering photons.

  • Thats Whats Happening Above Your Head Right Now

    1:36:03

    Hey there! Join our conversation about space! The universe is enormous and full of secrets and there are still millions of things to be discovered. Imagine neutron stars so fast they devour everything in their path, clouds that smell of fruits, an enormous gathering of galaxies...and Louis Armstrong music in space? Outer space is amazing by its sheer size, the trillions of massive objects it accommodates, and the many secrets it holds, some of which you’re about to find out.

    For example, one of the most exciting questions is if there are other planets people can live on? Actually, over 30 of the planets in our Milky Way galaxy are very likely to be habitable to human being. Scientific teams have been hard at work trying to discover habitable planets. And we're gonna tell about that today!

    Also, you're gonna find out some little-known earthly facts. Think nothing can surprise you at this point? You’ll be amazed when you find out how much you have yet to learn about our home planet! Did you know, for example, that Earth was originally a different color? Or that the Moon isn’t Earth’s only satellite? So, guys, watch our video to discover how a single teaspoon can weigh a billion tons, and how our galaxy is heading on a deadly collision, along with other incredible facts!

  • Comets: Visitors from the Frozen Edge of the Solar System - Professor Carolin Crawford

    53:51

    Millions of dirty icebergs orbit around the Sun in a huge cloud of debris almost a light-year in radius. These are all pristine relics of our primordial Solar nebula. Only when one tumbles towards the inner Solar system does it heat up to develop into the spectacular apparition known as a comet.

    The transcript and downloadable versions of the lecture are available from the Gresham College website:

    Gresham College has been giving free public lectures since 1597. This tradition continues today with all of our five or so public lectures a week being made available for free download from our website. There are currently over 1,500 lectures free to access or download from the website.
