00:00Just when you think space couldn't get any more weird, uh, weirder?

00:05Hey, check my grammar.

00:06The universe throws a curveball in the form of a giant glowing bubble that's too perfect to be real.

00:13Astronomers have spotted something strange drifting through our galaxy.

00:17And it's not a rogue planet, which is a space body the size of a planet that doesn't orbit any star.

00:23It's not a star itself, either.

00:25It's not even your average supernova remnant.

00:27It's a perfectly round sphere, and scientists are stunned.

00:32Astronomers were going through data from a super-powerful radio telescope

00:36when they spotted something that looked like a perfect round bubble.

00:40At first, they thought it was the leftovers from a massive star explosion called a supernova.

00:45But the weird part was that the object was too perfect.

00:50Normally, such explosions leave behind messy, uneven clouds.

00:53And the newly discovered one looked like someone had drawn it with a compass.

00:58The scientists named the space bubble Teleos, which means perfect in ancient Greek.

01:04They've already looked at all the possible explanations, but none of them really make sense yet.

01:09This strange space body was discovered thanks to a telescope in Australia called ASCAP.

01:16It's been scanning the sky and finding all kinds of weird circular objects.

01:20This research was part of a project called the Evolutionary Map of the Universe.

01:25Some of the faraway circles, known as ORCs, which is short for odd radio circles, have already puzzled scientists.

01:32But this one is different, because it's inside our own galaxy.

01:37At the same time, even though Teleos is technically closer to us, scientists can't quite figure out how close it is.

01:44And that's making it harder to understand where it came from or how it formed.

01:50The researchers have taken an even closer look at this strange space bubble and found something super odd.

01:56It only gives off a very faint glow, and only in radio waves, not in visible light or x-rays.

02:03Based on that glow, they've figured it's most likely the leftover shell of a massive star explosion called a type La Supernova,

02:12one of the brightest and most powerful kinds of explosions in the Universe.

02:16This kind of explosion happens like this.

02:18A super-dense dead star called a White Dwarf starts stealing material from a nearby star.

02:24It keeps sucking in stuff until it just can't handle the weight anymore, then it blows up in a huge burst of energy.

02:32Now that part makes sense.

02:34But figuring out how far away is this thing?

02:37Strangely, it's not so easy.

02:39Scientists have run the numbers and ended up with two possible distance for Teleos.

02:44Either it's around 7,175 light-years away, or it's much farther, about 25,114 light-years away.

02:54Eh, give or take.

02:55Depending on which distance is right, the size of the bubble could be vastly different.

03:00If it's closer, then it's about 46 light-years wide.

03:04That would make it a pretty young supernova remnant, maybe less than 1,000 years old.

03:09But if it's farther away, then it's a giant 157 light-years across, which could be more than 10,000 years old.

03:18So, which one is it?

03:20That's where things get tricky.

03:22Scientists have models that tell us how these supernova leftovers should behave.

03:27And one of the most important things they expect to see is X-rays.

03:32But you might remember that Teleos doesn't show any.

03:35Not a single X-ray in sight.

03:37That's the big mystery.

03:39How can something that should be glowing with X-rays be totally silent?

03:43It just doesn't add up and leaves the scientists very puzzled.

03:47Another idea the scientists are considering is that Teleos might not be a regular supernova remnant at all.

03:55Instead, it might be the leftovers from a rarer kind of explosion called a type lax supernova.

04:02And this one?

04:02It's extra weird.

04:04In a normal type la supernova, the white dwarf star blows itself to bits.

04:09But in a type lax supernova, it doesn't get totally destroyed.

04:14It kind of survives, turning into a zombie star.

04:17It's damaged, but it's still around.

04:20This would actually explain a lot about how Teleos looks and glows.

04:25But in this case, it would have to be much closer to us, only about 3,262 light-years away.

04:32That would also make it a lot smaller, about 11 light-years wide.

04:36The coolest thing here is that there's actually a star at that distance that could be the zombie star that caused all this.

04:43But, and it's a big but, like I have,

04:46when scientists use other ways to try and measure how far away Teleos is,

04:51none of them agree that it could be this close.

04:54So, sadly, this theory hits a bit of a wall.

04:58Then there's another strange thing.

05:01Teleos' nearly perfect spherical shape.

05:04That's not normal.

05:05Usually, supernova explosions are kind of messy and uneven.

05:09The blast might push into clouds of space dust or gas,

05:13or parts of the explosion might move faster than others.

05:16Eventually, the shell that forms gets all lumpy or starts to break apart.

05:21But in this case, the object is almost perfectly round, like a balloon.

05:26And that's super rare.

05:27The only way something could stay this neat and round is if it exploded in a very empty part of space

05:34and expanded smoothly in all directions.

05:37That's actually not impossible, just really, really rare.

05:41Now, considering its unique, probably unnatural shape,

05:45could Teleos be an artificial object?

05:48Could it be a Dyson sphere?

05:51That's a hypothetical megastructure that could completely surround a star and harvest all of its energy.

05:57At first, this idea was supposed to explain how we might detect intelligent extraterrestrial life

06:03by spotting the energy they use rather than waiting for them to send us a message.

06:07You see, here on Earth, we only receive a tiny bit of the Sun's energy.

06:13Meanwhile, a whopping 386 billion billion megawatts are shooting out into space in all directions.

06:20Not to waste such a giant amount of energy.

06:23A civilization could build a Dyson sphere, or, more realistically, a Dyson swarm,

06:29loads of solar panels orbiting the star.

06:32It would help them capture every bit of that power to run their planet, technology, AI systems,

06:38and maybe even space travel across galaxies.

06:42To understand just how advanced a Dyson sphere-building species would have to be,

06:47scientists use the Kardashev scale.

06:49It ranks civilizations by how much energy they can use.

06:53Type 1 can use all the energy available on their home planet.

06:57Spoiler, we're not even there yet.

06:59Type 2 can harness all the energy from their star.

07:03That's the Dyson sphere level.

07:05Type 3 can use energy from an entire galaxy.

07:08Think Dyson spheres around every star and even extracting energy from black holes.

07:13Right now, Earth's civilization ranks about type 0.7449, give or take.

07:19That means that we haven't even maxed out the energy available to us on Earth,

07:24including fossil fuels, renewables, and nuclear power.

07:27We're still taking baby steps on this cosmic scale.

07:31Anyway, the problem with the theory that our perfectly shaped object could be a Dyson sphere

07:36is that this example of super-advanced technology would give off heat.

07:41In other words, there would be thermal infrared radiation,

07:44and the object would be unusually bright in the infrared.

07:48This could be a sign that something artificial is absorbing the star's energy

07:52and re-emitting it as heat.

07:54But the scientists have found no heat signatures or anything like that when observing teleos.

08:00So, do we have the final answer?

08:02Not yet.

08:04The scientists have looked at all the existing clues.

08:07How bright the thing is, how big it looks, and how far it might be.

08:11And none of the possibilities are totally perfect.

08:14Each idea has a problem, especially the fact that we're not observing any x-rays,

08:20which should be there according to the usual rules.

08:23They still think that regular type L.A. supernova idea is the best bet for now,

08:28but they're not 100% sure.

08:31There's just not enough proof to say for certain.

08:34So, the mystery continues.

08:37The team says we'll need more powerful and detailed observations

08:40to really figure out what happened here.

08:42But, in any case, if something like teleos can exist,

08:46what else is out there,

08:48waiting to challenge everything we know about the universe?

08:54That's it for today.
