Asteroid 3200 Phaethon got closer than it will be until 2093, and the reflecting light has astronomers puzzled, and the relationship between black holes and magnetic fields is now a little more clear.
Correction: The writer for this episode was actually JD Voyek.

So its eating torus?
Black Holes are spheres, right? Hole implies 2d, always hated that
3:19 I have some questions.
Perhaps it’s just terribly terribly sad.
Watch the Science Channel.
Question. How does electromagnetism escape the black holes gravity?
it’s blue because if it was green, it would die
Isn’t the Parker Solar Probe the named object that gets closest to the Sun?
I didn’t know about the Sofia telescope either, Hank.. You’re not alone in this, so don’t worry too much about it..
A separate video about that plane please.
@3:38 Galaxies*
Its orbit makes it a bit lonely. I would be blue too.
things that fall into black holes scream in ultraviolet
I’m confused on how can a black hole produce a magnetic field from inside it’s event horizon. Is the black hole creating the magnetic field or is it the ionized plasma trapped in orbit around the active galactic nucleus?
They ate everything within range already
I have had the lucky opportunity to watch SOFIA in action. The mission conducts its operations out the city I live near in New Zealand, and seeing it land and take off is such a sight to behold
The Black Prince is a weird space rock. Magnetism or the impossible to find dark matter, which is really the missing mass.
I’ve seen this before. #TheExpanse
maybe its made of titanium and the suns heat is “bluing” it?
I actually got to fly on a SOFIA mission, it is indeed one of the coolest telescopes out there. Fun fact, they had to add extra metal plates to the front for ballast, so that the plane flies level with all the equipments in the back.
I’m a Gemini, but is anyone else here a torus?
Hank is the best
Hi SciShow! I’m the author of the Cygnus A results you show on this video. I do also work at SOFIA
Thanks a lot pick our research, the explanation is fantastic! I’ll take notes and explain it with those simple words on my talks.
I am amazed that you didn’t know about the 747 mounted telescope. It has been on the internet for years and in science magazines and tv shows.
LAPIZ LAZULI??
Comet shards are blue so that’s why it’s blue
If you’ve never heard of the Sofia telescope, then you probably haven’t been following the SETI Institute closely
Do blackholes travel around the center of our universe?
A blue asteroid named Phaethon? Are you sure it’s not one of those Phazon asteroids from the Metroid Prime games?
no such thing as relationx or not
I assume Thanos is rolling around on the floor somewhere crying.
How do we know the asteroid is blue ? Maybe it is a happy asteroid.
Maybe it’s blue because it’s scorched Iron.
FFS, stop putting text on the screen that says exactly what you’re saying. This is literally how NOT to do an engaging presentation design. It actually impedes transfer of information.
Sulphuric acid heated. That’s your blue
Most likely Asteroid 3200 Phaethon is the baked core of an old comet, which could explain its highly eccentric orbit as well as its colour!
“Well, ah, well, ah. It’s obviously made uh…blue suede…like muh shoes. Thank you, thank you very much.”—Elvis.
Why did the asteroid turned blue? —————————— Cause it couldn’t breath! =D
Get it? Cause its on the vacuum of space….. and there’s no oxygen…..
I’ll see myself out…
Yay~ It’s Hank!
Sophia is great because it can go places other telescopes can’t, like over the middle of the Pacific ocean if that’s where the thing you’re interested in will be visible. It’s not so great because sticking out of the side of an airplane in flight is not exactly the most controlled environment. Lots of vibration and possibility for atmospheric disturbances that will be hard to account for.
Wait is this an episode of the Thunderbolts Project space news?? New and still unexplained asteroid properties and possible galactic scale electromagnetism…?
so when the last sun in the universe dies we could use the magnetic fields of black holes for an weromano sphere (giant electrical black hole motor) !?
Maybe we’ll get lucky and that solar probe will get a close pass at the asteroid at some point during its mission and get a better look
+1 for the electric Universe people.
My takeaway from this video: black holes are the ambush predators of the universe.
cobalt is blue right? maybe it is made of pure cobalt…
I love his style!
Cygnus A is not the closest active galaxy. For example, M87 lies much closer and it has jets too.
that is the sort of orbit I would program into a monitoring drone. just saying.
I’ve seen plenty of these in space engineers, it’s made up of a bucketload of cobalt
Oh crap, we found the protomolecule.
Not hardly, my friend Karen is the hottest thing in the universe
You haven’t heard of SOFIA?
Its probably metal base asteroid and the heat from the sun is heating the surface
Wow, the interplay of the black hole magnetic field with surrounding matter seems like a “well duh,” moment. Yet, I had never even thought about it, and I am the biggest cosmology/astrophysics geek I know. I had never given thought to the emphasis of gravity in pop-science descriptions of black holes, yet it seems so obvious that more forces than gravity would be at work.
I am, by no means, trying to minimize the impact of these observations on greater understanding, but…wow. Here I am with a new spin (no pun intended) on my understanding. …mind slightly blown, though I feel silly for being taken aback. ~shrugz~
*YO LISTEN UP! HERE’S THE STORY, ABOUT A LITLE GUY THAT LIVES IN A BLUE WORLD*
Blue is probably from Basalt.
I’ve seen The Expanse. I know what’s going on here
Hank for President!
And as for the blue colour of the asteroid, could the high energy particles coming form the sun be responsible. I have seen metals change colour when bombarded by particles.
You still believe in black holes? Mfft. Bwahahaha. !!!
Of course venus is the hottest on the solar system😁
Imagine how cool it would a SOFIA version of a super jumbo
When glazing a piece of pottery you apply a mixture that includes oxides of various metals. When the piece is fired at high temperatures these oxides undergo chemical reactions and produce brilliant and vibrant colours, including many blues. Maybe this asteroid has an abundance of cobalt oxide and others.
I think anthropomorphising black holes by using the “feeding” metaphor is overplayed.
We should name that asteroid: Icarus
Da fuq… a telescope plane. That’s awesome.
So, magnetic force can reach out from a black hole.
Obvious Element Zero -rich asteroid. If only they could mine it…
Blue asteroid? You need to bone up on your Marvel! The Blue Zone on the moon actually had an oxygen atmosphere. (look for Fantastic Four and Goliath in Marvel comics)
I suspect it’s a Nitrogen doped diamond (which are blue)… Considering how hot it gets, it’s possible.
maybe it has a high copper content?
why is blue such a weird thing? blue isn’t that weird.
if it were covered in equally spaced pokadots that would be weird… blue isn’t weird. it’s just a wavelength of light.
The blue asteroid is very strange indeed. Thanks for another excellent video!
4:12 I like how the subject title card retracts like a projector screen being pulled and released. Very “science classroom” detail.
What if there was no black hole and it was all electrical?
I mean, we’re observing plasma, which is governed by EM, not gravity.
What’s the theoretical upper size limit of SMBHs? And what weirdness could it inflict on the regular universe?
Holly molly!! Why no-one told me about that cool NASA telescope!? 😂
“I’m your Venus, I’m your fire, at your desire.”—Shocking Blue.
It’s actually Energon
Scientists and researchers, bringing us no less of a dark age than religion did.
/watch?v=MYqOidE5aGo&t=1s
I love what you do for this channel it’s amazing your work
The original Blue Moon more natural than our own.
Perhaps this asteroid has loads of sapphires like the one in “Moon Zero Two”.
Talk about the Parker solar probe
It’s blue because it’s a Smurf planet…geez figure you’d know that 😝
Phaethon 3200…an Interstellar space TOILET breakaway piece…TP NOT INCLUDED!!
I knew about the Sofia telescope. I’m a nerd 😔
I actually made some parts for SOFIA while I was working for the NASA Ames machine shop. Neat to see that thing still in use.
Upon reading the title: “Protomolecule?”
Upon watching the video: “Well it’s not confirmed to NOT be protomolecule.”
This asteroid must be where Eiffel 65 shot the music video for Blue (bah buh dee)
Protomolecule? #TheExpanse! Better be careful.
Ok can we get a video about different weird telescopes
If Phaethon were mostly iron, then 700c would be about the right temperature to turn it blue. similar to tempering a piece of steel. the colour changes are relative to temperature
That 747 has been a thing for years.
I hope it feels better soon.
It’s blue because it didn’t listen to Willy Wonka
I love that you guys include your sources! It’s so important to highlight to the researcher’s hard work. Also, listing sources is how combat “alternative facts” and misinformation!
Yes. We need to know more about that 747 with a telescope in the side!
It’s blue because its circulation is cut off at the waist. It needs to loosen its asteroid belt.
