Hubble Makes Unexpected Dark Matter Discovery

Astronomers seem to have revealed a puzzling detail in the way dark matter behaves.
They found small, dense concentrations of dark matter that bend and magnify light much more strongly than expected.

I've always wondered what educational space videos narrated by a disney princess would sound like... There's a market for this...

[Krafterr]

Beautiful, wonderful discoveries of our universe. Fantastic, thank you, NASA Goddard.

[youxkio]

Nice. I didn't know that dark matter could make a lensing effect.

[khybher]

How can you discover that which you cannot prove to exist?

[benm]

"mysterious universe" seems a little understated.

[Dbazzjones]

Wow... When was dark matter found? I wasn't aware that its existence had been substantiated.

0:49 - could someone help me understand if this is a correct depiction? there's no blob of dark matter just hanging around in inter-galactic space is there? i thought it has to be within a galaxy -- they don't seem to show any galaxies where this dark matter is shown in this diagram, which seems to me just hanging around

Someday, an accidental discovery will drastically boost our technological capabilities as a race and possibly enable interstellar travel so that we can finally travel distant stars...

Someday... a man can dream.

Have to remember that dark matter is a name for something we don't understand yet, it has not been actually detected in any way.

[ffggddss]

A small, but important disovery. It remains to be seen what will really come of this.
Dark matter is a somewhat nebulous, ad hoc hypothesis, which may survive further discoveries only in some modified form. Or it may not survive.

¡Qué magnífico descubrimiento, saludos a los científicos y técnicos que trabajaron en un proyecto tan significativo, felicitaciones!🌞🌈👍

[StanTheObserver-lorx]

Not even an educated guess as to why? Take a stab at it!

[MausMasher]

Does this also mean that Unicorn's were/are, real too????

[DwainDwight]

Great video & agree. so much we don't know.

[AmitSingh-hzgt]

If dark matter doesn't interact with EM waves, how does it cause distortions equivalent to refraction?

[deeprecce]

One shldnt jumb to conclusion, with limited observational capabilities and exposure and incomplete models, more information and studies are required..

[BM_brb]

how can we know that it isn't just a blackhole?

[mikeportjogger]

Perhaps there's more than one type of dark matter?

[dubsar]

Dark matter is made of our unheard prayers and pleas in a godless universe.

What if dark matter is a parallel universe to this one? Like a negative universe just like with photos. A positive photo and a negative photo.
