Astronomers Capture First Image of a Black Hole

The Event Horizon Telescope (EHT) — a planet-scale array of eight ground-based radio telescopes forged through international collaboration — was designed to capture images of a black hole. Today, in coordinated press conferences across the globe, EHT researchers revealed that they have succeeded, unveiling the first direct visual evidence of a supermassive black hole and its shadow.

The image reveals the black hole at the centre of Messier 87, a massive galaxy in the nearby Virgo galaxy cluster. This black hole resides 55 million light-years from Earth and has a mass 6.5 billion times that of the Sun.

Supermassive black holes are relatively tiny astronomical objects — which has made them impossible to directly observe until now. As the size of a black hole’s event horizon is proportional to its mass, the more massive a black hole, the larger the shadow. Thanks to its enormous mass and relative proximity, M87’s black hole was predicted to be one of the largest viewable from Earth — making it a perfect target for the EHT. 

The shadow of a black hole is the closest we can come to an image of the black hole itself, a completely dark object from which light cannot escape. The black hole’s boundary — the event horizon from which the EHT takes its name — is around 2.5 times smaller than the shadow it casts and measures just under 40 billion km across.

Hello Everyone! I have been working for the past few years on my Undergraduate degree and in order to graduate this May I need to complete a final project. I have decided to look at the effect of the December update on Tumblr’s online community.

If you have a moment please take my survey and tell  me what you think about the new changes.

 https://forms.gle/TQpnGkV249Vs6RCB7

Thank you for your time~!

Just thought I should mention the survey is only going to be open for a week! so until Apr 14th. 

If you have questions please message me! 

Hey fam! If you could please take a moment to look at this questionnaire and fill it out that would be great. @yusaofthedawn actually interviewed myself and a couple of other content creators on here for their thesis, but they need more data to work with.

It takes less than two minutes to fill out, and you’ll be helping someone finish their undergrad thesis. Thank you!

please consider NOT pouring your dog or cat’s kibble directly into a plastic container for storage. the oils and fats in the food oxidize quicker than you’d imagine, get into the plastic, and become rancid. this badness then creeps into new food you pour in! i won’t get into all the scientific terms right this sec, but it can cause cancer and other major issues

ideally, kibble will be kept sealed IN the bag you buy it in (chip clips are your friends). the bags are designed to keep all the good juices inside. you CAN put the bag in a metal or glass container if you wish. HOWEVER, any bag of dry food WILL oxidize and start to go bad in 2-3 weeks once opened! that’s right, stop buying jumbo bags for small dogsonly one dog. buy lots of smaller bags if you want but please don’t open them until you need that food. to all the people wondering why their dogs get tired of their food by the end of a bag or start to get sick, this is why. the entire chemical makeup of the food has changed.

i’ll save all the things i Could say about what should and shouldn’t be in your pets kibble for another post, maybe, or for anyone who has questions just hmu. i’m here to help the floofs be healthy

if two people sleep in a bunk bed do they have to share a monster

‘our humans are sleeping in bunk beds and we have to share the space under’ is one of the three most popular fanfiction premises in monster AO3

“there’s only one under-the-bed”

now THIS is the romance I want to read

I’m sorry I know I just reblogged this, but I can’t stop thinking about it.

“Look, just stay on your side and I’ll stay on my side. We can make this work.”

“That’s all very well for you to say, you’re not facing the wall.”

“What’s wrong with that?”

“Oh nothing, nothing at all. I’ll just let you get on with all the prime ankle grabbing shall I?”

“Oh for…look, do you want to switch sides?”

“No, no don’t trouble yourself. I’ll just lay here, and maybe pull on that blanket corner for a bit. That ought to really inconvenience them.”

“Right, I’ve had enough of this, come here.”

“Here! What are you doing?”

“Just shut up and give over. Just, give me your claw.There, see, now we can both grab an ankle if we get a chance.”

“…Right, yeah…okay…”

“Okay then…”

“Uh…“

“Yes?”

“Uh, could you maybe not, wiggle…with your tentacle it’s…it’s in…places…”

“Oh shit sorry, didn’t realize, is that better?”

“Y-yeah…”

“….”

“….”

“Dave?”

“Yea?”

“Is that your tentacle?”

“UhhHHM.”

“Oh my god.”

“Look I’m sorry but you’re the one who started it!”

“I most certainly did not!”

“You did! You’re the one who wanted to spoon!”

“Because you wouldn’t stop whining!”

“Look, just…just ignore it okay, it’ll go away if we don’t think about it.”

“…fine.”

“Fine.”

“…Dave?”

*sigh* “What?”

“What if…what if I don’t want to stop thinking about it…”

When do you sleep?!

EDITED, Because I was wrong on some facts. Thanks tumblr people for correcting me.

Humans are (supposed to be) a daylight species. We have excellent colour definition, possibly some the best in the animal kingdom, depth perception which is second to none and excellent ability to detect movement and spot predators who are even camouflaged against their usual prey. Our circadian rhythms are tuned for daylight hours. We wake with the sunrise and get sleepy with the sunset. 

We have poor night vision and humans are, from birth, afraid of three things; the dark, falling & loud noises.

However…. some people seem naturally night people, working at their best as the sun goes down and staying up all night to work or play. The rest of us can adjust our rhythms For some people it’s easy, others not so much but we can still do it and usually with only a couple of days to adjust fully. We can work night-shifts and sleep during the day; the exact opposite of what we’ve evolved for. And should our night jobs end and go back to day jobs, we adjust back even quicker. No other animal on the planet has the ability to adjust its natural rhythms as well as we do. Day creatures can be trained to work at night, night creatures can be active during the day, however they are known to be uncomfortable and not at their best during these times. 

It makes sense that spaceships would have some kind of day/night cycle to help people maintain normal circadian rhythms. with brighter lights during the day and dimmer lights coming on at night.  So, imagine aliens, either nocturnal, diurnal, or crepuscular (most active at twilight). Yet no matter when these aliens wake up, there’s always a human kicking around and doing stuff and they seem to be working at their best like this is their natural time. 

Human: *is getting 3am bowl of cereal*

Alien: Why are you awake? According to your biology you should be in a state of rest.

Human: *through a mouthful of crunchy nut* Yeah but I didn’t feel like it

Alien: frowns, but nods

*next morning*

Human: *is munching on crunchy nut*

Alien: wtf I saw you doing this 3 hours ago

Human: *groans* coffee

Alien: Whahat are you doing according to your circadian rythms you should be asleep for at least 4 more hours

Human: gotta go to work my dude

Alien: then why were you awake at 3am

Human: *shrugs* I was hungry

Alien: *internal screaming*
