There was a TV manufacturer back in the early 60's called Quasar. Their slogan was "Works in a drawer". You could literally open a little drawer with the circuit boards inside!

Furthermore, insinuating that astrophysicists and enthusiasts lack people skills is just plain disrespectful. These are individuals who dedicate their lives to understanding the complexities of the universe, often communicating their findings with precision and clarity. What really gets to me is how utterly pointless this comment is. It doesn't add anything constructive to the conversation about quasars or anything else. Instead, it just spreads negativity and reinforces harmful stereotypes.

But what really baffles me is why someone would mention their expectations just to knock down the same thing they're trying to stand for. It's like shooting yourself in the foot. If we're advocating for understanding and respect, let's actually embody those values instead of undermining them with thoughtless remarks. We need to create spaces where everyone feels welcome to share their insights without fear of being dismissed or belittled. That's how we can truly foster a culture of learning and mutual respect.

While your sentiment might reflect a common fear of cosmic extinction-level events, it's crucial to approach such assertions with a careful consideration of scientific evidence and preparedness measures. Firstly, dismissing concerns about astronomical events, including the potential impact of asteroids, could undermine proactive efforts to safeguard against such threats. Initiatives like NASA's planetary defense programs, including recent trials aimed at redirecting asteroids from collision courses with Earth, demonstrate proactive measures to mitigate potential risks. For instance, NASA's Double Asteroid Redirection Test (DART) mission aims to test the effectiveness of redirecting an asteroid's trajectory by impacting it with a kinetic impactor. However, it's essential to recognize that while these efforts demonstrate technological capabilities, they do not eliminate the need for ongoing monitoring and preparedness. The impact hazard from asteroids and other celestial bodies remains a real and significant concern, and continued investment in detection, tracking, and mitigation strategies is essential for ensuring the safety and security of our planet. Regarding the suggestion that it might be better not to know about a cosmic extinction-level event, such a stance raises ethical and practical considerations. While uncertainty and fear surrounding catastrophic events are understandable, informed decision-making and preparedness are critical for minimizing potential impacts. Ignorance of impending threats would leave humanity unprepared and vulnerable, with potentially devastating consequences.

5:33 Man, I forget how incredibly vast the galaxy is at times. To think an entire galaxy is rotating around such a small dot in the center is just mind blowing.

When I was a little girl I got an astronomy dictionary, and I don't recall it saying "quasar" was a "quasi-stellar radio source," it said "quasi-stellar object." I didn't know that the radio part of the e-m spectrum was important for a quasar till I watched "The Quasar Enigma" from "How the Universe Works," prolly my favorite episode of all (I've seen it innumerable times!)

Loved it…. Thanks for creating Alex and team… 😎

Also I love the irony that we detected the first microquasars within a year of discovering Cygnus X-1 but it would be about 14 years before there was concensus that it was '95% change it's actually a black hole' (quoting Prof. Hawking haha). Science is fun like that sometimes.

JWST has been SO worth the trouble.

I thought a quasar was specifically defined as an active galactic nucleus? Have they expanded the definition to cover any active black hole?

you are most likely seeing a typical neutron star. neutron stars tend to have appearances similar to quasar. with electrons forming a halo around it(because they cant go between the neutron star core body anymore technically making it a gargantuan single atom). and the gravity emission at the polars excites the electron ring that are lit by it and produce a visible weird light pillar effect. which again, makes it looks like quasars. but its not. mind you quasars dont start small.

Yeah, no. There are no quasars in the Milky Way. Microquasars - although carrying a similar name and probably being based on similar mechanisms - are not Quasars. They're tiny cousins - nephews, if you will - of Quasars, but they do not belong in the Quasar category. (For starters, they don't appear as point-like objects, so don't qualify as Quasi-Stellar.)

I'm seeing it more and more lately, creators are using the screen to ask for things like patron or show ads and I don't mind it. It's far less disruptive than halting an interesting video to do an ad or ask for memberships. This is an improvement. I just hope other creators don't take it to the extreme and make it invasive like ads of the past.

If you want to see the image of the "spotted" quasar, go to a different video. Alex won't show us.

As usual, excellent vid.

I just finished taking a long exposure of the Needle Galaxy and saw a few Quasars identified in the area. I didn't know they were in our galaxy but I can see why they would be since a black hole can form near a companion star. I guess a gamma ray burst is a black forming inside a massive star before the outer layers are blown away. That black hole is eating the star before it even fully explodes.

I wonder how fast one of those micro Quasars could cook a Chicken? Just trying to think of a practical application for them.

Two jets is just conservation of angular momentum. If it was one sided it would accelerate the black hole no? Jets have nothing to do with Hawking Radiation (We think; No one actually KNOWS what causes jets because only radio loud feasting black holes make them. Why are some feasting black holes radio loud? 🤷‍♂). Hawking radiation is the hypothetical black body radiation of a black hole and it required a math trick. All objects that have temperature emit light. We humans emit infrared. Figuring out "why hot thing glow that color" was a huge step in our understanding of quantum mechanics. Hawking "found" this radiation by examining quantum fields infinitely far away from the black hole. Basically a limit if you're familiar with basic Calculus.

Notice it is this specific quasar that this is occuring at, not a set of quasars that we've observed this at? I'll admit I probably misunderstood your comment, however, the topic of jets in general is something that is not well understood and is an field of active study.

Fascinating episode, wonderfully narrated. Magnetic pulses are something new to add to behaviour of particles in space.

Basically, all existence, for us, is an explosion slowed down to a near standstill and all of the debris in the explosion is acting according to physics. Our entire existence begins and ends in a minute fraction of time within our reality and as a blink in the big bang explosion. Since our lenght of time is so extremely finite, do we really exist?

Quasars tend to have very active accretion disks and their characteristic relativistic jets. Blackholes with less active accretion disks (or no accretion disk) and no relativistic jets are not quasars.

I think the most surprising thing is actually how far we have come from not knowing to building an understanding of quasars.

I love quasars. I tend to buy a family share pack at the supermarket and my favourite flavour is smoked BBQ beef.

"would you believe me when I tell you we have the best of both worlds, quasars in the milky way that we can see and study without it destroying us, but you might ask *how can that be possible?!* it is possible, thanks to our sponsor Quasardash, bring it right to your doorstep"

I can bet on my life, that in 10 years nothing in this video will be relative anymore.

How is stellar fusion affected in the giant stat when it has a massive (stellar or collapsed) partner? What constitutes the center of fusion when there are tidal effects? How does a stellar object's fluidic body orbit its center when that center is offset by a massive companion? Does that offset have impacts on the growing layers of fused materials as the star ages and passes through age-phases?

I generally run around in fear of what lurks in the cosmos -- human beings topping my list, of course.

Nothing to worry about. Nothing has happened till now and that quasar has been around for as long as the galaxy we revolve in.

"To accept the things I cannot change; Courage to change the things I can; And wisdom to know the difference." That's the answer to the question of "Should we be worried?"

SagA* wouldn't pose any threat to Earth if it was a Quasar. It wouldn't have even been discovered until all the other Quasars were found. It would have to be within 33 light-years, where it would look like a second sun, to pose any harm at all.
