Would be great to do a technical deep dive into the engineering (HW, SW & Mech) used to build and run GAIA. Just a few tantalising hints in this video!
This is the opposite of click bait. Thiskept appearing on my feed, I clicked on it, and really enjoyed it. I'm now going to get a lot of magnets from hard drives, a really strong motorcycle helmet and a very long snorkel and aim for Alpha C. I might need a really big mobile phone to let you all know what I find.
*SPACE EXPLORATION LEADERBOARD* The telescope laypeople know about: Hubble, and now JWST The telescope that gets mentioned in basically every astrophysics topic: GAIA The telescope which is the most under-rated: Chandra XRO The telescope which is the most hyped: JWST, and now Vera Rubin The telescope which has surpassed its original mission objective by the largest margin: Voyager 1, Hubble, or Opportunity depending how you measure it The shortest-lived telescope to collect groundbreaking data: Venera 7, Galileo Entry Probe, or Huygens _I realize that I'm really stretching the definition of telescope at this point._
capabilities driven frameworks are great, but lack a unifying vision to spark public interest and therefore funding. Take a look at the supercolliders and even the space station projects. If you have a unifying vision to group these tasks together in then you are more likely to get them funded, get popular opinion and support and achieve the very steps you wanted to achieve with the framework. The risk of course is that if you do not have the skill to manage the project, are easily pushed around by self interests and those being funded are not delivering on their promises to deliver, but instead using the project as a giant cash teat to suckle from, then the vision flounders and you can lose all momentum. Have a guess where this artemis project is heading....
The Germans were the first to send a radio message that bound deep into space, in the NSDAP era I believe. So if we start hearing angry German back we know we have something
According to the most recent video from John Michael Godier channel, astronomers have already discovered from Gaia data no less than 53 candidate stars for potential alien Dyson Swarm systems, based on excess infrared emissions compared to the natural spectra of the host stars, with up to 16% light blockage per distance and correlated 60x more infrared than expected. Whether it's really aliens or a whole new function of system properties, there are some serious scientific explorations to be done with them.
I have a question: I know that in order to determine the shape or the universe there are two ways; either draw a *giant* triangle and measure the sum of its angles or see if two parallel lines stay parallel. How on earth (pun intended) did we do that?? Surely I'm missing something. Can you please explain?
As long as there are nations like Russia and North Korea I don’t see a good future ahead. We are close to ending democratic nations and could be on the verge of a long decline.
@@pilotnamealreadytaken6035Remember when James Webb’s design was finalized there was no realistic way to reach it with a crewed spacecraft and robotic spacecraft that could repair or refuel it don’t even exist now. And before anyone mentions Starship, which still isn’t operational yet, this was before SpaceX had been founded. In addition, I don’t have to remind anyone how the costs for JWST ballooned. Adding repairing and refueling capability would have further added to the costs and the time needed to complete it. The Hubble Space Telescope is the exception not the rule because it’s in an orbit that could be reached by the shuttle, unlike JWST. So, they made the right decision at that time and it wasn’t a design flaw.
Hey Fraser. The definition of the Big Bang in the pictorial of how it is shown, explains that the explosion only gravitates one way. Thats not in keeping of laws of physics UNLESS - there was something solid in the other direction which forces the explosion to go one way. A Black Hole Perhaps? Otherwise, there is 13.8B light years in another direction? This then defines the universe as being 27B light years point to point?
I know Gaia doesn't operate in the ideal frequencies, but were any observations of Oumuamua made by Gaia? Would a longer wavelength IR version of Gaia (GaiaIR+) be good for cataloging near Earth asteroids?
id love to join the panel to discuss some of the current events, and proposed future we may encounter If there is a 1 way ticket to get things started on mars or moon i got the skills but not the time for return. love your stuff keep it up
(removing question, it was answered late in the interview. Whoop! So here's a new one...) To what extent have we run into the theoretical resolution limit (1/2 wavelength) for visible-spectrum light? With 2 meter telescopes (i.e. Hubble) at 500nm, that's the 60 milliarc-seconds mentioned.
При детектирование гравитационных волн LIGO, полезный сигнал 0,2% на шум приходится 99,8%. По другому можно сказать. - Если случайно совпадают шумы (мусор), на двух или трёх детекторах, то выдадут это за гравитационные волны, согласно подготовленных заранее шаблонов. На “ГИБРИД оптическом гироскопе" при регистрации, квантов гравитации оптом. Возможно полезные сигнал получим 74% и на шумы 26%. - Вам выбирать рулетку, что измеряет Вселенную и из чего, главное она состоит. Итак садимся в автотранспорт или самолёт и в нём выполним опыт Майкельсона-Морли, определяя им прямолинейную скорость. - О таком опыте мечтал ещё Эйнштейн. Но мы, возможно будем наблюдать постулаты "Свет это упорядоченная вибрация гравитационных квантов. Доминантные гравитационные поля управляют скоростью света в вакууме". Есть предложение на совместное изобретения ГИБРИД гироскопа из некруглых, ДВУХ катушек с новым типом оптического волокна с «полой сердцевиной из фотоно-замещенной вакуумной зоной», где - свет в каждом плече проходит по 16000 метров при этом, не превышает параметры 0,4/0,4/0,4 метра и вес - 4кг. Предприятия по выпуску "Волоконно-оптических гироскопов" может выпускать ГИБРИД гироскопы, для учебно практического применения. Жавлан.
Given the extended mission length will the motion of the solar system within the Milky Way galaxy give a longer baseline than the 2 AU baseline formed by rotation about the sun?
@@RectalRooter The sun is moving around the galaxy's core and over the length of Gaia's mission will the spacecraft have moved further away from its starting point than the 2 AUs that it moves when considering only its orbital movement about the sun.
@@chrisclark6154 Ok Ok.. Got it. It's a length vs width thing. We might be able to do the math from what is said in the video. The guy mentioned how fast our solar system is moving - So that times the 10 years in service and then subtract what 2 AU's are.. Right ?
Question: Hypothetically speaking, what's the best resolution image we could make of a terrestrial exoplanet, given all the photons from it that arrive at Earth over an entire year?
He admitted the Gia team withholds information. I'm starting a rumor that the Gia team is withholding the discovery of a Cryogenic Rouge Planet is heading to an Earth Collison
I like this Spaniard. He is humble and wants to give more info but knows he will suffer. He will probably be running the Spanish Space Admin in the next 20 years.
Didn't he say Gia has a brightness detection of 21 and higher ? I wonder if seeing dimmer stars fill in the empty space more than near IR. North Star or Pole Star. With an apparent magnitude that fluctuates around 1.98 Maybe those are different ways of measuring
If we were going to plan to populate the galaxy, where should we head with our von Neumann probes after the nearest stars? Inwards along the galactic arm or hop over towards the next arm?
