JWST discovers NEW PLANET - it's the coldest, oldest exoplanet ever imaged

I've been a rochet engineer for decades and have seen rockets mature from engineering marvel to a routine vehicle no more newsworthy than railroad locomotives. This is of course as it should be.

I have troubles calling Roman a "Hubble Successor" as it was originally named "Wide Field Infrared Survey Telescope". LUVOIR is much closer in nature to Hubble. BTW: LUVOIR-B would dwarf Webb.

First class channel Becky!! 👏👏

Dr Smethurst - thanks for another great video. I'm not sure if I have this right, but when comparing the survey size of Euclid and Roman, the values shown are *squared*. An area of 15,000^2 units is actually 56.25 times an area of 2000^2 units (not 7-1/2 times). The part I'm not sure about is the fact that the units are degrees. It seems to me that the math would be the same regardless of the units being used, but there are probably countless reasons why you're an astrophysicist and I'm not!

Anyway, I've been a fan for years - thank you again for what you do, and keep on smiling.

I think the NGRST should have a mirror twice the size of the HST. At least.

There is also the Chandra X-ray telescope, which NASA may simply abandon despite it still being operational and pretty unique in capabilities.

Great article, thank you!

They will test the optics before launch ... won't they?

Is Dr Becky a McLaren fan? Team Papaya.

Nobody: "How often do you think about the Roman Empire?" Everybody: "Pretty much every day." - lol

Maybe throw a couple extra gyroscopes on it?

Blg hi from new Zealand love your views on mental health 😊

Better Help settled a law suit to the tune of $7.8 mil for selling personal, intimate mental health information to social media platforms. We can do better with sponsors, no?

Why are calling it JWST? Just call it by name - Webb.
Are you calling the other space telescopes by the initials?

I hope they start making 2, 3, or 4 of each telescope for multiple reasons and set up a robotic manufacturing facility so they can shorten manufacturing time and start using standard box casings to speed development!

Old Mother Hubble
Looked at a bubble
And said that the cosmos is round
“With dark energy floating
To hasten its bloating
I wonder what else could be found?”

Don't get your hopes up. We're Broke...the USA is Broke. WW3 is around the corner. The economic crash is upon us.

The Hubble Space Telescope happened because it was the cover project for the KH-11 spy satellite, not for astronomy advancement. There were at least 3 KH-11 spy satellites made, Hubble and Nancy Roman are two of them. The Space Shuttle was originally designed to be launched on a runway and land on a runway, Single Stage To Orbit, SSTO. The Air Force changed the specifications for the Shuttle Orbiter to carry a Pay-Load the size of a school bus that weighed 30 tons. That completely upended the original Space Shuttle design, requiring the problematic launch system it ended up with. The KH-11 required final assembly by astronauts, the reason it was deployed the way it was.

NINETY PERCENT WAS AWAY OVER MY HEAD But Thank You for the Link to Betterhelp ;

I love the way you explain the very complex things you are talking about. You do so in layman's terms. Plus I'm embarrassed to say I checked out your videos because I thought you were hot. Hot and smart is a good thing in my book.

The space telescope in the Roman spacecraft is one of two Hubble class space telescopes that were donated by the department of defence to NASA. These telescopes had been intended to be used in spy satellites before the design of spy satellites changed. It is astonishing to me that the DOD has funding to launch one or more Hubble class space telescopes each year to look down at Earth.

I think that the spare telescope could be launched to orbit Mars. This spacecraft could be a largely unchanged spy satellite to spy on Mars instead of the Earth which would drastically cut research and development costs for this off the shelf Mars orbiter. It could also be used to relay data from Mars landers when the current rather old Mars orbiters used for this task run out of fuel.

What we need is a plan for a telescope to be lauched on SpaceX's SuperHeavy/Starship combo. You can lift something in excess of 100 tons and the diameter means a 8m yes an 8m primary mirror is realistic

Isn't it nice of the NRO to donate unused hardware to NASA? This time they even donated two satellites! 😉

Though Betterhelp was an ad, I wish to congratulate Dr. Becky on taking steps to improve her emotional health.

Love, love LOVE your channel, Dr. Becky! 💖

I'm sure it will take a while to build. Roman wasn't built in a day.

Newton's law of motion, F=ma. Acceleration is undefined, unbounded, infinite.
E=mc. Acceleration is defined, limited, bounded, finite.
An infinite universe bounded (observable) by the speed of light.
There is no cosmic center. There is no expansion. Only a visible bubble (observable universe) that extends out to the lifespan of c in the visible light spectrum.
Light propagates through space. For every action, there is an equal and opposite reaction. To accelerate mass forward, you have to accelerate mass backwards. Thats why photon's redshift/lose energy. Each wavelength is a jump point. You can go this far and no farther and a new photon is propagated.

F=ma. You have either an external force (F) accelerating the universe, or the universe is accelerating itself (ma).
Either way, E=mc. Its an infinite universe bounded by c. Meaning, mo matter where you go, you are at the center of the observable universe.
There is no age to the universe. Just a cosmic light bubble that surrounds you.
You can see that with JWST. Fully formed galaxies in the early universe. The Milky Way galaxy has only done about 60 rotations in 13 billion years. 13 billion/225 million years for the earth to complete a galactic year. There was either a lot of acceleration taking place or a lot of time to form the galaxy structures.
Light, like all acceleration, has a cosmic time limit for it to stay in the visible light spectrum before it redshifts into the CMB.

Heraldedededed for the Oxford dictionary plz.

Untill we actually get a telescope with Hubble's capabilities I.E. visible light to slightly touching both ultra violet and infrared then. No telescope can ever be called Hubble's succesor!!!!

Mental help is a good thing, however when more comments are about a sponsor than astronomy itself we are essentially telling Dr Smethurst that we care little about her intelligence or information. Instead we would rather take over her entire platform as a crusade against this sponsor for our own selfish purposes.

This is not the place for such a crusade.

What do we know? We know that we have detected Gravitational waves in space. That means that space is truly a fabric a thing that's substance. If a graviton wave can exist in space, then it seems to figure That if space is accelerating away counter to gravity, then maybe we're overthinking it. Lots of external forces set things into motion against gravity on Earth and send things flying in the opposite direction. The only difference is in space there would be nothing to slow down that momentum like it would on Earth. It seems to me with all the volatility in the universe and if gravitational waves do exist. Then tides would exist in space as well. It would be impossible to measure right now but I would bet that there are ebbs and flows in space just like in the ocean and that the ocean itself and space itself are extremely similar except for the fact that space would not have gravity affecting it as intensely as it does in an ocean on Earth. So the energies that they are looking for probably don't exist they're just a natural reaction to the matter and actions taking place in space from explosions of stars gamma ray burst and black holes. These would be the mixing pot of the solar fabric of space itself creating vast tsunamis Space waves moving entire galaxies and everything in its path with nothing to slow it down, in fact gaining speed beyond the light speed limit due to continued crashing of waves

100 * bigger than probably 200 times more edited I feel like it is crucial to put that information out there that it's freaking edited nasa uses basically photoshop on crack directions to edit the images I'm not saying they don't have amazing telescopic power but the colors that's someone's fucking idea of what it should look like

Make sure to talk about Nancy Grace ROMAN 'cause I didn't know her & when I look for Nancy Grace, I end up with a TV lady specialized in crimes & other horrible stories 😝😝😝

A DEI Telescope. Nice.

My wife is working on this satellite and it's very exciting! Thanks for covering it!

If they put the Roman telescope in front of the Hubble?
Sure it would need some precision control elements but couldn't they increase the range even a further 100x ?

I am from Kazakhstan. My biggest dream in life is to see high-resolution images of Earth-sized exoplanets. I understand that this is very complicated now. So far, it seems like fiction. Perhaps if scientists from around the world work together to aggressively research this issue, a faster result can be achieved. They need money, cooperation and incentives. But most of the world's money continues to be spent on armaments and wars. Unfortunately, humanity is still very wild.

I tested the engines for this program. I can't wait until it launches

lol, thanks for sharing, we all wait on pins and needles latest accomplishments. In this example your most recent advertising agreement. Kudos Doctor.

Thank you for explaining what Roman will do for us.

making sure to subscribe because I'm sick of tabloid astronomy channels spamming JWST news searches.

The Roman telescope main optical systems were donated from the NRO - National Reconaissance Office. The NRO builds and maintains the spy satellites for the USA and they had two of these telescopes lying around in storage and donated them to NASA in 2011. NRO began using this telescope design in 1976 and the NRO considers them obsolete, even though they are still considered state of the art optically. So they they think these telescopes are obsolete, yet good enough for NASA and NASA agrees. Imagine what the capabilities of their current telescopes must be- um wow.

I’ve just discovered Dr. Becky and her channel. It’s incredibly refreshing to be able to watch an explanation on something complex where the narrator takes the time to explain what each concept is, during the presentation. I usually find myself spending too much time exiting what I’m watching to Google some of the more complex terms. I have no experience in this world, just a keen novice, so thank you Becky, for being so wonderfully accessible! Great video on the new telescope, and I fully intend to work through your videos to learn more 😊

Unfortunately, it looks like the telescope won’t be launched into orbit.

Hi.🎉

I'M SURE THAT THE ROMAN SPACE TELESCOPE WILL REVEAL LOTS OF COSMIC WONDER'S!❤

As an amateur astronomer and a member of Planetary Society, I’m completely heartbroken over the devastation to NASA.
