Webb and Hubble Compared “Hubble Ultra Deep Field”



The capabilities of NASA’s James Webb Space Telescope’s Near-Infrared Camera are on full display in this comparison between Hubble’s and Webb’s observation of the Hubble Ultra Deep Field. The left, which demonstrates Hubble’s observation with its Wide Field Camera 3, required an exposure time of 11.3 days, while the right only took 0.83 days. Several areas within the Webb image reveal previously invisible, red galaxies.

Image of star formation in the Rho Ophiuchi cloud complex, with compass arrows, scale bar, and color key for reference.



The first anniversary image from NASA’s James Webb Space Telescope displays star birth like it’s never been seen before, full of detailed, impressionistic texture. The subject is the Rho Ophiuchi cloud complex, the closest star-forming region to Earth. It is a relatively small, quiet stellar nursery, but you’d never know it from Webb’s chaotic close-up. Jets bursting from young stars crisscross the image, impacting the surrounding interstellar gas and lighting up molecular hydrogen, shown in red. Some stars display the telltale shadow of a circumstellar disk, the makings of future planetary systems.

The young stars at the center of many of these disks are similar in mass to the Sun, or smaller. The heftiest in this image is the star S1, which appears amid a glowing cave it is carving out with its stellar winds in the lower half of the image. The lighter-colored gas surrounding S1 consists of polycyclic aromatic hydrocarbons, a family of carbon-based molecules that are among the most common compounds found in space.

We need to get off of this rock. I think that everyone in this thread agrees.

I imagine a large spacecraft with 1000 scientists, doctors, nurses, engineers and manufacturers traveling throughout our solar system for decades before straying outside of it. I hope that I live to see it.

The ship builders could have so many R&D technologies built into the craft. Telescopes that would be 4 times larger than Webb, in all manner of wavelengths.

The clock is ticking. The longer humanity waits, the closer we get to extinction!

Distances in space are too vast. Just to go from Earth to the edge of our Solar System is 9 billion miles. The fastest speed of a spacecraft is 364660 mph which was achieved by the Parker Solar Probe in November 2021. Maximum speed is the speed of light at 671 million mph. The distance from Earth to the center of our Milky Way galaxy is 25800 light-years (a light-year is the distance light travels in one year).

Terraforming Mars is a good first step.

[cabfrank]

Those distances are so vast that they are truly difficult to even comprehend.

A new hour-long Netflix documentary about the concept, design, engineering and deployment of JWST and explanation of images. It took 2 decades and $10 billion to deploy JWST and keep it operating for another decade. There are still Single Points of Failure whereby JWST can cease to operate and there can be no repair missions.

Ok seriously, it's pretty incredible.

LOL!!!!

[Naperville]

I stand on what I said. We need to get off of this rock. The sooner the better because if we do not it is the end of our civilization.



We can remain in the solar system and explore all that exists here for 150 or more years while we better develop our understanding of all sciences/physics, mathematics, engineering/rocketry/propulsion/light speed travel, whatever, but the clock is dangerously ticking. Every picosecond that we do not have dozens of space-going craft with 1000+ astronauts aboard each research vessel, we toss the dice.

We are ONE unlimited nuclear war; ONE major asteroid strike; ONE major pandemic, from setting us back 2000+ yrs or ending life on the planet.



I'm 63. I was younger than a tween when all of this started and it is preposterous that the UN(useless trolls) and the main players have not decided to get off a rock that does not have infinite resources, and protected from the universe and all that inhabits it.

Somebody somewhere has to start a successful campaign to get the job done.

In my lifetime (starting in the late 50's) we have created jet airliners taking people from one end of the earth to the other, compurets that took up a large room to personal computers, landed on the moon, sent space craft to all of the planets in our solar system, created cell phones with a computer and entertainment system built in, electric cars and motorcycles, Cat Scan/MRI, and a boat load of other stuff that I have forgotten about.
Heck, look at the music industry: LP's, Reel to reel, 8 Track, Cassette Tape, CD, iPod, and now Streaming audio. Video has changed in a similar way as well.
Space travel is also evolving from one man vehicles (Mercury), two man vehicles (Gemini), 3 man vehicles Apollo, Sky Lab Space station, Space shuttle with a typical 7 man crew, International space station, Martian rovers, the transfer of government space craft to civilian space craft with the capability of booster re-entry and landing on a water based platform.
Somewhere down the line, a better propulsion system will put us out into space to colonize the the solar system and then we will go to the Alpha Centauri star system that is about 1.3 parsecs (about 4.25 light years) to Proxima C.
That will be an amazing time.

If I understand the technology, fission is used to efficiently turn hydrogen from a liquid state to a gas state to propel the space craft.

Until I read a few large documents on this technology and maybe see a few videos of the way it works, I cannot assume that I know anything. It's totally my fault that I don't know more as I haven't even Googled the subject.

I am sure that the Chinese want to steal it if they haven't already.

I like DARPA but they are too open. The entire USA is too open and all adversaries steal everything tax payers pay for and our corporations develop.

Herbig-Haro 46/47 (NIRCam Image)



These stars have a lot of energy to let loose!

NASA’s James Webb Space Telescope has captured a tightly bound pair of actively forming stars, known as Herbig-Haro 46/47, in high-resolution near-infrared light. Look for them at the center of the red diffraction spikes. The stars are buried deeply, appearing as an orange-white splotch. They are surrounded by a disk of gas and dust that continues to add to their mass.

Herbig-Haro 46/47 is an important object to study because it is relatively young – only a few thousand years old. Stars take millions of years to fully form. Targets like this also give researchers insight into how stars gather mass over time, potentially allowing them to model how our own Sun, a low-mass star, formed.

The two-sided orange lobes were created by earlier ejections from these stars. The stars’ more recent ejections appear in a thread-like blue, running along the angled diffraction spike that covers the orange lobes.

Actively forming stars ingest the gas and dust that immediately surrounds them in a disk (imagine an edge-on circle encasing them). When the stars “eat” too much material in too short a time, they respond by sending out two-sided jets along the opposite axis, settling down the star’s spin, and removing mass from the area. Over millennia, these ejections regulate how much mass the stars retain.

Don’t miss the delicate, semi-transparent blue cloud. This is a region of dense dust and gas, known as a nebula. Webb’s crisp near-infrared image lets us see through its gauzy layers, showing off a lot more of Herbig-Haro 46/47, while also revealing a deep range of stars and galaxies that lie far beyond it. The nebula’s edges transform into a soft orange outline, like a backward L along the right and bottom.

The blue nebula influences the shapes of the orange jets shot out by the central stars. As ejected material rams into the nebula on the lower left, it takes on wider shapes, because there is more opportunity for the jets to interact with molecules within the nebula. Its material also causes the stars’ ejections to light up.

Over millions of years, the stars in Herbig-Haro 46/47 will fully form – clearing the scene.

Take a moment to linger on the background. A profusion of extremely distant galaxies dot Webb’s view. Its composite NIRCam (Near-Infrared Camera) image is made up of several exposures, highlighting distant galaxies and stars. Blue objects with diffraction spikes are stars, and the closer they are, the larger they appear. White-and-pink spiral galaxies sometimes appear larger than these stars, but are significantly father away. The tiniest red dots, Webb’s infrared specialty, are often the oldest, most distant galaxies.

NIRCam was built by a team at the University of Arizona and Lockheed Martin’s Advanced Technology Center.

Webb Space Telescope Photo Shows What Our Baby Sun Looked Like

NASA’s James Webb Space Telescope’s high resolution, near-infrared look at Herbig-Haro 211 reveals exquisite detail of the outflow of a young star, an infantile analogue of our Sun. Herbig-Haro objects are formed when stellar winds or jets of gas spewing from newborn stars form shock waves colliding with nearby gas and dust at high speeds

The image showcases a series of bow shocks to the southeast (lower-left) and northwest (upper-right) as well as the narrow bipolar jet that powers them in unprecedented detail. Molecules excited by the turbulent conditions, including molecular hydrogen, carbon monoxide and silicon monoxide, emit infrared light, collected by Webb, that map out the structure of the outflows.
