James Webb Space Telescope (2 Viewers)

[Sailorsaint]

NASA released the first images from the James Webb space telescope in July and the spacecraft hasn’t stopped yet. On top of official image releases, the raw data captured by the telescope has yielded an amazing amount of material, too. One of the latest images comes to us from an astronomy graduate and it gives us a mesmerizing view of the Great Barred Spiral Galaxy.

The Great Barred Spiral Galaxy is more formally known as NGC 1365. It is located around 56 million light years away from Earth. The galaxy is a star-forming galaxy with an actively feeding supermassive black hole—one akin to our own Milky Way black hole.

The galaxy is also “face-on” towards Earth, which gives astronomers a perfect view of its double-barred structure.........

"Hundreds of gigabytes of raw data waiting to be processed" Awesome!

NASA’s James Webb Space Telescope has revealed astonishing new pictures of Jupiter.

The images show our near neighbourhood in precise detail, and scientists help that it could further reveal what is happening on the chaotic planet.

Its vast storms, swirling winds and blazing auroras are all visible in the image, which was taken from the telescope’s Near-Infrared Camera, or NIRCam.

That camera has three infrared filters that are able to showcase details of the planet. But it means that its images must be mapped into visible light, and the blue on the image is the shorter wavelengths...........

That bottom image looks like a bad 4K HDR file. I'll have to take a picture to show you guys but it's crazy how similar it is.

Came here to post exactly this! Those images are incredible.

the red spot looks quite sharp

hard to imagine a storm wider than our entire planet

Hasn’t the red spot been shrinking?

seems I recall reading it’s a lot smaller than it was 40-50 years ago

Nasa’s James Webb Space Telescope has detected carbon dioxide on an alien world, for the first time.

A team of more than 30 scientists analyzing the spectrum of the gas giant exoplanet Wasp 39b have reported finding a clear signal of an abundance of carbon dioxide in the planets atmosphere.

Previous studies by the Hubble and Spitzer Space Telescopes had detected water vapor, potassium and sodium in the exoplanet’s atmosphere, but this is the first time carbon dioxide — a green house gas and, at least on Earth, a product of animal metabolism — has been clearly identified on distant world……

Nasa’s Webb telescope finds gas on alien world for first ever time

The first clear detection of the green house gas carbon dioxide in a distant gas giant planet bodes well for future Webb telescope studies of rocky exoplanets more similar to Earth

That’s cool and all but Venus has a ton of CO2 and no life.

The James Webb Space Telescope, performing splendidly as it examines the universe, has got astronomers scratching their heads. The very distant universe looks a little different than expected.

The telescope, launched eight months ago and orbiting the sun about a million miles from Earth, has been capturing images of extremely faint galaxies that emitted their light in the first billion years or so after the big bang. Observing these “early” galaxies is one of the main missions of the telescope — to see deeper into space, and further back in time, than any previous telescope.

The first scientific results have emerged in recent weeks, and what the telescope has seen in deepest space is a little puzzling. Some of those distant galaxies are strikingly massive. A general assumption had been that early galaxies — which formed not long after the first stars ignited — would be relatively small and misshapen. Instead, some of them are big, bright and nicely structured.

“The models just don’t predict this,” Garth Illingworth, an astronomer at the University of California at Santa Cruz, said of the massive early galaxies. “How do you do this in the universe at such an early time? How do you form so many stars so quickly?”

This isn’t a cosmological crisis. What’s happening is a lot of fast science, conducted “in real time,” as astrophysicist Jeyhan Kartaltepe of the Rochester Institute of Technology puts it. Data from the new telescope is gushing forth, and she is among the legions of astronomers who are spinning out new papers, posting them quickly online in advance of peer review..........

The universe is massive, and Earth is located a long way away from the edge of our known universe. Putting that into a scale is difficult and doesn’t properly showcase just how big the universe is. However, when you start looking at a logarithmic view of the universe, it becomes easier to tell just how massive our universe is, and just how little we know about everything.

The map in question was created by Pablo Carlos Budassi. He shared an original version of the map back in 2012. However, he has updated his logarithmic view of the universe consistently over the years. In fact, it was recently highlighted as the Astronomy Photo of the Day, because it provides such a beautiful view of the universe and everything we know about it thus far.

Looking at a logarithmic view of the universe provides a perspective that a linear map just doesn’t offer. For a linear map, we’d need to take dozens of Earths to measure out distances. This would ultimately make it impossible to pay attention to the smaller parts of the image, while still appreciating the larger picture at play.

However, with a logarithmic map, we can view the universe from a multiplicative factor of “10”. Using a logarithmic scale, the Sun, Mercury, and Mars are all within the same area. We typically measure the universe in Astronomical Units (AU). One AU is equal to the distance from Earth to our Sun...........

Yeah the atmospheric clouds of sulfuric acid might be a bit of an issue there.

Also, I am not prepared to say Venus has no life... probable, no... but not impossible.

Where do I get that on a poster, or a shirt.

There’s plenty of examples of life here on Earth in environments that conventional wisdom says should be impossible

Exoplanets, worlds beyond our own Solar System, are a wild bunch: some are gas giants like Jupiter, but are scorching hot due to orbiting closer to their star than Mercury does the Sun, some are frozen hulks, while others may be water worlds covered entirely by ocean, and still others may sport clouds and rain of liquid gemstones.

And some of them, somewhere, could host life as we know. Or even as we don’t.

Scientists have discovered thousands of these worlds since the 1990s, and exoplanet science has already changed the yway scientists think about the universe, and our place within it.

But with the launch of the James Webb Space Telescope in December 2021, exoplanetary science stepped into a new era.

The Webb telescope sports new, sensitive instruments designed to work with the observatories uniquely powerful optics to peer deeply at exoplanets and decipher their secrets, characterizing the chemicals in their atmosphere to help chart their history and evolution, understand their present climates, and just maybe catch signs of biological activity. Alien life…..

Scientists will discover the weirdest planets thanks to Nasa’s Webb Telescope

After two decades of hunting for exoplanets, the James Webb Space Telescope is set to begin really exploring these strange new worlds
