Water is essential for life as we know it. However, scientists debate how it reached the Earth and whether the same processes could seed rocky exoplanets orbiting distant stars. New insights may come from the planetary system PDS 70, located 370 light-years away. The star hosts both an inner disk and outer disk of gas and dust, separated by a 5 billion-mile-wide (8 billion kilometer) gap, and within that gap are two known gas-giant planets.

The James Webb Space Telescope’s four scientific instruments are capable of examining the universe across a range of light called infrared, which is beyond the red end of the visible light rainbow (Webb also captures a little visible red as well). Infrared wavelengths are broken down into near-, mid-, and far-infrared ranges. Each instrument has unique features that allow astronomers to study a variety of astronomical objects in different ways.

 

The James Webb Space Telescope has detected the earliest-known carbon dust in a galaxy ever.

Using the powerful space telescope, a team of astronomers spotted signs of the element that forms the backbone of all life in ten different galaxies that existed as early as 1 billion years after the Big Bang.

The detection of carbon dust so soon after the Big Bang could shake up theories surrounding the chemical evolution of the universe. This is because the processes that create and disperse heavier elements like this should take longer to build up in galaxies than the age of these young galaxies at the time the James Webb Space Telescope (JWST) sees them.

Using the James Webb Space Telescope (JWST), an international team of astronomers has found compelling evidence that early galaxies were responsible for the reionization of the early universe. This is the process by which neutral hydrogen atoms are ionized, making the universe transparent to light at wavelengths that would have been absorbed by the atoms. The research was done by members of the EIGER collaboration, which is using the JWST’s Near Infrared Camera (NIRCam) to study light from quasars in the early universe.

NASA’s James Webb Space Telescope has delivered the deepest and sharpest infrared image of the distant universe so far. Webb’s First Deep Field is galaxy cluster SMACS 0723, and it is teeming with thousands of galaxies – including the faintest objects ever observed in the infrared.

The peculiar galaxy NGC 3256 dominates this image from the James Webb Space Telescope. This Milky Way-sized galaxy lies about 120 million light-years away in the constellation Vela, and is a denizen of the Hydra-Centaurus Supercluster.

Cheers to our first year!

Let’s celebrate one year of Webb science by taking a brand-new look at Sun-like stars being born in this detailed close-up of Rho Ophiuchi, the closest-star-forming region to Earth. Webb spotted around 50 young stars, many close in mass to our star, giving us a glimpse into the early life of the Sun. Dark, dense dust cocoons still-forming protostars, while an emerging stellar newborn (top center) shoots out two huge jets of molecular hydrogen.

Hidden in the neck of this “hourglass” of light are the very beginnings of a new star — a protostar. The clouds of dust and gas within this region are only visible in infrared light, the wavelengths that Webb specializes in.

Some great battles in that race. Very enjoyable.

RIP Alpine

 

A stunning smash-up of two spiral galaxies shines in infrared with the light of more than a trillion suns. Collectively called Arp 220, the colliding galaxies ignited a tremendous burst of star birth. Each of the combining galactic cores is encircled by a rotating, star-forming ring blasting out the glaring light that Webb captured in infrared. This brilliant light creates a prominent, spiked, starburst feature. Credits: NASA, ESA, CSA, STScI, Alyssa Pagan (STScI)

Let's hope it doesn't have a RAM issue.

Hurhur.

To start, and have people engage in a discussion.

Truth. Just a few more weeks before we start getting the "Experts say the WORST winter an hundred years is predicted." ~~headlines~~ bullshit

I'm a RIF Refugee, and I was just recommended Connect for Lemmy, and I'm using it right now. It's on the Play store.

[–] [email protected] 1 points 2 years ago

Ah that's good there are things coming! Looking forward to what the devs can do.

I'll keep a look out! Thanks.

[–] [email protected] 1 points 2 years ago (7 children)

Just made my account too. RIP RIF, you were good to me.

Now I'm excited to see what this Lemmy.world is all about - does it have an app on the Play store?
