DALLAS (AP) — NASA’s Webb Space Telescope has revealed the sharpest images yet of a portion of a horse-shaped nebula, showing the “mane” in finer detail.

The Horsehead Nebula, in the constellation Orion, is 1,300 light-years away. A light-year is nearly 6 trillion miles (9.7 trillion kilometers).

Discovered over a century ago, its nickname derives from its striking appearance — a wispy pillar of gas and dust that resembles a horse rearing its head.

Webb’s latest infrared images released Monday captured the top of Horsehead in greater detail, illuminating clouds of chilly hydrogen molecules and soot-like chemicals. These glamour shots can help refine astronomers’ understanding of the nebula, which acts as a nursery for big stars to brew.…..

Scientists using Nasa’s Webb telescope have found an icy “super-Earth” that could be home to alien life.

When researchers first discovered the planet, known as LHS 1140 b, they thought it might be like a very small version of a gaseous neighbour Neptune.

But new research using Nasa data has shown that it may have an atmosphere and perhaps even liquid water. That could make it one of the more promising places to search for alien life, the researchers suggest.

LHS 1140 b orbits around a low-mass red dwarf star that is about a fifth the size of our own Sun. It is exciting to scientists because they believe it could be in the “Goldilocks’ Zone”, where it is neither too close or too far from its star and thus might have liquid water.……

It occurs to me that aliens could have looked at Earth any number of times and dismissed us because we were in the middle of an Extinction Event.

We might be 400 million years behind the Fermi Paradox.

We can't locate aliens because they all ascended 300 million years ago.

So cool!
Looks a lot like a bird sticking its head out of a hole in a tree.

If the pairing doesn't have a name yet, it should be named Tsurukansa, after the Japanese, or just Golden Crane.

JWST spots six new ‘rogue worlds,’ neither planet nor star

In the quest to understand the universe’s many mysteries, astronomers are looking for potentially trillions of elusive space objects called rogue worlds. These stellar objects blur the lines between planet and star–to better understand the cosmic processes that form both. A team of astronomers...

For a galaxy at its age, Pablo's Galaxy is massive. Formed during an early period in the universe's history and officially known as GS-10578, Pablo's Galaxy received its nickname from a scientist who observed it in detail and noted its immense size: Its total mass is about 200 billion times the mass of our Sun.

Yet like a spiraling whirlpool, a black hole is currently removing so much gas from Pablo's Galaxy that it can no longer normally form stars. Thanks to the James Webb Space Telescope (JWST), University of Cambridge researchers led a study in the journal Nature Astronomy revealing the exact amount of gas being uncontrollably pulled into the celestial abyss by the black hole's gravity.

"Even though everyone was expecting black holes to starve galaxies by heating or removing gas, measurements showed that the amount of gas we could see being removed was simply not enough," Francesco D'Eugenio, an astronomer at the University of Cambridge's Kavli Institute for Cosmology, told Salon. "But before JWST, we could only see the hot, thin gas that shines most brightly. It turns out most of the gas being removed may be colder and harder to see."

D'Eugenio added, "JWST is so extraordinarily sensitive that we can observe much colder gas than with other telescopes." Detecting gases that had previously been too dark for them to identify and study, the scientists "measured how much gas is being removed from the galaxy, and how fast it is moving; the numbers show clearly that the amount of gas is sufficient to disrupt the normal star-forming activity of this galaxy."

In explaining a great deal about galaxy formation, the new study also raises provocative questions. Cosmologists believe the early universe was teeming with galaxies — perhaps even some filled with alien life. But clearly it didn't take long (on cosmic timescales, at least) for some galaxies to reach the end of their life. Pablo's Galaxy stands out for being dormant despite its large size and advanced age...............

 
In a pocket of the universe teeming with galaxies, the James Webb Space Telescope has zeroed in on one blazing so brightly it outshines its stars.

The James Webb Space Telescope has spotted the galaxy named GS-NDG-9422 — a realm that existed about one billion years after the Big Bang, and indeed one that may provide the missing link of galaxy evolution between the universe's first stars and well-structured galaxies.

GS-NDG-9422 "will help us understand how the cosmic story began," Alex Cameron, an observational astronomer at the University of Oxford in the U.K., said in a recent news release. "My first thought in looking at the galaxy's spectrum was, 'that's weird,' which is exactly what the Webb telescope was designed to reveal."

The newfound galaxy is inconspicuous — except for its unique light signature, which includes patterns astronomers haven't seen before. Those features, which contribute to the light seen by Webb, are best explained by the galaxy's superheated gas, rather than its stars, according to a paper published by Cameron and his colleagues in June in the journal Monthly Notices of the Royal Astronomical Society.

Computer models of gas clouds that are so heated by hot and massive stars to the point that their stars outshine their cosmic birthplaces were "nearly a perfect match to Webb's observations," according to the release. The newfound galaxy appears to be in the midst of a star-birth sprint, and its reservoirs of gas and dust are being pummeled with countless photons of light. It is this light the JWST has managed to see.

The telescope's data about GS-NDG-9422 suggests its stars "must be much hotter and more massive than what we see in the local universe," said study co-author Harley Katz, who is an assistant professor of astronomy and astrophysics at the University of Chicago. "Makes sense because the early universe was a very different environment."

The stars' temperatures exceed 140,000 degrees Fahrenheit (80,000 degrees Celsius), which is about twice the expected temperature for typical hot and massive stars, the new study found.............

Using the James Webb Space Telescope (JWST), astronomers have discovered that a "puffy" planet is asymmetric, meaning there is a significant difference between one side of the atmosphere and the other.

The extrasolar planet or "exoplanet" in question is WASP-107 b, which orbits an orange star smaller than the sun located around 210 light-years away. Discovered in 2017, WASP-107 b is 94% the size of Jupiter but only has 10% of the mass of the solar system gas giant. This means it is one of the least dense exoplanets ever discovered, far "puffier" than expected.

Earlier this year, scientists determined this is likely the result of the interior of WASP-107 b being much hotter than predicted, and the planet is also thought to possess a rocky core that is larger than what was previously modeled. These strange characteristics were explained by a scarcity of methane in its atmosphere. Now, scientists have another WASP-107 b mystery to solve.

The curious asymmetry of WASP-107 b presents astronomers with a conundrum. "This is the first time the east-west asymmetry of any exoplanet has ever been observed from space as it transits its star," Matthew Murphy, a graduate student at the University of Arizona's Steward Observatory, said in a statement.

Murphy and colleagues studied WASP-107 by recording light from its host star as it passed through the atmosphere of the planet as it crossed or "transited" the face of its star. "A transit is when a planet passes in front of its star — like the moon does during a solar eclipse," Murphy said, adding that "observations made from space have a lot of different advantages versus observations that are made from the ground."

WASP-107 b orbits its star at a distance of around 5 million miles, or about 6% of the distance between Earth and the sun. This means that the planet completes an orbit in around five Earth days. In addition, the exoplanet is tidally locked to its star. This results in one side, the "dayside," permanently facing the star, while the other, the "nightside," faces out to space in perpetuity...............

James Webb Space Telescope finds 'puffball' exoplanet is uniquely lopsided

"We don't have anything like it in our own solar system. It is unique, even among the exoplanet population."
