New Webb image reveals dusty disk like never seen before      (via sciencedaily.com) 

NASA's James Webb Space Telescope has imaged the inner workings of a dusty disk surrounding a nearby red dwarf star. These observations represent the first time the previously known disk has been imaged at these infrared wavelengths of light. They also provide clues to the composition of the disk.

NASA's Webb confirms its first exoplanet      (via sciencedaily.com) 

Researchers confirmed an exoplanet, a planet that orbits another star, using NASA's James Webb Space Telescope for the first time. Formally classified as LHS 475 b, the planet is almost exactly the same size as our own, clocking in at 99% of Earth's diameter.

Scientists study life origins by simulating a cosmic evolution      (via sciencedaily.com) 

Amino acids make up millions of proteins that drive the chemical gears of life, including essential bodily functions in animals. Because of amino acids' relationship to living things scientists are eager to understand the origins of these molecules. After all, amino acids may have helped spawn life on Earth after being delivered here about 4 billion years ago by pieces of asteroids or comets.

The seven-year photobomb: Distant star's dimming was likely a 'dusty' companion getting in the way, astronomers say      (via sciencedaily.com) 

Astronomers were on the lookout for 'stars behaving strangely' when an automated alert from pointed them to Gaia17bpp, a star that had gradually brightened over a 2 1/2-year period. But follow-up analyses indicated that Gaia17bpp wasn't changing. Instead, the star is likely part of a rare type of binary system. Its apparent brightening was the end of a years-long eclipse by an unusual, 'dusty' stellar companion.

Planetary system's second Earth-size world discovered      (via sciencedaily.com) 

Using data from NASA's Transiting Exoplanet Survey Satellite, scientists have identified an Earth-size world, called TOI 700 e, orbiting within the habitable zone of its star -- the range of distances where liquid water could occur on a planet's surface. The world is 95% Earth's size and likely rocky.

Scientists find evidence for magnetic reconnection between Ganymede and Jupiter      (via sciencedaily.com) 

In June 2021, NASA's Juno spacecraft flew close to Ganymede, Jupiter's largest moon, observing evidence of magnetic reconnection. A team has used Juno data to examine the electron and ion particles and magnetic fields as the magnetic field lines of Jupiter and Ganymede merged, snapped and reoriented, heating and accelerating the charged particles in the region.

Hydrogen masers reveal new secrets of a massive star      (via sciencedaily.com) 

While using the Atacama Large Millimeter/submillimeter Array (ALMA) to study the masers around oddball star MWC 349A scientists discovered something unexpected: a previously unseen jet of material launching from the star's gas disk at impossibly high speeds. What's more, they believe the jet is caused by strong magnetic forces surrounding the star. The discovery could help researchers to understand the nature and evolution of massive stars and how hydrogen masers are formed in space.

The world's largest turbulence simulation unmasks the flow of energy in astrophysical plasmas      (via sciencedaily.com) 

Researchers uncover the long-hidden process that helps explain why the Sun's corona can be vastly hotter than the solar surface that emits it.

Experimentalists: Sorry, no oxygen required to make these minerals on Mars      (via sciencedaily.com) 

When NASA's Mars rovers found manganese oxides in rocks in the Gale and Endeavor craters on Mars in 2014, the discovery sparked some scientists to suggest that the red planet might have once had more oxygen in its atmosphere billions of years ago. But a new experimental study upends this view. Scientists discovered that under Mars-like conditions, manganese oxides can be readily formed without atmospheric oxygen.

Ancient asteroid grains provide insight into the evolution of our solar system      (via sciencedaily.com) 

The UK's national synchrotron facility, Diamond Light Source, was used by a large, international collaboration to study grains collected from a near-Earth asteroid to further our understanding of the evolution of our solar system. Researchers brought a fragment of the Ryugu asteroid to Diamond's Nanoprobe beamline I14 where a special technique called X-ray Absorption Near Edge Spectroscopy (XANES) was used to map out the chemical states of the elements within the asteroid material, to examine its composition in fine detail.

Marsquake!      (via sciencedaily.com) 

The quake lasted four hours and identified layering in the crust that could indicate a meteoroid impact. The 4.7 magnitude temblor happened in May 2022 and released five times more energy than any previously recorded quake on Mars. Mapping the seismic activity on Mars will help inform scientists where and how to build structures to ensure the safety of future human explorers.

Astronomers find that two exoplanets may be mostly water      (via sciencedaily.com) 

Astronomers have found evidence that two exoplanets orbiting a red dwarf star are 'water worlds,' planets where water makes up a large fraction of the volume.

Exquisite views of distant galaxies      (via sciencedaily.com)     Original source 

For decades, the Hubble Space Telescope provided us with the most spectacular images of galaxies. This all changed when the James Webb Space Telescope (JWST) launched and successfully completed commissioning. For astronomers, the universe is now revealed in a new way never imagined by the telescope's Near-Infrared Camera (NIRCam) instrument.
