Billions of celestial objects revealed in gargantuan survey of the Milky Way      (via sciencedaily.com)     Original source 

Astronomers have released a gargantuan survey of the galactic plane of the Milky Way. The new dataset contains a staggering 3.32 billion celestial objects -- arguably the largest such catalog so far. The data for this unprecedented survey were taken with the Dark Energy Camera.

How was the solar system formed? The Ryugu asteroid is helping us learn      (via sciencedaily.com)     Original source 

Our solar system is estimated to be about 4.57 billion years old. Previous analyses of ancient meteorites have shown that minerals were created through chemical reactions with water as far back as 4.5 billion years ago. New findings from the Ryugu asteroid samples indicate that carbonates were forming from water-rock reactions several million years earlier, even closer to the solar system's beginnings.

The rich meteorology of Mars studied in detail from the Perseverance rover      (via sciencedaily.com) 

Perseverance has now completed its investigation of the atmosphere throughout the first Martian year (which lasts approximately two Earth years). Specifically, astronomers have studied seasonal and daily cycles of temperature and pressure, as well as their significant variations on other time scales resulting from very different processes.

New small laser device can help detect signs of life on other planets      (via sciencedaily.com) 

As space missions delve deeper into the outer solar system, the need for more compact, resource-conserving and accurate analytical tools has become increasingly critical -- especially as the hunt for extraterrestrial life and habitable planets or moons continues. A University of Maryland-led team developed a new instrument specifically tailored to the needs of NASA space missions. Their mini laser-sourced analyzer is significantly smaller and more resource efficient than its predecessors--all without compromising the quality of its ability to analyze planetary material samples and potential biological activity onsite.

Researchers measure size-luminosity relation of galaxies less than a billion years after Big Bang      (via sciencedaily.com) 

A team has studied the relation between galaxy size and luminosity of some of the earliest galaxies in the universe taken by the James Webb Space Telescope, less than a billion years after the Big Bang.

Hubble finds hungry black hole twisting captured star into donut shape      (via sciencedaily.com) 

Black holes are gatherers, not hunters. They lie in wait until a hapless star wanders by. When the star gets close enough, the black hole's gravitational grasp violently rips it apart and sloppily devours its gasses while belching out intense radiation. Astronomers have recorded a star's final moments in detail as it gets gobbled up by a black hole.

How did the Butterfly Nebula get its wings? It's complicated      (via sciencedaily.com) 

Something is amiss in the Butterfly Nebula. When astronomers compared two exposures of this planetary nebula that had been taken by the Hubble Space Telescope in 2009 and 2020, they saw dramatic changes in the material within its 'wings.' Powerful winds are apparently driving complex alterations of material within the Butterfly Nebula, behavior not seen in planetary nebulae to date. The researchers want to understand how such activity is possible from what should be a 'sputtering, largely moribund star with no remaining fuel.'

Old and new stars paint very different pictures of the Triangulum Galaxy      (via sciencedaily.com) 

Scientists have reported something unexpected about the distinct populations of stars that make up the Triangulum galaxy: In this satellite galaxy, a close companion of the much larger Andromeda galaxy, old and new stars occur in separate parts of the galaxy's structure, something not seen in galaxies like our own and so far not reporter for other satellite galaxies.

NASA's Webb uncovers star formation in cluster's dusty ribbons      (via sciencedaily.com) 

NGC 346, one of the most dynamic star-forming regions in nearby galaxies, is full of mystery. Now, it is less mysterious with new findings from NASA's James Webb Space Telescope.

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.

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.

Wide diversity of galaxies in the early universe      (via sciencedaily.com) 

New data have revealed that the structures of galaxies in the early universe were much more diverse and mature than previously known. JWST's ability to see faint high redshift galaxies in sharper detail than Hubble allowed the team of researchers to resolve more features and see a wide mix of galaxies.

Astronomers find the most distant stars in our galaxy halfway to Andromeda      (via sciencedaily.com) 

Astronomers have discovered more than 200 distant variable stars known as RR Lyrae stars in the Milky Way's stellar halo. The most distant of these stars is more than a million light years from Earth, almost half the distance to our neighboring galaxy, Andromeda, which is about 2.5 million light years away.

Scientists find pair of black holes dining together in nearby galaxy merger      (via sciencedaily.com) 

While studying a nearby pair of merging galaxies scientists have discovered two supermassive black holes growing simultaneously near the center of the newly coalescing galaxy. These super-hungry giants are the closest together that scientists have ever observed in multiple wavelengths. What's more, the new research reveals that binary black holes and the galaxy mergers that create them may be surprisingly commonplace in the Universe.
