Star Formation in the Center of the Milky Way Started at the Core and Then Worked its way out

One of the biggest questions facing astronomers today concerns star formation and its role in the evolution of galaxies. In particular, astronomers are curious whether the process began in the central regions of galaxies, where stars are more tightly bound. Previous observations have shown that numerous galaxies experienced intense periods of star formation in their … Read more

Revealed missing step in lipid formation could enable detection of past climates

A team from Penn State and the University of Illinois Urbana-Champaign has determined the missing step in the formation of a molecule called GDGT, which is a promising candidate for use as an indicator of past climate. The team determined the X-ray crystal structure of an enzyme that facilitates this process called GDGT/MAS—shown here bound … Read more

Influence of nanoparticles, surrounding ions on formation of β-sheet structure in amyloid β proteins

Infrared (FT-IR) spectra and β-sheet ratio of Aβ peptides interacting with CeF3 NPs. The effect of CeF3 nanoparticles on amyloid beta protein structure is measured directly with FT-IR spectroscopy. The formation of secondary structure shows up as a feature in the IR spectrum. Credit: Masakazu Umezawa / Tokyo University of Science, License type: CC BY … Read more

To find a planet, look for the signatures of planet formation — ScienceDaily

Finding forming planets is a tough but important job for astronomers: Only three planets have ever been discovered in the process of forming, and the most recent of these was found just weeks ago. Evan Rich, a postdoctoral researcher at the University of Michigan, suggests that instead of looking for individual planets forming, astronomers might … Read more

Scientists on the hunt for planetary formation fossils reveal unexpected eccentricities in nearby debris disk

Artist’s impression of the billion-year-old Sun-like star, HD 53143, and its highly eccentric debris disk. The star and a second inner disk are shown near the southern foci of the elliptical debris disk. A planet, which scientists assume is shaping the disk through gravitational force, is shown to the north. Debris disks are the fossils … Read more

A team of scientists undertake a comprehensive analysis of samples returned from the Japan Aerospace Exploration Agency’s Hayabusa2 mission and provide invaluable insights into the formation and evolution of our solar system — ScienceDaily

The Japan Aerospace Exploration Agency’s Hayabusa2 mission returned uncontaminated primitive asteroid samples to Earth. A comprehensive analysis of 16 particles from the asteroid Ryugu revealed many insights into the processes that operated before, during and after the formation of the solar system, with some still shaping the surface of the present-day asteroid. Elemental and isotopic … Read more

3D reconstruction reveals star formation activities of two dust clouds

The shape of the California and Orion A Clouds from two different perspectives at a spatial resolution of 15 light-years. The colors indicate density, with red colors representing higher values. The images are based on the 3D reconstruction by Sara Rezaei Khoshbakht and Jouni Kainulainen. Credit: Rezaei Khoshbakht & Kainulainen (2022) / MPIA Using tens … Read more

New research provides possible insights into the formation of Earth

Credit: CC0 Public Domain A new study, conducted by scientists at The University of New Mexico, found ancient, primordial helium-3 leaking from the Earth’s core, suggesting the planet formed inside a solar nebula, stirring further debate among scientists. Each year, about 2 kg of the rare isotope gas helium-3 escapes from Earth’s interior, mostly along … Read more
