Astronomers have witnessed for the first time a violent cosmic collision in which one galaxy pierces another with intense radiation. Their results, published today in Nature, show that this radiation dampens the wounded galaxy’s ability to form new stars. This new study combined observations from both the European Southern Observatory’s Very Large Telescope (ESO’s VLT) and the Atacama Large Millimeter/submillimeter Array (ALMA), revealing all the gory details of this galactic battle.

SAN ANTONIO — May 20, 2022 — Southwest Research Institute scientists have discovered how solar activity affects the velocity distribution and evolution of helium pickup ions.

The fundamental building blocks for planet formation can exist even in environments with extreme ultraviolet radiation, according to a new study by an international collaboration led by Penn State astronomers, using NASA's James Webb Space Telescope.

Achieved the first spectroscopic observation of hydrogen (H₂) and deuterium (D₂) molecules physically adsorbed within an atomic-scale space known as a picocavity.Employed picometric rotational/vibrational spectroscopy to elucidate their structure and dynamics at the single-molecule level.Observed distinct spectral responses for H₂ and D₂, and theoretically demonstrated that these differences arise from non-trivial isotope effects due to quantum nuclear effects.

This advancement in precision molecular spectroscopy within picocavities opens new possibilities for well-controlled studies of functional materials for energy applications, such as hydrogen storage systems and catalytic surfaces, as well as for developing single-molecule quantum control technologies.

In the intriguing realm of star-forming galaxies, the key factor isn't the total amount of gas but rather its strategic distribution within the galaxy.

Imagine drawing on something as delicate as a living cell — without damaging it. Researchers at the University of Missouri have made this groundbreaking discovery using an unexpected combination of tools: frozen ethanol, electron beams and purple-tinted microbes.

By advancing a method called ice lithography, the team was able to etch incredibly small, detailed patterns directly onto fragile biological surfaces.
