Building in Space With Laser "Origami"

University of Florida researchers are exploring how lasers could help astronauts build structures on the moon using materials already available there, including lunar soil transformed into glass. The work, led by Victoria M. Miller, Ph.D., an associate professor in the Herbert Wertheim College of Engineering and researcher with the UF Astraeus Space Institute, recently completed a research phase focused on laser forming, a manufacturing process that bends materials without physical contact. from Universe Today https://ift.tt/h4MKLHp via IFTTT

This is How Supermassive Black Holes Feed Themselves

Astronomers may have found the missing link in the SMBH feeding process. New observations with the JWST show that a galaxy's circumnuclear disk, which feeds gas into its black hole, is connected to a much larger network of filaments. Cool gas flows through these filaments into the SMBH's sphere of influence. from Universe Today https://ift.tt/mHUFA3h via IFTTT

Astronomers Find a Four-Carbon Sugar in Deep Space

The space between stars may seem like a barren desert, but over the past few decades scientists have been finding all sorts of interesting chemicals in it. From the precursors to proteins to the building blocks of cell membranes, there has been discovery after discovery of new molecules in the giant gas clouds between the stars. Now, a new paper available in pre-print on arXiv details the discovery of the first ever four-carbon sugar in the Interstellar Medium (ISM), and it is another brick on the path to understanding how life on Earth first developed. from Universe Today https://ift.tt/jZxCzAe via IFTTT

Orbiting Stars Give Clues to a Quiescent Black Hole's Mass

How do you measure the mass of a dormant black hole in the early Universe? That's a question astronomers at University College London (UCL) and Carnegie scientists wanted to answer about a distant object that is invisible. So, they turned to James Webb Space Telescope (JWST) studies of the region around the black hole to find that answer. from Universe Today https://ift.tt/M0aAPfX via IFTTT

Why Can't the Universe Be Cyclic? Part 4: When a Good Idea Meets Bad Data

The ekpyrotic universe is a beautiful idea that runs headlong into the data. From hand-waved singularities and assumed dark energy to the killer blow from Planck and WMAP measurements of the cosmic microwave background, here is why nature has so far voted against it. from Universe Today https://ift.tt/rZ7vRG9 via IFTTT
