Best of Last Week – Double Galaxy Mystery, Turning Books into Digital Art, Evidence of Team Brain State


This Hubble Space Telescope snapshot shows three magnified images of a distant galaxy embedded in a cluster of galaxies. These images are produced by a trick of nature called the gravitational lens. The immense gravity of the galaxy cluster amplifies and distorts the light of the distant galaxy behind it, creating multiple images. The galaxy cluster, cataloged as SDSS J223010.47-081017.8, is 7 billion light years from Earth. Hubble has observed many galaxies with gravitational lenses. However, the images spotted in this Hubble snapshot are unique. Two of the enlarged images, shown in the lower right pull-out, are exact copies of each other. The two shiny ovals are the nuclei of the galaxy. This rare phenomenon occurs because the background galaxy overlaps a ripple in the fabric of space. This “ripple” is an area of ​​greater magnification, caused by the gravity of dense amounts of dark matter, the invisible glue that makes up most of the mass of the universe. As light from the distant galaxy passes through the cluster along this ripple, two mirror images are produced, along with a third image that can be viewed from the side. A close-up of the third image is shown in the pull-out top right. This image most closely resembles the distant galaxy, located over 11 billion light years away. Based on a reconstruction of this image, the researchers determined that the distant galaxy appears as a barred spiral on the edge with blocky star formation in progress. The mirror images are named “Hamilton’s object” for the astronomer who discovered them. Credit: PRINCIPAL AUTHOR: NASA, ESA, Richard E.

It’s been a good week for space science as an international team of researchers discovered that an extreme exoplanet was even more exotic than originally thought – WASP-76b turned out to be hotter than expected. Plus, a “double” galaxy still mystifies Hubble astronomers after years of study. The light from two bright linear objects appear to be mirror images of the same object caused by a gravitational lens, making it difficult to discern the object’s true configuration. And two space scientists, Brett Gladman and Kathryn Volk from the University of British Columbia, performed simulations suggesting that a planet the size of Earth or Mars could be orbiting beyond Neptune. .

In tech news, a pair of researchers, Milan Janosov with Datapolis and famous digital artist Flora Borsi, have developed a way to produce digital art using data from published books. of the universe. Additionally, Bradley Lane, with the University of Kansas, found evidence showing that the energy revolution involving the transition from internal combustion vehicles to electric vehicles will be slow and difficult due to convenience concerns. And a combined team from the University of Heidelberg and the University of Bern developed a framework to enhance deep learning using doped neuromorphic substrates. Additionally, a team from the University of Helsinki used artificial intelligence to create a model capable of generating humorous versions of existing headlines.

In other news, a team from Rockefeller University found differences in long-term COVID antibodies that are created in the body as a result of vaccination rather than infection. They were less efficient at producing antibodies that keep reproducing over time. And an expert in medieval Latin literature has found evidence to suggest that Italian sailors knew America 150 years before Christopher Columbus set sail.

And finally, if you’ve ever worked with a group of individuals and felt the team was in some kind of “groove,” you might have been on to something. An international team of researchers have discovered the first neuroscientific evidence of team flow as a single brain state, which suggests that the brain waves of team members who work well together are synchronized.
