Physicists answer question of Supergalactic Plane’s absent spiral galaxies
Artist concept of the Milky Way. Credit: NASA/JPL-Caltech. Astrophysicists say they have found an answer to why spiral galaxies like our own Milky Way are largely missing from a part of our local universe called the Supergalactic Plane. The Supergalactic Plane is an enormous, flattened structure extending nearly a billion light years across in which…

Hot and heavy: New study of ‘teenage galaxies’ yields some surprises
Astronomers were surprised to see evidence of notoriously hard-to-detect elements like oxygen and nickel using observations of adolescent galaxies from the James Webb Telescope. (CN) — Why do different galaxies look so different? Why do they have different temperatures and different shapes? What happens to them along the way to make them like that? And,…

‘Teenage galaxies’ are unusually hot, glowing with unexpected elements
image: Light from 23 distant galaxies, identified with red rectangles in the Hubble Space Telescope image at the top, were combined to capture incredibly faint emission from eight different elements, which are labelled in the JWST spectrum at the bottom.Although scientists regularly find these elements on Earth, astronomers rarely, if ever, observe many of them in…

Axiom Space astronaut Marcus Wandt says space is ‘more real’ thanks to private flights
An astronaut from a new class of European spaceflyers says he’s ready to take flight. Marcus Wandt is a “project astronaut” from Sweden with the European Space Agency (ESA). Just a year ago, he was essentially put on call for some future spaceflight after his selection. Now space is “more real,” Wandt said in a…

A moon helps to uncover strange solar system body Eris
Artist’s impression of the dwarf planet Eris. Credit: ESO/L.Calçada and Nick Risinger Two nearly-identically sized worlds — Eris and Pluto — float distantly in the same frozen region of our outer solar system. A NASA spacecraft has visited Pluto, but not Eris, and each is so distant that it’s hard to study by telescope. So,…

Emirati university signs up to China’s moon base project
HELSINKI — China has added a United Arab Emirates’ university to its list of partners for the country’s moon base ambitions. A Memorandum of Understanding between the Deep Space Exploration Laboratory (DSEL) and the University of Sharjah (UoS), United Arab Emirates (UAE), on cooperation on the International Lunar Research Station (ILRS) was signed Nov. 14,…

More Evidence That Planets Orbiting M Dwarf Stars Are Uninhabitable
One of NASA’s greatest and most public goals is to find habitable planets orbiting stars other than the Sun. The stars NASA has identified as the most promising candidates for habitability are M dwarfs, also known as red dwarfs. These stars are less than half the Sun’s mass, less than a fifteenth of the Sun’s…
