Technische Universität Ilmenau (Germany) is using artificial intelligence to improve the detection and classification of unidentified phenomena in the night sky. The research team of the group for data-intensive systems and visualization collaborated with the American Meteor Society, which initiated the AllSky7, an international network of scientists and amateur astronomers that permanently observes the night sky with specially designed cameras and classifies and assigns all events...

A new study could lead to ongoing health monitoring of astronauts to assess possible health risks and prevent disease progression. Astronauts are at higher risk for developing mutations – possibly linked to spaceflight – that can increase the risk of developing cancer and heart disease during their lifetimes, according to a first-of-its kind study from the Icahn School of Medicine at Mount Sinai.

A team of researchers collected blood samples from National Aeronautics and Space Administration (NASA) astronauts who flew space shuttle missions between 1998 and 2001. They discovered DNA mutations, known as somatic mutations, in the blood-forming system (hematopoietic stem cells) in all 14 astronauts studied...

Researchers at Osaka Metropolitan University have observed “baby stars” in the Small Magellanic Cloud, having an environment similar to the early universe. Toward one of the baby stars, they found molecular outflow, which has similar properties to those seen in the Milky Way galaxy, giving a new perspective on the birth of stars.

The heavy elements in interstellar matter significantly impact the mechanism of star formation. In the early universe, the abundance of heavy elements was lower than in the present universe because there was not enough time for nucleosynthesis to produce heavy elements in stars. It has not been well understood how star formation in such an environment differs from present-day star formation.

An international team led by Professor Toshikazu Onishi, Osaka...

The James Webb space telescope has revealed dazzling new detail of a previously known slice of the cosmos 32 million light-years away, in a new picture released by NASA and the European Space Agency (ESA).

The infrared technology of the telescope, launched in December 2021, has allowed for an even clearer view of the so-called Phantom Galaxy than astronomers had ever seen before.

“Webb’s sharp vision has revealed delicate filaments of gas and dust in the grandiose spiral arms which wind outwards from the center of this image,” NASA and the ESA said Monday.

“A lack of gas in the nuclear region also provides an unobscured view of the nuclear sta...
