Astronomers from Durham University propose the Milky Way's orientation was flipped over 90 degrees about 10 billion years ago due to a direct collision with the dwarf galaxy Gaia Sausage, a cosmic event simulated using supercomputers.
Astronomers found evidence that the Milky Way's disc was flipped over 90 degrees about 10 billion years ago after a head-on collision with a dwarf galaxy called the Gaia Sausage, long before the solar system formed. Supercomputer simulations by Durham University researchers explain the slow rotation of stars in the Milky Way's halo.
Astronomers have detected erythrulose, a four-carbon sugar, in a giant molecular cloud near the Milky Way's center, marking the first such discovery in interstellar space. This finding offers new insights into the formation and distribution of life's building blocks, suggesting similar chemical processes may occur on distant planets and altering theories on complex organic molecule formation.
A new study suggests that some of the coldest objects in the Milky Way, currently classified as stars, might be alien megastructures. Astrophysicist Amirnezam Amiri proposes these could be Dyson swarms, engineered systems harvesting stellar energy and releasing infrared heat, offering a new method to detect them.
Researchers identified the source of mysterious repeating radio signals from space. A global map of the fungal network supporting plant life and climate regulation was created. The Euclid space telescope captured a detailed image of the Milky Way's center. A new fossil axolotl species was found in Mexico. Earthquakes in Mexico, Norway, and Venezuela were documented, with seismic activity linked to sports victories and seismic doublets. Satellite imagery revealed the impact of Venezuelan earthquakes and how space lasers can track crustal shifts.
The ESA's Euclid space telescope has captured the largest and most detailed visible-light image of the Milky Way's galactic bulge, containing over 60 million stars, to aid in exoplanet detection and mass measurement via microlensing.
The European Space Agency's Euclid telescope captured a bright image of the Milky Way's galactic bulge, providing crucial context for NASA's upcoming Nancy Grace Roman Space Telescope mission, which will chart stellar changes and identify cosmic objects.
Astronomers using the James Webb Space Telescope have confirmed that Terzan 5, located in the Milky Way's bulge, is not a globular star cluster but a 'bulge fossil fragment.' It has undergone at least four distinct star formation phases, offering new insights into galactic history.
미국 연구팀이 우리은하 중심 블랙홀 궁수자리 A* 주변에서 3광년 길이의 원뿔형 빈 공간을 발견했다. 이는 블랙홀이 뜨거운 바람을 내뿜고 있다는 강력한 증거로, 50여 년간의 천문학계 수수께끼를 해결할 것으로 기대된다.
Scientists have discovered a giant, diagonally oriented magnetic twist deep within the Milky Way's Sagittarius Arm. This unusual structure, revealed through new radio observations and Faraday rotation analysis, challenges current models of galactic magnetic fields and suggests complex, long-term evolutionary processes.
Super-Earths, planets 1-4 times Earth's size, are the most common type of planet in the Milky Way, according to NASA's Kepler mission observations. These planets, which vary from rocky to gaseous compositions, form efficiently in protoplanetary discs but rarely grow large enough to become gas giants. Scientists estimate most stars host at least one planet of this size, making them far more prevalent than Earth-like planets in our galaxy. The James Webb Space Telescope is now being used to study their atmospheres for potential signs of life.
