For the first time, astronomers have directly observed the rotation of a protoplanetary disk, capturing a sequence of images over four years that reveals the motion of gas and dust surrounding the young star AB Aurigae. The observations provide an unprecedented view of the environment where planets form......
The behavior of gravity remains consistent with predictions made by Isaac Newton and Albert Einstein even across vast cosmic distances, according to a study published in Physical Review Letters. The findings come from the largest test of gravitational strength ever conducted and reinforce the prevailing......
Astronomers have reconstructed the full 12 billion year history of a spiral galaxy for the first time, offering new insight into how galaxies form and evolve over cosmic time. The study, led by the Center for Astrophysics Harvard and Smithsonian and published in Nature Astronomy, focuses on the massive......
A new astronomical instrument under construction in the mountains of Chile is set to become the largest lens based telescope array ever built. Known as MOTHRA, the Modular Optical Telephoto Hyperspectral Robotic Array will combine 1,140 Canon telephoto lenses to observe extremely faint structures in......
Astronomers using the Atacama Large Millimeter Submillimeter Array have detected unusually high levels of methanol in the interstellar comet 3I/ATLAS, revealing a chemical composition rarely seen in comets formed within our solar system. The findings, reported by the National Radio Astronomy Observatory......
A European Space Agency spacecraft traveling toward Jupiter has captured detailed images of the interstellar comet 3I/ATLAS, revealing a bright coma and a long tail of gas and dust as the rare visitor speeds away from the solar system. The observations were made by the Jupiter Icy Moons Explorer mission,......
Interstellar comet 3I/ATLAS is now racing away from the inner solar system after a fleeting but revealing visit that has given astronomers fresh insight into the chemistry of deep space. The icy body is only the third confirmed object known to have entered our planetary neighborhood from another star......
Astronomers have uncovered one of the universe's earliest "dead" galaxies, where a supermassive black hole at its core halted star formation not through a dramatic outburst but via repeated cycles of gas heating and ejection a process likened to death by a thousand cuts. The study, published......
The Hubble Space Telescope has captured rare and detailed images of the interstellar comet 3I/ATLAS, revealing two opposing jets of gas and dust that alternate in brightness in a puzzling rhythmic pattern. This phenomenon, never before observed in such a form, has raised new questions about how interstellar......
Astronomers are preparing for a remarkable cosmic encounter as interstellar comet 3I/ATLAS makes its closest pass to Earth on December 19. The celestial visitor, originating from beyond the solar system, will come no nearer than 167 million miles from the planet roughly twice the distance between the......
The United Nations has confirmed that interstellar comet 3I/ATLAS is at the centre of a full scale planetary defence exercise designed to test how well the world can respond to a genuine cosmic threat in the future. Aimed at space policy analysts, planetary defence specialists and readers who follow......
Meriem El Yajouri, a celebrated Moroccan astrophysicist, has been appointed to NASA’s Space Telescope Science Institute (STScI) in Baltimore, the renowned center managing the scientific missions of the Hubble, James Webb, and upcoming Nancy Grace Roman Space Telescope. This achievement marks a......
The interstellar comet 3I/ATLAS, the third confirmed visitor from beyond our solar system, has astonished scientists with its unusually high levels of carbon dioxide and unexpected activity as it approaches the Sun. Multiple NASA missions and international observatories are closely studying its composition......
