An international team of astronomers has used the Atacama Large Millimeter/submillimeter Array (ALMA) to observe a well-known quasar known as the Cloverleaf. As part of the observations, they serendipitously discovered a new ultra-luminous infrared galaxy. […]

A discovery of binary stars could be the first step in building a more complete picture of how our galaxy formed, according to astronomers from The Australian National University (ANU). The discovery is part of […]

The appearance of oxygen in Earth’s atmosphere was a turning point in the history of our planet, forever transforming the environment and setting the stage for complex life. This event, known as the Great Oxidation […]

For the first time, astronomers have managed to capture a radio image showing two black holes orbiting each other. The observation confirmed the existence of black hole pairs. In the past, astronomers have only managed […]

For decades, scientists have been curious about how much water Mars once had and what led to its gradual transformation into the dry planet we see today. A new study published online on September 2, […]

SXS—Simulating eXtreme Spacetimes—is an ongoing scientific collaboration that has been generating simulations of dramatic events in space, particularly mergers of binary black hole systems, for several decades. Recently, SXS published a paper describing version 3 […]

Using ESA’s XMM-Newton satellite, astronomers have conducted deep observations of a massive galaxy known as NGC 5746. As a result, they detected a hot gaseous outflow in the galaxy. The new findings, presented Oct. 1 […]

Gravitational waves are energy-carrying waves produced by the acceleration or disturbance of massive objects. These waves, which were first directly observed in 2015, are known to be produced during various cosmological phenomena, including mergers between […]

Combing through 20 years of images from the European Space Agency’s Mars Express and ExoMars Trace Gas Orbiter spacecraft, scientists have tracked 1,039 tornado-like whirlwinds to reveal how dust is lifted into the air and […]

Simulation results highlight how team composition shapes stress, health, performance, and cohesion in long-duration space missions, according to a study published October 8, 2025, in the open-access journal PLOS One by Iser Pena and Hao […]
