A 16-year study conducted by the STELLA observatory in Tenerife has unveiled unprecedented insights into the chaotic nature of star spot behavior on XX Trianguli. Using advanced robotic spectroscopy and Doppler imaging, researchers documented the star's surface evolution, showcasing a noncyclic dynamo mechanism fundamentally different from the Sun's. The findings are published in Nature Communic

SpaceX set a record for the most launches by a first-stage booster Wednesday morning when one of its Falcon 9 rockets lifted a new round of Starlink satellites into space. The Cape Canaveral Space Force Staton launch at 5:13 a.m., EDT from Florida was the 24th time the first stage was used. The booster landed safely on the drone ship A Shortfall of Gravitas roughly nine minutes after t

Dry river channels and lake beds on Mars point to the long-ago presence of a liquid on the planet's surface, and the minerals observed from orbit and from landers seem to many to prove that the liquid was ordinary water. Not so fast, the authors of a new Perspectives article in Nature Geoscience suggest. Water is only one of two possible liquids under what are

US President-elect Donald Trump on Wednesday nominated Jared Isaacman, a billionaire online payments entrepreneur and the first private astronaut to conduct a spacewalk, as the next head of NASA. The nod raises questions about potential conflicts of interest, given Isaacman's financial ties to SpaceX chief Elon Musk, who is set to co-lead a government efficiency commission and is one of Trum

Using the NASA/ESA/CSA James Webb Space Telescope, an international team of astronomers have found new galaxies in the Spiderweb protocluster. Their characteristics reveal that new galaxies are forming in these large cosmic cities, with the finding that gravitational interactions in these dense regions are not as important as previously thought.
