The Andromeda galaxy is surrounded by a constellation of dwarf galaxies that are arranged in a highly lopsided manner. Analysis of cosmological simulations published in Nature Astronomy reveal that this degree of asymmetry is only […]

Although we know that supermassive black holes (millions of times the mass of our sun) lurk at the center of most galaxies, their very nature makes them difficult to spot and study. In contrast to […]

Are we alone in the universe? The answer to one of humanity’s biggest questions is complicated by a basic reality: If there is life on other worlds, it may not look familiar. A sample of […]

Scientists with NASA’s Perseverance rover are exploring what they consider a veritable Martian cornucopia full of intriguing rocky outcrops on the rim of Jezero Crater. Studying rocks, boulders, and outcrops helps scientists understand the planet’s […]

Observations from NASA’s James Webb Space Telescope have provided a surprising twist in the narrative surrounding what is believed to be the first star observed in the act of swallowing a planet. The new findings, […]

A team led by Satoya Nakano and Kengo Tachihara at Nagoya University in Japan has revealed new insights into the motion of massive stars in the Small Magellanic Cloud (SMC), a small galaxy neighboring the […]

Astronomers have peered back in time to find what looks like a population of “hidden” galaxies that could hold the key to unlocking some of the universe’s secrets. If their existence is confirmed it would […]

Using NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR), Indian astronomers have performed X-ray observations of an X-ray binary designated 4U 1907+09. Results of the observational campaign, published April 3 on the arXiv preprint server, yield new […]

Researchers from the University of Waterloo have proposed a new method to measure the Hubble constant that could help resolve one of modern cosmology’s pressing puzzles: the Hubble tension.This post was originally published on this […]

A collaborative research team has improved visual localization and topographic mapping techniques that enable China’s Zhurong rover to navigate and conduct scientific investigations on Mars. These techniques played a crucial role in the success of […]
