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 two black holes that orbit each other (i.e., binary black holes).

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 swept around Mars’s surface.

When astronauts returned from NASA’s final Apollo moon mission in 1972, some of the samples they collected were sealed and carefully stored away in the hope that future researchers using advanced equipment might analyze them and make new discoveries.

Interstellar visitor 3I/ATLAS has been constantly changing as it makes its way through our solar system. That’s to be expected, as, for the first time in potentially billions of years, it’s getting close to the energy put out by a star.

An instrument is set to improve the detection and direct imaging of planets outside our solar system by harnessing the power of liquid crystals. The Programmable Liquid-crystal Active Coronagraphic Imager for the DAG telescope (PLACID) was installed earlier this year at the 4m-diameter telescope of the newly built Eastern Anatolian Observatory (DAG) observatory in Eastern […]
Spirals of solar wind can spin off larger solar eruptions and disrupt Earth’s magnetic field, yet they are too difficult to detect with our current single-location warning system, according to a new study from the University of Michigan.

Recently, NASA revealed exciting details of new findings from Mars. Scientists have discovered tiny patterns of unusual minerals in the clay-rich rocks on the edge of Jezero Crater—an ancient lake once fed by Martian river systems, and the exploration site of the NASA Perseverance Rover.

The Search for Extraterrestrial Intelligence (SETI) has a data scale problem. There are just too many places to look for an interstellar signal, and even if you’re looking in the right place you could be looking at the wrong frequency or at the wrong time. Several strategies have come up to narrow the search given […]
Astronomers from South Africa have conducted multi-band observations of a nearby dwarf irregular galaxy known as UGCA 320. Results of the observational campaign, recently published on the arXiv preprint server, yield important insights into the nature of this galaxy.

For decades, scientists engaged in the Search for Extraterrestrial Intelligence (SETI) have probed the galaxy for signs of artificial radio transmissions. Beginning with Project Ozma in 1960, astronomers have used radio antennas to listen for possible transmissions from other star systems or galaxies.

Scientists digging through data collected by the Cassini spacecraft have found new complex organic molecules spewing from Saturn’s moon Enceladus. This is a clear sign that complex chemical reactions are taking place within its underground ocean. Some of these reactions could be part of chains that lead to even more complex, potentially biologically relevant molecules. […]
Nobel laureate Dr. George Smoot, who conducted groundbreaking research into the origins of the universe during a long career at the University of California, Berkeley, and the Lawrence Berkeley National Laboratory, has died, the school said. He was 80.

Researchers from the Yunnan Observatories of the Chinese Academy of Sciences (CAS) have unveiled a neural network-based automated method for identifying heartbeat stars—a rare type of binary star system. Their findings are published in The Astronomical Journal.

The marimo (Aegagropila brownii), a nationally designated Special Natural Monument of Japan, inhabits Lake Akan in Hokkaido, where environmental conditions fluctuate drastically with the seasons. Of particular concern is the period immediately after ice melt in early spring, when low water temperatures coincide with strong sunlight, posing a risk of severe damage to photosynthetic activity. […]
In the 17th century, astronomers Christiaan Huygens and Giovanni Cassini trained their telescopes on Saturn and uncovered a startling truth: the planet’s luminous bands were not solid appendages, but vast, separate rings composed of countless nested arcs.
