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. Go to Source 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. Go to Source 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. Go to Source 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. Go to Source 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. Go to Source 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. Go to Source 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. Go to Source Billions of years ago, water flowed across Mars. Most scientists agree the red planet had rivers. But did those rivers flow into an ocean? New research from the University of Arkansas found strong evidence in Mars’ geology of an ocean in the planet’s northern hemisphere. Go to Source Whether an asteroid is spinning neatly on its axis or tumbling chaotically, and how fast it is doing so, has been shown to be dependent on how frequently it has experienced collisions. The findings, presented at the recent EPSC-DPS2025 Joint Meeting in Helsinki, are based on data from the European Space Agency’s Gaia mission and […] What new methods can be employed to help astronomers distinguish the light from an exoplanet and its host star so the former’s atmosphere can be better explored? This is what a recent study accepted to Astronomy & Astrophysics and currently available on the arXiv preprint server hopes to address as an international team of researchers […] Johns Hopkins applied mathematicians and astronomers have developed a new method to render images from ground-based telescopes as clear as those taken from space, a process that stands to expand the benefits of Earth-based instruments.
