White dwarfs are the compact remnants of stars that have stopped nuclear burning, a fate that will eventually befall our sun. These extremely dense objects are degenerate stars because their structure is counterintuitive: the heavier they are, the smaller they are. Go to Source A pair of Sydney Ph.D. students helped sharpen the view of humanity’s most powerful space observatory—without leaving Earth. As an indelible reminder of this thrilling result, Louis Desdoigts, now a postdoctoral researcher at Leiden in the Netherlands, and his colleague Max Charles, had tattoos of the instrument their work has repaired inked on their arms. […] Radio astronomy opens a window onto the invisible universe. While our eyes can detect visible light, countless objects in space emit radiation at much longer wavelengths, in the radio portion of the electromagnetic spectrum. Where visible light gets blocked by interstellar dust, radio waves pass through unrestricted, revealing objects that remain completely invisible to traditional […] Scientists at MIT and elsewhere have discovered extremely rare remnants of “proto Earth,” which formed about 4.5 billion years ago, before a colossal collision irreversibly altered the primitive planet’s composition and produced Earth as we know today. Their findings, reported today in the journal Nature Geosciences, will help scientists piece together the primordial starting ingredients […] 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 Chen of the Stevens Institute of Technology, U.S. In particular, team diversity in personality traits may contribute to greater resilience […] Duplicating expensive resources is expensive and wasteful, and most people would agree it’s unnecessary. However, the planned increase in major satellite constellations is currently causing a massive duplication of resources as individual companies and even countries try to set up their own infrastructure in space. Go to Source Astronomers have captured the clearest picture yet of how massive stars are born, revealing a dramatic interplay between gravity and magnetic fields in some of our galaxy’s most dynamic star forming regions. A team led by Dr. Qizhou Zhang from the Center for Astrophysics | Harvard & Smithsonian used the Atacama Large Millimeter/submillimeter Array (ALMA) […] 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). Go to Source 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. Go to Source 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. Go to Source 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. Go to Source 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 […] |
