The rotor blades that will carry NASA’s next-generation helicopters to new Martian heights broke the sound barrier during March tests at NASA’s Jet Propulsion Laboratory in Southern California. Data from the tests, which took place in a special chamber that can simulate environmental conditions on the Red Planet, indicate that the fastest traveling part of […] The most massive black holes in the universe detected by the ripples they make in spacetime were not born directly from collapsing stars, according to a new study. These cosmic giants instead build up through a series of repeated and extremely violent collision events in very densely populated star clusters, an international team of researchers […] Earth’s earliest continents may have set the chemical stage for life by regulating boron levels in ancient oceans, a new study in Terra Nova suggests. Go to Source Astronomers have long known that neutron stars, the crushed cores left behind after massive stars explode, should be scattered throughout the Milky Way galaxy. However, most of them are effectively invisible. A new study published in Astronomy & Astrophysics suggests that NASA’s upcoming Nancy Grace Roman Space Telescope could spot them anyway. Go to Source […] Supermassive black holes lurk at the centers of massive galaxies, including our own Milky Way. Puzzlingly, supermassive black holes more than a billion times the mass of the sun appear to exist just a few hundred million years after the Big Bang, when the universe was less than 5% of its current age. As interstellar […] An international team led by researchers at the Institute of Cosmos Sciences of the University of Barcelona (ICCUB) has developed a new method that could significantly improve our understanding of the expansion of the universe and the nature of dark energy. Go to Source In-situ Resource Utilization (ISRU) is our best bet for “living off the land” for a future Martian base, but tracking down those resources is no easy task. As of now, we have two options—send a rover to a specific location to scout it, or monitor it from orbit. Since rovers are expensive, and there are […] Astronomers from the South African Astronomical Observatory (SAAO) and elsewhere have conducted photometric and spectroscopic observations of a cataclysmic variable system designated SRGA J115215.0−510656. Results of the new observations, published April 29 on the arXiv pre-print server, indicate that the investigated system is an unusual long-period dwarf nova. Go to Source Four humans recently looped around the moon. Their vessel, an Artemis capsule, was a thin metal shell whose life-support system kept them alive: it provided a carefully balanced atmosphere, a closed water loop, a finite supply of food, and a means for disposing of human waste. The life support was not optional. It was a […] Astronomers using the NASA/ESA/CSA James Webb Space Telescope together with the NASA/ESA Hubble Space Telescope have looked deeply at thousands of young star clusters in four nearby galaxies, studying clusters at different stages of evolution. Their findings show that more massive star clusters emerge more quickly from the clouds they are born in, clearing away […] When solar storms strike Earth, they can disrupt power grids, rail systems, satellites, and even marine life. These effects arise because solar wind and geomagnetic activity disturb the magnetosphere–ionosphere system, generating electric and magnetic field variations that can resemble fainter signals from natural hazards. This risk is not theoretical. Go to Source […] Solar emissions exert ‘drag’ on space junk orbiting Earth. From historical measurements across a period of 36 years, researchers have now shown that space junk begins to fall down much faster once the sun’s activity across the solar cycle reaches approximately 67% of its peak. This result, which is expected to hold for station-keeping satellites […] The new focus on manned missions to the moon and Mars presents countless pressing challenges, including keeping humans alive in hostile environments. What happens when an astronaut or space tourist has a cardiac emergency millions of miles from the nearest hospital? Go to Source A half century after NASA’s Apollo 17 lunar module lifted off the moon’s northeastern near side quadrant, planetary scientists still don’t completely understand when or how our moon first formed. They do agree that it involved a major impactor—an object dubbed Theia by lunar scientists—that likely struck Earth some 4.51 billion years ago. But the […] NASA’s Juno spacecraft captured this view of Thebe, the second largest of Jupiter’s inner moons, during a close pass on May 1, 2026. The spacecraft’s Stellar Reference Unit (SRU) captured this image from a distance of approximately 3,100 miles (5,000 kilometers) at a resolution of about 1.9 miles (3 kilometers) per pixel.
