Jerusalem’s ancient water system was not only about finding a spring. It was about controlling what happened when the water came too quickly and when the rain failed to arrive at all. A new study has dated a large dam near the Siloam Pool to roughly 805–795 BCE, during the period when the kingdom of […]

The desert north of Arabia has kept a Roman military story out of sight for almost two thousand years. Now three angular traces in the landscape are giving archaeologists a possible route to follow. Researchers working with satellite imagery have identified three Roman marching camps in the Harrat al-Shaam region, close to the ancient frontier […]

Astronomers have found a third giant planet around Beta Pictoris, one of the best-known young planetary systems near Earth. The discovery is striking because the planet was not first picked out as a bright dot in a telescope image. NASA’s James Webb Space Telescope found it in the spectrum of light coming from the system: […]

NASA is currently targeting August 30 for the launch of the Nancy Grace Roman Space Telescope from Florida. The date can move, as launch dates do, but the mission is close enough to the pad that its central idea deserves a clear look: Roman will survey huge stretches of the universe in one exposure, gathering […]

A laser survey of southwestern Amazonia has changed the scale of an old archaeological question. The aircraft did not reveal a hidden stone city, and it did not count 20,000 monuments one by one. What it did reveal was a dense pattern of ancient earthworks beneath the forest canopy—enough for the research team to estimate […]

NASA says a new four-spacecraft mission has completed an early test that could make one of the hardest parts of space-weather forecasting much more precise: estimating when a solar eruption will reach Earth. In a proof-of-concept exercise announced on August 4, NASA’s PUNCH mission used continuous images of a coronal mass ejection, or CME, to […]

For nearly three decades, 1998 SH2 looked like a fairly ordinary near-Earth asteroid. It was discovered in 1998, catalogued, and followed through a 4½-year orbit around the Sun. Then, during a close but safe pass by Earth in August 2025, its motion refused to match the path astronomers had calculated. The explanation, announced by NASA […]

A star being torn apart by a black hole is already an unusual sight. In this case, the black hole was in an even stranger place: more than 30,000 light-years from the center of the galaxy that appears to host it. NASA’s Neil Gehrels Swift Observatory helped confirm the event after an automated survey spotted […]

Messier 87 is already famous for a photograph most people have seen: the Event Horizon Telescope image of the black hole at its center. Yet the black hole’s most dramatic feature is not the dark ring at the core. It is a jet of particles that extends thousands of light-years into space. Now, a team […]

A team of Mexican and Slovenian archaeologists has reported the discovery of a Maya city in the northern reaches of Mexico’s Calakmul Biosphere Reserve, a dense forested landscape already known for its extraordinary concentration of ancient settlements. The site has been named Minanbé, an expression in Yucatec Maya that the researchers translate as “there is […]

Pages of released UAP files do not settle the question of what is in the sky. They do show what government agencies were told, what their files retained and where the evidence breaks off. That is the value of the fifth tranche of records released on 7 August through the U.S. government’s UAP portal. Three […]

On Wednesday, August 12, the Moon’s shadow will sweep across a narrow stretch of the Northern Hemisphere. Greenland, Iceland, northern Russia, the Atlantic, Spain and a small corner of Portugal lie in the path of totality. Much of Europe, northwestern Africa, Canada and parts of the United States will see a partial eclipse. It is […]
