Laser scanning of Qin Shi Huang’s sealed tomb uncovers a mysterious signal, potentially confirming a 2,000‑year‑old imperial secret hidden beneath. Deep beneath a pyramid‑shaped mound near Lintong, roughly thirty kilometres northeast of Xi’an, an...

By splitting light into 102 distinct spectral bands, NASA’s SPHEREx telescope identified the clear signatures of water vapor, carbon dioxide, carbon monoxide, and methane. These findings are vital, as these molecules are also fundamental to the...

observations suggest these worlds might also host heavier, more complex gases such as carbon monoxide, carbon dioxide, or water vapor. While the exact chemical makeup of the gases surrounding HD 3167 b remains an open question, further investigations...

Europa a prime candidate in the extraterrestrial life search. Similarly, Saturn’s moon, Enceladus, has been found to emit water vapor plumes from its surface, suggesting another potential site for extraterrestrial organisms. The SETI Institute continues...

preprint archive, identified carbon dioxide as the primary driver of this activity. Notably, the telescope detected no water vapor, suggesting that the object is not undergoing standard water-ice sublimation. “At 450P’s distance from the sun, the...

1140 b’s atmosphere makes it a prime candidate for deeper spectroscopic studies aimed at uncovering other gases such as water vapor, carbon dioxide, or methane. Robin Wordsworth, Gordon McKay Professor of Environmental Science and Engineering at...

various gases. Researchers will look for potential biosignatures—combinations of molecules such as oxygen, methane, and water vapor that might indicate biological processes. While the detection of such gases would be intriguing, scientists caution that...

Scientists gear up for the August 12 total solar eclipse, a rare chance to capture data unattainable by spacecraft probing the Sun’s outer atmosphere. A total solar eclipse on 12 August will sweep across eastern Greenland, western Iceland and northern...

site near the water-ice line—the critical boundary roughly 4.5 billion years ago where temperatures became low enough for water vapor to transition into ice. Researchers believe that fine dust and icy components converged here, creating the raw...

Learn about Sudan Black B Stain—its purpose, principle, procedure, and interpretation. Discover how this essential stain aids in diagnosing leukemia and other hematological disorders. Sudan Black B (SBB) is a lipid-soluble dye used in hematology and...

need to see pale blue dots Directly imaging exoplanets is a stepping stone toward analyzing atmospheres, searching for water vapor, oxygen related chemistry, or other hints of life friendly. Roman’s coronagraph is a technology demonstration, but...

a biodiversity hotspot, the Amazon functions as a climate regulator. Its trees create “flying rivers”—airborne streams of water vapor that help irrigate vast regions, including the Cerrado savanna. The forest also plays a key role in forming clouds...

were previously trapped in deep layers of frozen material. These emissions produced a coma containing carbon dioxide, water vapor, carbon monoxide, and dust particles. The presence of such volatiles is characteristic of ancient cometary material that...

and driest places on Earth. Those conditions are actually good for millimeter astronomy because there is very little water vapor in the air. The telescope was built mainly to study the cosmic microwave background. Over time, its instruments have become...

Fossil dinosaur egg found with another egg inside, a bizarre first that could reshape our understanding of titanosaur reproduction. Among a clutch of eleven titanosaur eggs unearthed from the Lameta Formation in Dhar District, Madhya Pradesh, one...

years, famously sampled by NASA’s Cassini spacecraft. As these plumes burst through cracks in the icy crust, they eject water vapor and frozen droplets into space, where they populate Saturn’s E ring. While Cassini provided a revolutionary look at these...

Sealed for 2,200 years, Qin Shi Huang’s tomb allegedly hides deadly traps and mercury rivers. What do soil tests and ancient texts reveal about the site? Beneath a sprawling earthen mound in China’s Shaanxi Province, the tomb of Qin Shi Huang has...

Researchers have discovered a microscopic grain that survived the Hiroshima fireball, revealing a strange internal structure locked inside for decades. Tucked away within the mundane sand dunes along Hiroshima Bay lie microscopic remnants of a...

a product of temperature and pressure rather than a significant chemical difference. Although the team identified water vapor and carbon dioxide in the atmosphere, their abundances appeared consistent across the limb. The variations in the observed...
