color data with Webb’s infrared sensitivity, the team was able to categorize these bodies into two distinct groups: “cold” TNOs, which reside in stable, near-circular orbits, and “hot” TNOs, which were likely displaced during the gravitational migration...

melting points. Final state of three identical Moon-forming simulations with different initial temperature profiles, from cold to hot: Tsurf ≈ 400 K (top row), Tsurf ≈ 800 K (middle row), and Tsurf ≈ 2000 K (bottom row), with strength included, shown at...

New fossil evidence reveals that some of the largest dinosaurs thrived in surprisingly cold climates, defying long-held beliefs about their nesting habits. New evidence uncovered in the rugged landscapes of southern Argentina suggests that titanosaurs,...

a complex assembly of six distinct components. At its heart lies C2c1a(a), a primary structure anchored within a massive, cold reservoir containing at least 110 solar masses of gas and dust. Despite this high-resolution clarity, the team faced a...

JWST has discovered that the giant exoplanet HATS-6 b is colder and chemically unique, challenging our current understanding of how planets form. The James Webb Space Telescope (JWST) has turned its gaze toward HATS-6 b, a peculiar giant exoplanet that...

Subsequent loss of atmosphere and water—driven by low gravity and the lack of a global magnetic shield—led to the cold, dry world observed today. Oxford geophysicist Jon Wade suggests the findings broaden the criteria for planetary habitability. “If...

from the deep sea east of New Zealand’s South Island, with deeper basins to its north and south. This topography forces cold, nutrient‑rich Antarctic waters upward as they encounter the plateau, where they mix with warmer, nutrient‑poor subtropical...

Tardigrades, the microscopic ’water bears’, survived space vacuum, extreme cold and intense radiation in lab tests, proving near‑indestructibility. The debate over how life first appeared on Earth has long inspired theories that the cosmos could have...

prompting novel verification methods for a vehicle that has never flown before. Ensuring Survival in Titan’s Extreme Cold Beyond structural soundness, engineers performed meticulous sealing examinations to confirm that the lander can protect its...

simple two‑carbon alcohols and aldehydes. These ice‑coated dust grains act as natural reactors where radiation and extreme cold drive chemistry that would be difficult to reproduce in terrestrial laboratories. “This finding was unexpected, as the...

and the distribution of interstellar dust throughout the Milky Way. Among the cataloged objects are the host stars of two cold exoplanets of particular interest, notably OGLE‑2013‑BLG‑341Lb—a binary star with a single planet. By merging earlier Keck and...

Climate Evolution This discovery adds a new piece to the puzzle of Mars’ transition from a once‑active environment to the cold, arid world observed today. The Mirador formation, rich in ancient wind‑related signatures, continues to illuminate...

sequences were compared against existing viral databases, many displayed adaptations that would facilitate survival in cold, nutrient‑limited settings, suggesting that these viruses were well‑suited to the harsh glacial environment. “These are viruses...

a Chain of Failures The B‑52G, call‑sign “Tea 16,” had departed Seymour Johnson Air Force Base the day before as part of the Cold‑War “Operation Chrome Dome,” which kept nuclear‑armed bombers aloft to guarantee a retaliatory strike. After completing two...

mechanism offers a compelling explanation for how Mars transitioned from a once‑wet world with a thick atmosphere to the cold, arid planet observed today. Solar Wind Generates Colossal Plasma Ripples at the Top of Mars’ Atmosphere Because Mars lacks a...

carrying thermal energy beyond the nebula’s confines. Second, turbulent mixing at the shell boundaries can blend hot and cold material, lowering overall temperatures and reducing X‑ray brightness. Third, thermal conduction—analogous to heat transfer...

this feature was eventually identified as a wake of newly formed stars ignited by the black hole’s passage through cold gas. The object is located roughly 7.5 billion light-years from Earth. Scientists first dismissed the line as an imaging artifact...

their findings, the team utilized the Atacama Large Millimeter/submillimeter Array (ALMA). This allowed them to observe the colder gas and dust environments that surround the hot, young stars. The absence of specific emission lines—namely broad...

from our own solar system,” said Dr. Ferellec. “Finding that it’s so rich in nitrogen tells us it likely formed in extremely cold conditions, far from its home star. Every one of these objects we study helps us understand a little more about how planets...
