Clouds form each morning on WASP-94A b

Scientists using the James Webb Space Telescope found a daily cloud cycle on the Hot Jupiter WASP-94A b: sand-like clouds appear each morning and clear by evening. The finding helps measure the planet’s atmosphere more accurately.

JWST map reveals the cosmic web across time

A new map from NASA’s James Webb Space Telescope (JWST) traces the cosmic web across 13.7 billion years, reaching back to when the universe was one billion years old. The COSMOS-Web survey released maps, data and public tools.

Lasers steer tiny metajets in three dimensions

Researchers at Texas A&M used lasers to precisely steer microscopic metajets that move when lit. The study shows how patterned metasurfaces transfer momentum and suggests the idea could aid future light-powered space travel.

When a Star Is Torn Apart by a Black Hole

A new study explains how a star that wanders too close to a supermassive black hole is stretched into a thin debris stream. Collisions and later accretion make bright flares called tidal disruption events (TDEs), which simulations now model in detail.

Mechanical swarm that works without electronics

Georgia Tech researchers built tiny particles that latch, release and reorganize using only their physical shape. An external vibration makes the units open and spread; possible uses include medicine and space systems.

Bacteria survive asteroid-like impacts

A laboratory study shows a desert bacterium can survive extreme forces like those from asteroid impacts and then face space conditions. The results suggest rocks could move life between planets and raise planetary protection questions.

New analysis: Titan may have a slushy interior, not a deep ocean

Reanalysis of Cassini data suggests Titan has a thick, slushy layer with tunnels and pockets of meltwater near a rocky core rather than a single deep ocean. The result could change ideas about habitability and will be testable by the Dragonfly mission.

Study: Many small galaxies may lack central black holes

A University of Michigan-led study using Chandra X-ray data finds many dwarf galaxies do not show signs of central supermassive black holes. The result suggests the biggest black holes may have formed large early and could be tested by future missions.

New images reveal complex nova eruptions

Astronomers used interferometry at the CHARA Array to take direct images of two novae soon after they erupted. The pictures show multiple outflows and, in one case, a delayed release of material.

Study: Many mini‑Neptunes may have solid surfaces

A University of Chicago study using JWST data and computer models finds many mini‑Neptunes might have solid surfaces instead of global magma oceans, because heavy atmospheres can create extreme pressure at the surface.

Searching for Life on Exoplanets

Since a 1995 discovery, astronomers have found over 4,000 exoplanets. Scientists study biosignatures and technosignatures to learn if life or technology exists elsewhere. A NASA grant supports Adam Frank's work on technosignatures.

India launches sun probe after historic moon landing

India landed on the moon's south pole and, days later, launched a solar probe. The missions have renewed public pride, highlighted ISRO’s low-cost approach and prompted debate about science funding and priorities.
