Exoplanets in debris disks
Debris disks around main-sequence stars are tenuous belts of dust thought to be produced when asteroids or other planetesimals collide and fragment. They are common: more than about a quarter of all main-sequence stars have debris disks and, since th.....»»
Research into marine plastic pollution reveals bacterial enzymes actively degrading plastic
A new study led by researchers at the University of Stirling has uncovered the crucial roles of bacteria living on plastic debris. The research also identifies rare and understudied bacteria that could assist in plastic biodegradation, offering new i.....»»
Hiroshima fallout debris linked to first solar system condensates
The atomic bombing of Hiroshima, Japan, by the United States in August 1945 was not only devastating at the time, resulting in the deaths of hundreds of thousands of people, but it has had long-standing impacts to the present day, particularly the el.....»»
Japanese space debris inspection probe launched
A Japanese firm said Monday it had successfully launched a spacecraft tasked with inspecting potentially dangerous man-made junk floating around the Earth......»»
Newborn gas planets may be surprisingly flat, says new research
A new planet starts its life in a rotating circle of gas and dust, a cradle known as a protostellar disk. My colleagues and I have used computer simulations to show that newborn gas planets in these disks are likely to have surprisingly flattened sha.....»»
James Webb photographs two potential exoplanets orbiting white dwarfs
The James Webb Space Telescope recently imaged two potential exoplanets orbiting around small, cold cores of dead stars called white dwarfs......»»
JWST data suggest exoplanet K2-18b may have molten surface rather than a watery ocean
A multi-institutional team of astronomers, Earth scientists and planetary physicists has found evidence, via data from the James Webb Space Telescope (JWST), that some hycean exoplanets may have molten surfaces rather than watery oceans. In their stu.....»»
Mud and debris are flowing down hillsides across California. What causes the slides?
When rainstorms like this week's powerful atmospheric river hit California, the earth begins to move......»»
Newly discovered carbon monoxide-runaway gap can help identify habitable exoplanets
The search for habitable exoplanets involves looking for planets with similar conditions to the Earth, such as liquid water, a suitable temperature range and atmospheric conditions. One crucial factor is the planet's position in the habitable zone, t.....»»
Extreme eruption on young sun-like star signals savage environment for developing exoplanets
Astronomers have detected an extreme eruption from a young star that became more than a hundred times brighter in only a few hours. This discovery offers new insight into how young sun-like stars behave early in their lives, and their impact on the d.....»»
Neptune-like exoplanets can be cloudy or clear: New findings suggest the reason why
The study of "exoplanets," the sci-fi-sounding name for all planets in the cosmos beyond our own solar system, is a fairly new field. Mainly, exoplanet researchers like those in the ExoLab at the University of Kansas use data from space-borne telesco.....»»
Why interstellar objects like ‘Oumuamua and Borisov may hold clues to exoplanets
Two celestial interlopers in Solar System have scientists eagerly anticipating more. Enlarge / The first interstellar interloper detected passing through the Solar System, 1l/‘Oumuamua, came within 24 million miles of the Sun i.....»»
Japan government accepts it’s no longer the ’90s, stops requiring floppy disks
Government amends 34 ordinances to no longer require diskettes. Enlarge (credit: Getty) The Japanese government is finally letting go of floppy disks and CD-ROMs. It recently announced amendments to laws requiring the u.....»»
Researchers are spying for signs of life among exoplanet atmospheres
The next generation of advanced telescopes could sharpen the hunt for potential extraterrestrial life by closely scrutinizing the atmospheres of nearby exoplanets, new research suggests......»»
Astronomers analyze masses, orbital properties and atmospheric features of six exoplanets
A recently discovered solar system with six confirmed exoplanets and a possible seventh is boosting astronomers' knowledge of planet formation and evolution. Relying on a globe-spanning arsenal of observatories and instruments, a team led by research.....»»
The next generation LIFE telescope could detect some intriguing biosignatures
The Large Interferometer for Exoplanets (LIFE) project is an ambitious plan to build a space telescope with four independent mirrors. The array would allow the individual mirrors to move closer or farther apart, similar to the way the Very Large Arra.....»»
Research suggests European Alps eroding slower than >10,000 years ago
Deglaciation during the Holocene (last ~17,000 years) has had significant impacts on the surrounding mountainous environments as glaciers retreated and left distinct landforms in their wake, such as debris ridges (moraines) deposited at the snout dur.....»»
Simulations show that exoplanets heated at deeper depths by their host stars display markedly different weather patterns
For many years, most astrophysical models assumed that planets beyond our solar system, known as exoplanets, are heated at similar depths by their host stars (i.e., stars like the sun around which planetary systems are formed). Analyses of recent obs.....»»
TESS discovers nine new "hot Jupiters"
Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered nine new "hot Jupiter" exoplanets. One of the newly detected alien worlds is almost four times more massive than Jupiter. The finding was p.....»»
Chameleon AI program classifies objects in satellite images faster
A new AI program can train neural networks using just a handful of images to rapidly characterize in satellite and drone data new objects such as ocean debris, deforestation zones, urban areas and more......»»
This self-eating rocket could be a solution to space junk
Every year, space junk becomes a bigger problem. We saw the International Space Station dodging debris several times over the past few years, and we’ve … The post This self-eating rocket could be a solution to space junk appeared first on.....»»
