Astronomers estimate Titan"s largest sea is 1,000-feet deep
Far below the gaseous atmospheric shroud on Saturn's largest moon, Titan, lies Kraken Mare, a sea of liquid methane. Cornell University astronomers have estimated that sea to be at least 1,000-feet deep near its center—enough room for a potential r.....»»
Tidal disruption event ASASSN-19bt experiences unusual radio evolution, observations show
An international team of astronomers has conducted detailed radio and X-ray observations of a tidal disruption event (TDE) designated ASASSN-19bt. Results of the observational campaign, presented April 18 on the pre-print server arXiv, shed more ligh.....»»
Orion"s erupting star system reveals its secrets
An unusual group of stars in the Orion constellation have revealed their secrets. FU Orionis, a double star system, first caught astronomers' attention in 1936 when the central star suddenly became 1,000 times brighter than usual. This behavior, expe.....»»
Details of hurricane Ian"s aftermath captured with new remote sensing method
Category 4 Hurricane Ian made landfall in Florida's Lee County on Sept. 28 2022, battering the region with wind speeds of 155 miles per hour and storm surge up to 13 feet—the highest storm surge documented in Southwest Florida in the past 150 years.....»»
The Mysterious ‘Dark’ Energy That Permeates the Universe Is Slowly Eroding
Physicists call the dark energy that drives the universe “the cosmological constant.” Now the largest map of the cosmos to date hints that this mysterious energy has been changing over billions of years......»»
Human activities have an intense impact on Earth"s deep subsurface fluid flow
The impact of human activities—such as greenhouse gas emissions and deforestation—on Earth's surface have been well-studied. Now, hydrology researchers from the University of Arizona have investigated how humans impact Earth's deep subsurface, a.....»»
Mapping the Milky Way"s magnetic field in 3D
We are all very familiar with the concept of the Earth's magnetic field. It turns out that most objects in space have magnetic fields but it's quite tricky to measure them. Astronomers have developed an ingenious way to measure the magnetic field of.....»»
The first glow-in-the-dark animals may have been ancient corals deep in the ocean
Many animals can glow in the dark. Fireflies famously blink on summer evenings. But most animals that light up are found in the depths of the ocean......»»
US’s power grid continues to lower emissions—everything else, not so much
Excluding one pandemic year, emissions are lower than they've been since the 1980s. Enlarge (credit: US EIA) On Thursday, the US Department of Energy released its preliminary estimate for the nation's carbon emissions in.....»»
Here’s how that iPhone survived a 16,000-foot drop from the Alaska Airlines plane
Back in January, a fully intact iPhone was discovered along the side of the road after plummeting 16,000 feet when a door blew off an Alaska Airlines flight. At the time, we pointed out that it was pretty incredible the iPhone 14 Pro Max survived suc.....»»
Research investigates radio emission of the rotating radio transient RRAT J1854+0306
Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST), Chinese astronomers have investigated radio emission from a rotating radio transient known as RRAT J1854+0306. Results of the study, published April 15 on the preprint server arX.....»»
NASA"s Deep Space Optical Communications demonstration transmits data over 140 million miles
Riding aboard NASA's Psyche spacecraft, the agency's Deep Space Optical Communications technology demonstration continues to break records. While the asteroid-bound spacecraft doesn't rely on optical communications to send data, the new technology ha.....»»
TESS finds its first rogue planet
Well over 5,000 planets have been found orbiting other star systems. One of the satellites hunting for them is TESS, the Transiting Exoplanet Survey Satellite. Astronomers using TESS think they are made a rather surprising discovery; their first free.....»»
Scientists combine a spatially distributed sediment delivery model and biogeochemical model to estimate fluxes by water
Water erosion is the most active process controlling soil formation and evolution, which can affect the redistribution of carbon between terrestrial, aquatic, and atmospheric ecosystems. Erosion-induced organic carbon dynamic process should not be mi.....»»
Cocaine is an emerging contaminant of concern in the Bay of Santos (Brazil), says researcher
In addition to already known pollutants, the Bay of Santos—a city in the state of São Paulo (Brazil) that is home to the largest seaport in Latin America—has been affected by an emerging contaminant that is now present not only in the water but.....»»
New GM North America chief Marissa West has deep ties to automaker
While growing up, General Motors' first female North American president would collect brochures at the Detroit auto show and pretend to run her own dealership......»»
Recently discovered black hole is part of a nearby disrupted star cluster, study finds
European astronomers have investigated a recently detected black hole designated Gaia BH3. In their results, they found that the black hole is associated with a nearby disrupted star cluster known as ED-2. The finding is reported in a paper published.....»»
The guardian angels of the source of the Seine
