Researchers explore novel approach to map forest dieback in satellite images
Forests and woodlands cover one third of Earth's surface and play a critical role in carbon sequestration, water regulation, timber production, soil protection, and biodiversity conservation. Accelerated by climate change, the decline of these and ot.....»»
Atmospheric methane increase during pandemic due primarily to wetland flooding, satellite data analysis finds
A new analysis of satellite data finds that the record surge in atmospheric methane emissions from 2020 to 2022 was driven by increased inundation and water storage in wetlands, combined with a slight decrease in atmospheric hydroxide (OH). The resul.....»»
Astronomers catch a glimpse of a uniquely inflated and asymmetric exoplanet
An international group of researchers including University of Arizona astronomers, using NASA's James Webb Space Telescope, has observed the atmosphere of a hot and uniquely inflated exoplanet. The exoplanet, which is the size of Jupiter but only a t.....»»
Satellite images suggest test of Russian “super weapon” failed spectacularly

High-resolution images of the sun show how flares impact the solar atmosphere
Solar flares are a fascinating thing and have a profound effect on what astronomers refer to as "space weather." These events vary with the sun's 11-year solar cycle, releasing immense amounts of radiation across the electromagnetic spectrum (from ex.....»»
New millisecond pulsar discovered
Using the Green Bank Telescope (GBT), astronomers have observed a globular cluster known as Terzan 6. They detected a new millisecond pulsar that is likely associated with this cluster. The finding was reported in a research paper published September.....»»

Are you worried your Samsung Galaxy S24 Plus needs more than case protection? It's time for a screen protector. Here are our favorite ones so far......»»
Starlink imposes $100 “congestion charge” on new users in parts of US
One-time $100 fee in congested areas, and $100 credit in excess-capacity areas. Enlarge / Starlink satellite dish. (credit: Starlink) New Starlink customers have to pay a $100 "congestion charge" in areas where the satel.....»»
X-Ray Imaging and Spectroscopy Mission unveils black hole and supernova remnant surroundings
The X-Ray Imaging and Spectroscopy Mission (XRISM) has revealed the structure, motion and temperature of the material around a supermassive black hole and in a supernova remnant in unprecedented detail. Astronomers presented the first scientific resu.....»»
Arctic weather satellite"s first images capture Storm Boris
Just a month after its launch, ESA's Arctic Weather Satellite has already delivered its first images, notably capturing Storm Boris, which has been wreaking havoc across central Europe......»»
NASA"s Chandra finds galaxy cluster that crosses the streams
Astronomers using NASA's Chandra X-ray Observatory have found a galaxy cluster has two streams of superheated gas crossing one another. This result shows that crossing the streams may lead to the creation of new structure......»»
Astronomers just detected the biggest black hole jets ever seen—and named them Porphyrion
The largest known black hole jets, 23 million light years across, have been discovered in the distant universe. This pair of particle beams launched by a supermassive black hole is over a hundred times larger than our galaxy, the Milky Way......»»
Observers detect intraday variability of blazar 1ES 1426+42.8
Astronomers report the detection of optical intraday variability of a blazar known as 1ES 1426+42.8. The new findings, presented in a paper published in the September issue of Monthly Notices of the Royal Astronomical Society, could shed more light o.....»»

Observations provide crucial insights into the nature of a white dwarf–brown dwarf binary
Using the Hubble Space Telescope (HST), astronomers have performed spectrophotometric observations of an eclipsing white dwarf–brown dwarf binary known as WD1032+011. Results of their observational campaign, published September 10 on the preprint s.....»»
Chinese scientists claim they can use Starlink satellites to detect stealth aircraft
Chinese scientists claim that radiation from Starlink constellations will actually let them detect stealth aircraft. It’s a bold claim, but based on the evidence presented … The post Chinese scientists claim they can use Starlink satellites t.....»»
Geoscientists confirm "dripping" of Earth"s crust beneath Türkiye"s Central Anatolian Plateau
Recent satellite data reveal that the Konya Basin in the Central Anatolian Plateau of Türkiye is continually being reshaped over millions of years, according to a new analysis led by Earth scientists at the University of Toronto......»»
Second-gen Starlink satellites leak 30 times more radio interference, threatening astronomical observations
Observations with the LOFAR (Low Frequency Array) radio telescope last year showed that first generation Starlink satellites emit unintended radio waves that can hinder astronomical observations......»»
Reinventing the clock: NASA"s new tech for space timekeeping
Here on Earth, it might not matter if your wristwatch runs a few seconds slow. But crucial spacecraft functions need accuracy down to one billionth of a second or less. Navigating with GPS, for example, relies on precise timing signals from satellite.....»»
