Astronomers puzzled by "planet that shouldn"t exist"
The search for planets outside our solar system—exoplanets—is one of the most rapidly growing fields in astronomy. Over the past few decades, more than 5,000 exoplanets have been detected and astronomers now estimate that on average there is at l.....»»
Geologists rewrite textbooks with new insights from Cambrian rocks of Grand Canyon
Since soon after our planet formed, Earth's 4.6 billion-year-long history was dominated by single-celled life. Something dramatic happened about 500 million years ago called the Cambrian "explosion," during which an incredible diversity of life forms.....»»
Advances in plate tectonics research provide a new view of deep Earth"s carbon emissions
From time to time, when Earth's tectonic plates shift, the planet emits a long, slow belch of carbon dioxide. In a new modeling study published in Geochemistry, Geophysics, Geosystems, R. Dietmar Müller and colleagues show how this gas released from.....»»
Nearly three years since launch, Webb is a hit among astronomers
Demand for observing time on Webb outpaces supply by a factor of nine. From its halo-like orbit nearly a million miles from Earth, the James Webb Space Telescope is seeing farther.....»»
Experiment reveals how Earth"s magnetic field influences flow in planet"s core
A trio of physicists, two with Coventry University, in the U.K., and the third with Laboratoire National des Champs Magnétiques Intenses, in France, has demonstrated how Earth's magnetic field may be influencing internal flow, using what they descri.....»»
Mighty radio bursts linked to massive galaxies: New clues about how magnetars form
Since their discovery in 2007, fast radio bursts—extremely energetic pulses of radio-frequency light—have lit up the sky repeatedly, leading astronomers on a chase to uncover their origins. Currently, confirmed fast radio bursts, or FRBs, number.....»»
Astronomers use JWST and ALMA to explore the structure of a giant spiral galaxy
Using the James Webb Space Telescope (JWST) and the Atacama Large Millimeter/submillimeter Array (ALMA), an international team of astronomers have observed a giant spiral galaxy designated ADF22.A1. Results of the observational campaign, published Oc.....»»
Microbial slime: The ultimate system to understand our planet
Billions of years ago, Earth was home to extreme environments, including intense UV radiation, frequent volcanic eruptions, and very high concentrations of carbon dioxide in the atmosphere. Yet, under these conditions, biofilms formed and within thes.....»»
The frozen carbon of the northern permafrost is on the move—we estimated by how much
Among the most rapidly changing parts of our planet are the coldest landscapes near the top of the globe, just south of the Arctic. This region is warming two to four times faster than the global average......»»
Earth underwent a massive, rapid melting period after the last global ice age, new study suggests
At the end of the last global ice age, the deep-frozen Earth reached a built-in limit of climate change and thawed into a slushy planet. Results from a Virginia Tech-led study provide the first direct geochemical evidence of the slushy planet—other.....»»
African countries shouldn"t have to borrow money to fix climate damage they never caused, says economist
As we approach the global annual climate change conference, COP29, the need for increased public finance from the global north to address climate adaptation in Africa has become more urgent than ever......»»
Globular cluster Gran 5 hosts two stellar populations, study finds
Using the Gemini-South telescope, astronomers have performed high-resolution near-infrared spectroscopy of stars in a Galactic globular cluster known as Gran 5. They found that this cluster harbors two stellar populations with different metallicities.....»»
Bio-based fibers could pose greater threat to environment than conventional plastics
Bio-based materials may pose a greater health risk to some of the planet's most important species than the conventional plastics they are designed to replace, a new study has shown......»»
Webb confirms a longstanding galaxy model
Perhaps the greatest tool astronomers have is the ability to look backward in time. Since starlight takes time to reach us, astronomers can observe the history of the cosmos by capturing the light of distant galaxies......»»
Sick of supersized EVs? The 2025 Hyundai Kona Electric hits the spot.
It's not too big, it's not too heavy, and it's very, very efficient. If conventional wisdom were to be believed, the car we're reviewing today should not exist. Automakers are on.....»»
COP29: AI can help develop climate-resistant crops for Africa—but it shouldn"t be left in the hands of corporates
How we use land and feed a growing global population, and the burden we place on natural habitats in pursuit of nutrition, will again take center stage at the annual global climate change conference, COP29, in November......»»

Observations detect hundreds of possible supergiant stars in two nearby galaxies
Using the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST), Chinese astronomers have identified nearly 300 candidate supergiant stars in the Andromeda and Triangulum galaxies. The finding was reported in a research paper published O.....»»
