A total solar eclipse takes place on April 8 across North America. These events occur when the Moon passes between the Sun and Earth, completely blocking the Sun’s face. This plunges observers into a darkness similar to dawn or dusk. During the upcoming eclipse, the path of totality, where observers experience the darkest part of

Australia’s carbon credit scheme was undermined by damning new research Wednesday, which found a world-leading reforestation project had been an underperforming “catastrophe”. Vast swathes of land across Australia’s desert Outback have been earmarked for native forest regeneration, which is meant to offset emissions as new trees suck up carbon. But researchers have found that across

SAN FRANCISCO – Planet announced a $20 million agreement to provide hyperspectral data for Carbon Mapper’s greenhouse gas monitoring campaign. The deal, which extends from 2026 to 2030, “will help Carbon Mapper deliver high resolution methane and CO2 super-emitter data to decision makers around the globe,” Carbon Mapper CEO Riley Duren said in a statement.

It’s one of the biggest questions in science: to what extent are we defined by our genetics? A new analysis of Ludwig van Beethoven’s DNA, showing a low predisposition for beat synchronization, hints that we can become much more than our genes suggest. In other words, the celebrated German composer’s musical talents reached far beyond

A grain of dust recovered from an ancient meteorite that plonked itself down in Antarctica appears to be from a rather unusual place in space and time. It’s a tiny speck of a mineral called olivine, and its isotope composition is so alien that it could only have been produced by another star, dying before

Planting trees in the wrong places can actually contribute to global warming, scientists said on Tuesday, but a new map identifies the best locations to regrow forests and cool the planet. Trees soak up carbon dioxide and restoring areas of degraded woodlands or planting saplings to boost forest cover is one tool in the fight

ARLINGTON, Va. — Gen. Chance Saltzman, chief of space operations, said the U.S. Space Force has robust intelligence about what foreign adversaries are doing in outer space. Still, military leaders always want more comprehensive data and analysis about activities in orbit, he said March 27.  “I don’t often get surprised by things I hear,”  Saltzman

Why did humans take over the world while our closest relatives, the Neanderthals, became extinct? It’s possible we were just smarter, but there’s surprisingly little evidence that’s true. Neanderthals had big brains, language and sophisticated tools. They made art and jewellery. They were smart, suggesting a curious possibility. Maybe the crucial differences weren’t at the

Stars are born from huge clouds of mostly hydrogen gas floating in space. Astronomers like me study this gas because it helps us understand how stars and galaxies form and grow. Hydrogen gas gives off a faint glow that is invisible to human eyes but can be observed with a telescope tuned to detect radio

Details are still emerging about the disaster that happened in the early morning of March 26, 2024, when the Dali, a large cargo ship on its way out of the port of Baltimore, hit a major bridge and caused it to collapse. The Conversation’s senior politics and democracy editor, Naomi Schalit, spoke with Captain Allan

Operators of satellites in non-geostationary orbit (NGSO) could be forced to turn off beams when flying over countries that have not authorized them, do more to disable bootleg dishes in these territories, or a mix of both, depending on who you ask about new global rules in the works. Approval to study ways for cracking

The International Space Station won’t be around forever, and NASA is pouring hundreds of millions of dollars into its potential replacements. One promising candidate is Orbital Reef – a joint venture between Jeff Bezos’s space company Blue Origin and Sierra Space. On Wednesday, NASA reported that Orbital Reef passed four key milestones for some of

TAMPA, Fla. — The U.K.’s space agency plans to open new headquarters in June at the Harwell Science Campus space cluster in England to strengthen ties with the commercial industry. UK Space Agency (UKSA) has been headquartered in nearby Swindon since it was born out of the British National Space Centre 14 years ago. It

The voice of a woman largely overlooked by history has been discovered in a “dangerous” declaration attributed to the father of famous playwright William Shakespeare. It’s known as the “Spiritual Testament“, discovered in the rafters of Shakespeare House in Stratford-Upon-Avon in 1757, signed by one J. Shakespeare. Historians have interpreted this J. Shakespeare to mean

The Earth’s place in space is a fairly familiar one with it orbiting an average star. The star – our Sun – orbits the centre of our Galaxy the Milky Way. From here onwards, the story is less well known. The Milky Way is part of a large structure called the Laniakea Supercluster which is

The last time Patricia Cooper attended a meeting of the American Astronomical Society, she wasn’t sure what she was getting into. It was January 2020 and Cooper, at the time a vice president at SpaceX, had agreed to represent the company on a panel discussion at the conference on the interference satellite constellations could create

Contrary to what we may have assumed about the migration of modern humans out of Africa, at least some movement may have been driven, not by ‘green corridors‘, but by privation. A new analysis involving volcanic glass found in Ethiopia reveals humans lived in what could have been drought conditions in the Horn of Africa

There are plenty of craters on Mars, especially when compared to Earth. That is primarily thanks to the lack of weathering forces and strong plate tectonics that disrupt the formations of such impacts on our home planet. However, not all impact craters on Mars are directly caused by asteroid impacts. Many of them are caused

WASHINGTON — AT&T is prepared to provide more funds to help get AST SpaceMobile’s direct-to-smartphone constellation plans off the ground. AST SpaceMobile raised $155 million from AT&T and other investors in January, but the satellite operator needs more capital to provide 5G connectivity globally from low Earth orbit to phones and other devices outside cell

There’s a large part of human history hidden beneath the sea. From Canada’s coastlines to the flat underwater fringes of Australia, sunken sites around the world have delivered troves of artifacts that give archaeologists a deeper understanding of where ancient humans lived and how they potentially traversed treacherous seas to reach new lands. Stone Age

Relics of the Milky Way’s birth have just been discovered hiding in plain sight. Towards the center of the galaxy, two streams of stars nearly as old as the Universe have been discovered circling the heart of the Milky Way. A new analysis based on data from the European Space Agency’s Gaia telescope strongly suggests

Our love for coffee means millions of tons of spent coffee grounds going to waste every single year. Scientists have been working on ways to make use of them, and we now have another to add to the list: old coffee grounds have been shown to absorb bentazone, a herbicide used in agriculture. If the

Neuralink on Wednesday streamed a video of its first human patient playing computer chess with his mind and talking about the brain implant making that possible. Noland Arbaugh, 29, who was left paralyzed from the shoulders down by a diving accident eight years ago, told of playing chess and the videogame “Civilization” as well as

WASHINGTON — Soaring demand for backup connectivity after subsea cables were cut in the Red Sea is helping push Rivada Space Networks closer to fully financing its $2.4 billion constellation plans, according to CEO Declan Ganley. In the weeks following an incident affecting a quarter of the internet traffic passing between Asia, Europe, and the Middle East,

For Michel Talagrand, who won the Abel mathematics prize on Wednesday, maths provided a fun life free from all constraints – and an escape from the eye problems he suffered as a child. “Maths, the more you do it, the easier it gets,” the 72-year-old said in an interview with AFP. He is the fifth

There’s something peculiar about dying star Betelgeuse. Yeah, there was the whole sneeze thing. That’s been pretty much resolved for now. But before the Great Dimming Debacle of 2019, scientists spotted something even more peculiar about the giant star. Radio measurements of its changing light suggested it was rotating at 5 kilometers (3.1 miles) per

Global temperatures “smashed” heat records last year, as heatwaves stalked oceans and glaciers suffered record ice loss, the United Nations said Tuesday – warning 2024 was likely to be even hotter. The annual State of the Climate report by the UN weather and climate agency confirmed preliminary data showing 2023 was by far the hottest

A company co-founded by Bill Gates is about to start building next-generation nuclear power plants in the US. Chris Levesque, CEO of TerraPower, told the Financial Times that his firm will start building at a site near a coal plant in Kemmerer, Wyoming in June, even if it hasn’t received a construction permit from regulators

WASHINGTON — Geostationary satellite operator Intelsat has bought at least five times more capacity from Eutelsat’s OneWeb low Earth orbit (LEO) constellation to strengthen its multi-orbit broadband strategy. The companies announced March 19 that Intelsat has made a firm commitment to buy $250 million worth of LEO capacity over six years starting mid-2024. Intelsat also
