By Will Dunham WASHINGTON (Reuters) – In 1995, astronomers confirmed the discovery for the first time of a brown dwarf, a body too small to be a star and too big to be a planet – sort of a celestial tweener. But it turns out that was not the full story. Researchers now have taken a fresh look at that brown dwarf and learned that it actually is not a single brown dwarf but rather […]

SpaceX catches giant Starship booster in fifth flight test
By Joey Roulette (Reuters) -SpaceX in its fifth Starship test flight on Sunday returned the rocket’s towering first stage booster back to its Texas launch pad for the first time using giant mechanical arms, achieving another novel engineering feat in the company’s push to build a reusable moon and Mars vehicle. The rocket’s first stage “Super Heavy” booster lifted off at 7:25 a.m. CT (1225 GMT) from SpaceX’s Boca Chica, Texas launch facilities, sending the […]
Webb telescope reveals surprising details of Pluto’s moon Charon
By Will Dunham WASHINGTON (Reuters) – Observations by the James Webb Space Telescope are giving scientists a fuller understanding about the composition and evolution of Pluto’s moon Charon, the largest moon orbiting any of our solar system’s dwarf planets. Webb for the first time detected carbon dioxide and hydrogen peroxide – both frozen as solids – on the surface of Charon, a spherical body about 750 miles (1,200 km) in diameter, researchers said on Tuesday.

‘Danger behind the beauty’: more solar storms could be heading our way
By Daniel Lawler PARIS, May 18, 2024 (AFP) – Tourists normally have to pay big money and brave cold climates for a chance to see an aurora, but last weekend many people around the world simply had to look up to see these colourful displays dance across the sky. Usually banished to the poles of Earth, the auroras strayed as far as Mexico, southern Europe and South Africa on the evening of May 10, delighting […]
Third time could prove lucky for aurora viewers around the world
By Issam AHMED with AFP bureaus around the world WASHINGTON, May 13, 2024 (AFP) – Anyone who missed the dazzling auroras dancing across night skies earlier this weekend will get another chance Sunday evening, as the powerful geomagnetic storm hitting the Earth is expected to intensify yet again. “Several intense Coronal Mass Ejections are still anticipated to reach the Earth’s outer atmosphere by later today,” the US National Weather Service said. Those ejections — expulsions […]
Second night of auroras seen ‘extreme’ solar storm
By Lucie AUBOURG with AFP bureaus around the world WASHINGTON, May 12, 2024 (AFP) – Auroras lit up skies across swaths of the planet for the second night in a row on Saturday, after already dazzling Earthlings from the United States to Tasmania to the Bahamas the day before. A powerful solar storm — which could continue into Sunday — has triggered spectacular celestial shows usually confined to the far northern reaches of the […]
First ‘extreme’ solar storm in 20 years brings spectacular auroras
By Issam AHMED WASHINGTON, May 11, 2024 (AFP) – The most powerful solar storm in more than two decades struck Earth on Friday, triggering spectacular celestial light shows in skies from Tasmania to Britain — and threatening possible disruptions to satellites and power grids as it persists into the weekend. The first of several coronal mass ejections (CMEs) — expulsions of plasma and magnetic fields from the Sun — came just after 1600 GMT, according […]
Climate change changing Earth’s time: study
By Daniel Lawler and Juliette Collen PARIS, March 27, 2024 (AFP) – Struggle to wrap your head around daylight savings? Spare a thought for the world’s timekeepers, who are trying to work out how climate change is affecting Earth’s rotation — and in turn, how we keep track of time. In a strange twist, global warming could even help out timekeepers by delaying the need for history’s first “negative leap second” by three years, a […]
‘Very worried’: Scientists fret as Antarctic sea ice dwindles
By Juan BARRETO, Juan RESTREPO ON BOARD THE ARC SIMON BOLIVAR, Antártida, March 2, 2024 (AFP) – Sea ice levels in Antarctica have registered historic lows for three consecutive years, portending grave consequences for life on Earth as we know it. But looking out over the southernmost continent, scientist Miguel Angel de Pablo laments that humanity seems to be oblivious to the warnings. “We (scientists) are very worried… because we don’t see how we can […]
Modi says India’s first astronauts will inspire nation
NEW DELHI, Feb 27, 2024 (AFP) – Indian Prime Minister Narendra Modi on Tuesday toasted the four astronauts preparing for the nation’s first crewed orbital mission, saying the latest advance in spacefaring would inspire the next generation. “The countdown of the rocket inspires thousands of children in India, and those making paper planes today dream of becoming scientists like you”, Modi said. The Gaganyaan — or “Skycraft” — mission is slated to launch the astronauts […]
World’s biggest flying lab takes off in Asia, fighting air pollution for millions
CLARK, Philippines, Feb 9, 2024 (AFP) – NASA has kicked off a series of marathon flights in Asia with the world’s biggest flying laboratory, in an ambitious mission to improve the models that help to forecast and fight air pollution. Millions of deaths each year are linked to air pollution, and improving the ability to identify its sources and behaviour can lead to more accurate warning systems for the public. Starting this week in the […]
Six exoplanets discovered in synchronised dance around star
By Juliette Collen PARIS (AFP) – Six exoplanets have been spotted in a perfectly synchronised dance around a nearby star, offering clues about the formation of our own Solar System, astronomers said on Wednesday. The six planets orbit the bright star HD 110067 around 100 light years away from Earth. The star is visible from the Northern Hemisphere as part of the Coma Berenices constellation. The planets are so close to their star that all […]
