Object found in the Milky Way ‘unlike anything astronomers have seen’

by Maddison Connaughton Agence France-Presse SYDNEY, Australia (AFP) – Australian researchers have discovered a strange spinning object in the Milky Way they say is unlike anything astronomers have ever seen. The object, first spotted by a university student working on his undergraduate thesis, releases a huge burst of radio energy three times every hour. The pulse comes “every 18.18 minutes, like clockwork,” said astrophysicist Natasha Hurley-Walker, who led the investigation after the student’s discovery, using […]

Head in the sky: 8-year-old Brazilian girl dubbed world’s youngest astronomer

by Jarbas OLIVEIRA, avec Louis GENOT, à Rio de Janeiro FORTALEZA, Brazil (AFP) — When Nicole Oliveira was just learning to walk, she would throw up her arms to reach for the stars in the sky. Today, at just eight years of age, the Brazilian girl is known as the world’s youngest astronomer, looking for asteroids as part of a NASA-affiliated program, attending international seminars and meeting with her country’s top space and science figures.

Partial eclipse sweeps over northern hemisphere

PARIS, France (AFP) — People across Earth’s northern hemisphere viewed an annular solar eclipse Thursday with parts of Canada and Siberia privy to the best view of the celestial event. The eclipse was partly visible to observers in North America, parts of Europe including France and the UK, and some of northern Asia. In London, where the moon covered 20 percent of the sun as the eclipse reached totality, sky-gazers glimpsed the event through cloud […]

Pacific readies for ‘Super Blood Moon’ celestial show

by Andrew BEATTY SYDNEY, Australia (AFP) — Stargazers across the Pacific Rim can cast their eyes skyward on Wednesday night and behold a “Super Blood Moon”, as the heavens align to bring a rare celestial twin treat. The first total lunar eclipse in two years is happening at the same time as the moon is closest to Earth, in what astronomers say will be a once-in-a-decade show. If the skies are clear, anyone living between […]

NASA’s giant Webb telescope succeeds in key pre-launch test

WASHINGTON, United States (AFP) — The world’s largest and most powerful space telescope unfolded its giant golden mirror for the last time on Earth on Tuesday, a key milestone before the $10 billion observatory is launched later this year. The James Webb Space Telescope’s 21 feet 4 inch (6.5 meter) mirror was commanded to fully expand and lock itself into place, NASA said — a final test to ensure it will survive its million-mile (1.6 […]

A ‘starter kit’ for supermassive black holes?

by Marlowe HOOD PARIS, France (AFP) — Scientists have reported the discovery of a rare, medium-sized black hole that may help answer one of the more tantalising questions in astronomy: how do their supermassive counterparts come into being? There are two well-known sizes of black hole — at one end, so-called stellar-class ones which are typically three to ten times the mass of our Sun — and at the other, supermassive ones, found at the […]

Jupiter and Saturn cheek-to-cheek in rare celestial dance

by Juliette COLLEN PARIS, France (AFP) — The solar system’s two biggest planets, Jupiter and Saturn, came within planetary kissing range in Monday’s evening sky, an intimacy that will not occur again until 2080. This “great conjunction”, as it is known to astronomers, occurred fortuitously on the winter solstice for those in the Northern Hemisphere and the beginning of summer in the global south. The two planets were, in fact, more than 730 million kilometers […]

China to open giant telescope to international scientists

by Ludovic EHRET PINGTANG, China (AFP) — Nestled among the mountains in southwest China, the world’s largest radio telescope signals Beijing’s ambitions as a global centre for scientific research. The Five-hundred-metre Aperture Spherical Telescope (FAST) — the only significant instrument of its kind after the collapse of another telescope in Puerto Rico this month — is about to open its doors for foreign astronomers to use, hoping to attract the world’s top scientific talent. The […]

Scientists detect mysterious ‘intermediate mass’ black hole

by Marlowe HOOD PARIS, France (AFP) — Scientists announced Wednesday the discovery of a black hole — the oldest ever detected — that shouldn’t even exist according to the current understanding of cosmic monsters so dense not even light can escape their gravitational pull. Born of a merger between two other black holes, GW190521 weighs in at 142 times the mass of our Sun and is the first “intermediate-mass” black hole ever observed, two consortiums […]

Small asteroid becomes closest ever seen passing Earth: NASA

WASHINGTON, United States (AFP) — An asteroid the size of an SUV passed 1,830 miles (2,950 kilometers) above Earth, the closest asteroid ever observed passing by our planet, NASA said Tuesday. If it had been on a collision course with Earth, the asteroid — named 2020 QG — would likely not have caused any damage, instead of disintegrating in the atmosphere, creating a fireball in the sky, or a meteor, NASA’s Jet Propulsion Laboratory (JPL) […]

Glaciers could have sculpted Mars valleys: study

PARIS, France (AFP) — The question of whether ancient life could have existed on Mars centres on the water that once flowed there, but new research published Monday suggests that many of the Red Planet’s valleys were gouged by icy glaciers not rivers. The study in Nature Geoscience, which comes amid a flurry of new Mars missions trying to discover if the now-barren planet ever hosted life, casts doubt on a dominant theory that the planet […]

James Webb Space Telescope launch pushed back to October 2021

WASHINGTON, United States (AFP) — NASA on Thursday postponed the launch of its $10 billion James Webb Space Telescope from March next year to October 31, 2021, blaming the pandemic and other technical challenges. The telescope, first conceived in the 1990s, was initially to be launched in the 2000s, but its main maker Northrop Grumman has faced numerous development problems that have doubled its cost. “Webb is the world’s most complex space observatory, and our […]
