Astrônomos usaram dados de raios X de explosões extragalácticas para medir distâncias até nuvens de poeira nos braços espirais da Via Láctea, descobrindo que eles podem se estender 10% além do que se acreditava.
O telescópio Euclid da ESA descobriu 31 quasares, incluindo dois dos mais antigos já observados, que brilhavam com a intensidade de um trilhão de sóis quando o universo tinha apenas 670 milhões de anos. Esses achados ajudam a entender a formação de buracos negros supermassivos.
Smithsonian Starstruck offers a 40-minute VR journey through space, visiting the Sun, a black hole, and exoplanets. The experience, available in Washington D.C. with plans for expansion, uses HTC Vive headsets and a virtual guide to explore cosmic phenomena like the Big Bang and stellar nurseries.
Estudo do Observatório Europeu Austral (ESO) alerta que megaconstelações de satélites podem ter "consequências devastadoras para a astronomia". O número de dispositivos em órbita não deveria passar de 100 mil para preservar a capacidade de observar o céu.
New research from the European Southern Observatory (ESO) warns that the planned launch of 1.7 million satellites could have devastating consequences for astronomy, making the night sky up to four times brighter and obscuring celestial views. The study calls for a limit of 100,000 satellites to preserve astronomical observation.
British barbecue culture is transforming with the rise of high-end grills costing over £1,000. Driven by a desire for special experiences and year-round use, these premium devices are shifting from simple grilling to 'gastronomy,' becoming status symbols and investment pieces.
Fotógrafo brasileiro Rodrigo Guerra teve sua imagem inspirada em Van Gogh selecionada pela Nasa. A foto, tirada em Cascavel, Paraná, retrata a Lua, Vênus, Urano e a constelação Sete Irmãs, recriando a famosa pintura 'Noite Estrelada'.
Une nouvelle étude suggère que la Terre pourrait échapper à l'engloutissement par le Soleil lors de son expansion en géante rouge. Les calculs révisés indiquent que la dissipation des marées stellaires est plus faible, favorisant l'éloignement de la Terre.
Archaeologists have discovered a 5,000-year-old monument near Stonehenge in Wiltshire, predating the famous landmark by 500 years. The site features two large postholes aligned with the sun, suggesting early solar alignments and ceremonial traditions.
Pesquisa liderada pela USP encontrou uma nova forma de identificar estrelas que engoliram planetas: a análise da abundância de berílio. A estrela HD 129171 apresentou maior quantidade desse elemento, indicando a ingestão de material rochoso.
A Cambridge University astrophysics professor, Wyn Evans, alleges the Institute of Astronomy tolerates misogyny and bullying, and retaliated against whistleblowers. The university denies the claims, calling them a "vendetta" against the director.
Yaklaşık 20 yıldır uzaydan gelen gizemli radyo sinyallerinin kaynağı olan ASKAP J1745-5051 yıldız sistemi keşfedildi. Bir beyaz cücenin komşu yıldızdan madde çektiği sistemde, nova patlamaları ve manyetik alan etkileşimi radyo sinyallerini oluşturuyor.
Dai Liang, a cosmology and astrophysics specialist who received a 2021 Sloan Research Fellowship, has returned to China to take a professorship at Fudan University in Shanghai.
Two women in ancient China, Zhang Xiugu and another unnamed figure, defied societal restrictions to make significant contributions to medicine, astronomy, and mathematics. Zhang Xiugu, living around 1500 years ago, is noted for early work in pathological anatomy.
A 1970s Australian radio astronomy project, led by Dr. John O’Sullivan, aimed to detect signals from exploding black holes but failed. However, the mathematical techniques developed, including the Fast Fourier Transform, solved multipath interference issues, leading to the invention of Wi-Fi and influencing Bluetooth.
The Experience Macao Roadshow in Madrid offered visitors interactive activities, cultural performances and gastronomy highlighting the Asian territory’s tourism appeal.
