Giant planets that developed early in a star system’s life could solve a mystery of why spiral structures are not observed in young protoplanetary discs, according to a new study by University of Warwick astronomers.

ANIMATION New research shows that sunspots and other active regions can change the overall solar emissions. The sunspots cause some emissions to dim and others to brighten; the timing of the changes also varies between different types of emissions. This knowledge will help astronomers characterize the conditions of stars, which […]

They searched for gas clouds, where there was a maser reinforcement of the OH […]

ANIMATION The Blue Ring Nebula, which perplexed scientists for over a decade, appears to be the youngest known example of two stars merged into one. In 2004, scientists with NASA’s space-based Galaxy Evolution Explorer (GALEX) spotted an object unlike any they’d seen before in our Milky Way galaxy: a large, faint blob of […]

On May 24, four European telescopes took part in the global effort to understand mysterious cosmic flashes. The telescopes captured flashes of radio waves from an extreme, magnetised star in our galaxy. All are shown in this illustration.

Magnetar-Powered Kilonova Blast. Credit: NASA, ESA, and D. Player (STScI)   ANIMATION Neutron-Star Collision Releases Puzzling Burst of Infrared Light In our infinite universe, stars can go bump in the night. When this happens between a pair of burned-out, crushed stars called neutron stars, the resulting fireworks show, called a kilonova, […]

The site for astronomy at Dome A. Credit: SHANG Zhaohui A research team led by Prof. SHANG Zhaohui from National Astronomical Observatories of the Chinese Academy of Sciences (NAOC) has proved that Dome A in Antarctica is the best site for optical astronomical observation on Earth. The study was published […]

An artist’s conception of HD 209458 b, an exoplanet whose atmosphere is being torn off at more than 35,000 km/hour by the radiation of its close-by parent star. This hot Jupiter was the first alien world discovered via the transit method, and the first planet to have its atmosphere studied. […]
