The Event Horizon Telescope (EHT) Collaboration has unveiled fresh images of M87*, the supermassive black hole in the galaxy Messier 87, using data collected in April 2018. These observations, which involved the newly operational Greenland Telescope and a significantly enhanced recording rate across the array, provide a new perspective on the source compared to the …

Large portions of the clouds of …
Astronomers, utilizing data from the powerful Atacama Large Millimeter/submillimeter Array (ALMA), have discovered ring and spiral structures in very young planetary disks, demonstrating that planet formation may begin much earlier than previously thought. The international team captured images of Class 0 and Class I planetary disks, which are much younger than the previously …
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have observed a disk bending wave in BRI 1335-0417, the oldest known spiral galaxy at over 12 billion years old. This unprecedented observation reveals the galaxy’s dynamic growth patterns, showcasing a vertically oscillating disk movement similar to ripples on a pond. The study marks the first time …
A team of astronomers has captured a new snapshot of an ancient galaxy, BRI 1335-0417, which is over 12 billion years old and the furthest known spiral galaxy in the Universe. The study, published in Monthly Notices of the Royal Astronomical Society, reveals crucial information about the formation of this galaxy and the origins of …
The trans-Neptunian dwarf planet Eris is tidally locked to its small moon Dysnomia. Recently obtained bounds on the mass of Dysnomia demonstrate that Eris must be unexpectedly dissipative (‘squishy’) for it to have despun over the age of the Solar System. New research shows that Eris must have differentiated into an ice shell and rocky …
