Independent Reanalysis of the M87 Galactic Center Radio Observational Data

An independent reanalysis of the Event Horizon Telescope (EHT)’s observational data for the center of the elliptical galaxy M87 has produced images with different features, according to a new study. This study is part of the research process in modern science, in which observational data and analysis methods are open to the public and reviewed and discussed in various communities of researchers to produce more credible results.

Near-Sun Comet Roasted to Death

Astronomers using a fleet of world leading telescopes on the ground and in space have captured images of a periodic rocky near-Sun comet breaking apart. This is the first time such a comet has been caught in the act of disintegrating and could help explain the scarcity of such periodic near-Sun comets.

Yoyo Stars Responsible for Off-Center Bubbles

Astronomers have developed a new code to simulate the formation of a cluster of baby stars. Comparison with the well-known real case of the Orion Nebula shows that its off-center bubble of ionized gas was caused by a massive star that was pushed out of the newborn cluster but is now falling back in.

Supermassive Black Holes Inside of Dying Galaxies Detected in Early Universe

An international team of astronomers used a database combining observations from the best telescopes in the world, including the Subaru Telescope, to detect the signal from the active supermassive black holes of dying galaxies in the early Universe. The appearance of these active supermassive black holes correlates with changes in the host galaxy, suggesting that a black hole could have far reaching effects on the evolution of its host galaxy.

Astronomers reveal first image of the black hole at the heart of our galaxy

Astronomers have unveiled the first image of the supermassive black hole at the centre of our own Milky Way galaxy. This result provides overwhelming evidence that the object is indeed a black hole and yields valuable clues about the workings of such giants, which are thought to reside at the centre of most galaxies. The image was produced by a global research team called the Event Horizon Telescope (EHT) Collaboration, using observations from a worldwide network of radio telescopes.

Missing-Link Black Hole Found Lurking in Plain Sight

An international research team has discovered a supermassive black hole in the early Universe that could provide the missing link in the evolution of quasars, some of the brightest objects in space. This result is important for understanding the evolution of supermassive black holes, like the one hiding at the center of our own Milky Way Galaxy.

Most Distant Galaxy Candidate Yet

An international astronomer team has discovered the most distant galaxy candidate to date, named HD1, which is about 13.5 billion light-years away. This galaxy candidate is one of the targets of the James Webb Space Telescope launched late last year. If observations with the James Webb Space Telescope confirm its exact distance, HD1 will be the most distant galaxy ever recorded.

Prenatal Protoplanet Upends Planet Formation Models

An international research team has discovered a new planet so young that it has yet to emerge from the womb of matter where it is forming. This is the youngest protoplanet discovered to date. It’s location and the surrounding patterns of matter suggest that an alternative method of planet formation may be at work. This discovery could help to explain the histories and features of extrasolar planets seen around other stars.

Deep Neural Network to Find Hidden Turbulent Motion on the Sun

Scientists developed a neural network deep learning technique to extract hidden turbulent motion information from observations of the Sun. Tests on three different sets of simulation data showed that it is possible to infer the horizontal motion from data for the temperature and vertical motion. This technique will benefit solar astronomy and other fields such as plasma physics, fusion science, and fluid dynamics.
