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.

Classifying Exoplanet Atmospheres Opens New Field of Study

An international team of researchers examined data for 25 exoplanets and found some links among the properties of the atmospheres, including the thermal profiles and chemical abundances in them.

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.

Billions of Starless Planets Haunt Dark Cloud Cradles

An international team has found about 100 planets floating freely in space rather than orbiting stars. Extrapolating this sample to the rest of the Milky Way Galaxy suggests that there are billions of undiscovered starless planets tumbling aimlessly through space.

Stellar “Ashfall” Could Help Distant Planets Grow

The world’s first 3D simulation simultaneously considering dust motion and growth in a disk around a young star has shown that large dust from the central region can be entrained by and then ejected by gas outflows, and eventually fall back onto the outer regions of the disk where it may enable planetesimal formation.

Fiery Dragon’s Breath May Scorch Young Planets

The star EK Draconis has belched out a stream of flaming gas. This is the first time such a supermassive filament eruption has been observed on a Sun-like star. Since, EK Draconis is similar to the Sun in size, but younger, this could indicate that the Sun also produced such supermassive ejections long ago. Large amounts of flaming gas from the Sun would have made the environment harsh for the planets, including the young Earth where life was first emerging.

Stellar Cocoon with Organic Molecules at the Edge of our Galaxy

For the first time, astronomers have detected a newborn star and the surrounding cocoon of complex organic molecules at the edge of our Galaxy, which is known as the extreme outer Galaxy. The discovery, which revealed the hidden chemical complexity of our Universe, appears in a paper in The Astrophysical Journal.
