Astronomers have found a molecular cloud that is collapsing to form two massive protostars that will eventually become a binary star system. This observations show that binary stars form together.

The Hong Kong University of Science and Technology (HKUST) (HKUST) will build a new kind of camera using a new approach of quantum optics. The camera is set to help solve unanswered questions in astrophysics and cosmology, such as how light originates and varies around the black hole, in the hope of deciphering information emitted from there.

Researchers have detected a radio signal from abundant interstellar dust in MACS0416_Y1, a galaxy 13.2 billion light-years away in the constellation Eridanus. Standard models can’t explain this much dust in a galaxy this young, forcing us to rethink the history of star formation.

Researchers spotted the formation sites of planets around a young star resembling our Sun. Two rings of dust around the star, at distances comparable to the asteroid belt and the orbit of Neptune in our Solar System, suggest that we are witnessing the formation of a planetary system similar to ours.

A team of astronomers has discovered 83 quasars powered by supermassive black holes (SMBHs) in the early Universe. This increases the number of black holes known at that epoch considerably, and reveals, for the first time, how common SMBHs were early in the Universe's history.

A team of experts in nuclear fusion and astronomy has computed high-accuracy atomic data for analyzing light from a kilonova, a birth place of heavy elements. They found that their new data set could predict kilonovae brightness with much better accuracy than before. This aids our understanding of the cosmic origins of heavy elements.

Astronomers have detected a stealthy black hole from its effects on an interstellar gas cloud. This intermediate mass black hole is one of over 100 million quiet black holes expected to be lurking in our Galaxy. These results provide a new method to search for other hidden black holes and help us understand the growth and evolution of black holes.

New study finds dark matter may scatter against each other only when they hit the right energy, which could explain why galaxies from the smallest to the biggest have the shapes they do.

Astronomers have unveiled the origins of two different gas streams from a baby star. Using ALMA, they found that the slow outflow and the high speed jet from a protostar have misaligned axes and that the former started to be ejected earlier than the latter. These indicate that streams were launched from different parts of disk around the protostar.

Astronomers using ALMA have detected various complex organic molecules around the young star V883 Ori. A sudden outburst from this star is releasing molecules from the icy compounds in the planet forming disk.

“It’s not that Newton’s theory was wrong,” says Professor Barry Barish, an experimental physicist from the California Institute of Technology and University of California, Riverside. “It was just incomplete and didn’t describe all of nature,” he says.

For the first time ever, astronomers have detected a 1.3 km radius body at the edge of the Solar System. Kilometer sized bodies like the one discovered have been predicted to exist for more than 70 years. These objects acted as an important step in the planet formation process between small initial amalgamations of dust and ice and the planets.
Newly Developed simultaneous multi-color camera MuSCAT2
17 Dec 2018
A Japan-Spain team has developed a powerful 4-color simultaneous camera named MuSCAT2 for the 1.52-m Telescopio Carlos Sánchez at the Teide Observatory. The instrument aims to find transiting exoplanets, including Earth-like habitable planets orbiting stars near the Sun, in collaboration with NASA’s Transiting Exoplanet Survey Satellite.

Distribution of discovered exoplanet orbits
04 Dec 2018
An international team of astronomers using a combination of ground and space based telescopes have reported more than 100 extrasolar planets (here after, exoplanets) in only three months. These planets are quite diverse and expected to play a large role in developing the research field of exoplanets and life in the Universe.

Based on computer simulations and new observations from ALMA, researchers have found that the rings of gas surrounding active supermassive black holes are not simple donut shapes. Instead, gas expelled from the center interacts with infalling gas to create a dynamic circulation pattern, similar to a water fountain in a city park.

ALMA has tuned in another new channel for signals from space. Using its highest frequency receivers yet, researchers obtained 695 radio signatures for various molecules in the direction of a massive star forming region. These first results from the ALMA Band 10 receivers developed in Japan ensure a promising future for high frequency observations.

An international research team discovered the first recorded "ultra-stripped supernova," a rare, faint supernova that is believed to play a role in the formation of binary neutron star systems. These will advance our understanding of a variety of topics ranging from gravitational waves to the origin of precious metals like gold and platinum.
