Researchers led by a Rutgers University-New Brunswick astrophysicist, who looked deeply into space at a period known as “Cosmic Noon” about 2 billion to 3 billion years after the Big Bang, have found that a special class of galaxies were busy experiencing their first major burst of star formation.

The discovery is important, scientists said, because it will answer questions about how galaxies grow and evolve, providing key insights into the early stages of galaxy development and the overall history of the universe. 

A team of physicists from the University at Albany has proposed scientifically rigorous methods for documenting and analyzing Unidentified Anomalous Phenomena (UAP) building upon the work of numerous past and present researchers in the field.

University of Hawaiʻi researchers discovered a new type of cosmic explosion, extreme nuclear transients, triggered when massive stars are torn apart by supermassive black holes.

The core portion of NASA’s Nancy Grace Roman Space Telescope has successfully completed vibration testing, ensuring it will withstand the extreme shaking experienced during launch. Passing this key milestone brings Roman one step closer to helping answer essential questions about the role of dark energy and other cosmic mysteries.

The host star, TOI-6894, is a red dwarf with only 20% the mass of the Sun, typical of the most common stars in our galaxy. Until now, such low-mass stars were not thought capable of forming or retaining giant planets. But as published in Nature Astronomy, the unmistakable signature of a giant planet — TOI-6894b — has been detected in orbit around this tiny star.

The University of Warwick and UCL astronomers, as part of a global collaboration including partners in Chile, USA, and Europe, have discovered the smallest known star to host a transiting giant planet, which should not exist under leading planet formation theories. 

Most stars in the Universe exist in binary or multiple star systems, where the presence of close-in companion stars in such systems can adversely influence the formation and orbital stability of planets around one of the stars. An international team of astrophysicists led by Professor Man Hoi LEE from the Department of Earth Sciences and the Department of Physics at The University of Hong Kong (HKU) and Mr Ho Wan CHENG, an MPhil student in his team, has confirmed the existence of a planet in an unprecedented retrograde orbit (moving in the opposite direction to the binary’s orbit) in the nu Octantis (nu Octantis) binary star system and revealed the role of binary star evolution in the origin of this planet. The findings have been published in the journal Nature.
