(Phys.org)—Using NASA's prolonged Kepler mission, known as K2, astronomers have discovered a new Neptune-sized planet in a binary star system in the Hyades open cluster. The newly found exoworld, designated K2-nnnA b, is ...
(Phys.org)—Astronomers have detected a new low-mass eclipsing binary star in an open cluster named NGC 2632, better known as the Beehive Cluster (or Praesepe). The newly identified binary, designated PTFEB132.707+19.810, ...
(Phys.org)—Astronomers have determined chemical abundances of several elements for six giant stars of a recently discovered stellar cluster known as Gaia1. The results, available in a paper published June 5 on arXiv.org, ...
Our sun vibrates due to pressure waves generated by turbulence in its upper layers (the layers dominated by convective gas motions). Helioseismology is the name given to the study of these oscillations, which can shed light ...

(Phys.org)—Astronomers from Heidelberg University in Germany and the Observatory of Strasbourg in France have detected nine new open star clusters within 1,500 light years from the sun. The discovery, presented in a paper ...
Messier 18 was discovered and catalogued in 1764 by Charles Messier—for whom the Messier Objects are named—during his search for comet-like objects. It lies within the Milky Way, approximately 4600 light-years away in ...

(Phys.org)—An international team of astronomers, led by Rodolfo Smiljanic of the Nicolaus Copernicus Astronomical Center in Toruń, Poland, has detected two new giant lithium-abundant stars in an old open cluster named ...
Young massive star clusters are systems of stars with more than about ten thousand solar-masses of material and ages less than about one hundred million years that are gravitationally bound together. In these clusters the ...

(Phys.org)—When a giant cloud of molecular gas condenses, star clusters are born. It may sound simple but the formation of star clusters is a very complex process, not yet completely understood by scientists. By peering ...
