Dutch Scientists Found Youngest Protoplanetary Disk Ever

  Planets form in disks of gas and dust around a star in the making, but when and how such protoplanetary disks form is still a mystery. Now, by using the ALMA radio telescope, a team of astronomers, led by the Leiden PhD student Nadia Murillo and professor Ewine Dishoeck, has found the youngest protoplanetary disk [continue reading]

"Old Young" Stars in the Eagle Nebula

  The early stages of a star’s life are critical both for the star and for any future planets that might develop around it. The process of star formation, once thought to involve just the simple coalescence of material under the influence of gravity, actually entails a complex series of stages, with the youngest stars [continue reading]

Evidence for Exoplanet Under Construction Uncovered

  This news item was released during my holiday. You probably heard of it, but in the case you didn’t, here it is.   Astronomers using NASA’s Hubble Space Telescope have found compelling evidence of a planet forming 7.5 billion miles away from its star, a finding that may challenge current theories about planet formation. [continue reading]
