    The stacking of nearly three-quarters of a million spectra has unearthed a previously unknown component of the Galactic halo: a widely distributed, neutral, excited hydrogen layer that could harbour a sizeable proportion of the Milky Way’s baryons.

    The detection of gravitational waves is the culmination of many decades of persistent theoretical, observational and engineering work. While heralded as surprising, that the first detected wavescame from binary black holes was indeed theoretically expected.

    A faint galaxy has been detected in the very early Universe thanks to deep observations and a massive cluster gravitationally magnifying its emission. One out of only five such galaxies known, this detection constrains how the Universe was reionized.

    The discovery of several Kuiper belt objects (KBOs) with anomalous properties (they are blue-coloured, whereas KBOs of the same type are red, and they are all binaries) gives constraints on formation processes in the outermost region of the Solar System.

    Global-scale Rossby waves develop in planets’ atmospheres and influence their weather. Now, similar waves, driven by magnetism, are unambiguously detected on the Sun. They can possibly help the forecasting of solar activity and related space weather.

News & Comment

  • Comment |

    The scientific aims of the European Space Agency's International Gamma-Ray Astrophysics Laboratory are considerably extended because of its unique capability to identify electromagnetic counterparts to sources of gravitational waves and ultra-high-energy neutrinos.

    First the neutrinos arrived, then the burst of light: messengers of a cataclysmic event in the galaxy next door. Alak Ray recounts IAUS 331, a conference that celebrated the thirtieth anniversary of the supernova of a lifetime, SN1987A, and explored the critical role of asymmetry in the explosions, surroundings and initial conditions.

    The discovery of stars being formed within a galactic outflow confirms that supermassive black holes can enhance the growth of their host galaxies.

    The Sun is a magnetically active rotating star. Simultaneous observations with the STEREO and SDO space missions reveal solar analogues of planetary Rossby waves that will help forecast space weather.

Imprint of the past

The discovery of two old open clusters with a substantial number of stars rotating in alignment with each other could represent an imprint of the original angular momentum of the parent molecular cloud from which the stars formed. Our ideas about the turbulent births of stars would suggest that any signature of the momentum should have been wiped out, yet here we have a remnant.
