    The detection of a metal-polluted G star in a binary system with an invisible X-ray source offset from the centre of a supernova remnant leads to the suggestion that this was the progenitor pair behind a core-collapse supernova in RCW 86.

    The authors put together measurements of ions and neutral atoms from Cassini and the two Voyagers and find that the heliosphere responds quickly (with a lag of 2–3 years) to the solar cycle and that it is bubble-shaped and not tail-shaped, as usually schematized.

    Cassini’s camera observed Titan from orbit at different angles (0–166°) and found that the planet looks brighter towards the night than at midday. This effect, linked to the scattering properties of Titanian haze, can also be present in exoplanets.

    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.

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.

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.

See Corsaro et al. 1, 0064 (2017).
