MegaCam Canada-France-Hawaii Telescope image of Arp 227, also known as NGC 470 and NGC 474.

The large lenticular galaxy (NGC 474, left) is interacting with a smaller companion spiral galaxy (NGC 470, right). NGC 474's spectacular shells and tidal tails may be the result of a past merger with a smaller galaxy.

Canada-France-Hawaii Telescope image of Arp 189, also known as NGC 4651 or the Umbrella Galaxy.

The galaxy gets its nickname from the parasol-shaped feature to the right. It is a stellar stream made of debris from the remains of a tiny galaxy that was ripped apart by the large spiral galaxy.

[#JobAlert] L'IRAP recrute un #chercheur sur la #modélisation des topologies magnétiques des #étoiles de type naines M. Il s'agit d'un #CCD de 24 mois.

Ce projet vise à modéliser l'évolution des topologies magnétiques des naines M observées depuis 2019 grâce au spectropolarimètre proche infrarouge #SPIRou du #CFHT (CANADA-FRANCE-HAWAII TELESCOPE).

Postulez dès à présent et jusqu'au 15 mars 2026 sur le portail emploi du @cnrs : https://emploi.cnrs.fr/Offres/CDD/UMR5277-SANCHU-084/Default.aspx

[SPIRou + Wapiti => habitable exoplanet] Thanks to the #SPIRou infrared spectrometer on the #CFHT and the implementation of Wapiti, a new method for correcting #disturbances related to the #atmosphere, astronomers have detected an #exoplanet in the habitable zone of an M-type star—11.4 light-years from Earth.

Next-generation instruments will make it possible to determine whether this planet is rocky or not, and whether liquid water is part of its composition.
