An article published in the journal “Nature” describes the discovery of a super-Earth called LHS 1140b. A team led by Jason Dittmann of the Harvard-Smithsonian Center for Astrophysics used the HARPS instrument installed on ESO’s 3.6-meter telescope in La Silla, Chile, to study that exoplanet after identifying it with the MEarth-South telescope at Cerro Tololo Inter-American Observatory. Its location in ​​its solar system’s habitable zone makes it particularly interesting.

An article published in the journal “Monthly Notices of the Royal Astronomical Society” describes a research on dark matter filaments that connect two galaxies. A team of astronomers led by Mike Hudson of the University of Waterloo in Canada exploited a weak gravitational lensing effect to create an image that shows even if indirectly a kind of dark matter bridge between two galaxies.

A little while ago Orbital ATK’s Cygnus spacecraft blasted off atop an Atlas V rocket from Cape Canaveral. After about 21 minutes it successfully separated from the rocket’s last stage went en route to its destination. This is its seventh official mission, called Orbital-7 or simply Orb-7 but also CRS OA-7, to transport supplies to the International Space Station for NASA.
