website features news, resources, and discussion boards about LISA (the Laser Interferometer Space Antenna), a space-based gravitational-wave observatory that will allow us to detect gravitational waves from massive black-hole mergers in the centers of galaxies, from the ultra-compact binary systems in our own Galaxy, and from many other sources. A joint ESA and NASA mission, LISA will create revolutionary research opportunities in astrophysics and fundamental physics.

"El telescopio espacial Hubble de la NASA y de la Agencia Espacial Europea (ESA) ha captado una curiosa imagen de galaxias, que en su conjunto da una forma similar a la de una cara sonriente, informa la agencia espacial estadounidense."

"Gaia is an ambitious mission to chart a three-dimensional map of our Galaxy, the Milky Way, in the process revealing the composition, formation and evolution of the Galaxy. Gaia will provide unprecedented positional and radial velocity measurements with the accuracies needed to produce a stereoscopic and kinematic census of about one billion stars in our Galaxy and throughout the Local Group. This amounts to about 1 per cent of the Galactic stellar population. "
