In search for the furthest galaxies

teaserAn international research team is performing a program in search for the furthest galaxies in the universe. But distant objects are also very faint. For this reason, the search relies upon one of the strangest implications of general relativity: the amplification of light coming from remote bodies due to the gravitational effects of closer ones, the gravitational lensing effect. Calar Alto telescopes and instruments are contributing to this research…

The CALIFA survey unveils the evolution of galaxies in space and time

teaser small

The CALIFA survey, devoted to the study of galaxies in the near universe, has deduced for the first time the complete history of stellar formation for each one of the different regions of a set of one hundred galaxies. The researchers of this project, whose observations are performed at Calar Alto, have found that massive galaxies grew faster than lighter ones and, also, their inner central regions developed much earlier…

A “hot Jupiter” challenges planetary formation theories

teaserAn international scientific team has discovered an uncommon exoplanet that displays a too large radius in relation to its mass, what does not follow current theories on planet formation. This object, named WTS-1b, is considered a “hot Jupiter” due to its gaseous composition and its high temperature. Calar Alto has contributed to this finding…

The massive cluster in front of the Orion Nebula

teaser smallThe Orion nebula is one of the great wonders of the night sky. It is the closest place in our Galaxy where new massive stars are being born. For this reason, it is also an important test bench for star formation models. Recent discoveries are showing an unexpected complexity in this cosmic area, and Calar Alto has played a role in these new findings…
