The ExTrA facility, located at La Silla observatory, will consist of a near-infrared multi-object spectrograph fed by three 60-cm telescopes.
We only have one example of a planet with life: Earth. But within the next generation, it should become possible to detect signs of life on planets orbiting distant stars.
Extremeophiles and Extreme Environments
Bizarre creatures that go years without water. Others that can survive the vacuum of open space.
Toiling in barren rock fields in southern Spain under temperatures as high as 108 degrees Fahrenheit, a team from NASA's Ames Research Center, Honeybee Robotics, and Spain's Centro de Astrobiologia (CAB, INTA-CSIC) is changing dirt into data in a way that could one day be replicated on Mars.
While the Rosetta spacecraft orbits the 67P/Churyumov-Gerasimenko comet, the Philae lander, deployed from Rosetta on November 2014, has gathered data on the surface of the comet that indicate the potential existence of prebiotic organics during the early solar system.
We address the possibility that intelligent civilisations that destroy themselves could present signatures observable by humanity.
A new study shown that meteorite impacts on ancient oceans may have created nucleobases and amino acids.
The primary challenge of rocket propulsion is the burden of needing to accelerate the spacecraft's own fuel, resulting in only a logarithmic gain in maximum speed as propellant is added to the spacecraft.
Sugars of extraterrestrial origin have been observed in the interstellar medium (ISM), in at least one comet spectrum, and in several carbonaceous chondritic meteorites that have been recovered from the surface of the Earth.
Wright et al. 2014 have embarked on a search for advanced Karadashev Type III civilisations via the compilation of a sample of sources with extreme mid-IR emission and colours.
If advanced extraterrestrial civilizations choose to construct vast numbers of Dyson spheres to harvest radiation energy, this could affect the characteristics of their host galaxies.
