Scientists find evidence of a black hole at our galaxy’s center

Researchers have long suspected that a supermassive black hole lies in the center of our galaxy, and now they have strong evidence to support that suspicion. Using the Very Large Telescope -- an array of four individual telescopes stationed in the At...

ESO will upgrade its Very Large Telescope to hunt for exoplanets

The European Southern Observatory's Very Large Telescope is getting an upgrade. ESO signed an agreement with Breakthrough Initiatives, a program created to search for extraterrestrial intelligence, to modify its infrared instrument called VISIR (VLT...

Astronomers find three planets in Gliese 667C’s habitable zone

Astronomers find three planets in Gliese 667C's habitable zone

Astronomers have a good day when they detect one planet inside a star system's habitable zone. A mostly European team of researchers must be giddy, then, as it just found three of those ideally located planets around Gliese 667C. The group has combined existing observations from the ESO's Very Large Telescope with new HARPS telescope data to spot the trio of super-Earths, all of which could theoretically support liquid water. As long as the discovery holds up, it may have a big impact on exoplanetary research: it shows both that three super-Earths can exist in one system and that more than one survivable planet can orbit a low-mass star. We can only do so much with the findings when Gliese 667C is 22 light-years away, but it's good to learn that space could be more human-friendly than we once thought.

Infrared telescope can pick out the atmosphere on distant planets, smell what the aliens are smelling

Infrared telescope can pick out the atmosphere on distant planets, smell what the aliens are smelling

Astronomers in Chile using the European Southern Observatory's Very Large Telescope are now able to analyze the atmosphere on faraway planet Tau Bootis b. Using CRIRES, a supercooled infrared spectrograph bolted to the 'scope, the team was able to judge the size of the exoplanet -- and for the first time, take a reading of the atmosphere while not in transit. Historically, the only time researchers have been able to conduct atmospheric analysis is during the transit of its nearby star, which imprints the qualities of the atmosphere onto the light. The team found that Tau Bootis b is around six times the size of Jupiter, but its air is so thick with Carbon Monoxide that we'll have to look elsewhere to plan that expedition to the stars.
