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...

Scientists validate theory of relativity on galactic level

Einstein's theory of general relativity is rather important when it's crucial to the modern understandings of the universe and technology like satellites. But does it hold up with something as vast as a galaxy? Thanks to researchers, we know the an...

First observed interstellar object is a speedy, cigar-shaped asteroid

Last month, astronomers running the Pan-STARRS 1 telescope in Hawaii spotted an intriguing object moving through our solar system and it became clear pretty quickly that the object, whether it was a comet or an asteroid, had come from outside of our...

Astronomers just measured a whole lot more than gravitational waves

A couple of weeks ago, the LIGO (Laser Interferometer Gravitational-Wave Observatory) and Virgo teams announced the detection of another set of gravitational waves -- the fourth since LIGO's first detection in September of 2015. The observations of t...

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.
