Scientists are a step closer to understanding the inner-workings of the universe following the laying of the first stone, and construction starting on the world's largest optical and infrared telescope. With a main mirror 39 meters in diameter, the Extremely Large Telescope (ELT), is going to be, as its name suggests, enormous. Unlike any other before it, ELT is also designed to be an adaptive telescope and has the ability to correct atmospheric turbulence, taking telescope engineering to another level.

"What Lies Beneath is Breathtaking!" --NASA Peers Below Jupiter's Clouds and Sees a Whole New Complex, Gigantic and Turbulent World

The early science results from NASA’s Juno mission to Jupiter portray the largest planet in our solar system as a complex, gigantic, turbulent world, with Earth-sized polar cyclones, plunging storm systems that travel deep into the heart of the gas giant, and a mammoth, lumpy magnetic field that may indicate it was generated closer to the planet’s surface than previously thought.

Astronomers Observe Birth of a Massive 'LIGO-Sized' Black Hole in Realtime --"First Ever Witnessed" (VIDEO)

Astronomers have watched as a massive, dying star was likely reborn as a black hole. It took the combined power of the Large Binocular Telescope (LBT), and NASA's Hubble and Spitzer space telescopes to go looking for remnants of the vanquished star, only to find that it disappeared out of sight. It went out with a whimper instead of a bang: The star, which was 25 times as massive as our sun, should have exploded in a very bright supernova. Instead, it fizzled out -- and then left behind a black hole.

"What we've learned so far is earth-shattering. Or should I say, Jupiter-shattering," said Bolton, Juno's principal investigator. "Discoveries about its core, composition, magnetosphere, and poles are as stunning as the photographs the mission is generating."

FRB's --"Strange Signals from Alien Worlds" (WATCH Today's 'Galaxy' Stream)

Fast Radio Bursts are millisecond-duration pulses of unknown origin that were discovered by pulsar astronomers in 2007. A decade on from the discovery, with only 20 further bursts currently known, fast radio bursts remain enigmatic sources which parallel the early days of gamma-ray burst astronomy in the early 1970s. Each burst lasts for a fraction of a second releasing more energy in that time than the sun will radiate in 10,000 years. Recent studies (see below) speculated that these bursts could come from alien radio transmitters.

Hyper-Growth Galaxies from Early Universe --"Formed in Unusual Regions of the Cosmos"

An international team of astronomers has discovered a new kind of galaxy which, although extremely old--formed less than a billion years after the Big Bang--creates stars more than a hundred times faster than our own Milky Way. "Very likely it is not a coincidence to find these productive galaxies close to bright quasars. Quasars are thought to form in regions of the universe where the large-scale density of matter is much higher than average. Those same conditions should also be conducive to galaxies forming new stars at a greatly increased rate," added Fabian Walter, of the Max Planck Institute for Astronomy.

Cassini Solstice Mission --NASA Observes Saturn's Summer Close Up for the First Time

NASA's Cassini spacecraft still has a few months to go before it completes its mission in September, but the veteran Saturn explorer reaches a new milestone today. Saturn's solstice—that is, the longest day of summer in the northern hemisphere and the shortest day of winter in the southern hemisphere—arrives today for the planet and its moons.

NASA Tracks Strange Supermassive Black Hole Moving Away From Elliptical Galaxy's Center (VIDEO)

Supermassive black holes are generally stationary objects, sitting at the centers of most galaxies. However, using data from NASA's Chandra X-ray Observatory and other telescopes, astronomers recently hunted down what could be a supermassive black hole that may be on the move.

"The Day the Dinosaurs Died" -- Chicxulub Asteroid Impact Equivalent to 10 Billion Hiroshima Bombs Hit Worst Possible Place on Earth (WATCH Today's 'Galaxy'Stream)

Scientists drilled into the Chicxulub crater buried underneath the Yucatán Peninsula recovered rocks from under the Gulf of Mexico that were hit by an asteroid 66 million years ago creating the niche that made the rise of homo sapiens possible. The 15 km-wide asteroid could not have hit a worse place on Earth. "All these fossils occur in a layer no more than 10cm thick," said palaeontologist Ken Lacovara. "They died suddenly and were buried quickly. It tells us this is a moment in geological time. That's days, weeks, maybe months. But this is not thousands of years; it's not hundreds of thousands of years. This is essentially an instantaneous event."

Mystery in Galaxy Cygnus A --"Unknown Object of Extraordinary Brightness Discovered"

"To our surprise, we found a prominent new feature near the galaxy's nucleus that did not appear in any previous published images. This new feature is bright enough that we definitely would have seen it in the earlier images if nothing had changed," said Rick Perley Rick of the National Radio Astronomy Observatory (NRAO). "That means it must have turned on sometime between 1996 and now," he added.
