Kelly-Hubble Telescope 11.09.14 - Video

On November 20, Lilly's Bistro at 1147 Bardstown Road will be hosting Hubble Rumble in the Hood, a special dining event celebrating Edwin Hubble's 125th Birthday. Hubble Rumble in the Hood is a collaboration between Lilly's and the University of Louisvilles Gheens Science Hall and Rauch Planetarium.

Yes, that Edwin Hubble, of the Hubble Telescope. The American astronomer actually lived in Louisville, on Everett Avenue, near Cherokee Triangle in the Highlands. Hubble also taught Spanish, physics and math at New Albany High School before he decided to become an astronomer at 25, at which point he left Kentuckianafor the University of Chicago.

Hubble Rumble in the Hood (November 20, 11 a.m. - 3 p.m. for lunch and 5 p.m. - 10 p.m. for dinner) will allow diners to choose from "specialty cocktails like the Cosmic Cosmopolitan, the Guiness Black Hole and Hubbles Bubbles, or culinary treats such as Lillys Crescent Moon Caramelized Onion Tart and Hanger Steak with Jedi Sauce and Death Star Gnocchi." A percentage of all lunch and dinner sales will go towards bringing an Owsley Brown II Portable Planetarium to Bloom Elementary School.

Telescopes will be set up in front of Lilly's during dinner hours to allow patrons to observe the sky, with telescopes and viewing tips provided by the Louisville Astronomical Society. Educators will be on hand during dinner hours to talk about Hubble's influence and impact on astronomy. Reservations can be made by calling 502-451-0447, but are not required.

Illuminate the universe and you'll see more beauty than you could ever imagine.

That's exactly what a cosmic phenomenon, called a light echo, does.

This Hubble image to the right was taken in February, 2004 and is a consequence of the revealing power of the light echo.

This isn't just a pretty image, though. It's one of many that the Hubble has caught that actually teaches us something new about how our universe works.

We think it's one of the most stunning scientific images we've seen from the telescope because astronomers had to wait nearly two years for it.

That's because before 2002, the only thing we could see in this region was a supergiant star.

But in January 2002, the star, located 20,000 light years from Earth, gave off a blindingly bright pulse of light.

For the brief period of time the pulse lasted, the star was the most luminous star in our galaxy, shining at 600,000 times brighter than our sun.

The star eventually faded, but the light it emitted continued to travel outward, illuminating the star's surrounding nebula, as shown in the animation below.

Using NASAs Hubble Space Telescope, astronomers have completed the largest and most sensitive visible-light imaging survey of the debris disks surrounding nearby stars. These dusty disks, likely created by collisions between leftover objects from planet formation, were imaged around stars as young as 10 million years old and as mature as more than 1 billion years old.

The research was conducted by astronomers from NASAs Goddard Space Center with the help of the University of Arizonas Steward Observatory. The survey was led by Glenn Schneider, the results of which appeared in the Oct. 1, 2014, issue of The Astronomical Journal.

We find that the systems are not simply flat with uniform surfaces, Schneider said. These are actually pretty complicated three-dimensional debris systems, often with embedded smaller structures. Some of the substructures could be signposts of unseen planets.

In addition to learning much about the debris fields that surround neighboring stars, the study presented an opportunity to learn more about the formation of our own Solar System.

Its like looking back in time to see the kinds of destructive events that once routinely happened in our solar system after the planets formed, said Schneider.

Once thought to be flat disks, the study revealed an unexpected diversity and complexity of dusty debris structures surrounding the observed stars. This strongly suggest they are being gravitationally affected by unseen planets orbiting the star.

Alternatively, these effects could result from the stars passing through interstellar space. In addition, the researchers discovered that no two disks of material surrounding stars were alike.

The astronomers used Hubbles Space Telescope Imaging Spectrograph to study 10 previously discovered circumstellar debris systems, plus MP Mus, a mature protoplanetary disk that is comparable in age to the youngest of the debris disks.

NASAs Hubble Space Telescope has detected a faint light, described as the ghostly glow of stars that were ejected from ancient galaxies, which themselves are believed to have been ripped apart by gravitational forces billions of years ago. The light is believed to emerge from inside a collection of about 500 galaxies known as Abell 2744, about four billion light-years away.

According to astronomers, the stars in this group of galaxies -- named Pandoras Cluster -- are scattered and their light has helped scientists gather evidence, suggesting that as many as six galaxies were torn to pieces inside the cluster over a period of six billion years. Astronomers expect the new findings to help them better understand the evolution of galaxy clusters.

The results are in good agreement with what has been predicted to happen inside massive galaxy clusters, Mireia Montes of The Instituto de Astrofsica de Canarias (IAC), Santa Cruz de Tenerife, Spain, and the lead author of the study published in the Astrophysical Journal earlier this month, said in a statement.

The astronomers estimate that the combined light of about 200 billion outcast stars contributes about 10 percent of the clusters brightness. According to data provided by Hubble, these stars have significant amounts of heavier elements, such as oxygen, carbon and nitrogen.The gravity in galaxy clusters deflects light passing through them, magnifying, brightening and distorting light in a phenomenon called gravitational lensing, which is used by astronomers to blow up the images of remote galaxies.

According to NASA, Abell 2744 is a target in the Frontier Fields program, a three-year-long mission that combines Hubble and NASAs other observatories to study massive galaxy clusters for answers to the universe.

NASAs Hubble Telescope Spots Ghost Light From Dead Galaxies

It appears that spooky goings-on over the Halloween period are not just confined to Earth. The Hubble Space Telescope has made its own ghostly discovery by capturing the ghost light from dead galaxies ripped apart billions of years ago.

The ghost light comes from stars that were ejected from ancient galaxies ripped apart by gravity. These orphaned stars are no longer attached to any one galaxy, and instead wander between nearby galaxies.

But dont worry, they wont be wandering over here any time soon. This epic galaxy death happened over four billion light years away in a large group of galaxies known as the Pandora cluster, or Abel 2744.

Hubble astronomers have turned detective and used the ground-breaking images to deduce the dead galaxies last movements. Their evidence suggests that as many as six galaxies were torn apart over a time period of six billion years.

These galaxies were probably about the same size as our own Milky Way. Such smaller galaxies would have had no chance as they plunged through the centre of the galaxy cluster where gravitational tidal forces are at their strongest.

The source of the ghost light is actually coming from an estimated200 billion outcast stars. They make up about 10% of the total light being emitted by the Pandora cluster.

Measurements taken by Hubble show that these stars are rich inheavier elements like oxygen, carbon, and nitrogen. Thats a tell-tale sign that these are second or third-generation stars which have been enriched by elements that were originally created at the heart of the universes first-generation stars.

This kind of on-going star formation is most commonly found in spiral galaxies, which is where we think these orphan stars originated.

Well for a start its impressive that we even spotted these stars.
