Comet ISON Obituary|
December 1, 2013 | NBC News
“I do think that something emerged from the sun, but probably a very small nucleus or ‘rubble pile.’ and I fear that may have now dissolved.” Karl Battams, an astrophysicist at the Naval Research Laboratory.
IceCube Researchers Detect 28 Neutrinos
November 27, 2013 | National Science Foundation
“Researchers with the IceCube Collaboration have [...] observed 28 very high-energy neutrinos that constitute the first solid evidence for astrophysical neutrinos from cosmic accelerators. [...] IceCube is an [...] astrophysical telescope deployed deep in the Antarctic ice (from 1.4 to 2.4 km depth), but looks over the entire universe, detecting neutrinos coming through the Earth from the Northern skies, as well as from around the Southern skies,” Quoted from the National Science Foundation press release.

“On the left, bright green auroras appear to emanate from the largest glacier in Iceland as if it’s a volcano. On the right, clouds appear tinged with the green light reflecting from the auroras.” Quoted from the NASA image release.
Comet Ison is Visible to the Naked Eye|
November 21, 2013 | The Telegraph
“Comet Ison, first spotted a year ago, is now visible to the naked eye and will continue to brighten as it hurtles toward the sun.”
Granite on Mars?|
November 20, 2013 | Georgia Tech
“Researchers now have stronger evidence of granite on Mars and a new theory for how the granite – an igneous rock common on Earth — could have formed there. The findings suggest a much more geologically complex Mars than previously believed.” Quoted from the Georgia Tech press release.

Bedrock Map of Vesta Asteroid|
November 11, 2013 |
“This colorized map from NASA’s Dawn mission shows the types of rocks and minerals distributed around the surface of the giant asteroid Vesta. In this color scheme, red shows diogenite, a type of mineral thought to be formed through magmatic processes deep in the crust. Green shows howardite, a type of surface rock that is made of broken bits of different materials that are excavated, ejected and mixed by meteor impacts…..” Partial quote from the NASA image description.
An Asteroid with Six Comet-Like Tails|
November 11, 2013 | NASA
“This NASA Hubble Space Telescope set of images reveals a never-before-seen set of six comet-like tails radiating from a body in the asteroid belt, designated P/2013 P5.” Quoted from the NASA press release.
Radio Bursts From Beyond our Galaxy?|
November 10, 2013 | NASA
“Astronomers, including a team member from NASA’s Jet Propulsion Laboratory in Pasadena, Calif., have detected the first population of radio bursts known to originate from galaxies beyond our own Milky Way. The sources of the light bursts are unknown, but cataclysmic events, such as merging or exploding stars, are likely the triggers.” Quoted from the NASA press release.

Partial Solar Eclipse Visible on Sunday Morning from the East Coast|
November 1, 2013 | NASA
“The final event of 2013 is the most interesting eclipse of the year. It is one of the rare hybrid or annular/total eclipses in which some sections of the path are annular while other parts are total. The duality comes about when the vertex of the Moon’s umbral shadow pierces Earth’s surface at some locations, but falls short of the planet along other sections of the path.” Quoted from the NASA website.
People as far west as Pittsburgh should be able to see the eclipse. Observing from the east coast.

Observing Galaxies 100X Fainter than Ever Seen Before|
October 31, 2013 | NASA
“NASA’s Hubble, Spitzer and Chandra space telescopes are teaming up to look deeper into the universe than ever before. With a boost from natural “zoom lenses” found in space, they should be able to uncover galaxies that are as much as 100 times fainter than what these three great observatories typically can see.” Quoted from the NASA press release.
Coldest Place in the Universe|
October 30, 2013 | NASA
“At a cosmologically crisp one degree Kelvin (minus 458 degrees Fahrenheit), the Boomerang nebula is the coldest known object in the universe — colder, in fact, than the faint afterglow of the Big Bang, the explosive event that created the cosmos.” Quoted from the NASA press release.
Methane and Ethane Lakes on Saturn’s Moon Titan?|
October 25, 2013 | NASA
“With the sun now shining down over the north pole of Saturn’s moon Titan, a little luck with the weather, and trajectories that put the spacecraft into optimal viewing positions, NASA’s Cassini spacecraft has obtained new pictures of the liquid methane and ethane seas and lakes that reside near Titan’s north pole.” Quoted from the NASA image release.
Converting Methane into Diamonds?|
October 15, 2013 | National Geographic
Intense temperature, pressure and lightning storms on Saturn and Jupiter may be able to convert atmospheric methane into diamonds – producing a rain of diamonds on those planets.

“An international team of astronomers has discovered an exotic young planet that is not orbiting a star. This free-floating planet, dubbed PSO J318.5-22, is just 80 light-years away from Earth and has a mass only six times that of Jupiter. The planet formed a mere 12 million years ago—a newborn in planet lifetimes.” Quoted from the University of Hawaii press release.
