NASA - National Aeronautics and Space AdministrationPasadena, CA – A NASA airborne mission designed to transform our understanding of Earth’s valuable and ecologically sensitive coral reefs has set up shop in Australia for a two-month investigation of the Great Barrier Reef, the world’s largest reef ecosystem.

At a media briefing today at Cairns Airport in North Queensland, Australia, scientists from NASA’s COral Reef Airborne Laboratory (CORAL) mission and their Australian collaborators discussed the mission’s objectives and the new insights they expect to glean into the present condition of the Great Barrier Reef and the function of reef systems worldwide.

AAA says Gas Prices Drop to Close Out Labor Day Weekend

 

AAATampa, FL – The national average price for regular unleaded gasoline has dropped six consecutive days after rising for 16 straight days to close out August. Today’s national average is $2.20 per gallon. Gas prices started turning lower heading into the Labor Day weekend, which marks the unofficial end to the summer driving season.

Today’s national average is two cents less than a week ago and 18 cents less than a year ago but 8 cents more than one month ago. The year-on-year discount persists but has closed more than 30 cents in just 20 days.

NASA research shows moon Io’s atmosphere collapsing when in Jupiter’s Shadow

 

NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Jupiter’s volcanic moon Io has a thin atmosphere that collapses in the shadow of Jupiter, condensing as ice, according to a new study by NASA-funded researchers. The study reveals the freezing effects of Jupiter’s shadow during daily eclipses on the moon’s volcanic gases.

“This research is the first time scientists have observed this remarkable phenomenon directly, improving our understanding of this geologically active moon,” said Constantine Tsang, a scientist at the Southwest Research Institute in Boulder, Colorado. The study was published August 2nd in the Journal of Geophysical Research.

AAA reports Gas Prices Fall to Lowest Price Since April

 

AAAWashington, D.C. – National pump prices have fallen for 43 of the past 44 days, dropping 22 cents during this span. The national average price for regular unleaded gasoline sits at $2.21 per gallon, which is the lowest mark since April and the lowest price for this date since 2004.

Today’s price is five cents less than one week ago, 15 cents less than one month ago, and 56 cents less than the same date last year.

With abundant fuel supplies across the nation and declining crude oil costs, gas prices dropped in 47 states over the past week, led by double digit drops in several Midwestern states.

Price at the pump continues to fall.

Tennessee Democrats propose ’10 for TN’ to reduce Gun Violence

 

Tennessee Senate Democratic CaucusNashville, TN – Democrats in the Tennessee General Assembly released today a list of 10 proposals to combat gun violence in Tennessee in an email blast to supporters around the state.

“Inaction is no longer an option,” state Representative G.A. Hardaway said. “Moments of silence may demonstrate respect of lives lost, but we can truly honor the deaths of our loved ones, when we follow-up by enacting common sense laws to prevent more tragic killings of innocents.”

NASA’s Hubble Space Telescope photos find Dark vortex in Neptune’s Atmosphere

 

Written by Donna Weaver / Ray Villard
Space Telescope Science Institute

NASA - National Aeronautics and Space AdministrationBaltimore, MD – New images obtained on May 16th, 2016, by NASA’s Hubble Space Telescope confirm the presence of a dark vortex in the atmosphere of Neptune. Though similar features were seen during the Voyager 2 flyby of Neptune in 1989 and by the Hubble Space Telescope in 1994, this vortex is the first one observed on Neptune in the 21st century.

The discovery was announced on May 17th, 2016, in a Central Bureau for Astronomical Telegrams (CBAT) electronic telegram by University of California at Berkeley research astronomer Mike Wong, who led the team that analyzed the Hubble data.

This new Hubble Space Telescope image confirms the presence of a dark vortex in the atmosphere of Neptune. The full visible-light image at left shows that the dark feature resides near and below a patch of bright clouds in the planet's southern hemisphere. The full-color image at top right is a close-up of the complex feature. The vortex is a high-pressure system. The image at bottom right shows that the vortex is best seen at blue wavelengths.

AAA says Gas Prices Drop for Nine Straight Days

 

AAATampa, FL – Gas prices have fallen for nine consecutive days, reaching today’s average of $2.33 per gallon.

Gasoline demand remains on track to set a new all-time high for the 2016 summer driving season, however, crude oil remains relatively less expensive than recent years which is contributing to direct savings at the pump.

Drivers are saving a nickel per gallon on the week, but are paying five cents per gallon more on the month.

AAA reports Average U.S. Gas Prices Climb to 2016 High

 

AAATampa, FL – The national average price of gas reached a new 2016 high over the weekend, and today’s average of $2.38 per gallon is the most expensive average since September 2015.

Gas prices have moved higher by two cents per gallon on the week and 16 cents per gallon on the month.

Although pump prices have increased for 28 of the past 33 days, consumers continue to benefit from yearly savings and prices are down 42 cents per gallon compared to a year ago.

NASA’s Hubble Space Telescope and Gemini Telescope discover Huge Supermassive Black Hole

 

Written by Ray Villard
Space Telescope Science Institute

NASA - National Aeronautics and Space AdministrationBaltimore, MD – Astronomers have uncovered a near-record breaking supermassive black hole, weighing 17 billion suns, in an unlikely place: in the center of a galaxy in a sparsely populated area of the universe. The observations, made by NASA’s Hubble Space Telescope and the Gemini Telescope in Hawaii, may indicate that these monster objects may be more common than once thought.

Until now, the biggest supermassive black holes – those roughly 10 billion times the mass of our sun – have been found at the cores of very large galaxies in regions of the universe packed with other large galaxies.

This computer-simulated image shows a supermassive black hole at the core of a galaxy. The black region in the center represents the black hole’s event horizon, where no light can escape the massive object’s gravitational grip. The black hole’s powerful gravity distorts space around it like a funhouse mirror. Light from background stars is stretched and smeared as the stars skim by the black hole. (NASA, ESA, and D. Coe, J. Anderson, and R. van der Marel (STScI))
