Greenbelt, MD – NASA says as Chile and Argentina witnessed the total solar eclipse on December 14th, 2020, unbeknownst to skywatchers, a little tiny speck was flying past the Sun — a recently discovered comet.
This comet was first spotted in satellite data by Thai amateur astronomer Worachate Boonplod on the NASA-funded Sungrazer Project — a citizen science project that invites anyone to search for and discover new comets in images from the joint European Space Agency (ESA) and NASA Solar and Heliospheric Observatory, or SOHO.
Greenbelt, MD – NASA scientists identified a molecule in Titan’s atmosphere that has never been detected in any other atmosphere. In fact, many chemists have probably barely heard of it or know how to pronounce it: cyclopropenylidene, or C3H2. Scientists say that this simple carbon-based molecule may be a precursor to more complex compounds that could form or feed possible life on Titan.
Researchers found C3H2 by using a radio telescope observatory in northern Chile known as the Atacama Large Millimeter/submillimeter Array (ALMA).
Washington, D.C. – NASA’s first mission to demonstrate a planetary defense technique, the Double Asteroid Redirection Test (DART), will get one chance to hit its target, the small moonlet in the binary asteroid system Didymos.
The asteroid poses no threat to Earth and is an ideal test target: measuring the change in how the smaller asteroid orbits about the larger asteroid in a binary system is much easier than observing the change in a single asteroid’s orbit around the Sun.

Huntsville, AL – Astronomers have discovered a special kind of neutron star for the first time outside of the Milky Way galaxy, using data from NASA’s Chandra X-ray Observatory and the European Southern Observatory’s Very Large Telescope (VLT) in Chile.
Neutron stars are the ultra dense cores of massive stars that collapse and undergo a supernova explosion. This newly identified neutron star is a rare variety that has both a low magnetic field and no stellar companion.
The neutron star is located within the remains of a supernova – known as 1E 0102.2-7219 (E0102 for short) – in the Small Magellanic Cloud, located 200,000 light years from Earth.
Austin Peay State University physics student Deborah Gulledge named “Scientist of the Week” at National Lab
Clarksville, TN – The night sky is darker, the stars brighter, in Mount Pleasant, Tennessee. The rural town sits about an hour south of Nashville, where the heavens are dimmed by excessive light pollution, and as a girl, Deborah Gulledge became curious about the brilliant stars above her home.
“I was always interested in astronomy,” she said recently.
Austin Peay State University’s Osvaldo Di Paolo Harrison publishes fifth scholarly work on Hispanic crime fiction
Clarksville, TN – In 1978, the Spanish crime novelist José García Martínez-Calín created Gay Flower, a tough private detective reminiscent of Mikey Spillane’s Mike Hammer and Raymond Chandler’s Philip Marlow.
Flower’s adventures through the hardboiled underworld of 1940s Los Angeles helped revive crime fiction in Spain and Latin America, but Martínez-Calín is rarely mentioned in academic journals or invited to the genre’s many celebrated literary festivals, like Spain’s popular Semana Negra (Black Week).
American Heart Association reports Umbilical Cord Stem Cells show promise as Heart Failure Treatment
Circulation Research Journal Report
Dallas, TX – A heart failure treatment using umbilical cord-derived stem cells may lead to notable improvements in heart muscle function and quality of life, according to a new study published in Circulation Research, an American Heart Association journal.
“We are encouraged by our findings because they could pave the way to a non-invasive, promising new therapy for a group of patients who face grim odds,” said study corresponding author Fernando Figueroa, M.D., professor of medicine at the Universidad de los Andes in Chile.
Clarksville, TN – As part of the ongoing PeayClipse lecture series, Austin Peay State University faculty member Dr. J. Allyn Smith will present a talk titled, “The Secret Lives of Astronomers” at 7:00pm on July 22nd, 2017 during the City of Clarksville’s Movies in the Park Series, at McGregor Park.
The talk will take place prior to the evening’s featured film, “The Secret Lives of Pets.”

Moffett Field, CA – Scientists using NASA’s Kepler space telescope identified a regular pattern in the orbits of the planets in the TRAPPIST-1 system that confirmed suspected details about the orbit of its outermost and least understood planet, TRAPPIST-1h.
TRAPPIST-1 is only eight percent the mass of our sun, making it a cooler and less luminous star. It’s home to seven Earth-size planets, three of which orbit in their star’s habitable zone — the range of distances from a star where liquid water could pool on the surface of a rocky planet. The system is located about 40 light-years away in the constellation of Aquarius. The star is estimated to be between 3 billion and 8 billion years old.

Pasadena, CA – Few places are as hostile to life as Chile’s Atacama Desert. It’s the driest non-polar desert on Earth, and only the hardiest microbes survive there. Its rocky landscape has lain undisturbed for eons, exposed to extreme temperatures and radiation from the sun.
If you can find life here, you might be able to find it in an even harsher environment — like the surface of Mars. That’s why a team of researchers from NASA and several universities visited the Atacama in February. They spent 10 days testing devices that could one day be used to search for signs of life on other worlds. That group included a team from NASA’s Jet Propulsion Laboratory in Pasadena, California, working on a portable chemistry lab called the Chemical Laptop.
