Joe Biden-Kamala Harris Administration announces Initial Actions to Address the Gun Violence Public Health Epidemic

 

The White HouseWashington, D.C. – The Joe Biden-Kamala Harris Administration is announcing six initial actions to address the gun violence public health epidemic. The recent high-profile mass shootings in Boulder – taking the lives of 10 individuals – and Atlanta – taking the lives of eight individuals, including six Asian American women – underscored the relentlessness of this epidemic.

Gun violence takes lives and leaves a lasting legacy of trauma in communities every single day in this country, even when it is not on the nightly news.

NASA’s Solar Dynamics Observatory sees First Nanoflare on the Sun

 

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – NASA reports that researchers may have found the long-sought “nanoflares” thought to heat the solar corona to its incredible temperatures.

A new study published in Nature Astronomy marks the first time researchers have captured the full lifecycle of a putative nanoflare – from bright origins to blistering demise.

Nanoflares are tiny eruptions on the Sun, one-billionth the size of normal solar flares. Eugene Parker – of Parker Solar Probe fame – first predicted them in 1972 to solve a major puzzle: the coronal heating problem.

NASA’s Lucy Mission Passes Critical Mission Milestone

 

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – NASA’s Lucy mission last week marked the completion of a major milestone on the path to spacecraft assembly, test, and launch operations.

The Systems Integration Review ensured segments, components, and subsystems, scientific instrumentation, electrical and communication systems, and navigation systems are on schedule to be integrated into the system. It confirmed that facilities, support personnel, and plans and procedures are on schedule to support integration.

NASA’s Curiosity Rover sees Earth, Venus from Mars

 

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Curiosity Mars rover occasionally stops to stargaze. Recently, it captured a shot of Earth and Venus in the Red Planet’s night sky.

Curiosity aimed its Mast Camera, or Mastcam, at the heavens about 75 minutes after sunset on June 5th, 2020, the 2,784th Martian day, or sol, of the mission. A two-image twilight panorama reveals Earth in one frame and Venus in the other.

Both planets appear as mere pinpoints of light, owing to a combination of distance and dust in the air; they would normally look like very bright stars.

NASA’s New Horizons Conducts the First Interstellar Parallax Experiment

 

NASA - National Aeronautics and Space AdministrationWashington, D.C. – For the first time, a spacecraft has sent back pictures of the sky from so far away that some stars appear to be in different positions than we’d see from Earth. 

More than four billion miles from home and speeding toward interstellar space, NASA’s New Horizons has traveled so far that it now has a unique view of the nearest stars.

“It’s fair to say that New Horizons is looking at an alien sky, unlike what we see from Earth,” said Alan Stern, New Horizons principal investigator from Southwest Research Institute (SwRI) in Boulder, Colorado.

NASA reports Arctic Regions Ice Melts speed up Freshwater Depletion

 

NASA - National Aeronautics and Space AdministrationPasadena, CA – Seven of the regions that dominate global ice mass losses are melting at an accelerated rate, a new study shows, and the quickened melt rate is depleting freshwater resources that millions of people depend on.

The impact of melting ice in Greenland and Antarctica on the world’s oceans is well documented. But the largest contributors to sea level rise in the 20th century were melting ice caps and glaciers located in seven other regions: Alaska, the Canadian Arctic Archipelago, the Southern Andes, High Mountain Asia, the Russian Arctic, Iceland and the Norwegian archipelago Svalbard. The five Arctic regions accounted for the greatest share of ice loss.

NASA’s New Horizons Spacecraft data reveals Critical Information about Planetary Formation

 

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Data from NASA’s New Horizons mission are providing new insights into how planets and planetesimals – the building blocks of the planets – were formed. 

The New Horizons spacecraft flew past the ancient Kuiper Belt object Arrokoth (2014 MU69) on January 1st, 2019, providing humankind’s first close-up look at one of the icy remnants of solar system formation in the vast region beyond the orbit of Neptune.

The uniform color and composition of Arrokoth’s surface shows the Kuiper Belt object formed from a small, uniform, cloud of material in the solar nebula, rather than a mishmash of matter from more separated parts of the nebula. The former supports the idea that Arrokoth formed in a local collapse of a cloud in the solar nebula.

NASA’s Lucy Mission discovers asteroid Eurybates has a Satellite

 

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA’s Lucy mission team is seeing double after discovering that Eurybates, the asteroid the spacecraft has targeted for flyby in 2027, has a small satellite. This “bonus” science exploration opportunity for the project was discovered using images taken by the Hubble Space Telescope’s Wide Field Camera 3 in September 2018, December 2019, and January 2020.

Launching in October 2021, Lucy will be the first space mission to study the Trojan asteroids, a population of small bodies orbiting the Sun “leading” and “trailing” Jupiter, at the same distance from the Sun as the gas giant.

Customs House Museum and Cultural Center to feature Belgin Yucelen’s Sculptural Garments

 

Customs House Museum & Cultural CenterClarksville, TN – Through January 12th, 2020, the Jostens Gallery of the Customs House Museum & Cultural Center is featuring the sculptural dresses of Belgin Yucelen.

The exhibition, titled Semblance, consists of garments portraying a past culture’s sophistication. Yucelen creates her dresses similar to the Turkish styles of the 17th through 19th centuries. She used traditional techniques and materials from Turkey and other parts of Asia to add embellishments to the metal dresses.
