NASA’s Hubble Spots Possible Water Plumes Erupting on Jupiter's Moon Europa

Astronomers working with the NASA Hubble Space Telescope have captured images of what might be water vapor plumes erupting from the surface of Jupiter's moon Europa. “This finding bolsters other Hubble observations suggesting the icy moon erupts with high altitude water vapor plumes,” reports NASA. “ The observation increases the possibility that missions to Europa may be able to sample Europa’s ocean without having to drill through miles of ice.”

Grace Potter rocks out with NASA in new video on the women of America's space program

Share this inspiring video with every kid or teen you know who dreams of space. John Streeter of NASA Television has sent us some wonderful NASA TV videos over the years. I love this new one with Vermont-born rock and roll star Grace Potter, about some of the amazing women in the history of the American space program. I hope it inspires a little girl out there to become an astronaut.

NASA’s Curiosity Mars Rover Views Spectacular Layered Rock Formations of “Murray Buttes”

Reports NASA today, “The layered geologic past of Mars is revealed in stunning detail in new color images returned by NASA's Curiosity Mars rover, which is currently exploring the 'Murray Buttes' region of lower Mount Sharp. The new images arguably rival photos taken in U.S. National Parks.”

NASA launches OSIRIS-REx asteroid sample mission now speeding toward Bennu rendezvous

NASA reports that its first ever asteroid sampling mission launched into space at 7:05 p.m. EDT Thursday from Cape Canaveral Air Force Station in Florida, “beginning a journey that could revolutionize our understanding of the early solar system.”

OSIRIS-REx, which is short for Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer, is headed to the near-Earth asteroid called Bennu.

The probe's job: Touch the asteroid (after asking consent first, and with a platonic vibe) so we can bring a small sample back to Earth for study. If all goes as planned after today's launch, the spacecraft will reach Bennu in 2018 and return a sample to Earth in 2023.

Hurricane Hermine to Hit Florida's Gulf Coast with 'Life Threatening' Force

Tropical Storm Hermine officially reached hurricane status on Thursday, Sept. 1, 2016, reported NASA and NOAA's National Hurricane Center earlier today. When it makes landfall, it will be the first hurricane to hit Florida since Wilma in 2005. Hermine will probably touch down along the state's eastern Panhandle in the wee hours of Friday morning, and NOAA predicts that its force and the associated water surges will be “life-threatening.”

NASA’s High Dynamic Range Stereo X camera captures rocket test in breathtaking detail

This is cool as hell. “While thousands turned out to watch NASA’s Space Launch System (SLS) recently complete a full-scale test of its booster, few were aware of the other major test occurring simultaneously.” NASA’s High Dynamic Range Stereo X (HiDyRS-X) camera project captured the test like we've never seen before, and recorded propulsion video data in unprecedented detail.

Why did Iran's Lake Urmia just change from bright green to blood red?

Between April and July, Iran's salty Lake Urmia changed from a bright green color to a blood red. NASA's Aqua satellite captured the image above and reported on the science behind the strange transformation. According to NASA, the periodic color change is caused by micro algae producing carotenoids that help with photosynthesis and act as antioxidants and Halobacteriaceae, a bacteria in very salty water that releases "a red pigment called bacteriorhodopsin that absorbs light and converts it into energy for the bacteria." From NASA:

The color changes have become common in the spring and early summer due to seasonal precipitation and climate patterns. Spring is the wettest season in northwestern Iran, with rainfall usually peaking in April. Snow on nearby mountains within the watershed also melts in the spring. The combination of rain and snowmelt sends a surge of fresh water into Lake Urmia in April and May. By July, the influx of fresh water has tapered off and lake levels begin to drop.

The fresh water in the spring drives salinity levels down, but the lake generally becomes saltier as summer heat and dryness take hold. That’s when the microorganisms show their colors, too. Careful sampling of the water would be required to determine which organisms transformed the lake in 2016, but scientists say there are likely two main groups of organisms involved: a family of algae called Dunaliella and an archaic family of bacteria known as Halobacteriaceae.

While Lake Urmia has shifted from green to red and back several times in recent years, trends suggest that a red Urmia could become increasingly common.
