The shimmering colors visible in this NASA/ESA Hubble Space Telescope image, released 8/24/15, shows off the remarkable complexity of the PN M2-9 Twin Jet Nebula which is also known as Minkowski's Butterfly, the Wings of a Butterfly Nebula or simply Butterfly Nebula.   The luminous nebula is about 2,100 light-years away from Earth.  Unlike ordinary planetary nebulae which has one star at their center, this is a bipolar nebula which has two stars from a binary star system. (ESA/Hubble & NASA)

A bioreactor stands in the production facilities of Protein Sciences in Pearl River, New York, Tuesday on 8/18/15. Protein Sciences is among the companies working on a greater variety of vaccine options for the coming flu season.  The company’s genetically engineered vaccine called Flublok was developed for people allergic to eggs.   Those with egg allergies are unable to receive regular flu vaccines. (AP)

Mmmmm space lettuce! Expedition 44 crewmembers aboard the International Space Station sampled their harvest of a crop of "Outredgeous" red romaine lettuce on 8/10/15.  The lettuce was grown with the ISS’ veggie plant growth system that tests hardware for growing vegetables and other plants in space. (NASA)

Technicians check out the CALorimetric Electron Telescope (CALET) and Flight Crew Interface Test (FCIT).  CALET, which was sent to the International Space Station on 8/24/15 aboard a Japan Aerospace eXploration Agency (JAXA’s) resupply spacecraft.  The CALET will search for signatures of dark matter and provide the highest energy direct measurements of the cosmic ray electron spectrum. (NASA)

This is a new image, released 8/24/15, of the globular cluster NGC 1793 that was taken with the Advanced Camera for Surveys (ACS) on board the NASA/ESA Hubble Space Telescope.  One of the biggest globular clusters in the Large Magellanic Cloud this cluster, located nearly 160,000 light years from Earth, was discovered by John Herschel in 1835. (ESA/Hubble & NASA)
