Check itsthemind's Instagram @Regrann from @nasagoddard -  NASA Study Hints at Possible Change in Water ‘Fingerprint’ of Comet

A trip past the sun may have selectively altered the production of one form of water in a comet – an effect not seen by astronomers before, a new NASA study suggests.

Astronomers from NASA’s Goddard Space Flight Center in Greenbelt, Maryland, observed the Oort cloud comet C/2014 Q2, also called Lovejoy, when it passed near Earth in early 2015. Through NASA’s partnership in the W. M. Keck Observatory on Mauna Kea, Hawaii, the team observed the comet at infrared wavelengths a few days after Lovejoy passed its perihelion – or closest point to the sun.

The team focused on Lovejoy’s water, simultaneously measuring the release of H2O along with production of a heavier form of water, HDO. Water molecules consist of two hydrogen atoms and one oxygen atom. A hydrogen atom has one proton, but when it also includes a neutron, that heavier hydrogen isotope is called deuterium, or the “D” in HDO. From these measurements, the researchers calculated the D-to-H ratio – a chemical fingerprint that provides clues about exactly where comets (or asteroids) formed within the cloud of material that surrounded the young sun in the early days of the solar system. Researchers also use the D-to-H value to try to understand how much of Earth’s water may have come from comets versus asteroids.

Check cirm_stemcells's Instagram A new stem cell-based bioassay could reduce animal testing in research. Scientists from the University of Bern in Switzerland have developed an electronic bioassay that can record the electrical activity of stem cell-derived neurons grown in a Petri dish. They are treating these neurons with small quantities of Botox to model treatments for disorders like migraines and muscle spasms. Botox is a neurotoxin that blocks signals between nerves and muscle and when used on animals like mice, causes paralysis and sometimes suffocation. This alternative bioassay will allow scientists to test Botox and other chemicals on cells instead of animals. The system could be used for high throughput drug screening to find drugs that are beneficial to nerve signaling. You can read more about this study on our Stem Cellar blog (link in bio and here http://bit.ly/2meexLw). 1461048557830004234_2159714641

In summary, Astronaut Bluford became the first African-American in space when he flew on the space shuttle Challenger in 1983. He was a former Air Force fighter pilot who flew 144 combat missions in the Vietnam War in 1966-67. #history #SpaceAge #AmericanHistory #family #astronaut #science #BlackHistory365 #airforce #pilot #SpaceShip #funfact 1461048603874302585_405138441

Check 99217's Instagram If planets could talk, a newly-discovered asteroid belt orbiting a double sun about 1,000 light years from Earth may contain one that might send Luke Skywalker this message, since it’s the first evidence of solid planetary material ever discovered in a binary system.
The discovery is interesting for a number of non-Star Wars reasons, according to the announcement published in Nature Astronomy. The biggest, says study lead author Dr. Jay Farihi of the University College London Physics & Astronomy department, was finding out that the white dwarf the team had been studying actually a brown dwarf partner. The binary system – now named SDSS 1557 – is a white dwarf about the mass of our Sun orbited by a large brown dwarf about 60 times more massive than Jupiter. Until now, the exoplanets discovered orbiting binary systems have been gas giants like Jupiter. The asteroid belt in SDSS 1557 means a solid planet could have formed there. The white dwarf is an old star, which implies the asteroids are also old and the belt is stable. The researchers found that the rocks have a high metal content, predominantly silicon and magnesium, and there are a lot of them. Their composition was determined by analyzing the light created by some loose debris as it hit the white dwarf, and the combined mass was about the size of a 4 km asteroid.
Why have no solid planets been found orbiting binary stars before? Dr. Farihi explains:
Building rocky planets around two suns is a challenge because the gravity of both stars can push and pull tremendously, preventing bits of rock and dust from sticking together and growing into full-fledged planets. With the discovery of asteroid debris in the SDSS 1557 system, we see clear signatures of rocky planet assembly via large asteroids that formed, helping us understand how rocky exoplanets are made in double star systems. 1461047778653531544_2523622912

Check ariannesjoy's Instagram The results from our BORAX CRYSTAL experiment!!😮😎💎🔎👌
.
How-to:
1. Carefully add boiling water to a clear glass jar or cup almost full.
2. Add three spoons of borax and stir
(You want to see some borax still sitting on the bottom.)
3. Shape a pipe fitter into a fun shape...be sure it will still fit into the jar.
4. Tie string or yarn around it.
5. Attach other side of string to a popsicle stick or skewer.
6. Be sure the pipe cleaner doesn't touch the bottom, as it will get stuck there.
7. Wait 5 hours or overnight for results!!
