So what would happen if our solar system, in its orbit around the Milky Way, passed through a gas cloud several light years in diameter? Well the results are pretty shocking.
The first thing that would happen is that the gas would block alot of the Sun's light and decrease its relative luminosity by around 10%. This would make the Earth's average temperature go from 15 degrees Celsius to approximately​ 5 degrees. The gas might also bond with the current gasses making up our Atmosphere, thus changing it completely. The result might be a complete eradication of our ozone layer, making the Sun's UV light far more harmful, or a change in the air we breathe, making us suffocate. But our magnetic field could protect us from alot of the gas that would ruin our Atmosphere, but I'm not an expert in physics so I don't know.

Conclusion: If our solar system passed through a gas cloud, there would most likely be an extinction event.

This year's flu was no bueno. Fortunately, I had enough energy to head to @spacecenterhou for the @NASA #spacebowl . And of course, I wore the jumpsuit. When I walked in, a sweet little Texas lady smiled at me and said, "Looks like you're ready for SPAYCE!" 👩🏼‍🚀

At the Kennedy Space Center, touring the complex for tomorrow's #NOAA #GOESR launch onboard ULA's Atlas V 541 #NASASocial

Perfect fit! Trying on a spacesuit helmet at the NBL where astronauts train underwater for spacewalks. #NASASocial #SpaceBowl #JohnsonSpaceCenter

Gives whole new meaning to ‘Go Long’! May the spectacular plays of Super Bowl be as spectacular as what humans are doing daily aboard the @ISS! The #SB51 #NASASocial is Feb 1.

MOST RECENT

In the late 1970s, NASA climate scientists discovered growing holes in the ozone layer and linked them to the widespread use of CFCs. Thanks to their advocacy, CFCs were banned in 1987. The holes in ozone layer are closing and should be fully repaired by the end of the 21st century. Had CFC use continued, it was on track to destroy the ozone layer by 2030 at which point, we would not have been able to grow plants outside. Thanks to NASA scientists we have nifty things like Velcro and microprocessors, and also, a chance of grandchildren.
Thanks again to NASA for letting The World's Most Fashionable Paperdoll visit last fall for the Osiris Rex launch! It was phenomenal to sit and listen to the scientists who work there.
We have since adopted the NASA protocol "avoid known risks" as a personal motto. (Especially for former crushes) #nasasocial #nasa #science #climatechange #drawntoadventure #illo #instaart

Nebulas are clouds of interstellar gas and dust that contains hydrogen, helium, and other ionized particles. ✨💨
When a star reaches the end of its life, it undergoes a huge explosion and its remnants can slowly form expanding clouds of dust. These clouds can even cycle around to form newborn stars! 🌟There are many types of nebulas (pictured in order): •Reflection nebula: reflects light from nearby stars and usually appear blue (NGC 7023) •Emission nebula: absorbs light from nearby stars and re-emits it at a lower energy level. Hydrogen is a dominant element in these, causing them to appear red. New stars are usually born in this type of nebula. (The Orion Nebula) •Dark nebula: has clouds so dense they block whatever light behind it. (The Horsehead Nebula) •Planetary nebula: formed from gas emitted from a small star (like our sun) reaching the end of its life (The Ring Nebula)
What's your favorite type?? 🌟 📸 credit: Hubble Space Telescope

Many of you have asked what do I do at NASA? Well, I am a Mechanical Engineer working on Spacecraft structures and materials. Here I am standing in front of the Orion Spacecraft, a capsule I am working on to safely transport Astronauts to Mars and other deep space missions. 🚀 Learn more, link in ➩ my bio.

In the next post, I will hopefully discuss the possibility of our Solar Systen passing through one of the gas clouds on its orbit around the Milky Way.

A friend's blessing is also your blessing. This week was chock full of sunshine. Congratulations to the amazing @insta_barb7 on her #PRNews win earlier this week in Washington D.C. Thrilled that we could celebrate together and ever so grateful that a little ok' space shuttle and @NASA brought us into each others' lives. 🏆☀️🚀✨

39.5 ~ light years that is
The distance to the 7 planet system orbiting the dwarf star Trappist 1 in the constellation Aquarius. -------------------------------
The three rocky planets in the Trappist 1 "goldilocks zone" are much closer to each other than the 3 rocky planets in our own systems habitable zone. This gets scientists thinking about panspermia. The transfer of life between planetary bodies by meteorites. Problems with the panspermia hypothesis include the length of time organisms would have to survive, the heat of impact and the preponderance of UV radiation in interplanetary space. I would posit little hearty buggers like tardigrades (water bears) might make the grade as interplanetary hitchhikers. ------------------------------
A new paper using a simple model suggests that panspermia is several orders of magnitude more likely in the Trappist 1 system than in our own solar system. One of the paper"s authors Manasvi Lingham suggests " If the same biosignature gasses are detected on planets in a single system, or if the spectral feature of vegetation occurs at the same wavelength, this could be the 'smoking gun'& #34;

This galaxy has a far more exciting and futuristic classification than most — it hosts a megamaser. Megamasers are intensely bright, around 100 million times brighter than the masers found in galaxies like the Milky Way. The entire galaxy essentially acts as an astronomical laser that beams out microwave emission rather than visible light (hence the ‘m’ replacing the ‘l’). A megamaser is a process where some components within a galaxy (like gas clouds) are in the right stimulated physical condition to radiate intense energy (in this case, microwaves). This megamaser galaxy is named IRAS 16399-0937 and is located over 370 million light-years from Earth. This NASA/ESA Hubble Space Telescope image belies the galaxy’s energetic nature, instead painting it as a beautiful and serene cosmic rosebud. The image comprises observations captured across various wavelengths by two of Hubble’s instruments: the Advanced Camera for Surveys (ACS), and the Near Infrared Camera and Multi-Object Spectrometer (NICMOS). NICMOS’s superb sensitivity, resolution, and field of view gave astronomers the unique opportunity to observe the structure of IRAS 16399-0937 in detail. They found it hosts a double nucleus — the galaxy’s core is thought to be formed of two separate cores in the process of merging. The two components, named IRAS 16399N and IRAS 16399S for the northern and southern parts respectively, sit over 11,000 light-years apart. However, they are both buried deep within the same swirl of cosmic gas and dust and are interacting, giving the galaxy its peculiar structure.

The nuclei are very different. IRAS 16399S appears to be a starburst region, where new stars are forming at an incredible rate. IRAS 16399N, however, is something known as a LINER nucleus (Low Ionization Nuclear Emission Region), which is a region whose emission mostly stems from weakly-ionized or neutral atoms of particular gases. The northern nucleus also hosts a black hole with some 100 million times the mass of the sun!
