You’ve seen things floating in space, but why does that happen and how does it affect science being conducted aboard the International Space Station?
Sure, floating looks like fun, but it could also unlock new scientific discoveries!
Microgravity makes the International Space Station the perfect place to perform research that is changing the lives of people on Earth, and preparing us to go deeper into space. This season on our series NASA Explorers, we are following science into low-Earth orbit and seeing what it takes to do research aboard the space station.
Follow NASA Explorers on Facebook to catch new episodes of season 4 every Wednesday. https://www.facebook.com/NASAExplorersSeries/
International Astronomy Day 2020 is celebrated on May 2. Take some time away from all the current distractions and look up at the amazing stars in the sky. International Astronomy Day is celebrated twice a year one in autumn and another in spring. The world will celebrate the next Astronomy Day on September 26. ---TheWorldNeedsAmazing--- Camera : Nikon Aperture : f/4 ISO. : 1600 . . . . . . . . . . . . #internationalastronomyday #astronomy #scicomm #astronomyphotography #astronomyday #astronomypictureoftheday #yourshotphotographer #stargazing #nightshooters #nightskyphotography #mountainlife #travellerlife #travelling #traveller_stories #travels #travellersdiary #traveller_india #photoeveryday #photoshot #shots #image #click #mountaineering #universe #scicommindia #graphicdesign #travelphotography #nikonphotography #nikon #nikonshot https://www.instagram.com/p/B_r2FS_j8Ad/?igshid=1kogdhu4nars4
Today in film industry another unfortunate demise! The Most Romantic, Versatile, Legendary actor Rishi Kapoor Sir, it sad that he is no more. He surely had an iconic one of my favourite. I enjoyed his many films, sang your romantic songs sir and immersed myself in many of your songs because there was a different kind of addiction in your songs, I really enjoyed your songs. The very popular, savoury, a very happy kind of person who used to awaken the hearts of love in the hearts of people with his romantic films, the craze of his films kept the hearts of the people. Our heartfelt condolence goes out to his family, friends and fans. Rishi Ji is considered as the Original Prince of Romance.🙏 #rishikapoor #filmisnotdead (at Aligarh) https://www.instagram.com/p/B_msrGsj9TZ/?igshid=7nswnym8h0s6

Climate change
Are the rumors about the ozone layer being totally fixed true ? If yes , is it susceptible of being opened again ans if no, is it suspecte
hello Friendss how r u???
International Asteroid Day aims to raise public awareness about the asteroid impact hazard and to inform the public about the crisis communication actions to be taken at the global level in case of a credible near-Earth object threat. . . . . . . #asteroid #universe #space #spacetime #astronomy #astronomer #spacestation #spacetravel #sunrise #satellite https://www.instagram.com/p/CCDuhL2DN0Z/?igshid=5vxzze8zzajg

It's a great thing.....
New Science from our Mission to Touch the Sun
In August 2018, our Parker Solar Probe mission launched to space, soon becoming the closest-ever spacecraft from the Sun. Now, scientists have announced their first discoveries from this exploration of our star!
The Sun may look calm to us here on Earth, but it’s an active star, unleashing powerful bursts of light, deluges of particles moving near the speed of light and billion-ton clouds of magnetized material. All of this activity can affect our technology here on Earth and in space.
Parker Solar Probe’s main science goals are to understand the physics that drive this activity — and its up-close look has given us a brand-new perspective. Here are a few highlights from what we’ve learned so far.
1. Surprising events in the solar wind
The Sun releases a continual outflow of magnetized material called the solar wind, which shapes space weather near Earth. Observed near Earth, the solar wind is a relatively uniform flow of plasma, with occasional turbulent tumbles. Closer to the solar wind’s source, Parker Solar Probe saw a much different picture: a complicated, active system.
One type of event in particular drew the eye of the science teams: flips in the direction of the magnetic field, which flows out from the Sun, embedded in the solar wind. These reversals — dubbed “switchbacks” — last anywhere from a few seconds to several minutes as they flow over Parker Solar Probe. During a switchback, the magnetic field whips back on itself until it is pointed almost directly back at the Sun.
The exact source of the switchbacks isn’t yet understood, but Parker Solar Probe’s measurements have allowed scientists to narrow down the possibilities — and observations from the mission’s 21 remaining solar flybys should help scientists better understand these events.
2. Seeing tiny particle events
The Sun can accelerate tiny electrons and ions into storms of energetic particles that rocket through the solar system at nearly the speed of light. These particles carry a lot of energy, so they can damage spacecraft electronics and even endanger astronauts, especially those in deep space, outside the protection of Earth’s magnetic field — and the short warning time for such particles makes them difficult to avoid.
Energetic particles from the Sun impact a detector on ESA & NASA’s SOHO satellite.
Parker Solar Probe’s energetic particle instruments have measured several never-before-seen events so small that all trace of them is lost before they reach Earth. These instruments have also measured a rare type of particle burst with a particularly high number of heavier elements — suggesting that both types of events may be more common than scientists previously thought.
3. Rotation of the solar wind
Near Earth, we see the solar wind flowing almost straight out from the Sun in all directions. But the Sun rotates as it releases the solar wind, and before it breaks free, the wind spins along in sync with the Sun’s surface. For the first time, Parker was able to observe the solar wind while it was still rotating – starting more than 20 million miles from the Sun.
The strength of the circulation was stronger than many scientists had predicted, but it also transitioned more quickly than predicted to an outward flow, which helps mask the effects of that fast rotation from the vantage point where we usually see them from, near Earth, about 93 million miles away. Understanding this transition point in the solar wind is key to helping us understand how the Sun sheds energy, with implications for the lifecycles of stars and the formation of protoplanetary disks.
4. Hints of a dust-free zone
Parker also saw the first direct evidence of dust starting to thin out near the Sun – an effect that has been theorized for nearly a century, but has been impossible to measure until now. Space is awash in dust, the cosmic crumbs of collisions that formed planets, asteroids, comets and other celestial bodies billions of years ago. Scientists have long suspected that, close to the Sun, this dust would be heated to high temperatures by powerful sunlight, turning it into a gas and creating a dust-free region around the Sun.
For the first time, Parker’s imagers saw the cosmic dust begin to thin out a little over 7 million miles from the Sun. This decrease in dust continues steadily to the current limits of Parker Solar Probe’s instruments, measurements at a little over 4 million miles from the Sun. At that rate of thinning, scientists expect to see a truly dust-free zone starting a little more than 2-3 million miles from the Sun — meaning the spacecraft could observe the dust-free zone as early as 2020, when its sixth flyby of the Sun will carry it closer to our star than ever before.
These are just a few of Parker Solar Probe’s first discoveries, and there’s plenty more science to come throughout the mission! For the latest on our Sun, follow @NASASun on Twitter and NASA Sun Science on Facebook.
