Alok’s comments from the Astronomy and Space exploration group.

Arcturus is a beautiful , and it is the third Brightest star in the sky .

Mine is VEGA , from Lyra constellation. i have been staring at that star since childhood . It is the first star i ever started to wonder about . And this star introduced me to the world of astronomy , and it is this star that made me wonder about how stars work and it is this star that changed my complete view of nature for ever

Hai guys ..I have asked you one simple question . Which is your favorite STAR in the sky . And why ?, what does it mean to you ?

Yes . But I am hardly hoping to see it in my lifetime

true!

And that answers another Big Question "Are we alone?" and later we can say " "no dude , they watching from above" ...hahaha.

Thats amazing though . Just think about it . if we decode that information we can use it to arrange matter with reference to the information . we can create matter back that was destroyed by the Black hole long long back .

I needed a help from you .....The magazine you are reading ANALOG SCIENCE FICTION and FACT . Is that series good , can i please know your review about it ? ... I was thinking of buying those Magazines

Hai Mr.Jon . Welcome to our small group . We are very glad to Have you

Guys the thing is , Comets and Meteors are mostly common , This very case made it to the Internet community because , Its unusual . Its shape , its size , color , and fact that it has an interstellar origin is an interesting factor . And speaking of interstellar origin , we may point out at the Movie Contact , if it was an alien artifact or anything belonging to life , But it isn't . Its just an Unusual Interstellar Object

Thanks ..thats a amazing story . Now there will be a lot of Alien kind of discussion about its origins on the Internet

Its Simple , just like conservation of mass , energy ....there is something called Conservation of Information saying, Information
can neither be created nor destroyed. And Starman ., thats Amazing Question , i had this Doubt long ago , what i know is (i may be wrong) .....the information of the arrangement of atoms of any matter thats gone into the black hole , is liberated in an encrypted way in the form of Radiation , OR maybe there's something on the other side of the Black Hole , Maybe Antimatter universe or something , we still dont know

Yes but i wouldnt use the word CONVERT , it doesnt convert anything into anything .....its actually , Black hole's gravitational pull is soooo powerful , it rips of out structure ...Clearly our body or any matter near a black hole continues to stretch and rip off , and this process continues one and one , until, only thing that remains are our atoms .

Imagine a trip into a black hole. This tantalizing thought has excited much creative speculation.There are two ways to consider the issue. One is to "watch" someone or something -- say a small robot spacecraft -- fall into the black hole. The odd thing is it never seems to get there. The closer it approaches the hole's event horizon, the slower it seems to travel. But for the crew inside, there would be no warning of its impending doom.

Let's assume that you start outside the event horizon of the black hole. As you look toward it, you see a circle of perfect darkness. Around the black hole, you see the familiar stars of the night sky. But their pattern is strangely distorted, as the light from distant stars gets bent by the black hole's gravity.

As you fall toward the black hole, you move faster and faster, accelerated by its gravity. Your feet feel a stronger gravitational pull than your head, because they are closer to the black hole. As a result, your body is stretched apart. For small black holes, this stretching is so strong that your body is completely torn apart before you reach the event horizon.

If you fall into a supermassive black hole, your body remains intact, even as you cross the event horizon. But soon thereafter you reach the central singularity, where you are squashed into a single point of infinite density. You have become one with the black hole. Unfortunately, you are unable to write home about the experience.

What actually is singularity ?
A singularity means a point where some property is infinite. For example, at the center of a black hole, according to classical theory, the density is infinite (because a finite mass is compressed to a zero volume). Hence it is a singularity.


What are your thoughts Guys ? Do you still think going into a black hole is exciting? ... Tell me your thoughts

Hai guys , Today , Cassini spacecraft which had been orbiting Saturn for the last Decade has successfully ended its Mission by plunging into Saturn . After a great success of its missions sending us back data and helping us study the planet in a great detail , Agencies decided to end its mission after two decades . check out this site for more information https://www.cnet.com/news/nasa-cassin...

Great to hear that ...Welcome to the group friend .......

Yes ......Searching For the reality of nature is a kind of "Mass Quest" and when i say mass , i mean entire Humanity through all its generations .....And surely it should happen in a certain chain of events ...like if Newton Hadn't discovered Gravity , maybe Relativity might not have been proposed......And speaking of Advancement , Sometime Late next year , we might have the Giant JAMES WEBB SPACE TELESCOPE orbiting at an extreme distance around the earth , Just imagine , a telescope , size of a school bus opened hundreds of secrets about our universe and unlocked secrets of formation of Stars (our true ancestors) ......What might the Giant Telescope shielded with something the size of a Tennis court could do .......oo i cant wait to see those first astonishing images JWST sends us .......

I Completely agree . Its all about the patterns ...But i see that these patterns are not uniform though , i mean , for example Quantum Mechanics shows an entirely Different set of rules and patterns and when we come to the next level , there are mostly these biological stuff , Speaking of which , Fabbonacci sequence comes in action and the next level , its the world of Newtonian Mechanics ...and going further , there wierd stuff , these stars , pulsars , quasars need some different set of Math , and speaking of wierd things , Black holes , Dark matter , Dark energy , Anti matter and Light itself ....Show entirely Different patterns and behaviour .......... ......Thinking of all these stuff around us , leaves less hope in me of Humanity Finding an Ultimate Theory ...or an Ultimate Godly Mathematical Equation that unifies everything ................But it remains to be seen

1. The Apollo's Saturn rockets were packed with enough fuel to throw 100-pound shrapnel three miles, and NASA couldn't rule out the possibility that they might explode on takeoff. NASA seated its VIP spectators three and a half miles from the launchpad.

2. The Apollo computers had less processing power than a cellphone.

3. Drinking water was a fuel-cell by-product, but Apollo 11's hydrogen-gas filters didn't work, making every drink bubbly. Urinating and defecating in zero gravity, meanwhile, had not been figured out; the latter was so troublesome that at least one astronaut spent his entire mission on an anti-diarrhea drug to avoid it.

4. When Apollo 11's lunar lander, the Eagle, separated from the orbiter, the cabin wasn't fully depressurized, resulting in a burst of gas equivalent to popping a champagne cork. It threw the module's landing four miles off-target.

5. Pilot Neil Armstrong nearly ran out of fuel landing the Eagle, and many at mission control worried he might crash. Apollo engineer Milton Silveira, however, was relieved: His tests had shown that there was a small chance the exhaust could shoot back into the rocket as it landed and ignite the remaining propellant.

6. The "one small step for man" wasn't actually that small. Armstrong set the ship down so gently that its shock absorbers didn't compress. He had to hop 3.5 feet from the Eagle's ladder to the surface.

7. When Buzz Aldrin joined Armstrong on the surface, he had to make sure not to lock the Eagle's door because there was no outer handle.

8. The toughest moonwalk task? Planting the flag. NASA's studies suggested that the lunar soil was soft, but Armstrong and Aldrin found the surface to be a thin wisp of dust over hard rock. They managed to drive the flagpole a few inches into the ground and film it for broadcast, and then took care not to accidentally knock it over.

9. The flag was made by Sears, but NASA refused to acknowledge this because they didn't want "another Tang."

10. The inner bladder of the space suits—the airtight liner that keeps the astronaut's body under Earth-like pressure—and the ship's computer's ROM chips were handmade by teams of "little old ladies."

11. President Nixon was prepared for the worst, as was his speechwriter William Safire. Safire put together a tribute to the Apollo 11 astronauts just in case they never made it home. "In ancient days, men looked at stars and saw their heroes in the constellations," the president would have read in one of the speech’s poignant lines. "In modern times, we do much the same, but our heroes are epic men of flesh and blood."

12. The original footage from the lunar camera is gone. First noticed missing in 2006, the tapes were likely erased and reused to record data beaming back from one of several satellites launched in the 1980s. This lost footage, which was much clearer that what viewers saw on television, survives only in the broadcast formats.

12.According to the astronauts who landed there, the moon has a smell. After tracking moon dust back into the lunar module and removing their helmets, astronauts Neil Armstrong and Buzz Aldrin thought the lunar materials smelled of "wet ashes in a fireplace" and "gunpowder," respectively. But back here on Earth, our oxygen-rich atmosphere renders the moon dust odor-free.

That's a striking point ......
