NASA SEEKS NEXT FLIGHT DIRECTORS FOR HUMAN SPACEFLIGHT MISSION

✨NASA is looking for leaders for one of the best jobs on Earth for human spaceflight – including missions to the Moon – the position of flight director in mission control at the agency’s Johnson Space Center in Houston.

🔮Those chosen as NASA flight directors will lead human spaceflight missions to the International space station and upcoming Artemis missions to the Moon, and, eventually, the first human missions to Mars.
✍Applications for new flight directors is open now through Thursday, Dec. 16. U.S. citizens can apply at: https://go.nasa.gov/3ltYoPO✨

✨Sedna is a dwarf planet with a highly elliptical orbit around sun. It is about three times as far Neptune from the Sun. Scientists hypothesize that it was placed in its orbit by a passing star, as there is no other explanation for its unusual orbit around the Sun✨

💥Did you know?

✨It's by pure coincidence that we exist on a planet and in a time when our star(Sun) is covered exactly during a total eclipse. No other known planet has total eclipse and at some point in the planet future they won't occur on Earth either✨

The Falcon Lake incident (1967)

✨On day in Manitoba, Canada, a person named Stefan Michalak apparently saw an unidentified alien craft land nearby when he was out prospecting for gold and silver.
👀Stefan approached the craft and apparently heard human-like voices muffled by the engines. He went close enough to poke his head inside the craft and saw "a maze of lights" within.
🛸He was then startled when the craft took off and injured by a beam of heat that shot from the ship. The heat set fire to his clothes and severely burnt his chest. Doctors and authorities could not explain his injuries and this added credence to his story which he repeated in interviews until his death in 1999✨.

What gives the planet its red color?

✨The answer can be found it is regolith. The regolith is the blanket of loose rocks and dust that covers a celestial body. The regolith of Mars is found to have minerals rich in iron, which gives it its typical red color✨

☄Largest Asteroid

✨The largest asteroid in our solar system is a mammoth piece of space rock named Ceres, which is sometimes known as a drawf planet. It is almost 600 miles in diameter. It's by far the largest Asteroid Belt between Mars and Jupiter and accounts for a whole third of the belt's mass✨.

🌟Did you know?

✨The North star is 4000 times brighter than our sun. The light we see when we look at the north star was generated in the year 1587, and it has been traveling through space for 434 years to reach us✨

👆In this image, the NASA/ESA Hubble Space Telescope captures a side-on view of NGC 3568, a barred spiral galaxy roughly 57 million light-years from the Milky Way in the constellation Centaurus. In 2014 the light from a supernova explosion in NGC 3568 reached Earth a sudden flare of light caused by the titanic explosion accompanying the death of a massive star✨

There are more trees on Earth than stars in the Milky way🌳⭐

✨There are about three trillion trees on Planet Earth, and between 100-400 billion stars, approximately, in the galaxy.

The Last Full moon of the Year🌚

✨The last full moon of the year rises on Dec. 18, according to AccuWeather. Bundle up to enjoy the last full moon of the year. The last full moon of 2021 will reach peak illumination on Saturday, December 18, at 11:32 p.m. ET, according to NASA, but you can trace its path across the sky starting at just before sunset✨.

The Moon has no atmosphere🌕

✨This means that the surface of the Moon is unprotected from cosmic rays, meteorites and solar winds, and has huge temperature variations. The lack of atmosphere means no sound can be heard on the Moon, and the sky always appears black✨

✨Quantum tunnelling or tunneling (US) is the Quantum mechanical phenomenon where a Wavefunction can propagate through a potential barrier.

🌟The transmission through the barrier can be finite and depends exponentially on the barrier height and barrier width. The wavefunction may disappear on one side and reappear on the other side. The wavefunction and its first derivative are continuous. In steady-state, the probability flux in the forward direction is spatially uniform. No particle or wave is lost. Tunneling occurs with barriers of thickness around 1–3 nm and smaller✨

💥Supernovas are brighter than a galaxy. 

✨For a short period of time, a single supernova can easily outshine an entire galaxy of stars, releasing as much energy in a single burst as our Sun will in its entire, 10 billion-year lifespan.
☄Universe's most luminous supernova was 50 times brighter than the Milky Way.

What's the closest active galaxy to planet Earth?

✨That would be Centaurus A, only 11 million light-years distant. Spanning over 60,000 light-years, the peculiar elliptical galaxy is also known as NGC 5128. Forged in a collision of two otherwise normal galaxies, Centaurus A's fantastic jumble of young blue star clusters, pinkish star forming regions, and imposing dark dust lanes are seen here in remarkable detail. The colorful galaxy portrait is a composite of image data from space- and ground-based telescopes large and small. Near the galaxy's center, left over cosmic debris is steadily being consumed by a central black hole with a billion times the mass of the Sun✨

How were the first Galaxies formed💫?

✨13.8 billion years ago, after the Big Bang gas and dust particles spread all over the Universe. Two of the most abundant constituents of our Universe at that time were Hydrogen and Dark Matter. Researchers haven't found Dark Matter yet, but assuming that it had a great role for building our Universe. Dark Matter keeps different objects together due to it's gravitational effect. Dust particles after being gravitationally collapsed and by the process of Nuclear Fusion formed stars. Due to the gravitational effect of Dark Matter, stars formed were attracted to each other. Those stars who grew old, after Supernova explotion formed Black holes. Dust and gas around the Black hole present started revolving it and formed a disk. The formations took place were making a scenario known as Bottom up scenario, those scenarios we know today for the formation of Galaxies✨
