Westerlund 1🌟

✨Westerlund 1 is a compact young super star cluster in the Milky Way galaxy, about 2.6 kpc (8480 ly) away from Earth.

It is one of the most massive young star clusters in the Milky Way, and was discovered by Bengt westerlund in 1961 but remained largely unstudied for many years due to high interstellar absorption in its direction. In the future, it will probably evolve into a globular cluster✨

Can we see the flag on the Moon with a telescope👀?

✨Yes, the flag is still on the moon, but you can't see it using a telescope. I found some statistics on the size of lunar equipment in a Press Kit for the Apollo 16 mission. The flag is 125 cm (4 feet) long, and you would need an optical wavelength telescope around 200 meters (~650 feet) in diameter to see it. The largest optical wavelength telescope that we have now is the Keck Telescope in Hawaii which is 10 meters in diameter. The Hubble Space Telescope is only 2.4 meters in diameter - much too small✨!

✨The DNA sequence of Stephen Hawking is stored on a hard disk, called the immortality Drive, onboard the ISS. He was among a select group of human to have their DNA immortalized✨

Happy Birthday Stephen Hawking🥳!

#OnThisDay in 1942 British cosmologist Stephen William Hawking was born.
🔮Stephen Hawking was regarded as one of the most brilliant theoretical physicists in history. His work on the origins and structure of the universe, from the Big Bang to black holes, revolutionized the field, while his best-selling books have appealed to readers who may not have Hawking's scientific background.

✨Active galaxy NGC 1275 lies at the heart of the Perseus Galaxy Cluster, it has huge filaments of gas that extend out from the core. They look like the tentacles of an immense galactic octopus and are 20,000 light years long, and just 200 light years wide. They are held in place by powerful magnetic fields from the massive central black hole✨

​​✨What would happen if a nuclear bomb was detonated in space?

💥When a nuclear bomb explodes on Earth, the huge release of radiation triggers the rapid expansion of air around it, causing the intense blast wave that wreaks so much destruction.

In the vacuum of space, the lack of air means the principal destructive effects come not from the blast, but instead from the particles and radiation pouring out of the bomb, which dump their energy as heat on striking the target✨

Where does space actually start?

✨The Kármán line, an altitude of 100 km (62 mi) above sea level, is conventionally used as the start of outer space in space treaties and for aerospace records keeping. The framework for international space law was established by the Outer Space Treaty, which entered into force on 10 October 1967✨

✨Jupiter's Great Red spot is so loud, it's acoustic sound waves heat up the surrounding atmosphere to almost 2400 degrees Fahrenheit✨

✨Definition: Radio astronomy is a subfield of astronomy that studies celestial objects at radio frequencies. Subsequent observations have known a variety of various sources of radio waves. These embrace stars and galaxies, likewise as entirely new categories of objects like radio galaxies, quasars, and pulsars✨

Quantum Teleportation💥

✨Quantum Teleportation is a process in which quantum information can be transmitted from one location to another with the help of a shared quantum entanglement between the sending and receiving locations.

• Quantum teleportation is not a form of transportation, but of communication, it provides a way of transferring a qubit (a unit of quantum information) from one location to another.
The latest reported record distance for quantum teleportation is 1400 km by the Chinese researchers using Micius satellite for space-based quantum teleportation.
Quantum information can be neither copied, not destroyed✨

✨If Jupiter were 80 times more massive, it would turn into a star✨

✨The Oh-My-God particle was an ultra-high-energy cosmic ray that was detected on 15 October 1991 by the University of Utah.
--It was traveling so absurdly fast that time dilation dictates that it would have experienced only 16 days of time since the beginning of the universe✨

✨The ocean on Jupiter is larger than any other in the solar system but unlike Earth's oceans, It's made not of water but of metallic hydrogen. The ocean’s depth is a mind-blowing 25,000 miles, it's almost the same as the distance around the Earth✨

What Exactly Is a Black Hole Event Horizon (and What Happens There)? | Space

#EventHorizon
👉 @AstroMechanics

What is Event Horizon?

✨A black hole's “surface,” called its event horizon, defines the boundary where the velocity needed to escape exceeds the speed of light, which is the speed limit of the cosmos. Matter and radiation fall in, but they can't get out.
💫According to Einstein's theory of special relativity, nothing can travel faster through space than the speed of light✨

What is the speed of dark?

✨Most of us already know that darkness is the absence of light, and that light travels at the fastest speed possible for a physical object. So, what does this mean? In short, it means that, the moment that light leaves, darkness returns. In this respect, darkness has the same speed as light✨

💥The Bubble Nebula

✨Also called NGC 7635. The nebula is 7,100 light-years away, in the direction of the Cassiopeia Constellation.

It is really a bubble that has been inflated by a massive star with its stellar wind. The star has a mass 45 times that of the sun and a luminosity hundreds of thousands of times greater✨

Why do astronauts not fly to the dark side of the Moon?

✨The point is that there is no radio communication with Earth on the other side of the Moon.
--One solution to this problem is to use a constellation of satellites to send a signal, though this approach is expensive and difficult.

‼Sending people to the Moon without constant communication is an unreasonable risk✨

The Solar System has its own tail

✨It looks most like the tail of a comet. We call it the heliotail. Nothing was known about it for the simple reason that the tail consists of particles invisible to traditional instruments.

✔️ The heliotel stretches 13 billion kilometers from the edge of the solar system✨
