What is the strangest thing in space?

What is the strangest sound in space?

Scientists have discovered a "strange and persistent" radio signal from a far-off galaxy that sounded like a heartbeat. Astronomers at the Massachusetts Institute of Technology and elsewhere detected the signal, which is classified as a fast radio burst, or FRB — but lasted much longer.

Is space completely silent?

No, there isn't sound in space.

This is because sound travels through the vibration of particles, and space is a vacuum. On Earth, sound mainly travels to your ears by way of vibrating air molecules, but in near-empty regions of space there are no (or very, very few) particles to vibrate – so no sound.

What are the weirdest things in the universe?

But the most intriguing section catalogs anomalies: strange, unexplained objects such as “puffy” planets, slow-spinning pulsars, interstellar asteroids, fast radio bursts from beyond the Milky Way, and dozens more. Astronomers say they're likely to discover natural (if bizarre) explanations for them.

What is a scary fact about space?

Black holes are obviously terrifying: These crushed remnants of a massive star that exploded as a supernova are so massive that nothing, not even light, can escape its grasp.

25 Space Facts That Will Both TERRIFY And AMAZE You

What is the darkest thing in space?

Black holes are the darkest things in our universe because they emit no light whatsoever in any wavelength.

What's the deadliest thing in the universe?

These explosions generate beams of high-energy radiation, called gamma-ray bursts (GRBs), which are considered by astronomers to be the most powerful thing in the universe. What's more, these GRBs could be killing our chances of ever discovering life on other planets.

What is the rarest space object?

Only 1-in-10,000 galaxies fall into the rarest category of all: ring galaxies. With a dense core consisting of old stars, and a circular or elliptical ring consisting of bright, blue, young stars, the first ring was only discovered in 1950: Hoag's object.

What is the craziest fact about space?

There is no atmosphere in space, which means that sound has no medium or way to travel to be heard. 2. THE HOTTEST PLANET IN OUR SOLAR SYSTEM IS 450° C. Venus is the hottest planet in the solar system and has an average surface temperature of around 450° C.

What is the coolest thing found in space?

Do we age faster in space?

Previous research has shown that spending time in space causes bone density loss, immune dysfunction, cardiovascular issues such as stiffening of arteries, and loss of skeletal muscle mass and strength in both humans and rodent models. These changes resemble aging in people age on Earth, but happen more quickly.

What does space smell like?

A succession of astronauts have described the smell as '… a rather pleasant metallic sensation ... [like] ... sweet-smelling welding fumes', 'burning metal', 'a distinct odour of ozone, an acrid smell', 'walnuts and brake pads', 'gunpowder' and even 'burnt almond cookie'.

What would happen if you scream in space?

Sound is a mecanical wave, which means that it needs substance to travel through, such as air or water. In space, there is no air, so sound has nothing to travel through. If someone were to scream in space, the sound wouldn't even leave their mouths.

What is the loudest thing in the universe?

The loudest sound in the universe definitely comes from black hole mergers. In this case the “sound” comes out in gravitational waves and not ordinary sound waves.

How loud is a black hole?

Hailey et al.) For the first time in history, earthlings can hear what a black hole sounds like: a low-pitched groaning, as if a very creaky heavy door was being opened again and again.

Why can't astronauts whistle in space?

Because there is nothing out in space (like an atmosphere), the sound waves from one astronaut's whistling can't travel over to the other astronaut's ears. That's why the astronauts use radios to communicate—even if they're floating in space right next to each other!

Why can't you stand on Uranus?

As an ice giant, Uranus doesn't have a true surface. The planet is mostly swirling fluids. While a spacecraft would have nowhere to land on Uranus, it wouldn't be able to fly through its atmosphere unscathed either. The extreme pressures and temperatures would destroy a metal spacecraft.

What Cannot go in the space?

Common items like salt and bread are banned from the International Space Station due to fears that they'll send floating pieces everywhere and potentially damage space equipment or accidentally get inhaled by astronauts. Basic eating, sleeping, and showering habits must also be modified.

Is there a crack in space?

There might be cracks in space-time, but humanity's telescopes can't see them. The cracks, if they exist, are old — remnants of a time shortly after the Big Bang when the universe had just shifted from a hotter, more alien state to the cooler, more familiar one we see today.

What is the hardest thing to find in space?

The NPR says that Astatine is so rare that it's never even been seen directly because if you managed to actually get enough of it together, it would vaporize itself with its own radioactive heat. In fact, on the entire Earth, there is only one ounce of Astatine.

Is gold rare in space?

Gold is rare on Earth in part because it's also rare in the universe. Unlike elements such as carbon or iron, it cannot be created within a star. Instead, it must be born in a more cataclysmic event —a short gamma-ray burst (GRB), like one that occurred last month.

What is the hardest thing in space?

Summary: A team of scientists has calculated the strength of the material deep inside the crust of neutron stars and found it to be the strongest known material in the universe.

What is the most harmless thing on Earth?

Can the universe RIP?

If dark energy remains unchanging, space will expand indefinitely while increasingly isolated stars will slowly fade away and go cold, a phenomenon referred to as Heat Death. And if dark energy keeps accelerating the expansion of the universe, space itself will eventually be torn apart in the Big Rip.

What is the deadliest living thing on Earth?

The mosquito is the single deadliest, most dangerous animal in the world and also one of the smallest. Mosquitoes are estimated to cause between 750,000 and one million human deaths per year.
