What is the strangest object in space?

The dwarf planet Haumea, which orbits in the Kuiper Belt out beyond Neptune, is already unusual. It has a strange elongated shape, two moons and a day that lasts only 4 hours, making it the fastest-spinning large object in the solar system.

What is the weirdest thing found in space?

What is the rarest thing from space?

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 most unknown thing in the universe?

The rest of the universe appears to be made of a mysterious, invisible substance named dark matter (25 per cent), and a force that repels gravity known as dark energy (70 per cent). The exotic unknown substance named dark matter doesn't appear to absorb, reflect or emit light, rendering it 'invisible'.

What is the weirdest thing in the galaxy?

The Hole in the Galaxy

Its most unusual feature, though, is a dark “void” on one side of the galaxy's core, which looks like a hole has been punched through the disk. The region contains a few old, faint stars but almost no young, bright ones.

The Strangest Object in Space

Why can't we see a 15 billion year old galaxy?

Answer and Explanation: Because the universe is estimated to be less than 14 billion years old, conventional wisdom would indicate that we can't see a galaxy 15 billion light-years away because, if anything exists 15 billion light-years away at all, its light hasn't had enough time to reach us.

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.

What is the darkest secret of the universe?

What is dark energy? It's one of the universe's biggest mysteries: more remains unknown than known about dark energy. It affects the universe's expansion, so physicists are able to infer that dark energy makes up roughly 68% of the universe and it appears to be somehow tied to the vacuum of space.

What are some scary facts about space?

What is the hardest thing to find on Earth?

Diamond is the hardest naturally occurring substance found on Earth.

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.

Has anything been lost in space?

Apart from the rare moonwalk or testing of a manned maneuvering unit (pictured above) these extravehicular activities, or EVAs, are often laser-focused on making repairs or setting up science experiments. To date, no astronaut has ever been 'lost' to space during one, but there have been a couple close calls.

Is there no smell in space?

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 is forbidden in space?

The Outer Space Treaty

There is no claim for sovereignty in space; no nation can “own” space, the Moon or any other body. Weapons of mass destruction are forbidden in orbit and beyond, and the Moon, the planets, and other celestial bodies can only be used for peaceful purposes.

What is the biggest mystery in space?

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.

What is the most violent thing in space?

Thousands of times more energetic than ordinary exploding stars, their visible light as bright as a million galaxies, gamma-ray bursts are the most violent events in the universe, and radiation from one of these events reaches the vicinity of Earth at a rate of about one a day.

What if I scream in space?

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.

Can you cry tears in space?

However, as astronaut Chris Hadfield notes, in microgravity, "your eyes make tears but they stick as a liquid ball." In other words, astronauts technically can't cry. Sure, you can get a watery substance to come out of your eyes, but it doesn't fall like it ordinarily does on Earth.

How much of the universe will we never see?

Even if we traveled at the speed of light, we'd never catch up to these galaxies.

Will the universe turn black?

The universe will become extremely dark after the last stars burn out. Even so, there can still be occasional light in the universe. One of the ways the universe can be illuminated is if two carbon–oxygen white dwarfs with a combined mass of more than the Chandrasekhar limit of about 1.4 solar masses happen to merge.

Will the universe go black?

The known laws of physics suggest that by about 10¹⁰⁰ (the No. 1 followed by 100 zeros) years from now, star birth will cease, galaxies will go dark, and even black holes will evaporate through a process known as Hawking radiation, leaving little more than simple subatomic particles and energy.

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!
