Did you know that...(Weirdest Astronomy Facts)
*Sniffing nose* Mhhh...what have we here?
Rum and raspberries flavour... Oh, hey! Welcome to INSANE CURIOSITY!
Did you know that clouds at the centre of Milky Way smell of rum?
What you're about to see is not a video. It is a bunch of weird facts.
Of them, we gathered and brought you many: the best ones.
Oh. I almost forgot:
your zodiac sign is probably wrong. I'm sorry.
Follow me on this video about Astronomy facts. You can watch with your turtle: it will be
amazed to know that some of its friends flew around the Moon.
Did you know that... Clouds at the centre of Milky Way smells of
rum and raspberries?
Finding amino acids in interstellar space is a Holy Grail for astrobiologists, as this
would raise the possibility of life emerging on other planets after being seeded with the
molecules. In the latest surveys, astronomers sifted
through thousands of signals from Sagittarius B2, a vast dust cloud at the centre of our
galaxy. While they failed to find evidence for amino acids, they did find a substance
called ethyl formate, the chemical responsible for the flavour of raspberries.
Curiously, ethyl formate has another distinguishing characteristic: it also smells of rum.
Did you know that...one teaspoonful of neutron star would weigh way more than the entire
human population?
A neutron star’s density is mind-boggling. These stars are composed almost entirely of
neutrons packed together in a tiny radius. Just a teaspoonful of this material would
weigh over a trillion kilograms — more than the weight of the entire human population
(which reaches a few hundred billion kilograms). To make something as dense as a neutron star,
the whole of humanity would need to be crammed into space the size of a sugar cube.
On average, gravity on a neutron star is 2 billion times stronger than gravity on Earth.
In fact, it's strong enough to significantly bend radiation from the star in a process
known as gravitational lensing, allowing astronomers to see some of the back sides of the star.
The power from the supernova that birthed it gives the star an extremely quick rotation,
causing it to spin several times in a second. Neutron stars can spin as fast as 43,000 times
per minute, gradually slowing over time, falling in the so-called “pulsar graveyard”, where
they are no longer detected.
Did you know that...Neptune has only completed one orbit around the Sun since its discovery?
Neptune’s average orbital distance from the sun is enormous. In fact, this distance
is about 30 times greater than the corresponding value for Earth.
Neptune is the eighth and farthest planet from the sun.
Neptune was first observed in 1846. Since its discovery, the blue gas giant has
only completed one orbit around the Sun.
Did you know that...soon or later we will say goodbye to Polaris?
Polaris, our North Star, isn’t leaving us anytime soon—at least not for another 12,000
years. But when it does, the star Vega will replace it. Why? It’s all about the rotation
of the Earth. As our planet’s axis changes over a very long 26,000-year cycle, the north
eventually shifts to different stars. It won’t be the first time Vega gets the starring role
in our night sky; it was the North Star several thousand years ago.
Actually, for the same reasons, your zodiac sign is probably wrong.
Do you want to know why?
"Before finding out why your zodiac sign is wrong, be sure to like or dislike the video

Roughly speaking, the Sun appears against a different constellation every new Moon,
the stars forming a distant backdrop to the Sun. Though the stars are not visible during
daytime, you can know what constellation the Sun is in by looking at the nighttime sky.
There you will see the opposite constellation. The main reason astrological signs fail to
line up with the zodiac, though, is a wobble in the Earth’s rotational axis called precession.
As a result of its rotation, the Earth bulges slightly at the equator, not unlike how a
skater’s skirt fans out as she spins. The gravity of the Moon and Sun pulls on the bulge,
which causes the Earth to wobble like a top. The wobble causes the Earth’s axis, which
is the centerline around which it rotates, to swing in a slow circle over the course
of 25,800 years. This movement alters the view of the zodiac
from Earth, making the constellations appear to slide to the east, roughly a degree per
human lifetime. Though slow, precession was discovered with the naked eye by Hipparchus
of Nicaea around 150 B.C. In ancient times, the vernal equinox – or
the first day of spring – was in Aries. Due to precession, it moved into Pisces around
100 B.C., where it is now and will remain until A.D. 2700, when it will move into Aquarius
and so on. Over the course of 25,800 years, it will eventually return to Aries and the
cycle will begin again. Do you want to know what constellation was
the Sun in on your birthday? You can start counting from this:
Aries: April 19-May 14 Taurus: May 15-June 20
Gemini: June 21-July 20 and so on!
As you can see, your zodiac sign is probably wrong.
Did you know that...We've had turtles orbiting the moon?
The Zond 7 was a probe Soviet of the Zond program. The mission involved studying the
Moon and space around it, obtaining colour photographs of the Earth and the Moon from
various distances, and testing the probe's systems.
A biological payload of turtles, wine flies, mealworms, plants, seeds, bacteria, and other
living matter was included in the flight. Additionally, according to the Russian Academy
of Sciences, in the pilot's seat was a 175 cm tall, 70 kg mannequin containing radiation
detectors. The spacecraft was planned as a precursor
to crewed lunar spacecraft. It represented the first successful Soviet circumlunar Earth-return
mission
Did you know that...the Moon is getting farther away every year?
The ongoing Lunar Laser Ranging experiment or Apollo landing mirror measures the distance
between surfaces of Earth and the Moon using laser ranging. Lasers at observatories on
Earth are aimed at retroreflectors planted on the Moon during the Apollo program (11,
14, and 15), and the two Lunokhod missions. Laser light pulses are transmitted and reflected
back to Earth, and the round-trip duration is measured. The lunar distance is calculated
from this value. As detected, the Moon is spiralling away from
the Earth at an average rate of 3.8 cm (1.5 in) per year
Did you know that, As seen from Earth, stars twinkle, but solar system planets don’t?
Stars twinkle because … they’re so far away from Earth that, even through large telescopes,
they appear only as pinpoints. And it’s easy for Earth’s atmosphere to disturb the
pinpoint light of a star. As a star’s light pierces our atmosphere, every single stream
of starlight is refracted – caused to change direction, slightly – by the various temperature
and density layers in Earth’s atmosphere. You might think of it as the light travelling
a zig-zag path to our eyes, instead of the straight path the light would travel if Earth
didn’t have an atmosphere. Planets shine more steadily because … they’re
closer to Earth and so appear not as pinpoints, but as tiny disks in our sky. You can see
planets as disks if you looked through a telescope, while stars remain pinpoints. The light from
these little disks is also refracted by Earth’s atmosphere, as it travels toward our eyes.
But – while the light from one edge of a planet’s disk might be forced to “zig”
one way – light from the opposite edge of the disk might be “zagging” in an opposite
way. The zigs and zags of light from a planetary disk cancel each other out, and that’s why
planets appear to shine steadily. You might see planets twinkling if you spot
them low in the sky. That’s because, in the direction of any horizon, you’re looking
through more atmosphere than when you look overhead.
If you could see stars and planets from outer space, both would shine steadily. There’d
be no atmosphere to disturb the steady streaming of their light.
Can you figure out which objects are stars and which are planets just by looking for
the twinklers vs the non-twinklers? Experienced observers often can, but, at first, if you
can recognize a planet in some other way, you might notice the steadiness of its light
by contrasting it to a nearby star.
Did you know that Before NASA, there was NACA?
The National Advisory Committee for Aeronautics (NACA) was formed on March 3, 1915, with a
charter to "supervise and direct the scientific study of the problems of flight, with a view
to their practical solution." With luminaries like Orville Wright as members, the group
was on the cutting edge of technology in the early decades of flight, before eventually
being absorbed by NASA in 1958.
Did you know that... No one has gotten lucky in space?
Eh? Eh? Wink-wink..in space? NASA says no humans have had sex in space.
Human sexual activity in the weightlessness
of outer space presents difficulties due to Newton's third law. According to the law,
if the couple remains attached, their movements will counter each other. Consequently, their
actions will not change their velocity unless they are affected by another, unattached,
object. Some difficulty could occur due to drifting into other objects. If the couple
has a combined velocity relative to other objects, collisions could occur. There have
been suggestions that conception and pregnancy in off-Earth environments could be an issue.
As of 2009, with NASA planning long-term missions for lunar settlements with goals to explore
and colonize space, the topic has taken a respected place in life sciences. Scientist
Stephen Hawking publicly concluded in 2006 that possibly human survival itself will depend
on successfully contending with the extreme environments of space.
Did you know that...Andromeda Galaxy is the only extra-galactic object you can see with
you naked eyes from Northern Hemisphere? If you can spot the Andromeda Galaxy with
your naked eyes, you can see something 2.537.000 light-years away.
If you want to try to spot it, you have to find Cassiopeia first.
Cassiopeia appears low in the northeast sky at nightfall and early evening then swings
upward as evening deepens into the late night. In the wee hours after midnight, Cassiopeia
is found high over Polaris, the North Star. Note that one half of the W is more deeply
notched than the other half. This deeper V is your “arrow” in the sky, pointing to
the Andromeda galaxy.
Did you know that...Driving a car to the nearest star at 70 km/h would take about 65,5 million
years?
Proxima Centauri, the closest star to our own, is still 40,208,000,000,000 km away.
(Or about 268,770 AU.) When we talk about the distances to the stars, we no longer use
the AU or Astronomical Unit; commonly, the light-year is used. A light-year is the distance
light travels in one year - it is equal to 9.461 x 1012 km. Alpha Centauri A & B are
roughly 4.35 light-years away from us. Proxima Centauri is slightly closer at 4.25 light-years.
A car going at 70 km/h travels in a year about 613.200 km, so if we wanted to use the “car
year”, we would find it would take about 65.570.776,3 car years.
