10 Astronomical Events That Will Happen In
Your Lifetime Number 10 Halley’s Comet Halley’s comet was named after astronomer
Edmond Halley, who calculated its period of orbit, it is the only known short-period comet
that is regularly visible to the naked eye from Earth. It is seen from Earth every 75-76 years and
so, technically, some lucky humans will get to see it twice in their lifetime. The first Halley’s Comet witnessed in the
space age – in 1986 – saw several spacecraft approach its vicinity to establish its composition.
High-powered telescopes also observed the comet as it swung by Earth. This fly-by provided the first observational
data on the structure of a comet’s nucleus, the mechanism of comets, and tail formation. But for those of you who missed it in 1986,
don’t worry because it’ll next appear in 2061. In the meantime you can see its remnants every
year. The Orionid meteor shower, which is spawned by Halley’s fragments, occurs annually
in October. Number 9 Near Earth Asteroid Flyby On April 13th, 2029, an asteroid called 99942
Apophis will pass between the Moon and Earth. Following its discovery in 2004, Apophis – which
is the size of three-and-a-half football fields – gathered the immediate attention of scientists
and the media. Initial calculations of its orbit by astronomers
indicated a 2.7 percent possibility of an Earth impact during the close flyby, so naturally
humanity feared for the end of the world. Fortunately though, further analysis by NASA
showed that Apophis will miss Earth by 31,300 kilometers. That’s actually closer than some
geostationary satellites, which orbit the Earth at a range of 36,000 km, but still far
enough away that we don’t need to fear for our lives. The flyby will be one for the record books,
as it will be the closest flyby of an asteroid of its size in recorded history – and it could
be the last chance astronomers have to get an up close look at Apophis for a very, very,
long time. Number 8 Solar Eclipse Okay, so we are slightly cheating with this
one, as solar eclipses can usually be seen somewhere on Earth each year, but 2027 has
something special in store. Solar eclipses occur when the Moon passes
between the Sun and the Earth, and it fully or partially blocks the Sun. In a total eclipse,
the disc of the Sun is fully obscured by the Moon, whereas in partial and annular eclipses
only part of the Sun is obscured. Typically, the duration of a total eclipse
is in the range of 2-6 minutes. But the longest solar eclipse to date lasted for 7 minutes,
28 seconds. It happened around 743 BC and would have been visible across Southern Africa. The next time a solar eclipse will have a
duration of this length will be on 16th July 2186, but most of us won’t be around to see
that. So instead set yourself a reminder for Monday
2nd August 2027, when the second longest solar eclipse of the century will occur. It will
have a maximum duration of 6 minutes and 23 seconds. It will pass through the Straits of Gibraltar
then across the North African coast, before dipping down to Yemen and Somalia. Number 7 Supernova On average, a supernova goes off twice a century
in a galaxy the size of the Milky Way, so scientists believe the magnificent astronomical
event is imminent. Supernovae are explosions that occur at the
end of life for stars more massive than our Sun. The massive star explodes when it has
used up all its hydrogen fuel and its core collapses just before it explodes, ejecting
most of its mass into space. They are triggered in two ways: either by
the sudden re-ignition of nuclear fusion in a compact star, or by the collapse of the
core of a massive star. The last one was spotted three decades ago,
on February 23rd, 1987. Nicknamed ‘Supernova 1987A’, it blazed with the power of 100
million suns for several months following its discovery and was one of the brightest
exploding stars in more than 400 years. But when will the next supernova occur? Well,
in 2013 astronomers from Ohio State University calculated that a supernova occurring within
our galaxy will be visible from Earth sometime in the next 50 years. It would be visible to telescopes but there’s
also a 20% chance that the supernova would be visible to the naked eye in the night sky. Number 6 Venus Occults Jupiter The last time Venus and Jupiter passed in
front of – or occulted – one another was nearly 200 hundred years ago, in January 1818. At this time in history, the Battle of Koregaon
between the British East India Company and the Peshwa faction of the Maratha Confederacy
was in full swing. Those mid-battle were probably not focusing
on the night sky, and even if they were, only observers in a remote island of Japan were
likely to see the occultation if they made a very special effort to look for it in the
bright morning twilight. Skip ahead to the 21st Century and for the
first time since 1818, on 22nd November 2065, Venus will pass directly before Jupiter and
form into a single, bright star, low down in the dawn skyline. Get your telescope ready for the event, because
it will be almost impossible to view with the naked eye, as it will be occurring during
the daytime and in close proximity to the sun. Number 5 Leonid Meteor Shower First noticed in 1833, this rare astronomical
phenomenon occurs when Earth passes through the orbit of periodic comet Tempel-Tuttle. Leonid meteors are caused by tiny meteoroids
that burn up in our planet’s atmosphere as Earth passes close to the dust-strewn orbit
of Tempel-Tuttle. Skywatchers have observed major Leonid meteor
showers every 33 years or so from 1833, when the meteor shower was said to have produced
a whopping 100,000 meteors an hour. Most years, Leonid storms are a minor event,
boasting no more than 10 to 15 shooting stars per hour. But on very rare occasions when
this dense filament of dust plows directly into our planet, meteor rates can soar to
100,000 per hour or more. If you want to catch this spectacular sight,
Tempel-Tuttle will next cause a major Leonid meteor shower in 2031. Number 4 Planetary Alignment The possibility of an alignment between all
of the planets in the solar system is very rare. The closest that the eight planets will
come to being aligned will occur on May 6th, 2492. But unless we figure out how to bring cryogenically
frozen corpses back to life, none of us will be alive to witness that astronomical event. On the bright side, space scientists estimate
that there will be a rare planetary alignment of Mars, Mercury, Venus, Jupiter, Saturn and
the crescent Moon on September 8th, 2040. That’s just 23 years away, and is much more
doable. Clustered well to the east of the Sun, the
planets will stage a breathtaking show at 7:30 pm, so mark your calendars now! Number 3 Supermoon In November 2016, stargazers worldwide enjoyed
a rare event, a Supermoon that was 14% bigger than its normal size. This was the closest
the moon had been to earth since January 26th, 1948. If you missed out on catching a glimpse of
the 2016 supermoon, there’s an even better astronomical event on the horizon. The closest
supermoon of the century will occur on December 6th, 2052, and it will be a once in a lifetime
experience. The term “supermoon” is typically defined
as a full moon that coincides with the lunar orb’s closest approach to Earth. In 2052 our celestial neighbor will be just
around 140,000 kilometers away. But what possible impact could it have on us? Well, many studies over the years have been
aimed at finding out any statistical connection between the moon – particularly the full moon
– and human biology or behavior. Reliable studies comparing the lunar phases
to births, heart attacks, deaths, suicides, psychiatric hospital admissions and epileptic
seizures among other things, have time and time again found little or no connection. Number 2 Transit Of Earth From Mars As of 2017, humans are not currently on any
other planets – well, as far as we know – so if a transit of Earth were about to occur
anywhere soon, we could not see it. The one noteworthy future exception, though, is Mars. For those of you unsure what we mean by ‘transit
of Earth from Mars’, it essentially means when the Earth passes directly between the
Sun and Mars, obscuring a small part of the Sun’s disc for an observer on the Red Planet. No one has ever seen a transit of Earth from
Mars, but if NASA’s plan to get humans living on Mars by the 2030s goes ahead, this could
be possible for the next such transit, which will take place on November 10th, 2084. This transit will be the first and only time
that this phenomenon will occur in the 21st century, with the next one predicted for 2394.
And by then, we should definitely have colonized the planet. Number 1 The Birth Of A Star Look up to the stars in 2022, because one
of the night sky’s most visible constellations, Cygnus, will be getting a new addition, and
everyone on Earth will be able to see it. Located about 1,800 light-years away, the
star system KIC 9832227 in Cygnus has long been a focus of study. For years, the pair of glittery specks in
this system have been circling around each other, moving closer and closer, and now astronomers
believe they will soon merge in an explosive event known as a nova. It’ll be a momentous occasion for scientists
as it’s the first time they have ever been able to predict the birth of a new star and
this will allow them to observe the process as it unfolds. For us average folks, it’s going to be pretty
damn extraordinary too, being able to witness a once in a lifetime astronomical event without
the use of a telescope. Thanks for watching today’s video, we hope
you enjoyed it! And if space is what you’re into why not check out 10 Unknown Signals

  1. that last nova of 2 stars have already taken place somewhere in 260AD or so
    its just that light is taking 1800years to reach us
    and if we use a powerful telescope from those stars to see earth
    we would probably see 260AD
    intresting know??!!!
