welcome to lab360 for all latest happenings from the world of astronomy
aliens are one of the most talked about topics in the space industry
the mere mention of extraterrestrial life generates ample amount of interest from space
fanatics you must have heard a lot of chatter about aliens living among us some would even go
as far as to claim that tech billionaire elon musk is an alien but these are just theories
apart from a few photos of ufos released by the pentagon we don't actually have any solid proof
that is about to change it's one thing reading about these theories on blogs and websites
but it's a whole another thing when the head of nasa confirms that extraterrestrials are out there
in a recent press conference when mr nelson was asked if aliens exist
he answered the short answer is yes but the longer answer is how big the universe actually is
he mentioned that nasa telescopes that are a million miles from earth
are collecting infrared spectrum light from 13.5 billion years ago
these rays traveled at roughly 300 million meters per second or 186 000 miles per second
we know that the universe was created roughly 13.8 billion years ago and it contains millions
if not billions of stars and suns we also know that there are billions of galaxies out there
is it possible that in such a vast cosmos conditions similar to those on earth might
have arisen of course it is possible and it would be very naive of us to believe otherwise that's
where our highly advanced space telescopes come in one of the main things that we will be using these
telescopes is to identify a bunch of exoplanets that are already revolving around other suns
mr nelson added that nasa will be able to have a closer look at these planets using the new james
webb telescope which was launched in december and identify the chemical composition of their
atmosphere as well as determine if they can have a positively habitable environment james webb is the
most powerful space telescope ever launched into space bringing with a greatly increased infrared
resolution and sensitivity it is regarded as the spiritual successor to the hubble observatory
this means that the telescope will be able to observe things that are too far away
dim or old for hubble to detect such as the universe's first stars and galaxies
this is just the beginning of our journey to solve the mysteries of the vast cosmos
and it's going to be a long one and now with the jwst on schedule to release its first
color photos and spectroscopic data on the 12th of july it's safe to say that a space
fans have a promising future ahead of us what do you guys think drop in your comments below

aliens ufos and life in outer space these are some topics that will be ever ambiguous
and the answers to them would only be found once we come in contact for terrestrial life
but when will that happen for years conspiracy theories about ufo sightings around the world have
surfaced only to be debunked by experts later some also believe that the united states is in contact
with aliens and that's why the highly classified area 51 remains inaccessible to the common people
but again these are just assumptions there is no concrete proof of extraterrestrial life
and for now it looks like we are alone in this vast universe traveling in the ever-marching wagon
of space-time but things are going to change drastically years of research have unlocked
many mysteries of the universe but the question whether aliens exist remains unanswered however
a former chief scientist from nasa believes that we will soon have a close encounter with aliens
yes you heard that right jim green who retired as nasa's chief scientist in january this year
told bbc many of them are in places much like the earth where we can receive the light from the sun
and we can have water and not only in liquid form frozen form and vapor form these are important
conditions we believe for life he added that they were making enormous progress and the
40 years that he was in the space industry they understood a lot of things they earlier couldn't
he also said that the james webb space telescope would be able to help them analyze atmospheres of
currently unreachable planets and nasa would be able to tease us with some images of such planets
jim called this a huge step forward and that we could see some astounding discoveries in the next
handful of years he also said that the telescope could help them compare the atmosphere of remote
planets to the ones they already know about we are going to be comparing these atmospheres to
the ones we know are they more venus-like are they more mars-like are they more earth-like he said
these studies could be the key to answering the question are we all alone in the vastness of this
universe it will be interesting to know what such studies reveal they could also confirm if
any of the ufo sightings in the past were real well we cannot wait all the best web
humanity is waiting with baited breath for your upcoming discoveries right guys what will be
your reaction if and when we find out that we are not alone let us know in the comments below
and don't forget to subscribe to lab360 because we bring you all the latest news and videos from
the world of astronomy according to statistics humans are most likely not alone in the universe
fermi's paradox can help us think about this possibility alien civilizations may have already
arisen prospered and become interplanetary given the abundance of stars expected to have planets
like earth where liquid water life and a moderate atmosphere support life aliens may find traveling
to other universes as simple as going from home to the nearest mcdonald's if this is the case we may
not need to colonize far away worlds in order to meet them they might make an attempt to contact us
it's both terrifying and intriguing to consider but how will aliens communicate with humanity
what would be the most effective manner for a technologically advanced alien civilization to
announce its arrival throughout the galaxy it could be to make it star systems planets dance
in a mathematical sequence many searches for intelligent life have been carried out thus far
such as probing for radio signals or megastructures around stars but the results have
been vague and have natural explanations that's why a scientist from france has proposed that
we hunt for planets orbiting in precise patterns that could only have evolved purposefully their
hypothesis is that a highly evolved civilization could alter the orbits of planets in its solar
system to serve as a beacon of its presence to an observer from the outside the gravitational
pull of asteroids might be used to slowly move planets into new places over thousands of years
causing them to have full orbits relative to one another in a specific fixed ratio or resonance
natural gravitational interactions produce such resonances for example jupiter's moon
io completes four jupiter orbits for every two europa orbits and one ganymede orbit forming a
two to one resonance chain similar patterns have been observed in other star systems although those
in which the ratios of each body differ rather than creating chains have never been observed as a
result the researchers believe aliens may organize their planets in sequences that are unlikely to
occur naturally such as a prime number series or the fibonacci sequence the researchers calculated
that these orbits may persist for 20 billion years before losing resonance even surviving the demise
of their host star the concept is similar to colossal structures on earth such as ancient
egypt's tallest pyramids which were built to last beyond the lifetime of a civilization
similarly this beacon has the potential to outlast its creators even if we did uncover
such a sequence it wouldn't prove intelligent life and it's possible that the civilization
behind it has long since vanished but the relics of it might still be found what do you guys think?
