Astrobiology: The Story of our Search for Life in the Universe
Astrobiologists study the origin, evolution, and distribution of life in the universe. This includes identifying evidence left behind by life that once survived on the ancient Earth, and extends to the search for life beyond our planet.
When looking for signs of life on other worlds, what are they looking for?
Things called biosignatures. For example, when you sign a piece of paper, your signature is evidence of your existence. Similarly, biosignatures are anything that can prove that life was once, or is, present in an environment.
Tumblr media
If we were very very lucky, we might spot something we know is life with a powerful telescope or receive a "phone call" or radio signal from alien civilizations. Those types of biosignatures would be obvious. But they would only let us identify advanced life.
Tumblr media
For most of Earth’s history (billions of years), single-celled life like bacteria and archaea have been around. Humans have only been making radio transmissions for hundreds of years. So we have a better chance of finding life if we look for signs that have been around for very long periods of time.
Tumblr media
Patterns in ancient rocks that were created by life are a great example. That can be anything like a dinosaur footprint or structures built by microorganisms, like stromatolites.
Tumblr media
Molecules can also be biosignatures, like DNA left behind for detectives to discover. But DNA doesn’t last very long on its own in most environments, so other molecules like lipids (like natural oils, wax, and fat) might be a better choice if you are looking for signatures of life from millions (or billions) of years ago.
Even the balance of gases in a planet’s atmosphere can be a sign of past or present life. On Earth, biology plays a major role in maintaining the delicate composition of gases like nitrogen, oxygen, and carbon dioxide in the air that we breathe.
These are just a few examples of signs astrobiologists look for when searching for life amongst the stars! Research into these biosignatures inform many of our biggest missions, from observatories like the Hubble Space Telescope and the Webb Space Telescope to our Mars Sample Return endeavor.
Want to learn more about the search for life? Check out the latest issue of our comic-book style graphic history novel, Astrobiology: The Story of our Search for Life in the Universe. This new chapter is all about biosignatures.

Harry Styles offhandedly mentioned he thinks the universe is a frog and you bet your ass Tumblr churned out so many Homestuck memes like one of him on a TED Talk stage with that Homestuck frog galaxy panel on the screen.

"your desires are you" explanation
context: before i go ahead with the explanation, i would like to tell you the story of abdullah the ethiopian mystic ( yes, he's neville's guru ).
neville and abdullah met one day for dinner, long after the "i'm in barbados" incident. abdullah ordered huge shots of rye, a whole ªss meal, an ale, and a big bowl of ice cream. neville was shocked at the enormous amount of food being consumed by ab. he asked, "how can you do that?"
his reply was simple. "you couldn't do it... it would poison you, because you have quibbles. " and then he proceeded to say that god made everything. everything is god.
how?
people say that there's no logic in manifestation. but in reality, manifestation is extremely logical.
every. bit. of. it. is. common sense.
when the big bang happened, everything in the universe was made up of the same contents but in different composition ( i'm not a science student so not getting into the details, you can search it up ). what ab meant while saying, "everything is god", is that each and every person and each and every thing ( including your desires ) are made up of the same contents. atoms. the constituent units of everything in this universe. they occupy space and have mass. a bunch of atoms made up your cells, and you were made of those bundle of cells. your sp is made up of those same atoms, which make up you. your sp and you are the same. your assumptions about them are getting reflected in your reality and if you change that, you change them. as easy as that.
your desires are you.
creation is finished. everything you want already exists. god made each and all of your desires with the same substance as you when they created this universe and you.
conclusion:
even some of neville's rules are flawed asf. he made his own rules so should you.
stop fussing about your desires. your imagination ( a.k.a. the 4D ) is the ultimate reality. what you focus on grows.
the 3D circumstances were created first in your mind and then materialized so they are only showing you what needs to be changed in your mindset.
your desires ( persons, things, etc. ) are all you and they reflect your assumptions like a mirror. so create assumptions for yourself, that benefit you and your life so that you can live a comfortable and easy life.

A beautiful emission nebula and star cluster can be found far in the southern skies within the constellation Carina. Stars from NGC 3572 are toward top center in the telescopic frame that would measure about 100 light-years across, while the cluster's estimated distance is 9,000 light-years. The visible interstellar gas and dust is part of the star cluster's natal molecular cloud. Dense streams of material within the nebula, eroded by stellar winds and radiation, trail away from the energetic young stars. They are likely sites of ongoing star formation. In the coming tens to hundreds of millions of years, gas and stars in the cluster will be dispersed by gravitational tides and by violent supernova explosions that end the short lives of the massive cluster stars.
