5120 exoplanets in 3790 systems, and yet there is still no trace of a cosmic Earth twin.
As is well known, the planetary search is always subject to the hope of one day coming across a Celestial body that can be classified as clearly habitable.
The exoplanet search has as yet, however, drawn a completely different picture.
Some bizarre worlds have been added on the star maps that impressively demonstrate what unusual fruit the universe can produce.

THE SUPER SATURN
Foreign the super Saturn.
To start off today’s post, we have to give Saturn some bad news.
It’s no longer the most spectacular ringed planet in the universe.
A few years ago, researchers managed to identify a distant Celestial body that mercilessly dwarfs our Saturn in size and dimensions, approximately 430 light years far away from our terrestrial Homeland.
J1407b calls a ring system- its own, which possesses a diameter of a fabulous 75 million miles.
In comparison, Saturn’s outermost ring has a diameter of only 600 000 miles.
While our iconic ring planet is still orbited by thousands and thousands of individual orbits, its Cosmic counterpart has just 37, but incomparably larger.
As is so often the case, J1407b did not reveal itself directly to astronomers, but Drew attention to itself through fluctuations in the brightness of its parent star.
While the super Saturn passed by its young, 16 million year old Central Star, there was a conspicuous flicker when viewed from the terrestrial point of view.
Unlike other exoplanets detected by the transit method, however, these Luminosity changes lasted an unusually long time.
After the 56-day spectacle had been documented and analyzed in detail, it was clear that we were dealing with one of the most unusual exoplanets ever and, moreover, with one that was not traveling alone.
The experts discovered a conspicuously large gap within the ring Network.
Therefore, the conclusion is obvious: that an almost earth-sized Moon orbits this planet at a distance of 38 million miles.
It’s very likely that the system is currently in a transitional phase.
In the future, new moons will gradually form within the circumplanetary disk.
Astronomers have long suspected that Saturn Ii had a comparably large ring system in its early stages, which steadily rank as the moon, formed Gj 504b, the gas giant Gj-504b, or, in other words, the pink planet.
After considering the key data of Jupiter’s approximate size and location in the constellation Virgo, a fundamental question must be addressed: what gives the exoplanet its unmistakable blaze of color?
In this regard, Nasa states that the Striking coloration is due to the gas Giant’s fairly young age, or, more precisely, its average temperature of 464 degrees Fahrenheit.
Planets are still extremely hot after their birth, a condition which initially lasts for quite some time.
Before Gj 504b has finished its material accretion and cools down, some millions of years will pass.
Kepler-37b, the super Saturn presented at the beginning of this article, proves once more which unimaginable Dimensions the structures of the universe can assume.
However, we should not forget that also the other end of the cosmic flagpole holds some remarkable representatives, in this case, the representative as the scientific designation kepler-37b, and embodies the so far smallest known exoplanet.
This planetary dwarf has a diameter of just 2423 miles, which makes it only slightly larger than our Earth’s Moon.
Added to the star charts in February 2013, the celestial body, 210 light years away from us, is unlikely to Harbor extraterrestrial life, however.
For example, the data collected so far indicate that kepler-37b has no atmosphere.
In addition, the surface temperature amounts to scorching hot 797 degrees Fahrenheit due to the small distance between mother star and planet Trace 4.. from one size extreme to the other, as is well known, no other member of our domestic planetary system approaches the dimensions of Mighty Jupiter.
Earth would theoretically fit into the gas giant more than 13 000 times over.
However, Trace 4 could only smile tiredly about such Dimensions.
The exoplanet in the constellation Hercules trumps Jupiter in terms of size by 70 percent.
At the same time, however, it has only 92 percent of Jupiter’s mass being composed mainly of hydrogen.
In combination with the surface temperature of 2400 degrees Fahrenheit, this results in a problem for the experts that should not be underestimated.
Trace Iv should not actually exist in this form.
Regarding its mass and temperature, it’s simply too large for a gas planet.
What causes this mysterious circumstance is still written in the stars:
Who of you still knows the 90s trash classic Water World?
Well, without knowing it, the protagonists, Kevin Costner and company, gave us a foretaste of the nature of Gj 1214b.
Investigations of the Hubble Space Telescope revealed that the atmosphere of the planet, which is 48 light years away, possibly consists mainly of water vapor.
Against this background, it’s assumed that also the celestial body itself is composed to a large extent of water.
Should this thesis be confirmed, one day, The Strange World in the constellation of the serpent Bearer would become the first known ocean planet in history.
Up to now, these planets whose surfaces are completely covered by water existed only in theory.
We may be curious, therefore, what the future brings.
METHUSELAH (PSR J1623-2631 B)
Methuselah- Psr J1623-2631b.
In expert circles, the next exoplanet carries this bulky designation, Psr J1623-2631b.
For time reasons, we would like to make do, however, with the nickname of the celestial body, which lets us look at the same time deeply into its background.
Methuselah, with an estimated age of a legendary 12.7 billion years, this is no less than the oldest existing exoplanet of all, almost three times older than our Earth.
Methuselah is at home in a double star system which is composed of a pulsar and a white dwarf.
What is true for the actual planet can also be applied to its Discovery history.
It’s one of the first exoplanets discovered in the early 1990s.
You could call wasp 12b a glowing diamond.
In fact, this hot Jupiter orbits so closely around its Central star that it takes just 1.1 days to complete one orbit.
Consequently, surface temperatures of more than 3990 degrees Fahrenheit results.
Shortly after the discovery of the exoplanet in 2008, investigations by the Spitzer Space Telescope revealed a startling detail.
For example, a very high concentration of carbon was recorded on wasp 12b, suggesting that the planet’s core is composed of graphite or even Diamond.
However, the presumed sparkling inside will soon come to an end.
In an estimated 10 million years, the celestial body will have been consumed by its star.
But this is still not the last feature that makes wasp 12b one of the most intriguing exoplanets known.
As observations by the Hubble telescope show.
It is also one of the darkest objects detected in the universe so far.
It’s even darker than asphalt.
THE SPEED PLANET (PSR J1719-1438B)
The Speed Planet Psr J1719-1438b. 2 hours 10 minutes and 37 seconds: this is the almost ridiculously low orbital period of our next exoplanet, Psr J1719-1438b, informally known as the speed Planet.
It orbits its host star in a distance of just 373 000 miles for classification.
In theory, the orbit of this planet would fit effortlessly into the sun.
Also, the gravitational fixed point of the celestial body shows itself from an unusual side.
It is a millisecond Pulsar, or in other words a stellar core that rotates around its own axis at an insane speed.
The planet itself consists, with high probability, of crystalline Carbon or Diamond.
However, experts are still arguing whether the little word planet is appropriate in this case at all.
THE GLASS RAIN PLANET (HD 189733B)
Some researchers prefer the designation object of planetary mass or, more precisely, carbonaceous white dwarf of ultra low Mass. the glass rain planet, Hd 1897 33b.
The following and last Celestial body, Hd 1897 33b, May Adorn itself with an important title.
It is the first exoplanet on which methane gas has been detected.
Located in the constellation of fox and about 64 light years away from us, this distant world was detected in Autumn 2005.
The planet takes just two days to orbit its ancestral mother star, resulting in a surface temperature of more than 1800 degrees Fahrenheit.
Besides its distinction as methane gas debutant, the celestial body also Advanced to the first exoplanet whose actual color could be determined.
The object appears in a striking blue hue, very reminiscent of the appearance of our Earth.
However, in this case, the coloration is not caused by water, but by the reflections of thousands of gas particles whipping through the atmosphere at a speed of up to 4 350 miles per hour.
