It is "super venus"!

Ever since the first alien world, revolving around a distant Sun-like star, was detected nearly twenty years ago, the discovery of an Earth-like exoplanet has been the Holy Grail of planet-hunting astronomers. No Earth analog has yet been identified, so the search continues.

“We only know of one star that hosts a planet with life, the Sun. Finding a planet in the living area around a star like our Sun is an important milestone in finding truly Earth-like planets,” Dr. Thomas Barclay said in a NASA statement dated April 18, 2013. Press release from the Jet Propulsion Laboratory (JPL). Dr. Barclay, a NASA planet search scientist, Kepler Space Telescopeit’s in the Bay Area Research Institute in Sonoma, California, and lead author of a paper describing the discovery of the Kepler-69 planetary system that was published in the Astrophysical Journal. The system contains two planets: Kepler-69b Y Kepler-69c. Kepler-69c it was classified as a “super-Earth”. A “super Earth” is generally defined as an exoplanet with a mass between 1 and 10 Earth masses.

In the moment of Kepler-69c discovery, it was thought to comfortably orbit its star at the distance of Goldilocks, where liquid water might exist. This lucky location, not too hot, not too cold, but Just fine–it’s called from a star living area. Where there is liquid water, there is the possibility, though not the promise, of life. In addition to having liquid water on its surface, a habitable exoplanet must also have a life-friendly atmosphere and a well-behaved parent star.

The search for exoplanets, which orbit other stars beyond our Sun, has proven to be an extremely difficult quest, and their latest discovery nearly a generation ago clearly represents one of humanity’s proudest moments. There are, as of this writing, over 800 confirmed exoplanet discoveries–objective It is very likely that there are billions more alien worlds yet to be discovered that inhabit our Milky Way! Some of the confirmed alien worlds are eerily familiar, resembling planets in our own Solar System. Others, however, are so strange that they are unlike anything astronomers have thought might exist.

Since the first discovery of an exoplanet orbiting a Sun-like star in 1995, discoveries continue to accelerate at a breakneck pace. Planet hunters continue to improve their techniques, while carefully studying the accumulated data collected by instruments both on Earth and in space. The largest batch of alien worlds yet to be confirmed, in the foreseeable future, should be captured by the unfortunate NASA. Kepler space telescope. Kepler it successfully racked up a slew of exoplanet discoveries, both confirmed and potential, before coming to a standstill in May 2013, when the second of its four orientation-maintaining reaction wheels stopped working.

The Kepler-69 system

In April 2013, astronomers announced that Kepler had discovered two new planetary systems. One of the newly discovered systems then was the Kepler-69 while the other was Kepler-62 system. Tea Kepler-62 system sported five planets: 62b, 62c, 62d, 62e Y 62f. Three planets inhabiting the two newly discovered systems were designated “super-Earths”: Kepler-62e, Kepler-62fY Kepler-69c.

Kepler-69c it is estimated that it is approximately 70% larger than the size of our planet. However, astronomers remain unsure of the composition of Kepler-69cdespite the fact that it is known to have an orbit that revolves around its star every 242 days, a distance comparable to the orbit of the planet Venus around our Sun.

Tea Kepler-69 The parent star of exoplanets belongs to the same stellar class as our Sun, called type g It is about 93% the size of our Sun and 60% of its luminosity. Tea Kepler-69 The system is located about 2,700 light-years from Earth in the constellation Cygnus.

“Planet detection and confirmation is a huge collaborative effort of talent and resources, and requires the expertise of the entire scientific community to produce these tremendous results. Kepler has brought a resurgence of astronomical discovery and we are making excellent progress in determining whether planets like our own are the exception or the rule,” noted Dr. William Borucki on April 18, 2013 JPL press release. Dr Borucki is Kepler NASA principal investigator scientist Ames Research Center at Moffett Field, Calif. Dr. Borucki is also the lead author of the Kepler-62 article published in April 2013 in the magazine Science.

It’s “SuperVenus”!

Although Kepler-69c Originally thought to be a “super-Earth”, dancing merrily around its star in the comfortable Goldilocks region where liquid water might exist, astronomers now think this may not be the case. Kepler-69c it is more likely to be a hostile world, like Venus in our own Solar System. Venus is a ball of hell the size of Earth; an inhospitable world lashed by raindrops of corrosive sulfuric acid, lashed by violent volcanic eruptions, and so hot on its creepy, creepy, glowing red surface that it could melt lead. In fact, Venus literally has the hottest surface of any planet in our Solar System! If it were possible for an earthling to stand on Venus, the Sun would be seen to rise in the west, travel slowly across the sky, and then set in the east, exactly the opposite of what happens on our own planet. venus rotates backward compared to the other planets in our Sun’s family. Viewed from above its north pole, Venus would appear to rotate clockwise. The pressure on the surface of Venus is comparable to being 900 meters underwater! The infernal planet is also as dry as a bone; a truly horrific example of the “runaway greenhouse effect” in action: life cannot possibly evolve on Venus!

Although the most recent measurements indicate that Kepler-69c a “super-Venus” is more likely than a “super-Earth”, the alteration of the planetary state is largely just a reflection of the difficulties that arise over how to define the living area surrounding a star

“There are a lot of unanswered questions about habitability,” said Dr. Lucianne Walkowicz in a press release dated October 21, 2013.. Dr. Walkowicz, an astrophysicist, is a Kepler member of the scientific team at Princeton University.

“If the planet gets radiation all the time due to flares from its parent star, the surface might not be a very nice place to live-energy radiation, so maybe life could thrive in the oceans,” he continued. explaining Dr. Walkowicz.

Close examination of the planet’s chemistry now suggests that Kepler-69c actually skirts your star just outside the habitable zone innermost edge.

“[M]Molecules in a planet’s atmosphere will absorb a certain amount of energy from starlight and radiate the rest outward. The amount of this trapped energy can mean the difference between a turquoise sea and erupting volcanoes,” NASA announced in a follow-up news release issued in June 2013.

The astronomers also studied the energy output of the parent star, as well as Kepler-69c they orbit around it, to make their subsequent determination. However, astronomers still find it difficult to say for sure whether or not the planet is in the living area around your star. It is still necessary to observe the planet’s atmosphere, but it is difficult for the telescopes available today to detect “signatures” of oxygen, water, methane or carbon dioxide, which could hint at the presence of life.

Even though the next James Webb Space Telescope, scheduled for launch in 2018, can study the atmospheres of exoplanets, was built to detect planets that are much larger than Earth. Determination of the nature of Kepler-69c the atmosphere may have to wait for an even more sensitive telescope, according to NASA,
