Newest Planet Discoveries: 2. HD 209458b (Osiris) 

HD 209458b, also known as Osiris, is an exoplanet located approximately 150 light-years away from Earth in the constellation Pegasus.  

This celestial object is known for its remarkable characteristics that have piqued the interest of astronomers and researchers around the world.  

Osiris, being a gas giant, belongs to the class of exoplanets known as hot Jupiters. These exoplanets are characterized by their large size and close proximity to their parent stars. 

One of the defining features of Osiris is its close orbit around its host star, HD 209458. It completes a full revolution around its star in just 3.5 days, which is incredibly quick compared to the approximately 365 days it takes for Earth to orbit the Sun.  

This tight orbit has caused Osiris to become tidally locked, meaning that one side always faces its star while the other remains in perpetual darkness.  

Consequently, the temperature difference between the two hemispheres is extreme, with the day side reaching scorching temperatures of over 1000 degrees Celsius. 

The extreme heat on Osiris has led to the detection of various atmospheric phenomena, particularly the presence of sodium in its atmosphere.  

This was determined through the study of the planet’s atmosphere using a technique called transmission spectroscopy.  

By examining the changes in the spectrum of starlight as it passes through the planet’s atmosphere, researchers were able to identify the unique signature of sodium absorption. 

In addition to sodium, other elements and molecules have been detected in Osiris’ atmosphere, including helium, water vapour, and carbon dioxide.  

These findings shed light on the planet’s atmospheric composition and provide valuable insights into the atmospheric chemistry and processes happening on hot Jupiters. 

Further exploration of HD 209458b (Osiris) will undoubtedly unravel more intriguing details about its formation, evolution, and atmospheric dynamics.  

The continued study of hot Jupiters like Osiris expands our understanding of planetary systems beyond our own and encourages us to question the mysteries that lie within the vast expanse of the universe. 

Newest Planet Discoveries: 3. 55 Cancri e (Janssen) 

55 Cancri e (Janssen) is a rocky planet that orbits very close to its star, making it a scorching hot and uninhabitable world.  

It was discovered in 2004 and has a mass and radius double that of Earth, earning it the nickname “Super-Earth.”  

Despite its hostile conditions, scientists have found evidence of a possible atmosphere on the planet, which makes it interesting to study. It also has a very short orbital period of just 18 hours, which means it completes one orbit around its star in less than a day. 

Additional information reveals that 55 Cancri e (Janssen) is located in the constellation of Cancer and its distance from Earth is 40 light years. Due to its proximity to its host star, the planet is tidally locked, which means one side of the planet always faces the star while the other side is in eternal darkness.  

This causes very extreme temperature differences on the planet, with one side reaching temperatures of up to 2,400°C, while the other side can fall to as low as -170°C.  

These conditions have made it one of the most challenging objects to observe in the universe. Despite this, ongoing research continues to shed light on the fascinating characteristics of this hot, rocky planet on the edge of our understanding. 

Newest Planet Discoveries – Water Worlds: Diving into the Depths 

In the vast expanse of space, where countless newest planet discoveries await, scientists have recently unearthed some truly intriguing water worlds.  

Newest Planet Discoveries: 1. WASP-39 b 

WASP-39 b is an exoplanet orbiting the star WASP-39, roughly 700 light-years away in the constellation of Virgo. Its mass is similar to that of Saturn, but its radius is nearly twice as large, suggesting it is an inflated planet.  

WASP-39 b is classified as a ‘hot Saturn’ because of its size and proximity to its star. It orbits its star every four days, and its atmosphere is extremely hot, with temperatures reaching up to 1,500 degrees Celsius.  

This scorching heat creates unusual atmospheric conditions, such as clouds made of aluminium oxide instead of water, giving the planet a striking appearance. 

Recent observations of WASP-39 b suggest that it may have a near-polar orbit, which means it could be tilted at an extreme angle relative to its star.  

This could cause significant variations in its atmospheric temperature and composition, making it an interesting target for further study.  

WASP-39b has been studied to determine the presence of various compounds, including water vapour (H2O). Water vapour detection in exoplanet atmospheres is a significant finding as it provides insights into the planet’s composition and the potential for habitability. 

In the case of WASP-39b, observations and studies have indeed detected the presence of water vapour in its atmosphere.  

This discovery was made using spectroscopic techniques, which involve analyzing the light that passes through the exoplanet’s atmosphere as it transits in front of its host star. 

The detection of water vapour in WASP-39b’s atmosphere is a crucial piece of information, as it helps scientists better understand the composition and conditions of the exoplanet. 

However, it’s important to note that WASP-39b is a gas giant and not a rocky planet like Earth, so its atmosphere is primarily composed of hydrogen and helium with other trace elements and compounds like water vapour. 

The presence of water vapour in exoplanet atmospheres is a significant factor in the search for potentially habitable worlds and the study of planetary atmospheres beyond our solar system. 

Newest Planet Discoveries: 2. Kepler-138 c and Kepler-138 d 

Kepler-138 c and Kepler-138 d are two known exoplanets that orbit around the star Kepler-138. These planets were discovered by NASA’s Kepler spacecraft in 2013.  

Kepler-138 c is a very dense planet, with a mass of about five times that of Earth and a radius of only about 60% that of Earth. Kepler-138 d, on the other hand, is a bit less dense, with a mass of about six times that of Earth and a radius of about 70% that of Earth. 

Despite their similarities in size, Kepler-138 c and Kepler-138 d have very different conditions on their surfaces. Kepler-138 c is located closer to its host star and has an orbital period of only about 13 days.  

Because of its proximity to the star, the planet is thought to be tidally locked, meaning that one side of the planet always faces the star. This causes extreme temperature differences between the day and night sides of the planet. 

Kepler-138 d, on the other hand, has a longer orbital period of about 23.6 days and is located farther from the star. This makes its temperature more moderate and potentially more habitable.  

However, the planet’s high mass and dense composition suggest that it may not have a surface that is conducive to life as we know it. Nevertheless, the study of exoplanets like Kepler-138 c and Kepler-138 d is essential in our understanding of the diversity and characteristics of planets beyond our solar system. 

The exact composition of exoplanets like Kepler-138 c and Kepler-138 d is challenging to determine with certainty, and their water content remains uncertain.  

However, based on their classification as sub-Neptune exoplanets and the understanding of exoplanetary composition, it is believed that they may contain significant amounts of gas, including hydrogen and helium. 

The presence of water vapour or other volatile compounds in the atmospheres of such exoplanets is possible, but it depends on a variety of factors, including their formation history, distance from their host star, and atmospheric conditions. 

To determine the precise composition of these exoplanets, more detailed observations and studies would be required, possibly using advanced telescopes and spectroscopic techniques. As of now, while water vapour is a possibility, it’s not confirmed, and further research is needed to provide a definitive answer regarding their water content. 

Now, you might be wondering how we even know about these awe-inspiring planets.  

Well, it’s all thanks to NASA’s Kepler Space Telescope, which has played a pivotal role in uncovering countless exoplanets and revolutionizing our understanding of the cosmos.  

Without Kepler’s watchful eye, we might still be questioning the existence of these celestial marvels.
