NASA’s James Webb Space Telescope uncovers ‘boiling ocean’ exoplanet – could it harbour life?

[ad_1] In a groundbreaking discovery, NASA's James Webb Space Telescope (JWST) has revealed intriguing details about a distant exoplanet, sparking a debate among scientists about its potential habitability. The exoplanet, known as TOI-270 d, lies approximately 70 light-years away and boasts twice the radius of Earth.Observations from the James Webb Space Telescope exposed the presence of water vapour, methane, and carbon dioxide in the exoplanet's atmosphere, suggesting a composition consistent with a colossal water world. Researchers from the University of Cambridge propose that an entire surface ocean, potentially reaching temperatures exceeding 100 degrees Celsius, envelops TOI-270 d. However, they caution against envisioning this as an inviting seascape, emphasizing the extreme cond...

400 Earth-mass rogue planets in the Milky Way Galaxy? NASA explains

[ad_1] NASA reveals that the Milky Way Galaxy may contain over 400 Earth-mass rogue planets. These rogue planets drift in space and they do not orbit any star at all, which makes them special. It is speculated that these planets are hidden in the Milky Way Galaxy and NASA's Nancy Grace Roman Space Telescope could spot over 400 of these rogue planets. According to NASA's report, the unknown planets were from outside the galaxy, but drifted into it with some unknown mechanism. “We estimate that our galaxy is home to 20 times more rogue planets than stars – trillions of worlds wandering alone,” said David Bennett, a senior research scientist at NASA's Goddard Space Flight Center in Greenbelt, Maryland. About the rogue planet and upcoming missionSo far we know that planets outside the sol...

Largest ‘mirror’ in the Universe! Check out this unique exoplanet

[ad_1] Europe's Cheops Space Telescope has discovered a scorching hot exoplanet where metal clouds and rain drops of titanium are making it the most reflective planet ever seen outside our solar system. The planet is located 260 light years away from Earth which reflects 80 percent of the light from its host star.Astronomers believe that the exoplanet can match Venus' shininess and planet LTT9779 b which was found earlier in 2020 and orbits its star in just 19 hours. About the newly discovered exoplanetAccording to ESA. the exoplanet is the same in size as Neptune, making it the largest “mirror” in the Universe. Its exceptional reflectivity can be attributed to the presence of metallic clouds. These clouds consist mainly of silicate. The researchers believe the planet's size and tempera...

James Webb Space Telescope makes sensational discovery on coolest exoplanet TRAPPIST-1 c

[ad_1] Back in February 2017, researchers with the help of the Spitzer Space Telescope discovered a large batch of Earth-sized rocky exoplanets. Ever since then, researchers have been trying to study the atmosphere of TRAPPIST-1 c with the help of NASA's Jammes Webb Space Telescope.Recently, researchers were successfully able to study the atmosphere of the rocky exoplanet and stated that it is the coolest exoplanet with a dayside temperature of about 225 degrees Fahrenheit based on thermal emission. However, researchers at NASA are unsure about its atmosphere due to its very thin layer of carbon dioxide. They believe that if the planet's atmosphere exists at all, it is extremely thin. The finding represents a significant advancement to understand whether planets orbiting small red dwarf...

Earth-like exoplanet with volcanoes found by NASA’s TESS and Spitzer telescopes

[ad_1] Scientists using NASA's TESS (Transiting Exoplanet Survey Satellite) and Spitzer Space Telescope have made a remarkable discovery —an Earth sized exoplanet orbiting a star in a neighbouring galaxy. This finding provides the strongest evidence to date of active volcanoes existing beyond our solar system. The observations indicate that this rocky planet has a rugged surface and experiences frequent eruptions, resembling Jupiter's moon Io, which is the most volcanically active body in our solar system. While the volcanism on the exoplanet wasn't directly observed, scientists inferred its presence from the gravitational interaction with the larger of the two planets also orbiting the star. The gravitational pull of the larger planet may cause the newly identified exoplanet to flex a...

HISTORIC! NASA James Webb Telescope finds its FIRST Earth-sized exoplanet

[ad_1] NASA’s James Webb Space Telescope has confirmed its first exoplanet that is the size of the Earth. Know all about this new planet here. For the first time ever, NASA's James Webb Space Telescope has confirmed the discovery of its first planet outside our solar system. The planet found by the Webb telescope was classified as LHS 475 b, the planet which is almost exactly the same size as our planet, clocking in at 99 percent of Earth's diameter. NASA's Transiting Exoplanet Survey Satellite (TESS) hinted towards the existence of this newly found planet, which helped the team to choose this target for the James Webb Telescope. Planet LHS 475 b is relatively close. NASA says that it is 41 light-years away from Earth, in the constellation Octans."The fact that it is also a small, roc...

Is this the way Earth is going to die? Death of Exoplanet shows how

[ad_1] An exoplanet which is approaching its end could provide insight into how Earth will die. An exoplanet which is spiralling towards its end into a star could give scientists new insight into how Earth will die. The exoplanet in discussion is Kepler-1658b which was the first planet-candidate to be discovered by NASA's Kepler Space Telescope. According to NASA, Kepler-1658b is a gas giant exoplanet that orbits an F-type star called Kepler 1658. Now, scientists have made a recent discovery about the exoplanet which could spell Earth's future demise.In a recent study, scientists have observed that the exoplanet's orbit is decaying and it is likely to meet its end by colliding and falling into the star it orbits. This has given scientists a first glimpse into the last stage of existen...

Earth-like planets may not host aliens due to solar storms! Check mystery

[ad_1] Exoplanets, similar to Earth, which were earlier thought to be capable of nurturing alien life might actually be uninhabitable due to these dangerous solar storms. Scientists have been concerned about the mood-swings of the Sun this year. The Sun is entering the phase where it reaches the peak of solar activity in 2023 and as a result it has been blasting solar storms on a regular basis towards the Earth. While we have not seen a fearsome Carrington level event so far that damages power grids and more, the fear of a similar solar storm remains within the scientists as it can do an unthinkable amount of damage. But it turns out that planets outside the solar system which are also called exoplanets are suffering from som...

STRANGE! This exoplanet’s unique tilted orbit left astronomers baffled

[ad_1] Astronomers found this alien planet via its unique star wobbles as it moves through space. Know in detail here. For the first time, an exoplanet around a star in a binary star system has been portrayed in three dimensions. The strange fact is that the planet orbits its star at a different angle and scientists suggest that the misalignment could offer clues about how planets form in a binary system. The exoplanet named GJ 896Ab is located 20.3 light-years away from Earth, a space.com report mentioned.With the aid of archived optical observations from 1941 to 2017 and additional data covering 2006 to 2011 collected by the Very Long Baseline Array (VLBA), a network of 10 radio telescopes expanded across the United States,...
