NASA's James Webb Space telescope may be used to identify planets with oxygen

India Today  

Researchers in a recent study have found out how to use NASA's James Webb Space Telescope for quickly identifying nearby planets that could help in researchers search for life and search of the worlds that are uninhabitable due to vaporization of oceans. In a recent study, scientists have found that oxygen molecules collide to produce a strong signal and according to scientists, Webb can detect the signal present in the atmosphere of exoplanets. "This oxygen signal is known since the early 80's from Earth's atmospheric studies, but has never been studied for exoplanet research," added Fauchez. If Webb points to a planet and detects this 6.4-micrometer signal with relative ease, this would mean that the planet has a very dense oxygen atmosphere and maybe uninhabitable," said another researcher Ravi Kopparapu. For a desiccated exoplanet with an oxygen atmosphere 22 times the pressure of Earth's, the signal could be detected up to about 82 light-years away.

Astronomers finally detect a rocky planet with an atmosphere

The Hindu  

Astronomers have searched for years for rocky planets beyond our solar system with an atmosphere - a trait considered essential for any possibility of harbouring life. Researchers said on Wednesday the planet is a "super-Earth" - a rocky world significantly larger than our planet but smaller than Neptune - and it orbits perilously close to a star dimmer and slightly …

James Webb Telescope discovers super-Earth outside the Solar System

India Today  

The James Webb Telescope has delivered exactly what it was intended for. The world's most powerful observatory has detected atmospheric gases on a planet outside the Solar System, which has a rocky surface like Earth. James Webb Telescope cannot capture a direct image of 55 Cancri e. Nasa said that the planet orbits so close to its star that its …

Scientists may detect signs of extraterrestrial life in 5 to 10 years: Study

Hindustan Times  

Research shows that a new telescope could detect a potential signature of life on other planets in as little as 60 hours. "What really surprised me about the results is that we may realistically find signs of life on other planets in the next 5 to 10 years," said Caprice Phillips, a graduate student at The Ohio State University, who …

Daily Mail  

Astronomers have found at least 45 planets orbiting distant stars that possess Earth-like qualities including a similar atmosphere and life sustaining liquid water. Only 17 of the 55 planets in the catalogue met the criteria defined by the Swedish researchers for being 'Earth-like' but the team found another 28 planets on the wider exoplanet list that also met the criteria …

Scientists cannot go, visit other planets to find signs of life and can use this telescope to do so. In a recent study, scientists have found that oxygen molecules collide to produce a strong signal and according to scientists, Webb can detect the signal present in the atmosphere of exoplanets. When starlight passes through the atmosphere of exoplanet’s, oxygen generally …

New way of detecting oxygen on exoplanets could help find life

CNN  

CNN — The search for oxygen on other planets outside of our solar system, called exoplanets, is thought to be an aid in the search for life outside of Earth. The scientists believe their new method could speed up the quest for life by making it easier to tell if individual exoplanets could host life on their surfaces by peeking …

The Hindu  

The recent announcement at the American Astronomical Society meeting in California dramatically increases the possibility of finding Earth-sized extra-solar planets, or exoplanets, and in particular, those that are in a habitable ‘Goldilocks’ zone — neither too close nor too far from a star, so liquid water might be present on the surface. One study looked at the number of habitable …
