Exoplanets: any planet must have a magnetic field to avoid radiation from stars

New York. Scientists have been claiming that planets outside of the solar system, also known as exoplanets, may have a life expectancy, based on recent studies and on the information gathered from the universe. Scientists had predicted such a possibility based on the distance from the exoplanet to its star and other calculations.

It was speculated that due to the proper distance, there could exist water and a habitable environment, but now a new study claimed that all exoplanets that are also located at a reasonable distance from their stars, all of them have a life expectancy. It can be difficult.

Researchers at New York University in the US noted that these exoplanets are very sensitive to the flare emanating from their stars. They stated that unless an exoplanet has a magnetic field and atmospheric pressure, habitable conditions cannot exist there. The study, published in the Royal Astronomical Society Letters, has revealed that the flare emanating from the stars can severely affect the exoplanet. Only this can save the planet’s magnetic field and atmospheric pressure.

Dimitra Atri of New York University said that as soon as we detect an exoplanet and find the possibility of life in it, first of all, we need to find out the magnetic field and atmospheric pressure. He said that scientists in this field need to develop more understanding. By studying the magnetic field, atmospheric pressure, distance to the stars and other factors in the exoplanet closely, it can be ascertained whether there is a possibility of life.

ISRO sets RISAT-2BR1’s antenna

ISRO has shared a video on social media showing the success of its recently launched mission. In this video, the radial rib antenna of the recently launched RISAT-2 BR1 is set in space. Share this video on Twitter, users are very much like it. ISRO has shot this video with its satellite’s onboard camera. The video shows the radial rib antenna mounted on the RISAT-2BR1, which was previously closed like an umbrella, but gradually expands completely after the satellite reaches its orbit.

In the video, this umbrella of the satellite is seen gradually opening up completely. This video is of the successful deployment of this antenna in the orbit on December 12 at 2 pm. This 3.6-meter antenna was folded and placed in the spacecraft at the time of launching. Which was later opened.
