The research focuses on a relatively new topic - the programming of biological life in planets orbiting red dwarfs * To verify the hypothesis, the James Webb Space Telescope, and the Israeli Ultrasat Space Telescope when they are launched, will be directed to the planets discovered by Vandel and his colleagues

"If rocky planets exist around white dwarfs, we should be able to detect signs of life on them in the coming years," said co-author Lisa Keltenger, associate professor of astronomy in the College of Arts and Sciences and director of the Carl Sagan Institute.
This image, taken by the SPHERE instrument on ESO's Very Large Telescope, shows the star TYC 8998-760-1 accompanied by two giant exoplanets, TYC 8998-760-1b and TYC 8998-760-1c. This is the first time that astronomers have directly observed more than one planet orbiting a Sun-like star. Both planets are visible as two bright spots in the center of the image (TYC 8998-760-1b) and lower right (TYC 8998-760-1c), indicated by arrows. Other bright spots, which are background stars, are also visible in the image. By taking different images at different times, the team was able to differentiate between the planets and the background stars. The image was taken by blocking the light from the young Sun-like star (top left of center) using a coronagraph, which allows the detection of fainter planets. The light and dark rings that you see on the image of the star are optical devices. Credit: ESO/Bohn et al

In our solar system, the ice giants Rahab (Neptune) and Oron (Uranus), their density is very less compared to that of the rocky planets Venus (Venus) and Earth. However, astrophysicists on NASA's TESS mission have now found an extrasolar planet, TOI-849b, that appears to be 40 times more massive than Earth, while having the same density as Earth. The figure depicts the planet UCF-1.01. As TOI-849b, this planet also orbits close to its sun and is a kind of “hot star.” Credit: NASA/JPL-Caltech
