The densest alien planet, 13 times larger than Jupiter, has been discovered by an international group of researchers led by Professor Abhijit Chakraborty of the Physical Research Laboratory (PRL) in Ahmedabad.
Scientists have discovered a Saturn-like exoplanet using a radio telescope for the first time. The detected planet is known as TVLM 513b. This particular planet has a similar mass to Saturn and an orbit analogous that is pretty similar to Mercury.
K2-18b, which is eight times the mass of Earth, is now the only exoplanet known to have both water and temperatures that could be potentially habitable, according to the study published in the journal Nature Astronomy.
Gravitational forces between all particles were calculated and used to update the positions, velocities and accelerations in the computer models of the planet and its ring system.
Located 21 light years away from us, this planet, dubbed HD219134 b, has a mass almost five times that of Earth, which is considered a so-called "super-Earth".
If a planet crosses in front of its parent star, then the observed brightness of the star drops by a small amount. The Kepler Space Telescope detected many exoplanets using this method.
"This would be the first case of detecting a moon outside our solar system," said David Kipping, an assistant professor of astronomy at Columbia University.
The Transiting Exoplanet Survey Satellite (TESS) sent the images that were captured from its initial science orbit. It will spend 2 years monitoring 26 such sectors for 27 days each.
The exoplanet 'Wolf 503b' is in the Virgo constellation and it orbits its star every six days and is thus very close to it, about 10 times closer than Mercury is to the Sun.
Data from the exoplanet-hunting Kepler Space Telescope and the Gaia mission indicates that many of the known planets may contain as much as 50 per cent water.
Scientists have developed a new low-cost technology that allows telescopes on Earth to observe exoplanets with greater precision.
New Delhi: An exoplanet is a planet outside the Solar System. For centuries philosophers and scientists supposed that extrasolar planets existed, but there was no way of detecting them. The first confirmed detection of exoplanet
