"Revolutionary Exoplanet Discoveries: Young Jupiter's Sibling and Eclipsing Cataclysmic Variable System Unveiled"

Astronomers using the W. M. Keck Observatory have successfully captured direct images of AF Lep b, one of the lowest-mass planets, using the astrometry technique. This marks the first time astrometry has been used to detect a giant planet orbiting a young Sun-like star. AF Lep b is approximately three times the mass of Jupiter and orbits a young star about 87.5 light-years away. This breakthrough could revolutionize the discovery of extrasolar planets that are challenging to detect due to their distance, mass, or orientation relative to Earth.

"Stunning Discovery: Young Planet Mirrors Jupiter's Features"

Astronomers have discovered a young exoplanet, AF Lep b, using the astrometry method, which involves measuring tiny changes in a star's position caused by the gravitational tugs of an orbiting planet. This is the first time astrometry has been used to find a giant planet orbiting a young star similar to the Sun. The team also used direct imaging to confirm the planet's existence and determine its mass, distance from its star, and orbital eccentricity. Further observations and studies of AF Lep b will be conducted using advanced telescopes like the James Webb Space Telescope.

'Jupiter's Younger Sibling' Marks Start of Exoplanet Discovery Era

Astronomers using the W. M. Keck Observatory in Hawaii have directly captured images of AF Lep b, one of the lowest-mass planets ever discovered. The planet is about three times the mass of Jupiter and orbits a young sun-like star about 87.5 light-years away. The discovery was made using a technique called astrometry, which measures the subtle movements of a host star over many years to help astronomers determine whether hard-to-see orbiting companions, including planets, are gravitationally tugging at it. This new method of combining direct imaging with astrometry could help astronomers find extrasolar planets that were hard to find before with other methods.
