Researchers conducted a novel study on the runaway greenhouse effect, revealing how a critical threshold of water vapor can lead to catastrophic climate changes on Earth and other planets. The research reveals a significant cloud pattern that contributes to this irreversible climate change, providing insights into exoplanet climates and their potential to support life.

Their efforts paid off. They confirmed a third planet in the system and realized that they had found the key to unlocking the whole system because it was now clear that the three planets were in an orbital resonance. The outer-most planet takes 20.519 days to orbit, which is extremely close to 1.5 times the orbital period of the next planet with 13.673 days. This in turn is almost exactly 1.5 times the orbital period of the inner planet, with 9.114 days.A rare family of six exoplanets has been unlocked with the help of…

Fohlmeister, editedA groundbreaking study reveals that cool stars with strong magnetic fields produce powerful stellar winds, crucial information for assessing the habitability of exoplanetary systems.Employing state-of-the-art numerical simulations, a study led by scientists at the Leibniz Institute for Astrophysics Potsdam (AIP) has obtained the first systematic…

An international team of astronomers used the CHEOPS and TESS satellites to discover a system of six planets orbiting the star HD110067 in a unique harmonic resonance. This rare finding, involving a chain of 3:2 and 4:3 resonances, was initially challenging to decipher but was eventually solved, revealing the precise orbital periods of the planets. An international collaboration between astronomers using the CHEOPS and TESS space satellites, including NCCR PlanetS members from the University of Bern and the University of…

This artist’s concept shows the European Space Agency’s ARIEL spacecraft on its way to Lagrange Point 2 (L2) — a gravitationally stable, Sun-centric orbit — where it will be shielded from the Sun and have a clear view of the sky. Credit: ESA/STFC RAL Space/UCL/Europlanet-Science Office Ariel, ESA’s mission to identify the chemical elements in exoplanetary atmospheres, successfully passed the spacecraft preliminary design phase and now moves from the ‘drawing board’ to the construction phase. Today, the preliminary…

Penn State researchers have discovered an extraordinarily massive planet orbiting an ultracool dwarf star, challenging existing theories of planet and star formation. Named LHS 3154b, the planet’s mass is over 13 times that of Earth, while its host star, LHS 3154, has a mass significantly lower than the sun. Credit: SciTechDaily.com Researchers at Penn State have discovered an unusually massive planet, LHS 3154b, orbiting an ultracool dwarf star. This finding, contradicting current theories, prompts a reassessment of…

Scientists have discovered a unique star system, HD110067, where six planets orbit in a rhythmic gravitational lockstep, a rare phenomenon that could reveal new insights into planet formation and evolution. Study led by University of Chicago astronomer Rafael Luque may tell us about how planets form. Scientists have discovered a rare sight in a nearby star system: Six planets orbiting their central star in a rhythmic beat. The planets move in an orbital waltz that repeats itself so precisely it can be readily set to…

Astronomers using the James Webb Space Telescope have observed water and molecules essential for rocky planet formation in a highly irradiated area of the Lobster Nebula. This discovery, part of the XUE program, expands the known environments where rocky planets can form, challenging previous beliefs and providing new insights into exoplanet diversity. Astronomers find a range of molecules that are among the building blocks for rocky planets. Space is a harsh environment, but some areas are even harsher than others. A…

An artist’s illustration of the six newly discovered planets circling their star in resonance. Credit: Roger Thibaut (NCCR PlanetS) Researchers led by Rafael Luque discovered six planets in a rare gravitational resonance around a smaller, cooler star. This unique arrangement, stable since the system’s formation, was identified using data from NASA’s TESS and ESA’s CHEOPS, revealing insights into planetary evolution. The Discovery Six planets orbit their central star in a rhythmic beat, a rare case of an “in sync”…
