Not all stars are like the sun, so not all planetary systems can be studied with the same expectations. New research from a University of Washington-led team of astronomers gives updated climate models for the seven planets around the star TRAPPIST-1. The work also could help astronomers more effect...
TRAPPIST-1 is a system of seven Earth-sized worlds orbiting an ultra-cool dwarf star about 120 light-years away. The star, and hence its system of planets, is thought to be between five-to-ten billion years old, up to twice as old as our own solar system. For scientists seeking evidence for life els...
New Spectrograph on Subaru Telescope Shows “Earth-Like” TRAPPIST-1 Planetary Orbits Not Misaligned
(scitechdaily.com)
Astronomers using the Subaru Telescope have determined that the Earth-like planets of the TRAPPIST-1 system are not significantly misaligned with the rotation of the star. This is an important result for understanding the evolution of planetary systems around very low-mass stars in general, and in p...
Precise measurements reveal that the exoplanets have remarkably similar densities, which provides clues about their composition. The red dwarf star PIST-1 is home to the largest group of roughly Earth-size planets ever found in a single stellar system. Located about 40 light-years away, these seven ...
Astronomers Uncover New Details About the Remarkable Seven Rocky Planets of TRAPPIST-1
(scitechdaily.com)
Precise measurements reveal that the exoplanets of the system discovered by ULiège researchers have remarkably similar densities, which provides new clues about their compositions. A new international study led by astrophysicist Eric Agol from the University of Washington and involving many scientis...
Using theory and experiments, researchers show how apples get their distinct cusp-like features. Apples are among the oldest and most recognizable fruits in the world. But have you ever really considered an apple’s shape? Apples are relatively spherical except for that characteristic dimple at the t...
TRAPPIST-1’s seven planets likely formed sequentially near the snow line and migrated inward, producing the flattest known planetary system with just 0.072° inclination. The planets of the solar system all orbit the Sun more-or-less in a plane. Compared to the Earth’s orbit, which defines the ...
Orbital Harmony of TRAPPIST-1 Planets Could Survive Only Limited Early Bombardment
(scitechdaily.com)
Fragile orbits of seven exoplanets limit late arrival of water. Seven Earth-sized planets orbit the star TRAPPIST-1 in near-perfect harmony, and U.S. and European researchers have used that harmony to determine how much physical abuse the planets could have withstood in their infancy. “After rocky p...
During its first operating cycle, the James Webb Space Telescope will set its sights on the TRAPPIST-1 system, an incredible collection of seven rocky exoplanets 41 light-years away from Earth. Astrobiologists like Dr. Giada Arney from the NASA Goddard Space Flight Center are excited about this syst...
One in three young people say their mental health and wellbeing improved during COVID-19 lockdown measures, with potential contributing factors including feeling less lonely, avoiding bullying, and getting more sleep and exercise, according to researchers at the universities of Cambridge and Oxford....
Happier and Improved Cognition: Study Finds New Benefits of Regular Activity Routines
(scitechdaily.com)
A study finds that older adults with regular activity routines perform better on cognitive tests and are typically happier. According to a recent study performed by University of Pittsburgh researchers, older adults who regularly get up early and stay active throughout the day are happier and score ...
A recent study in the Journal of the American Heart Association suggests that the perceptions of teens, particularly Black youth, about their lives may influence their cardiometabolic health risk in adulthood. Teens with higher levels of optimism, happiness, self-esteem, belongingness, and feeling l...
Researchers from the University of Pennsylvania and Princeton University have found a consistent correlation between higher incomes and increased happiness for the majority of people, but a surprising trend of unhappiness among a minority despite rising incomes. This discovery has reconciled previou...
Mapping Happiness Across the Human Lifespan An analysis of more than 400 samples sheds light on the progression of subjective well-being throughout a person’s life. When do people reach their peak happiness? This seemingly simple question has been studied extensively over the past decades, but...
Hobbies Boost Mental Health and Wellbeing in Seniors A hobby is associated with reduced depressive symptoms and increased happiness, self-rated health, and life satisfaction in individuals aged 65 and above. This observation is consistent across 16 nations spanning three continents, according to a s...
A commonly held belief is that pets contribute positively to individual well-being. However, recent research from Michigan State University indicates that while pet owners acknowledge the benefits pets bring to their lives, there wasn’t a consistent link between owning pets and improved well-b...
Many Indigenous peoples and local communities around the world are leading very satisfying lives despite having very little money according to new research from the Institute of Environmental Science and Technology at the Universitat Autònoma de Barcelona (ICTA-UAB). The study reveals that several c...
A groundbreaking study has shown that while we can learn how to be happy, lasting benefits are only achieved through consistent practice. The team behind the University of Bristol’s ‘Science of Happiness’ course had already discovered that teaching students the latest scientific studies on happiness...
Smiling for just a split second makes people more likely to see happiness in expressionless faces, new University of Essex research has revealed. The study led by Dr Sebastian Korb, from the Department of Psychology, shows that even a brief weak grin makes faces appear more joyful. The pioneering ex...
Finland is consistently ranked as the happiest country in the world. The basis for this is the annual World Happiness Report, which is based on a simple question about happiness asked to people around the world. However, a new study led by Lund University in Sweden suggests that it makes people thin...
