24 planets that are warmer, wetter, and better for life than Earth
Where to look? Where to look?
Researchers examined data from terrestrial exoplanets orbiting in the habitable zone around their stars, where temperatures allow liquid water to pool on their surface. Just a small percentage of the 4,500 exoplanets now known to orbit other stars are known to have conditions relatively friendly to life.
“Most important from the perspective of an observer searching for extrasolar life is that such a search might be executed most effectively with a focus on superhabitable planets instead of Earth-like planets. We argue that there could be regions of astrophysical parameter space of star-planet systems that could allow for planets to be even better for life than our Earth,” researchers describe in an article published in the journal Astrobiology.
Each of the planetary systems examined in this new study sit more than 100 light years from our family of planets.
It took nearly four billion years for complex lifeforms to develop, suggesting that longer-lived stars may be more likely to host planets awash in life. The Sun, and other G-type stars like it, live for about 10 billion years. This study also examined planets abound cooler, less-massive K-type stars, which exist for between 20 and 70 billion years, allowing plenty of time to life to develop.
However, extremely old planets cool all the way through to their core, reducing or eliminating the planetary magnetic field protecting those worlds from harmful radiation. This study suggests planets between five and eight billion years old may be likely worlds to target in the search for life.
Other characteristics of exoplanets affecting the possible development of life include the mass and size of a chosen world. This new study suggests exoplanets 10 percent larger than the Earth would develop more land area than our own world. A planet 50 percent more massive would hold onto its inner heat longer than Earth, retaining its magnetic field and atmosphere for significantly more time than our home world. The video below shows an interview with Dr. Natalie Hinkel of the Southwest Research Institute, discussing how phosphorous can be used to find exoplanets likely to have developed life.
Temperatures are also a critical factor when looking for life where life may have developed. Exoplanets averaging 20 Celsius (68 Fahrenheit) — slightly warmer than Earth — were found to be wetter, more humid, and even friendlier to life than the world we call home.
Over billions of years, the habitability of Earth has fluctuated over time. Mass extinction events were triggered, from time to time, by asteroid impacts, and the (possibly) even nearby supernova explosions.
An ideal world, researchers speculate, will balance conditions toward great biodiversity, with occasional struggles for survival to drive natural selection.
“However, not every superhabitable planet may produce intelligent life because these variations might have either been too small for life to advance toward higher complexity or too large for life to keep up and instead become extinct,” researchers speculate.

Apple will replace AirPods Pro for free with faulty noise cancellation, static or crackling


Today, exactly one year after Apple first launched the AirPods Pro — and thus the same day the very first AirPods Pro owners will see their one-year warranties expire — Apple has launched a repair program that offers free repairs or replacements for another whole year if your AirPods Pro experience issues with noise cancellation or static.
Specifically, Apple will fix:
Crackling or static sounds that increase in loud environments, with exercise or while talking on the phone
Active Noise Cancellation not working as expected, such as a loss of bass sound, or an increase in background sounds, such as street or airplane noise
Apple says only a “small percentage of AirPods Pro” are affected by the issues, but it apparently wasn’t just an early batch — Apple says affected units were manufactured “before October 2020,” meaning every AirPods Pro ever made might be eligible. That’s quite a recall if so. Apple says it will repair faulty AirPods Pro for two years after you first buy them.
We’ve heard complaints about degraded noise cancellation before, and at least one Verge editor has replaced their AirPods Pro under warranty. It’s nice to hear that Apple isn’t just cutting buyers off as soon as that warranty expires.
