Life goes on on Snowball Earth, but beyond that, the cryogenic regime might be more forgiving on the surface biosphere than our own world...

Where in #space can #planets with #atmospheres be found? C. Cherubim et al. (2026) used #nearinfraredspectroscopy to characterize a #rocky #exoplanet orbiting its host star within the #habitablezone. Planet #LHS1140b exhibits #helium #absorption in its atmosphere, a feature the authors attribute to a helium-dominated #upperatmosphericlayer.

💁🏻‍♀️ TIL: 🪐🔭 For the first time, astronomers have detected an #atmosphere on a rocky #planet in the habitable zone of another #star.

The super-Earth LHS 1140 b, located 50 light years away, shows signs of a #helium dominated atmosphere escaping into #space. Researchers used the WINERED #spectrograph at Las Campanas Observatory to make the ground-based #discovery.

Through the heatwave haze, the hypocrisy of Australia’s fossil fuel policy shines bright

"The heatwave that blanketed much of Australia in early January was five times more likely to occur now than before human-caused global heating changed the climate." World Weather Attribution

"The focus in 2026 is increasingly likely to turn to the nation’s huge fossil fuel exports, an area where the government – which declares it is committed to trying to limit global heating to just 1.5C, a goal rapidly fading from view – remains blatantly hypocritical...Thermal coal expansions still get the greenlight."

A groundbreaking discovery! A Super-Earth, located just $20$ light-years away, has been confirmed to be orbiting within its star's Goldilocks Zone. This placement makes the existence of liquid water highly plausible. This is the moment science fiction turns into a potential fact.

The local meteorologist referred to today's weather as the "Goldilocks Zone." I described that as "#HabitableZone" on my #ClimateChangeWeatherWheel -- but I like the idea of #GoldilocksZone -- not too hot, not too cold. Treasuring the days where we're in the G-Zone.

A #Galactic Habitable Zone excludes stars too close to the galactic center. Our Sun is a nice distance away from the galactic center, about 28,000 light years. Keeping out of the way of the Galaxy’s spiral arms is another requirement of the Galactic #HabitableZone https://astrobiology.nasa.gov/news/galactic-habitable-zones/

#30DayChartChallenge Día 29: Extraterrestrial! 👽✨ ¡Planetas con su incertidumbre a cuestas! #UncertaintiesWeek #Astronomy

Volvemos al gráfico Radio vs Insolación (log-log, color=Temp) de exoplanetas (NASA Archive). Pero hoy añadimos una capa visual para la incertidumbre: el "halo" gris ⚪️ detrás de cada punto.

El tamaño del halo es proporcional al log(error) reportado para la Insolación. ¡Halos grandes = más incertidumbre en la energía que recibe ese planeta!

Es un recordatorio de que los datos astronómicos tienen errores y no todos los puntos son igual de "seguros". Interesante ver qué planetas en la zona habitable (verde) tienen más incertidumbre. (+ Venus/Tierra/Marte 💎).

#ClimateDiary for 8/14/2024 in #Maine. Temperatures are in the #HabitableZone, but #WildfireHaze made the "clear" sky hazy white. #AirQuality not the best, especially in #NorthernMaine.

So, usually this trail is not so silent, as it's an ATV trail in summer, and a snowmobile trail in the winter. But for some reason, I had it all to myself today! Days like that are few and far between, but it made for a truly #SilentSunday. Even the lawnmowers and weed whackers were silent! It was just birds and insects! And it wasn't too warm (low 80's) or humid. A true gem of a day!

Temperatures to challenge all-time highs in #California, #Nevada

Temperatures will not only rival records over the interior West through this weekend, but the heat will pose dangers for those outdoors for long periods and those taking to the roads for holiday travel.

By Alex Sosnowski, AccuWeather senior meteorologist

Published Jul 2, 2024 1:30 PM EDT | Updated Jul 4, 2024 1:42 PM EDT

"While the summertime is quite hot across the interior of the western United States in the valleys, basins and deserts, the heat will soon go above and beyond what is typical. AccuWeather meteorologists continue to warn of dangerous heat that will build through at least the first weekend of July over the interior #Southwest and into mid-July over the interior #West.

"This level of heat will not only challenge daily high-temperature records but will also make a run at some all-time record highs for the month of July and for any time of the year.

"'The worst heat will be over the #CentralValley of California, as well as the deserts of southeastern California, southwestern Arizona and southern Nevada,' Zehr explained, 'These places will see highs of 110 or more; the highest temperatures in Death Valley will be near 130 degrees.'"
