Many of us remember those school-room models of our Solar System, with tiny wooden planets rotating at the ends of their wires around a bright-orange painted sun. But how accurate is the model? Do the planets really align in a plane, or do their orbits crisscross around the sun at different angles? It turns out the toy isn’t too far off, at least in this one aspect.
L 98-59: a Benchmark System of Small Planets for Future Atmospheric Characterization -
Representation of the cosmic shoreline (Zahnle & Catling 2017), shown as a solid line. Additional dashed and dotted lines assume XUV flux 16 and 256 times higher than solar, respectively. Solar system bodies are shown as red circles, and exoplanets as small blue dots. The L 98- 59 and TRAPPIST-1 planets are indicated by green triangle and cyan squares, respectively.
Herein, we use simulated transmission spectroscopy to evaluate the detectability of spectral features with HST and JWST assuming diverse atmospheric scenarios (e.g., atmospheres dominated by H2, H2O, CO2, or O2). We find that H2O and CH4 present in a low mean-molecular weight atmosphere could be detected with HST in 1 transit for the two outermost planets, while H2O in a clear steam atmosphere could be detected in 6 transits or fewer with HST for all three planets.
Planetwatch Announces The Listing Of The PLANETS Token On Bitfinex Exchange
ST. GENIS-POUILLY, France , June 3, 2021 /PRNewswire/ -- Planetwatch, a French start-up which decentralizes and incentivizes environmental monitoring, announced that its utility token, PLANETS, will be listed on Bitfinex. PLANETS are the first Algorand Standard Asset (barring stablecoins) to be supported on a major international exchange.
Claudio Parrinello , PlanetWatch's CEO said: "This is a major milestone for PlanetWatch. Less than 18 months after company creation, and despite the COVID-19 pandemic, we have managed to demonstrate that our Smart City as a Service solution, based on community sensor deployment and crowdsourced air quality data, can deliver business-grade data feeds in a fast and cost-effective way."
Going to other planets is a moral duty, it's just a matter of making it safe
The author proposes a 10-phase, 500-year programme, to re-engineer the human genome so humans can tolerate the extreme environments of space, with the ultimate goal of achieving human settlement on other planets, perhaps even beyond our solar system.
It certainly sounds like science fiction, but for the vast part it's definitely not. Mason is a geneticist and computational biologist who has been a principal investigator and co-investigator on no less than seven NASA missions.
NASA will head to Venus for first time in roughly 30 years
NASA had a surprise in store for planetary scientists today: During a "State of NASA" briefing, the agency announced that roiling, toxic Venus will be the target of the next two missions in its highly competitive Discovery program.
"These two sister missions, both aimed to understand how Venus became an inferno-like world capable of melting lead at the surface—they will offer the entire science community the chance to investigate a planet we haven't been to in more than 30 years," NASA Administrator Bill Nelson said during the briefing. "We hope these missions will help further our understanding of how Earth evolved and why it's currently habitable, when other [rocky planets] in our solar system are not."
Planets align for Perth couple's Space Music collaboration | Community News
BEING married to astrophysicist and planetary geologist Dr Antony Brian is a match made in heaven for Australian Baroque artistic director Helen Kruger and her orchestra's multi-sensory project Space Music: Harmony of the Spheres.
"We worked together on the concepts we had for each section — the planets, moon, deep space, etc. — and paired these with music that we felt most accurately depicted it," Kruger said.
"We hope that the combinations we have come up with leave the audience with a feeling of total awe."
Is there a snowy season on other planets? | Latest Headlines | mooresvilletribune.com
Ever wonder how snow works elsewhere in the solar system? Turns out, the fluffy stuff takes on different forms than what we're used to on Earth.
No Man's Sky's Total Number of Planets Explained | Game Rant
Procedural generation of the world is another thing No Man's Sky shares with Minecraft. However, unlike Minecraft 's wholly random individual worlds , Hello Games' simulated universe actually has a pretty good picture of how many planets there are in No Man's Sky , and it's a staggering amount.
When No Man's Sky was first made public, Hello Games explained that while the game was technically multiplayer, odds were good that players could go through the whole game without ever running into each other just because of its massive scale. Looking at the numbers proves that Hello Games wasn't joking.
