Exciting space-discovery alert!

Gliese 12 b is an Earth-size planet orbiting in the temperate zone around a nearby, stable red dwarf star. It's a Rosetta Stone world that will tell us a lot about how many superficially earthlike planets actually have the right conditions for life.

Are we rare? Are we common? Let's find out.

Many stories about newfound planet Gliese 12b (including the news release from the Royal Astronomical Society, sad to say) are full of errors.

We have NO idea yet what conditions are like there. That's what makes it so exciting! This is the kind of discovery that will provide big answers.

If you're the kind of person who likes to go deep, I got you.

The full research paper is freely available online, providing the technical details of how astronomers found the Earth-size planet Gliese 12b, and what we really do (and do not) know about it.

What a great photo, though - perfect timing! But I suppose that conjunction happens pretty regularly, on an astronomical scale. 🤔

My office at work currently has 4 women and 1 man.

I have been the “only” woman in an office full of men so many times - this is the first time it’s been reversed! And I’m having so much fun! (Sorry, Thomas, for all of the silliness!)

sysop408,
@sysop408@sfba.social avatar

@absolutspacegrl did it take any getting used to? For various reasons, I've repeatedly been the only man in places run by women.

I'm so used to it that when I'm in a room where the tables are turned and it's almost all men, I become hyper-self aware like I'm watching myself from out of body instead of just being there.

My wife has had similar experiences, but with ethnicity. If she's the only white person in a room, it feels normal. If everyone's white, it feels weird to her.

I'm sure you don't need any help getting comfortable in a room full of men, but based on what you've seen, what could your average guy do if he finds himself in a chance social situation where there's exactly one woman?

absolutspacegrl,
@absolutspacegrl@mastodon.social avatar

@sysop408 Great question! Yes & no it- it was gradually introduced. 1st, it was me & 2 other men…1 of the women was out for maternity leave. She came back, so 50/50. Then one of the men took another job, but he wasn’t replaced immediately. Then he was, w another woman, then we got an intern who’s a woman just this week.

When I notice it I think about how unusual it is, but we get along & are friendly, & I realize that’s not always the norm. It’s different on 2 levels but welcome!

A potentially habitable exoplanet that is roughly similar in size to Earth has been found in a system located 40 light-years away, according to a new study.

The planet is about the size of Venus, so slightly smaller than Earth, and may be temperate enough to support life, the researchers said.

Dubbed Gliese 12 b, the planet takes 12.8 days to orbit a star that is 27% of the sun’s size. It’s not yet known whether the exoplanet has an atmosphere

Another ~25m and will be out of t̵h̵e̵ ̵w̵o̵o̵d̵s̵ the regolith ripple field and in the mostly flat part of the Neretva Vallis riverbed.

Tosol's ~17m drive brought the rover right where those ripples start. The dark area is where will be hidden from our remote prying eyes.

@65dBnoise in awe at how much the POV has changed with just ~100m traverse on the last few sols, amazing landscape! Now don't get stuck on that sand

@sharponlooker
It was about time after all those months in the middle of rocky nowhere 😜 The loose regolith ahead seems rather shallow, with bedrock showing here and there (IANAG™), and the rover drivers did a pretty good job bringing it down here on a steady and safe pace. Two more drives and that's it, I think.

While the solar panel of the may still be visible from the rover at its present location on Sol 1159, it will soon disappear when clears the ripples it's facing on its way northwest to Bright Angel.

I'm still working on some updates for it, and as such it's still isn't perfect. But if you are interested in a simple Newtonian arcade space shooter, my game Flank Speed is available on Steam. Kind of a modern take on the classic game "Space War". With multiplayer in the works.

In the annals of we-are-all-connected....

Each year, on average 27.7 million tons of Saharan dust, carried on wind currents across the Atlantic, drop into Amazonia, bringing vital phosphorus from the Bodélé Depression in Chad, an ancient lake bed. Amazonia's plant life needs this transoceanic fertilization. https://www.nasa.gov/centers-and-facilities/goddard/nasa-satellite-reveals-how-much-saharan-dust-feeds-amazons-plants/

We have the first science images from the ESA’s Euclid telescope and they are STUNNING. Euclid can take detailed photos with a wide field of view. Here’s a breakdown of what you’re looking at and why it’s important.

UC Santa Cruz researchers contributed to new studies out this week that enhance our understanding of exoplanets.

The first catalogs 126 exoplanets discovered detailing diverse planet types.

A second set, investigates "puffy" exoplanets like WASP-107b attributing their puffiness to tidal heating.

This research broadens our knowledge of exoplanet characteristics and formation.

I love serendipitous art!

ESA's Euclid space telescope is designed to map dark matter and dark energy across the universe. But as it is getting started, Euclid is also sending back gorgeous cosmic snapshots.

https://www.esa.int/Science_Exploration/Space_Science/Euclid/ESA_s_Euclid_celebrates_first_science_with_sparkling_cosmic_views

Euclid’s image of galaxy cluster Abell 2390 reveals more than 50 000 galaxies and shows a beautiful display of gravitational lensing, depicting giant curved arcs on the sky – some of which are actually multiple views of the same distant object. Euclid will use lensing (where the light travelling to us from distant galaxies is bent and distorted by gravity) as a key technique for exploring the dark Universe, indirectly measuring the amount and distribution of dark matter both in galaxy clusters and elsewhere. Euclid scientists are also studying how the masses and numbers of galaxy clusters on the sky have changed over time, revealing more about the history and evolution of the Universe.
Here, Euclid captures galaxies evolving and merging ‘in action’ in the Dorado galaxy group, with beautiful tidal tails and shells seen as a result of ongoing interactions. Scientists are using this dataset to study how galaxies evolve, to improve our models of cosmic history and understand how galaxies form within halos of dark matter. This image showcases Euclid’s versatility: a wide array of galaxies is visible here, from very bright to very faint. Thanks to Euclid’s unique combination of large field-of-view, remarkable depth, and high spatial resolution, it can capture tiny (star clusters), wider (galaxy cores) and extended (tidal tails) features all in one frame. Scientists are also seeking distant individual clusters of stars known as globular clusters to trace their galactic history and dynamics.
In this image Euclid showcases NGC 6744, an archetype of the kind of galaxy currently forming most of the stars in the local Universe. Euclid’s large field-of-view covers the entire galaxy, capturing not only spiral structure on larger scales but also exquisite detail on small spatial scales. This includes feather-like lanes of dust emerging as ‘spurs’ from the spiral arms, shown here with incredible clarity. Scientists are using this dataset to understand how dust and gas are linked to star formation; map how different star populations are distributed throughout galaxies and where stars are currently forming; and unravel the physics behind the structure of spiral galaxies, something that is still not fully understood after decades of study.

"When you look at the northern sky, you can follow the arm of the Big Dipper as it arcs around toward the bright star called Arcturus. Roughly in the middle of that arc, you'll find the Northern Crown constellation, which looks a bit like a smiley face. Sometime between now and September, if you look to the left-hand side of the Northern Crown, what will look like a new star will shine for five days or so."
