koena57jim, w Galle: Happy Face Crater on Mars

Mars has quite literally put on a happy face. The Martian crater Galle is famous for internal markings that resemble a smiling, winking face. These features were first noticed in images taken by the Viking Orbiter in the 1970s. Later, the Mars Global Surveyor (MGS), which orbited Mars from 1996 to 2006, captured the well-known image of what is now called the Happy Face Crater. This crater and its iconic appearance were formed purely by chance billions of years ago, when a city-sized asteroid struck the Martian surface. Impact craters are common on all rocky planets and moons in our Solar System, with the Moon and Mercury showing the highest numbers. Earth and Venus would display many more craters as well, if not for the effects of weathering, erosion, and geological activity. transunion credit freeze

Moderate sexual activity is a form of low-to-moderate intensity aerobic exercise. Try our AI sex doll will give you a stimulated sexual feeling and experience!

metallic_substance, w Red Spider Planetary Nebula from Webb

Beautiful. Also it’s red and it looks a lot like a spider, so 10/10 on the naming

sbeak, w Red Spider Planetary Nebula from Webb

JWST images look so cool!!!

CombatWombatEsq, w For 21 years, enthusiasts used their home computers to search for ET. UC Berkeley scientists are homing in on 100 signals they found.

Go Bears!

I ran SETI@home many years ago. You had to have a screensaver anyway, and I seem to recall that the screensaver portion looked super cool and science-y, so it was trendy even if you weren’t particularly enthusiastic about the actual project.

SpaceNoodle, w Largest galaxy survey yet confirms that the Universe is not clumpy enough

So … we don’t live in Clumpy Space?

supersquirrel, w Astronomers map magnetic superhighways in colliding galaxies

Yeah that is how it goes, you add one lane and then another and the EM traffic just keeps growing to match it.

Onomatopoeia, w Artemis I: Flight Day 13

Amazing what 70k clicks looks like.

Nastybutler, w Scientists discover potentially habitable planet roughly 146 light-years from Earth, 4 times closer than the next best planet in a habitable zone; surface temperature may be below -94F degrees

Please tell me they’ve named it Hoth

@Innerworld
Is it celsius or farenheit ?

Innerworld,

-94F, sorry

notfromhere,

First one and then the other.

How the is -94 degrees in any way habitable?

Pistcow,

Antarctica gets to -132?

Sanctus,
@Sanctus@anarchist.nexus avatar

Yeah and its not really habitable by humans. Its hard to just be there on Earth where there is oxygen.

Beacon, (edited )

Habitability in this usage means "a place where humans can live, either with or without technological assistance". In terms of temperature, this means the range of temperatures where machinery can reliably function. Of the temperatures found in the universe, this machinery-functionable range is actually extremely narrow

plantfanatic,

Same way mars is.

cogitase,

There’s not really any data other than a rough distance from its star. The atmosphere could be thick enough and with the right combination of greenhouse gases that the temperature at the equator is 23°C year round. We do know that it’s only receiving ~30% of the energy from its star as earth does from the sun, which is what they’re basing the low temperature estimates on.

The article itself also says -70 which, still very cold, is much better.

And it’s not like once we have the technology needed to travel 146 light years that we couldn’t do something insane like deploy mirror-film solar cells or something to capture extra heat in orbit around the planet and warm the entire planet and terraform it for our usage.

@Sanctus@anarchist.nexus avatar

Once? I dont think any if that is close or even gauranteed.

qupada,

-70°C is -94°F

dissentiate, w Polar weather on Jupiter and Saturn hints at the planets’ interior details

All my mind saw was pizza when I saw that image.

wegan64hardy, w Orion's Treasures over Snowy Mountains

Rising over a frozen valley in the Tatra Mountains, the night sky is dominated by the familiar stars and nebulas of Orion. This striking wide-field photograph, taken last month in southern Poland’s highest mountain range, captures both the rugged beauty of Earth and the structure of our galaxy. Above the snowy peaks, Orion’s bright belt stars anchor a region of glowing interstellar clouds, with the Great Orion Nebula—a vast stellar nursery visible to the naked eye Official Website
