I hope when muslims comment ‘being naked is not freedom’ on posts of women talking about being forced to wear the hijab and wanting to take it off, they realize how stupid they sound by implying visible hair is equal to full nudity. like even religious-wise, you just sound soooo dumb
And what's wrong with female nudity? Let's bring that back

Welcome to the Far Side of the Moon
A crescent Earth sets behind the Moon.
On April 6, 2026, the Artemis II astronauts flew around the Moon, observing the far side – which we never see on Earth thanks to tidal locking – with their own eyes and with cameras.

You know as an American born in the late 90s I’ve watched my country blow up foreigners on tv supposedly in the interest of national security since I was a toddler but quite frankly we live on a natural fortress of a continent with friendly nations to our north and south and have been attacked on our own soil literally two times in the past hundred years and we have military bases on every inhabited continent on earth. It’s never made sense to do these things for “national security”. It never will make sense unless you value the shareholders of weapons companies over the lives of children. And apparently a concerning amount of people do.
GUYS. THIS IS A REAL PHOTOGRAPH TAKEN BY A HUMAN. HOLY SHIT.
You see all those impact craters? We better hurry up and get rid of religion before our ticket gets punched
Planets need more water to support life than scientists previously thought
Unfortunately for science fiction fans, desert worlds outside our solar system are unlikely to host life, according to new research from University of Washington. Scientists show that an Earth-sized planet needs at least 20 to 50% of the water in Earth’s oceans to maintain a critical natural cycle that keeps water on the surface.
Scientists believe that there are billions of planets outside our solar system. More than 6,000 of these exoplanets are confirmed, but only some of them are candidates for life. The search for life has focused on planets in the “habitable zone,” a sweet spot that is neither too close nor too far from a central star. Planets in this zone are considered viable because they can maintain liquid surface water.
“When you are searching for life in the broad landscape of the universe with limited resources, you have to filter out some planets,” said lead author Haskelle White-Gianella, a UW doctoral student of Earth and space sciences.
Water, although essential, does not guarantee the existence of life. With this study, researchers worked to further narrow the search by investigating planets with just a small amount of water.
“We were interested in arid planets with very limited surface water inventory — far less than one Earth ocean. Many of these planets are in the habitable zone of their star, but we weren’t sure if they could actually be habitable,” White-Gianella said.
The team’s results, published April 13 in Planetary Science Journal, show that habitability hinges on the geologic carbon cycle — a water-driven process that exchanges carbon between the atmosphere and interior over millions of years, stabilizing surface temperatures.
Carbon dioxide, which comes from volcanoes in a natural system, accumulates in the atmosphere before falling back to Earth dissolved in rainwater. Rain erodes and chemically reacts with rocks on the Earth’s surface and runoff transports carbon to the ocean, where it sinks to the seafloor. Plate tectonics drives carbon-rich oceanic plates below continental land. Millions of years later, carbon resurfaces as mountains form.
If water levels drop too low for rainfall, carbon removal — from weathering — can’t keep up with emissions from volcanic eruptions and carbon dioxide levels in the atmosphere spike, trapping water. Rising temperatures evaporate the remaining surface water, initiating runaway warming that makes the planet too hot to support life.
“So that unfortunately makes these arid planets within habitable zones unlikely to be good candidates for life,” White-Gianella said.
Although scientists have instruments that can measure surface water, rocky exoplanets are difficult to observe directly. In this study, the researchers ran a series of complex simulations to better understand how water might behave in these desert worlds.
Previous efforts to model the carbon cycle focused on cooler, perhaps wetter planets. The models factored in evaporation from sunlight, but didn’t include other drivers, such as wind. White-Gianella adapted existing models to drier planets by refining evaporation and precipitation estimates.
“These sophisticated, mechanistic models of the carbon cycle have emerged from people trying to understand how Earth’s thermostat has worked — or hasn’t — to regulate temperature through time,” said senior author Joshua Krissanen-Totton, a UW assistant professor of Earth and space sciences.
However, the function of the geologic carbon cycle on arid planets was largely unexplored. The results show that even planets that form with surface water could lose it, transitioning from potentially habitable to uninhabitable due to carbon cycle disruption.
One such planet exists far closer to home: Venus. The planet of love is roughly the same size as Earth, likely formed around the same time and may have started with a similar amount of water.
Yet today, the surface of Venus rivals the temperature of a wood-fired pizza oven. Standing on the surface would feel like being crushed by 10 blue whales, White-Gianella said.
Many theories attempt to explain why Earth and Venus are so different. White-Gianella and Krissanen-Totton propose that Venus, being closer to the sun, may have formed with slightly less water than Earth, which imbalanced the geologic carbon cycle. As surface temperatures rose with atmospheric carbon dioxide levels, Venus lost its water — and any life it may have hosted.
Upcoming missions to Venus will attempt to understand what happened to the planet and whether it ever hosted life. The findings could also offer insight into planets much farther away.
“It’s very unlikely that we will land something on the surface of an exoplanet in our lifetime, but Venus — our nextdoor neighbor — is arguably the best exoplanet analog,” White-Gianella said.
The researchers hope that results from future missions will help validate the results of their modeling.
“This has implications for a lot of the potentially habitable real estate out there,” Krissanen-Totton said.

Have you considered smoking one (1) joint?
Scientists have discovered that a highly unusual giant planet—sometimes called "forbidden"—could have an atmosphere with fewer heavier eleme
The giant exoplanet TOI-5205 b, orbiting a small star, exhibits an atmosphere with unusually low metallicity—lower than both its host star and gas giants like Jupiter. Spectroscopic observations reveal a carbon-rich, oxygen-poor atmosphere with methane (CH4) and hydrogen sulfide (H2S), suggesting limited mixing between the planet’s interior and atmosphere.

My least favorite new politically correct term is "unhoused." Like you can just tell it was created to make liberals feel less icky when talking about homeless people.
I was homeless. I was homeless as a child and as an adult. That shit sucks believe it or not.
The uncertainty. The ever-present grimy feeling from lack of access to running water. Having nothing to your name. The shame you feel is asking your fellow man for the bare minimum. Just so much shame, man.
"Unhoused" is so clinical. A technical term. Sure, its not incorrect, but it doesn't properly convey the emotional and psychological impact homelessness has on you.
You say "house", I think of a structure.
You say "home", I think of stability.
The Earth formed from local building blocks
Planetary scientists have long debated where the material that formed our Earth comes from. Despite its location in the inner Solar System, they consider it likely that 6–40 per cent of this material must have come from the outer Solar System, i.e., beyond Jupiter.
For a long time, material from the outer Solar System was considered necessary to bring volatile components such as water to Earth. Accordingly, there must also have been an exchange of material between the outer and inner Solar Systems during the formation of the Earth. But is that really true?
“We were truly astonished”
Planetary scientists Paolo Sossi and Dan Bower, from ETH Zurich, compared existing data on the isotopic ratios of a wide range of meteorites, including those from Mars and the asteroid Vesta, with those of Earth. Isotopes are sibling atoms of the same element (same number of protons) that have a different mass (different number of neutrons).
The researchers analysed this data in a new way and arrived at a surprising conclusion: the material that makes up Earth originates entirely from the inner region of the Solar System.
Material from the outer Solar System, by contrast, is likely to account for less than two per cent of Earth’s mass, or even nothing at all. The corresponding study has just been published in the journal Nature Astronomy.
“Our calculations make it clear: the building material of the Earth originates from a single material reservoir,” says Sossi. His colleague Bower adds: “We were truly astonished to find that the Earth is composed entirely of material from the inner Solar System distinct from any combination of existing meteorites.”
For their study, the ETH researchers used existing data on ten different isotopic systems from meteorites, and analysed them using a specialised statistical method. Previous studies have mostly considered only two isotopic systems.
“Our studies are actually data science experiments,” says Sossi. ‘We carried out statistical calculations that are rarely used in geochemistry, even though they are a powerful tool.’
Isotope signature reveals origin
Isotopes in meteorites have long been used by researchers to determine the origin of celestial bodies, i.e. which part of the Solar System they come from. Historically, however, only the various isotopes of the element oxygen could be used to determine their provenance.
It was not until the early 2010s that an American researcher discovered that other isotopes, such as of chromium and titanium, could also be used for this purpose. This has enabled researchers to classify meteorites into two categories: non-carbonaceous ones, which form exclusively in the inner Solar System, and carbonaceous ones, which contain more water and carbon and originate in the outer Solar System.
The new analysis reveals that the Earth is composed entirely of non-carbonaceous material. No evidence for the previously suspected exchange between the outer- and inner solar system reservoirs was found.
Therefore, the Earth grew within a relatively static system, incorporating its smaller neighbouring planets as it grew. This also implies that most volatile elements, such as water, must have already been present in the inner Solar System.
Jupiter acts as a material barrier
But why are there two distinct material reservoirs in our Solar System? Researchers assume that our Solar System split into two reservoirs during its formation due to Jupiter’s rapid growth and size. The gravity of the gas giant tore a gap in the protoplanetary disc orbiting the young Sun. These discs are ring-shaped and consist of gas and dust; they are the birthplace of planets. Jupiter prevented material from the outer solar system from entering the inner region. However, the extent to which this barrier was permeable remained unclear until now.
In their new analysis, the two ETH researchers demonstrate that almost no material from beyond Jupiter flowed towards Earth. “Our calculations are very robust and rely solely on the data itself, not on physical assumptions, as these are not yet fully understood,” Bower emphasises. The analysis also shows that Earth's material composition is similar to that of Vesta and Mars.
The researchers also suspect that Venus and Mercury lie on the same line. “Based on our analysis, we can theoretically predict the composition of these two planets,” says Paolo Sossi. However, he cannot verify this analytically, as no rock samples from Mercury and Venus, which are the two innermost planets in the Solar System, are currently available to the researchers.
New light on the formation history
“Our results shed new light on the formation history of our Earth and the other rocky planets,” says Sossi.
Sossi and his team intend to follow up by investigating why there was sufficient water in the hot, inner Solar System to form the Earth’s oceans. Furthermore, they will examine whether these processes can be applied to exoplanetary systems.
“Until then, however, Dan and I will have to engage in many heated debates about the material composition of Earth and its neighbouring planets, because the scientific discourse over the building blocks of Earth is far from over, despite the new findings,” says Sossi.
