Russia Is Leaving The International Space Station, in a Dramatic End of an Era
Moscow said Tuesday it was leaving the International Space Station "after 2024" amid tensions with the West, in a move analysts warned could lead to a halt of Russian-crewed flights.

Part of a Massive, Uncontrolled Rocket Will Crash to Earth This Sunday. Here's What We Know
This weekend, a massive, uncontrolled rocket booster is predicted to hurtle back to Earth, with a high chance that at least some of the debris will be large enough to survive the descent and smash into our planet.

Scientists have demonstrated a new system that can restore crucial molecular and cellular functions in pigs one hour after death. Experiments showed that some tissue damage from loss of oxygen can be reversed, which could widen the organ transplantation pool and may even lead to new treatments for heart attacks.

Deepwater Horizon Oil Spill Still Detectable 10 Years Later, Scientists Say
The Deepwater Horizon oil spill was not a short-lived catastrophe. Over 10 years after one of the largest environmental disasters in human history, a sticky oil residue still coats some marshland in the Gulf of Mexico, a new report reveals. Its i

What are the most depressing things about space exploration?

Kepler
This is Kepler-186f, the first planet with a radius similar to Earth to be discovered in the habitable zone of another star. However, Kepler-186f is more than 550 light-years away from Earth, while one light-year is around 5.9 trillion miles. In other words…

Gravity is often demonstrated in 2 dimensions like a heavy object on a bed sheet.
How does this actually translate into our 3 dimensional reality?
It actually contracts or squeezes the fabric of spacetime. But remember we live in a 4D world so you can imagine then why observers in a deep gravitational well observe time dilation.

This is an illustration of how much air and water there is on Earth. The water bubble contains all of the water on the planet, including the water locked in ice, floating in the atmosphere as water vapour, and hidden in aquifers underground. And the air bubble contains all air above the planet at one atmosphere pressure.
Most of that water is in the oceans.

Snakes have learned to "walk": blogger Allen Pan created an exoskeleton for crawling.
Snake can change directions with its head and tail.
During the first test snake behaved quite calmly and even seemed to be satisfied with this situation, not trying to escape.

The shell of Jupiter's famous ice moon may be formed, in part, by pure underwater snow that floats up instead of falling down.
A new study, published in the August issue of the journal Astrobiology, finds that Europa's icy crust might be built partially by "frazil ice," a fluffy accumulation of ice crystals that also builds up beneath ice sheets on Earth. This frazil ice holds a fraction of the salt found in ice that grows from the ice shelf itself, suggesting that Europa's ice sheets may be less salty than previously believed.

Following more than a decade of development, delays and testing, NASA's most powerful rocket ever now seems ready for liftoff. The Space Launch System and Orion spacecraft exited the vehicle assembly building yesterday, headed to the launchpad for a maiden journey around the Moon.
NASA laid out the potential launch windows for its uncrewed Artemis I demo last month, eyeing a series of dates on which the necessary elements would align for mission success. This involves timing the Moon's position in its lunar cycle for successful entry to orbit, mostly keeping the Orion spacecraft out of darkness and timing the capsule's return to Earth for a daytime splashdown.

Newly discovered crater suggests multiple asteroids killed dinosaurs
The Earth still bears the scar of the gigantic asteroid impact that wiped out the dinosaurs, along with three quarters of all life – but a new study suggests that killer rock wasn’t alone. Scientists have discovered a new crater in the seabed of the North Atlantic Ocean that seems to correspond to around the same time, suggesting the extinction event could have been triggered by multiple impacts.

Implantable "drug factory" beads destroy tumors in mice within days
Earlier this year, scientists at Rice University demonstrated a highly promising approach to tackling ovarian and colorectal cancer that centered on "drug factory" beads that could be implanted alongside tumors to destroy them in less than a week. By combining this technology with other immunotherapy drugs, the scientists have now explored the potential for this technique to tackle another form of cancer, and achieved very similar results.
The drug factory beads developed by the Rice University team are around the size of a pinhead and are loaded up with tens of thousands of cells genetically engineered to produce interleukin-2 (IL-2).
