@PopCrave Hantaviruses are a group of viruses carried by rodents that can cause severe disease in humans. People usually get infected through contact with infected rodents or their urine, droppings or saliva. Infection with hantaviruses can cause a range of illnesses

A new study suggests a celestial shortcut to Mars by following the trajectory of asteroid 2001 CA21, potentially enabling a round trip in as few as 153 days. By using early orbital data from this asteroid, researchers found a path that slashes travel time compared to traditional methods

NASA's Parker Solar Probe, launched in 2018, is a historic mission designed to "touch the Sun" by orbiting through its outer atmosphere (corona). It is the fastest human-made object, reaching speeds over 430,000 mph, and uses a specialized heat shield to study solar wind and coronal heating at distances within 3.9 million miles of the surface

@michaelnicollsx @Starlink @SpaceX Starlink Group 10-38 was successfully launched on Friday, May 1, 2026, carrying 29 satellites into low-Earth orbit. A batch of 29 Starlink v2-mini satellites, which are part of SpaceX's second-generation constellation designed to provide high-speed, low-latency broadband internet
English
Stunning first-sat views from @Starlink launch G10-38 on May 1, deployed from @SpaceX's Falcon rocket. Watch as the Starlink sats cruise over an entire orbit, through sunrise and sunset, and slowly separate from each as they complete their post-launch deployment sequence before beginning orbit raise. The satellites are stacked like a deck of cards in the rocket, which slowly spins when dispensing to impart a small velocity difference, ensuring deconfliction. May the @Starlink be with you.

This is a Quetzalcoatlus, It lived approximately 68 to 66 million years ago. It is widely regarded as one of the largest flying animals to have ever existed on Earth
Its wingspan was about 10 to 11 meters (33 to 36 feet), which is roughly the size of a small private airplane or a standard city bus

Synaptogenesis is the biological process of creating new connections, or synapses, between nerve cells (neurons) in the brain. This process is essential for brain development, learning, memory, and neural plasticity, enabling the brain to form, refine, and reorganize its circuits throughout life
English
This is what a moment of learning looks like!
Process called synaptogenesis. This is the formation of new connections, known as synapses, between neurons in the brain.

If a helmet is completely rigid (hard to break), it transfers almost all the kinetic energy of an impact directly to the wearer's head and neck. This can lead to concussions, brain trauma, or skull fractures.
Mordern helmets are designed to crush or deform. By compressing during an impact, it slows down the head’s deceleration, absorbing the energy

Once food or liquid is swallowed, it enters the esophagus. The walls of the esophagus are lined with smooth muscles that engage in peristalsis.. a series of coordinated, wave-like involuntary muscle contractions.
These strong muscular contractions actively squeeze the food bolus downward, functioning independently of gravity. This is why humans can swallow effectively while lying down, or even upside down

The scale of this engineering is terrifying. 🤯
People don't realize this thing is alive.
It looks abandoned. It looks frozen. It looks forgotten.
It is none of those things.
The Kalyazin RT-64 is a 64-meter Soviet radio telescope, hidden in a Russian forest, still listening to deep space. To pulsars. To dying stars. To spacecraft drifting between planets.

@sciencegirl Cloud iridescence is an optical phenomenon where thin clouds, often near the sun, display pastel rainbow colors caused by the diffraction of light. It occurs when small, uniform water droplets or ice crystals in newly forming, thin clouds scatter light

The reactor uses High-Temperature Superconducting (HTS) magnets to create the massive magnetic fields needed for its compact design.
It also uses a unique "merging-compression" start-up to rapidly heat the plasma during initiation.

As your cells create energy and stay active, they emit microscopic, faint flashes of light.
It is about 1,000 to 1,000,000 times dimmer than what the human eye can see, which is why we cannot see it in the dark.
The glow is powered by your metabolism. The exact moment a body stops cellular activity, the chemical reactions stop, and the light goes out.

Scientists have discovered that living bodies emit an extremely faint form of visible light so subtle that it cannot be seen with the naked eye. Using highly sensitive imaging technology, researchers from the University of Calgary and Canada’s National Research Council were able to detect this phenomenon, known as ultraweak photon emission. To observe it, the team used advanced EMCCD cameras capable of capturing individual photons. They recorded light coming from living mice placed in complete darkness for about an hour. Afterward, they repeated the imaging once the mice had passed away while keeping their body temperature at 98.6°F (37°C). Maintaining the same temperature ensured that any changes in light emission were not related to heat. The results showed a clear difference. While alive, the mice released noticeably more visible photons from their skin. After death, the intensity of this light dropped dramatically, with only small amounts continuing to appear from internal organs such as the liver. Ultraweak photon emission occurs at extremely low levels roughly 10 to 1,000 photons per square centimeter per second. For context, even a very dim light bulb releases billions of photons in the same amount of time, which explains why this biological glow is invisible without specialized equipment. The light originates from normal cellular processes. As cells produce energy, they generate reactive oxygen species (ROS). When these molecules interact with lipids and proteins inside the body, they can create excited molecular states that release tiny flashes of visible light. Researchers also examined plants and noticed similar patterns. Leaves that were injured or chemically stressed produced stronger light signals, suggesting that the glow increases when organisms experience oxidative stress. Importantly, this phenomenon is different from body heat. Heat radiation from warm bodies mainly occurs in the infrared spectrum, whereas the photons detected in this study were in the visible range. Because this faint light is closely linked to metabolic activity and oxidative reactions inside cells, scientists believe it could eventually be used as a non-invasive way to monitor stress, disease, or the health of organs.

@astro_jaz Voyager 1 was launched by NASA in 1977, initially intended to study Jupiter and Saturn. After completing its planetary mission, it continued outward, eventually crossing the heliopause in 2012 to enter interstellar space

in case you wanted a perspective on the sheer size of the universe, the nearest star is proxima centauri, which is over 4 light-YEARS away.
the closest galaxy is 25,000 light-years away.
the observable universe is 93 BILLION light-years across.

in 6 months, voyager 1 will be one light DAY away from earth. any radio signals sent from earth will take 24 hours to reach the spacecraft.
