2–8 July 2023: Betelgeuse is going to blow – and we'll likely see it in our lifetime 😱😱 Plus new signals seen in the human brain, quantum computing advance and the mystery of Antarctica's blood falls 💧🧠🖥️ Here's our wrap of this week in science! #TWIS Click on the link in our bio for more ➡️ @ScienceAlert

What a dazzling rainbow spider! 🌈🕷️ Perhaps the most colorful spider in the world, Chrysilla volupe is a rare species in the family of jumping spiders (Salticidae), which has over 6,000 different species. Like many spiders, jumping spiders have four sets of eyes! But their eyesight is sharper than most, enabling them to stalk and pounce on prey with precision. This striking guy looks big, but he's probably smaller than your fingernail, even the larger species of jumping spiders are usually less than 25 mm long. Creepy crawly colorful C. volupe are found in India, Sri Lanka, Nepal, and Bhutan. Ferdinand Karsch first described the species in 1879, but the female wasn't identified until 139 years later, in 2018!  📷 @pavan_tavrekere

An affectionate moment captured in history🥰💋 Alexander Graham Bell plants a kiss on his wife, Mabel Hubbard Gardiner Bell, while she stands gracefully in a tetrahedral kite. This adorable snapshot was taken on 16 October 1903 in Baddeck, Nova Scotia. Bell is credited with patenting the first practical telephone in 1876, although some controversy surrounds who first invented the telephone. Beyond his renown as an inventor and engineer, it's perhaps less well known that Bell's curiosity extended to the world of biological inheritance – the passing on of genetic traits from parents to offspring. 📷 Unknown/Library of Congress

The official, processed JWST images of Saturn are here and they're just so much prettier than we could have ever imagined 😍🪐✨ This means that @nasa JWST has now photographed all 4 of our Solar System's giant planets. Scroll across to see 1. Saturn, 2. Neptune, 3. Jupiter and 4. Uranus, all photographed in near-infrared. If you look closely, you can even see three of Saturn's moons, Dione, Enceladus, and Tethys, to the left of the planet. 🔭🌝 Read more at the link in bio ➡️ @sciencealert

How much of the Solar System did you think was habitable? 🤔 The green spheres represent the volume of each planet or moon with a potentially suitable physical environment for most terrestrial microorganisms.  Enceladus (the sixth-largest moon of Saturn) has the smallest volume but the highest habitat-planet size ratio followed by Europa (one of Jupiter's moons).  Just because these environments are potentially habitable, doesn't mean there is any life though 🚀 📷 @nasa/UPR Arecibo

25 June - 1 July 2023: Pulsar timing arrays and Milky Way neutrinos helped scientists to make two MAJOR discoveries about the Universe😲 Plus lots more, this week in science! 📡🧠🌌💭🌍🧑‍💻 #TWIS Click on the link in our bio for more ➡️ @ScienceAlert 📷 Slide 1: OzGrav/Swinburne/Carl Knox

Anemia is commonly found in mummified ancient Egyptian children. A condition where the body lacks enough healthy red blood cells to carry oxygen to the body's tissues, it's not clear if anemia was the cause of their deaths but it likely contributed. Malnutrition, parasitic infections, and genetic disorders, which still cause anemia today all probably contributed to its common occurrence in ancient Egypt.

✨BREAKING SCIENCE NEWS! ✨ Physicists have detected the background hum of the Universe 😲🎶😍🔊💫📡 It's official. There's something out there shaking the stars in a way that can no longer be ascribed to chance. Several teams around the world have independently found a signal in the timing of flashing stars called pulsars that points to giant, long-wavelength gravitational waves rolling through the galaxy. Swipe to see animations depicting flashing, rotating pulsars! Teams in Australia, the US, Europe, China, and India are releasing their results simultaneously in a slew of papers. Gravitational wave astronomy is a relatively new field, following the detection of space-time ripples caused by two colliding black holes in 2015.  Click on the link in our bio for more ➡️ @ScienceAlert 📷 N.

High-energy neutrinos from inside our own galaxy hint at the origin of cosmic rays 😮🌌 ⚡👻✨😱🔭  Somewhere out in the depths of the Milky Way galaxy, something stirs. Powerful forces whip charged particles into an energetic frenzy of cosmic rays, launching them at velocities that near the speed of light. We may finally be close to pinning down their origins. A reanalysis of 10 years of data collected by the IceCube Neutrino Observatory in Antarctica has returned the most solid evidence to date of neutrino emissions from the center of our galaxy that point to long-sought sources of cosmic rays.

Evolution keeps designing crab shapes and no one knows why! 😲🦀 'Crabbiness' has evolved independently at least five times in the past 250 million years, and has also been lost multiple times. This repeated evolution of a crab-like body plan even has its own fancy name: carcinization. Why evolution keeps playing this shell game remains a mystery, but it just keeps happening! There are thousands of crab species, and scientists think studying them could unlock the secrets to how evolution shapes creatures based on environmental factors and genetic cues.
