Strange signals detected beneath Antarctica

1 week ago | techexplorist.com | Amit Malewar

Neutrinos are ghostly particles—no charge, barely any mass, and yet they flood the cosmos. Born in places like the Sun, exploding stars, and even the Big Bang itself, they race through us by the trillions every second, silently. But here’s the twist: they’re almost impossible to catch. That’s why scientists build ultra-sensitive detectors, buried deep underground or beneath ice, in an attempt to hear just a faint “ping” from these elusive messengers.
Physicists recreated extreme quantum vacuum effects

A quantum vacuum is a state that is assumed to be empty. However, quantum physics predicts that it is full of virtual electron-positron pairs.
Mars Odyssey spots towering volcano above dawn clouds

3 weeks ago | techexplorist.com | Amit Malewar

NASA’s 2001 Mars Odyssey orbiter has delivered a breathtaking, first-of-its-kind panorama of Arsia Mons, one of Mars’ tallest volcanoes, which pierces through a layer of early morning clouds. This image offers a new perspective, showing the Martian horizon as astronauts see Earth from space. Arsia Mons, part of the Tharsis Montes volcanic chain, rises 12 miles (20 km) above the surface, twice the height of Mauna Loa, Earth’s largest volcano.
Webb confirms Pluto's atmosphere cools with haze

In the distant reaches of the Kuiper Belt, Pluto and its largest moon, Charon, boast strikingly diverse surfaces, yet their thermal and energetic mysteries remain unsolved. Scientists have struggled to accurately measure their temperatures because past observations blurred the two worlds together, making it hard to distinguish Pluto’s icy plains from Charon’s rugged terrain. But the intrigue doesn’t stop there.
Astatine-188: The heaviest proton emitter discovered

3 weeks ago | techexplorist.com | Amit Malewar

Proton emission is a rare form of radioactive decay in which the nucleus emits a proton, taking a step toward stability. The radioactive decay of atomic nuclei has been a cornerstone of nuclear physics since the inception of nuclear research. In a groundbreaking experiment, physicists at the University of Jyväskylä have detected the heaviest nucleus ever recorded to decay via proton emission—a rare phenomenon in nuclear physics.
Japan's ispace's RESILIENCE lunar lander crashed on the moon

3 weeks ago | techexplorist.com | Amit Malewar

In a daring attempt to expand commercial lunar exploration, Japan’s space agency aimed to make history with an ambitious lunar mission, Mission 2 SMBC x HAKUTO-R Venture Moon. However, the mission came to an abrupt end as Espace’s RESILIENCE lander likely crashed onto the lunar surface. Early on June 6, 2025, the lander executed its landing sequence, descending from an altitude of 100 km to 20 km and successfully firing its main engine for deceleration.
Supermassive black holes feasting on massive stars

3 weeks ago | techexplorist.com | Amit Malewar

Black holes are nature’s ultimate shadow dwellers—silent, invisible unless they interact with their surroundings. Some continuously devour gas and dust, glowing eerily as matter spirals inward. Others, however, lie in wait for years, lurking undetected until an unsuspecting star drifts too close. A new study utilizing NASA, ESA, and ground-based observatories has captured three extreme examples of supermassive black holes violently consuming massive stars.
The most precise measurement of the muon's magnetic anomaly

3 weeks ago | techexplorist.com | Amit Malewar

Imagine a tiny cosmic dancer—the muon—twirling through the quantum stage like its well-known sibling, the electron. But there’s a twist! This subatomic performer carries an invisible magnet, and the strength of its spin is measured by a special number called “g.” Ideally, g would be 2, but nature has a sneaky habit of bending the rules. Why? Because the muon doesn’t exist in isolation.
New 3D printing method for making intricate structures with less waste

3 weeks ago | techexplorist.com | Amit Malewar

Vat photopolymerization — a form of 3D printing is the process behind manufacturing hearing aids, mouth guards, dental implants, and other highly tailored structures. The process uses light patterns to shape and solidify a resin. Vat photopolymerization (VP) begins with a 3D computer model, such as interlocking gears. The model features support structures to maintain its position during printing. This model is sliced into digital layers, which are sent to the printer.
The longest and most complex simulation to date of a binary neutron star merger

3 weeks ago | techexplorist.com | Amit Malewar

In the grand theatre of the universe, few events rival the spectacle of two neutron stars colliding. These incredibly dense remnants of exploded stars spiral toward each other in a cosmic ballet, generating ripples in space-time, gravitational waves, and a shower of high-energy radiation across the cosmos.
