Northrop Grumman said it will apply artificial intelligence to significantly accelerate spacecraft development. The company says that integrating AI into the engineering process will shorten design cycles from years to hours. This approach combines mission expertise with advanced AI technology to improve speed and accuracy. It is intended to enable more complex and mission-critical space … Read more

For the first time in history, scientists create particles from empty space

by
Brighter Side of News

The universe appears to be mostly empty space. Once you remove the stars, planets, dust, and gas, there is nothing left. Physics tells a strange story. A vacuum isn’t really empty. It is full of restless energy and momentary quantum fluctuations. These are short disturbances that can generate pairs of virtual particles before disappearing again. … Read more

The quantum arrow of time can be reversed, physicists show

by
Yahoo news home

The arrow of time moves forward. Eggs don’t break. Milk won’t spill. But now, new research has discovered a way to reverse this arrow in quantum systems, causing events to flip-flop as if time were flowing backwards. The finding is theoretical at this point, but could be tested experimentally, said Luis Pedro García-Pintos, a physicist … Read more

Purple-gold jumping spider (Irura bidenticulata)

If you were asked to imagine a spider, what would be the first thing you think of?For most people, that imagined creature would be beefy, black, hairy, with long legs and sharp fangs, and probably running around in the depths of a dark cave. I would like to suggest an alternative to the typical spider … Read more

Strong gravitational lenses captured by Euclid

science and exploration 2026/04/21 2706 view 34 like Simply put With the launch of Space Warps, a new citizen science project on the Zooniverse platform, you can now join the quest to find rare, elusive, and powerful gravitational lenses in never-before-seen images captured by the European Space Agency’s Euclid Space Telescope. The project aims to … Read more

Scientists observe particles emerging from empty space for the first time

by
earth snap

Researchers have detected pairs of particles emerging directly from vacuum during collisions of high-energy protons, providing the clearest evidence yet that mass can originate from empty space. This discovery reconfigures where much of the weight of ordinary matter comes from, pointing to space itself as an active source rather than a passive background. collision inside … Read more

Synthetic Universe allows us to ‘see and hear’ galaxies evolving from time immemorial (video)

by
Blue and purple web on background. The two insets show galaxies. The first image shows the spiral viewed from above, and the other shows the galaxy edge-on. The latter looks more like a line.

Have you ever dreamed of witnessing the birth of the first galaxies? Perhaps you could fast-forward through billions of years of the evolution of the universe and watch those galaxies grow and form the universe we know today? Of course, unfortunately that’s not possible. But thanks to an innovative new and unique audio-visual simulation of … Read more

Japanese private spacecraft to investigate two satellites that will disappear in 2027 for the first time

Private Japanese Spacecraft Set To Inspect Two Defunct Satellites In 2027 For The First Time

Astroscale Japan We aim to change the landscape of satellite services. The ISSA-J1 mission is the first of its kind to inspect multiple defunct satellites in different orbits, providing important insights into the status of the satellites that were previously unattainable. This bold move represents a major step forward in space sustainability and in-orbit servicing … Read more

Lost in the View: Artemis II astronaut details space time

Astronauts on NASA’s Artemis II mission said their experience in space was so overwhelming that they were temporarily removed from the mission, offering a glimpse into the mental strain of human spaceflight. At a post-flight press conference Thursday at Johnson Space Center in Houston, the four crew members spoke not just of moments of distraction, … Read more

Einstein’s relativity theories power everyday navigation . (AI-generated image: OpenAI)

Every time you drive and use Google Maps to make a right turn or use GPS to tell a friend where you are, Albert Einstein’s two laws of relativity are invoked. This is the reason. GPS (Global Positioning System) relies on satellites orbiting at high speeds approximately 20,000 kilometers above the Earth. Clocks on these … Read more
