A neutron star is the remains of a once massive star that died in a supernova explosion. As a whole, neutron stars are considered some of the most extreme objects in the known universe – and this is especially true when these incredibly dense stellar remnants exist alongside companion stars (that are not yet “dead”)… Read More »
One day in the next few years, everyone in the world will lose a second of their time. Exactly when this will happen is influenced by people, according to a new study; because melting polar ice changes the rotation of the Earth and changes time. The hours and minutes that determine our days are determined… Read More »

Global warming has slowed the Earth’s rotation slightly, and this may affect how we measure time. A study published Wednesday found that melting polar ice — an accelerating trend driven primarily by human-caused climate change — is causing the Earth to spin less quickly than it normally does. The study’s author, Duncan Agnew, a geophysicist… Read More »
Andreas Mogensen He was impressed with how smooth the landing was. The first European Space Agency (ESA) astronaut (and the first non-American) to pilot a U.S. commercial crewed spacecraft, Mogensen and the SpaceX Crew-7 crew returned to Earth after a 197-day stay aboard the International Space Station. (ISS) on March 12. Speaking at his crew’s… Read More »
Many people assume that horses first came to America about 500 years ago when Spanish explorers brought them here. In fact, recent research has confirmed that horses associated with people in the American Southwest and the Great Plains are of European origin. But these were not the first horses in North America. The Equidae family,… Read More »
Considering that it was Navy ships that rescued the Apollo crew and spacecraft that crashed from the Moon, it’s fitting that the largest temporary exhibit ever hosted by the Intrepid, a converted aircraft carrier, is themed around the first Moon landing. The museum, which has been on Manhattan’s west side since 1982, has brought down… Read More »
NASA’s James Webb Space Telescope (JWST) is known for capturing our universe with unprecedented sensitivity and sensitivity. His images are not only scientifically useful but also beautiful. Of blue and gold Southern Ring Nebula pink, orange and purple Cassiopeia A.JWST images show the universe in bright colors. The images are so impressive that you may… Read More »

Now imagine something twice the size of a human. About 16 million years ago, a giant dolphin roamed the depths of the water space. But unlike most modern dolphins, its… Read More »
Humans are very good at spotting patterns, or recurring features that humans can recognize. Ancient Polynesians, for example, navigated the Pacific, recognizing patterns ranging from constellations of stars to more subtle ones such as the directions and sizes of ocean waves. Recently, mathematicians like me have begun to study large collections of objects that do… Read More »
