The history of life on Earth does not begin with the Cambrian Explosion. However, this was the time when almost all major animal groups appeared, proliferated and diversified. For centuries, scientists have debated what caused this sudden boom in diversity, without reaching clear conclusions. Now a team of scientists from Australia and Germany have proposed … Read more
A Japanese mission to bring samples from a Martian moon to Earth will launch into space from the southwestern prefecture of Kagoshima. The Martian Moons eXploration mission, or MMX, will lift off on an H3 rocket from Tanegashima Space Center around 4:41 a.m. Tuesday Japan time, which is 7:41 p.m. Monday UTC. The mission is … Read more
NASA’s Nancy Grace Roman Space Telescope is performing even better than scientists anticipated after engineers completed an extensive series of tests and fine-tuning. The work has brought the observatory’s powerful instruments into exceptionally sharp focus, and its main camera system now delivers almost 30% better image quality than anticipated. The achievement marks an important step … Read more
Do you want to educate young children about the wonders of the cosmos? Depending on the time of year, your location, and the weather, your hopes of seeing the night sky in real life may not be as easy as going to your backyard and looking up. That’s why one of the best star projectors … Read more

Through recent observations, astronomers have discovered that an exoplanet (technically a brown dwarf) that we have known about for years looks much more like our planet Earth than previously believed. The world, designated WISE 0855, has water clouds that are changing in thickness, indicating that it also has a progressive climate. WISE 0855 is a … Read more
Like the surface of an ocean, the fabric of the Universe constantly ripples with an infinite number of gravitational waves, which propagate outward through the cosmos. We can count, in three digits, the number of these waves we have detected to date, and most of them have been related to collisions between black holes, the … Read more
The world’s largest glacier is melting much faster and could raise global sea levels twice as much as expected over the next century. New research published this week by a team of glaciologists has found that the Thwaites Glacier in West Antarctica is rapidly losing mass as warm seawater pushes under it and melts its … Read more
“Necklaces” of ultracold atoms have provided new evidence supporting a nearly 100-year-old quantum theory. In 1931, physicists were trying to use quantum mechanics to explain why some materials are magnetic. Then, a young physicist named Hans Bethe observed a single row of electrons. The spin of each electron can point up or down. Bethe calculated … Read more
