When a SpaceX rocket created a spectacular fireball over Europe, scientists rushed to their lasers.
When a SpaceX rocket created a spectacular fireball over Europe, scientists rushed to their lasers. What they found was a permanent, human-made chemical fingerprint high above Earth.
In the early hours of February 19, 2025, the upper stage of a Falcon 9 rocket tumbled back to Earth, exploding into a fireball that made headlines from the UK to Poland. While stargazers marveled at the light show, a team from the Leibniz Institute of Atmospheric Physics saw an unprecedented sci
How a rugged, affordable, open-source microscope is revealing the secret lives of cells during the chaotic freefall of the "Vomit Comet."

As space agencies gear up for long-duration missions to the Moon and Mars, understanding how the absence of gravity affects living cells is crucial. We know astronaut cellular signaling—like insulin processing—is altered in space, but watching it happen in real-time has been extraordinarily difficult and expensive.
Are galaxies held together by invisible Dark Matter, or is our understanding of gravity fundamentally flawed?
Are galaxies held together by invisible Dark Matter, or is our understanding of gravity fundamentally flawed? Wide binary stars are finally providing the answer.
In the outer edges of galaxies, stars orbit much faster than Newton's and Einstein's laws of gravity predict. To explain this "low-acceleration anomaly," scientists invented Dark Matter—a hypothetical, invisible halo providing extra gravitational pull.
