What new exercise methods can be devised for astronauts in space under microgravity conditions? This is what a recent study conducted submitted to the 2025 Technology Collaboration Center’s (TCC) Wearables Workshop and University Challenge hopes to address as a team of Rice University engineering students developed a new type of space exercise harness that could make exercising under microgravity easier and more comfortable.

Stellar mass black holes are created by core-collapse supernovae. These occur when massive stars near the end of their lives collapse in on themselves and form a black hole. Supermassive black holes form through mergers with other massive black holes. But their could be a third kind, called direct-collapse black holes, and the JWST found evidence of one.

Lightning might not strike twice, but black holes apparently do. An international group of researchers led by Tel Aviv University astronomers observed a flare caused when a star falls onto a black hole and is destroyed.

We can understand how Earth formed by watching other planets form in distant solar systems. Powerful telescopes like the VLT are making that possible. New observations show a baby planet sculpting patterns in the gas and dust around its star.

It is true that crewed missions to the Moon are expensive, difficult, and dangerous.

Stars uncontaminated by heavier elements are thought to have formed very early in the universe, but a galaxy much later in cosmic history might let us see them for the first time

The spacecraft streaks through the darkness of space to reenter Earth's atmosphere.

It's no coincidence that a Klingon with a grudge follows the Enterprise's away mission to Kenfori.

NASA employees and allies protested sweeping science cuts they say are gutting the agency from within. As Congress pushes back on NASA leadership, workers warn the damage is already underway — and the future of U.S. space exploration is at risk.

Think: subzero temperatures, bone-rattling storms and mysteries about the future of our planet under the ice.

It's 1961, and four intrepid cosmic explorers journey to space under the leadership of Reed Richards, where they encounter cosmic rays that change them forever. But what are cosmic rays?

The newly waxing Moon passes Mars low in the west, then Spica and Antares while growing more robust. At dawn, Jupiter heads toward Venus.
