NASA's Voyager 1 is about to become humanity's first object to reach one light-day from Earth as it pushes ever deeper into interstellar space.
A cosmic magnifying glass could reveal the same supernova two more times in roughly 70 years
Thanks to the gravitational lensing caused by a massive galaxy cluster and high-resolution images from the James Webb Space Telescope (JWST), astronomers discovered an exploding star when the universe was 4.9 billion years old. The discovery paper, posted to the arXiv preprint
Some of the oldest rocks ever discovered shed light on Earth's early history
Earth is approximately 4.5 billion years old, according to estimates. However, rocks dating back to the planet's earliest days are extremely rare. Hence the excitement over the discovery in northern China of some of the oldest known rocks on Earth, dating back 3.95 billion

We beat screwworm once. Here’s how we’re trying to do it again
Screwworm, which can devastate livestock, was eliminated from the U.S. in 1966. Now they’re back and the same old technique won’t be enough to get rid of them
A giant icy world hiding beyond Pluto could be our sixth dwarf planet
Astronomers have uncovered a potentially enormous new dwarf planet beyond Pluto, hidden for years in one of the most crowded regions of the night sky. The discovery of 2026 ED138 could expand the solar system's official dwarf planet family and hints that more mysterious worlds
Scientists discover a surprisingly simple way to turn coffee waste into fuel
Scientists have developed an efficient method to transform used coffee grounds into a potential source of biodiesel while preserving the leftover material for other renewable fuels and valuable chemicals. The discovery could turn millions of tons of discarded coffee waste into
California steels for storms that could trigger massive waves, flooding
California was bracing Friday for a storm series packing heavy rain and surf that could once again flood coastal communities and potentially send monster waves pounding shores.
SpaceX's Starship set for return to Earth after booster catch aborted
SpaceX said its Starship spacecraft was "healthy" as it orbited the Earth and on track to return Saturday to its Texas launch site, where Elon Musk's company was planning to "catch" the vehicle for the first time.
Why the brain’s ability to picture images may influence decision making
Some people are excellent at visualizing scenes and images in their head, while others can’t do it at all
SpaceX's Starship soars into orbit after booster explosion prevents an unprecedented double catch
SpaceX's attempt to recover its entire Starship back at the launch pad was thwarted when the booster fell into the Gulf of Mexico and exploded Friday, but the spacecraft still soared into orbit in its boldest test yet.
Yale scientists reveal what really slows aging and what doesn't
Yale researchers have discovered that certain prescription drugs, healthy diets, and exercise can measurably slow biological aging, while popular anti-aging supplements appear largely ineffective. Their analysis of 51 studies could transform how scientists evaluate anti-aging
5,000-year-old skulls reveal a disturbing secret of ancient Egypt's first kings
A 5,000-year-old mystery surrounding the tombs of Egypt’s first kings has taken a disturbing turn. Scientists reexamining 46 ancient skulls discovered evidence of potentially fatal head injuries in 18, suggesting that at least 39% of those studied may have been deliberately
The role of social relationships in scaling agricultural innovations: A dimension that remains underreported in research
A study published in Frontiers in Sustainable Food Systems reveals that, although partnerships and institutional collaboration feature prominently in climate-oriented agricultural research, their relationship with the scaling of innovations is rarely explicitly documented. The
Forcing yourself to smile can actually make you miserable
Smiling may not always make you happier, and new research suggests that forcing yourself to smile repeatedly could actually make you feel worse. In a University of Florida study involving more than 1,100 participants, researchers discovered that while a single artificial smile
