The solar storm in May did more than just produce exceptional auroras. An analysis of US Space Force data has found more than 5,000 satellites had to alter their position to avoid deorbiting or crashing into each other.​

The Olympic and Paralympic Games are approaching, but even elite sportspeople can find themselves unable to perform. Why do athletes "choke" under pressure, and how can they reduce the likelihood of it happening again?​

The world's largest iron ore deposits in the Pilbara reached mining-level quality up to 1.4 billion years ago, a new study suggests.​

Sparrows are often considered pests, but a new study suggests lead levels in the birds' blood could indicate if children in mining towns have been exposed to high levels of the poisonous chemical.​

Chandra launched in 1999 -- the same year Space.com started -- aboard Space Shuttle Columbia. From its egg-shaped orbit high above Earth's atmosphere that takes it over one-third of the way to the moon, the observatory has led to many discoveries by recording x-ray emissions beamed from long-dead stars, supermassive black holes and clusters of galaxies.

Scientists find 2 searched-for 'missing link' black holes
Scientists find 2 searched-for 'missing link' black holes
(Robert Lea)
For decades, astronomers have searched without much joy for signs of "missing link" black holes, aka black holes with masses between those of "stellar-mass black holes" and "supermassive black holes." The former have been seen scattered across the universe and the latter are cosmic titans that dominate the hearts of galaxies - but when it comes to intermediate-mass black holes, scientists have seen evidence of only about ten.

Satellites in SpaceX's Starlink megaconstellation made nearly 50,000 collision-avoidance maneuvers in the last six months, about double the number made in the previous half-year. Although experts praise Elon Musk's space compay for its commitment to transparency, they warn about the implications of the soaring orbital traffic.

SpaceX rocket failure shows need for multiple launch options
(SpaceX)
It's eerily quiet on the spaceflight front. In the past two weeks, there has been just a single orbital launch -- that of a Chinese Long March 4B rocket, which lofted the Gaofen-11 05 Earth-observation satellite on July 18. The lull stems chiefly from the temporary grounding of SpaceX's Falcon 9 rocket, which suffered an anomaly on July 11 that led to the loss of its payload, 20 of the company's Starlink broadband satellites.

The eyes, the old saying goes, are the window to the soul — but when it comes to deepfake images, they might be a window into unreality.That's according to new research conducted at the University of Hull in the U.K., which applied techniques typically used in observing distant galaxies to determine whether images of human faces were real or not.

The Perverse Legacy of Participation in Human Genomic Research


By Misha Angrist

The story of how one person became the majority source of DNA for the Human Genome Project encapsulates 20th-century researchers’ attitudes toward donor consent, says Duke University’s Misha Angrist. Even now, he argues, bioethicists consider hiding people’s own genetic information from them as the ethical thing to do — which is a shame. Read on »
