    Spaceships could use blinking dead stars to chart their way

    OXON HILL, Md. — Future spacecraft could navigate by the light of dead stars.

    Using only the timing of radiation bursts from pulsating stellar corpses, an experiment on the International Space Station was able to pinpoint its location in space in a first-ever demonstration. The technique operates like a stellar version of GPS, researchers with the Station Explorer for X-ray Timing and...

    Trio of dead stars upholds a key part of Einstein’s theory of gravity

    OXON HILL, Md. — Observations of a trio of dead stars have confirmed that a foundation of Einstein’s gravitational theory holds even for ultradense objects with strong gravitational fields.

    The complex orbital dance of the three former stars conforms to a rule known as the strong equivalence principle, researchers reported January 10 at a meeting of the American Astronomical Society....

    Pollution is endangering the future of astronomy

    OXON HILL, Md. — Even as technological advances allow astronomers to peer more deeply into the cosmos than ever before, new technologies also have the potential to create blinding pollution.

    Three sources of pollution — space debris, radio interference and light pollution — already are particularly worrisome. And the situation is getting worse. In the next two decades, as many as 20,000...

    View the video

    OXON HILL, Md. — Ever wonder what it would be like to sit at the center of the Milky Way and watch the galaxy swirl by? A video debuted in a January 10 news conference at the American Astronomical Society Meeting provides a glimpse.

    The 360-degree-simulation, made with data from several telescopes, including NASA's Chandra X-ray Observatory and the European Southern...

    18 new species of pelican spiders discovered

    Despite their name, pelican spiders aren’t massive, fish-eating monstrosities. In fact, the shy spiders in the family Archaeidae are as long as a grain of rice and are a threat only to other spiders.

    Discovering a new species of these tiny Madagascar spiders is tough, but Hannah Wood has done just that — 18 times over.

    Wood, an arachnologist at the Smithsonian National Museum of...

    Rising CO2 in lakes could keep water fleas from raising their spiky defenses

    Rising carbon dioxide levels could leave some tiny lake dwellers defenseless. Like the oceans, some lakes are experiencing increasing levels of the greenhouse gas, a new study shows. And too much CO2 in the water may leave water fleas, an important part of many lake food webs, too sleepy to fend off predators.

    Detailed observations of lake chemistry over long periods of time are rare....

    Hormone replacement makes sense for some menopausal women

    Internist Gail Povar has many female patients making their way through menopause, some having a tougher time than others. Several women with similar stories stand out in her mind. Each came to Povar’s Silver Spring, Md., office within a year or two of stopping her period, complaining of frequent hot flashes and poor sleep at night. “They just felt exhausted all the time,” Povar says. “The joy...

    Website invites you to probe a 3-D human brain

    In movies, exploring the body up close often involves shrinking to microscopic sizes and taking harrowing rides through the blood. Thanks to a new virtual model, you can journey through a three-dimensional brain. No shrink ray required.

    The Society for Neuroscience and other organizations have long sponsored the website BrainFacts.org, which has basic information about how the human...

    NASA is headed to Earth’s outermost edge

    NASA is going for the gold. Its GOLD mission — short for Global-scale Observations of the Limb and Disk mission — is slated for launch January 25, the agency announced January 4. GOLD will study the zone where Earth’s atmosphere meets outer space. Its goal is to better understand how both solar and terrestrial storms affect the ionosphere, an upper atmosphere region crucial for radio...
