Stellar flybys can, in fact, reshape planetary systems – just look at this planet that was ejected from its orbit
Several million years ago, a binary star might have zipped past another pair of younger stars, thereby disrupting the orbit of a newly formed planet in the latter system. The researchers who made this astonishing discovery thought that this ancient stellar flyby might help explain the weirder parts in our solar system. Earlier efforts to […]

“Tree kill zone” in Yellowstone National Park hints at new magma activity below the surface
The massive amounts of magma slumbering beneath Yellowstone National Park stir anew. Researchers reported the appearance of a new thermal area in the park that killed off the plants in its vicinity. The area measured eight acres (3.2 hectares), enough to fit four soccer fields. It first appeared on infrared images taken by Landsat satellites […]

Scientists develop liquid that changes color with heat
Thermochromic materials are “smart” materials that change their color depending on the temperature of their surroundings. Recently, a Singaporean research team presented a liquid that grew much darker as it got hotter. Their invention might prove useful in smart windows and other applications that respond to temperature changes. Unlike earlier examples that relied on dyes […]

When galaxies collide, the resulting black hole is often kicked out of the galaxy
What happens when two galaxies that contain supermassive black holes come crashing together? Research indicates that the tremendous energies of the collision might shove the resulting celestial body away from the center of its newly merged home galaxy. The recently formed black hole might even end up cast out of the system. Black holes are […]

Foreign landscape: Scientists find vibrant “living rocks,” mirror pools on ocean floor
At the bottom of Mexico’s Gulf of California lies hydrothermal vents and cold seeps with hydrocarbon-rich fluids. A recent scientific expedition to this alien environment uncovered the existence of massive venting mineral towers that teemed with strange organisms. The towers reached heights of 23 m and widths of 10 m. Their volcanic flanges heated the […]

Why does coral have creatures that make chlorophyll but don’t photosynthesize?
What do you call a tiny critter that lives in most corals and creates chlorophyll but doesn’t bother using it to turn sunlight into energy? Dubbed corallicolid, this unusual creature is the first known organism that is capable of phototropic behavior yet doesn’t perform photosynthesis. Corallicolids belong to the phylum Apicomplexa. Its relatives include the […]

Bacteria may travel around the world using “air bridges,” explaining how superbugs share genes
Bacteria do not need animal or human carriers to spread. A Rutgers-led study suggests that microbes take advantage of natural air currents and use them as bridges to travel from one remote location to another. The genes that encode antibiotic resistance in bacteria appear in many seemingly unrelated bacterial species. Even microbes separated by thousands of miles rely […]

What are traveling-wave tubes and how important are they in space exploration?
Telecommunications and space exploration owes a lot to the traveling-wave tube. Invented in the 1950s, the simple and unassuming electron device has performed its job so well that modern-day space probes and satellites still use it for long-range communications. Abbreviated as TWT — and read as the rather rude “twit” – the traveling-wave tube is a vacuum tube […]

Researchers discover a planet orbiting a star rocked by “starquakes”
The first exoplanet found by NASA’s TESS space telescope dances around a similarly exciting star. The planet is a type of gas giant called a “hot Saturn” while the system primarily displays signs of “starquakes.” Experts say that stars sometimes experience seismic waves. The oscillations produced by these starquakes disrupt the brightness of their host. […]

Archaeologists uncover a dark chapter in Ancient Egyptian history: 60 Mummies found with evidence of GRUESOME deaths
Researchers finally dared to explore the grisly fates of the occupants of a tomb in Deir el Bahari, Egypt. They believed that the 60 mummies in the “Tomb of the Warriors” were soldiers who fell in battle during turbulent times in ancient Egypt. First discovered during the 1920s, the Tomb of the Warriors got sealed up in […]
