How to thermally cloak an object
Can you feel the heat? To a thermal camera, which measures infrared radiation, the heat that we can feel is visible, like the heat of a traveler in an airport with a fever or the cold of a leaky window or door in the winter......»»
Physicists have created “everlasting bubbles”
One gas bubble lasted for a whopping 465 days, a world record for this type of object. The shell of a water/glycerol gas marble (bubble) remains liquid and spherical even after 101 days, and it reacts as a liquid film when punctured. T.....»»

Astronomers find mysterious dusty object orbiting a star
The Transiting Exoplanet Survey Satellite, TESS, was launched in 2018 with the goal of discovering small planets around the sun's nearest neighbor stars. TESS has so far discovered 172 confirmed exoplanets and compiled a list of 4703 candidate exopla.....»»
The mystery of the small dimensionless number with a big effect
Non-dimensional numbers may sound like a scary, incomprehensible term reserved for scientists in a laboratory, but you have more experience with them than you know. The Mach number measures the speed of an object relative to the speed of sound, so wh.....»»
NASA probe becomes first in history to ‘touch’ the sun
A NASA probe has “touched” the sun, making it the first human-made object to do so in a feat described by the agency as “one giant leap for solar science.”.....»»
NASA"s "Eyes on Asteroids" tool reveals near-Earth object neighborhood
Through a new 3D real-time visualization tool, you can now explore the asteroids and comets that approach Earth's orbital neighborhood—and the spacecraft that visit these objects—with a click or a swipe. NASA's Eyes on Asteroids brings this data.....»»
Tesla"s autopilot feature is impressive, but it"s not perfect — Future Blink
This footage allows us to look through the “eyes” of Tesla’s autopilot tech. The self-driving feature is quite capable and offers some impressive object detection technology, but it’s still not completely problem-free......»»
Citizen scientists find young-Jupiter-like object missed by previous exoplanet searches
Citizen scientists have discovered a new object orbiting a Sun-like star that had been missed by previous searches. The object is very distant from its host star—more than 1,600 times farther than the Earth is from the Sun—and is thought to be a.....»»
Gemini South telescope catches a one-winged butterfly
This breathtaking visible-light image, taken with the Gemini South telescope, looks as though it is ready to flutter off the screen. This apparently wispy object is an outflow of gas known as the Chamaeleon Infrared Nebula—so named because it is br.....»»
