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......»»
HD 21997 is a high-frequency Delta Scuti pulsator, observations find
Using NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers have observed a young star designated HD 21997. Results of the new observations indicate that the studied object is a high-frequency Delta Scuti pulsator. The finding was describe.....»»
Gravitational waves reveal “mystery object” merging with a neutron star
The so-called "mass gap" might be less empty than physicists previously thought. Enlarge / Artistic rendition of a black hole merging with a neutron star. LIGO/VIRGO/KAGRA detected a merger involving a neutron star and what might.....»»
Teen’s vocal cords act like coin slot in worst-case ingestion accident
Luckily his symptoms were relatively mild, but doctors noted ulceration of his airway. Enlarge (credit: Getty | Archive Photos) Most of the time, when kids accidentally gulp down a non-edible object, it travels toward th.....»»
What"s the earliest the moon could have formed?
Astronomers are pretty sure they know where the moon came from. In the early solar system, a Mars-sized object dubbed Theia smashed into Earth. This cataclysmic collision knocked a huge mass of material into orbit, which coalesced and cooled into the.....»»
International Space Station Trash May Have Hit This Florida House
The object tore through the roof and both floors of a two-story home. NASA will investigate whether it’s space junk......»»
NASA collects "space debris" that crashed into Florida man"s home
NASA said Tuesday it was analyzing an object that crashed from the sky into a Florida man's home—which could well be a piece of debris jettisoned from the International Space Station......»»

Distant "space snowman" unlocks mystery of how some dormant deep space objects become "ice bombs"
A new study is shaking up what scientists thought they knew about distant objects in the far reaches of the solar system, starting with an object called the space snowman......»»
How Spanish conquistadors, and a tiny cactus-dwelling insect, gave the world the color red
When you think about a red object, you might picture a red carpet, or the massive ruby in the Queen's crown. Indeed, Western monarchies and marketing from brands such as Christian Louboutin have cemented our association of the color red with power an.....»»
Hubble sees new star proclaiming its presence with cosmic light show
FS Tau is a multi-star system made up of FS Tau A, the bright star-like object near the middle of the image, and FS Tau B (Haro 6-5B), the bright object to the far right that is partially obscured by a dark, vertical lane of dust. These young objects.....»»
Dogs’ brain activity shows they recognize the names of objects

Tropical birds could tolerate warming better than expected
Consider the globe, spinning silently in space. Its poles and its middle, the equator, remain relatively stable, thermally speaking, for the duration of Earth's annual circuit around the sun. The spaces between—Earth's temperate zones—experience.....»»
Study reveals ancient ice may still exist in distant space objects
A paper recently published in Icarus presents findings about the Kuiper Belt Object 486958 Arrokoth, shedding new light on the preservation of volatile substances like carbon monoxide (CO) in such distant celestial bodies......»»

Trapping and excitation of the simplest molecule: Precise measurement matches theoretical predictions
The simplest possible molecule H2+ was one of the very first molecules to form in the cosmos. This makes it significant for astrophysics, but also an important object of research for fundamental physics. However, it is difficult to study in experimen.....»»
Earth as a test object to evaluate the planned LIFE space mission
Physicists at ETH Zurich and the University of Zurich wanted to know whether the planned LIFE space mission could really detect traces of life on other planets. Yes, it can, say the researchers, with the help of observations of our own planet......»»
A mass of 17 billion suns: Growing black hole is the most luminous object ever observed by astronomers
A new study published in Nature Astronomy describes the most luminous object ever observed by astronomers. It is a black hole with a mass of 17 billion Suns, swallowing a greater amount of mass than the sun every single day......»»
Astronomers detect a new short-period brown dwarf
While analyzing the data from the Next Generation Transit Survey (NGTS), an international team of astronomers has discovered a new brown dwarf. The newfound object, designated NGTS-28Ab, orbits its host star in just about 30 hours. The finding was re.....»»
Nightmare black hole is the brightest object in the universe
