NASA’s Psyche captures images of Earth and moon

Headed for a metal-rich asteroid of the same name, the Psyche spacecraft successfully calibrated its cameras by looking homeward.

A decade of global water cycle monitoring: NASA soil moisture active passive mission

The NASA Soil Moisture Active Passive (SMAP) mission, launched in 2015, has over 10 years of global L-band radiometry observations. The low frequency [1.4 GHz frequency or 21 cm (8 in) wavelength] measurements provide information on the state of land surfaces in all weather conditions—regardless of solar illumination.

3D computational fluid dynamics illustrate badminton’s ‘spin serve’ phenomenon

One of the world’s most popular sports, badminton is played by around 220 million people across the globe. As with other racket sports, a well-executed serve can establish a consequential advantage at the start of a rally.

Physicists create stable, ‘breathing’ solitons in settings without energy conservation

Solitonic waves—waves that keep their shape and direction of motion for a long time—have intrigued physicists for almost two centuries. In real-world circumstances, these waves eventually die out due to energy loss. A team of UvA physicists have now discovered how a particular type of interaction can be used to create very stable solitons, even […]

LHCb collaboration observes ultra-rare baryon decay

Baryons, composite particles made up of three quarks bound together via the so-called strong force, make up the most visible matter and have thus been the focus of numerous physics studies. Studying the rare processes via which unstable baryons decay into other particles could potentially contribute to the discovery of new physics that is not […]

A 3D-printed aluminum mirror could enhance CubeSat observations

Compact, reflective, easy-to-manufacture mirrors are a critical component for advancing astronomical technology in space. Mirrors are a key component in most telescopes, though they are notoriously hard to manufacture with the necessary precision, especially at large scales. A new paper posted to the arXiv preprint server from researchers in the U.K. uses additive manufacturing to […]

Rare quadruple star system could unlock mystery of brown dwarfs

The exciting discovery of an extremely rare quadruple star system could significantly advance our understanding of brown dwarfs, astronomers say. These mysterious objects are too big to be considered a planet but also too small to be a star because they lack the mass to keep fusing atoms and blossom into fully-fledged suns.

Theoretical study reveals failure of key quark-gluon plasma probe in low-energy region

According to theoretical predictions, within a millionth of a second after the Big Bang, nucleons had not yet formed, and matter existed as a hot, dense “soup” composed of freely moving quarks and gluons. This state of matter is known as quark-gluon plasma (QGP). Finding definitive evidence for the existence of QGP is crucial for […]

Nikola Tesla’s lost papers—antigravity technology

As explained by Tesla himself, the Earth is “…like a charged metal ball moving through space”, which creates the enormous, rapidly varying electrostatic forces which diminish in intensity with the square of the distance from Earth, just like gravity. Since the direction of propagation radiates from the earth, the so-called force of gravity is […]

Astronomers discover dozens of new luminous quasars

Astronomers from Seoul National University, South Korea and elsewhere report the detection of 62 new luminous quasars as part of the All-sky BRIght, Complete Quasar Survey (AllBRICQS). The discovery was detailed in a research paper published August 8 on the arXiv preprint server.

Rapid-response protocol promises to reveal supernovae only hours after they explode

Supernovae appear to our eyes—and to astronomical instruments—as brilliant flashes that flare up in the sky without warning, in places where nothing was visible just moments before. The flash is caused by the colossal explosion of a star. Because supernovae are sudden and unpredictable, they have long been difficult to study, but today, thanks to […]

An asteroid wiped out a civilization like ours 13,000 years ago—and it could happen again in 2030

An extremely advanced ancient civilization—that flourished during the Ice Age—was wiped out from the surface of the planet some 13,000 years ago due to a massive comet strike, and the ancients left us a warning of future […]
