Credit: Gerd Altman from Pixabay When atoms interact with each other, they act as a whole and not as individual entities. This can lead to simultaneous responses to inputs, a phenomenon that, if properly understood and controlled, could be useful for developing light sources, building sensors that can take ultra-precise measurements, and understanding dissipation in … Read more
Inside NASA’s Cold Atom Laboratory, scientists form bubbles of extremely cold gas, shown in pink in this illustration. The laser, also pictured, is used to cool the atoms, while the atom chip, shown in grey, generates magnetic fields to control its shape, in combination with radio waves.

PKS 0405-385: epoch folded pulse shape from 1022-day period negligible probability analysis of flux density. The purple dashed line represents the mean flux in the gamma-ray light curve. Credit: Gong et al. , 2022. By analyzing the historical light curve of Blazar PKS 0405-385 from NASA’s Fermi spacecraft, Chinese astronomers have detected a quasi-periodic oscillation … Read more
Side view of crater Moltke taken from Apollo 10. Credit: Public Domain Billions of years ago, a series of volcanic eruptions erupted on the moon’s surface, covering hundreds of thousands of square miles of the orb’s surface in hot lava. Over the ages, that lava created the dark spots, or maria, that give the moon’s … Read more
The charm (c) quark in the parton shower loses energy by emitting radiation in the form of gluons (g). The shower shows a dead cone of suppressed radiation around the quark for angles smaller than the quark’s mass (m) and energy (E) ratio. The energy decreases at each stage of the shower. credit: CERN ALICE’s … Read more
An illustration of a conventional modern nova shows a bright white dwarf star near the center accumulating fuel in an orange disk of its neighboring main-sequence star (highlighted in bright orange). Credit: NASA/JPL-Caltech Michigan State researchers helped peer inside a new supernova – a type of astrophysical nuclear explosion – without leaving Earth. These stellar … Read more
Astronomers have used a potentially unlikely tool to understand what they saw in their first historic image of the Milky Way’s supermassive black hole: a library of computer simulations that simulate a black hole with millions of variations. photo shoot Black holeLike Sagittarius A* In the center of our galaxy, with event horizon telescope (EHT) … Read more
An artist’s rendering shows how a group of galaxies (a lens cluster) acts as a gravitational lens that magnifies and expands light from a background galaxy. This results in a projected image (highlighted in the rectangular panel) that is brighter and easier to detect with a telescope. This allowed astronomers to use the Keck Observatory’s … Read more
Missile exhaust plume 30 km away as obtained by high-resolution computational fluid dynamics simulation. The temperature range is from 680 K (dark yellow) to 2400 K (bright yellow). Credit: Ioannis Kokinankis, Dimitris Drikakis, University of Nicosia, Cyprus Reusable space technology has led to an increase in less costly space transportation, as has been popularized by … Read more
