Sentinel-4 offers first glimpses of air pollutants

The new Copernicus Sentinel-4 mission has delivered its first images, highlighting concentrations of atmospheric nitrogen dioxide, sulfur dioxide and ozone. Despite being preliminary, these images mark a major milestone in Europe’s ability to monitor air quality all the way from geostationary orbit, 36,000 kilometers above Earth.

Magnetized plasmas offer a new handle on nanomaterial design

Imagine a cloud that shines like a neon sign, but instead of raindrops, it contains countless microscopic dust grains floating in midair. This is a dusty plasma, a bizarre state of matter found both in deep space and in the laboratory.

How a trick from radio astronomy could help astronomers find Earth-like planets

The wavelengths of radio light are so large that you can’t capture a high-resolution image with a single dish. To capture an image as sharp as, say, the Hubble telescope, you’d need a radio dish tens of kilometers across. So radio astronomers took a different approach. They used an array of dozens of antennas, each […]

Do These NASA Images Prove There Are ‘Alien’ Structures On The Moon’s Surface?

YouTube Video Here: https://www.youtube.com/embed/6Rj_wif2BD0?feature=oembed&enablejsapi=1

Whenever you put the words moon, alien, and base into one sentence you get the perfect recipe for a conspiracy theory.

The moon itself is a mysterious place, not only because we know very little about it, but because it has greatly influenced society throughout history.

In modern times, now […]

Hera and Europa Clipper will pass through 3I/ATLAS’ tail

All sorts of crazy things have been suggested regarding 3I/ATLAS, the third known interstellar object that we’ve discovered. Some are simply conspiracy theories about it being an alien spacecraft, while others have been well-thought-out suggestions, like using Martian-based probes to observe the comet as it streaked past the red planet. A new paper pre-published on […]

Nonlocality-enabled photonic analogies unlock wormholes and multiple realities in optical systems

Researchers have harnessed nonlocal artificial materials to create optical systems that emulate parallel spaces, wormholes, and multiple realities. A single material acts as two distinct optical media or devices simultaneously, allowing light to experience different properties based on entry boundaries. Demonstrations include invisible optical tunnels and coexisting optical devices, opening new avenues for compact, multifunctional […]

Exotic roto-crystals can break into individual fragments then reassemble themselves

It sounds bizarre, but they exist: crystals made of rotating objects. Physicists from Aachen, Düsseldorf, Mainz and Wayne State (Detroit, U.S.) have jointly studied these exotic objects and their properties. They easily break into individual fragments, have odd grain boundaries and evidence defects that can be controlled in a targeted fashion.
