Continuing our look at Dyson Spheres we examine the concept of the Nicoll-Dyson Beam, a type of advanced weapon that uses the output of an entire sun to create a laser that can strike target across the galaxy.

A team of astronomers and citizen scientists has discovered a planet in the habitable zone of an unusual star system, including two stars and potentially another exoplanet.

The planet hunters spotted the Neptune-like planet as it crossed in front of its host star, temporarily dimming the star’s light in a way akin to a solar eclipse on Earth. This “transit method” usually identifies planets with tight orbits, as they are more likely to follow paths that put them between Earth and their host star and, when following such paths, move into light-blocking positions more frequently. That’s why this newly discovered planet is considered unusually far out, with the planet taking 272 days to lap its star.

Furthermore, the star is now by far the brightest one known to host a transiting planet in the habitable zone where liquid water can exist.

A Dyson sphere is a hypothetical giant structure that surrounds a star and can capture its solar output. Two separate groups of astronomers have claimed that they have detected dozens of possible Dyson spheres within the Milky Way galaxy. NBC’s Gadi Schwartz speaks with Dr. Michio Kaku about what it would take to create a Dyson sphere and how advanced a civilization would need to be to make it happen.

“The planet has a hot core, and that heat source is changing the chemistry of the gases deeper down, but it’s also driving this strong, convective mixing bubbling up from the interior,” said Zafar Rustamkulov.

Gas giant planets within our solar system and exoplanets outside our solar system are known to possess large amounts of gas and small cores, but what if an exoplanet was found to exhibit opposite characteristics? This is what a study published today in Nature hopes to address as a team of international researchers investigated the physical and atmospheric characteristics of WASP-107 b, which is located just over 200 light-years from Earth and has been found to have unique interior characteristics compared to previously discovered exoplanets. These unique findings hold the potential to challenge our understanding of the formation and evolution of gas giant exoplanets, which continue to demonstrate stark contrasts to planets within our solar system.

For the study, the researchers used NASA’s powerful James Webb Space Telescope (JWST) to observe WASP-107 b, discovering that while its radius is slightly less than Jupiter, its mass is only 10 percent of the largest planet in our solar system. Additionally, WASP-107 b possesses methane levels that are one thousand times less than what astronomers anticipated finding, along with having a core whose mass is 12 times larger than the Earth.

I don’t subscribe but if you do, you’ll get more but the short summary kinda gives a general idea. Astronomers spotted 60 stars with potential Dyson sphered around them but it isn’t 100% verifiable. It could be a simpler explanation they say.

Sufficiently advanced aliens would be able to capture vast quantities of energy from their star using a massive structure called a Dyson sphere. Such a device would give off an infrared heat signature — and astronomers have just spotted 60 stars that seem to match.

We are all very familiar with the concept of the Earth’s magnetic field. It turns out that most objects in space have magnetic fields but it’s quite tricky to measure them. Astronomers have developed an ingenious way to measure the magnetic field of the Milky Way using polarized light from interstellar dust grains that align themselves to the magnetic field lines. A new survey has begun this mapping process and has mapped an area that covers the equivalent of 15 times the full moon.

Many people will remember experiments in school with iron filings and bar magnets to unveil their magnetic field. It’s not quite so easy to capture the magnetic field of the Milky Way though. The new method to measure the field relies upon the small dust grains which permeate space between the stars.

The grains of dust are similar in size to smoke particles but they are not spherical. Just like a boat turning itself into the current, the dust particles’ long axis tends to align with the local magnetic field. As they do, they emit a glow in the same frequency as the cosmic background radiation and it is this that astronomers have been tuning in to.
