Why does the Perseus galaxy cluster shine so strangely in one specific color of X-rays? No one is sure, but a much-debated hypothesis holds that these X-rays are a clue to the long-sought identity of dark matter. At the center of this mystery is a 3.5 Kilo-electronvolt (KeV) X-ray color that appears to glow excessively only when regions well outside the cluster center are observed, whereas the area directly surrounding a likely central supermassive black hole is actually deficient in 3.5 KeV X-rays. One proposed resolution – quite controversial – is that something never seen before might be present: florescent dark matter (FDM). This form of particle dark matter might be able to absorb 3.5 KeV X-radiation. If operating, FDM, after absorption, might later emit these X-rays from all over the cluster, creating an emission line. However, when seen superposed in front of the central region surrounding the black hole, FDM’s absorption would be more prominent, creating an absorption line. Pictured, a composite image of the Perseus galaxy cluster shows visible and radio light in red, and X-ray light from the Earth-orbiting Chandra Observatory in blue.

All Three Versions (chill, Rock, Orchestra) Further Than Before: Pathway To The Stars, Part 1 -- Audible

All three versions (chill, rock, orchestra) Further than Before: Pathway to the Stars, Part 1 -- Audible “Nature and humanity can be amazing, but likewise, it can be brutal. Brutality, as far too many know it, is unnecessary if we consider and implement one thing, innovation with purpose—a good purpose is brutality’s ideal replacement, and it comes minus unnecessary misery. It’s starting to become clear to me now what it is that we can do and how we can do it.” - Eliza Williams to Yesha Alevtina (Further than Before: Pathway to the Stars, Part 1) #books #sciencefictionbooks #SpaceOpera #scifi #ftbpathwaypublications #grahambessellieu #matthewjopdyke #politicalsciencefiction https://www.instagram.com/p/BxGfu74g5Vb/?igshid=16f1jd0ctbwq

How To Prove Einstein’s Relativity For Less Than $100

“But the fact that you can see cosmic ray muons at all is enough to prove that relativity is real. Think about where these muons are created: high in the upper atmosphere, about 30-to-100 kilometers above Earth’s surface. Think about how long a muon lives: about 2.2 microseconds on average. And think about the speed limit of the Universe: the speed of light, or about 300,000 kilometers per second. If you have something moving at the speed of light that only lives 2.2 microseconds, it should make it only 0.66 kilometers before decaying away. With that mean lifetime, less than 1-in-10^50 muons should reach the surface. But in reality, almost all of them make it down.”

Relativity, or the idea that space and time are not absolute, was one of the most revolutionary and counterintuitive scientific theories to come out of the 20th century. It was also one of the most disputed, with hundreds of scientists refusing to accept it. Yet with less than $100 and a single day’s worth of labor, there’s a way you can prove it to yourself: by building a cloud chamber. An old fishtank, some 100% ethyl or isopropyl alcohol, a metal base with dry ice beneath it and only a few other steps (see the full article for instructions) will allow you to construct a detector capable of seeing unstable cosmic particles. Yet these particles – and you’ll see about 1-per-second – would never reach Earth’s surface if it weren’t for relativity!

Come learn how you can validate Einstein’s first great revolution all for yourself, and silence the doubts in your mind. Nature really is this weird!

Constellations: Andromeda

Constellations: Andromeda

Andromeda is most prominent during autumn evenings in the Northern Hemisphere, along with several other constellations named for characters in the Perseus myth.

Its brightest star, Alpha Andromedae, is a binary star that has also been counted as a part of Pegasus, while Gamma Andromedae is a colorful binary and a popular target for amateur astronomers. Only marginally dimmer than Alpha, Beta Andromedae is a red giant, its color visible to the naked eye. The constellation’s most obvious deep-sky object is the naked-eye Andromeda Galaxy (M31, also called the Great Galaxy of Andromeda), the closest spiral galaxy to the Milky Way and one of the brightest Messier objects.

In this image of the Andromeda Galaxy, Messier 32 is to the left of the center.

Several fainter galaxies, including M31’s companions M110 and M32, as well as the more distant NGC 891, lie within Andromeda. The Blue Snowball Nebula, a planetary nebula, is visible in a telescope as a blue circular object.

NGC 891, as taken with amateur equipment

Along with the Andromeda Galaxy and its companions, the constellation also features NGC 891 (Caldwell 23), a smaller galaxy just east of Almach. It is a barred spiral galaxy seen edge-on, with a dark dust lane visible down the middle. 

Constellations: Andromeda

In addition to the star clusters NGC 752 and NGC 7686, there is also the planetary nebula NGC 7662.

Each November, the Andromedids meteor shower appears to radiate from Andromeda. The shower peaks in mid-to-late November every year, but has a low peak rate of fewer than two meteors per hour. Astronomers have often associated the Andromedids with Biela’s Comet, which was destroyed in the 19th century, but that connection is disputed. source

The spacecraft completely changed our view of Saturn and her moons

One of NASA’s greatest spacecraft will call it quits on September 15, 2017. The Cassini spacecraft has made countless discoveries during its sojourn to Saturn and its surrounding moons. It has also sent back nearly 400,000 images, many of which are purely spectacular, with surely more to come during the final months of the mission as Cassini explores new territory between Saturn and its rings.

In honor of the brave spacecraft, we spent hours sifting through the deluge of images to highlight some of Cassini’s best views from Saturn.

Pathway to the Stars: Part 2, Eliza Williams Audiobook Released!

Narrator Allison Taylor (Instagram: @alliptaylor) and Author Matthew J Opdyke have collaborated again following their previous release of the contemporary science fiction audiobook, Pathway to the Stars: Part 1, Vesha Celeste, and it is now available on Audible, Amazon, and iTunes.

In Pathway to the Stars: Part 2, Eliza Williams, Eliza and Yesha journey through their young lives together, sharing great ideas. “If we want to traverse the cosmos, we will need to be bringers of life, beauty inside and out, abundance, and have the ability to bridge understanding between multiple civilizations, so we can tackle even greater issues together.

"We need to understand how dark energy and dark matter work, find ways to slow down the expansion, or cause the Universe to breathe just enough to protect itself and all of life along with it. We need everyone willing."

Experience the early life of the scientific hero, Eliza Williams, and through her the beginning of a new era. Vesha Celeste continues her Virtual Universe training witnessing Eliza's life with experiential immersion, the added advantages of time-dilation, neural linking, tactile-reference, and more.

Engage yourself in the critical details, ups, and downs, leading to Eliza's transformation and the formation of her new organization. Eliza's first biopods for physiological and neurological optimizations will be among her primary vehicles driving advances and designs positively affecting human progress solar-system-wide. There is a lot for Vesha to learn, and through this, she will become phenomenal in intellect and abilities. Will Eliza be able to release everything right away? What measures will she take to protect humanity from her powerful tools if they were to get into the wrong hands?
