Curl up, read a new series of books, and be edified! Out now, Part 1, Vesha Celeste, and Part 2, Eliza Williams, have been paired together, and are available for those interested in the types and directions of science and the speculation that lead to well-being and quality of life. Please feel free to follow, message, share ideas, and be a part of a positive future where, if we choose, we can prepare properly to navigate the stars. This is just the beginning of this series and prequel, “Pathway to the Stars,” to an even more giant series, “Further than Before!” Please enjoy. https://www.amazon.com/author/matthewopdyke #sciencefiction #scifi #sciencefictionfantasy #scififantasy #politicalscifi #physiology #neurology #physics #Apolitical #strongfemalelead #biotechnology #neuroscience #theoreticalphysics #problemresolution #productivepursuits #spaceopera #cerebraldrama #sophisticateddialogue #solarsystem #spacemining #physiologicaloptimization, #neurologicaloptimization #transhumanism #universalethics #wellbeing #genetherapy #CRISPR #politicalsciencefiction #matthewopdyke https://www.instagram.com/p/BpUMW6ZgB1I/?utm_source=ig_tumblr_share&igshid=wy078mgrbgmm

The Universe's Brightest Lights Have Some Dark Origins

Did you know some of the brightest sources of light in the sky come from black holes in the centers of galaxies? It sounds a little contradictory, but it’s true! They may not look bright to our eyes, but satellites have spotted oodles of them across the universe. 

One of those satellites is our Fermi Gamma-ray Space Telescope. Fermi has found thousands of these kinds of galaxies in the 10 years it’s been operating, and there are many more out there!

Black holes are regions of space that have so much gravity that nothing - not light, not particles, nada - can escape. Most galaxies have supermassive black holes at their centers - these are black holes that are hundreds of thousands to billions of times the mass of our sun - but active galactic nuclei (also called “AGN” for short, or just “active galaxies”) are surrounded by gas and dust that’s constantly falling into the black hole. As the gas and dust fall, they start to spin and form a disk. Because of the friction and other forces at work, the spinning disk starts to heat up.

The disk’s heat gets emitted as light - but not just wavelengths of it that we can see with our eyes. We see light from AGN across the entire electromagnetic spectrum, from the more familiar radio and optical waves through to the more exotic X-rays and gamma rays, which we need special telescopes to spot.

About one in 10 AGN beam out jets of energetic particles, which are traveling almost as fast as light. Scientists are studying these jets to try to understand how black holes - which pull everything in with their huge amounts of gravity - somehow provide the energy needed to propel the particles in these jets.

Many of the ways we tell one type of AGN from another depend on how they’re oriented from our point of view. With radio galaxies, for example, we see the jets from the side as they’re beaming vast amounts of energy into space. Then there’s blazars, which are a type of AGN that have a jet that is pointed almost directly at Earth, which makes the AGN particularly bright.  

Our Fermi Gamma-ray Space Telescope has been searching the sky for gamma ray sources for 10 years. More than half (57%) of the sources it has found have been blazars. Gamma rays are useful because they can tell us a lot about how particles accelerate and how they interact with their environment.

So why do we care about AGN? We know that some AGN formed early in the history of the universe. With their enormous power, they almost certainly affected how the universe changed over time. By discovering how AGN work, we can understand better how the universe came to be the way it is now.

Fermi’s helped us learn a lot about the gamma-ray universe over the last 10 years. Learn more about Fermi and how we’re celebrating its accomplishments all year.

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.

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. 

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

(NASA)  Unexpected X-Rays from Perseus Galaxy Cluster

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.
