Check _stardust90's Instagram @Regrann from @astrophysics.man -  Every star will pass through a phase of expansion in which the star may expand to become many times its original size. This phase, called the red giant phase, occurs as a star begins to run low on its hydrogen fuel. 
Since its formation, every star is powered by the fusion of hydrogen into helium in the core. This outward flow of energy is repelled by another force: gravity. Both gravity and the outward flow of energy from the star's core create an equilibrium, yet it will not last forever. Only a finite supply of hydrogen exists in the star's core, and thus one day it will run out. When this happens, the gravity of the star takes over and compresses the star. This compression causes the internal temperatures to increase, allowing the star to fuse helium in the core. The star may contract by about 98%. The zone of hydrogen fusion will migrate away from the core. The core of the star is now growing denser and hotter until eventually its energy causes the outer layers of the star to expand outwards. The star will begin to swell, becoming many times its original size. As it gets larger, the temperature of the outer layers cool and become red in colour. The result, a red giant star.

Most stars are so far away that even large telescopes see them only as points of light. Yet some stars are so large that careful observations from Earth can discern much detail. These are the red giants. Although red giant stars are large in size, their masses can be no different than the sun's. Yet these stars are so swollen that the Earth's orbit could fit inside of one. 
Due to their large size and normal mass, red giant stars have a hard time holding onto themselves. Over time, the outer layers of the star are blown off into space and form a planetary nebula around the dying star. For stars several times the mass of the sun, a planetary nebula will not form. Rather, the core collapses and the outer layers rebound and explode in a spectacular supernova explosion.

Deep within the Orion Molecular Cloud Complex lies the gorgeous nebula Messier 78. Located about 1,600 light years away in the constellation Orion, Messier 78 is a reflection nebula. This type of nebula is a nebula which reflects light from nearby stars, causing it shine brightly. M78 cannot be seen with the naked eye. However, a small telescope can. Through a telescope it appears as a small hazy patch. M78 has a radius of about 5 light years.

Hubble captured this amazing view of the Lagoon Nebula. The Lagoon Nebula is an emission nebula and an H ll region located in the constellation Sagittarius some 4-6 thousand light years away. The Lagoon Nebula is an H ll region, meaning that star formation is currently taking place or has recently taken place. The Lagoon Nebula is one of the closest active star forming regions visible to the naked eye, although when viewed through binoculars or a telescope it appears much more beautiful. The Lagoon Nebula contains Bok globules, which are dark collapsing clouds of protostar material. These regions will become the birth places of new stars and planets.

Check thebodyastrologer's Instagram Lemme explain my badass rhyme: crystals are the most dense form of earth (cold + dry). OK ONWARD. In my medical practice, I work with the elements. That’s how I see the world, the body and remedies. Let's get you prepped for my new project #MOONRX and have elemental game time. 🙌🏼
•
Below is a breakdown of today's astro by element and quality. In the comments, I want you guys to name as many remedies as you can to oppose the astro-weather in order to bring a body or psyche back into balance. It doesn't have to be at all medical, it can be ceremonial.
•
No, the astro-weather is not "bad". But too much of any quality beaming down through the heavens can cause a disruption in balance.
•
ASTRO-WEATHER REPORT:
.
-Sun in Aquarius // Air (typically HOT + MOIST, but Aquarius is the COLDEST sign in the zodiac. Just trust me on this one)
.
-Moon in Capricorn (at 2:43pm PST) // Earth: COLD + DRY
.
-Moon conjunct Saturn // COLD + DRY
.
-Waning Crescent Moon // Water: COLD + WET
.
-Mars in Pisces // Water: COLD + WET.

Image: Centaurus A
Active galaxies, like Centaurus A shown above, emit more energy in one second than our Sun will emit in 30,000 years. Surprisingly, however, all this energy comes from a region in the galaxy only a few light years across. However, within this relatively small region of space there exists a supermassive black hole. It's extreme gravitational pull can rip stars apart and "sucks" material inward. As the matter falls into the black hole it gives off a gigantic flood of radiation, making these galaxies the powerhouses of the universe. 
Active galaxies are the most powerful objects in the universe. They each emit huge amounts of radiation from their cores. Astronomers believe that each active galaxy is powered by the same process: a supermassive black hole. As huge amounts of matter falls into the black hole they create a disk like structure around the black hole. Friction is generated as the matter swirls inward. By the time the matter reaches the innermost edge of the disk, its temperature begins to increase. It increases so much in fact that it gives off a flood of X-rays, this is why active galaxies are so bright. Sometimes, as material falls into the black hole, huge jets of energy are emitted known as quasars.

Another type of galaxy which is not located on the Hubble sequence are ring galaxies. A ring galaxy has a central bulge and a ring-like structure located farther out. The ring contains young blue stars. The structure of the ring galaxy likely forms due to the collision of a smaller galaxy. A smaller galaxy which passes through the larger galaxy will distort its shape. As the smaller galaxy passes through the larger one, the gravitational interactions create the ring galaxy.

Image: Lenticular Galaxy, The Cartwheel Galaxy 
Lenticular galaxies are galaxies which are an intermediate between elliptical and spiral galaxies. Lenticular galaxies have a disk-like structure similar to spiral galaxies. Unlike spiral galaxies, however, lenticular galaxies have little to no interstellar matter, so star formation rarely takes place. So like elliptical galaxies, lenticular galaxies are composed almost entirely of older stars. 
There are two hypotheses that seek to explain the formation of lenticular galaxies. The faded spiral hypothesis proposes that lenticular galaxies were once spiral galaxies which have since used up all of its gas during star formation. After all the gas and dust within the galaxy is used up, star formation no longer takes place. Eventually, the galaxy may lose its spiral shape. It's also possible the the galaxy lost most of its gas and dust due to the gravitational interactions of other galaxies. 
The other hypothesis which tries to explain the formation of lenticular galaxies is the merging hypothesis. This idea states that lenticular galaxies are the result of other galaxies merging together. Evidence for this idea comes from the fact that lenticular galaxies have a much higher surface brightness than spirals, which can be explained if the galaxy formed from an earlier collisions. Also, globular clusters have also be known to be quite numerous within lenticular galaxies, which makes sense if the galaxy is the result of a collision.

Check astrophysicsman's Instagram The Hubble sequence is a classification for galaxies that Edwin Hubble invented in 1926. The sequence divides regular galaxies into three different types, elliptical, spiral, and lenticular galaxies. Today, the Hubble sequence is widely used by both professional and amateur astronomers to classify galaxies. 
To the left side of the diagram lie the elliptical galaxies. These galaxies are pretty much featureless. In fact, it's been said that if you've seen one elliptical galaxy then you've seen them all. This is because nearly every elliptical galaxy is very similar in structure and appearance. The largest galaxies in the universe, however, are elliptical galaxies and can contain more than 1 trillion stars. 
Moving to the right of the diagram, we see two parallel branches, both containing spiral galaxies. Unlike elliptical galaxies, spirals have amazing, stunning features. Spiral galaxies are basically flattened disks with huge spiral arms composed of stars, gas and dust. Spiral galaxies have a central region known as the bulge. For most spiral galaxies, a supermassive black hole exists in this region. The upper branch contains the regular spiral galaxies, which are denoted by the letter S. The lower branch contains the barred spiral galaxies, which are denoted by the letters SB. These galaxies can be further divided into other groups shown in the diagram.

Just before the diagram breaks off into the two branches which contain the spiral galaxies, we find the intermediate galaxies between elliptical and spiral galaxies, known as lenticular galaxies. Lenticular galaxies are given the symbol S0. Like spiral galaxies, lenticular galaxies have a disk like structure and a central bulge. Unlike spiral galaxies. the disks of lenticular galaxies have no visible spiral structure. Like elliptical galaxies, lenticular galaxies galaxies have very little star formation. Well, to know more follow me. 1434875340107237332_4008710248

Sometimes galaxies interact with each other and can even merge to form new galaxies. NGC 3169 and NGC 3166 are interacting galaxies located in the constellation Sextans about 70 million light years away. The distance between these galaxies is about 50,000 light years. Galaxies such as these are gravitationally interacting. Eventually, these two galaxies may collide to form an entirely new galaxy, most likely an elliptical galaxy. Sometimes the gravitational interactions between galaxies can cause hydrogen within both galaxies to collapse, triggering star formation. During a galactic collision, neither Galaxy has enough momentum to keep going, thus they fall into each other and merge. During a galactic collision, very rarely do stars actually collide with one another. The distances between the stars is so immense that the chances of stars actually colliding is astronomically low.

Check astrophysicsman's Instagram Above image: Galaxy NGC 4921
Location: Coma cluster in the constellation Coma Berenices. 
Distance: 320 million light years. 
Galaxy Type: Barred Spiral

This gorgeous galaxy, called NGC 4921, is a barred spiral galaxy. The nucleus of NGC 4921 is surrounded by a bar structure containing newly formed hot blue stars. NGC 4921 is located near the centre of the Coma cluster and is moving at a relatively high velocity compared to the cluster itself. While observing NGC 4921, astronomer discovered that the galaxy is actually running short on hydrogen. This may be due to interactions with the galactic medium, which is stripping NGC 4921 of its gas.

The Whirlpool Galaxy is a spiral galaxy located some 30 million light years away in the constellation Canis Venatici and is about 60 thousand light years across. This beautiful galaxy can be seen by amateur astronomers, either through a telescope or binoculars. It's quite amazing how you can view an entire galaxy 30 million light years away through a small telescope or binoculars. 
The Whirlpool Galaxy, or just simply M51a, is a popular target for many astronomers. M51a offers scientists new information on the spiral structure of galaxies and galaxy interactions, as well as star formation. Like most galaxies, a supermassive black hole exists at the galactic  centre of M51a. 
M51a is currently interacting with a much smaller galaxy, NGC 5195. This interaction is causing enhanced star formation near the core of M51a. The gravitational interactions are compressing hydrogen, triggering intense star formation. Astronomers estimate that this will likely continue for another 100 million years.
