Within Months, 6 Quiet Galaxies Became Blazing Quasars And Scientists Don't Know How.Compared to our brief human lives, we tend to think of events on galactic scales as ones that happen extremely slowly. But that's not always the case.In a spectacular fashion, six galaxies have just undergone a huge transformation in a matter of mere months. They've gone from relatively peaceful galaxies to active quasars - the brightest of all galaxies, blasting vast amounts of radiation out into the Universe.This isn't just amazingly cool - these events could help to resolve a long-standing debate about what produces the light in a particular type of galaxy. In fact, they may indicate a previously unknown type of galactic nucleus activity.The six galaxies started out as low-ionisation nuclear emission-line region (LINER) galaxies; in terms of brightness, that's sort-of like being a galactic middle child.Making up a third of all known galaxies, they're brighter than ones with dormant supermassive black holes at the centre, but not as bright as active galaxies (known as Seyfert galaxies), whose supermassive black holes are chowing down on cosmic snacks.Now, quasar galaxies are the brightest of such active galaxies; in fact, they are among the brightest objects in the Universe. •••What do you think of this 🤔 💭?Tag someone to read this❤️😍•Discover the Cosmos with us 🔭 💫 & Follow us for more💖🙏 @intospace0• #quasar#galaxies#massive#supernova#stars#exploration#astronaut#spaceship#technology#constellations#universe#space#cosmos#spacetime#blackhole#planets#solarsystem#nebula#interstellar#milkywaychasers#outerspace#astronomy#astronomyphotography#nasa#hubbletelescope#science#scientist#astrophysics8h#toptorontotech CREDIT: @intospace0
This animation illustrates Jupiter's powerful magnetic field, based on data from the @NASAJuno probe. The gray lines (called field lines) show the field's direction in space, and the deepness of the color corresponds to the strength of the magnetic field. The Great Blue Spot, an-invisible-to-the-eye concentration of magnetic field near the equator, stands out as a particularly strong feature.
Information from Juno recently revealed that atmospheric winds deep inside Jupiter are likely responsible for variations in its magnetic field. The discovery will help scientists further understand the giant planet's interior structure — as well as changes in Earth's magnetic field.
Can you imagine what our skies used to look like before they were polluted with endless light? It must have been amazing. Taken outside of Hood River last month.

I am sharing this milky way image, not so much for the photo, but more for the story behind it. We went to a very small but interesting geological area in Nebraska. We finished shooting the foreground with our low level LED lights to illuminate the foreground, and began to shoot our sky images. I was shooting groups of 15 photos at different settings in order to stack the sky images for noise reduction. During one of the group shots, I noticed that the mountains were getting lighter and lighter in the distance. I blinked my eyes for a few seconds thinking I was having an eye problem, but the light just got brighter and brighter. All of a sudden the mountain range was completely lit up!!! It was then that I realized a UFO was about to land. I've seen "Close Encounters of the third kind" and i started to hear the familiar tones!!!! We looked all over the sky in front and behind us and saw nothing!! The mountains were just lit up as clear as day! Then, all of a sudden....we realized what had happened. There was a train coming down the railroad tracks about 2 miles away and its headlight was illuminating the mountains. We could not hear it until the whistle blew. Just as fast as the mountains lit up, they went back to being completely in the dark. Since I captured the "Daylight mountains' during my shoot, I decided to blend them into the image. I even got a bonus meteor on the right side of the sky!! The camera was never moved during the entire shoot. This is a 3 images exposure blend.
Nikon D850 with Nikkor 14-24mmF2.8 at 14mm. Sky Image, 15 images stacked using Starry Landscape stacker, ISO 10,000, F2.8, 10 sedconds.
I’ve always been in drawn to those flickering lights in the sky. Curiosity about their nature, awestruck by their grandeur, and sometimes, simply captivated by their mystery. It’s this sort of wonderment that keeps my mind young; it’s this sort of wonderment that will forever keep me looking up. Happy Friday friends ✌🏼

Never-before seen close up tour of our 4.5 billion year old moon.
This video was made thanks to data provided by NASA's Lunar Reconnaissance Orbiter (LRO) spacecraft. 🛰
To the center of our galaxy...💫 Who of you can find the pillars of creation in this shot? 😀

Right Chandra is studying a cluster of galaxies in Draco! Nearby in the sky is the Spindle Galaxy, NGC 5866. The outer halo of this galaxy is stippled with numerous globular clusters — gravitationally bound groups of containing nearly a million stars each!

“Neighbor Galaxy Andromeda” 🌌 First attempt on Andromeda
İlk defa fotoğraflamaya çalıştığım 2.5 milyon yılı uzaklıktaki komşu galaksimiz Andromeda (m31). İçinde bulundurduğu 1.2 trilyon yıldızla Samanyolu’nun iki katından da büyük bu galaksi saniyede yaklaşık 110km hızla bize yaklaştığı için 5 milyar yıl içinde çarpışmamız öngörülüyor. Bu fotoğraf herhangi bir teleskop kullanılmadan Dslr kamera 135mm lens ve bağlı oldukları bir kundakla 120saniyelik 25 karenin istiflenmesiyle elde edildi.
