Don’t be fooled! The cosmic swirl of stars in this Hubble Space Telescope (@NASAHubble) image may seem tranquil and unassuming, but this spiral galaxy actually displays some explosive tendencies.
In October of 2011, a cataclysmic burst of high-energy gamma-ray radiation — known as a gamma-ray burst — was detected coming from the region of sky containing this galaxy. Astronomers believe that the galaxy was the host of the burst, given that the chance of a coincidental alignment between the two is roughly 1 in 10 million. At a distance of around 185 million light-years from Earth, it was the second-closest gamma-ray burst ever detected.

TONIGHT! There’s an Iridium flare a little before 7pm that I will attempt to capture and post - check out heavens-above.com for a list of flares near you; and if you have any questions about observing them, hit me up!
ALSO!!! There should be a pretty spectacular meteor shower on Wednesday night, so let’s hope for clear skies! 😍🛰✨🚀🔭
El cielo se tiñe de rojo en el crepúsculo cuando el aire está sucio con partículas (de ceniza, polvo, etc) y filtra la luz solar. La porción de luz solar con menor longitud de onda (violeta, azul y verde) rebota contra esas partículas y se dispersa (se diluye!), mientras que la de mayor longitud de onda (amarillos, naranja, rojos) pasa casi “sin problemas”. En el crepúsculo, el sol bajo atraviesa más cantidad de atmósfera, y en consecuencia encontrará más partículas que hacen que sólo pase la luz con tonos rojizos (mayores longitudes de onda). #red#picoftheday#myhome#sky#science
⭐Hey Rockstars! Today we’re taking a trip to an island that the Rockstars crew personally visited back in 2016 – Granite Island! 💕 This small island is located just off the mainland of South Australia, Australia, and is known by the local Ramindjeri people as Nulcoowarra. It’s about 80km south of Adelaide next to the town of Victor Harbour, in Encounter Bay.
The island is accessible off a causeway that extends from the mainland, and is famous for its historic penguin 🐧 colonies which have now sadly declined to a critical point, prompting the closure of a penguin rescue center that had operated for over 16 years. Unfortunately, if you ever visit, there likely won’t be any penguins to see... ☹
Onto the geology of Granite Island, though. Unsurprisingly, Granite Island features a great deal of granite! 😃 These intrusions were emplaced during the Delamerian Orogen, which you may be familiar with from our explanation of the Flinders Ranges, during the Cambrian and Ordovician periods.
As you can see from our photos, the granite boulders nowadays have some curious weathering patterns. In several places, they seem almost like layers peeling off, like an onion or the skin of an orange. This is what’s known as EXFOLIATION weathering! 🤗 As granitic plutons are created and emplaced beneath the surface of the earth in the crust, they are created in high-pressure environments. As the rocks are uplifted to the surface, they are exposed to erosion and decompression, and they want to expand. If the granite does not contain significant jointing systems to accommodate movement and expansion, the outer parts may expand faster than those parts in the center, creating what’s known as an EXPANSION JOINT that looks like an outer shell! 😱
Eventually these layers break away in sheets, giving it the exfoliation term. This can lead to large exfoliation domes as well. Of course, the breaking off of sheets of rock increase that rock’s susceptibility to other weathering processes such as freeze-thaw and water pressure. Rock exfoliation - what a cool process! 😎
Gotta love this Jovian planet 🔴 #Repost @nasajuno (@get_repost)
The Great Red Spot Plunge. Take a simulated flight into, and then out of, Jupiter’s upper atmosphere at the location of the iconic storm in this animation.
Data indicate the Great Red Spot is almost one-and-a-half Earths wide, and has roots that penetrate about 200 miles into the atmosphere. Head to the link in our profile to learn more.
What if trees didn't let their dying leaves fall to the floor? What if they clung onto the parts of them that are dead, that no longer serve them purpose, merely for the fact they were once alive?
The trees let their leaves fall.
Why do the leaves fall but the branches that hold them remain intact to the tree?
The leaves are dead, but the branches are but frail.
Let go of that which no longer gives you life, and do not kill that which has yet to die, that which has the ability to grow.
You must not fear Fall, but you must not let everything fall. Let go that which no longer serves purpose to you, and bear patience towards that which has potential. 🥀
