Happy Easter to everyone who celebrates and those who don’t, have a great day :)
Light Years Across Golden Pillars Of Star Creation
This NASA Hubble Space Telescope image captures the chaotic activity atop a three-light-year-tall pillar of gas and dust that is being eaten away by the brilliant light from nearby bright stars. The pillar is also being assaulted from within, as infant stars buried inside it fire off jets of gas that can be seen streaming from towering peaks.
This turbulent cosmic pinnacle lies within a tempestuous stellar nursery called the Carina Nebula, located 7,500 light-years away in the southern constellation Carina. The image celebrates the 20th anniversary of Hubble’s launch and deployment into an orbit around Earth.
Scorching radiation and fast winds (streams of charged particles) from super-hot newborn stars in the nebula are shaping and compressing the pillar, causing new stars to form within it. Streamers of hot ionized gas can be seen flowing off the ridges of the structure, and wispy veils of gas and dust, illuminated by starlight, float around its towering peaks. The denser parts of the pillar are resisting being eroded by radiation much like a towering butte in Utah’s Monument Valley withstands erosion by water and wind.
Nestled inside this dense mountain are fledgling stars. Long streamers of gas can be seen shooting in opposite directions off the pedestal at the top of the image. Another pair of jets is visible at another peak near the center of the image. These jets (known as HH 901 and HH 902, respectively) are the signpost for new star birth. The jets are launched by swirling disks around the young stars, which allow material to slowly accrete onto the stars’ surfaces.
A CAT A FREAKING CAT GETS A STAR ON THE HOLLYWOOD WALK OF FAME AND I’M SITTING HERE WORKING MY BUTT OFF TRYING TO GET THROUGH COLLEGE AND MAKE A STANDARD LIVING AND THIS CAT MAKES A FROWNY FACE AT A CAMERA AND GETS A FRICKING HOLLYWOOD STAR NOPE NO I DID NOT SIGN UP FOR THAT
A dust cloud in NGC 281
Stars themselves can create huge and intricate dust sculptures from the dense and dark molecular clouds from which they are born. The tools the stars use to carve their detailed works are high energy light and fast stellar winds. The heat they generate evaporates the dark molecular dust as well as causing ambient hydrogen gas to disperse and glow red. Pictured above, a new open cluster of stars designated IC 1590 is nearing completion around the intricate interstellar mountain named NGC 281. The dust cloud NGC 281, dubbed the Pacman nebula because of its overall shape, is classified as a dense Bok Globule that lies about 10,000 light years distant.

The Lobster Nebula - NGC 6357
This image from ESO’s VISTA telescope captures a celestial landscape of vast, glowing clouds of gas and tendrils of dust surrounding hot young stars. This infrared view reveals the stellar nursery known as NGC 6357 in a new light. It was taken as part of the VISTA Variables in the Vía Láctea (VVV) survey, which is currently scanning the Milky Way in a bid to map our galaxy’s structure and explain how it formed.
