A tiny portion of the Rosette Nebula. Very dark gray material shaped like a shark’s fin extends from just below top left all the way down to the lower right corner and back up toward the top right. It looks like thick smoke that has billowed out irregularly, thicker along the line from top left to bottom right. Behind the dark gray on the left side, from the bottom left to top center, there are streaks that appear light orange and yellow. The background at top left is hazier and some blues are covered in semi-transparent orange wisps, which makes sections take on green hues. In the bottom right, the background is bluer. There are a few bright red and purple stars scattered along the right half, mostly toward the bottom. The largest star is at right-center, just at the edge. It is red and has four diffraction spikes.

In 2024, #Hubble observed a portion of the Rosette Nebula—a vast star-forming region located 5,200 light-years away. Hydrogen, oxygen, nitrogen, and dark clouds of dust contribute to this mesmerizing scene, which is four light-years long: https://bit.ly/4rndjuB

Pika what? Awesome. 😄

A white, glowing egg-shaped object lies in the centre of the black-and-white image, on a dark, starry background. Glowing streaks spread upwards from the object. In the top left, a yellow arrow marked ‘Sun’ points straight down, and a blue arrow marked ‘Velocity’ points towards the 7 o’clock direction. In the bottom left, an inset shows the same object on a lighter grey starry background, filled with ragged-edged, concentric egg shapes gradiented black-to-white.

Streaming is great until your favorites get nuked overnight. I’ve avoided that for decades: buy physical media, rip a 1:1 copy, and toss it on a personal server. Gives you that Netflix feel with absolute ownership. It is the best way to own what you love while keeping the ease of an app.

There is a paradox at the heart of Solar Orbiter.

On one hand, we wanted to take the closest ever images of the Sun. On the other, the closer we'd go, the more damaging the light we sought to collect would become.

Weird ‘Little Red Dots’ in space are something we’ve never seen Astronomers are racing to understand mysterious ancient objects that pepper James Webb Space Telescope images

Everywhere JWST looked, the telescope found at least one specimen of what are now commonly called Little Red Dots. The dots were everywhere, until they were nowhere; about 1.5 billion years after the big bang, they mostly disappear. Take a deep dive into this mystery

A nebula appears like a transparent bubble with a white edge, inside which are two hemispheres of orange clouds being blown out from the center, split by a dark vertical lane, giving the overall appearance of a see-through skull with a brain inside, as seen from above. A few stars appear with eight points, and small background galaxies can be seen around and through the outer bubble.

Side-by-side images of the same nebula show how differently it appears in near-infrared, on the left, versus mid-infrared light, on the right. The left image is labeled NIRCam and the right is labeled MIRI. In the near-infrared, the nebula’s outer bubble has a white edge and its inner clouds are orange, with a distinct dark lane cutting vertically through the centre. Stars and background galaxies appear around the nebula and through the outer bubble. In the mid-infrared, the outer bubble has a bluish tint and there is more material in the inner clouds, which are coloured off-white. The vertical dark lane is still present but more interrupted and covered by the clouds. Material appears to be erupting out the top of the nebula, and this effect is mirrored to a lesser degree at the bottom, opposite end.
